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 also field dual mode of dry land and paddy field.During dry land, a kind of is to utilize harvest machinery configuration straw chopping apparatus, in results, the stalk in the feeding machine is shredded and sheds the field again, completes the also field operation of stalk, but can not the root stubble that be retained in the field after harvesting be shredded.In addition, stalk, root stubble direct mulching and returning in to soil cultivation after utilizing exactly reversal stubble cleaning rotary cultivator to results, but not to the chopping effect of straw stubble; General straw crushing and field-returning machine, multiplex in the chopping and returning of the hard stalks such as corn, Chinese sorghum, the multiplex flail knife of crushing knife or hammer pawl, the main form such as clash into, tear that relies on is completed pulverizing, be used for the rice and wheat straw crushing effect bad, stalk, the root stubble that pastes ground also can't be pulverized to lodging, rolling.During the paddy field, paddy-field stubble-embedding commonly used plays the facility such as pulp grinder, paddy field driving harrow, can only carry out mulching and returning to stalk, root stubble, but can not shred, and at stalk, when root stubble amount is larger, field effect can't satisfy 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 comprises Cardan shaft, is provided with the power shaft protective cover at the Cardan shaft top, and power shaft protective cover top is provided with the hanger bracket assembly; Cardan shaft is connected with the idler gear box assembly, the idler gear box assembly through after speed change by left transverse axis, right transverse axis respectively with the side gear box assembly be connected the belt transmission assembly and be connected; The side gear box assembly drives rotary ploughing cutter shaft rotation by rotating shaft, in rotary ploughing cutter shaft both sides, side plate is housed; Chopping belt transmission assembly drives the rotation of shredder bar axle assembly, at shredder bar axle assembly top installation case; It is characterized in that: lower roller and upper roller are housed in the middle of rotary ploughing cutter shaft and shredder bar axle assembly, and upper roller is connected with right transverse axis by the belt conveyor drive assembly, and upper roller drives lower roller and rotates; Be provided with grass guide board between upper roller and lower roller.
The side plate of described right transverse axis one side is provided with the U-shaped hole, and the upper roller adjusting device is bolted on the U-shaped hole, and the upper roller adjusting device can move to regulate along the U-shaped hole position of upper roller.
Lower roller and upper roller move toward one another.
Moving knife and stationary knife are installed on the shredder bar axle assembly.
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: the contrary rotary-cut of the cutter shaft stubble of being completely cured before adopting, and the stalk of leaving in the gathering working width and root stubble are carried backward, rear cutter shaft has supporting chopping rice and wheat straw root stubble, can realize the full dose mincing and returning to the field of rice and wheat straw root stubble, especially can carry out mincing and returning to the field to lodging, the straw stubble that rolls or overwhelm between rut during operation, power consumption is few, and is adaptable; Chopping length changes feeding speed by conveying roller turriform belt, and is easy to adjust; On rotary ploughing cutter shaft, rotary blade adopts people's word arrangement, can cut off the root stubble, and stalk, root stubble are carried backward, only cuts surface soil, and is simple in structure, and apolegamy is convenient; The chopping of straw stubble adopts hobboing cutter to coordinate with stationary knife, and cutting mode is for there being the supporting cutting, and laborsaving, power consumption is few; Hobboing cutter is arranged on the chopping rotor and is adopted the symmetric helix formula to arrange, stable working.
