Description

Technical Field

[0001] The present invention relates to the field of agricultural equipment, in particular to a household mulch film recycling machine. Background Art

[0002] In modern household farming, mulching is widely used to improve crop yield and quality. This practice is typically applied during the early stages of crop cultivation. Once the crops have emerged or matured, the mulch needs to be recovered. Otherwise, the mulch remaining in the soil can cause serious soil pollution, disrupt soil structure, and affect crop growth.

[0003] Publication (Announcement) No.: CN104322165B discloses a ground film recycling machine, including a main frame, digging teeth, a pull rod, a rocker, a picking tooth, a drive wheel, a chain, etc. The pull rod pulls the rocker to swing, thereby causing the digging teeth to swing, which can better dig out the broken ground film buried in the ground and shake off the soil. Subsequently, the ground film is transported backward through the cooperation of the picking teeth, the drive wheel, and the chain. The picking teeth of the above structure are fixedly installed, and the ground film is picked up as the chain rotates. However, since each row of picking teeth is arranged at equal intervals, if the digging teeth lift the ground film to the highest point and happen to be located between two adjacent picking teeth, as the digging teeth and the ground film fall back, the picking teeth cannot accurately hook and grab the ground film, affecting the accurate recovery of the ground film.

Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0024] like Figure 1 、 Figure 2 and Figure 3As shown, the household ground film recycling machine includes: a frame 1, a film lifting device 2, a picking device 3, a film transporting device 4, a reducer 5, a first transmission mechanism 6, a film collecting device 7, wheels 8 and a second transmission mechanism 9. The frame 1 is a frame structure made of metal or alloy material. As a supporting structure of the entire device, it has good strength. A traction arm is installed on the frame 1. The traction arm is installed on one side of the overall traction direction of the device and is used to connect to an external traction power device such as a tractor, so that the device can be towed to move as a whole. There are two wheels 8, which are symmetrically installed at the bottom end of the frame 1. The film lifting device 2 is installed at the bottom end of the frame 1. The film lifting device 2 interacts with the ground soil and can shovel up the ground film on the surface to facilitate subsequent ground film recovery work. The picking device 3 is installed on the frame 1 and is used to pick up the turned-up ground film. The film transporting device 4 is installed on the frame 1 and can transport the picked-up ground film and make the soil fall back to the ground. The film collecting device 7 is installed on the frame 1, and its position corresponds to that of the film transporting device 4. The film collecting device 7 is a box structure with an open top, and its width is adapted to the width of the film transporting device 4. The reducer 5 is installed on the frame 1. The reducer 5 is a spiral bevel gear steering box, which is the main power source of the equipment. Its input end is connected to the power output shaft of the external tractor. Specifically, a T10-1-1-LR-B3 spiral bevel gear steering box is adopted. The output end of the reducer 5 is perpendicular to the power input direction and has two mutually symmetrical power output shafts. The first transmission mechanism 6 is installed on one side of the frame 1, and is used to transmit the power of the reducer 5 to the film transporting device 4. The second transmission mechanism 9 is installed on the other side of the frame 1, and is used to transmit the power of the reducer 5 to the picking device 3.

[0025] refer to Figure 2 and Figure 5The film-lifting device 2 includes: a mounting frame 21, short film-lifting teeth 22, long film-lifting teeth 23 and a hydraulic cylinder 24. The mounting frame 21 is rotatably mounted on the bottom end of the frame 1. The hydraulic cylinder 24 is rotatably mounted on the frame 1, and the output end of the hydraulic cylinder 24 is rotatably mounted on the mounting frame 21. In actual use, a hydraulic oil barrel and a hydraulic pump are installed on the frame 1. The hydraulic pump can supply oil to the hydraulic cylinder 24 to achieve the extension and contraction of the hydraulic cylinder 24. In addition, the hydraulic cylinder 24 selected in this embodiment is a hydraulic cylinder with a self-locking output end, the model is JEAL-R circular mechanical self-locking oil cylinder, but it is not limited to this model, and other suitable models can be selected. There are two long film-lifting teeth 23, which are symmetrically mounted on both sides of the mounting frame 21. There are several short film-lifting teeth 22, which are equidistantly mounted on the mounting frame 21, and the short film-lifting teeth 22 are located between the two long film-lifting teeth 23. The short film-lifting teeth 22 and the long film-lifting teeth 23 are inclined from top to bottom in the forward direction of the equipment, and the inclination angle is the same. Before use, the short film-lifting teeth 22 and the long film-lifting teeth 23 have a small angle with the horizontal plane to ensure that they are in a retracted state. In actual use, the hydraulic cylinder 24 is turned on to rotate the mounting frame 21 and the short film-lifting teeth 22 and the long film-lifting teeth 23 together, so that the short film-lifting teeth 22 and the long film-lifting teeth 23 are in a state with an angle of 35° into the soil. At this time, the short film-lifting teeth 22 and the long film-lifting teeth 23 can be inserted into the soil to a depth of 40-70mm. In this embodiment, 50mm is taken as an example. As the equipment moves, the ground film can be turned over, and the film-lifting rate is 94.2%.

