Description

Technical Field

[0001] This invention relates to the field of sweet potato transplanter technology, specifically to a sweet potato transplanter seedling replenishment device and method. Background Technology

[0002] With the development of sweet potato transplanter technology in recent years, sweet potato transplanters can now perform functions such as ditching, seedling placement, and soil covering. However, problems such as missed planting and seedling damage still exist in actual operation, and manual intervention is still required for replanting. Missed planting is difficult to detect during the operation of the sweet potato transplanter, and manually identifying and replanting missed plantings is time-consuming and labor-intensive, limiting further improvements in sweet potato yield and planting efficiency. Therefore, it is necessary to propose a device that can monitor missed planting during the operation of the sweet potato transplanter and promptly replant seedlings. Summary of the Invention

[0003] The purpose of this invention is to provide a sweet potato transplanter seedling replenishment device and method. The seedling delivery device enables replenishment when missed seedlings are detected. First, multiple seedling placement plates are sequentially arranged on a tray via a clamp. A seedling retrieval clamp picks up the corresponding seedling from the placement plate for replenishment. Empty placement plates automatically fall after the telescopic plate retracts. After the telescopic plate resets, a screw motor drives a sliding block to move, pushing multiple placement plates to replenish the telescopic plate with new seedlings for the next retrieval. This achieves automated replenishment of missed sweet potato seedlings. The seedling retrieval plates are also automatically replenished, and empty placement plates automatically fall into a collection box for recycling.

[0004] To achieve the above objectives, the present invention provides a sweet potato transplanter seedling replenishment device, which includes a transplanter frame, a frame mounted on the transplanter frame, and a seedling replenishment clamp mounted on the frame. It also includes a seedling delivery device installed at the rear of the frame, the seedling delivery device comprising:

[0005] A lead screw module includes a lead screw motor mounted on the frame and a push slider that can be driven by the lead screw motor, wherein a push plate is connected to the push slider;

[0006] A carrier plate frame is mounted above the lead screw module;

[0007] A tray can be placed on a tray frame; slots are formed on both sides of the tray; multiple seedling trays are moved in along the slots and arranged sequentially on the tray; both the tray frame and the tray have openings.

[0008] A collection frame is located below the end of the tray furthest from the lead screw motor;

[0009] A telescopic plate is located below the carrier frame. The telescopic plate can be driven by an electric push rod to move between a first position and a second position. When the push slider is driven by the lead screw motor, the push plate pushes multiple seedling placement plates arranged on the tray along the opening, and the outermost seedling placement plate is on the telescopic plate extended to the first position. At this time, the outermost seedling placement plate can be picked up by the replanting seedling clip. After the telescopic plate is retracted from the first position to the second position, the outermost empty seedling placement plate loses its support and falls into the collection frame.

[0010] Preferably, the frame is fastened to the rear of the vehicle frame by U-bolts.

[0011] As a preferred option, it also includes:

[0012] A slide rail is fixed on the frame, and a movable slider is provided on the slide rail;

[0013] A support frame is provided on the movable slider; the replanting and seedling-taking clip is provided on the side of the support frame, and the support frame is also provided with a drive motor, which is used to drive the replanting and seedling-taking clip to clamp and plant seedlings; the movable slider can move along the slide rail to adjust the position of the replanting and seedling-taking clip.

[0014] Preferably, the lead screw module further includes:

[0015] A lead screw support is provided, wherein the output end of the lead screw motor is connected to the lead screw through the lead screw support, and the push slider is disposed on the lead screw; the carrier plate frame is fixed on the lead screw support.

[0016] Preferably, the electric push rod is installed below the carrier frame, and a slot is provided below the carrier frame. The two sides of the telescopic plate are located in the slot so that the telescopic plate can move along a preset path between a first position and a second position.

[0017] Preferably, the telescopic rod is a U-shaped mechanism that is recessed toward the lead screw module.

[0018] As a preferred option, it also includes:

[0019] A placement rack is fixed to the carrier plate rack, and the collection frame is placed inside the placement rack.

[0020] As a preferred option, it also includes:

[0021] A high-speed camera is mounted on the transplanter frame in front of the seedling grabber and is used to collect image information on whether the seedling grabber of the transplanter has successfully grabbed the sweet potato seedling.

[0022] The main control box is located on the transplanter frame. The main control box is configured to determine whether the transplanter's seedling picker has missed planting based on the image information; if it is determined that there is a missed planting, a replanting command is issued.

[0023] The present invention also provides a method for replanting seedlings using a sweet potato transplanter replanting device, which is based on the aforementioned sweet potato transplanter replanting device, the replanting method comprising:

[0024] Step S1: Arrange multiple seedling trays carrying sweet potato seedlings on the tray in sequence along the slots of the tray;

[0025] Step S2: The transplanter frame is towed and started. During the transplanting process, the transplanter's seedling-grabbing clamp is monitored in real time to see if the seedling has been successfully picked up.

