Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery and equipment, and specifically relates to an automatic separating and transplanting device for Codonopsis pilosula seedlings. Background Technique

[0002] At present, Codonopsis pilosula is mainly planted by the method of "direct seeding and raising seedlings + transplanting and planting". The transplanting method is mainly semi-automatic transplanting. The furrow opener opens the seedling groove, and through manual assistance for placing the seedlings, the seedlings are put into the seedling groove by the conveying device, and at the same time, soil covering and film mulching operations are carried out.

[0003] Since the transplanting of Codonopsis pilosula currently usually requires separating the Codonopsis pilosula seedlings first, then placing them on the conveyor belt. Through the conveyance of the conveyor belt, they are clamped by the seedling clamping disc and brought into the soil to achieve the purpose of planting. However, manually separating the Codonopsis pilosula seedlings and placing them on the conveyor belt results in low work efficiency and high labor intensity for the planting of Codonopsis pilosula seedlings. In view of the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an automatic separating and transplanting device for Codonopsis pilosula seedlings, including an overall support. The overall support further includes an auxiliary wheel rotatably connected to the inner wall of the overall support. A first fixed support is fixedly connected to the top of the overall support. A second fixed support is fixedly connected to the outer wall of the overall support. A third fixed support is fixedly connected to the top of the overall support. A ditch-digging and anti-overflow component is fixedly connected to the bottom of the overall support;

[0005] A power transmission mechanism, the power transmission mechanism includes a motor fixedly connected to the bottom of the second fixed support. A pulley is fixedly connected to the outer wall of the motor. A first belt is sleeved on the outer wall of the pulley. A first rotating rod is rotatably connected to the inner wall of the overall support. The first belt is sleeved on the outer wall of the first rotating rod. A worm is fixedly connected to the outer wall of the first rotating rod. A worm gear rod is meshed and connected to the outer wall of the worm. The outer wall of the worm gear rod is rotatably connected to the inner wall of the third fixed support. A second belt is sleeved on the outer wall of the worm gear rod. A cleaning and extrusion component is fixedly connected to the outer wall of the first rotating rod;

[0006] Separation and conveying mechanism. The separation and conveying mechanism includes a feeding trough fixedly connected to the top of the overall bracket. A second rotating rod is rotatably connected to the inner wall of the feeding trough. A first gear is fixedly connected to the outer wall of the second rotating rod. A second gear is meshed with the outer wall of the first gear. A transmission guide wheel is fixedly connected to the inner wall of the second gear. A transmission belt is sleeved on the outer wall of the transmission guide wheel. A second belt is sleeved on the outer wall of the transmission guide wheel. A partition is fixedly connected to the outer wall of the feeding trough. The outer wall of the partition is fixedly connected to the outer wall of the first fixed bracket. A spring bump is slidably connected to the inner wall of the second rotating rod. A protruding tooth is fixedly connected to the outer wall of the transmission belt. By using the characteristic that the spring bump can be clamped between the Codonopsis pilosula seedlings when the second rotating rod rotates, a motor is set. When the motor is powered on and running, it drives the pulley to rotate, and then through the transmission of the first belt, the first rotating rod rotates synchronously. When the first rotating rod rotates, the worm drives the worm gear rod to rotate together, and then through the transmission of the second belt, the transmission guide wheel is driven to rotate. When the transmission guide wheel rotates, the second rotating rod is driven to rotate through the second gear and the first gear. After the bundled Codonopsis pilosula seedlings are put into the feeding trough, they slide down along the inclined surface of the side wall of the feeding trough to the second rotating rod. When the second rotating rod rotates, it can drive the spring bump to be clamped between the Codonopsis pilosula and the Codonopsis pilosula, and then the two are separated during the rotation. At the same time, when the spring bump directly contacts the Codonopsis pilosula seedlings, the spring bump will be compressed and contracted inward to avoid squeezing the Codonopsis pilosula seedlings during rotation and causing damage to them. After the separated Codonopsis pilosula seedlings are pushed away from the feeding trough, they fall downward onto the transmission belt. Through the blocking of the partition, the Codonopsis pilosula seedlings are clamped on the protruding teeth, preventing them from rolling directly downward, which affects the subsequent clamping and planting of the Codonopsis pilosula seedlings. At the same time, it also prevents two Codonopsis pilosula seedlings from falling simultaneously, resulting in the situation where neither of them is clamped by the protruding teeth. Through the operation of the above components, the bundled Codonopsis pilosula seedlings can be automatically separated into individual Codonopsis pilosula seedlings, which is convenient for the subsequent clamping and planting of the Codonopsis pilosula seedlings, improving the working efficiency during planting, and avoiding the inconvenience of manually separating the bundled Codonopsis pilosula seedlings and then placing them on the transmission belt, which affects the planting efficiency.

