Description

Technical Field

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

[0002] Potato cultivation is a series of agricultural production processes, from seed potato selection and treatment, land preparation and fertilization, sowing to field management and harvesting. It requires scientific management based on its growth characteristics to achieve high quality and high yield. When it is necessary to increase soil temperature (such as in low-temperature areas or spring sowing), retain water and moisture (such as in arid areas or areas with little rainfall), suppress weeds, pursue large-scale planting efficiency, or improve soil structure (such as in clay or sandy soils), potato planting mulching machines are used. These machines can meet the corresponding planting needs through mulching and integrated operations.

[0003] The existing utility model with authorization announcement number CN221488269U discloses a potato planting device with plastic film mulching. It has a simple structure, is easy to operate, and can plant potatoes very quickly, saving a lot of manpower and resources. Moreover, after planting potatoes, a layer of plastic film can be covered on the surface of the soil mound to lock in the water and fertilizer of the surrounding soil. The curvature of the film can also be adjusted according to the curvature of the soil mound, so that the plastic film can be better applied to the soil mound. It is very portable and convenient.

[0004] While the above-mentioned technical solutions can cover the surface of the soil mound with a layer of mulch film, and the curvature of the mulch film can be adjusted according to the curvature of the soil mound to ensure better application, the roller structure for storing the mulch film is in a relatively fixed position, making quick disassembly inconvenient. The lack of a convenient replacement structure for the mulch film roller structure leads to inconvenience in replacement, affecting the efficiency of subsequent continuous operation of the mulching machine. Therefore, a potato planting mulching machine is proposed here. Utility Model Content

[0005] This utility model proposes a potato planting mulching machine to solve the problem that the replacement of the mulch film roller structure in the prior art is inconvenient and affects the efficiency of subsequent continuous operation of the mulching machine.

[0006] This utility model is achieved through the following technical solution: a potato planting and mulching machine, including a frame, four soil-turning and traveling wheels are provided on the outer side of the frame, and a limit rotating rod is fixedly connected to the side of each soil-turning and traveling wheel near the frame. The frame is provided with a convenient replacement mechanism.

[0007] The convenient replacement mechanism includes two irregularly shaped brackets. Each irregularly shaped bracket has a movable frame and a guide rod slidably connected inside. The frame is equipped with a ground film roller, and a pull plate is provided above the ground film roller. Each guide rod has a return spring sleeved on its outer surface. Each movable frame has two first support rods fixedly connected to its inner wall. Each first support rod has a first rubber roller rotatably connected to its outer surface. Each irregularly shaped bracket has two second support rods fixedly connected to its inner wall. Each second support rod has a second rubber roller rotatably connected to its outer surface.

[0008] Specifically, the outer surface of each limiting rotating rod is rotatably connected to the inner wall of the frame, the upper surface of each irregular bracket is fixedly connected to the inner top wall of the frame, the bottom end of each guide rod is fixedly connected to the upper surface of the movable frame, the top end of each guide rod is fixedly connected to the bottom surface of the pull plate, the upper surface of each irregular bracket is in contact with the bottom surface of the pull plate, the two ends of each return spring are in contact with the inner top wall of the irregular bracket and the upper surface of the movable frame, the outer surfaces of each first rubber roller and second rubber roller are in contact with the outer surface of the ground film roller, and two handle rods are fixedly connected to the upper surface of the frame, with an anti-slip sleeve fixedly connected to the outer surface of each handle rod.

[0009] Furthermore, two connecting rods are fixedly connected to the inner top wall of the frame, and a suspension is fixedly connected to the bottom end of each connecting rod.

[0010] Each suspension has a fixed rod fixedly connected to its inner wall, and a side pressure roller is rotatably connected to the outer surface of each fixed rod.

[0011] Preferably, a handle support is fixedly connected to the upper surface of the pull plate, and a pull rod is fixedly connected to the inner wall of the handle support.

[0012] Furthermore, each of the handle supports is provided with a grip inside, and the inner wall of the grip is rotatably connected to the outer surface of the pull rod.

[0013] This utility model provides a potato planting mulching machine, which has the following beneficial effects:

[0014] This potato planting mulching machine, through the coordinated operation of a frame, soil-turning wheels, a limiting rotating rod, a special-shaped support, a pull plate, a mulch film roller, a movable frame, a guide rod, a return spring, a first support rod, a first rubber roller, a second support rod, and a second rubber roller, allows the soil-turning wheels and the limiting rotating rod to facilitate the movement of the frame and the mulch film roller along the potato field. The mulch film roller can be wound with enough mulch film for potato planting. When the mulch film on the roller needs to be replaced, pulling the pull plate upwards will pull the movable frame away from both ends of the mulch film roller via the guide rod. This design facilitates the removal of the mulch film roller from between the irregular support and the movable frame. Then, a new mulch film roller with sufficient mulch film is placed between the irregular support and the movable frame at both ends. The mulch film roller continues to roll under the rotation of the first and second rubber rollers. Therefore, replacing the mulch film roller only requires pulling and releasing the pull plate and picking up and placing the mulch film roller, increasing the continuous operating efficiency of the entire mulching machine. This avoids the problem of inconvenient mulch film roller replacement due to the lack of a convenient replacement structure, which could affect the subsequent continuous operating efficiency of the mulching machine.

