From one end of the W-shaped support arm 1 to the other end, there are a first inflection point, a second inflection point and a third inflection point. The residual film roller fixing device 3 is arranged at the first inflection point near one end of the W-shaped support arm 1; the residual film roller fixing device 3 comprises a fourth rotating shaft 1.2 passing through the first inflection point on the W-shaped support arm, a first residual film roller fixing shaft 3.5, a second residual film roller fixing shaft 3.7, a limiting push rod 3.4, a limiting wheel 3.3, a fixed block 3.2 and a shell 3.8; one end of the fourth rotating shaft 1.2 is toothedly connected with the first residual film roller fixing shaft 3.5 through a gear, so as to drive the first residual film roller fixing shaft 3.5 to rotate, thereby driving the residual film roller 9 to rotate through the first residual film roller fixing shaft 3.5, and then winding the residual film to realize recycling; the limiting wheel 3.2 is fixedly connected with the outer side end of the second residual film roller fixing shaft 3.7; the limiting push rod 3.4 is movably clamped on the limiting wheel 3.2, and the limiting push rod 3.4 is arranged outside the shell 3.8; the limiting push rod 3.4 is rotatably connected with the shell 3.8 through a vertically arranged fifth rotating shaft 3.1, so as to realize that the limiting push rod 3.4 can swing left and right, and simultaneously drive the limiting wheel 3.2 to move left and right, thereby driving the second residual film roller fixing shaft 3.7 to extend and retract; the second residual film roller fixing shaft 3.7 passes through the fixed block 3.2, and forms a limit through the fixed block 3.2; meanwhile, the inner side of the second residual film roller fixing shaft 3.7 is arranged outside the shell 3.8 relative to the first residual film roller fixing shaft 3.5; the first residual film roller fixing shaft 3.5 and the second residual film roller fixing shaft 3.7 are inserted into the residual film roller 9 to realize clamping; the auxiliary roller 5 is arranged at the third inflection point of the W-shaped support arm 1; the auxiliary roller 5 is toothedly connected with the gear on the second rotating shaft 1.5 through a gear, so as to realize rotation of the auxiliary roller 5 through rotation of the second rotating shaft 1.5. The second rotating shaft 1.5 is arranged at the third inflection point of the W-shaped support arm 1, and the third rotating shaft 1.4 is arranged at the second inflection point; the first rotating shaft 7 is connected with the second rotating shaft 1.5 through a chain 1.3; the second rotating shaft 1.5 is connected with the third rotating shaft 1.4 through the chain 1.3; the third rotating shaft 1.4 is connected with the fourth rotating shaft 1.2 through the chain 1.3; the width between the walking wheels 6 is greater than the width of the mulch film; the height of the support frame between the mulch forks 8 from the ground is greater than the height of the seedling.

[0025] The power vehicle is a tractor or a farm machine.

[0026] The chain 1.3 can be replaced by a belt.

[0027] The hydraulic push rod 2 is connected to the power vehicle, and the extension and retraction of the hydraulic push rod 2 is controlled by the power vehicle switch, so as to realize the lifting of the W-shaped supporting arm 1.

[0028] The elastic fixing strip 3.6 is provided on the connecting end of the residual film roller 9 and the first residual film roller fixing shaft 3.5, and the outer diameter of the elastic fixing strip 3.6 is greater than 0.5-3 mm when it is not subjected to external force, so that a certain extrusion force is formed between the two, but it is not completely fixed.

[0029] The brush plate 4 is further provided between the residual film roller fixing device 3 and the auxiliary roller 5, and the brush plate 4 is fixed on the W-shaped supporting arm 1 by screws. The residual film passes through the brush gap in the middle of the brush plate 4, so that the residual film is cleaned by the brush during movement, thereby effectively removing impurities contained in the residual film.

[0030] In one embodiment of the present application, two brush rollers (not shown in the figure) are further provided between the residual film roller fixing device and the auxiliary roller 5. The two brush rollers are oppositely arranged in an up-down manner, one rotates forward and the other rotates backward, and are controlled by two 12V motors. The 12V motor is connected to the power supply of the electric motor vehicle. The residual film passes through the two brush rollers during collection, and the forward and reverse rotation of the brush rollers realizes the cleaning of impurities and dust.