[0007] Preferably, the cleaning and extrusion assembly includes a first seedling clamping plate fixedly connected to the outer wall of the first rotating rod, an elastic sponge fixedly connected to the outer wall of the first rotating rod, a second seedling clamping plate fixedly connected to the outer wall of the first rotating rod, and the outer wall of the second seedling clamping plate is fixedly connected to the outer wall of the elastic sponge. When the first rotating rod rotates, it can drive the first seedling clamping plate, the elastic sponge and the second seedling clamping plate to rotate synchronously, so that the Codonopsis pilosula seedlings falling between the first seedling clamping plate and the elastic sponge are inserted into the soil under the continuous rotation of the first seedling clamping plate and the elastic sponge, thereby achieving the purpose of planting Codonopsis pilosula seedlings.

[0008] Preferably, the cleaning and squeezing assembly further includes an arc-shaped block fixedly connected to the outer wall of the overall bracket. A connecting rod is fixedly connected to the outer wall of the overall bracket. A sliding rod is slidably connected to the inner wall of the first seedling clamping plate. When the first seedling clamping plate rotates, the sliding rod is synchronously driven to move. When the first seedling clamping plate drives the sliding rod to move into contact with the arc-shaped block, the sliding rod will be squeezed by the arc-shaped block and contract, driving the subsequent components to clamp the Codonopsis pilosula seedlings.

[0009] Preferably, the cleaning and squeezing assembly further includes a fixing block fixedly connected to the outer wall of the sliding rod. The outer wall of the fixing block is slidably connected to the inner wall of the first seedling clamping plate. A telescopic spring is fixedly connected to the outer wall of the sliding rod. Using the above-mentioned characteristic that the first rotating rod rotates continuously, a first seedling clamping plate is provided. When the first rotating rod rotates, the first seedling clamping plate and the elastic sponge are synchronously driven to rotate. When the first seedling clamping plate rotates, the sliding rod is driven to move. When the sliding rod moves into contact with the arc-shaped block, the sliding rod is pressed and moves towards the elastic sponge, driving the fixing block to move synchronously. At this time, the Codonopsis pilosula seedlings moving downward along the conveyor belt will fall between the fixing block and the elastic sponge, and then be clamped by the outward-moving fixing block and elastic sponge. When the first seedling clamping plate rotates downward, it is inserted into the soil. After the sliding rod loses contact with the arc-shaped block, the sliding rod drives the fixing block to move under the action of the telescopic spring, and the Codonopsis pilosula seedlings lose clamping and thus fall into the soil to achieve the purpose of planting. When the first seedling clamping plate continues to rotate, due to the fixing block contracting inward under the action of the telescopic spring, when it rotates to the fixed scraper, the outer surface of the fixing block will contact the fixed scraper, and the soil on the fixing block will be scraped and removed. This is to prevent the distance between the fixing block and the elastic sponge from decreasing after the soil adhered to the fixing block caking, so that the Codonopsis pilosula seedlings may not be able to fall between the two, and thus cannot be clamped, affecting the planting of the Codonopsis pilosula seedlings. Or after the distance between the fixing block and the elastic sponge decreases, since the moving distance of the fixing block remains unchanged, the clamping force on the Codonopsis pilosula seedlings becomes larger, causing damage to the Codonopsis pilosula seedlings during clamping and affecting the subsequent survival rate.

