Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a farm machine for collecting film from cultivated land. Background Art

[0002] Agricultural machinery refers to various machines used in the production process of crop planting and animal husbandry, as well as in the primary processing and treatment of agricultural and livestock products. The film collecting machine is a machine for cleaning and recycling residual film in farmland. It is composed of film lifting, conveying, film separation, film collection, and film unloading mechanisms, and is towed by a tractor. According to the film lifting parts, it is divided into shovel-type and comb-tooth type. When working, the former uses a film lifting shovel to scoop up the topsoil and stubble containing the film, and sends it to the separation drum to screen the soil and separate the stubble, and accumulate the residual film; the latter uses comb teeth to loosen the soil and hug the film, and the picker with a telescopic rod picks up the film and separates the soil. The residual film is rolled up by the film rolling roller, and the film unloading device unloads the film to complete the operation.

[0003] In order to clean up the plastic film remaining on the cultivated land, it is necessary to recycle the plastic film through a film collector. When the traditional film collector is collecting the film, the plastic film will accumulate inside the agricultural machinery. When the film collector is running, the accumulated plastic film inside the film collector needs to be processed regularly. The common processing method is that the agricultural machinery needs to stop running, and then the plastic film is separated from the inside of the agricultural machinery manually. The separation operation is tedious and complicated, and often takes a lot of time. The plastic film is then placed on the cultivated land. After the overall film collection operation of the cultivated land is completed, the plastic film placed on the cultivated land is uniformly recycled. This type of equipment needs to clean the plastic film after running for a period of time, which greatly reduces the efficiency of film collection of cultivated land. This problem is particularly obvious when there is more plastic film in the cultivated land.

[0004] Based on this, an agricultural machine for collecting film on cultivated land is proposed. Summary of the invention

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 6 , the present invention provides a technical solution:

[0028] A farm machine for collecting plastic film on cultivated land comprises a bucket 1, which is rotatably connected to a support wheel 2, which needs to move along the drainage ditch between the fields of cultivated land, a guide frame 5 is connected to the outside of the bucket 1, and a guide wheel 6 is rotatably connected to the guide frame 5, and the guide wheel 6 moves on the cultivated land, a fixed sleeve 10 is connected to the outside of the bucket 1, and a motor 9 is fixedly connected to the fixed sleeve 10, and the firmness of the structural connection of the motor 9 is ensured by setting the fixed sleeve 10, and the output end of the motor 9 passes through the bucket 1 and is connected to a recovery roller 7, and the recovery roller 7 rotates clockwise, and an interpenetrating needle 8 is connected to the outside of the recovery roller 7, and the soil is broken up by the interpenetrating needle 8, so as to facilitate the separation between the plastic film and the soil, a lower bin 17 is provided in the bucket 1, and the lower surface of the lower bin 17 is in an inclined downward state, so that the broken soil can move along the lower bin 17 conveniently, and an interception fence 18 is connected to the lower bin 17, and the interception fence 18 has a certain screening effect, and only soil meeting the particle size requirements will pass through the interception fence 18, and a small part of the soil can also be intercepted The bucket 1 is connected with a conveying plate 11, which is connected to the upper end of the bucket 1, and the conveying plate 11 is arranged just above the unloading bin 17. A limiting structure is arranged on the left and right sides of the conveying plate 11 to prevent the plastic film from falling from the left and right sides of the conveying plate 11. A removing tooth 22 is connected to one side of the conveying plate 11, and the removing tooth 22 can separate the plastic wound on the recovery roller 7 from it, so that the plastic film enters the conveying plate 11. A slide groove 23 is provided on the conveying plate 11, and a side plate 16 is connected to the lower end of the conveying plate 11. A baffle 15 is slidably connected to the conveying plate 11. The baffle 15 structure intercepts the plastic film on the conveying plate 11 to prevent the plastic films from dragging each other and being unable to be effectively separated. The accumulated plastic film can be better separated by blocking the baffle 15. A lifting rod 20 is connected to the lower end of the baffle 15, and a discharging mechanism for discharging the recovered plastic film into the cultivated land is connected to the side plate 16 to prevent the plastic film from accumulating on the film collecting agricultural machine.

[0029] Specifically, Figure 1As shown, the outer side of the bucket 1 is rotatably connected to a traction frame 3, and the traction frame 3 is connected to a connecting buckle 4. When the film collecting agricultural machine is in operation, it needs to be towed and moved by a tractor, wherein the tractor and the traction frame 3 are connected to each other. The use of the connecting buckle 4 improves the convenience of connecting the film collecting agricultural machine to the tractor.

[0030] Specifically, Figure 2 As shown, a deflection frame 12 is rotatably connected to the outer side of the bucket 1, and a deflection plate 14 and a leveling comb 13 are connected to the deflection frame 12. The leveling comb 13 can comb the cultivated land to intercept the plastic film. The leveling comb 13 is lifted in conjunction with the deflection frame 12, so that the plastic film is piled on the cultivated land, which is convenient for subsequent recycling.

