Description

Technical Field

[0001] This invention relates to the field of transplanting equipment technology, specifically to an integrated field transplanting and weeding device for spring rapeseed seedling tray cultivation. Background Technology

[0002] Spring rapeseed is a major oilseed crop in high-altitude and high-latitude regions of northern my country (such as Inner Mongolia, Qinghai, and Gansu). The use of tray seedling transplanting technology can effectively extend the growth period of spring rapeseed, avoid early spring low-temperature freezing damage and later frost, and at the same time improve land utilization and rapeseed yield. Currently, the field transplanting of spring rapeseed is usually divided into several independent processes. First, the seedbed is prepared by using a rotary tiller or weeder to remove weeds from the field. Second, the seedlings are planted in the plug trays by manual labor or semi-automatic transplanters. Finally, a separate irrigation operation (watering to settle the roots) is required. This step-by-step operation requires multiple visits to the field to complete weeding, transplanting, and irrigation, which is time-consuming, labor-intensive, and has low production efficiency. Summary of the Invention

[0003] In view of the above-mentioned shortcomings in the existing technology, the purpose of this invention is to provide an integrated field planting and weeding device that can accelerate production efficiency, has a low failure rate, and is easy to maintain.

[0004] The technical solution adopted by the present invention to achieve the above objectives is: an integrated field transplanting and weeding device for spring rapeseed seedling tray cultivation, including a tractor and an operating device connected to the tractor. The operating device includes a walking frame, a weeding mechanism, a transplanting mechanism, an irrigation mechanism, and a seedling supply mechanism. The weeding mechanism is provided on the front of the walking frame and is used to perform weeding operations on the land. The transplanting mechanism is located after the weeding mechanism on the walking frame. The seedling supply mechanism is also located on the walking frame. The seedling supply mechanism can supply spring rapeseed seedlings to the transplanting mechanism. The transplanting mechanism can transplant the spring rapeseed seedlings onto the land. The irrigation mechanism is located on the walking frame in conjunction with the transplanting mechanism. The irrigation mechanism can irrigate the transplanted spring rapeseed seedlings.

The lifting frame is slidably connected to the walking frame, and the lifting control device is provided on the walking frame. The lifting control device cooperates with the lifting frame to control the lifting and lowering of the lifting frame. The lifting frame is rotatably connected to the cutter wheel, and the lifting frame is provided with an inclined conveying component located at the rear of the cutter wheel. The lifting frame is provided with a collection frame corresponding to the top of the conveying component. The first driving device is poweredly connected to the cutter wheel and the conveying component. The conveying component includes a lower conveying roller, a conveyor belt, and an upper conveying roller. The lower conveying roller is rotatably connected to the lifting frame near the cutter wheel, and the upper conveying roller is rotatably connected to the lifting frame corresponding to the lower conveying roller. The conveyor belt is provided between the upper conveying roller and the lower conveying roller, and the upper conveying roller is positioned higher than the lower conveying roller. The first driving device is poweredly connected to the upper conveying roller, and the upper conveying roller is connected to the cutter wheel via a chain drive. A sliding mounting frame is fixedly connected to the upper conveying roller on the lifting frame, and the collection frame is slidably connected to the sliding mounting frame.

[0006] In one embodiment, the transplantation mechanism has the following structure: The transplantation mechanism includes a reciprocating motion module, a duckbill transplantation component, and a soil covering wheel assembly. The reciprocating motion module is mounted on the walking frame and includes a traction table capable of reciprocating motion. The walking frame is equipped with the duckbill transplanting component corresponding to the traction platform. The duckbill transplanting component includes a duckbill tube that can hold rapeseed seedlings. Under the action of the traction platform, after the duckbill tube descends and inserts into the ground, the duckbill tube opens. When the duckbill tube rises a certain distance, the duckbill tube is open. When it continues to rise, the duckbill tube closes. The soil-covering wheel set is provided on the walking frame corresponding to the duckbill tube.