[0010] Preferably, the cleaning and extrusion assembly further includes a fixed scraper fixedly connected to the outer wall of the connecting rod. A spring scraper is slidably connected to the inner wall of the connecting rod. The outer wall of the spring scraper is slidably connected to the outer wall of the elastic sponge. According to the above description, when the first rotating rod rotates, it drives the elastic sponge and the second seedling clamping plate to rotate. When the elastic sponge rotates continuously, it will continuously contact the spring scraper. Due to the action of the spring, the spring scraper will closely adhere to and squeeze the elastic sponge, causing the elastic sponge to be scraped and squeezed during continuous rotation, so that the residual sticky soil impurities on the elastic sponge are scraped off. At the same time, due to the extrusion of the spring scraper, most of the water in the elastic sponge can be squeezed out. To avoid the influence of the water absorption characteristics of the sponge, when there is more water in the soil and after working for a period of time, the elastic sponge will absorb more water. When there is more water in the elastic sponge, it may affect the resilience of the elastic sponge, affecting the clamping of Codonopsis pilosula seedlings. At the same time, when the elastic sponge absorbs more water, its weight will also increase, thereby increasing the burden on the motor.

[0011] Preferably, the ditch-digging and anti-overflow assembly includes a conical plate fixedly connected to the bottom of the overall bracket. A third rotating rod is rotatably connected to the inner wall of the conical plate. A pressure-receiving plate is fixedly connected to the bottom of the third rotating rod. The outer wall of the pressure-receiving plate is rotatably connected to the inner wall of the conical plate. Due to the conical design of the front of the conical plate, when the traction device drives the transplanting device to move forward, the conical plate will dig a ditch and create a groove in the soil to facilitate the subsequent planting of Codonopsis pilosula seedlings. When creating the groove, the squeezed soil will move from the middle of the conical plate to both sides. When the soil moves to both sides, it will push the pressure-receiving plate to rotate.

[0012] Preferably, the ditch-digging and anti-overflow assembly further includes a conveyor belt rotatably connected to the outer wall of the third rotating rod. The outer wall of the conveyor belt is slidably connected to the inner wall of the conical plate. The outer wall of the conveyor belt is fixedly connected to a fixing plate. The outer wall of the fixing plate is slidably connected to the inner wall of the conical plate. Utilizing the characteristic that the traction device pulls the transplanting device forward, a conical plate is provided. When the device moves forward, the conical plate can dig a ditch and create a groove in the soil. While digging the ditch and creating the groove, the soil will also accumulate more and more and move from the middle of the conical plate to both sides. When the soil moves to both sides, it will push the pressure-receiving plate to rotate. When the pressure-receiving plate rotates, it drives the conveyor belt and the fixing plate to rotate through the third rotating rod. When the fixing plate rotates, it can drive the soil gradually bulging in the middle of the conical plate to both sides, preventing the soil gradually bulging in the middle of the conical plate from falling behind the conical plate during continuous forward movement, so that the ditch dug in the soil does not reach the specified depth and there is more soil in the ditch. When clamping and inserting Codonopsis pilosula seedlings, the Codonopsis pilosula seedlings will contact the soil too much, causing the Codonopsis pilosula seedlings to bend or even break excessively during planting, thereby affecting the growth and survival rate of Codonopsis pilosula seedlings.

[0013] Preferably, the trench anti-overflow component further includes an auxiliary guide wheel rotatably connected to the inner wall of the conical plate. The outer wall of the auxiliary guide wheel is rotatably connected to the inner wall of the conveyor belt. A fixed support four is fixedly connected to the outer wall of the overall support. A rolling wheel is rotatably connected to the outer wall of the fixed support four. The auxiliary guide wheel makes the conveyor belt rotate more smoothly, avoiding the situation of being blocked and stuck midway. When the overall equipment moves forward, the fixed support four drives the rolling wheel to rotate. When the rolling wheel rotates, the soil accumulated on both sides is brought into the dug trench for soil covering operation, ensuring that the Codonopsis pilosula seedlings are covered by soil.

[0014] The present invention has the following beneficial effects:

[0015] (1) When the rotating rod two rotates in the present invention, due to the spring bump being able to be stuck between the Codonopsis pilosula seedlings, a motor is provided. When the motor is powered on and operates, it drives the pulley to rotate. Then, through the transmission of the first belt, the rotating rod one rotates synchronously. When the rotating rod one rotates, the worm drives the worm gear rod to rotate together. Then, through the transmission of the second belt, the transmission guide wheel is driven to rotate. When the transmission guide wheel rotates, the rotating rod two is driven to rotate through the second gear and the first gear. After the bundled Codonopsis pilosula seedlings are placed into the feeding trough, they slide down along the inclined surface of the side wall of the feeding trough to the rotating rod two. When the rotating rod two rotates, it can drive the spring bump to be stuck between the Codonopsis pilosula. Then, during the rotation process, the two are separated. At the same time, when the spring bump directly contacts the Codonopsis pilosula seedlings, the spring bump will be compressed and contract inward to avoid squeezing the Codonopsis pilosula seedlings during rotation and causing damage to them. After the separated Codonopsis pilosula seedlings are pushed away from the feeding trough, they fall downward onto the conveyor belt. Through the blocking of the partition plate, the Codonopsis pilosula seedlings are stuck on the protruding teeth, avoiding directly rolling downward and affecting the subsequent clamping and planting of the Codonopsis pilosula seedlings. At the same time, it also prevents two Codonopsis pilosula seedlings from falling simultaneously, resulting in the situation where neither of them is stuck by the protruding teeth. Through the operation of the above components, the bundled Codonopsis pilosula seedlings can be automatically separated into individual Codonopsis pilosula seedlings, facilitating the subsequent clamping and planting of the Codonopsis pilosula seedlings, improving the working efficiency during planting, and avoiding the inconvenience of manually separating the bundled Codonopsis pilosula seedlings and then placing them on the conveyor belt, which affects the planting efficiency.

[0016] (2)The present invention utilizes the above-mentioned characteristic that the rotating rod rotates continuously, and sets a seedling clamping plate 1. When the rotating rod 1 rotates, it synchronously drives the seedling clamping plate 1 and the elastic sponge to rotate. When the seedling clamping plate 1 rotates, it drives the sliding rod to move. When the sliding rod moves to contact the arc-shaped block, the sliding rod will be pressed to move towards the elastic sponge and drive the fixed block to move synchronously. At this time, the Codonopsis pilosula seedlings moving downward along the conveyor belt will fall between the fixed block and the elastic sponge, and then be clamped by the fixed block and the elastic sponge moving outward. When the seedling clamping plate 1 rotates downward, it is inserted into the soil. After the sliding rod loses contact with the arc-shaped block, the sliding rod drives the fixed block to move under the action of the telescopic spring, and the Codonopsis pilosula seedlings lose the clamping force and thus fall into the soil to achieve the purpose of planting. When the seedling clamping plate 1 continues to rotate, due to the fixed block being contracted inward under the action of the telescopic spring, when it rotates to the fixed scraper, the outer surface of the fixed block will contact the fixed scraper, and the soil on the fixed block will be scraped and removed. This is to prevent the distance between the fixed block and the elastic sponge from decreasing after the soil adhered to the fixed block caked, which may cause the Codonopsis pilosula seedlings to be unable to fall between the two, and thus unable to be clamped, affecting the planting of the Codonopsis pilosula seedlings. Or after the distance between the fixed block and the elastic sponge decreases, since the moving distance of the fixed block remains unchanged, the clamping force on the Codonopsis pilosula seedlings becomes larger, causing damage to the Codonopsis pilosula seedlings during clamping and affecting the subsequent survival rate.

[0017] (3)The present invention utilizes the above-mentioned characteristic that when the rotating rod 1 rotates, it drives the elastic sponge and the seedling clamping plate 2 to rotate. When the elastic sponge rotates continuously, it will continuously contact the spring scraper. Due to the spring scraper being acted on by the spring, it will closely adhere to and squeeze the elastic sponge, causing the elastic sponge to be scraped and squeezed during continuous rotation, so that the residual sticky soil impurities on the elastic sponge are scraped off. At the same time, due to the extrusion of the spring scraper, most of the water in the elastic sponge can be squeezed out. This is to avoid that due to the water absorption characteristic of the sponge, when there is more water in the soil and after working for a period of time, the elastic sponge will absorb more water. When there is more water in the elastic sponge, it may affect the resilience of the elastic sponge, thus affecting the clamping of the Codonopsis pilosula seedlings. At the same time, when the elastic sponge absorbs more water, its weight will also increase, thereby increasing the burden on the motor.

[0018] (4) By taking advantage of the feature that the pulling device pulls the transplanting device forward, the present invention provides a conical plate. When the device moves forward, the conical plate can dig a trench in the soil. While digging the trench, the soil will accumulate more and more, and move from the middle of the conical plate to both sides. When the soil moves to both sides, it will push the pressure-receiving plate to rotate. When the pressure-receiving plate rotates, the conveyor belt and the fixing plate are driven to rotate through the third rotating rod. When the fixing plate rotates, it can drive the soil gradually bulging in the middle of the conical plate to both sides, preventing the soil gradually bulging in the middle of the conical plate from falling behind the conical plate during continuous forward movement, so that the trench dug in the soil does not reach the specified depth and there is more soil in the trench. When clamping and inserting Codonopsis pilosula seedlings, the Codonopsis pilosula seedlings come into contact with the soil too much, causing the Codonopsis pilosula seedlings to bend or even break excessively during planting, thus affecting the growth and survival rate of the Codonopsis pilosula seedlings.

