The vertical direction may be the direction shown by the Z-axis in fig. 1.
The material chamber 21 is used for containing the mix to be sprayed.
The specific structure of the rotational connection of the control ring 22 and the base 11 and the driving structure of the control ring 22 can be selected from the existing structures, and will not be described here.

A plurality of discharge through holes 32 are provided for receiving the mix.
The side of the discharge cylinder 31 near the second side 16 may abut against the base 11 such that the base 11 is able to close the port of the discharge through hole 32 near the base 11, i.e. the port of the discharge through hole 32 near the base 11 is covered by the base 11 when the discharge through hole 32 is dislocated from the first through hole 12 and the second through hole 14. Of course, other components may be provided on the base 11 to block the port of the discharge through hole 32.
The blocking portion 33 enables the bottom port of the discharge through-hole 32 to be blocked, so that the mix entering the discharge through-hole 32 does not leak out of the bottom port of the discharge through-hole 32.
The notch 34 of the blocking part 33 makes the discharge through hole 32 facing the notch 34 not blocked by the blocking part 33 after the discharge cylinder 31 rotates to a certain angle, and the mixture in the discharge through hole 32 can leak out.
The first state and the second state of the discharge cylinder 31 are switched by driving the discharge cylinder 31 to rotate, specifically, when the discharge cylinder 31 rotates to a certain angle, a certain discharge through hole 32 corresponds to the first through hole 12 of the base 11, the mixing material in the material cavity 21 can enter the discharge through hole 32 through the first through hole 12, then the discharge cylinder 31 continues to rotate until the discharge cylinder 31 is switched to the second state, and the discharge through hole 32 containing the mixing material rotates to the notch 34 of the blocking part 33, so that the mixing material can be discharged.
Furthermore, by reasonably controlling the rotation of the discharge cylinder 31 and the control ring 22, in the second state, the plunger member 23 is synchronized from the second through-hole 14 into the discharge through-hole 32, so that the mix can be pushed out through the plunger member 23 and into the spray member.
The spraying component is used for achieving the purpose of spraying the mixture.
In the embodiment of the application, the volume of the mixing material entering the discharge through hole 32 is fixed because the volume of the discharge through hole 32 is fixed, and the discharge amount of the mixing material in unit time can be controlled by controlling the rotation of the discharge cylinder 31 and the control ring 22, so that the purpose of quantitatively supplying the mixing material is realized. Referring to fig. 2 and 9, in some embodiments, the spray member includes a discharge portion 41, the discharge portion 41 being disposed at the notch 34, the discharge portion 41 being provided with a discharge passage 42, an inlet of the discharge passage 42 being disposed below the second through hole 14.
An inlet of the discharge passage 42 is provided below the second through hole 14, and when the discharge cylinder 31 is rotated to the discharge through hole 32 containing the mix is moved to the gap 34, the mix in the discharge through hole 32 is discharged into the discharge passage 42.
Referring to fig. 2, in some embodiments, the spray assembly further includes a spray channel 51 and a gas source channel 52. The spray channel 51 communicates with the discharge channel 42 and the air source channel 52 communicates with the spray channel 51.

The air source channel 52 is used for inputting air into the spraying channel 51, so that the mixture is discharged at a certain initial speed, and the purpose of spraying slurry is realized.
Referring to fig. 2, in some embodiments, the material chamber 21 is movably connected to the base 11 in a vertical direction, the base 11 is provided with a communication channel 13, the communication channel 13 is communicated with the first through hole 12, the material outlet channel 29 is movably communicated with the communication channel 13, and an elastic member 210 is provided between the material chamber 21 and the base 11.
The resilient member 210 may be a spring, the resilient member 210 being adapted to provide a resilient force that urges the cavity 21 away from the first side 15, i.e. the cavity 21 is raised.
The specific manner in which the material chamber 21 and the base 11 are movably connected may be selected from existing structures, and will not be described in detail herein.
