Description

Technical Field

[0001] This utility model relates to the field of sowing technology, and more specifically, to a potato planter with a mulching function. Background Technology

[0002] In potato cultivation, the use of planters greatly improves planting efficiency and crop yield. However, traditional potato planters have some shortcomings in their mulching function, especially in terms of mulching replacement and removal. The mulching mechanism of traditional potato planters is directly fixed to the planter frame using multiple bolts or screws, or installed through some complex connection mechanism. This design means that when replacing or removing the mulching rollers, operators need to use tools to tighten or loosen the bolts or screws, which is not only time-consuming and labor-intensive but also increases the difficulty of operation.

[0003] In addition, when laying the mulch film, its ends need to pass under the pressure roller first, and then as the seeder moves forward, the pressure roller presses and flattens the mulch film that has passed underneath.

[0004] Because the pressure roller is initially in contact with the ground under the influence of gravity, the film needs to be lifted manually during the film laying process. Then the film is passed under the pressure roller and gradually laid flat. This process is difficult for a single person to operate and can easily cause the film passing under the pressure roller to pile up and tangle together, resulting in unevenness and affecting subsequent film laying.

[0005] To address the aforementioned issues, a potato planter with a mulching function has been proposed. Utility Model Content

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0039] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0040] For examples, please refer to Figure 1 - Figure 7 A potato planter with a film covering function includes a planter 1, and a film covering mechanism 2 and a film pressing mechanism 3 are provided on the frame of the planter 1. The film covering mechanism 2 is located on the side of the planter 1 near the handle, and the film pressing mechanism 3 is located on the side of the film covering mechanism 2 away from the planter 1.

[0041] The film covering mechanism 2 includes a quick-release assembly 4 mounted on the frame of the seeder 1, and a roll film covering 201 mounted on the quick-release assembly 4;

[0042] The film pressing mechanism 3 includes an I-shaped frame 301 mounted on the frame of the seeder 1, a film pressing assembly 5 rotatably mounted on the I-shaped frame 301, and a lifting and positioning assembly 6 matched on the I-shaped frame 301 and the film pressing assembly 5.

[0043] The seeder 1 is existing technology, which includes traditional functions such as sowing, fertilizing, and covering soil. The mulching mechanism 2 is located at the rear of the seeder 1. That is, when the seeder 1 moves forward to sow potatoes into the soil, the potato seeds are covered by the soil covering plate of the seeder 1, and then the mulching mechanism 2 located at the rear of the seeder 1 covers the soil surface to achieve protection.

[0044] The quick-installation component 4 allows for rapid replacement of the film roll when the roll of film covering 201 is used up. The pressing mechanism 3 compacts the film covering 201 onto the soil surface, ensuring it adheres to the ground. However, when the roll of film covering 201 initially adheres to the ground, it needs to pass under the pressing component 5. Conventionally, this requires manual lifting and then smoothing, a process difficult for a single person and prone to causing the film passing under the pressing component 5 to clump and become tangled, affecting subsequent film laying. Therefore, the lifting and positioning component 6 allows manual lifting of the pressing component 5 above the ground and temporary locking of its position. This facilitates the smooth laying of the film under the pressing component 5, ensuring a flat laying of the film. After the film is laid flat, the lifting and positioning component 6 can be unlocked, allowing the pressing component 5 to firmly press and lay the film.

[0045] The quick-release assembly 4 includes a U-shaped frame 401 mounted on the frame of the seeder 1, and a rotating seat 402 and a quick-release seat 7 mounted on the U-shaped frame 401;

[0046] The rotating seat 402 and the quick-release seat 7 are respectively fixed to both ends of one side of the U-shaped frame 401 by bolts.

[0047] When replacing the roll coating 201, first insert the rotating shaft at one end into the insertion hole of the rotating seat 402, then open the quick-release seat 7, place the rotating shaft at the other end of the roll coating 201 into the slot on the quick-release seat 7, and then close and lock the quick-release seat 7 to achieve quick installation and removal of the roll coating 201.

[0048] The quick-release seat 7 includes a seat body 701 disposed at one end of the U-shaped frame 401, and a snap-fit ​​block 702 is rotatably mounted on the end of the seat body 701 away from the U-shaped frame 401. Matching rotating grooves 703 are provided on the snap-fit ​​block 702 and the seat body 701, and the rotating grooves 703 are rotatably matched with the rotating shaft of the roll film 201.