A cleaning and extrusion assembly 4 is fixedly connected to the outer wall of the rotating rod one 204;

[0033] The separating and conveying mechanism 3 includes a feeding chute 301 fixedly connected to the top of the overall bracket 1. A second rotating rod 302 is rotatably connected to the inner wall of the feeding chute 301. A first gear 303 is fixedly connected to the outer wall of the second rotating rod 302. A second gear 304 is meshed with the outer wall of the first gear 303. A transmission guide wheel 305 is fixedly connected to the inner wall of the second gear 304. A transmission belt 306 is sleeved on the outer wall of the transmission guide wheel 305. A second belt 207 is sleeved on the outer wall of the transmission guide wheel 305. A partition plate 307 is fixedly connected to the outer wall of the feeding chute 301. The outer wall of the partition plate 307 is fixedly connected to the outer wall of the first fixed bracket 102. A spring bump 308 is slidably connected to the inner wall of the second rotating rod 302. A protruding tooth 309 is fixedly connected to the outer wall of the transmission belt 306. By using the characteristic that the spring bump 308 can be stuck between the Codonopsis pilosula seedlings when the second rotating rod 302 rotates, a motor 201 is provided. When the motor 201 is powered on and operates, it drives the pulley 202 to rotate. Then, through the transmission of the first belt 203, the first rotating rod 204 rotates synchronously. When the first rotating rod 204 rotates, the worm 205 drives the worm gear rod 206 to rotate together. Then, through the transmission of the second belt 207, the transmission guide wheel 305 is driven to rotate. When the transmission guide wheel 305 rotates, the second rotating rod 302 rotates through the second gear 304 and the first gear 303. After the bundled Codonopsis pilosula seedlings are placed in the feeding chute 301, they slide down along the inclined surface of the side wall of the feeding chute 301 to the second rotating rod 302. When the second rotating rod 302 rotates, it can drive the spring bump 308 to be stuck between the Codonopsis pilosula and the Codonopsis pilosula, and then separate the two during the rotation process.

Through the operation of the above components, the bundled Codonopsis pilosula seedlings can be automatically separated into individual Codonopsis pilosula seedlings, which is convenient for the subsequent clamping and planting of the Codonopsis pilosula seedlings, improving the working efficiency during planting and avoiding the inconvenience of manually separating the bundled Codonopsis pilosula seedlings and then placing them on the transmission belt 306, which affects the planting efficiency.

[0034] Example 2, please refer to Figures 5 - 8, the present invention is an automatic separation and transplanting device for Codonopsis pilosula seedlings. On the basis of Embodiment 1, the cleaning and extrusion assembly 4 includes a first seedling clamping plate 401 fixedly connected to the outer wall of the first rotating rod 204. An elastic sponge 402 is fixedly connected to the outer wall of the first rotating rod 204. A second seedling clamping plate 403 is fixedly connected to the outer wall of the first rotating rod 204. The outer wall of the second seedling clamping plate 403 is fixedly connected to the outer wall of the elastic sponge 402. When the first rotating rod 204 rotates, it can drive the first seedling clamping plate 401, the elastic sponge 402 and the second seedling clamping plate 403 to rotate synchronously, so that the Codonopsis pilosula seedlings falling between the first seedling clamping plate 401 and the elastic sponge 402 are inserted into the soil under the continuous rotation of the first seedling clamping plate 401 and the elastic sponge 402, thereby achieving the purpose of planting Codonopsis pilosula seedlings.

[0035] The cleaning and extrusion assembly 4 further includes an arc-shaped block 404 fixedly connected to the outer wall of the overall bracket 1. A connecting rod 405 is fixedly connected to the outer wall of the overall bracket 1. A sliding rod 406 is slidably connected to the inner wall of the first seedling clamping plate 401. When the first seedling clamping plate 401 rotates, it synchronously drives the sliding rod 406 to move. When the first seedling clamping plate 401 drives the sliding rod 406 to move into contact with the arc-shaped block 404, at this time, the sliding rod 406 will be squeezed by the arc-shaped block 404 and contract, driving the subsequent components to perform the clamping operation on the Codonopsis pilosula seedlings.

