Description

Technical Field

[0001] This utility model belongs to the technical field of soil turning devices, specifically a soil turning device for vegetable planting with adjustable depth. Background Technology

[0002] Turning the soil is a crucial preliminary step in vegetable cultivation, directly affecting soil aeration and root growth. In actual cultivation, the soil in some plots (such as idle vegetable gardens and newly reclaimed vegetable fields in the suburbs) often contains gravel with a diameter of 3-10cm. When turning the soil shallowly, the gravel can easily obstruct the shovel from entering the soil, resulting in insufficient local turning depth. When turning the soil deeply, the gravel can easily collide with the shovel head. Small motorized soil turning equipment and the shovel body are mostly rigidly connected, which can easily cause the shovel head to deform and the frame to vibrate when impacted by gravel. When adapting to multi-variety rotation scenarios, this is both time-consuming and labor-intensive, and increases equipment maintenance costs.

[0003] Farmers need to manually remove stones first, and then adjust the equipment to turn the soil at an adjustable depth. This double operation doubles the labor intensity and affects the planting time of vegetables. Therefore, a soil turning device for vegetable planting with adjustable depth is proposed to address the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, a soil-turning device for vegetable cultivation with adjustable depth is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the soil turning device for vegetable planting with adjustable depth according to this utility model includes a mounting frame; an electric telescopic rod is fixedly connected to the top of the mounting frame, and the output end of the electric telescopic rod passes through the mounting frame and is fixedly connected to a mounting plate; The mounting plate is equipped with a protective mechanism, which includes a positioning groove on one side of the mounting plate. A fixing rod is fixedly connected to the inner top wall of the positioning groove via a connecting block. A spring is sleeved on the outer wall of the fixing rod. A transmission frame is slidably connected to the outer wall of the fixing rod. A transmission block is slidably connected inside the transmission frame. The bottom end of the transmission block extends out of the transmission frame and is fixedly connected to a soil-turning shovel. A limit groove is formed on the inner side wall of the transmission frame. A limit block is slidably connected inside the limit groove. A limit ring is fixedly connected to the inner side wall of the limit groove. A plug-in block is fixedly connected to one end of the limit block near the limit ring. The other end of the plug-in block extends out of the limit groove and is inserted into a slot on one side of the transmission block. A second spring is sleeved on the outer wall of the plug-in block inside the limit groove. A fixing groove is formed on the inner side wall of the positioning groove. With the setting of the protective mechanism, when the soil-turning shovel encounters a large stone, it can automatically detach from the mounting plate, avoiding continuous pressure on the stone by the soil-turning shovel and causing deformation and damage to the soil-turning shovel.

[0006] Preferably, a fixing ring is fixedly connected to the inner side wall of the fixing groove, and a wear-resistant layer is provided on the outer wall of the limiting block. By setting the fixing ring, it is convenient to move and limit the transmission frame at the same time as releasing the limiting of the transmission block. This avoids the situation where the operator drops the soil turning shovel and needs to put it back, but the transmission frame cannot be pushed due to the excessive pressure of the first spring, which would affect the soil turning.

[0007] Preferably, the bottom of the fixed ring is provided with an auxiliary groove, and the inner sidewall of the auxiliary groove is rotatably connected to an auxiliary roller via a rotating shaft. The dual shafts of the auxiliary groove and the auxiliary roller can facilitate the reduction of resistance when moving the limiting block.

[0008] Preferably, threaded holes are provided on both sides of the mounting bracket, and bolts are threaded into the threaded holes. One end of the bolt extends out of the threaded hole and is inserted into a positioning hole provided on one side of the mounting plate. The bolt holes, bolts, and positioning holes facilitate the movement and positioning of the mounting plate, and prevent the mounting plate from being temporarily limited if the electric telescopic rod is damaged.

[0009] Preferably, auxiliary frames are fixedly connected to both sides of the mounting bracket, and a baffle is rotatably connected to one side of the auxiliary frame via a pivot. The auxiliary frame and the baffle can be used to cover the bolts and threaded holes.

[0010] Preferably, both sides of the mounting frame are rotatably connected to support wheels via a pivot, and one side of the mounting frame is provided with scale lines. The support wheels facilitate the movement of the mounting frame.

[0011] Preferably, a traction ring is fixedly connected to one side of the mounting frame, and the inner wall of the traction ring is provided with a wear-resistant layer. The traction ring facilitates connection with a tractor, so as to move the device.

