Automatic livestock injectorTechnical Field
The invention relates to the technical field of automatic livestock injectors, in particular to an automatic livestock injector.
Background
China imports a plurality of meat foods such as pork, beef and the like from foreign countries every year, the quantity of the meat foods is large every year, and the development of the breeding industry is encouraged in the country at present. One of the most troublesome problems for the livestock breeding industry is that the livestock is ill, and once ill, the livestock may be infected with viruses, so that the livestock in the whole farm die, and the livestock are lost greatly, which requires that the bred livestock are often vaccinated or the livestock are injected with medicines in time when ill, so as to avoid the spread and influence on other livestock. There are a lot of livestock in the plant the inside, manual injection, need plenty of time and manpower, intensity of labour and work efficiency have been reduced, consequently, automatic injection has been had, however, automatic injection also has a problem, during the injection, the livestock is because painful, the body twists easily, cause the syringe needle to break away from, and automatic injection has not stopped yet, the liquid medicine will be extravagant like this, when waiting to stop switch, the liquid medicine has spilled a lot, cause the waste, consequently, need to accomplish automatic injection and can conveniently stop the injection syringe of avoiding the waste.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 5, the present invention provides a technical solution of an automatic injector for livestock: the utility model provides a livestock autoinjector, includesinjection tube 1, electronic push-and-pull mechanism, limitingplate 2 and trigger mechanism, andinjection tube 1 sets up to two of parallel, and the speed of two injections is faster, simultaneously, also can inject different medicines, improves injection efficiency.
The lower end of theinjection tube 1 is connected with aneedle 11, apiston 12 is arranged in theinjection tube 1, and thepiston 12 is connected with apiston rod 13.
The electric push-pull mechanism is arranged on theinjection tube 1 and can drive thepiston rod 13 to move through electric work to inject livestock; the electric push-pull mechanism comprises apull plate 3 fixed between the end parts of twopiston rods 13, and aguide plate 31 and atransverse plate 32 fixed between twoinjection tubes 1, wherein theguide plate 31 is positioned between thetransverse plate 32 and thepull plate 3, a threadedcylinder 33 vertically penetrating through theguide plate 31 is fixed on thepull plate 3, the cross section of the outer end of the threadedcylinder 33 is square, aguide hole 34 corresponding to the threadedcylinder 33 is formed in theguide plate 31, a threadedrod 35 matched with the threadedcylinder 33 is installed in the threadedcylinder 33, the threadedrod 35 penetrates through thetransverse plate 32 and is connected with amotor 36, the threadedrod 35 is rotatably connected with thetransverse plate 32, astorage battery 37 is installed on themotor 36, power is supplied by thestorage battery 37, the motor 26 drives the threadedrod 35 to rotate so as to drive the threadedcylinder 33 to be pulled, the threadedcylinder 33 is driven to move, and the guide hole.
Thelimiting plate 2 is arranged at one end of theinjection tube 1 close to theneedle head 11, thelimiting plate 2 is provided with aneedle hole 21 for theneedle head 11 to pass through, the trigger mechanism is arranged at one end of the limitingplate 2 contacted with livestock and controls the action of the electric push-pull mechanism when being extruded to inject or draw the medicine, the trigger mechanism comprises a forward andreverse switch 4 which is fixed on thelimiting plate 2 and is electrically connected with amotor 36, the other end of the forward andreverse switch 4 is electrically connected with astorage battery 37, the forward andreverse switch 4 is arranged at one side of theinjection tube 1, the forward andreverse switch 4 is provided with a push typeforward button 41 and areverse button 42, theforward button 41 is fixed with atouch block 43 which passes through thelimiting plate 2, thelimiting plate 2 is provided with amounting hole 44 for thetouch block 43 to move and stretch when being touched, thelimiting plate 2 is provided with anoperating hole 45 which is corresponding, sucking the liquid medicine.
When the livestock is injected, the skin of the livestock extrudes thetouch block 43 on thelimiting plate 2, so as to extrude theforward rotation button 41, themotor 36 drives the threadedrod 35 to rotate, so as to drive the threadedcylinder 33 and thepiston rod 13 to inject, once the livestock runs off, thetouch block 43 is separated, themotor 36 stops, only thetouch block 43 is pressed all the time, themotor 36 always works and is a common switch on the market, thus, the liquid medicine is prevented from being spilled when the livestock runs off, the over-current relay is arranged in themotor 36, the liquid medicine can not be completely used up after one-time injection, because of the twoinjection cylinders 1, the injection of a plurality of livestock is convenient, the distance from one end of the injection is shortened each time, once thepiston 12 reaches the bottom of theinjection cylinder 1, themotor 36 is easy to be burnt out, the phenomenon that themotor 36 is burnt out due to the over-current can not occur due to the over-current,guide cylinder 22 is transparent, mainly be the scale mark on conveniently observinginjection tube 1, confirm the injection volume, and limitingplate 2 fixes the bottom atguide cylinder 22,guide cylinder 22's circumference threaded connection has theinner fastening knob 23 of supportinginjection tube 1 tightly, limitingplate 2 limits the depth of insertion ofsyringe needle 11, loosenfastening knob 23 soon, be convenient for adjustsyringe needle 11's the degree of depth, confirm the injection depth, fasteningknob 23's threaded end cup joints the support section ofthick bamboo 24 of fixing onguide cylinder 22, and support section ofthick bamboo 24 and fasteningknob 23 threaded connection, increasefastening knob 23's connection length, fixed effect is better, limitingplate 2 is the arc of conveniently laminating the livestock, be difficult to slide, the skin of laminating livestock.
The working principle is as follows: when the injection device is used, firstly, theneedle 11 is inserted into liquid medicine, thereverse rotation button 42 is pressed through theoperation hole 45, themotor 36 drives the threadedrod 35 to rotate, so as to drive the threadedcylinder 33 to move, thepiston rod 13 is pulled to suck the liquid medicine, after the liquid medicine is loosened, themotor 36 stops working, theinjection tube 1 is held by hand and is aimed at the hip of livestock to inject, when theneedle 11 is inserted, thelimiting plate 2 can be propped against the skin of the livestock to limit theneedle 11 from further going deep, thetouch block 43 is squeezed, thetouch block 43 squeezes theforward rotation button 41, themotor 36 works to drive thepiston 12 to advance and inject, here, the injection is automatic, the injection is easy, the manual injection is not needed, once the livestock shakes greatly, theneedle 11 is separated, the needle can leave thetouch block 43, so as to loosen theforward rotation button 41, the injection is stopped automatically, the liquid, here adopt twoinjection tubes 1, like this, just shortened injection time, it is fast, efficient, twoinjection tubes 1 also can be different liquid medicines, just once can accomplish the injection, moreover, twoinjection tubes 1 deposit the dose big, absorb the liquid medicine at every turn, can inject a plurality of livestock, only need confirm the injection volume through the scale mark oninjection tube 1 at every turn, perhaps confirm the injection volume according to injection time, and efficiency is higher, need not every animal and all absorbs a liquid medicine.