The discharging channel 29 is communicated with the first through hole 12 through the communicating channel 13, so that the contact area is larger and the installation is more convenient compared with the direct communication of the discharging channel 29 and the first through hole 12.
The material chamber 21 is movably connected to the base 11, along with the continuous discharging of the material chamber 21, under the action of the elastic restoring force of the elastic piece 210, the material chamber 21 is gradually far away from the first side 15, and then the abutting portion 24 is gradually far away from the first side 15, on one hand, the position of the material chamber 21 is observed to play a role in prompting, and an operator can be timely reminded to supplement materials. On the other hand, when the abutting portion 24 is away from the first side 15, the length of the plunger member 23 inserted into the discharge through hole is reduced, which can serve to reduce wear of the plunger member 23 and increase the service life of the plunger member 23.
Referring to fig. 2, in some embodiments, the discharge channel 29 is interposed in the communication channel 13.
The discharging channel 29 is inserted in the communicating channel 13, so that the discharging channel 29 can be communicated with the communicating channel 13, and meanwhile, the discharging channel 29 can move relative to the communicating channel 13, and the risk that the discharging channel 29 is disconnected from the communicating channel 13 when the material cavity 21 moves is reduced.
Referring to fig. 2, 3, 5, and 6, in some embodiments, the plunger member 23 includes a body 26, a rotating portion 27, and a moving portion 28. The main body 26 is connected to the control ring 22 movably in the vertical direction. The rotating portion 27 is rotatably connected to the main body 26, the rotation axis of the rotating portion 27 extends along the vertical direction, the rotating portion 27 is provided with a poking portion 213, the base 11 is provided with a second abutting inclined surface 215, and when the second abutting inclined surface 215 is configured to be in the second state of the discharge cylinder 31, the poking portion 213 abuts against the second abutting inclined surface 215, so that the rotating portion 27 rotates.
The specific structure of the rotational connection of the rotating portion 27 and the main body 26 may be selected from the existing structures, and will not be described here.
The second abutment ramp 215 may gradually approach the control ring 22 in the direction of rotation of the control ring 22.
When the control ring 22 rotates, the plunger member 23 passes the second abutment inclined surface 215, and the toggle portion 213 can abut against the second abutment inclined surface 215, so that the rotating portion 27 can rotate under the action of the second abutment inclined surface 215.
The moving part 28 is movably connected to the main body 26 along the vertical direction, the moving part 28 is arranged on one side of the rotating part 27 close to the first side 15, a plurality of convex teeth 211 are respectively arranged on the opposite sides of the moving part 28 and the rotating part 27, the convex teeth 211 are circumferentially arranged around the rotation axis of the rotating part 27, and the convex teeth 211 of the moving part 28 are meshed with the convex teeth 211 of the rotating part 27.
The specific structure of the movable connection between the movable portion 28 and the main body 26 may be selected from the existing structures, and will not be described here. Note that the moving portion 28 can move only along the rotation axis of the rotating portion 27, and cannot rotate relative to the main body 26.
A spring may be provided between the moving portion 28 and the main body 26 to provide an elastic force for moving the moving portion 28 toward the rotating portion 27, and a spring may be provided between the rotating portion 27 and the main body 26 to return the rotating portion 27.
The contact surface of the teeth 211 of the moving part 28 and the teeth 211 of the rotating part 27 may be inclined surfaces, so that when the rotating part 27 rotates, the teeth 211 of the moving part 28 and the rotating part 27 can be dislocated, and further the moving part 28 can move away from the rotating part 27 under the action of the teeth 211.
When the rotating part 27 rotates, the moving part 28 moves away from the rotating part 27 under the action of the convex teeth 211, namely, the moving part 28 plays a role in compensation, specifically, during discharging, the main body 26 is driven by the abutting part 24 to push the mixture, so that the discharging effect on the mixture is limited, and after the main body 26 is inserted into the discharging through hole 32, the moving part 28 is driven by the rotating part 27 to push the mixture further, and the discharging effect on the mixture is increased.