[0026] Please see Figures 1 to 7 This utility model provides a potato planting mulching machine, including a frame 1. Four soil-turning wheels 2 are arranged on the outer side of the frame 1. The external structure of the soil-turning wheels 2 facilitates movement on the potato planting field and provides a certain soil-turning effect during movement. Each soil-turning wheel 2 is fixedly connected to a limit rotating rod 3 on the side near the frame 1. A convenient replacement mechanism 4 is provided inside the frame 1. The convenient replacement mechanism 4 includes two irregularly shaped brackets 401, each of which has a movable frame slidably connected inside. 404 and guide rod 405, the outer surface of each limiting rotating rod 3 is rotatably connected to the inner wall of the frame 1, the upper surface of each irregular bracket 401 is fixedly connected to the inner top wall of the frame 1, the bottom end of each guide rod 405 is fixedly connected to the upper surface of the movable frame 404, and two pull handles 5 are fixedly connected to the upper surface of the frame 1. Each pull handle 5 has an anti-slip sleeve 6 fixedly connected to its outer surface. By setting the pull handles 5, it is convenient to pull the entire mulching machine to move in the potato field. By setting the anti-slip sleeve 6, the anti-slip property of the outer surface of the pull handle 5 can be increased.

[0027] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 7 The vehicle frame 1 is equipped with a mulch film roller 403, which is pre-wound with a sufficient amount of mulch film. When the mulch film on the mulch film roller 403 is used up, it can be replaced along with the mulch film roller 403. A pull plate 402 is set above the mulch film roller 403. The top of each guide rod 405 is fixedly connected to the bottom surface of the pull plate 402. The upper surface of each irregular bracket 401 is in contact with the bottom surface of the pull plate 402. Two connecting rods 7 are fixedly connected to the inner top wall of the vehicle frame 1. A suspension 8 is fixedly connected to the bottom end of each connecting rod 7. By setting the connecting rods 7, the vehicle frame 1 and the suspension 8 can be connected. By setting the suspension 8, it can work with other structures to press down on both sides of the mulch film and make the mulch film adhere tightly to the soil.

[0028] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 Each guide rod 405 has a return spring 406 fitted on its outer surface. The two ends of each return spring 406 are in contact with the inner top wall of the irregular bracket 401 and the upper surface of the movable frame 404, respectively. Each movable frame 404 has two first support rods 407 fixedly connected to its inner wall. Each suspension 8 has a fixed rod 9 fixedly connected to its inner wall. Each fixed rod 9 has a side pressure roller 10 rotatably connected to its outer surface. By setting the fixed rod 9, a rotation base surface can be provided for the side pressure roller 10, so that the side pressure roller 10 can press down on both sides of the mulch film wrapped on the mulch film roller 403 and make the mulch film adhere tightly to the soil.

[0029] Please refer to this carefully. Figure 3 , Figure 4 , Figure 5 and Figure 6 Each first support rod 407 has a first rubber roller 408 rotatably connected to its outer surface. The first rubber roller 408 has good elasticity and anti-slip properties. Each irregular bracket 401 has two second support rods 409 fixedly connected to its inner wall. The upper surface of the pull plate 402 is fixedly connected to a handle support 11. The inner wall of the handle support 11 is fixedly connected to a pull rod 12. By setting the pull rod 12, a rotation base surface can be provided for the hand grip structure inside the handle support 11. By setting the handle support 11 and the pull rod 12, the pull plate 402 can be lifted together with the above-mentioned hand grip structure, so as to facilitate the upward pulling of the movable frame 404 through the guide rod 405.

[0030] Please refer to this carefully. Figure 1 , Figure 3 , Figure 4 and Figure 5 Each second support rod 409 has a second rubber roller 410 rotatably connected to its outer surface. The second rubber roller 410 has good elasticity and anti-slip properties. The outer surfaces of each first rubber roller 408 and the second rubber roller 410 are in contact with the outer surface of the film roller 403. Each handle support 11 has a handle 13 inside. The inner wall of the handle 13 is rotatably connected to the outer surface of the pull rod 12. By setting the handle 13, it can rotate around the outer surface of the pull rod 12 inside the handle support 11. Then, by holding the handle 13, the pull plate 402 can be lifted, which makes it convenient to pull the movable frame 404 up through the guide rod 405.

[0031] In summary, when using this utility model: First, during use, the soil-turning wheel 2 rotates on both sides of the frame 1 via the limiting rotating rod 3. Pulling the handle 5 in the direction of film covering can drive the whole unit to move along the planting area. At the same time, the soil-turning wheel 2 performs soil turning and pretreatment. The anti-slip sleeve 6 increases the grip stability of the handle 5 and prevents it from slipping out of the hand during operation.

[0032] When the mulch film on the mulch film roller 403 is used up and needs to be replaced, pull the handle 13 upwards. The pull rod 12 and the handle support 11 will drive the pull plate 402 to rise. The guide rod 405 will move upwards with the pull plate 402. The movable frame 404 will rise synchronously and compress the return spring 406. The first rubber roller 408 will detach from the surface of the mulch film roller 403. At this time, the old mulch film roller 403 can be removed from between the irregular bracket 401 and the movable frame 404.

[0033] After inserting the new film mulch roller 403, release the handle 13. The return spring 406 resets and pushes the movable frame 404 downward. The first rubber roller 408 and the second rubber roller 410 clamp the film mulch roller 403 together, ensuring its stable rotation and film supply. During the mulching process, the side pressure roller 10 rotates on the suspension 8 via the fixed rod 9, pressing both sides of the film mulch into the soil to ensure the film adheres to the ground surface, thus completing the mulching operation. The design of the entire potato planting mulching machine effectively solves the problem that the lack of a convenient replacement structure for the film mulch roller 403, which makes the replacement of the film mulch roller 403 inconvenient and affects the efficiency of subsequent continuous operation of the mulching machine, is due to the inconvenience of replacing the film mulch roller 403.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