[0007] Furthermore, the specific structure of the duckbill transplant component is as follows: the duckbill transplant component further includes a guide frame, a traction frame, and a guide component. The guide frame is fixedly connected to the walking frame. The guide frame is provided with a guide groove. The guide groove includes a first closed guide area and a bottom area located at the bottom of the first closed guide area. The first closed guide area is connected to the bottom area. A guide slope is provided between the top of the bottom area and the first closed guide area. The guide frame is provided with a partition frame corresponding to the bottom area. The partition frame divides the bottom area into a second closed guide area and an open and close guide area. The second closed guide area corresponds to the first closed guide area. The bottom of the partition frame is provided with an open and close socket, and the top of the partition frame is provided with a closed socket. A valve plate is rotatably connected to the top of the partition frame. The rotating part of the valve plate is fitted with a torsion spring. Under the action of the torsion spring, the valve plate closes the closed socket. The traction platform is fixedly connected to the traction frame via a connecting frame, the traction frame is slidably connected to the guide frame, and a base plate is fixedly connected to the bottom of the traction frame; The duckbill tube is located in the middle of the traction frame. The duckbill tube includes two sets of symmetrically arranged duckbill plates. Each set of duckbill plates is matched with a set of base plates. Each set of duckbill plates is fixedly connected to a guide post. The guide post is slidably connected to the corresponding base plate. Each set of guide posts is fixedly connected to a pressure plate. Each set of guide posts is fitted with a spring. One end of the spring is fixedly connected to the base plate, and the other end is fixedly connected to the pressure plate. Each set of guide posts is fixedly connected to a push plate at its end, the push plate is fixedly connected to the guide member, the top of the guide member is fixedly connected to a guide shaft, and the guide shaft is located in the guide groove. With the above structure, when the guide shaft descends along the first closed guide area and the second closed guide area, the two sets of duckbill plates close. When the guide shaft corresponds to the opening and closing socket, the two sets of duckbill plates open under the action of the spring, and the guide shaft corresponds to the opening and closing guide area. When the guide shaft rises along the opening and closing guide area, the two sets of duckbill plates open and close. When the guide shaft moves along the guide slope towards the first closed guide area, the guide shaft can push the valve plate to rotate and open. When the guide shaft rises and is located in the first closed guide area, the two sets of duckbill plates close.

[0008] In one embodiment, the seedling supply mechanism has the following structure: The seedling supply mechanism includes a rotating seedling supply tray, seedling cups, seedling guide tubes, and a first driving component. The seedling guide tubes are fixedly connected to the walking frame corresponding to the duckbill tubes. The rotating seedling supply trays are rotatably connected to the walking frame. Multiple sets of seedling cups are fixedly connected to the rotating seedling supply trays in a circular array. The bottom of the seedling cup is provided with a seedling inlet, and the bottom of the seedling cup is rotatably connected to a cup seat. A closed plate is fixedly connected to the bottom of the rotating seedling supply tray on the walking frame. The closed plate is provided with a seedling opening corresponding to the seedling guide tube. When a group of seedling cups corresponds to the seedling opening, the cup seat opens. The cup seats of the remaining seedling cups close the seedling inlet under the contact of the closed plate. The first drive component is provided on the walking frame and is poweredly connected to the rotating seedling tray. The first drive component cooperates with the traction platform so that when the traction platform rises, the traction platform can transmit power to the first drive component, and the first drive component can drive the rotating seedling tray to rotate a predetermined angle.

[0009] Furthermore, the first driving component adopts the following structure: The first driving component includes a worm, a worm wheel, a ratchet, a gear, and a rack. A transmission shaft is rotatably connected to the walking frame. The transmission shaft is poweredly connected to the rotating shaft of the rotating seedling tray.

An input shaft is fixedly connected to the end of the worm. The ratchet is provided on the input shaft. The gear is fixedly connected to the input shaft on the power input side of the ratchet. The rack is fixedly connected to the traction platform, and the rack meshes with the gear. Under the action of the ratchet, when the traction platform descends, the worm does not rotate, and when the traction platform rises, the worm rotates. Furthermore, a seat is fixedly connected to the walking frame corresponding to the rotating seedling tray, and seedling tray frames are fixedly connected to both sides of the seat on the walking frame.

[0010] In one embodiment, the irrigation mechanism has the following specific structure: The irrigation mechanism includes a water tank, an irrigation head, and a water supply control component. The water tank is fixedly connected to the walking frame, and the irrigation head is fixedly connected to the walking frame corresponding to the duckbill tube. The water tank, the water supply control component, and the irrigation head are connected by pipelines. The water supply control component is used to control the flow of water in the water tank. The water supply control unit is poweredly connected to the traction platform through a second drive component. When the traction platform rises, the water in the water tank flows out from the irrigation head. When the traction platform descends, the water in the water tank does not flow out from the irrigation head.