[0012] The beneficial effects of this utility model are: This utility model provides a depth-adjustable soil-turning device for vegetable planting. Through the installation of a protective mechanism, the turning shovel automatically detaches from the mounting plate when it encounters a large stone, preventing continuous pressure on the stone and thus avoiding deformation and damage. The tractor or towing device's towing hook is inserted into the towing ring and fixed. The electric telescopic rod is activated to adjust the height of the turning shovel using the mounting plate. The tractor is then started to drive the device for turning wasteland. During the turning process, if the turning shovel encounters a large stone, its movement is obstructed and it is subjected to pressure. The turning shovel applies pressure to the transmission frame through the transmission block until it exceeds a set pressure threshold. At this point, one end of the limiting block inserts into the fixing groove, and the end of the plug-in block located in the slot moves out, releasing the movement limit on the transmission block. The turning shovel and transmission block detach from the mounting plate and fall to the ground, preventing deformation of the turning shovel due to excessive pressure. Attached Figure Description

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Specific implementation examples are given below.

[0017] Please see Figures 1-4 This utility model provides a soil turning device for vegetable planting with adjustable depth, including a U-shaped mounting frame 1; an electric telescopic rod 2 is fixedly connected to the top of the mounting frame 1, and the output end of the electric telescopic rod 2 passes through the mounting frame 1 and is fixedly connected to a rectangular mounting plate 3; Both sides of the mounting bracket 1 are provided with threaded holes, and bolts 7 are threadedly connected in the threaded holes. One end of the bolt 7 extends out of the threaded hole and is inserted into the positioning hole 8 opened on one side of the mounting plate 3. The setting of the bolt 7 hole, bolt 7 and positioning hole 8 can facilitate the movement and positioning of the mounting plate 3, and avoid the inability to temporarily limit the mounting plate 3 when the electric telescopic rod 2 is damaged. Auxiliary frames 9 are fixedly connected to both sides of the mounting bracket 1. A baffle is rotatably connected to one side of the auxiliary frame 9 via a rotating shaft. The auxiliary frame 9 and the baffle can cover the bolt 7 and the threaded hole. Both sides of the mounting frame 1 are rotatably connected to support wheels 10 via rotating shafts. One side of the mounting frame 1 is provided with scale lines. The support wheels 10 facilitate the movement of the mounting frame 1. A traction ring 11 is fixedly connected to one side of the mounting frame 1. The inner wall of the traction ring 11 is provided with a wear-resistant layer. The traction ring 11 facilitates connection with a tractor to move the device. The mounting plate 3 is provided with a protective mechanism 4. The protective mechanism 4 includes five rectangular positioning slots 41 that are equidistantly distributed on one side of the mounting plate 3. The positioning slots 41 penetrate the mounting plate 3. The inner top wall of the positioning slots 41 is fixedly connected to a fixing rod 43 by connecting blocks. There are two connecting blocks, and the two connecting blocks are symmetrically distributed with respect to the fixing rod 43. The outer wall of the fixing rod 43 is fitted with a first spring 44. The outer wall of the fixing rod 43 is slidably connected to a transmission frame 45 with a rectangular slot at the bottom. The transmission frame 45 is slidably connected to a transmission block 46. The bottom end of the transmission block 46 extends out of the transmission frame 45 and is fixedly connected to a soil turning shovel 47. Both sides of the inner wall of the transmission frame 45 are provided with limiting grooves that penetrate the transmission frame 45. Limiting blocks 48 are slidably connected in the limiting grooves. Limiting rings 49 are fixedly connected to the inner side wall of the limiting grooves. A rectangular plug-in block is fixedly connected to one end of the limiting block 48 near the limiting ring 49. The plug-in block is adapted to the rectangular inner ring of the limiting ring 49. The limiting ring 49 moves and limits the limiting block, but does not move and limit the plug-in block. The other end of the plug-in block extends out of the limiting groove after passing through the limiting ring 49 and is inserted into the slot 42 opened on one side of the transmission block 46. A second spring 410 is sleeved on the outer wall of the plug-in block located in the limiting groove. A fixing groove 411 is opened on the inner side wall of the positioning groove 41. A rectangular stop is fixedly connected to the inner wall of the transmission frame 45. It should be noted that the stop is located between the transmission block 46 and the fixing groove 411. The stop further limits the transmission block 46 and reduces the pressure on the two plug-in blocks. With the setting of the protective mechanism 4, when the soil turning shovel 47 encounters a large stone, it can automatically detach from the mounting plate 3, avoiding the soil turning shovel 47 from continuously applying pressure to the stone and causing deformation and damage to the soil turning shovel 47. A fixing ring 5 is fixedly connected to the inner wall of the fixing groove 411, and a wear-resistant layer is provided on the outer wall of the limiting block 48. By setting the fixing ring 5, it is convenient to release the limiting of the transmission block 46 and move the transmission frame 45 to limit its movement. This prevents the operator from dropping the soil turning shovel 47 and needing to put it back in, as the pressure of the first spring 44 is too large and the transmission frame 45 cannot be pushed, thus affecting the soil turning process. An auxiliary groove is provided at the bottom of the fixed ring 5. An auxiliary roller 6 is rotatably connected to the inner side wall of the auxiliary groove via a rotating shaft. The dual shafts of the auxiliary groove and the auxiliary roller 6 can help reduce the resistance when moving the limit block 48.

