Description
Technical field
The present invention relates to agricultural machinery technological field, especially relate to a kind of rice and wheat straw root stubble and cut up and farmland returned machine.
Background technology
General rice and wheat straw mechanization direct returning to farmland, has dry land and paddy field also two kinds, field mode.During dry land, one utilizes harvest machinery to configure straw chopping apparatus, shreds and shed field again, complete the also field operation of stalk, but can not shred the root stubble being retained in field after harvesting while results to the stalk in feeding machine.In addition, utilize reversal stubble cleaning rotary cultivator to the stalk after results, root stubble direct mulching and returning while to soil cultivation exactly, but not to the chopping effect of straw stubble; General straw crushing and field-returning machine, be used for the chopping and returning of the hard such as corn, Chinese sorghum stalk, the multiplex flail knife of crushing knife or hammer pawl, form completes pulverizing mainly to rely on shock, tear etc., bad for rice and wheat straw crushing effect, also cannot pulverize lodging, the stalk rolling subsides ground, root stubble.During paddy field, conventional paddy-field stubble-embedding plays the facility such as pulp grinder, paddy field driving harrow, can only carry out mulching and returning, but can not shred stalk, root stubble, and when stalk, root stubble amount are larger, field effect can't meet agriculture requirement.
Summary of the invention
For overcoming the problems referred to above, solve rice and wheat straw and root stubble crushing effect problem of poor, the technical solution used in the present invention is as follows:
A kind of rice and wheat straw root stubble cuts up and farmland returned machine, and comprise Cardan shaft, be provided with power shaft protective cover at Cardan shaft top, power shaft protective cover top is provided with hanger bracket assembly; Cardan shaft is connected with idler gear box assembly, idler gear box assembly after speed change by left transverse axis, right transverse axis respectively with side gear box assembly with shred belt transmission assembly and be connected; Side gear box assembly drives rotary ploughing cutter shaft to rotate by rotating shaft, in rotary ploughing cutter shaft both sides, side plate is housed; Chopping belt transmission assembly drives shredder bar axle assembly to rotate, and installs case at shredder bar axle assembly top; It is characterized in that: in the middle of rotary ploughing cutter shaft and shredder bar axle assembly, lower roller and upper roller are housed, upper roller is connected with right transverse axis by belt conveyor drive assembly, and upper roller drives lower roller to rotate; Grass guide board is provided with between upper roller and lower roller.
The side plate of described right transverse axis side is provided with U-shaped hole, and upper roller adjusting device is bolted on U-shaped hole, and upper roller adjusting device can move the position regulating upper roller along U-shaped hole.
Lower roller and upper roller move toward one another.
Shredder bar axle assembly is installed moving knife and stationary knife.
Described rotary ploughing cutter shaft counterclockwise rotates.
Rotary blade on described rotary ploughing cutter shaft is circular array.
The rotary ploughing cutter shaft rotary tillage degree of depth≤2cm.
Advantage of the present invention: before adopting, cutter shaft to be completely cured stubble against rotary-cut, and the stalk left over drawn in working width and root stubble are carried backward, rear cutter shaft has supporting chopping rice and wheat straw root stubble, the full dose mincing and returning to the field of rice and wheat straw root stubble can be realized, especially can to lodging, roll or operation time rut between the straw stubble that overwhelms carry out mincing and returning to the field, power consumption is few, adaptable; Chopping length changes feeding speed by conveying roller turriform belt, easy to adjust; On rotary ploughing cutter shaft, rotary blade adopts people's word arrangement, can cut off root stubble, and stalk, root stubble are carried backward, only cut surface soil, and structure is simple, and apolegamy is convenient; The chopping of straw stubble adopts hobboing cutter to coordinate with stationary knife, and cutting mode is for there being supporting cutting, and laborsaving, power consumption is few; Hobboing cutter arrangement on chopping rotor adopts the arrangement of symmetric helix formula, stable working.
