Description
Technical Field
[0001] This utility model relates to the field of degradable mulch film covering technology, specifically a machine for covering and removing impurities from degradable mulch film. Background Technology
[0002] In agricultural production, biodegradable mulch film is widely used in crop planting due to its natural degradation and ability to reduce environmental pollution. Covering the crops with mulch film can effectively retain moisture, increase temperature, and suppress weed growth, thereby increasing crop yield. However, before the application of biodegradable mulch film, there are often impurities such as small stones, dead branches and leaves on the surface of the planting ridges. During the mulching process, due to the special nature of the material, the mulch film is easily torn by these impurities (such as small stones and dead branches and leaves from the previous crop). The degradation cycle of the biodegradable mulch film will be greatly accelerated after being torn, thus shortening the mulching time in the early stage of crop growth and failing to achieve the desired effect of biodegradable mulch film. Currently, traditional mulching operations mostly rely on manual cleaning of impurities before mulching, which is not only labor-intensive and inefficient, but also produces inconsistent cleaning results, making it difficult to meet the needs of large-scale planting. Although some existing mulching equipment integrates simple cleaning functions, it has the following shortcomings: The cleaning mechanism has a fixed height and cannot be flexibly adjusted according to the height of different planting ridges. It has poor adaptability to ridges of varying heights and is prone to either missing or over-cleaning. Therefore, it is necessary to design a machine for applying and removing biodegradable mulch film to solve the above problems. Utility Model Content

[0018] The movable platform 24 is slidably connected to the inside of the frame 1. The first limiting frame 27 is fixedly connected to the front and rear sides of the top of the movable platform 24. The first limiting frame 27 is slidably connected to the inside of the load-bearing frame 21.

[0019] The rotating rod 29 is rotatably connected inside the movable table 24. The bottom of the vibrating screen 292 is flush with the bottom of the cleaning brush 291, so that the cleaning brush 291 can be rotated by the rotating rod 29.
[0020] The cleaning brush 291 is made of nylon and is located at the left end of the frame 1. The vibrating screen 292 has screen holes inside. The frame 1 is made of high-strength steel, which makes it easy to separate small stones and larger impurities through the vibrating screen 292.
[0021] The protective cover 25 is located around the servo motor 28. The servo motor 28 and the vibrator 293 are electrically connected to the generator 4, which facilitates the protection of the servo motor 28 through the protective cover 25.
[0022] Example 2 Please see Figure 1-6 Furthermore, based on Embodiment 1, the film coating mechanism 3 further includes a fixed frame 31, which is fixedly connected to the top of the frame 1. A second hydraulic cylinder 32 is fixedly connected to the top of the fixed frame 31, and a fixed platform 34 is fixedly connected to the bottom of the second hydraulic cylinder 32. A second limiting frame 33 is fixedly connected to the front and rear sides of the top of the fixed platform 34. The second limiting frame 33 is slidably connected to the inside of the fixed frame 31. A support frame 35 is fixedly connected to the right side of the fixed platform 34.

[0023] The fixed platform 34, the support frame 35 and the film roller 39 are slidably connected inside the frame 1. The limiting shaft 36 passes through the support frame 35. Two sets of extension arms 38, limiting shaft 36 and fixing rod 37 are provided and symmetrically distributed on the front and rear sides of the support frame 35. The film roller 39 is made of wear-resistant steel. By setting two sets, film rollers 39 of different sizes can be fixed, which improves convenience.
[0024] In actual operation, when this device is used, when it is necessary to cover the top of the planting ridge with film, the frame 1 is first moved to the designated position by the action of the moving wheels 6 and the handle 5, and the moving wheels 6 are placed on the front and rear sides of the ridge, so that the cleaning brush 291 and the vibrating screen 292 are located at the top of the ridge. At this time, according to the height of the ridge, the moving platform 24 is moved by the first hydraulic cylinder 22, and the moving platform 24 drives the first limit frame 27 to slide inside the load-bearing frame 21. The height of the cleaning brush 291 and the vibrating screen 292 can be adjusted according to the height of the planting ridge, so that they are located at the top of the ridge. At the same time, remove the limiting shaft 36, place the film roller 39 inside the two sets of fixing rods 37, and according to the size of the film roller 39, make the extension arm 38 slide inside the support frame 35, so that the two sets of fixing rods 37 move the same distance and slide into the hole inside the film roller 39. At the same time, fix the extension arm 38 through the limiting shaft 36 to ensure the stability between the extension arm 38 and the support frame 35. Then the film roller 39 can be installed, and one end of the film is fixed at the beginning of the ridge. Workers move the frame 1 using the handrail 5 and the casters 6. During the movement, the servo motor 28 drives the rotating rod 29 to rotate the cleaning brush 291, which can efficiently sweep away small stones and dead leaves. The swept impurities will enter the vibrating screen 292. The vibrator 293 drives the vibrating screen 292 to vibrate, which can further screen the impurities, separating small stones and larger impurities, and screening them out of the vibrating screen 292 through the screen holes. Larger impurities will remain inside the vibrating screen 292. The left side of the vibrating screen 292 is open to facilitate the cleaning of impurities. The nylon cleaning brush 291 not only has a good cleaning effect, but also improves its service life. The dual function greatly improves the thoroughness of impurity removal, providing a clean basic environment for subsequent film coating operations. During the cleaning process, the height of the fixed platform 34 can be adjusted by the second hydraulic cylinder 32, so that the fixed platform 34 drives the second limiting frame 33 to slide inside the fixed frame 31, thereby adjusting the height of the film roller 39. It can adapt to different film covering needs and ground conditions according to the height of different ridges. The two sets of symmetrically distributed extension arms 38, limiting shafts 36 and fixing rods 37 enhance the stability of the film roller 39 installation and ensure the continuity of the film covering process. Furthermore, during the relocation process, the cleaned ridges can be covered with plastic film, effectively reducing the breakage rate of degradable plastic film during mulching. The load-bearing frame 21 is slidably connected to the top of the frame 1 and fixed by the fixed shaft 23, which not only facilitates installation and disassembly, but also allows it to be installed at the front end of other laminating machines, improving its applicability. Furthermore, the right side of the protective cover 25 is provided with heat dissipation holes and wiring slots, which are rectangular and circular, respectively, to facilitate heat dissipation and wiring of the servo motor 28. The frame 1 is made of high-strength steel, which makes it sturdy and durable. It can adapt to complex field operation environments and extend the service life of the equipment. The servo motor 28, vibrator 293 and generator 4 are electrically connected to ensure the stability of the power supply of each component. It does not need to rely on external power supply and improves the applicability of the machine in field operations.