[0036] The cleaning and extrusion assembly 4 further includes a fixed block 407 fixedly connected to the outer wall of the sliding rod 406. The outer wall of the fixed block 407 is slidably connected to the inner wall of the first seedling clamping plate 401. A telescopic spring 408 is fixedly connected to the outer wall of the sliding rod 406. By using the feature that the first rotating rod 204 rotates continuously as described above, a first seedling clamping plate 401 is provided. When the first rotating rod 204 rotates, it synchronously drives the first seedling clamping plate 401 and the elastic sponge 402 to rotate. When the first seedling clamping plate 401 rotates, it drives the sliding rod 406 to move. When the sliding rod 406 contacts the arc-shaped block 404, the sliding rod 406 is pressed to move towards the elastic sponge 402 and drives the fixed block 407 to move synchronously. At this time, the Codonopsis pilosula seedlings moving downward along the conveyor belt 306 will fall between the fixed block 407 and the elastic sponge 402 and then be clamped by the fixed block 407 and the elastic sponge 402 moving outward. When the first seedling clamping plate 401 rotates downward, it is inserted into the soil. After the sliding rod 406 loses contact with the arc-shaped block 404, the sliding rod 406 drives the fixed block 407 to move under the action of the telescopic spring 408, and the Codonopsis pilosula seedlings lose the clamping force and thus fall into the soil to achieve the purpose of planting. When the first seedling clamping plate 401 continues to rotate, since the fixed block 407 contracts inward under the action of the telescopic spring 408, when it rotates to the fixed scraper 409, the outer surface of the fixed block 407 will contact the fixed scraper 409, and the soil on the fixed block 407 will be scraped off. This is to prevent the distance between the fixed block 407 and the elastic sponge 402 from decreasing after the soil adhered to the fixed block 407 caking, which may cause the Codonopsis pilosula seedlings to be unable to fall between the two, and thus unable to be clamped, affecting the planting of the Codonopsis pilosula seedlings. Or after the distance between the fixed block 407 and the elastic sponge 402 decreases, because the moving distance of the fixed block 407 remains unchanged, the clamping force on the Codonopsis pilosula seedlings becomes larger, causing damage to the Codonopsis pilosula seedlings during clamping and affecting the subsequent survival rate.

[0037] The cleaning and extrusion assembly 4 further includes a fixed scraper 409 fixedly connected to the outer wall of the connecting rod 405. A spring scraper 410 is slidably connected to the inner wall of the connecting rod 405. The outer wall of the spring scraper 410 is slidably connected to the outer wall of the elastic sponge 402. As described above, when the first rotating rod 204 rotates, it drives the elastic sponge 402 and the second seedling clamping plate 403 to rotate. When the elastic sponge 402 rotates continuously, it will continuously contact the spring scraper 410. Due to the action of the spring, the spring scraper 410 will closely adhere to and extrude the elastic sponge 402, causing the elastic sponge 402 to be scraped and extruded during continuous rotation, so that the residual sticky soil impurities on the elastic sponge 402 are scraped off. At the same time, due to the extrusion of the spring scraper 410, most of the water in the elastic sponge 402 can be extruded and drained, avoiding the situation that when there is a lot of water in the soil and the elastic sponge 402 has been working for a period of time, the elastic sponge 402 will absorb a lot of water. When there is a lot of water in the elastic sponge 402, it may affect the resilience of the elastic sponge 402, which will affect the clamping of the codonopsis pilosula seedlings. At the same time, when the elastic sponge 402 absorbs a lot of water, its weight will also increase, thereby increasing the burden on the motor 201.

[0038] The ditch digging and anti-overflow assembly 5 includes a conical plate 501 fixedly connected to the bottom of the overall bracket 1. A third rotating rod 502 is rotatably connected to the inner wall of the conical plate 501. The bottom of the third rotating rod 502 is fixedly connected to a pressure receiving plate 503. The outer wall of the pressure receiving plate 503 is rotatably connected to the inner wall of the conical plate 501. Due to the conical design of the front of the conical plate 501, when the traction device drives the transplanting device to move forward, the conical plate 501 will dig a ditch and open a groove in the soil to facilitate the subsequent planting of codonopsis pilosula seedlings. When opening the groove, the extruded soil will move from the middle of the conical plate 501 to both sides. When the soil moves to both sides, it will push the pressure receiving plate 503 to rotate.