[0011] Furthermore, the structure of the water supply control component is as follows: the water supply control component includes a pump cylinder, a sealing piston, a first check valve, and a second check valve. The pump cylinder is fixedly connected to the walking frame. The sealing piston is provided inside the pump cylinder. A piston rod is fixedly connected to the sealing piston. The pump cylinder is provided with an inlet pipe and an outlet pipe. The first check valve is fixedly connected to the inlet pipe, and the second check valve is fixedly connected to the outlet pipe. The inlet pipe is connected to the water tank through an inlet pipe, and the outlet pipe is connected to the irrigation head through an outlet pipe. The piston rod is poweredly connected to the second drive component. Furthermore, the structure of the second driving component is as follows: the second driving component includes a lever arm, a fulcrum frame, and a driving arm. The fulcrum frame is fixedly connected to the walking frame, and the lever arm is rotatably connected to the fulcrum frame. The lever arm has a first sliding groove on one side of the fulcrum frame and a second sliding groove on the other side of the fulcrum frame. A first pressure shaft is fixedly connected to the top end of the piston rod. The first pressure shaft cooperates with the first sliding groove, allowing the first pressure shaft to rotate within the first sliding groove and slide linearly along the first sliding groove. The driving arm is fixedly connected to the traction platform, and a second pressure shaft is fixedly connected to the end of the driving arm. The second pressure shaft cooperates with the second sliding groove, allowing the second pressure shaft to rotate within the second sliding groove and slide linearly along the second sliding groove. When the above structure is adopted, under the action of the lever arm, when the traction platform descends, the piston rod drives the sealing piston to rise, and the water in the water tank enters the pump cylinder. When the traction platform rises, the piston rod drives the sealing piston to descend, and the water in the pump cylinder flows out through the pouring head.

[0012] In one embodiment, the reciprocating motion module is implemented using the following structure: The reciprocating motion module further includes a second drive device, a drive wheel, and a traction arm. A sliding frame is fixedly connected to the walking frame, and the traction platform is slidably connected to the sliding frame. A motion shaft is fixedly connected to the traction platform. The drive wheel is rotatably connected to the walking frame, and an eccentric shaft is fixedly connected to the drive wheel. The traction arm is rotatably connected to the eccentric shaft, and the other end of the traction arm is rotatably connected to the motion shaft. The second drive device is fixedly connected to the walking frame, and the second drive device is poweredly connected to the drive wheel.

[0013] The beneficial effects of this invention are: 1. The equipment integrates the four originally separate operation links of weeding, seedling supply, transplanting and watering into a single tractor-mounted agricultural implement. The transplanting of spring rapeseed no longer requires rotary tillage and weeding, followed by manual or semi-mechanical seedling planting and separate irrigation. The entire process can be completed in one trip to the field, which greatly reduces the number of operations and manual assistance time, and speeds up production efficiency. 2. The weeding mechanism is located at the front of the walking frame, ensuring that the rapeseed seedlings are planted in a clean seedbed free from weed competition. The blades are responsible for chopping the topsoil and weeds, while the weeds can then enter the inclined conveyor belt. At this time, the soil falls through the mesh of the conveyor belt, while the weeds are finally transported to the collection box. This allows for simultaneous collection of weeds, preventing them from remaining on the land and reviving, resulting in excellent weeding effect. At the same time, the lifting control device can raise the entire weeding mechanism according to the soil quality, humidity, or when encountering obstacles such as stones, protecting the blades and conveying components, and also facilitating road transportation. 3. Through the cooperation of the guide groove (first closed guide area, second closed guide area, opening and closing guide area, guide slope) with the guide shaft and spring, the entire action sequence of the duckbill tube's closing, insertion, opening, pulling out, and re-closing is precisely controlled. This purely mechanical forced control is more reliable than timing that relies on pneumatic or hydraulic systems, and is especially suitable for harsh environments with dust and vibration in the field. In addition, after the duckbill tube opens at the lowest point, it rises a certain distance (while still remaining open) to allow the seedling to completely detach from the duckbill tube and fall into the planting hole, and then continues to rise and close. This avoids the upward dragging or pinching of the seedling leaves when the duckbill tube is pulled out, thus improving the survival rate and planting uprightness. 4. Utilizing the upward movement of the traction platform, the rotation of the seedling tray is driven by a rack, gear, ratchet, worm, and worm wheel to rotate the seedling tray to one seedling position. No additional sensors or solenoid valves are required. The timing of "automatically sending the next seedling after planting" is achieved entirely by mechanical logic, resulting in a low failure rate. 5. By using the traction platform to descend (during transplantation), the lever arm drives the sealing piston to rise, thereby pumping a metered amount of water from the water tank into the pump cylinder. When the traction platform rises (after transplantation), the lever arm drives the piston to press the water onto the irrigation head, so that each seedling is watered once in a metered amount. Moreover, the irrigation time is just after the seedling is put into the soil and before the soil covering wheel group compacts it, so that the water can accurately penetrate into the root zone. In addition, this mechanical linkage structure is more durable and has a low equipment failure rate. Attached Figure Description

