DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0030] A drip irrigation belt laying ring-type soil covering device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it includes a base plate 10, which is fixedly placed on the ground; a guide structure, which is movably arranged on the top surface of the base plate 10, and the guide structure includes a gear 18, an open groove ring 21 and an open toothed ring 22, the gear 18 is rotatably arranged on the top surface of the base plate 10, the open groove ring 21 is fixedly arranged on the top surface of the base plate 10, the open toothed ring 22 is slidably arranged in the open groove ring 21, and the open toothed ring 22 is transmission-arranged on one side of the gear 18; a soil covering structure, which is slidably arranged on the open groove ring 21, and the soil covering structure includes a bracket 11, a soil covering wheel 14, a support plate 15, a telescopic rod 16, a handle threaded rod 28, a moving block 30 and a connecting rod 31, the support plate 15 and the telescopic rod 16 are both fixedly connected to the bracket 11, the soil covering wheel 14 is movably arranged on one side of the support plate 15, the moving block 30 is slidably arranged in the support plate 15, the handle threaded rod 28 is threadedly arranged in the moving block 30, the handle threaded rod 28 is rotatably arranged in the support plate 15, and the connecting rod 31 is rotatably arranged above the moving block 30.

[0031] The working principle is as follows. By setting a guiding structure, the device controls the rotation of gear 18 by twisting the rotating handle 19. Gear 18 meshes with the open tooth ring 22 to drive the soil covering structure to lay soil on the drip irrigation tape in a circular shape. During use, only manual twisting of the rotating handle 19 is required to control the soil covering direction and angle of the device, eliminating the need for manual pushing of the entire device. This not only facilitates operation but also reduces the workload of farmers. By setting the soil covering structure, the distance between the two soil covering wheels 14 is determined according to the size of the drip irrigation tape, and the circular laying diameter is determined according to the size of the laying area. Then, the telescopic rod 16 is stretched to expand or contract the laying range. The position of the moving block 30 is controlled by rotating the handle threaded rod 28, causing the moving block 30 to push the connecting rod 31, which in turn pushes the soil covering wheel 14 to change the angle and spacing, thereby meeting the laying requirements of drip irrigation tapes of different sizes and improving the applicability of the device.

[0032] As Figure 1 and Figure 3 shown, the bottom plate 10 is an arc-shaped plate. The top surface of the bottom plate 10 is fixedly connected to the open slot ring 21. The inner side of the open slot ring 21 corresponds to the inner side of the bottom plate 10. The outer side of the open slot ring 21 is provided with an annular groove. The inner side of the open tooth ring 22 is fixedly connected to an open sliding ring 23, and the open sliding ring 23 rotates and slides in the annular groove of the open slot ring 21; As Figure 1 、 Figure 2 、 Figure 3 and Figure 6 shown, the top surface of the bottom plate 10 is fixedly connected to a fixed column 20. The top surface of the gear 18 is fixedly connected to a rotating handle 19. A circular groove is formed between the gear 18 and the rotating handle 19. The fixed column 20 is rotatably connected in the circular groove, and the gear 18 is in transmission engagement with the open tooth ring 22; As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, one end of the top surface of the open tooth ring 22 is fixedly connected to a fixed block 17. The fixed block 17 is an L-shaped block. The fixed block 17 slides on the top surface of the open slot ring 21. One side of the fixed block 17 close to the gear 18 is fixedly connected to the telescopic rod 16, and the output end of the telescopic rod 16 is connected to one side of the bracket 11.

[0033] The working principle is as follows. The cross-section of the open slot ring 21 is U-shaped. The overall shapes of the open slot ring 21, the open tooth ring 22, and the open sliding ring 23 are all in the form of a C shape. The opening of the open slot ring 21 is larger than the openings of the open tooth ring 22 and the open sliding ring 23. The openings of the open tooth ring 22 and the open sliding ring 23 are of the same size. The inner vertical surface of the fixed block 17 is set as an arc surface corresponding to the inner side of the open slot ring 21. When in use, first determine according to the length of the bottom plate 10 and the diameter of the ground to be laid, and then adjust the telescopic length of the telescopic rod 16 to determine the laying radius of the drip irrigation tape of the device. Then twist the rotating handle 19. The rotating handle 19 drives the gear 18 to drive and engage the open tooth ring 22, so that the open tooth ring 22 slides around in the open slot ring 21 with the help of the open sliding ring 23. At this time, the open tooth ring 22 drives the fixed block 17 and the telescopic rod 16 to rotate around the bottom plate 10. At this time, the laying track of the device is circular. Here, there is a possibility that the telescopic rod 16 is above the rotating handle 19 during the movement process. At this time, the telescopic rod 16 has a certain blockage of the rotating handle 19, but the blocked part does not prevent the farmer from twisting the rotating handle 19.

