Technical Field

[0001] The utility model relates to the technical field of agricultural mulch film laying, in particular to a degradable mulch film laying device for suppressing weeds and preventing insects in cherry orchards. Background Art

[0002] Cherry orchards need to control weeds and insects because weeds will compete with cherry trees for nutrients and water, affecting ventilation and light transmission as well as orchard management; pests will directly harm the health of cherry trees, resulting in a decline in cherry quality and reduced yield, and pests can also spread diseases. These factors combined will have a serious negative impact on the yield, quality and long-term growth of cherry trees in the cherry orchard.

[0003] A mulch film laying device is used to control weeds and prevent insects in cherry orchards. The working principle of the mulch film laying device is to unfold the mulch film by rotating the reel under pulling, use the guide mechanism to ensure the accurate unfolding of the mulch film, use stones to bury the edge of the mulch film into the soil to fix it, and then use the film pressing mechanism (such as the film pressing wheel) to make the mulch film fit tightly to the ground. The movements of each component must cooperate with each other to ensure the smooth, accurate and high-quality laying of the mulch film.

[0031] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3The present invention provides an embodiment of a degradable ground film laying device for weed and insect control in cherry orchards, comprising a support frame 1. The support frame 1 is the basic structure of the entire device, providing a platform for mounting and supporting other components. The support frame 1 has two placement slots 2 defined within it, with a fixed plate 3 slidably connected to the inner wall of the placement slot 2. The placement slot 2 is located within the support frame 1, and its inner wall is slidably connected to the fixed plate 3. This sliding connection allows the fixed plate 3 to slide freely within the placement slot 2, thereby adjusting its position.

[0033] The fixed plate 3 is internally slidably connected to a pressure rod 4, which serves to connect and fix other components in the device. The internal sliding connection is connected to a pressure rod 4, and this sliding connection design allows the pressure rod 4 to move up and down smoothly inside the fixed plate 3. The top of the pressure rod 4 is fixedly connected to a pressure block 5, which is an important component for force transmission. The top is fixedly connected to a pressure block 5, and by pressing the pressure block 5, the operator transmits pressure downward along the pressure rod 4. The external sliding connection of the pressure rod 4 is connected to an extrusion column 6, and the pressure block 5 is the part where the operator directly applies force.

[0034] It is fixedly connected to the top of the pressure rod 4. When the operator presses the pressure block 5, the pressure block 5 transmits the external force to the pressure rod 4, causing the pressure rod 4 to move inside the fixed plate 3 and the extrusion column 6, thereby starting the fixing operation of the entire device. The extrusion column 6 has two chute grooves 7 inside, and the pressure rod 4 is externally rotatably connected to two rotating rods 8. The extrusion column 6 is a key component for fixing the device in the ground. It has two chute grooves 7 inside for cooperating with the rotating rod 8. During operation, the extrusion column 6 passes through the membrane cloth and is inserted into the ground. When the pressure rod 4 moves downward under pressure, it pushes the extrusion column 6 further into the ground.

[0035] The outside of the pressure rod 4 is provided with an elastic component that can provide elastic force to the rotating rod 8. The elastic component includes an inner sleeve 9, one side of which is fixedly connected to the outside of the pressure rod 4. The inner sleeve 9 is fixedly connected to the outside of the pressure rod 4, providing a fixed installation position for spring 11 and cooperating with the outer sleeve 10, allowing spring 11 to extend and retract between the two. The side of the rotating rod 8 close to the pressure rod 4 is fixedly connected to the outer sleeve 10, and the interior of the inner sleeve 9 is fixedly connected to the spring 11. The rotating rod 8 plays a key role in fixing and unlocking the device.

[0036] An outer sleeve 10 is fixedly connected to the side near the pressure rod 4, forming an elastic assembly with the inner sleeve 9 and spring 11 on the pressure rod 4. The end of spring 11 away from the inner sleeve 9 is fixedly connected to the inside of the outer sleeve 10. When the extrusion column 6 is inserted into the ground, spring 11 is stretched, generating a pulling force on the rotating rod 8, causing the rotating rod 8 to expand to both sides and be fixed in the chute 7, thereby fixing the extrusion column 6. When the extrusion column 6 needs to be pulled out, the rotating rod 8 is pressed inward, and spring 11 is compressed, providing space for the rotating rod 8 to move. The outer part of the rotating rod 8 is slidably connected to the inner wall of the chute 7. The chute 7 is located inside the extrusion column 6 and its main function is to provide a track for the rotating rod 8 to move. The outer part of the inner sleeve 9 is slidably connected to the inside of the outer sleeve 10, cooperating with the inner sleeve 9 to form a space for spring 11.

[0037] Reference Figure 4 Two adjustment components are provided inside the support frame 1 to adjust the flatness of the membrane cloth. The adjustment components include a sliding column 12. The outer portion of the sliding column 12 is slidably connected to the inner portion of the support frame 1. The top of the sliding column 12 is fixedly connected to a limit plate 13 to limit the sliding column 12. A spring 14 is sleeved on the outer portion of the sliding column 12. A pressure wheel 15 is fixedly connected to the side of the sliding column 12 away from the limit plate 13, allowing it to move up and down within the support frame 1.