It should be noted that, when the cavity 21 is raised, the amount of the mixture that can enter the discharge through hole 32 is small because the material in the cavity 21 is in a shortage state, and the fluidity of the mixture is good, so that the plunger member 23 can still satisfy the discharge effect although the length of the plunger member inserted into the discharge through hole 32 is reduced. However, there is a risk that the discharge amount has an error at this time, and this problem can be solved by setting an error threshold, that is, when the error of the discharge amount is within the allowable range, the slurry spraying can be continued, and if the error exceeds the threshold, the material is fed in time, so as to eliminate the error.
Referring to fig. 2 and 3, in some embodiments, the main body 26 is provided with a limiting cavity, an opening is disposed on a side of the limiting cavity near the first side 15, the rotating portion 27 and the moving portion 28 are inserted into the limiting cavity through the opening of the limiting cavity, the main body 26 is provided with a limiting channel 222, and the toggle portion 213 is connected to the rotating portion 27 through the limiting channel 222.
The moving part 28 and the rotating part 27 are accommodated in the limiting cavity, on one hand, the moving part 28 and the rotating part 27 can be protected by the main body 26, and on the other hand, the moving part 28 can move relative to the main body 26 under the action of the limiting cavity.
Referring to fig. 3, 4, 7 and 8, in some embodiments, the rotating portion 27 is provided with an air inlet channel 212, the moving portion 28 is provided with an air outlet channel 219, the stirring portion 213 is provided with an air channel 214, the air channel 214 is communicated with the air inlet channel 212, the stirring portion 213 is movably connected to the rotating portion 27, a moving direction of the stirring portion 213 is perpendicular to a rotation axis of the rotating portion 27, a side of the stirring portion 213 away from the rotating portion 27 is a cylindrical structure 220 with an axis parallel to the rotation axis of the rotating portion 27, an inlet of the air channel 214 is arranged on a side wall surface of the cylindrical structure 220, the base 11 is provided with an air outlet 216, the air outlet 216 is arranged above the second abutting inclined surface 215, the air outlet 216 comprises an arc surface 221, the air outlet 216 is provided with an air outlet channel 217, and an outlet of the air outlet 217 is arranged on the arc surface 221.
The inlet of the air outlet passage 219 of the moving part 28 may be provided at a side of the moving part 28 facing the rotating part 27, and the outlet may be provided at a side near the discharge through hole 32. And the outlet of the air inlet channel 212 of the rotating part 27 may be disposed on the side of the rotating part 27 facing the moving part 28, so that the air inlet channel 212 can be communicated with the air outlet channel 219, and under the action of the cavity enclosed by the limiting cavity, the air of the air inlet channel 212 can enter the air outlet channel 219 and be discharged from the outlet of the air outlet channel 219.
The advantage of this arrangement is that when the toggle portion 213 is engaged with the second abutment ramp 215, the toggle portion 213 has a tendency to move away from the rotating portion 27 due to friction, and the moment arm of the toggle portion 213 applying a torque to the rotating portion 27 increases, facilitating the rotation of the rotating portion 27.
A spring may be provided between the toggle portion 213 and the rotation portion 27 so that the toggle portion 213 can be reset.
When the toggle portion 213 moves relative to the rotating portion 27, the air passage 214 and the air intake passage 212 are kept in a communicating state, and the communicating manner of the air passage 214 and the air intake passage 212 may be selected from the existing structures, for example, may be through a deformable soft passage.
When the material cavity 21 is lifted to a certain position, the stirring portion 213 is away from the second abutment inclined surface 215, and at this time, when the control ring 22 rotates, the stirring portion 213 cannot contact the second abutment inclined surface 215, and contacts the exhaust end 216 located above the second abutment inclined surface 215.
