A kind of automobile-used three axis hedge heart knife of afforestationTechnical field
The present invention relates to afforestation field more particularly to a kind of automobile-used three axis hedge heart knives of afforestation.
Background technique
Single layer blade is generally only arranged in existing grass-cutting head, and grass cuttings length is longer after cutting, is not easily cleaned, and cutter head and cuttingFace is arranged vertically, and under wind action of circling round, cutting is not smooth, and there is also dead zones for hilted broadsword header structure, and cutting effect is bad, in additionCutter head and tool apron are rigidly connected, and when encountering barrier, cutter head are be easy to cause to fracture, influence the service life.
Summary of the invention
To solve the above problems, ensure that cutting without dead the present invention provides a kind of automobile-used three axis hedge heart knife of afforestationArea can further make grass cuttings length after cutting very short, facilitate subsequent cleaning, cleaning, substantially increase operating efficiency.
Main technical schemes of the invention are as follows:
A kind of automobile-used three axis hedge heart knife of afforestation, characterized in that including housing assembly, the gear horse being mounted on housing assemblyIt reaches and cutterhead assembly, shaft coupling and transmission shaft therein is covered in by housing assembly；
Three gear motors are set on the housing assembly, and the output shaft of each gear motor passes through a shaft coupling and a transmissionAxis connection assembles a set of cutterhead assembly on every transmission shaft；
Hedgerow knife in three sets of cutterhead assemblies at least forms two rotation overlapping regions when rotating.
Further, housing assembly includes the front apron of case weld part and block in case weld part leading flank；It is describedFront apron is made using canvas filler rubber material.
Further, wherein being located at two gear motors of two sides homogeneously to synchronous rotary inwardly.
Further, the gear motor is fixed on housing assembly, and with horizontal plane at 5 °~6.5 ° top rakes.
It further, further include for fixing the cutterhead hub of hedgerow knife and pair being placed on transmission shaft in every set cutterhead assemblyThe damping block of hedgerow knife progress damping.
Further, damping stock material is rubber.
Further, arranging multiplayer is in the hedgerow knife for setting spacing on each cutterhead hub.
Further, the cutterhead hub and horizontal plane are at 5 °~6.5 ° top rakes, while making hedgerow knife and horizontal plane at 5 °~6.5 ° of inclination angles.
Further, the hedgerow knife in the cutterhead assembly of two gear motors driving of synchronous rotary is respectively and separately inwardlyHedgerow knife in outer a set of cutterhead assembly forms a rotation overlapping region.
According to above-mentioned to explanation of the invention, compared with prior art, the automobile-used three axis hedge of the afforestation that the present invention usesHeart knife, has the following beneficial effects:
Oil cylinder of the present invention uses three-axis structure, is equipped with three cutterhead assemblies, isosceles triangle arrangement, and the total Chengdu of each cutterhead carries 2Layer hedgerow knife, two sides cutterhead hub turn to the inside, and with intermediate knife capitiform at overlapping region, each further cutterheadAssembly forms 6.5 ° of top rakes with cut surface, not only ensure that and has been cut without dead zone by this scheme, but also can guarantee grass cuttings after cuttingLength is very short, facilitates subsequent cleaning, cleaning, substantially increases operating efficiency.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present inventionTechnical solution, and not intended to limit the protection scope of the present invention.
In conjunction with shown in Fig. 1 to Fig. 4, the present invention is a kind of automobile-used three axis hedge heart knife of afforestation, including housing assembly 1, toothWheel motor 2, cutterhead assembly 3, shaft coupling 4, transmission shaft 5 and hydraulic oil pipe 6 etc..
Housing assembly 1 includes case weld part 1-1 and front apron 1-2, and gear motor 2 is fixed on case weld part 1-1,With horizontal plane at 6.5 ° of inclination angles, three gear motors 2 are arranged in a triangle；Front apron is made using canvas filler rubber, both can guaranteeCasing surroundings form closed interval, and will not bend uncut grass.
