[0001] This utility model belongs to the field of mulching machine technology, specifically relating to a potato planting mulching machine. Background Technology

[0002] A potato mulching machine is a specialized machine used for planting potatoes. It is mainly used to simultaneously complete processes such as ridging, mulching, and punching holes during planting to improve the soil's water and fertilizer retention capacity, suppress weed growth, and promote seedling growth.

[0003] However, existing potato mulching machines often lack the function of stepless adjustment of the mulching roller height, and often achieve multiple levels of adjustment through multiple holes, causing inconvenience during use. In addition, existing potato mulching machines often lack the function of quick installation and removal of the mulching roller, resulting in reduced installation and removal efficiency. Therefore, there is an urgent need for a potato planting mulching machine to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a potato planting mulching machine to solve the problems mentioned in the background art that existing potato mulching machines often do not have the function of steplessly adjusting the height of the mulching roller, and that existing potato mulching machines often do not have the function of quickly installing and disassembling the mulching roller.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a potato planting mulching machine, comprising a mulching machine body, a support plate, an adjustment structure, and an installation structure. The mulching machine body includes a bracket, with support plates fixedly connected to both the front and rear ends of the bracket. The adjustment structure includes a slide rail, which is fixedly connected to the outer wall of the support plate. The slide rail is slidably connected to a slide rod, and a support rod is fixedly connected to the outer wall of the top of the slide rod. A threaded rod is fixedly connected to the support rod, and a limiting seat is threadedly connected to the threaded rod. The limiting seat abuts against the outer wall of the slide rail. The installation structure includes a support frame, with the top of the support frame fixedly connected to two slide rods. A protrusion is provided at the bottom of the front end of the support frame, and the protrusion of the support frame is rotatably connected to a fixed seat via a hinge. A limiting post is fixedly connected to the bottom end of the fixed seat, and two fixed plates are fixedly connected to the top of the fixed seat, with the fixed plates located on the left and right sides of the protrusion. Pins are inserted into the protrusion and fixed plates of the support frame. A limiting post is fixedly connected to the rear end of the support frame, and the two limiting posts are rotatably connected to a mulching roller.

[0006] Preferably, the support plate is fixedly connected to the bracket by two fixing bolts.

[0007] Preferably, the slide rail has a groove in the middle, and the support rod slides within the groove of the slide rail.

[0008] Preferably, the limiting seat is T-shaped, and the outer wall of the limiting seat is fixedly connected to the handle.

[0009] Preferably, the grip is a hexagonal grip and has an anti-slip coating on its surface.

[0010] Preferably, a pull ring is provided on the right side of the pin, and a pin is inserted into the left end of the pin.

[0011] Preferably, the protrusion of the support frame is provided with a socket, and the fixing plate is provided with a socket corresponding to the socket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This potato planting mulching machine is equipped with an adjustment structure. When the height of the mulching roller needs to be adjusted, the user rotates the handle, causing the fixed limit seat to rotate. When the limit seat is loosened, the friction between it and the slide rail decreases. At this time, the operator can drag the entire installation structure up and down, causing the slide rod to slide freely within the slide rail, thereby quickly adjusting the mulching roller to the required height. At the same time, the support rod slides up and down with the slide rod within the slide rail groove. After adjustment, the limit seat is tightened in the reverse direction, using the friction between it and the slide rail to firmly lock the entire mechanism in the current position, ensuring stability during operation. By using a combination of threaded joints and friction locking in the adjustment structure, stepless adjustment of the mulching roller height is achieved. The T-shaped limit seat provides a large contact area and a large locking force, effectively preventing height deviation caused by vibration during mulching and ensuring the stability of mulching quality.

