Description

Technical Field

[0001] This utility model relates to the field of yam harvesting technology, specifically to a yam harvesting and soil loosening tool. Background Technology

[0002] Yam, belonging to the Dioscoreaceae family, has its dried rhizome used as a traditional Chinese medicine. The yam tuber is fleshy and thick, slightly cylindrical, and grows vertically. Its outer skin is grayish-brown and has fibrous roots. In traditional Chinese medicine, yam is believed to have the effects of tonifying the spleen and stomach, promoting body fluid production and benefiting the lungs, and tonifying the kidneys and astringing essence. The harvesting and processing method involves digging up the yam after the stems and leaves have withered in winter, cutting off the root head, washing away the soil, removing the outer skin and fibrous roots, and then drying it after fumigating it with sulfur.

[0003] A soil loosener is an agricultural machinery tool mainly used to loosen the soil during agricultural cultivation. In the process of harvesting yams, the soil around the yams is prone to hardening and clumping, making it difficult to pick the yams directly. A soil loosener is needed to loosen the soil around the yams to facilitate harvesting.

[0004] Utility model patent CN220476245U discloses a soil ripper, including a tube body with an adjustment mechanism installed inside. A positioning mechanism is fixedly connected to the top of the tube body, and folding mechanisms are provided on both sides of the positioning mechanism. The adjustment mechanism includes a guide rod, a threaded rod, a movable plate, and a connecting rod. The threaded rod is rotatably connected to the middle position inside the tube body, and the movable plate is slidably connected to the surface of the guide rod. Connecting rods are fixedly connected to both sides of the bottom of the movable plate. The device utilizes a transmission ring, transmission rod, positioning structure, and adjustment mechanism in conjunction. Rotating the transmission ring causes the threaded rod to rotate, thereby driving the movable plate to move up and down. The movement of the movable plate drives the fixedly connected movable rod to move in the same direction, thus adjusting the position of the shovel and changing its overall length. Releasing the pressing plate then fixes the overall length of the shovel, making it suitable for users of different heights.

[0005] The existing technology still has some problems: 1. The soil loosening tool is long and slender, making it difficult to carry. It can only be carried by hand. When loosening soil, the hands are already very tired. In addition, the area where soil is loosened is usually in farmland, and it needs to be carried back and forth, which puts a great burden on the operator's wrists and easily leads to fatigue.

[0006] 2. The shovel of this soil loosener cannot be replaced. Because the shovel is prone to hitting stones or other hard objects in the field when loosening the soil, the sharp part of the shovel will be damaged and dulled after long-term use, resulting in a decrease in soil loosening efficiency.

[0007] 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

[0008] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a yam harvesting and soil loosening tool.

[0009] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0014] A dismantling device, comprising a clamping plate, wherein the dismantling device dismantles the loosening shovel by moving the clamping plate.

[0015] As an improvement, foot pedals are fixedly connected to both sides of the lower part of the support rod, and handles are fixedly connected to both sides of the upper part of the second support rod.

[0016] As an improvement, the second support rod is hollow inside, the upper part of the first support rod is slidably connected to the second support rod, and a number of evenly distributed limiting holes are opened on one side of the first support rod. The lower part of the second support rod is threaded with a bolt one near the limiting hole, and the end of the bolt one near the limiting hole extends through the second support rod and into the limiting hole.

[0017] As an improvement, the buffer assembly is disposed at the upper and lower parts of the front end of the second support rod. The buffer assembly includes a mounting frame, which is fixedly connected to the second support rod. The upper and lower ends of the inner wall of the mounting frame are fixedly connected to a fixing rod. A buffer block is slidably connected to the fixing rod. Buffer springs are sleeved on the outer sides of the upper and lower parts of the fixing rod. The two ends of the buffer springs are fixedly connected to the buffer block and the inner wall of the mounting frame, respectively.

[0018] As an improvement, a connecting block is fixedly connected to the front end of the buffer block, and both sides of the connecting block are slidably connected to the inner wall of the mounting frame. The upper and lower ends of the shoulder strap are respectively rotatably connected to the upper and lower connecting blocks.

[0019] As an improvement, the disassembly device further includes a mounting block, which is fixedly connected to the lower end of the support rod. A cavity is opened on one side of the mounting block, and a bolt is threaded to the rear end of the mounting block. The front end of the bolt extends through the mounting block into the cavity and is rotatably connected to a push block.

[0020] As an improvement, the mounting block has a cavity two on the side away from cavity one to accommodate the connecting column.

[0021] As an improvement, a wedge block is fixedly connected to one end of the moving rod near the pushing block, the wedge block and the pushing block push against each other, a telescopic spring is sleeved on the outside of the moving rod, the two ends of the telescopic spring are fixedly connected to the wedge block and the partition plate respectively, and the clamping plate is fixedly connected to the end of the moving rod away from the wedge block.

[0022] The advantages of this utility model compared with the prior art are as follows: 1. The operator carries the device on his back by carrying it on his back, which relieves hand fatigue. During the operator's carrying and walking, the buffer component allows the device to buffer and unload to a certain extent with the force of gravity and the elastic deformation of the buffer spring, reducing the burden on the operator.