[0026] refer to Figure 4 、 Figure 5 、 Figure 7 and Figure 8The picking device 3 includes: a roller 31, a knife groove 3101, a rotating shaft 3102, an end cover 3103, a connecting frame 32, a rotating hole 3201, a cam groove 33, a swinging frame 34, a first roller 3401, a second roller 3402, and a picking tooth 35. The roller 31 is rotatably arranged in the frame 1. There are a plurality of knife grooves 3101, which are arranged in an array on the surface of the roller 31. There are two end covers 3103, each fixedly mounted on both sides of the frame 1. There are two connecting frames 32, each fixedly mounted on the inner side of the roller 31 at both ends. There are six rotating holes 3201, each equidistantly mounted along the circumferential direction on the side of the connecting frame 32 close to the inner wall of the roller 31. The two ends of the rotating shaft 3102 pass through the center positions of the two connecting frames 32, and the two are fixedly mounted. The two ends of the rotating shaft 3102 are rotatably mounted on the frame 1 and rotate through the center positions of the two end covers 3103. The cam groove 33 is provided on the side of the end cover 3103 facing the inner cavity of the drum 31. The cam groove 33 has a different diameter closed structure, including: a distal groove 3301, a first transition groove 3302, a proximal groove 3303 and a second transition groove 3304. The distal groove 3301 is arranged in an arc shape, and its center is coaxial with the end cover 3103. The proximal groove 3303 is a straight groove, and its maximum distance from the center of the end cover 3103 is less than the distance between the distal groove 3301 and the center of the end cover 3103. The two ends of the distal groove 3301 are respectively connected to the two ends of the proximal groove 3303 through the first transition groove 3302 and the second transition groove 3304. The first transition groove 3302 and the second transition groove 3304 are arranged in an arc shape to ensure smooth transition. There are six swing frames 34 installed in the drum 31 at equal distances along the circumference. The swing frame 34 is a rectangular frame structure. There are two first rollers 3401, symmetrically mounted at either end of one long side of the swing frame 34. The two first rollers 3401 rotate through the rotating hole 3201. There are two second rollers 3402, symmetrically mounted at either end of the other long side of the swing frame 34. The two second rollers 3402 slide in the two cam slots 33. There are a number of picking teeth 35, equidistantly mounted on the long side of the swing frame 34 where the second rollers 3402 are mounted. The picking teeth 35 are curved, with the curvature aligning with the rotation direction of the drum 31, to facilitate picking up ground film.