[0018] Based on the above structure, this application includes the following implementation process: Insert the tractor or traction equipment's towing hook into the towing ring 11 and secure it with bolt 7. The specific securing method is a mature existing technology and will not be elaborated further. Then, depending on the required depth of soil turning, first flip it open for easy access. Reach inside the auxiliary frame 9 and rotate bolt 7 so that one end of bolt 7 located in the positioning hole 8 moves out. Start the electric telescopic rod 2 to drive the mounting plate 3 to adjust its height, that is, adjust the height of the soil turning shovel 47. After adjustment, reverse bolt 7 so that one end of bolt 7 is inserted into the corresponding positioning hole 8, strengthening the movement limit of the mounting plate 3. Then, start the tractor or traction equipment to turn the wasteland before vegetable planting. It should be noted that the power supply for the electric telescopic rod 2 can be provided by the battery installed and fixed on the mounting frame 1, and the two are electrically connected by wires. During the soil turning process, if the soil turning shovel 47 encounters a large stone, the stone will prevent the soil turning shovel 47 from moving. At this time, the pressure on the soil turning shovel 47 gradually increases. At this time, the transmission block 46 moves and is limited by two plug-in blocks with one end inserted into the slot 42. The end of the limiting block 48 away from the plug-in block is pressed by the inner wall of the positioning groove 41 and cannot move away from the plug-in block. The soil turning shovel 47 presses the transmission frame 45 through the transmission block 46. The transmission frame 45 presses the first spring 44, causing the transmission frame 45 to move towards the fixed groove 411. It should be noted that the first spring 44 is located between the transmission frame 45 and the fixed groove 411. As the pressure on the turning shovel 47 gradually increases, the transmission frame 45 moves synchronously towards the fixed groove 411 until the pressure threshold is exceeded. At this point, the transmission frame 45 moves to the position corresponding to the fixed groove 411, and the resistance to the movement of the limiting block 48 disappears. Under the pressure of the second spring 410, the limiting block 48 drives the insertion block to move towards the fixed groove 411. One end of the limiting block 48 is inserted into the fixing ring 5 in the fixed groove 411. The fixing ring 5 limits the movement of the limiting block 48, thereby limiting the movement of the transmission frame 45, so as to facilitate the subsequent... As the soil-turning shovel 47 is reinstalled, the end of the plug block located in the slot 42 moves out, releasing the movement limit on the transmission block 46. At this time, under the weight of the transmission block 46 and the soil-turning shovel 47 themselves, the soil-turning shovel 47 and the transmission block 46 detach from the mounting plate 3 and fall to the ground, thus preventing the soil-turning shovel 47 from deforming due to excessive pressure. It should be noted that the pressure value of the first spring 44 can be set according to the actual situation, that is, it should be ensured that it will not be accidentally triggered by large soil clods and small stones, so that the soil-turning shovel 47 will only be triggered to detach when it encounters a stone exceeding the set weight. When the driver notices that the tilling shovel 47 has fallen off, he should pick it up and reinsert the transmission block 46 into the transmission frame 45. At the same time, he should push one end of the two limiting blocks 48 located in the fixed ring 5, causing the limiting blocks 48 to disengage from the fixed ring 5, thus releasing the movement limitation on the limiting blocks 48 and the transmission frame 45. Simultaneously, one end of the insertion block should be reset and inserted into the slot 42. Then, the tilling shovel 47 should be quickly released. Under the strong pressure of the first spring 44, the transmission frame 45 will drive the tilling shovel 47 to reset through the transmission block 46, so that it is parallel to the other tilling shovels 47 that have not disengaged. The driver can then continue to drive the tractor to move the device to carry out tilling operations until all the wasteland has been tilled.
