[0002] Existing drum-type residual film recycling machines usually use an agricultural tractor for traction and the rear output shaft of the agricultural tractor for driving; under the drive of the rear output shaft of the agricultural tractor, the grid conveyor device conveys soil, root stubbles, and plastic films backward. During the conveying process, the grid conveyor device can automatically discharge part of the soil, and a small part of the soil, root stubbles, and plastic films are conveyed into the drum sieve. The drum sieve is generally cylindrical and has a grid structure. Under the action of the transmission mechanism, the drum sieve rotates, and the root stubbles and plastic films are screened out and conveyed into the collection box at the rear.

[0003] This kind of residual film recycling machine can recycle residual films, and at the same time, it can also collect root stubbles, and the root stubble soil removal effect is good; however, there are mainly the following problems in actual use: some of the plastic films wrapped around the root stubbles after collection are mixed with the root stubbles, which is not conducive to the effective recycling and utilization of the plastic films. If the root stubbles are burned, it is easy to pollute the environment due to the mixture of plastic films; when in use, the plastic films are easily hung on the rod bodies of the drum sieve and block the sieve holes, and the cleaning process is time-consuming and laborious.

[0025] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other. The following will further describe the technical solutions of the present invention in conjunction with the drawings of the embodiments of the present invention. The present invention is not limited to the following specific implementation manners.

[0026] It should be understood that the same or similar reference numerals in the drawings of the embodiments correspond to the same or similar components. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc. indicating the orientation or positional relationship, they are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0027] In a specific implementation manner of the present invention, there is a residual film recycling machine for separating and compressing the residual film from the mixture of the residual film and soil, including: a frame, a soil-lifting device, a conveying device, a screening device, a traveling device, and a film-wrapping device.

[0028] The soil-lifting device is arranged at the front end of the frame, and the soil-lifting device can shovel up the plastic film and soil. The conveying device is arranged at the rear side of the soil-lifting device on the front side of the frame, and the conveying device can transport the plastic film and soil backward. The screening device is arranged on the frame at the rear side of the conveying device, and the screening device can rotate for preliminary screening of the soil and the residual film, and bring the residual film and part of the soil into the air and let them fall to form a film-collecting area. The traveling device is installed on the frame, so that the residual film recycling machine can be driven to move forward.

[0029] The film-wrapping device further includes: a wire-releasing mechanism, a film-wrapping wire, and a compression mechanism.

[0030] The wire unwinding mechanism is arranged on the front side of the screening device. The wire unwinding mechanism includes at least two wire reels. There are at least two winding films wires. One end of the winding film wire is wound around the wire reel, and the other end of the winding film wire is fixed. The winding film wire passes through the film collecting area and can separate and collect the residual film falling in the film collecting area from the soil. The compression mechanism is arranged on the rear side of the screening device. The winding film wire passes through the compression mechanism. The compression mechanism can twist multiple winding film wires together with the collected residual film into a thick rope. The junction of multiple winding film wires and the thick rope is the compression point. The compression point is arranged in the screening mechanism.

[0031] In a more preferred embodiment, the screening device adopts a shaftless cylindrical screen cylinder. The screen surface of the shaftless cylindrical screen cylinder is a wavy screen surface, which can generate secondary vibration with a small amplitude, thereby reducing the adhesion and blockage of viscous materials or fine particles. The shaftless cylindrical screen cylinder is installed on the frame at an angle of 1-20° to the horizontal plane. The shaftless cylindrical screen cylinder is rotated by a transmission component. The soil and residual film transported to the shaftless cylindrical screen cylinder by the conveying device are scattered during rotation due to the secondary vibration of the screen mesh. The scattered soil passes through the screen mesh and falls in the field. The shaftless cylindrical screen cylinder rotates, and the residual film is carried by the wavy screen to the top of the screening device and then falls onto the winding film wire.

[0032] In an even more preferred embodiment, the residual film recycling machine further includes a collection box. The collection box is arranged on the frame and cooperates with the rear side of the screening device. When part of the residual film is separated from the soil by the screening device and is not collected on the winding film wire, this part of the residual film is transported by the screening device into the collection box, further increasing the recovery rate of the residual film recycling machine for residual film.

[0033] Furthermore, the wire unwinding mechanism further includes a wire shaft and a bracket. The wire shaft is fixed on the bracket. The wire reel is rotatably connected to the wire shaft and has a tensioning component. The tensioning component provides a tensioning force for the wire reel.

[0034] Furthermore, the compression mechanism includes a mounting seat and a rope-twisting rocker arm. The rope-twisting rocker arm is rotatably mounted on the mounting seat. The winding film wire passes through the rope-twisting rocker arm. The rotation of the rope-twisting rocker arm can twist multiple winding film wires into a thick rope.

[0035] Furthermore, the rope-twisting rocker arm includes three parts: a rotating cylinder, a rocking handle, and a guiding ring. The rotating cylinder and the guiding ring are respectively arranged at both ends of the rocking handle. The rotating cylinder is rotatably connected to the mounting seat. The winding film wire passes through the rotating cylinder and the guiding ring. The rotation of the rope-twisting rocker arm around the axis of the rotating cylinder can twist multiple winding film wires into a thick rope.

[0036] Furthermore, the winding film device further includes a wire winding mechanism. The wire winding mechanism can rotate around an axis to pull out the winding film wire from the wire reel and wind up the thick rope. The wire winding mechanism can be any device with a winding function.