[0017] Please see Figures 1-3 An integrated field transplanting and weeding device for spring rapeseed seedling tray cultivation includes a tractor 101 and an operating device 102 connected to the tractor 101. The operating device 102 includes a walking frame 103, a weeding mechanism 201, a transplanting mechanism 301, an irrigation mechanism 501, and a seedling supply mechanism 401. The walking frame 103 is used to support and connect various functional mechanisms and to follow the tractor 101 in the field. The front of the walking frame 103 is equipped with a weeding mechanism 201, which is used to weed the land during the movement of the equipment, remove surface weeds and shallow roots, and create a clean seedbed for subsequent transplanting. A transplanting mechanism 301 is installed on the walking frame 103 after the weeding mechanism 201. A seedling supply mechanism 401 is also installed on the walking frame 103. The seedling supply mechanism 401 is used to supply spring rapeseed seedlings to the transplanting mechanism 301. The transplanting mechanism 301 is used to transplant the spring rapeseed seedlings to the land treated by the weeding mechanism 201. An irrigation mechanism 501 is also installed on the walking frame 103 in conjunction with the transplanting mechanism 301. The irrigation mechanism 501 is used to irrigate the transplanted spring rapeseed seedlings and provide water for root establishment. The specific implementation methods of each institution are described in detail below; First of all, please refer to Figure 2 , Figure 4 The weeding mechanism 201 includes a lifting frame 202, a lifting control device 203, a cutter wheel 204, a conveying component 205, a first drive device 206, and a collection frame 207. The lifting frame 202 is slidably connected to the traveling frame 103. Specifically, the front of the traveling frame 103 has a vertical sliding column or groove structure. The lifting frame 202 is mounted on the sliding column or groove via a sliding cylinder or roller, allowing the lifting frame 202 to move vertically up and down relative to the traveling frame 103. The 03 is equipped with a lifting control device 203, which works in conjunction with the lifting frame 202 to control the lifting height of the lifting frame 202. The lifting control device 203 can be a hydraulic cylinder, an electric push rod, or a screw and nut mechanism. One end of the device is fixed to the walking frame 103, and the other end is connected to the lifting frame 202. Through the extension and retraction of the lifting control device 203, the depth of the cutter wheel 204 into the soil can be adjusted. In addition, the weeding mechanism 201 can be lifted off the ground as a whole when transporting on the road or encountering obstacles. A cutter wheel 204 is rotatably connected to the lifting frame 202. The cutter wheel 204 is installed at the lower front part of the lifting frame 202, and its rotation axis is perpendicular to the direction of travel. Multiple cutting blades or toothed discs can be set on the outer circumference of the cutter wheel 204 for chopping weeds, cutting grass roots and loosening the topsoil. An inclined conveying component 205 is set on the lifting frame 202 at the rear of the cutter wheel 204. The front end (lower end) of the conveying component 205 is close to the lower rear of the cutter wheel 204 and is used to receive the weeds and some soil mixture thrown or shoveled by the cutter wheel 204. The rear end (higher end) of the conveying component 205 extends upward and backward at an incline. A collection frame 207 is set on the top of the lifting frame 202 corresponding to the top of the conveying component 205. The collection frame 207 is a box structure with an opening at the top and is used to hold the weeds conveyed by the conveying component 205. The first drive device 206 is poweredly connected to the cutter wheel 204 and the conveying component 205. The first drive device 206 can be a hydraulic motor or a motor with a gearbox, which drives the cutter wheel 204 to rotate and the conveying component 205 to operate simultaneously through chain, belt or gear 413 transmission. Furthermore, the conveying component 205 includes a lower conveying roller 208, a conveying mesh belt 209, and an upper conveying roller 210. The lower conveying roller 208 is rotatably connected to the lifting frame 202 near the cutter wheel 204.

The bottom sides of the collection frame 207 are provided with slide grooves or rollers that cooperate with the slide rails. The collection frame 207 can be pulled outward along the sliding mounting frame 211, so that it is convenient to remove and empty the collection frame 207 after it is filled with weeds, and then push it back into the working position.