[0031] The mulch fork 8 is triangular in structure, with the inside being high and the two sides being low. During use, the residual film is inserted into the bottom of the two ends, and then the inclined surface extending upward lifts the mulch and also turns the soil on both sides of the mulch to the two sides, thereby improving the purification rate of the mulch.

[0032] The double-sided adhesive tape 9.1 is provided on the outer side of the residual film roller 9. When the residual film recycling starts, the residual film passing through the brush plate 4 is wound on the residual film roller 9 and then stuck on the double-sided adhesive tape 9.1, and then the residual film is continuously wound and recycled during the rotation of the residual film roller 9.

[0033] The second residual film roller fixing shaft 3.7 moves outward when the limiting push rod 3.4 pushes inward, and the inner end is parallel to the shell 3.8, which further improves the installation and removal efficiency of the residual film roller 9.

[0034] The width between the walking wheels 6 is greater than the width of the mulch and the field ridge.

[0035] Exemplary, the minimum diameter of the residual film roller 9 is greater than one third of the diameter of the walking wheel, the rotational speed is greater than 3 times the rotational speed of the walking wheel, and the clamping force of the elastic fixing strip on the residual film roller is less than the tearing force that the residual film can withstand. Further, when the rotational speed of the residual film roller 9 is too fast, the first residual film roller fixing shaft 3.5 can rotate relative to the residual film roller 9, and at the same time, the residual film will not be torn. Since the diameter of the residual film roller 9 increases with the recovery of the residual film, the problem of different rotational speeds between the residual film roller and the walking wheel is well solved by this technical solution.

[0036] Working principle and working process: In the working process, first, the pre-planting residual film recovery machine is connected with the power vehicle through the power vehicle connecting hole 1.1, and then the hydraulic push rod is also connected with the power vehicle. The side of the empty residual film recovery cylinder is pasted with double-sided tape 9.1, then the limiting push rod 3.4 is pushed, the limiting wheel 3.3 moves outward, driving the second residual film roller fixing shaft 3.7 to move outward, then the first residual film roller fixing shaft 3.5 end is inserted into the residual film roller 9, and the elastic fixing strip 3.6 provided at the end is clamped. Then pull the limiting push rod 3.4 to clamp the residual film fixing barrel. Then lift one end of the residual film, make it pass over the upper end of the auxiliary roller 5, then pass through the brush plate 4, and stick on the double-sided tape after winding on the residual film roller 9. Then start the device to move forward, the film fork is inserted into both ends of the residual film to remove the soil covering both ends. The walking wheel 6 contacts the ground to rotate, thereby driving the first rotating shaft 7 to rotate, and driving the second rotating shaft 1.5, the third rotating shaft 1.4 and the fourth rotating shaft 1.2 to rotate. The fourth rotating shaft 1.2 drives the first residual film roller fixing shaft 3.5 to rotate through gear set. Further, the residual film roller 9 is driven to rotate by the elastic fixing strip 3.6. The residual film roller 9 drags the residual film, and at the same time, the residual film is recovered under the friction of the auxiliary roller 5 and the action of the film fork 8. Since the walking wheel walks on both sides of the seedling, and the distance between the supporting frames of the film fork 8 is higher than the height of the seedling from the ground, the seedling growth will not be affected during the recovery process. At the same time, the brush plate 4 sweeps the residual film passing through it up and down to remove dust and impurities. The recovered residual film is wound on the surface of the residual film roller 9. The disassembly is completed by adjusting the second residual film roller fixing shaft 3.7. Pre-planting recovery, since the residual film has been in the ground for a relatively short time, it is less weathered, so its integrity, toughness and recovery value are higher. The pre-planting residual film recovery machine described in the present application can well realize pre-planting recovery, and the recovered seedling has higher application value, better cleanliness, lower recovery cost, and directly forms an unfolded residual film, effectively reducing the workload of further processing in the later stage.