[0023] 2. When the loosening shovel is severely worn, the loosening shovel can be disassembled and installed by moving the clamping plate. This is simple and quick, and avoids affecting the loosening efficiency, which would otherwise slow down the yam harvesting. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] Combined with appendix Figures 1-5 A yam harvesting and soil loosening tool mainly includes: a soil loosening shovel 1, a support rod 3, a carrying device 5, and a disassembly device 7. The soil loosening shovel 1 has a connecting column 2 fixedly connected to its upper end. The support rod 3 has a support rod 4 on its upper part. Foot pedals 9 are fixedly connected to both sides of the lower part of the support rod 3. Handles 26 are fixedly connected to both sides of the upper part of the support rod 4. By stepping on the foot pedal 9 with one foot and holding the handles 26 with both hands, it is convenient to dig and shovel the hard soil around the yam.

[0032] Then, the support rod 2 4 is hollow inside, and the upper part of the support rod 1 3 is slidably connected to the support rod 2 4. Several evenly distributed limiting holes 10 are opened on one side of the support rod 1 3. The lower part of the support rod 2 4 near the limiting hole 10 is threaded with a bolt 11. The end of the bolt 11 near the limiting hole 10 passes through the support rod 2 4 and extends into the limiting hole 10. By rotating the bolt 11, it is moved away from the limiting hole 10 until it is disengaged from the limiting hole 10. Then, the length of the support rod 1 3 and the support rod 2 4 is adjusted. After the adjustment is completed, the bolt 11 is rotated in the opposite direction to move it towards the limiting hole 10 until it extends into it, thus completing the length fixation, which is convenient for people of different heights to use.

[0033] Next, the carrying device 5 includes a carrying strap 6 and a buffer assembly. The buffer assembly is used to cushion the movement of the carrying strap 6. The buffer assembly is located at the upper and lower parts of the front end of the support rod 4. The buffer assembly includes a mounting frame 12, which is fixedly connected to the support rod 4. The upper and lower ends of the inner wall of the mounting frame 12 are fixedly connected to a fixing rod 13. A buffer block 14 is slidably connected to the fixing rod 13. Buffer springs 15 are sleeved on the upper and lower outer sides of the fixing rod 13. The two ends of the buffer springs 15 are fixedly connected to the buffer block 14 and the inner wall of the mounting frame 12, respectively. A connecting block 16 is fixedly connected to the front end of the buffer block 14. Both sides of the connecting block 16 are slidably connected to the inner wall of the mounting frame 12. The upper and lower ends of the carrying strap 6 are rotatably connected to the upper and lower connecting blocks 16, respectively.

[0034] After the yams are harvested, the operator can carry the device on their back using the shoulder strap 6, freeing their hands and making it easy to pick up and drop the yams. As the operator walks, the device will move up and down to a certain extent. At this time, the buffer block 14 and the connecting block 16 on it will start to compress the buffer spring 15, causing it to undergo a certain degree of elastic deformation. In the process of repeated contraction and expansion, it absorbs some of the buffering force and the weight of the equipment itself, which reduces the burden on the operator's back.

[0035] Specifically, the disassembly device 7 includes a clamping plate 8, which is arc-shaped and cooperates with the connecting column 2. The disassembly device 7 completes the disassembly of the loosening shovel 1 by moving the clamping plate 8. The disassembly device 7 also includes an installation block 17, which is fixedly connected to the lower end of the support rod 3. A cavity 18 is opened on one side inside the installation block 17. A bolt 19 is threadedly connected to the rear end of the installation block 17. The front end of the bolt 19 passes through the installation block 17 and extends into the cavity 18, and is rotatably connected to a push block 20.

[0036] Furthermore, the mounting block 17 has a cavity 21 on the side away from the cavity 18 to accommodate the connecting column 2. The upper end of the connecting column 2 extends through the mounting block 17 into the cavity 21. A partition 22 is fixedly connected to the side of the cavity 18 near the cavity 21. A moving rod 23 is slidably connected through the middle of the partition 22. The moving rod 23 is a rectangular rod that moves horizontally. A wedge block 24 is fixedly connected to the end of the moving rod 23 near the push block 20. Both the wedge block 24 and the push block 20 have mutually cooperating inclined surfaces. The wedge block 24 and the push block 20 push against each other. A telescopic spring 25 is sleeved on the outside of the moving rod 23. The two ends of the telescopic spring 25 are fixedly connected to the wedge block 24 and the partition 22, respectively. A clamping plate 8 is fixedly connected to the end of the moving rod 23 away from the wedge block 24.

[0037] When the loosening shovel 1 is severely worn after long-term use, rotating bolt 219 causes the push block 20 to move backward. The wedge block 24 and the push block 20 gradually disengage from the push block. The telescopic spring 25 pushes the wedge block 24 away from the cavity 21, and the clamping plate 8 moves towards the cavity 18, disengaging from the clamping of the connecting column 2 and releasing its limit. The loosening shovel 1 can then be removed from the cavity 21 for replacement, which is simple and quick. When installation is required, the connecting column 2 is placed in the cavity 21, and bolt 219 is rotated in the opposite direction. The push block 20 pushes the wedge block 24, and the moving rod 23 moves towards the cavity 21. The clamping plate 8 clamps and fixes the connecting column 2. During installation and disassembly, the push block 20 is frustum-shaped, and the wedge block 24 and the push block 20 always maintain the push and will not disengage. When loosening soil, bolt 219 and mounting block 17 do not contact the ground.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