[0031] Specifically, Figure 3 As shown, a limit strip 25 is connected to the conveying plate 11, and the left and right ends of the baffle 15 are slidably connected to the limit strip 25. The lifting rod 20 is connected to the conveying plate 11 through the limit strip 25. The baffle 15 is limited by setting the limit strip 25 to improve the stability of the baffle 15 structure when lifting and lowering.

[0032] Specifically, Figure 5 and Figure 6 As shown, the unloading mechanism includes a toggle rod 24, through which the toggle rod 24 can achieve the effect of toggling the plastic film, thereby toggling the plastic films on the conveying plate 11 to separate from each other, and the plastic films are disconnected by pulling, thereby completing partial unloading of the plastic film on the conveying plate 11, and the remaining part continues to accumulate on the conveying plate 11, waiting for the next separation and unloading of the plastic film. Since the moving speed of the toggle rod 24 is greater than the speed at which the plastic accumulates on the conveying plate 11, the movement of the toggle rod 24 can easily achieve the disconnection between the plastic films. The toggle rod 24 is slidably connected between the side plates 16, and a lifting bar 30 is slidably connected to the side plates 16. One end of the lifting bar 30 is connected to a support sheet 31, and the support sheet 31 is arranged directly below the lifting bar 20. The lifting bar 30 is slidably connected to a connecting rod 21, and the connecting rod 21 is connected to A connecting block 32 is connected, and a toggle rod 24 is rotatably connected to the connecting block 32. A shaft is connected to the connecting block 32, and the lower end of the toggle rod 24 is rotatably connected to the shaft, wherein a structure for limiting the toggle rod 24 is provided on one side of the connecting block 32, so that the toggle rod 24 can only be deflected from a vertical state to a side away from the bucket 1, and a torsion spring 36 is connected at the connection between the toggle rod 24 and the connecting block 32. The torsion spring 36 has the effect of driving the toggle rod 24 to deflect to a vertical state, and bending frames 35 are connected to both ends of the connecting rod 21, and a bending groove 26 is provided on the side plate 16, and one end of the bending frame 35 is slidably connected to the bending groove 26, and one end of the bending frame 35 is rotatably connected to the cylinder 19, and the cylinder 19 is rotatably connected to the outer side of the conveying plate 11, and the bending frame 35 can be driven to slide on the bending groove 26 by the extension and contraction of the cylinder 19.

[0033] Specifically, Figure 5 As shown, a lifting rail 29 is connected to the side panel 16, and a clamping block 33 is slidably connected to the lifting rail 29. The clamping block 33 is fixedly connected to one side of the lifting bar 30. By setting the lifting rail 29 and the clamping block 33 to cooperate with each other, the lifting bar 30 can be stably slid and lifted on one side of the side panel 16.

[0034] Specifically, Figure 6 As shown, a slider 34 is slidably connected to the lifting bar 30, and two sliders 34 are provided. Both ends of the connecting rod 21 are connected between the sliders 34, and one end of the bending frame 35 is connected to the slider 34. By setting the slider 34 structure, the two ends of the connecting rod 21 are always in a mutually perpendicular state with the lifting bar 30.

[0035] Specifically, Figure 5 As shown, a rotating sleeve 27 is fixedly connected to the outside of the cylinder 19, a rotating shaft 28 is fixedly connected to the outside of the rotating sleeve 27, the rotating shaft 28 is rotatably connected to the conveying plate 11, and the telescopic end of the cylinder 19 is rotatably connected to the bending frame 35. When the cylinder 19 is extended and retracted, the cylinder 19 structure will deflect at the same time.

[0036] To sum up, the agricultural machine for collecting plastic film on cultivated land provided in the present embodiment can be towed by a tractor when the residual plastic film on the cultivated land needs to be recovered. The tail end of one end of the tractor needs to be connected to the connecting buckle 4, and the traction frame 3 is towed by the tractor to move the agricultural machine on the cultivated land. A scooping structure is connected to one side of the lower surface of the bucket 1. Scooping structures of different sizes can be used according to the different depths of drainage ditches between fields, so that the agricultural machine can adapt to cultivated land of different heights for operation.

[0037] When collecting the film, the operator needs to start the motor 9 and the cylinder 19 structure, wherein the motor 9 will drive the recovery roller 7 to rotate continuously when running, and the rotation direction is opposite to the direction in which the soil enters the bucket 1, that is, the recovery roller 7 rotates clockwise, and the support wheel 2 and the guide wheel 6 rotate counterclockwise, and the operation state of the cylinder 19 structure is intermittent telescopic, and the telescopic action is completed quickly. The intermittent time between the telescopic actions is related to the rotation speed of the recovery roller 7, that is, the faster the rotation speed of the recovery roller 7, the shorter the intermittent time of the cylinder 19, and its intermittent time is also related to the mass of the residual plastic film per square meter of the cultivated land. The greater the mass, the shorter the intermittent time of the cylinder 19.