[0018] Secondly, please refer to Figure 3 , Figures 5-13The transplantation mechanism 301 includes a reciprocating motion module 302, a duckbill transplantation component 304, and a soil covering wheel assembly 306. The reciprocating motion module 302 is provided on the walking frame 103. The reciprocating motion module 302 includes a traction table 303 that can realize reciprocating linear motion. Under the drive of the reciprocating motion module 302, the traction table 303 reciprocates in the vertical direction according to a set frequency and stroke. The duckbill transplantation component 304 is provided on the walking frame 103 corresponding to the traction table 303. The duckbill transplanting component 304 includes a duckbill tube 305 for placing spring rapeseed seedlings. Under the action of the traction platform 303, the duckbill tube 305 is lowered and inserted into the soil. After the duckbill tube 305 opens, the seedling is released. When the duckbill tube 305 rises a certain distance, the duckbill tube 305 remains open, allowing the seedling to completely detach from the duckbill tube 305. As the duckbill tube 305 continues to rise, it closes to prepare for the next seedling collection. In addition, on the walking frame 103, on both sides of the rear of the duckbill tube 305, there are soil covering wheel sets 306. The soil covering wheel sets 306 consist of two inclined disc wheels or rubber wheels. The two wheels are wider in the front and narrower in the back. After the duckbill tube 305 is pulled out, the soil on both sides of the planting hole is squeezed, so that the soil is backfilled to the roots of the seedling and compacted. Furthermore, the specific structure of the duckbill transplant component 304 is as follows: Please see Figure 8 , Figure 9 The duckbill transplant component 304 also includes a guide frame 307, a traction frame 314, and a guide member 321.

An opening and closing socket 310 is provided at the bottom of the partition 309. The opening and closing socket 310 is used to connect the second closed guide area 309a and the opening and closing guide area 309b. A closing socket 311 is provided at the top of the partition 309. A valve plate 312 is rotatably connected to the top of the partition 309. A torsion spring is sleeved on the rotation shaft of the valve plate 312. Under the elastic action of the torsion spring, the valve plate 312 maintains the tendency to close the closing socket 311. The traction table 303 is fixedly connected to the traction frame 314 via the connecting frame 313. The traction frame 314 is a rigid frame that moves together with the traction table 303. The traction frame 314 is slidably connected to the guide frame 307. Specifically, the guide frame 307 can be provided with a vertical sliding column.

The bottom of the traction frame 314 is fixedly connected to a base plate 315, which is horizontally arranged. The duckbill tube 305 is located in the middle of the traction frame 314. The duckbill tube 305 includes two sets of symmetrically arranged duckbill plates 316, namely the left duckbill plate 316 and the right duckbill plate 316. When the two are closed, they form a conical tube that is larger at the top and smaller at the bottom. Each set of duckbill plates 316 is correspondingly fitted with a set of base plates 315. Specifically, each set of duckbill plates 316 is fixedly connected with a guide post 317. The guide post 317 extends outward in the horizontal direction and is slidably connected to the corresponding base plate 315. The base plate 315 has a guide hole through which the guide post 317 passes. The hole can slide horizontally along the guide hole. Each set of guide posts 317 is fixedly connected to a pressure plate 318. Each set of guide posts 317 is fitted with a spring 319. One end of the spring 319 is fixedly connected to the outer side of the base plate 315, and the other end is fixedly connected to the inner side of the pressure plate 318. Each set of guide posts 317 is fixedly connected to a push plate 320. A guide member 321 is fixedly connected to the push plate 320. A guide shaft 322 is fixedly connected to the top of the guide member 321. The guide shaft 322 extends horizontally and is inserted into the guide groove 308 of the guide frame 307. The following action sequence is achieved using the above structure: Please see Figures 10-13 When the guide shaft 322 descends along the first closed guide area 308a and the second closed guide area 309a connected thereto, the guide shaft 322 is constrained by the side wall of the guide groove 308 and cannot move outward. Therefore, the two sets of duckbill plates 316 remain closed under the limiting action of the first closed guide area 308a, the spring 319 is in a stretched state, and the duckbill tube 305 is inserted into the soil in a closed state. When the guide shaft 322 descends along the second closed guide area 309a to the corresponding opening and closing socket 310, the guide shaft 322 loses its constraint and can move outward. At this time, under the elastic force of the spring 319, the two sets of guide posts 317 drive the duckbill plate 316 to open to both sides. At the same time, the guide shaft 322 automatically enters the opening and closing guide area 309b under the push of the spring 319. At this time, the duckbill tube 305 is in the open state, and the seedling falls into the planting hole. When the traction platform 303 begins to rise, driving the guide shaft 322 to move upward along the opening and closing guide area 309b, the two sets of duckbill plates 316 continue to remain open to ensure that the duckbill tube 305 will not clamp the seedling in the early stage of rising. When the guide shaft 322 rises to the top of the opening and closing guide area 309b, it closes through the cooperation of the guide slope 308c and the valve plate 312. Specifically, the guide shaft 322 continues to rise, contacts the guide slope 308c, and moves towards the first closing guide area 308a under the guidance of the guide slope 308c. During the movement, the guide shaft 322 pushes the valve plate 312 to rotate against the elastic force of the torsion spring, opening the closing socket 311. After the guide shaft 322 passes through the closing socket 311, it enters the first closing guide area 308a. At this time, the valve plate 312 resets under the action of the torsion spring and re-closes the closing socket 311. After the guide shaft 322 enters the first closing guide area 308a, it is forced to push inward by the constraint of the side wall of the first closing guide area 308a, thereby driving the two sets of duckbill plates 316 to overcome the thrust of the spring 319 and close in the middle. As the guide shaft 322 continues to rise, the duckbill tube 305 remains closed, completing one working cycle.

