Description

Technical Field

[0001] This utility model relates to the technical field of residual film recycling machines, specifically to a soil screening structure for a residual film recycling machine. Background Technology

[0002] The residual film recycling machine is an agricultural machinery device mainly used to clean and recycle residual plastic film in farmland. It is widely used in farmland, greenhouses and other places. In particular, in farmland, the use of residual film recycling machines can effectively solve the problem of residual plastic film, which is of great significance for improving farmland quality and protecting the ecological environment.

[0003] Currently, some residual film recycling machines are inconvenient to disassemble and assemble when using the screen cage, making quick installation difficult. During disassembly and assembly, users need to follow specific steps and sequences, which usually involves tightening and loosening multiple bolts, nuts, and other fasteners. This process is not only cumbersome but also prone to errors, increasing operational difficulty and time costs. Furthermore, some residual film recycling machines have two power sources for the conveying and screening components, which means that additional engines, motors, or other drive equipment are required. This increases the manufacturing cost of the equipment, and maintaining and servicing the two power sources also requires more time and resources, thereby increasing operating costs.

[0022] Please see Figure 1-5As shown, a soil screening structure for a residual film recycling machine includes a housing 1. A lower mounting frame 2 is bolted to one side of the bottom of the inner wall of the housing 1. A soil screening device 3 is installed above the lower mounting frame 2. A support frame 4 is bolted to one side of the inner wall of the housing 1, which helps to stabilize the soil screening device 3. An upper mounting frame 5 is installed on one side of the lower mounting frame 2. The inner diameters of the lower mounting frame 2 and the upper mounting frame 5 are equal. Positioning mechanisms 6 are installed on both sides of the lower mounting frame 2 and the upper mounting frame 5, which quickly connect the lower mounting frame 2 and the upper mounting frame 5. Spherical rollers 7 are rolledly connected to the inner walls of both the lower mounting frame 2 and the upper mounting frame 5. There are several spherical rollers 7, and the distance between them is equal. The spherical rollers 7 make it easier to rotate the soil screening device 3. Drive shafts 8 are rotatably connected to both sides of the inner wall of the housing 1. Transmission belts 9 are driven to the surface of the drive shafts 8 on both sides. A protective box 10 is bolted to one side of the surface of the housing 1 to prevent... A servo motor 11 is bolted to one side of the surface of the protective box 10. The output shaft of the servo motor 11 is bolted to the drive shaft 12. Under the action of the servo motor 11, the drive shaft 12 can rotate. A linkage mechanism 13 is set inside the protective box 10. When the drive shaft 12 rotates, the linkage mechanism 13 can run. The linkage mechanism 13 works in conjunction with the transmission shaft 8 on one side. When the linkage mechanism 13 runs, the transmission shaft 8 on one side can rotate. When the transmission shaft 8 on one side rotates, the conveyor belt 9 can rotate. When the conveyor belt 9 rotates, the soil and residual film on the surface of the conveyor belt 9 can be transported to the interior of the soil screener 3. A toothed disc 14 is bolted to the other end of the surface of the drive shaft 12. When the drive shaft 12 rotates, the toothed disc 14 can rotate. An external toothed ring 15 is bolted to one side of the surface of the soil screener 3. One side of the surface of the toothed disc 14 and one side of the surface of the external toothed ring 15 mesh with each other. When the toothed disc 14 rotates, the external toothed ring 15 can drive the soil screener 3 to rotate. When the soil screener 3 rotates, the soil can be screened.

[0023] The positioning mechanism 6 includes two mounting bases 61. One side of the surface of each mounting base 61 is bolted to one side of the surface of the lower mounting bracket 2. Insert plates 62, T-shaped designs, are bolted to both sides of the surface of the upper mounting bracket 5. Tension springs 64 are fixedly connected to both sides of the surface of each mounting base 61. Pull plates 63 are fixedly connected to the other end of the surfaces of the tension springs 64. The surface of the pull plate 63 is slidably connected to one side of the inner wall of the mounting base 61. When the pull plate 63 moves, it allows the two sides to slide together. When the tension spring 64 is stretched, it can release the obstruction of the inner wall of the mounting base 61 when the pull plate 63 moves to the appropriate position. Under this action, the insert plate 62 can be inserted into the inner wall of the mounting base 61. When the insert plate 62 is inserted into the inner wall of the mounting base 61, the pull plate 63 can quickly return to its original position under the action of the tension springs 64 on both sides. Under this action, the pull plate 63 can enter the inner cavity of the insert plate 62. The width of one side of the surface of the pull plate 63 is equal to the width of the inner cavity of the insert plate 62. Under this action, the insert plate 62 can be prevented from moving easily.

[0024] The linkage mechanism 13 includes a bevel gear 131. One inner wall of the bevel gear 131 is bolted to one side of the surface of the drive shaft 12. When the drive shaft 12 rotates, the bevel gear 131 rotates. A rotating shaft 132 is bolted to the inner wall of one side of the bevel gear 131. Pulleys 133 are rotatably connected to both sides of the inner wall of the protective box 10. The inner wall of one pulley 133 is bolted to one side of the surface of the rotating shaft 132. When the bevel gear 131 rotates, the rotating shaft 132 rotates. When 32 rotates, it can drive the pulley 133 on one side to rotate. A transmission belt 134 is connected to one side of the surface of the two pulleys 133. When the pulley 133 on one side rotates, the transmission belt 134 can rotate. A linkage rod 135 is bolted to the inner wall of the pulley 133 on the other side. One end of the surface of the linkage rod 135 is bolted to one end of the surface of the transmission shaft 8 on one side. When the pulley 133 on the other side rotates, the linkage rod 135 can rotate. When the linkage rod 135 rotates, the transmission shaft 8 on one side can rotate.

[0025] Working principle: When the soil sieve 3 needs to be installed, place the soil sieve 3 above the lower mounting frame 2 and the support frame 4, and then pull the two side pull plates 63. Next, the movement of the pull plates 63 will stretch the tension spring 64. When the pull plates 63 move to the appropriate position, remove the upper mounting frame 5, and then insert the two side insert plates 62 into the inner wall of the corresponding mounting base 61. Next, under the action of the tension spring 64, the pull plates 63 can quickly return to their original position and enter the inner cavity of the insert plates 62. This action can prevent the soil sieve 3 from falling. When it is necessary to screen the residual film and soil, turn on the servo motor 11. Under the action of the servo motor 11, the drive shaft 12 can rotate. When the drive shaft 12... When rotated, the bevel gear 131 rotates, which in turn causes the rotating shaft 132 to rotate. Next, the rotating shaft 132 rotates, causing the pulley 133 on one side to rotate. When the pulley 133 on one side rotates, the transmission belt 134 rotates. Then, the transmission belt 134 rotates, causing the pulley 133 on the other side to drive the linkage rod 135 to rotate. Next, the linkage rod 135 rotates, causing the transmission shaft 8 on one side to rotate. When the transmission shaft 8 on one side rotates, the transmission belt 9 runs. At the same time, when the drive shaft 12 rotates, the gear disc 14 rotates. Then, the gear disc 14 rotates, causing the outer gear ring 15 to rotate. The rotation of the outer gear ring 15 causes the soil screen 3 to rotate.