[0037] In a more preferred embodiment, the winding mechanism further includes a rotating shaft, a coil unloading assembly, and a latch-type mounting seat. The rotating shaft is rotatably mounted on the latch-type mounting seat, and the latch-type mounting seat can be opened to remove the rotating shaft. The coil unloading assembly is mounted on the rotating shaft, and the coil unloading assembly can tighten or loosen the thick rope collected on the coil unloading assembly. This kind of winding mechanism can conveniently disassemble the rope reel formed by the winding film line and the residual film wound on the coil unloading assembly.

[0038] Furthermore, the film winding device further includes a front-end wire control mechanism, which is arranged between the wire feeding mechanism and the screening device. The winding film line passes through the front-end wire control mechanism, and the front-end wire control mechanism can control the position of the winding film line. Under different working conditions, the size and position of the film collection area formed by the screening device bringing up the mixture of soil and residual film will change. According to the different film collection areas formed under different working conditions, the angle between the winding film lines can be adjusted so that the winding film lines are arranged at positions convenient for hanging the residual film.

[0039] In a preferred embodiment, the front-end wire control mechanism includes an L-shaped telescopic assembly and a wire control ring. The wire control ring is arranged on the L-shaped telescopic assembly, and the winding film line passes through the wire control ring. The L-shaped telescopic assembly can telescopically move up, down, left, and right along the L shape, so as to control the included angle between the winding film lines to change between 0° and 90°.

[0040] Furthermore, the film winding device includes a rear wire control mechanism, which is arranged between the screening device and the compression device. The thick rope passes through the rear wire control mechanism, and the rear wire control mechanism can control the movement of the compression point.

[0041] Furthermore, the film winding device further includes a driving component A for driving the compression mechanism to rotate around the axis and a driving component B for driving the winding mechanism to rotate around the axis. As Figure 1 Both the driving component A and the driving component B in are prime movers. Compared with driving through a transmission structure, the application of prime movers avoids the losses brought by the multi-stage transmission structure, and also avoids the problem of high failure rate of the multi-stage transmission structure in the harsh field operation environment of the residual film recycling machine.

[0042] In a preferred embodiment, a gathering device is further provided above the conveying device. The gathering device includes film gathering plates. The angle between the two film gathering plates is 1 - 15°. The distance between the two film gathering plates at the end close to the shaftless cylindrical screening device is smaller than the distance at the end close to the soil lifting device, and the distance between the two film gathering plates at the end close to the screening device is not greater than the diameter of the shaftless cylindrical screening device. When the mixture of residual film and soil enters the conveyor belt, the mixture is gathered by the two side film gathering plates during the backward conveyance of the conveyor belt and enters the screening device. The gathering device can prevent the conveyor belt from misdelivering the mixture of residual film and soil outside the screening device, thereby avoiding the problem of residual film remaining caused by misdelivery.

[0043] The following provides a preferred implementation process of the residual film recycling machine provided by the present invention. It should be noted that the actual implementation process of the technical solution adopted by the present invention is not limited to the following process.

[0044] When the residual film recycling machine is driven forward by a tractor, the soil lifting device can shovel up the residual film and soil. The residual film and soil shoveled up by the soil lifting device fall onto the conveying device arranged at the rear side of the soil lifting device on the front side of the frame. The transmission component D can cooperate to drive the conveying device to convey the soil and residual film shoveled up by the soil lifting device backward. During the conveyance, the film gathering plates arranged on the conveying device gather the mixture of residual film and soil. The mixture of residual film and soil is transported to the shaftless cylindrical sieve drum. The arranged film gathering plates prevent the residual film and soil from falling outside the shaftless cylindrical sieve drum, causing the problem of incomplete removal of field residual film. The transmission component E drives the shaftless cylindrical sieve drum to rotate. The sieve surface of the shaftless cylindrical sieve drum adopts a wavy sieve surface, which can generate a secondary vibration with a smaller amplitude, thereby reducing the adhesion and blockage of viscous materials or fine particles. The screening device is installed on the frame at an angle of 1 - 20° to the horizontal plane. The screening device is rotated by the transmission component E. The soil and residual film transported to the screening device are shaken loose during the rotation due to the secondary vibration of the sieve mesh. The shaken loose soil passes through the sieve mesh and falls onto the field. The screening device drives the wavy sieve mesh to rotate together, and the residual film is lifted by the wavy sieve mesh to the apex of the screening device and then falls.

[0045] The film wrapping device is arranged on the frame and passes through the screening device. The film wrapping wire reel on the wire drum of the wire pay-off mechanism is continuously pulled out by the wire winding mechanism. By adjusting the front-end wire control mechanism and the rear-end wire control mechanism, the angle between the film wrapping wires and the relative position of the compression point on the residual film recovery machine can be controlled, so that the residual film brought to the top of the screening device by the wave-type screen can fall more on the film wrapping wire, and the residual film will be hung on the film wrapping wire. The residual film hung on the film wrapping wire is twisted into a tight thick rope by the compression mechanism along with the film wrapping wire. The thick rope is finally coiled on the wire unloading assembly as the rotating wire unloading assembly is rotated. After the wire winding mechanism collects enough residual film, the rotating shaft is removed, and then the wire unloading assembly is contracted to loosen the coiled thick rope reel of the wire unloading assembly. The wire reel loses tension and can be easily separated axially from the unwinding assembly.

[0046] The residual film recovery machine also includes a collecting box, which is arranged on the frame and cooperates with the rear side of the screening device. When part of the residual film is separated from the soil by the screening device and is not collected on the film wrapping line, this part of the residual film is transported to the collecting box by the screening device, further increasing the recovery rate of the residual film by the residual film recovery machine.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