[0019] Furthermore, please refer to Figure 3 , Figures 14-17 The seedling supply mechanism 401 includes a rotating seedling supply tray 402, a seedling cup 403, a seedling guide tube 404, and a first driving component 405. A seedling guide tube 404 is fixedly connected to the walking frame 103 above the duckbill tube 305. The seedling guide tube 404 is a pipe with openings at the top and bottom, and its lower outlet is aligned with the top inlet of the duckbill tube 305. A rotating seedling supply tray 402 is rotatably connected to the walking frame 103. The rotating seedling supply tray 402 is a horizontally set disc, and its center is mounted on the walking frame 103 through a rotating shaft. It can rotate around the vertical axis. Multiple sets of seedling cups 403 are fixedly connected in a ring array on the rotating seedling supply tray 402. The seedling cup 403 is a cup-shaped container that is larger at the top and smaller at the bottom, and is used to hold a spring rapeseed seedling in a plug tray. The bottom of the seedling cup 403 is provided with a seedling inlet 406. A cup base 407 is rotatably connected to the bottom of the seedling cup 403. The cup base 407 can be a hinged door or a flip-up base plate hinged to the bottom of the seedling cup 403. A closed plate 408 is fixedly connected to the bottom of the rotating seedling supply tray 402 on the walking frame 103. The closed plate 408 is a fixed circular ring plate that fits against the lower surface of the rotating seedling supply tray 402. A seedling opening 409 is opened on the closed plate 408 at the position corresponding to the seedling guide tube 404. When a certain group of seedling cups 403 rotates to the position of the corresponding seedling opening 409, the cup seat 407 below the seedling cup 403 loses the support of the sealing plate 408 and flips downward under the action of gravity or the weight of the seedling, thereby opening the lower seedling opening 406, allowing the rapeseed seedlings in the seedling cup 403 to fall into the seedling guide tube 404 below. For the seedling cups 403 in other positions, the cup seat 407 is kept closed to the lower seedling opening 406 by the upper surface of the sealing plate 408, and the seedlings will not fall off. A first drive component 405 is provided on the walking frame 103 and is poweredly connected to the rotating seedling tray 402. The first drive component 405 is mechanically coordinated with the traction platform 303. Specifically, when the traction platform 303 moves upward, the traction platform 303 transmits power to the first drive component 405. The first drive component 405 drives the rotating seedling tray 402 to rotate by a predetermined angle so that the next seedling cup 403 containing a seedling is aligned with the seedling opening 409. When the traction platform 303 descends, the first drive component 405 does not output power and the rotating seedling tray 402 remains stationary. Furthermore, the first drive component 405 adopts the following structure: The first drive component 405 includes a worm gear 410, a worm wheel 411, a ratchet 412, a gear 413, and a rack 414. A transmission shaft 415 is rotatably connected to the walking frame 103. This transmission shaft 415 is poweredly connected to the central rotating shaft of the rotating seedling tray 402 via a coupling or a gear pair 413. A worm wheel 411 is fixedly connected to the transmission shaft 415. The worm gear 410 is rotatably connected to the walking frame 103, and the worm gear 410 is meshed with the worm wheel 411. It has a self-locking feature to prevent the rotating seedling tray 402 from rotating accidentally under external force. The end of the worm gear 410 is fixedly connected to the input shaft 416. The input shaft 416 is provided with a ratchet 412, which includes a ratchet and a pawl. Its function is to allow power transmission in only one direction. A gear 413 is fixedly connected to the input shaft 416 on the power input side of the ratchet 412. A rack 414 is fixedly connected to the traction table 303. The rack 414 is set vertically and meshes with the gear 413. Under the unidirectional transmission action of the ratchet 412, when the traction table 303 descends, the rack 414 drives the gear 413 to rotate in the opposite direction, but the ratchet 412 slips and the worm 410 does not rotate, which makes the rotating seedling tray 402 not rotate. When the traction platform 303 rises, the rack 414 drives the gear 413 to rotate in the forward direction, the ratchet 412 locks, and the power is transmitted to the rotating seedling tray 402 through the input shaft 416, worm 410, worm wheel 411, and transmission shaft 415, driving it to rotate at a predetermined angle. At this time, a set of seedling cups 403 corresponds to the seedling opening 409, and the rapeseed inside the seedling cups 403 falls into the seedling guide tube 404, and finally the seedling enters the closed duckbill tube 305. Furthermore, a seat 417 is fixedly connected to the walking frame 103 at the position corresponding to the rotating seedling tray 402. The seat 417 is used for the seedling placement personnel to sit. On both sides of the seat 417, a seedling tray rack 418 is fixedly connected to the walking frame 103. The seedling tray rack 418 is used to place seedling trays containing rapeseed seedlings, making it convenient for operators to take seedlings from the seedling trays and put them into the seedling cups 403.