[0039] The ditch-digging anti-overflow component 5 further includes a conveyor belt 504 rotatably connected to the outer wall of the third rotating rod 502. The outer wall of the conveyor belt 504 is slidably connected to the inner wall of the conical plate 501. The outer wall of the conveyor belt 504 is fixedly connected with a fixing plate 505, and the outer wall of the fixing plate 505 is slidably connected to the inner wall of the conical plate 501. Utilizing the feature that the transplanting device is pulled forward by a traction device, a conical plate 501 is provided. When the device advances, the conical plate 501 can dig a ditch and groove in the soil. While digging the ditch and groove, the soil will accumulate more and more, and move from the middle of the conical plate 501 to both sides. When the soil moves to both sides, it will push the pressure-receiving plate 503 to rotate. When the pressure-receiving plate 503 rotates, it drives the conveyor belt 504 and the fixing plate 505 to rotate through the third rotating rod 502. When the fixing plate 505 rotates, it can drive the soil gradually bulging in the middle of the conical plate 501 to both sides, preventing the soil gradually bulging in the middle of the conical plate 501 from falling behind the conical plate 501 during continuous advancement, so that the ditch and groove dug in the soil do not reach the specified depth, there is more soil in the ditch, and when clamping and inserting Codonopsis pilosula seedlings, the Codonopsis pilosula seedlings come into contact with the soil too much, causing the Codonopsis pilosula seedlings to bend excessively or even break during planting, thus affecting the growth and survival rate of the Codonopsis pilosula seedlings.

[0040] The ditch-digging anti-overflow component 5 further includes an auxiliary guide wheel 506 rotatably connected to the inner wall of the conical plate 501. The outer wall of the auxiliary guide wheel 506 is rotatably connected to the inner wall of the conveyor belt 504. The outer wall of the overall bracket 1 is fixedly connected with a fourth fixing bracket 507, and the outer wall of the fourth fixing bracket 507 is rotatably connected with a rolling wheel 508. The auxiliary guide wheel 506 makes the conveyor belt 504 rotate more smoothly, avoiding the situation of being blocked and stuck midway. When the overall equipment advances, the fourth fixing bracket 507 drives the rolling wheel 508 to rotate. When the rolling wheel 508 rotates, it brings the soil accumulated on both sides into the dug ditch for soil covering operation to ensure that the Codonopsis pilosula seedlings are covered with soil.

[0041] A specific application of this embodiment is as follows: Before using the device, first install the device behind the traction device and connect the power supply of the motor 201. When the motor 201 is powered on and running, it drives the pulley 202 to rotate. Then, through the transmission of the first belt 203, the first rotating rod 204 rotates synchronously. When the first rotating rod 204 rotates, the worm 205 drives the worm rod 206 to rotate together. Then, through the transmission of the second belt 207, the transmission guide wheel 305 is driven to rotate. When the transmission guide wheel 305 rotates, the second rotating rod 302 is driven to rotate through the second gear 304 and the first gear 303. After the bundled Codonopsis pilosula seedlings are placed in the feeding trough 301, they slide down along the inclined surface of the side wall of the feeding trough 301 to the second rotating rod 302. When the second rotating rod 302 rotates, it can drive the spring convex block 308 to be stuck between the Codonopsis pilosula, and then separate the two during the rotation. At the same time, when the spring convex block 308 directly contacts the Codonopsis pilosula seedlings, the spring convex block 308 will be compressed and contract inward to avoid squeezing the Codonopsis pilosula seedlings during rotation and causing damage to them. After the separated Codonopsis pilosula seedlings are pushed away from the feeding trough 301, they fall downward onto the conveyor belt 306. Through the blockage of the partition 307, the Codonopsis pilosula seedlings are stuck on the protruding teeth 309, preventing them from rolling directly downward and affecting the subsequent clamping and planting of the Codonopsis pilosula seedlings. At the same time, it also prevents two Codonopsis pilosula seedlings from falling simultaneously, resulting in the situation where neither of them is stuck by the protruding teeth 309. Through the operation of the above components, the bundled Codonopsis pilosula seedlings can be automatically separated into individual Codonopsis pilosula seedlings, facilitating the subsequent clamping and planting of the Codonopsis pilosula seedlings, improving the working efficiency during planting, and avoiding the inconvenience of manually separating the bundled Codonopsis pilosula seedlings and then placing them on the conveyor belt 306, which affects the planting efficiency.

