Start tractor, tractor motive power output shaft inputs to power converter 31 by power, from wearing the power take-off 29 of moving power converter 31, rotate, thereby drive the first belt pulley 34 on power take-off 29, the first gear 35 and the second belt pulley 32 rotate, the first belt pulley 34 is connected by belt with sprocket wheel belt pulley 37, thereby band movable sprocket belt pulley 37 rotates, sprocket wheel belt pulley 37 is arranged on drive sprocket axle 27, thereby drive drive sprocket axle 27 to rotate, thereby drive the drive sprocket coaxial with drive sprocket axle 27 28 to rotate, thereby drive the chain 3 on drive sprocket 28 to rotate, the first gear 35 is meshed with the second gear 36, thereby drive the second gear 36 along counter-rotation, thereby drive eccentric wheel 22 counter-rotation coaxial with the second gear 36, eccentric wheel 22 is connected with reciprocal shovel 11 with pull bar 10 by reciprocating lever 12, thereby drive back and forth shovel 11 front-rear reciprocation movements, the second belt pulley 32 is connected by belt 19 with flail knife belt pulley 14, thereby drives flail knife belt pulley 14 to rotate, and flail knife belt pulley 14 is arranged on flail knife axle 15, thereby drives flail knife axle 15 and flail knife 13 to rotate.
In advancing, by the land wheel 6 being connected with ground wheeling supporting frame 8, on ground in the middle of the cotton stalk in cotton field in row, rotate, the residual film in ground earth's surface is pricked on the land wheel moving tooth 7 of land wheel 6, with advancing of landing wheel 6, when the land wheel moving tooth 7 of pricking the residual film in earth's surface turns to the top of land wheel 6, the chain 3 and land wheel 6 move toward one another with chain moving tooth 30 of rotation, by chain moving tooth 30, the residual film on land wheel moving tooth 7 is stripped down, the rotation direction of chain 3 and land wheel 6 is the direction of advance of tractor, residual film moves upward with chain moving tooth 30 and bottom plate 33, the object of bottom plate 33 is that the residual film of peeling off not necessarily hangs on chain moving tooth 30, the residual film falling is fallen on bottom plate 33, in the continuous motion of chain 3, chain moving tooth 30 can be with residual film along bottom plate 33, to move together, when residual film arrives the top of Material collecting box for harvesting 23, the residual film on Material collecting box for harvesting 23 tops is peeled off the mutual cross action of between cog between tooth 26 utilizations and chain moving tooth 30 of peeling off on axle 25, residual film is stripped down from chain moving tooth 30, fall into Material collecting box for harvesting 23.
By the motion of tractor, the cotton field stalk of standing skews before being pushed to by frame 20, and due to the effect of stress, stalk excavates in advance from soil.By Power Drive Unit band movable eccentric wheel 22, rotate, by the reciprocating lever 12 being connected with eccentric wheel 22, drive pull bar 10 and back and forth shovel 11 and back and forth move up and down, play the effect of planing the ground, because the plane earthwork is to contrary with the direction of motion, at this moment the backward rear band of advancing reciprocal shovel 11 plane soil all digs stalk root, back and forth the plane of the shovel 11 soil degree of depth is 20-25cm, back and forth shovel 11 also plays the effect of cutting stalk simultaneously, make the root of the stalk that digs also be cut pulverizing completely, the degree of chopping arrives 3-5cm left and right, and mix with soil, overcome after later digging forward can not cross-section cutting shortcoming, along with the walking of tractor is back and forth shoveled and cut according to reciprocal speed on cotton stalk, each back and forth shovel be instrument independently, one is discharged into multiple shovel is discharged into multiple spade with another and becomes two cross sections, section edge intersects mutually.The native face that guarantees like this process all digs pulverizing through plane.On ground, the plow layer to the 25cm degree of depth has just completed the processing of ploughing, pull out, dragging for like this.
By Power Drive Unit, drive flail knife axle 15 to rotate, thereby band flail knife 13 rotations, ground is further smashed to the stalk of the 10cm degree of depth, degree 0～the 0.8cm smashing, and mix uniformly with soil, so just form layer soil structure of growing seedlings preferably, thoroughly realized the object of straw-returning.
Along with the walking of tractor, Bilateral Symmetry earthing plays cage land wheel 16, in the soil surface both sides of straw-returning, has drawn cage, is conducive to the separated of next farming and the boundary of a piece of land.The rise sheer from level ground work of straw-returning all-in-one of the residual film in cotton field cleaning has just completed like this.
Except the technical characterictic described in specification, be the known technology of those skilled in the art.