[0049] A sliding cover 704 is slidably installed on the top of the base 701, and slide strips 705 are provided on both sides of the inner wall of the sliding cover 704. Sliding grooves 706 are provided on the upper ends of both sides of the base 701, and the sliding grooves 706 and slide strips 705 are slidably matched.

[0050] The snap-fit ​​block 702 has mating grooves 707 on both sides, and the mating grooves 707 match the slide bar 705.

[0051] When quickly installing the roll film 201, first insert the shaft at one end of the roll film 201 into the insertion hole of the rotating seat 402, then rotate to open the locking block 702, and then place the shaft at the other end of the roll film 201 into half of the rotating groove 703 on the seat 701. Rotate to close the locking block 702 so that the locking block 702 and the groove on the seat 701 form a complete rotating groove 703. At this time, move the sliding cover 704 toward the locking block 702 so that one end of the slide bar 705 moves from the sliding groove 706 to the mating groove 707 on the locking block 702, thereby preventing the locking block 702 from being rotated open. When quickly disassembling, follow the above steps.

[0052] A return spring 708 is provided inside the sliding groove 706, and the two ends of the return spring 708 respectively abut against one end of the sliding groove 706 and one end of the slide bar 705;

[0053] The top of the sliding cover 704 is provided with a push plate 709.

[0054] The design of the reset spring 708 ensures that the two ends of the slider 705 are located in the docking groove 707 and the sliding groove 706 respectively in the initial state, thereby realizing the locking of the locking block 702. The setting of the push plate 709 makes it easy for the operator to unlock the locking block 702.

[0055] The film pressing assembly 5 includes a T-shaped frame 501 rotatably mounted on the I-shaped frame 301, and a film pressing roller 502 rotatably mounted on the end of the T-shaped frame 501 away from the I-shaped frame 301.

[0056] The lifting positioning assembly 6 includes a pull rod 601 rotatably mounted on a T-shaped frame 501, and a hand grip 602 disposed at the top of the pull rod 601.

[0057] By pulling the handle 602 upwards, the pull rod 601 is moved upwards, causing the T-shaped frame 501 to rotate, thereby raising the pressure roller 502.

[0058] The I-shaped frame 301 has a strip groove 302, and the tie rod 601 moves through the strip groove 302.

[0059] The lifting positioning component 6 also includes a hook block 603 located at the top of the I-shaped frame 301 and at one end of the strip groove 302, and a hanging ring 604 arranged in a linear array on the side of the pull rod 601 near the hook block 603.

[0060] After the pull rod 601 is raised to the height of the film pressing roller 502, it is engaged with the hanging ring 604 on one side of the pull rod 601 and the hanging block 603 on the I-shaped frame 301, thereby achieving temporary position locking, so that the operator can lay the film flat.

[0061] A guide hole 303 is provided at one end of the I-shaped frame 301 away from the roll film 201, and the guide hole 303 is connected to the strip groove 302. A top rod 8 is movably inserted into the guide hole 303, and one end of the top rod 8 extends through the guide hole 303 into the inside of the strip groove 302 and abuts against the linear array of hanging rings 604 on one side of the pull rod 601. The other end of the top rod 8 extends through the guide hole 303 to the outside of the I-shaped frame 301, and a retaining ring 801 is provided at the end of the top rod 8 extending through the guide hole 303 to the outside of the I-shaped frame 301. A compression spring 9 that is sleeved with the top rod 8 is provided on the side of the retaining ring 801 away from the I-shaped frame 301.

[0062] A stop 10 is provided at one end of the I-shaped frame 301 away from the roll film 201, and the two ends of the compression spring 9 abut against the stop ring 801 and the stop 10 respectively. A through hole 1001 is provided on the stop 10, and the through hole 1001 and the top rod 8 are movably inserted into it.

[0063] In the initial state, the compression spring 9 pushes the pull rod 601 to turn the strip groove 302 away from the end of the hook block 603, so that the pressure roller 502 moves up and down with the ground when it moves forward, and the hanging ring 604 cannot be engaged with the hook block 603. The end of the top rod 8 that abuts against the hanging ring 604 is spherical, and the diameter of the top rod 8 is larger than the spacing between the linear array hanging rings 604, so that the top rod 8 can still move when it abuts against the linear array hanging rings 604.

[0064] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