[0042] Taking advantage of the characteristic that the first rotating rod 204 rotates continuously as described above, a first seedling clamping plate 401 is provided. When the first rotating rod 204 rotates, it synchronously drives the first seedling clamping plate 401 and the elastic sponge 402 to rotate. When the first seedling clamping plate 401 rotates, it drives the sliding rod 406 to move. When the sliding rod 406 moves to contact the arc-shaped block 404, the sliding rod 406 will be pressed to move towards the elastic sponge 402 and drive the fixed block 407 to move synchronously. At this time, the Codonopsis pilosula seedlings moving downward along the conveyor belt 306 will fall between the fixed block 407 and the elastic sponge 402, and then be clamped by the outward-moving fixed block 407 and elastic sponge 402. When the first seedling clamping plate 401 rotates downward, it is inserted into the soil. After the sliding rod 406 loses contact with the arc-shaped block 404, the sliding rod 406 drives the fixed block 407 to move under the action of the telescopic spring 408, and the Codonopsis pilosula seedlings lose the clamping force and thus fall into the soil to achieve the purpose of planting. When the first seedling clamping plate 401 continues to rotate, since the fixed block 407 contracts inward under the action of the telescopic spring 408, when it rotates to the fixed scraper 409, the outer surface of the fixed block 407 will contact the fixed scraper 409, and the soil on the fixed block 407 will be scraped and removed. This is to prevent the distance between the fixed block 407 and the elastic sponge 402 from decreasing after the soil adhered to the fixed block 407 caking, which may cause the Codonopsis pilosula seedlings to be unable to fall between the two, and thus unable to be clamped, affecting the planting of the Codonopsis pilosula seedlings. Or after the distance between the fixed block 407 and the elastic sponge 402 decreases, since the moving distance of the fixed block 407 remains unchanged, the clamping force on the Codonopsis pilosula seedlings becomes larger, causing damage to the Codonopsis pilosula seedlings during clamping and affecting the subsequent survival rate. When the elastic sponge 402 rotates continuously, it will continuously contact the spring scraper 410. Due to the action of the spring, the spring scraper 410 will closely adhere to and squeeze the elastic sponge 402, so that the elastic sponge 402 is scraped and squeezed by the spring scraper 410 during continuous rotation, and the residual sticky soil impurities on the elastic sponge 402 are scraped off. At the same time, due to the extrusion of the spring scraper 410, most of the water in the elastic sponge 402 can be squeezed out. This is to avoid that due to the water absorption characteristic of the sponge, when there is more water in the soil and after working for a period of time, the elastic sponge 402 will absorb more water. When there is more water in the elastic sponge 402, it may affect the resilience of the elastic sponge 402, thus affecting the clamping of the Codonopsis pilosula seedlings. At the same time, when the elastic sponge 402 absorbs more water, its weight will also increase, thereby increasing the burden on the motor 201.

[0043] Taking advantage of the feature that the transplanting device is pulled forward by a traction device, a conical plate 501 is provided. When the device moves forward, the conical plate 501 can dig trenches and grooves in the soil. While digging the trenches and grooves, the soil will accumulate more and more, and move from the middle of the conical plate 501 to both sides. When the soil moves to both sides, it will push the pressure-receiving plate 503 to rotate. When the pressure-receiving plate 503 rotates, the conveyor belt 504 and the fixing plate 505 are driven to rotate by the third rotating rod 502. When the fixing plate 505 rotates, the soil gradually bulging in the middle of the conical plate 501 can be driven to both sides of it, preventing the soil gradually bulging in the middle of the conical plate 501 from falling behind the conical plate 501 during continuous forward movement, resulting in the trenches and grooves dug in the soil not reaching the specified depth, having more soil in the trenches, and when clamping and inserting Codonopsis pilosula seedlings, the Codonopsis pilosula seedlings contacting the soil too much, causing the Codonopsis pilosula seedlings to bend excessively or even break during planting, thus affecting the growth and survival rate of the Codonopsis pilosula seedlings.