[0026] Step S3: If no seedling removal failure is detected, the transplanter continues to move forward and the seedling replenishment device does not operate; if seedling removal failure is detected, a replanting command is issued.

[0027] Step S4: In response to the replanting command, the replanting seedling grabber picks up the sweet potato seedlings on the outermost seedling board for replanting; the telescopic plate retracts from the first position to the second position, the outermost empty seedling board falls into the collection frame, and then the telescopic plate extends and resets to the first position, and the push slider pushes multiple seedling boards to place the outermost new seedling board carrying sweet potato seedlings on the telescopic plate in the first position.

[0028] Preferably, the replanting seedling grabber can move on the frame, and the transplanter seedling grabbers at at least two positions can be monitored in real time during the transplanting process to see if the seedlings have been successfully grabbed.

[0029] The replanting method also includes:

[0030] If the transplanter fails to pick up a seedling at one of the locations, the replanting seedling picker can be moved along the frame to that location and pick up the sweet potato seedling on the corresponding seedling board for replanting.

[0031] If all the sweet potato seedlings on the tray have been replanted, a buzzer signal will be issued in the main control box, and the tray will be replaced with one fully loaded with sweet potato seedlings before continuing operation.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] This invention provides a sweet potato transplanter seedling replenishment device and method that can be used in sweet potato transplanters with double rows or single rows per ridge. It can quickly detect the planting status of sweet potato seedlings during field operation and, in conjunction with the seedling replenishment device at the rear of the transplanter, perform rapid and accurate seedling delivery and replenishment. This solves the problem of manual detection and timely replenishment of missed seedlings during machine operation, thus helping to increase sweet potato yield. The seedling replenishment device and method used in this invention have a high degree of automation. Simply place the seedling-fixed trays along the slots on the pallet, and then place the trays on the carrier frame. Upon receiving a replenishment command, the seedling replenishment device will automatically complete the replenishment operation. After all the sweet potato seedlings on the pallets have been replenished, simply change the clothes to fill the trays with seedlings, thus solving the problem of time-consuming and labor-intensive manual replenishment of sweet potato seedlings.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0042] Example 1

[0043] from Figure 1-5 This embodiment provides a sweet potato transplanter seedling replenishment device, which includes a frame 2 mounted on the transplanter frame 1 and a seedling grabber 8 mounted on the frame 2. It also includes a seedling delivery device installed at the rear of the frame 2. The seedling delivery device includes a screw module, a carrier plate frame 10, a tray 5, a collection frame 12, and a telescopic plate 18. The screw module includes a screw motor 4 mounted on the frame 2 and a pusher slider 17 driven by the screw motor 4. A pusher plate is connected to the pusher slider 17. The carrier plate frame... 10 is positioned above the lead screw module; the tray 5 can be placed on the tray frame 10; slots 21 are formed on both sides of the tray 5; multiple seedling trays 9 are moved in along the slots 21 and arranged sequentially on the tray 5, and openings are formed on both the tray frame 10 and the tray 5; the collection frame 12 is positioned below the end of the tray 5 away from the lead screw motor 4; the telescopic plate 18 is positioned below the tray frame 10, and the telescopic plate 18 can be driven by the electric push rod 11 to move between a first position and a second position.

[0044] When the push slider 17 is driven to move by the lead screw motor 4, the push plate pushes the multiple seedling plates 9 arranged on the support plate 5 along the opening, and the outermost seedling plate 9 is placed on the telescopic plate 18 in the first position. The telescopic plate 18 extends out, and at this time, the outermost seedling plate 9 can be picked up by the replanting seedling clip 8. After the telescopic plate 18 moves from the first position to the second position and retracts, the outermost empty seedling plate 9 loses support and falls into the collection frame 12. In practical use, this embodiment can replant seedlings for missed planting situations using the seedling replanting clip 8. After being grabbed by the seedling replanting clip 8, the empty seedling placement plate 9 can be automatically lowered and retrieved by controlling the telescopic plate 18 to retract to the second position. After the telescopic plate 18 extends and resets to the first position, under the drive of the lead screw motor 4, the push slider 17 drives multiple seedling placement plates 9 to move through the push plate to push the new seedling placement plate 9 carrying sweet potato seedlings onto the telescopic plate 18 which is in the first position, so that the seedling replanting clip 8 can pick it up again, thereby realizing the automated replanting operation for missed planting situations.