[0020] Furthermore, please refer to Figure 3 , Figure 8 , Figure 19 The irrigation mechanism 501 includes a water tank 502, an irrigation head 503, and a water supply control component 504. The water tank 502 is fixedly connected to the traveling frame 103 and is used to store irrigation water. The irrigation head 503 is fixedly connected to the traveling frame 103 at a position corresponding to the duckbill tube 305. The outlet of the irrigation head 503 is aligned with the position of the duckbill tube 305 after planting, typically located in front of the soil covering wheel assembly 306. The water tank 502, water supply control component 504, and irrigation head 504 are also included. The three components are connected in sequence by pipelines. The water supply control component 504 is used to control the flow of water in the water tank 502. The water supply control component 504 is poweredly connected to the traction platform 303 through the second drive component 505. Specifically, when the traction platform 303 rises, the water in the water tank 502 flows out from the irrigation head 503 under water pressure or pumping action to irrigate the newly planted rapeseed seedlings. When the traction platform 303 falls, the water in the water tank 502 does not flow out from the irrigation head 503. Furthermore, the specific structure of the water supply control component 504 is as follows: Water supply control component 504 includes a pump cylinder 506, a sealing piston 507, a first check valve 508, and a second check valve 509. The pump cylinder 506 is fixedly connected to the traveling frame 103. The pump cylinder 506 is cylindrical. A sealing piston 507 is slidably and sealingly disposed inside the pump cylinder 506. A piston rod 510 is fixedly connected to the sealing piston 507, extending from one end of the pump cylinder 506. An inlet pipe 511 and an outlet pipe 512 are provided on the pump cylinder 506. A first check valve 509 is fixedly connected to the inlet pipe 511. Valve 508, the first one-way valve 508 only allows water to flow from the inlet pipe 511 into the pump cylinder 506, the outlet pipe 512 is fixedly connected to the second one-way valve 509, the second one-way valve 509 only allows water to flow from the pump cylinder 506 to the outlet pipe 512, the inlet pipe 511 is connected to the water tank 502 through the inlet pipe 513, the outlet pipe 512 is connected to the irrigation head 503 through the outlet pipe 514, the piston rod 510 is poweredly connected to the second drive component 505, the second drive component 505 drives the piston rod 510 to reciprocate; Furthermore, the specific structure of the second drive component 505 is as follows: The second drive component 505 includes a lever arm 515, a fulcrum frame 516, and a drive arm 517. The fulcrum frame 516 is fixedly connected to the walking frame 103, and the lever arm 515 is rotatably connected to the fulcrum frame 516. The lever arm 515 is a long strip rigid rod, and its middle part is rotatably connected to the top of the fulcrum frame 516 through a pin to form a fulcrum. A first sliding groove 518 is provided on one side of the fulcrum frame 516 on the lever arm 515. The first sliding groove 518 is an elongated oval through groove. A second sliding groove 519 is provided on the other side of the fulcrum frame 516 on the lever arm 515. The second sliding groove 519 is also an elongated oval through groove. The top end of the piston rod 510 is fixedly connected to a first pressure shaft 520. The first pressure shaft 520 is horizontally set and inserted into the first sliding groove 518. It cooperates with the first sliding groove 518 so that the first pressure shaft 520 can rotate in the first sliding groove 518 and slide along the straight direction of the first sliding groove 518. A drive arm 517 is fixedly connected to the traction table 303. The drive arm 517 moves together with the traction table 303. A second pressure shaft 521 is fixedly connected to the end of the drive arm 517. The second pressure shaft 521 is horizontally set and inserted into the second sliding groove 519. It cooperates with the second sliding groove 519 so that the second pressure shaft 521 can rotate in the second sliding groove 519 and slide along the straight direction of the second sliding groove 519. When the above structure is used, the motion relationship under the lever action of lever arm 515 is as follows: When the traction platform 303 descends, it drives the drive arm 517 and the second pressure shaft 521 to move downward. The second pressure shaft 521 presses down on the end of the second sliding groove 519 of the lever arm 515, causing the lever arm 515 to rotate around the fulcrum frame 516. The end of the first sliding groove 518 of the lever arm 515 is lifted upward. The first sliding groove 518 drives the piston rod 510 to move upward through the first pressure shaft 520, thereby causing the sealing piston 507 to move upward in the pump barrel 506. At this time, the volume of the inner cavity of the pump barrel 506 increases, generating negative pressure. The first one-way valve 508 opens, and the second one-way valve 509 closes. Water in the water tank 502 is sucked into the pump barrel 506 through the water inlet pipe 513 and the water inlet pipe 511. When the traction platform 303 rises, it drives the drive arm 517 and the second pressure shaft 521 to move upward. The second pressure shaft 521 lifts the end of the second sliding groove 519 of the lever arm 515, causing the lever arm 515 to rotate in the opposite direction around the fulcrum 516. The end of the first sliding groove 518 of the lever arm 515 is pressed downward. The first sliding groove 518 drives the piston rod 510 to move downward through the first pressure shaft 520, thereby causing the sealing piston 507 to move downward in the pump cylinder 506. At this time, the volume of the inner cavity of the pump cylinder 506 decreases and the pressure increases. The first one-way valve 508 closes and the second one-way valve 509 opens. The water in the pump cylinder 506 is forced out and flows out through the water outlet pipe 512, the water outlet pipe 514, and the irrigation head 503 to irrigate the roots of the newly planted rapeseed seedlings. Through the aforementioned mechanical linkage structure, the irrigation head 503 sprays water precisely once every time the traction platform 303 rises (i.e., every time a planting action is completed), thus achieving synchronous and precise irrigation.