[0038] When the film collecting agricultural machine moves on the cultivated land, the supporting wheel 2 moves on the drainage ditch of the cultivated land, and the guide wheel 6 makes it move on the cultivated land. When moving, the soil with the plastic film will enter the bucket 1, and the insertion needle 8 can pick the plastic film out of the soil and have the effect of breaking up the soil to a certain extent. The film collecting operation is performed in a dry soil state by default. The soil in a wet state is not conducive to the film collecting operation. The plastic film inserted on the insertion needle 8 will flip with the recovery roller 7. When the plastic film flips and contacts the removal teeth 22, the removal teeth 22 can remove the plastic film wrapped around the recovery roller 7, so that the plastic film is separated from the recovery roller 7. The surface of the removal teeth 22 close to the side of the recovery roller 7 is arc-shaped, and the arc-shaped surface is close to the outer side of the recovery roller 7 but does not abut. This structure improves the separation The efficiency is high. As the recovery roller 7 rotates continuously, a large amount of plastic film can be transported to the conveying plate 11. Therefore, the plastic film separated from the soil will accumulate on the conveying plate 11, and the accumulated plastic will move along the conveying plate 11 toward the baffle 15, and the soil separated from the plastic film will enter the bucket 1, and the soil will be further filtered by the interception fence 18. Only soil with small particle size will pass through the interception fence 18, wherein the interception fence 18 itself can also intercept a part of the plastic film. Since most of the plastic film has been driven to move and be recycled by the insertion needle 8, only a small part of the plastic film will enter the interception fence 18, and the soil that passes through the interception fence 18 will fall back on the cultivated land along the slope of the lower silo 17, and the soil that does not pass through the interception fence 18 will continue to be broken up by the insertion needle 8 until it meets the particle size requirements.

[0039] When a certain amount of plastic film remains on the conveying plate 11, the intermittent time of the cylinder 19 ends, and the cylinder 19 starts to retract from the maximum extension distance, and the cylinder 19 is used to pull the bending frame 35 to slide on the bending groove 26, wherein the bending groove 26 is composed of a three-section structure, including a vertical part, an inclined part and a horizontal part, and the inclined part is connected between the vertical part and the horizontal part. First, the bending frame 35 starts to slide in the horizontal part of the bending groove 26. At this time, the height of the lifting bar 30 remains unchanged, and the connecting rod 21 structure moves away from the bucket 1. When the toggle rod 24 moves to the upper end and contacts one end of the slide groove 23, as the connecting rod 21 continues to move, the toggle rod 24 changes from the deflected state to the vertical state, until the connecting block 32 moves with the connecting rod 21 to just below one end of the slide groove 23, at which time the toggle rod 24 is completely in the vertical state. At this time, the toggle rod 24 is limited by one side of the connecting block 32 and cannot continue to deflect. The toggle rod 24 is deflected to the vertical state by the torsion spring 36, and at this time, one end of the toggle rod 24 extends out of the plane of the conveying plate 11;

[0040] When the bending frame 35 slides to the inclined part of the bending groove 26, at this time, as the bending frame 35 moves, the toggle rod 24 rises in height and moves toward the baffle 15 at the same time, which has the effect of pushing the plastic film accumulated on the conveying plate 11 toward the baffle 15. When the toggle rod 24 rises in height, it can drive the support piece 31 at one end of the lifting bar 30 to push the lifting rod 20 to rise in height. At this time, the baffle 15 rises in height, which facilitates the movement of the plastic film under the push of the toggle rod 24. With the opening of the baffle 15, the accumulated plastic film falls down, and the accumulated plastic film moves with the agricultural machine. The flat comb 13 limits the plastic film again. At this time, the plastic film is located on the soil surface, which is convenient for recycling.

[0041] When the bending frame 35 slides to the vertical part of the bending groove 26, the toggle rod 24 rises in height, but does not continue to push the plastic film to fall from the conveying plate 11. At this time, the support plate 31 continues to rise in height, pushing the baffle plate 15 to rise in height, and the baffle plate 15 is used to push the deflection plate 14 to rise in height. At this time, the deflection frame 12 deflects, and the lower end of the leveling comb 13 leaves the ground. The plastic limited by the leveling comb 13 will be separated from the agricultural machinery structure as the leveling comb 13 is lifted. At this time, the piles of plastic film will stay on the cultivated land, and the lowering of the plastic film will be completed. The material operation can be carried out to avoid a large amount of plastic film accumulating on the conveying plate 11 to interfere with the continuation of the operation. The equipment can continuously recycle the plastic on the cultivated land without stopping the equipment to manually or mechanically clean the accumulated plastic film. After one cleaning is completed, the cylinder 19 structure begins to extend, the baffle 15 is reset, and the plastic film on the conveying plate 11 is limited again until the cylinder 19 extends to the maximum distance. At this time, one end of the bending frame 35 abuts against one end of the horizontal part of the bending groove 26. The equipment can improve the recycling efficiency of the plastic film on the cultivated land.