[0045] Specifically, the seedling replenishment device in this embodiment includes a seedling leakage detection device, a planting device, a seedling delivery device, and a control system, all fixedly mounted on the frame 1. The frame 1 provides necessary support for the seedling leakage detection device, planting device, seedling delivery device, and control system. The machine frame 2 is fastened to the rear of the frame 1 by U-bolts. The seedling leakage detection device includes two high-speed cameras 14 and a main control box 15. Two high-speed cameras 14 are fixed to the front end of the frame, with their camera lenses aligned with the seedling clamps 16 of the transplanter. These cameras are used to detect the image information of the sweet potato seedlings being picked up by the left and right seedling clamps 16 of the transplanter, and transmit the captured image information to the CPU located in the main control box 15 on the right side of the frame to determine whether the seedling clamps 16 have successfully planted the sweet potato seedlings.

[0046] The planting device includes a slide rail 3 on the frame 2, a movable slider 6 on the slide rail, a support frame on the movable slider 6, a drive motor 7 on the support frame, and a replanting and seedling-taking clamp 8. The movable slider 6 slides in the slide rail 3 under the command of the PLC in the main control box 15. A support frame 19 is fixed on the movable slider 6, which provides support for the drive motor 7 and the replanting and seedling-taking clamp 8. The movable slider 6 can move along the slide rail 3 to adjust the position of the replanting and seedling-taking clamp 8. In a specific embodiment, the replanting and seedling-taking clamp 8 is a crank-rocker mechanism. The PLC sends different pulse signals to the drive motor 7 to make the drive motor 7 rotate different numbers of revolutions to control the clamping and planting of seedlings by the replanting and seedling-taking clamp 8.

[0047] The seedling feeding device includes a lead screw motor 4, a lead screw support 22, a carrier plate frame 10, a support plate 5, a pusher slider 17, an electric push rod 11, and a telescopic plate 18, all fixed above the tail of the frame 1. The output end of the lead screw motor 4 is connected to the lead screw through the lead screw support 22, and the pusher slider 17 is mounted on the lead screw. The carrier plate frame 10 is fixed on the lead screw support 22. Below the carrier frame 10 is a collection frame 12 for collecting empty seedling trays 9. The tray 5 has a latch 21 for fixing the seedling tray 9 so that when the replanting seedling tweezers 8 pick up sweet potato seedlings from the seedling tray 9, the seedling tray 9 will not move. The tray 5 has an opening in the middle for pushing the slider 17 to move. An electric push rod 11 and a slot 23 are fixed below the carrier frame 10. The telescopic plate 18 is controlled by the electric push rod 11 to extend and retract along a preset path in the slot 23. The telescopic plate extends in the first position to support the seedling tray and retracts in the second position to move the empty seedling tray down.

[0048] A placement frame 13 is fixed below the carrier frame 10. This placement frame provides support for the collection frame 12, which is used to collect the seedling placement plate 9 that has been clamped with sweet potato seedlings. During operation, the seedling placement plate 9 with the fixed sweet potato seedlings is arranged along the slot 21 of the tray 5 from the position of the baffle 20 on the tray 5 to the end. After receiving the replanting instruction, the drive motor 7 drives the replanting seedling clamp 8 to move the crank rocker to clamp the sweet potato seedling from the seedling placement plate 9. The seedling placement plate 9 at the end is in an unloaded state. The electric push rod 11 at the bottom of the carrier frame 10 completes a retraction and extension action of the telescopic plate 18 through the instruction of the PLC in the main control box 15. When the telescopic plate 18 retracts, the unloaded seedling placement plate 9 falls into the collection frame 12 under the action of gravity. Then the telescopic plate 18 extends, and the lead screw motor 4 drives the push slider 17 to move forward and push the seedling placement plate forward. The seedling placement plate 9 with fixed sweet potato seedlings reappears above the telescopic plate 18, which is convenient for replanting when the next replanting instruction is issued.

[0049] In this embodiment, the telescopic plate 18 is a U-shaped mechanism. This structure is designed to prevent the lead screw support 22 from blocking the telescopic plate 18 when the electric push rod 11 drives it to retract, thus preventing the telescopic plate 18 from retracting. The collection frame 12 collects the seedling placement plate 9, allowing it to be recycled and reused for placing sweet potato seedlings again.

[0050] The control system consists of a CPU processor and a PLC controller in the main control box 15. The CPU processor is connected to the seedling leakage detection device and the PLC controller via a connecting cable. The CPU processor identifies and processes the seedling clamping information captured by the high-speed camera 14, and transmits the seedling leakage information to the PLC controller. The PLC controller is connected to the planting device and the seedling delivery device via a connecting cable. After receiving the seedling leakage information transmitted by the CPU processor, the PLC controller controls the slider 6, the drive motor 7, and the lead screw motor 4 to perform different actions to realize the replanting operation of the transplanter.