[0038] The top of the sliding column 12 is fixedly connected to the limiting plate 13, and the bottom is fixedly connected to the pressure wheel 15. During the movement of the device, when the pressure wheel 15 is subjected to force due to changes in the ground height, the sliding column 12 will slide up and down accordingly in the support frame 1, thereby ensuring that the pressure wheel 15 can adapt to changes in the ground height. One end of the spring 2 14 is fixedly connected to the outside of the sliding column 12, and the other end of the spring 2 14 is fixedly connected to the outside of the pressure wheel 15. When the pressure wheel 15 squeezes the sliding column 12 upward due to changes in the ground height, the spring 2 14 is compressed, and the reaction force generated will make the pressure wheel 15 contact the membrane cloth more closely, thereby ensuring the flatness of the contact between the membrane cloth and the ground, and improving the quality of the ground film laying.

[0039] During the movement of the device, the pressure wheel 15 is in contact with the membrane cloth. Due to the different ground heights, the pressure wheel 15 will be squeezed upward to varying degrees. Through the cooperation of the sliding column 12 and the spring 2 14, the pressure wheel 15 can always be in close contact with the membrane cloth, ensuring the flatness of the membrane cloth during laying, and can adapt to the changes in different terrains in the cherry orchard, making the ground film laying more uniform and flat. Two mounting components are provided on the outside of the support frame 1. The mounting components can adapt to different ground heights for laying. The mounting components include a connecting rod 16. One side of the connecting rod 16 is fixedly connected to the outside of the side of the support frame 1 close to the squeezing column 6. The side of the connecting rod 16 away from the support frame 1 is fixedly connected to an adjustment plate 17, which plays the role of connecting the support frame 1 and the adjustment plate 17, connecting the support frame 1 with the mounting structure related to the membrane cloth roller 20, and ensuring the stability and integrity of the entire mounting component in the device.

[0040] The interior of the adjustment plate 17 is provided with a plurality of adjustment slots 18. The adjacent sides of the two adjustment plates 17 are rotatably connected to the film cloth roller 20. The adjustment plate 17 can adjust the height of the film cloth roller 20 by cooperating with the adjustment slots 18 and the fixed column 19, thereby adapting to different ground heights for laying the ground film. It is a storage and transportation component for the ground film. When laying the ground film, the film cloth is pulled out from the outside of the film cloth roller 20. As the device moves, the film cloth is laid on the ground under the action of the pressure wheel 15. The rotation characteristics of the film cloth roller 20 ensure that the film cloth can be pulled out and laid smoothly, and its height can be adjusted by installing the assembly to adapt to different ground conditions.

[0041] The outside of the support frame 1 is fixedly connected to two fixed columns 19. The outside of the fixed columns 19 is slidably connected to the inner wall of the adjustment groove 18. The fixed columns 19 slide in the adjustment groove 18 and are fixed by nuts. The film roller 20 can be adjusted to a suitable height according to the actual ground height to ensure the tension and laying effect of the film during the laying process. The external thread of the fixed columns 19 is connected to a nut. The side of the support frame 1 away from the extrusion column 6 is fixedly connected to two handles 21, which are convenient for the operator to hold and pull the entire device. The outside of the support frame 1 is rotatably connected to multiple moving wheels 22, allowing the device to move smoothly on the ground.

[0042] Working principle: First, place the support frame 1 in the appropriate position, then pull out the membrane cloth outside the membrane cloth roller 20, place the corners of the membrane cloth on the ground, then remove the fixing plate 3 from the placement slot 2, insert the extrusion column 6 through the membrane cloth into the soil, then press the pressure block 5 to make the pressure rod 4 push the extrusion column 6 downward, and at the same time, the rotating rod 8 will expand to both sides, and the spring 11 will be stretched to generate tension on the rotating rod 8, which can fix the extrusion column 6 inside the soil. After use, press the rotating rod 8 inward to compress the spring 11, and at the same time, the outer sleeve 10 slides on the outside of the inner sleeve 9, which can move the rotating rod 8 to the inner wall of the slide 7, making it easier to pull out the extrusion column 6.

[0043] The support frame 1 is then pulled to move by the handle 21 and the moving wheel 22. During the movement, the membrane cloth is laid on the ground, and at the same time, the membrane cloth contacts the pressure wheel 15. The pressure wheel 15 is forced to squeeze the sliding column 12 upward due to the different heights of the ground. At the same time, the spring 2 14 is compressed. When compressed, the spring 2 14 will generate a reaction force on the sliding column 12 and the pressure wheel 15. The limiting plate 13 limits the sliding column 12 to prevent it from falling off. At the same time, the pressure wheel 15 is in closer contact with the membrane cloth, so that the membrane cloth is in closer contact with the ground, which can ensure the flatness of the membrane cloth.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