[0034] As Figure 1 and Figure 4 shown, the bracket 11 is a square column structure. There is a square groove on the top surface of the bracket 11. A tape winding roller 12 is fixedly connected inside the square groove. One side of the bracket 11 is fixedly connected with a guide wheel 13 and a support plate 15. The support plate 15 is directly below the guide wheel 13. The guide wheel 13 and the support plate 15 are both on the adjacent sides of the telescopic rod 16. There are a laying port 24, a chute 25, a rotating hole 27, and two slideways 26 inside the support plate 15. The laying port 24 is perpendicular to the chute 25. The laying port 24 is directly below the guide wheel 13. The two slideways 26 are symmetrically arranged with the chute 25 as the center. The rotating hole 27 communicates with the chute 25; As Figure 1 、 Figure 4 and Figure 5 shown, a handle threaded rod 28 is rotatably connected between the chute 25 and the rotating hole 27. The moving block 30 is a T-shaped block. There is a threaded hole inside the moving block 30. Two cylinders are symmetrically fixed on the top surface of the moving block 30. The moving block 30 slides in the chute 25. The moving block 30 is threadedly connected with the handle threaded rod 28 through the threaded hole. A sliding column 32 is slidably connected in each of the two slideways 26. A short column is fixedly connected to the top surface of the sliding column 32. Through holes are opened at both ends of the connecting rod 31. The connecting rod 31 is rotatably connected to the cylinder and the short column through the through holes at both ends respectively; As Figure 5 shown, a connecting block 29 is fixedly connected to the bottom surface of the sliding column 32. A round shaft is rotatably arranged inside the connecting block 29. The end of the round shaft away from the support plate 15 is rotatably connected to a soil covering wheel 14. There are two soil covering wheels 14 symmetrically arranged. The two soil covering wheels 14 are respectively on both sides of the support plate 15.

[0035] The specific implementation is as follows. The overall shape of the soil covering wheel 14 is approximately conical. The part of the soil covering wheel 14 close to the connecting block 29 is slightly inclined, and an angle less than 90 degrees is formed between the soil covering wheel 14 and the ground to help cover the drip irrigation tape with soil. Specifically, before use, the distance between the two soil covering wheels 14 on both sides of the support plate 15 is determined according to the size of the drip irrigation tape. The moving distance of the moving block 30 in the sliding groove 25 is controlled by rotating the handle threaded rod 28. Then, by means of the movement of the moving block 30, the two side connecting rods 31 are mobilized to push or pull their respective corresponding sliding columns 32. The two side sliding columns 32 slide in their respective corresponding sliding grooves 26. Since the shape of the sliding groove 26 is similar to a semi-circle, the angle of each slide of the sliding column 32 is different. Correspondingly, the connecting block 29 driven by the sliding column 32 and the soil covering wheel 14 driven by the connecting block 29 will have different angle and position changes. After determining the soil covering angles and the distance between the two soil covering wheels 14, the telescopic rod 16 is stretched according to the length of the bottom plate 10 and the diameter of the ground to be laid to determine the laying radius. Then, the drip irrigation tape to be laid is wound on the tape winding roller 12. The laying end of the drip irrigation tape is inserted into the gap between the guiding wheel 13 and the bracket 11 and the laying port 24, and the laying end is buried in the soil. The rotating handle 19 is twisted, and the rotating handle 19 drives the gear 18 to be in transmission engagement with the open tooth ring 22. The open tooth ring 22 drives the fixed block 17 and the telescopic rod 16 to make a circular rotation around the bottom plate 10. The bracket 11 drives the support plate 15 to move synchronously. The soil covering wheels 14 on both sides of the support plate 15 rotate synchronously to cover the soil on both sides on the drip irrigation tape, realizing circular soil covering.