[0014] 2. This potato planting mulching machine is equipped with an installation structure. The mulching roller is rotatably connected to the installation structure through the limiting posts at both ends. When installing the mulching roller, first insert one end of the mulching roller into the limiting post of the support frame, and then rotate the fixing seat to make it abut against the support frame. At this time, the two fixing plates on the fixing seat are aligned with the insertion holes on the protrusions of the support frame. Finally, insert the pin into the aligned insertion hole to complete the locking. The installation structure adopts a quick locking scheme of hinge and pin, which eliminates the cumbersome steps of traditional bolt fixing, making the replacement of the mulching roller convenient and quick, improving installation efficiency and making it easy to use.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a potato planting mulching machine, comprising a mulching machine body 1, a support plate 2, an adjustment structure 3, and an installation structure 4. The mulching machine body 1 includes a bracket 11, with the support plate 2 fixedly connected to both the front and rear ends of the bracket 11. The adjustment structure 3 includes a slide rail 31, which is fixedly connected to the outer wall of the support plate 2. The slide rail 31 is slidably connected to a slide rod 32, and a support rod 33 is fixedly connected to the outer wall of the top end of the slide rod 32. The support rod 33 is fixedly connected to a threaded rod 34, and the threaded rod 34 is threadedly connected to a limiting seat 35, which abuts against the slide rail 31. On the outer wall, the mounting structure 4 includes a support frame 41. The top of the support frame 41 is fixedly connected to two sliding rods 32. A protrusion is provided at the bottom front end of the support frame 41. The protrusion of the support frame 41 is rotatably connected to a fixed seat 44 via a hinge 43. A limiting post 45 is fixedly connected to the bottom end of the fixed seat 44. Two fixing plates 46 are fixedly connected to the top of the fixed seat 44, and the fixing plates 46 are located on the left and right sides of the protrusion. The protrusion of the support frame 41 and the fixing plates 46 are both inserted with pins 47. The rear end of the support frame 41 is fixedly connected to the limiting post 45. The two limiting posts 45 are rotatably connected to a coating roller 48.

[0023] Furthermore, the support plate 2 is fixedly connected to the bracket 11 by two fixing bolts 21. This connection method ensures the connection strength and stability between the support plate 2 and the bracket 11.

[0024] Furthermore, a groove is provided in the middle of the slide rail 31, and the support rod 33 slides in the groove of the slide rail 31. The groove provides precise guidance and constraint for the support rod 33, ensuring that it slides smoothly and steadily in the vertical direction.

[0025] Furthermore, the limiting seat 35 is T-shaped, and the handle 36 is fixedly connected to the outer wall of the limiting seat 35. The T-shaped design allows the limiting seat 35 to form a larger contact area with the outer wall of the slide rail 31.

[0026] Furthermore, the grip 36 is a hexagonal grip with a non-slip coating on the surface. The hexagonal grip is ergonomically designed for easy gripping and force application, and the non-slip coating effectively increases friction.

[0027] Furthermore, a pull ring is provided on the right side of the pin 47, and a pin is inserted into the left end of the pin 47. The pull ring design allows the operator to easily pull the pin 47 with their fingers without tools, which greatly simplifies the operation steps. The pin inserted into the left end serves as a safety device to prevent it from falling off.

[0028] Furthermore, the protrusion of the support frame 41 is provided with an insertion hole 42, and the fixing plate 46 is provided with an insertion hole corresponding to the insertion hole 42. The insertion hole 42 on the protrusion of the support frame 41 and the insertion hole on the fixing plate 46 together form a precisely aligned channel.

[0029] Working Principle: When adjusting the height of the coating roller 48, the user rotates the handle 36, causing the fixed limiting seat 35 to rotate. When the limiting seat 35 is loosened, the friction between it and the slide rail 31 decreases. At this time, the operator can drag the entire mounting structure 4 up and down, causing the slide rod 32 to slide freely within the slide rail 31, thus quickly adjusting the coating roller 48 to the required height. Simultaneously, the support rod 33 slides up and down with the slide rod 32 within the groove of the slide rail 31. After adjustment, the limiting seat 35 is tightened in the opposite direction, using the friction between it and the slide rail 31 to firmly lock the entire mechanism in the current position, ensuring stability during operation. By using a combination of threaded joints and friction locking in the adjustment structure 3, stepless adjustment of the coating roller 48 height is achieved. The T-shaped limiting seat 35 provides a large contact area and strong locking force, effectively preventing height deviation caused by vibration during the coating process. The shifting mechanism ensures the stability of the coating quality. The coating roller 48 is rotatably connected to the mounting structure 4 via the limiting posts 45 at both ends. When installing the coating roller 48, first insert one end of the coating roller 48 into the limiting post 45 of the support frame 41, and then rotate the fixing seat 44 so that it abuts against the support frame 41. At this time, the two fixing plates 46 on the fixing seat 44 are aligned with the insertion holes 42 on the protrusions of the support frame 41. Finally, insert the pin 47 into the aligned insertion hole to complete the locking. By using the quick locking scheme of hinge 43 and pin 47 in the mounting structure 4, the cumbersome steps of traditional bolt fixing are eliminated, making the replacement of the coating roller 48 convenient and quick, improving installation efficiency, and facilitating use.