[0027] The working principle of the above structure in actual use is as follows: when the rotating shaft 3102 is controlled to rotate, the roller 31 and the connecting frame 32 will rotate synchronously. Initially, the rotating hole 3201 drives the first roller 3401 to rotate. At this time, the second roller 3402 slides in the telecentric groove 3301, and the picking teeth 35 stably extend through the knife groove 3101 and rotate with the roller 31 to scoop up the ground film. Then continue to rotate, the rotating hole 3201 will drive the first roller 3401 to rotate together, and the second roller 3402 will slide in the cam groove 33. The limit of the cam groove 33 will cause each swing frame 34 to swing in the roller 31. Reference Figure 4 When the rotary hole 3201 rotates counterclockwise until it approaches the film transport device 4, the second roller 3402 slides into the second transition groove 3304 via the distal groove 3301. As the drum 31 and the connecting frame 32 continue to rotate, the rotary hole 3201 continues to rotate counterclockwise, and the second roller 3402 slides into the proximal groove 3303 via the second transition groove 3304. The swing frame 34 swings, causing the picking teeth 35 to retract into the drum 31. At this point, the ground film is hooked by the film transport device 4, achieving directional transport. The drum 31, the connecting frame 32, and the rotary hole 3201 continue to rotate, and the second roller 3402 returns to the distal groove 3301 via the proximal groove 3303 and the first transition section 3302. The picking teeth 35 extend again through the knife groove 3101, scooping up the ground film that was turned over by the film lifting device 2 and transferring it to the film transport device 4. In this way, the roller 31 rotates one circle to complete the expansion and contraction of the picking teeth 35 relative to the knife groove 3101, ensuring that the ground film can be inserted into the ground surface and scooped up when picking up the ground film. Then, the picking and transportation are completed, and the ground film is transported in a direction by the film transport device 4. This structure can directly insert into the soil surface to complete the picking of the ground film. The previous work only requires the film lifting device 2 to turn the ground film out of the soil. The expansion and contraction of the picking teeth 35 ensures that the ground film can be picked up accurately without being disturbed by other factors.

[0028] refer to Figure 2 In this embodiment, a second transmission shaft 502 is mounted on one output end of the speed reducer 5. The second transmission mechanism 9 includes a third pulley 91, a fourth pulley 92, and a second belt 93. The third pulley 91 is rotatably mounted on the frame 1 and is connected to the second transmission shaft 502. The fourth pulley 92 is rotatably mounted on the frame and is connected to the rotating shaft 3102. The second belt 93 is sleeved onto the third pulley 91 and the fourth pulley 92. After the speed reducer 5 is started, the picking device 3 begins to operate through power transmission from the second transmission shaft 502 and the second transmission mechanism 9.

[0029] refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 6The film transport device 4 comprises a sprocket roller 41, a chain 42, spikes 43, protruding studs 44, and a mounting plate 45. Two sprocket rollers 41 are rotatably mounted on the frame 1, with the axis connecting the two sprocket rollers 41 tilted 45 degrees. Sprockets are installed at each end of the sprocket rollers 41. Two chains 42 are respectively connected to two sets of sprockets on either side of the sprocket rollers 41 and mesh with the sprockets, ensuring that the chains are tensioned and rotated stably without skipping. Several mounting plates 45 are equidistantly mounted on the two chains 42, with gaps between adjacent mounting plates 45. In this embodiment, the chain transmission synchronizes the two sprockets, ensuring stable operation of the mounting plates 45. Several spikes 43 are equidistantly mounted on the surface of each mounting plate 45. The spikes 43 are curved in a direction opposite to the direction of sprocket rotation. The protruding studs 44 are mounted on the side of the spikes 43 facing the direction of sprocket rotation. When the picking device 3 delivers the ground film to the chain plate 42, the raised nails 44 are able to hook the ground film, and the thin-sheet nail teeth 43 are used to pull the ground film toward the film collecting device 7. At the same time, because the ground film is hooked, soil clods and other debris fall through the gap between the two connected nail teeth 43, and finally fall back to the ground through the gap between the two adjacent mounting plates 45.

[0030] In addition, in this embodiment, an arc-shaped guide plate 701 is installed at the top of the side opposite to the film collecting device 7 and the film transporting device 4. A number of through grooves 702 are evenly installed on the guide plate 701, and the several through grooves 702 correspond to the several spike teeth 43, thereby ensuring that the spike teeth 43 pass through the through grooves 702 smoothly and the ground film is separated, thereby allowing the ground film to enter the inner cavity of the film collecting device 7.

[0031] refer to Figure 2 In this embodiment, a first transmission shaft 501 is installed at the other output end of the reducer 5. The first transmission mechanism 6 includes: a first pulley 61, a second pulley 62 and a first belt 63. The first pulley 61 is rotatably mounted on the frame 1 and is connected to the first transmission shaft 501. The second pulley 62 is rotatably mounted on the frame and is connected to the sprocket roller 41 at the bottom end. The first belt 63 is sleeved on the first pulley 61 and the second pulley 62. After the reducer 5 is started, the film transport device 4 starts to operate through the power transmission of the first transmission shaft 501 and the first transmission mechanism 6.