The exhaust passage 217 of the exhaust end 216 is used for exhausting gas, and the exhaust passage 217 can be controlled to exhaust gas by the gas source device 218 by communicating the exhaust passage 217 with the gas source device 218 like an air compressor.
By reasonably setting the position of the exhaust end 216 relative to the stirring portion 213, when the stirring portion 213 passes through the exhaust end 216, the cylindrical structure 220 of the stirring portion 213 can abut against the arc surface 221 of the exhaust end 216, and the two are fully contacted, at this time, the outlet of the exhaust channel 217 is communicated with the inlet of the air channel 214, and the gas in the exhaust channel 217 can enter the air channel 214 and then enter the air inlet channel 212 of the rotating portion 27. Further, since the toggle portion 213 is movably connected to the rotating portion 27, when the plunger member 23 is further moved, the cylindrical structure 220 rotates relative to the arc surface 221 within a certain range, that is, the exhaust passage 217 and the air passage 214 can be kept in communication, so that the time during which the exhaust passage 217 and the air passage 214 can be in communication is increased, and the amount of gas that can be input into the intake passage 212 is increased. The plunger member 23 then moves further with the control ring 22, whereupon the cylindrical structure 220 and the arcuate surface 221 disengage and the vent passage 217 may cease venting.
The gas in the gas inlet passage 212 can enter the gas outlet passage 219 of the moving part 28 and then enter the gas outlet through hole, and the mixture in the discharge through hole 32 can be discharged under the action of the gas, so that on one hand, the discharge through hole 32 can be cleaned after the slurry spraying is finished, and on the other hand, when the length of the plunger member 23 inserted into the discharge through hole 32 is reduced, the gas can be input into the discharge through hole 32 to assist the discharge.
Further, when the stirring portion 213 passes through the exhaust end 216, the rotating portion 27 rotates under the action of the protruding teeth 211, so that the moving portion 28 can move away from the rotating portion 27, and a certain gap can exist between the rotating portion 27 and the moving portion 28, and the gap can store part of gas, so that the air outlet channel 219 still maintains the exhaust for a certain time after the stirring portion 213 is separated from the exhaust end 216, and the moving portion 28 can be inserted into the exhaust through hole, so that the gas can be input into the exhaust through hole 32.
It should be noted that the inlet channels 212 and the outlet channels 219 are shown only in partial configuration due to the cross-sectional view.
In some embodiments, the axis of the inlet section of the air intake passage 212 is perpendicular to the rotation axis of the rotation portion 27, and the toggle portion 213 is inserted into the inlet section of the air intake passage 212.
The stirring portion 213 is inserted into an inlet section of the air intake passage 212, so that the air passage 214 of the stirring portion 213 can be kept in communication with the air intake passage 212 of the rotating portion 27 while the stirring portion 213 can be moved relative to the rotating portion 27. The sealing structure between the toggle part 213 and the rotary part 27 may be selected among existing structures.
Referring to fig. 7, in some embodiments, the first abutment ramp is provided with a flange on both sides thereof, in the radial direction of the rotation circumference of the control ring 22.
The ribs act as a stop for the body 26.
The ribs can increase the accuracy of the mating of the body 26 and the first abutment ramp, reducing the risk of the body 26 becoming disengaged from the first abutment ramp when the first abutment ramp applies a force to the body 26.
The ribs also increase the strength of the connection between the body 26 and the control ring 22, limiting the body 26 by the ribs reduces the risk of bending or displacement of the body 26, resulting in a broken connection between the body 26 and the control ring 22.
In the embodiment of the present application, stirring blades 25 may be disposed in the cavity 21 according to the properties of the mixture.
For example, for a mix that may solidify after rest, a stirring blade may be provided in the cavity 21, and the mix is stirred by the stirring blade 25, reducing the risk of solidification of the mix.
The above embodiments are only illustrative of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention, and various modifications, alterations, and substitutions made by those skilled in the art to the technical solution of the present invention should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