Three gear motors 2 are cascaded by hydraulic oil pipe 6, and two of them gear motor 22,23 is arranged in middle partThe two sides of gear motor 21, oil inlet 22a, 23a of the gear motor 22,23 of two sides, oil outlet 22b, 23b are on the contrary, can protectCard two sides cutterhead assembly 3 rotates inwardly, and can guarantee fully synchronized, will not interfere with.
Cutterhead assembly 3 includes cutterhead hub 3-1, damping block 3-3 and hedgerow knife 3-4.Cutterhead hub 3-1 is for installing hedgerow knife 3-Be arranged on 4, cutterhead hub 3-1 multiple fixed points with setting spacing can corresponding installation multilayer hedgerow knife, in the present embodimentProvided with upper and lower two layers of hedgerow knife.Damping block 3-3 covers on transmission shaft 5, and damping block 3-3 is directly contacted with transmission shaft 5, dampingStock material is rubber, is reduced when hedgerow knife encounters barrier, generates burst external force by damping block without other rigid contactsTo the rigid shock of transmission shaft 5, the service life is improved.The output shaft of gear motor 2 is connect by shaft coupling 4 with transmission shaft 5, every biographyA set of cutterhead assembly 3 is assembled on moving axis 5, is driven by gear motor 2, does rotation fortune together with movable knife disc assembly 3 through transmission shaft 5It is dynamic.
Inner housing 3-2 and ringfeder 3-5 etc. can also be set in other embodiments.Inner housing 3-2 is covered to be filled outside transmission shaft 5Work as support frame, cutterhead hub 3-1 is fixed on inner housing 3-2, for installing hedgerow knife 3-4.Damping block 3-3 covers on transmission shaft 5,And inner housing 3-2 extruding is stuck on the shoulder of transmission shaft, then cutterhead assembly 3 is fixed on transmission shaft by ringfeder 3-5.
Three sets of cutterhead assemblies 3 are accordingly matched with three gear motors 2, are also arranged in a triangle, with horizontal plane atThe green grass cut down is taken to intermediate region and carried out finally by 6.5 ° of inclination angles, the cutterhead hub 3-1 of two sides opposite rotation inwardlyIt crushes, guarantees that green grass is cut into the very short grass cuttings of length, facilitate subsequent cleaning.Each cutterhead hub 3-1 includes upper and lower 2 layers greenGreen grass, can be cut into the length lower than 50mm, facilitate the later period by hedge knife 3-4-1,3-4-2, spacing 50mm between 2 layers of hedgerow knifeIt cleans, collects；There are certain rotation overlapping region A with intermediate hedgerow knife 3-4 by two sides hedgerow knife 3-4, guarantee cutting without deadArea.After cutterhead hub is installed in place, with horizontal plane at 6.5 ° of top rakes, while hedgerow knife and horizontal plane prevent out at 6.5 ° of inclination anglesNow it is cut with residual phenomena appearance.
When formal start to work, gear motor 2 starts, and is revolved at a high speed by shaft coupling 4, transmission shaft 5 with movable knife disc assembly 3Turn, forms hedgerow knife 3-4 to the cutting force of green grass, complete the trimming to green grass.
Using three-axis structure, three cutterhead assemblies, isosceles triangle arrangement are equipped with, the total Chengdu of each cutterhead carries 2 layers of hedgerowKnife, two sides cutterhead hub turn to the inside, and with intermediate knife capitiform at rotation overlapping region, each further cutterhead is totalCheng Junyu cut surface formed 6.5 ° of top rakes, by this scheme not only ensure that cutting without dead zone, but also can guarantee cutting after grass cuttings it is longDegree is very short, facilitates subsequent cleaning, cleaning, substantially increases operating efficiency.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the artFor member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformationsAlso it should be regarded as protection scope of the present invention.