[0051] The working steps of the sweet potato transplanter seedling replenishment device in this embodiment are as follows: First, multiple seedling trays 9 carrying sweet potato seedlings are arranged sequentially on the tray 5 along the slot 21; the transplanter frame 1 is started by traction, and the transplanter seedling clamp 16 is monitored in real time during the transplanting process to see if the seedling is successfully picked up; if no seedling failure is detected, the transplanter continues to move forward, and the seedling replenishment device does not operate; if seedling failure is detected, a replanting command is issued; in response to the replanting command, the replanting seedling clamp 8 picks up the sweet potato seedling on the outermost seedling tray 9 for replanting; the telescopic plate 18 moves from the first position to the second position and retracts, and the outermost empty seedling tray 9 falls into the collection frame 12. Then the telescopic plate 18 extends and resets to the first position, and the push slider 17 pushes multiple seedling trays 9 to place the outermost new seedling tray 9 carrying sweet potato seedlings on the telescopic plate 18 in the first position.

[0052] Furthermore, the replanting seedling grabber 8 in this embodiment can move on the frame 2. During the transplanting process, it monitors in real time whether the seedling grabbers 16 at at least two positions, such as the left and right sides, have successfully grabbed seedlings. If the seedling grabber 16 at one of the positions fails to grab a seedling, the replanting seedling grabber 8 can be moved along the frame 2 to that position and grab the sweet potato seedling on the corresponding seedling plate 9 for replanting. In addition, if all the sweet potato seedlings on the seedling plates 9 on the tray 5 have been replanted, a buzzer signal is issued in the main control box 15, and the tray 5 is replaced with one full of sweet potato seedlings before continuing to work.

[0053] Example 2

[0054] This embodiment provides a method for replanting seedlings using a sweet potato transplanter replanting device as described in Embodiment 1, which includes:

[0055] S1: Place the seedling plate 9 along the slot 21 of the tray plate onto the tray plate 5, place the sweet potato seedlings on the seedling plate 9, and then place the tray plate 5 on the carrier frame 10.

[0056] S2: The sweet potato transplanter is started by tractor pulling. Two high-speed cameras 14 located in front of the transplanter frame 1 take pictures to obtain the seedling picking information of the transplanter's seedling picking clip 16 and transmit it to the CPU processor of the main control box 15. The CPU processor uses a trained discrimination model to determine whether the transplanter's seedling picking clip 16 has missed planting and transmits the information on whether it has missed planting to the PLC of the main control box 15.

[0057] S3: If the CPU processor determines that there are no missing seedlings, it will not send a replanting command to the PLC controller, the machine will continue to move forward, and the seedling replanting device will not take any action.

[0058] S4: If the CPU processor identifies a missed planting, it sends a replanting command to the PLC controller. If the image from the right high-speed camera 14 identifies a missed planting, the PLC controller sends a pulse signal to the drive motor 7. The drive motor 7 drives the replanting and seedling picking clamp 8 to move the crank arm, making a planting action, completing the replanting, and waiting for the next replanting command to be issued.

[0059] S5: During the process of replanting sweet potato seedlings by the seedling grabber 8, the seedling placement plate 9 after the seedlings are grabbed is empty. At this time, the PLC controller sends a command to the electric push rod 11. The electric push rod 11 pulls back to retract the telescopic plate. The empty seedling placement plate 9 falls into the collection frame 12 under the action of gravity. Then the electric push rod 11 pushes forward to extend the telescopic plate 18 again. After the telescopic plate 18 is reset, the PLC controller sends a pulse signal to the lead screw motor 4. The lead screw motor 4 drives the push slider 17 to move forward and push the new seedling placement plate 9 carrying sweet potato seedlings to the predetermined position so that the seedling grabber 8 can complete the seedling grabbing and planting operation in time when the next replanting command is issued.

[0060] S6: If the image captured by the high-speed camera 14 on the left is identified as a missed planting, the PLC controller sends a pulse signal to the drive motor 7. The drive motor 7 drives the replanting and seedling picking clamp 8 to complete the action of picking up the sweet potato seedling. At this time, the slider 6 moves to the left along the slide rail 3. After moving to the corresponding position, the PLC controller sends a pulse signal to the drive motor 7 again. The drive motor 7 drives the replanting and seedling picking clamp 8 to perform a crank rocker motion, so that the replanting and seedling picking clamp 8, which has already picked up the sweet potato seedling, completes the remaining planting action. After completing the replanting, the replanting and seedling picking clamp 8 resets, the slider resets to the right side along the slide rail, and the seedling delivery device repeats the previous operation to complete the seedling delivery, waiting for the next seedling replanting instruction to be issued.

[0061] S7: If the sweet potato seedlings on tray 5 have been replanted, a buzzer signal will be emitted in the main control box 15, and the staff can continue to work by simply replacing the tray 5 with one full of sweet potato seedlings.

[0062] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
