Description

Technical Field

[0001] This utility model relates to the field of agricultural planting mulch film laying technology, and in particular to an agricultural planting mulch film laying device. Background Technology

[0002] Mulch not only increases soil temperature, retains water, soil, and fertilizer, improving fertilizer efficiency, but also has multiple functions such as weed control, pest and disease prevention, drought and flood resistance, salt suppression and seedling protection, improvement of near-surface light and heat conditions, and hygiene and cleanliness. For newly emerged seedlings, it has the effect of protecting roots and promoting growth.

[0003] Patent application number CN202221361594.5 discloses an agricultural mulch film laying device, including two mounting rods, each with a sleeve fixedly installed at its end; a stabilizing rod is slidably sleeved inside the sleeve and locked by fastening bolts; a pull rod is slidably sleeved on the stabilizing rod; and rollers are installed on the mounting rods. This invention proposes an agricultural mulch film laying device. The sliding connection between the sleeve and the stabilizing rod facilitates changing the distance between right-angle blocks, thereby placing the rolled mulch film. A shovel is used to loosen the soil, and after the mulch film is laid, the shovel covers the soil up to the edge of the mulch film, making it easy for one person to operate. However, although the above device can lay the mulch film, after the mulch film is laid in one location, the worker still needs to manually cut the mulch film, causing inconvenience and reducing laying efficiency.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that cutting mulch film after laying is inconvenient, and to propose a mulch film laying device for agricultural planting.

[0006] The technical solution of this utility model: An agricultural mulch film laying device, comprising a main support, two symmetrically distributed mounting frames fixed to one side of the outer surface of the main support, wheels rotatably connected to the inner side of the mounting frames, brackets fixed to both sides of the main support, and a film covering cylinder disposed between the two brackets, and further comprising:

[0007] A film cutting mechanism is installed on the surface of the main support and is used for cutting the film on the film coating cylinder;

[0008] The support rods are provided in two symmetrically distributed and fixed to one side of the main support. A handle is fixed between the ends of the two support rods, and the surface of the handle is provided with an extrusion assembly that cooperates with the film cutting mechanism.

[0009] Optionally, the film cutting mechanism includes:

[0010] Two fixed blocks are provided and symmetrically distributed and fixed to the inner side of the main support. A movable rod is movably passed through the surface of the fixed block.

[0016] Compared with the prior art, this application includes the following beneficial technical effects:

[0017] 1. This utility model realizes the function of laying mulch film through the setting of main support, film covering cylinder and wheels. At the same time, after a piece of soil is laid, through the cooperation between the film cutting mechanism and the extrusion component, the workers do not need to bend over to cut the mulch film. The workers only need to lift the pull rod, so that the pressure rod squeezes the guide rail, thereby driving the cutter to move down and cut the mulch film. Then, under the elastic force of the spring, the cutter returns to its original position, which greatly improves the convenience of cutting during the laying process and improves the laying efficiency of mulch film.

[0018] 2. In this utility model, the film covering cylinder is sleeved on the connecting shaft, and then the connecting shaft is placed in the groove, which facilitates the rotation of the film covering cylinder and also makes it easy to replace the film covering cylinder. During the laying process, the soil breaking board is used to dig pits on both sides of the soil, so that the wheels move along the pits after the soil breaking. Then the film is laid as the main support moves. At the same time, the soil covering board scrapes the soil on both sides of the pit into the pit, thereby covering and compacting the film.

[0027] like Figure 1-4 As shown, the present invention proposes an agricultural mulch film laying device, including a main support 1. Two symmetrically distributed mounting frames 2 are fixed on one side of the outer surface of the main support 1. Wheels 3 are rotatably connected to the inner side of the mounting frames 2. Brackets 4 are fixed on both sides of the main support 1. A film covering cylinder 8 is arranged between the two brackets 4. By pulling the main support 1, the wheels 3 are driven to rotate, thereby driving the film covering cylinder 8 on the brackets 4 to rotate, thereby laying the mulch film.

[0028] Two symmetrically distributed connecting rods 9 are fixed on one side of the main support 1, and a soil covering plate 10 is fixed to the end of the connecting rod 9. Two symmetrically distributed fixing frames 11 are fixed on the other side of the main support 1. A soil breaking plate 12 is fixed inside the fixing frame 11. During the movement of the main support 1, the soil breaking plate 12 and the soil covering plate 10 are moved. During the laying process, the soil breaking plate 12 is used to dig pits on both sides of the soil, so that the wheels 3 move along the pits after the soil is broken. Then the mulch film is laid during the movement of the main support 1. At the same time, the soil covering plate 10 scrapes the soil on both sides of the pit into the pit, thereby covering and compacting the mulch film with soil.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 4 It also includes a film cutting mechanism, which is set on the surface of the main support 1 and used to cut the film on the film covering cylinder 8. The film cutting mechanism includes a fixing block 18. There are two fixing blocks 18, which are symmetrically distributed and fixed to the inner side of the main support 1. A movable rod 19 is movably passed through the surface of the fixing block 18. A connecting block 21 is fixed at the bottom end of the movable rod 19. A cutter 20 is fixed between the two connecting blocks 21. A spring 22 is sleeved on the outer surface of the movable rod 19. One end of the spring 22 is fixed to the surface of the fixing block 18, and the other end of the spring 22 is fixed to the surface of the connecting block 21. After the soil is covered with film, the film needs to be cut by personnel. In this device, the personnel press down the cutter 20 to make the cutter 20 move down to cut the film. After cutting, the cutter 20 returns to its original position under the elastic force of the spring 22, which facilitates the cutting of the film.

[0030] Furthermore, such as Figure 1 and Figure 4 Support rod 13, two of which are symmetrically distributed and fixed to one side of the main support 1. A handle 14 is fixed between the ends of the two support rods 13. The surface of the handle 14 is provided with an extrusion assembly that cooperates with the film cutting mechanism. The extrusion assembly includes a movable ring 15, which is rotatably sleeved on the outer surface of the handle 14. A pressure rod 16 is fixed on the outer surface of the movable ring 15. A support rod 23 is fixed in the middle of the top surface of the cutter 20. A guide rail 24 is fixed at the top of the support rod 23. The end of the pressure rod 16 is located inside the guide rail 24. A pull rod 17 is fixed on the outer surface of the movable ring 15. By lifting the pull rod 17, the movable ring 15 is driven to rotate on the handle 14, thereby driving the pressure rod 16 to move downward and then move within the guide rail 24, causing the guide rail 24 to move downward. This, in turn, drives the cutter 20 to move downward through the support rod 23, facilitating the movement of the cutter 20.

[0031] It should be noted that, for example Figure 3 The bracket 4 has a groove 5 on its surface, and a connecting shaft 6 is placed between the grooves 5. The two ends of the connecting shaft 6 are fixed with limiting blocks 7 that cooperate with the grooves 5. The film coating cylinder 8 is sleeved on the connecting shaft 6, and then the connecting shaft 6 is placed in the groove 5, which facilitates the rotation of the film coating cylinder 8 and also facilitates the replacement of the film coating cylinder 8.

[0032] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