[0021] Finally, please see Figure 7 , Figure 14 as well as Figure 18The reciprocating motion module 302 is used to drive the traction table 303 to perform reciprocating linear motion, and its specific structure is as follows: The reciprocating motion module 302 also includes a second drive device 323, a drive wheel 324, and a traction arm 325. A sliding frame 326 is fixedly connected to the traveling frame 103. A linear guide rail or guide column is provided on the sliding frame 326. The traction table 303 is slidably connected to the sliding frame 326 and can reciprocate along the length of the sliding frame 326. A motion shaft 327 is fixedly connected to the traction table 303. A drive wheel 324 is rotatably connected to the traveling frame 103. The drive wheel 324 can be driven to rotate by the second drive device 323. An eccentric shaft 328 is fixedly connected to the non-center position (i.e., the edge of the wheel) of the drive wheel 324. The eccentric shaft 328 moves in a circular motion with the drive wheel 324. One end of the traction arm 325 is rotatably connected to the shaft 328, and the other end of the traction arm 325 is rotatably connected to the motion shaft 327 of the traction table 303. A second drive device 323 is fixedly connected to the walking frame 103. The second drive device 323 can be a hydraulic motor or an electric motor. The second drive device 323 is poweredly connected to the drive wheel 324, driving the drive wheel 324 to rotate at a constant speed. When the drive wheel 324 rotates, the eccentric shaft 328 drives the traction arm 325 to swing back and forth, thereby driving the traction table 303 to move back and forth in a straight line on the sliding frame 326. By adjusting the speed of the drive wheel 324, the reciprocating frequency of the traction table 303 can be changed, thereby adjusting the planting spacing of the rapeseed seedlings.
