Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a seedling supply device and method for a potted seedling transplanter based on a decomposable seedling tray. Background Technology

[0002] Transplanting vegetables is one of the main cultivation methods. There are two methods: manual transplanting and machine transplanting. Manual transplanting is less efficient and more labor-intensive. Machine transplanting is relatively more efficient and less labor-intensive. Potted seedlings are seedlings cultivated in nutrient pots. The nutrient pots protect the seedling roots, facilitating transportation and transplanting. Potted seedlings are also more suitable for mechanized transplanting. Biodegradable seedling trays are made of organic, biodegradable materials. During transplanting, the tray material can be transplanted to the field along with the seedlings. After transplanting, it decomposes rapidly, integrating into the soil without affecting the later growth of the seedlings. Traditional potted seedling trays are made of plastic and cannot be transplanted to the field.

[0003] An existing patent discloses a vegetable seedling transplanting device, including a mounting frame. A first mounting plate and an elliptical push plate are slidably disposed within the mounting frame. The first mounting plate is located above the elliptical push plate, and multiple mounting slots are formed at the upper end of the first mounting plate. Each mounting slot contains a set of transplanting components for transplanting vegetable seedlings. A first cylinder and a second cylinder are fixedly connected to the lower inner wall of the mounting frame. The output end of the first cylinder is fixedly connected to the first mounting plate, and the output end of the second cylinder is fixedly connected to the elliptical push plate. This device achieves automatic drilling and transplanting of vegetable seedlings, reducing manual operation. It can move multiple seedlings simultaneously, effectively improving work efficiency. It is simple to operate and easy for users to use. While the aforementioned seedling transplanting device can transplant seedlings, it still requires manual handling of seedling picking and placement, which affects transplanting efficiency. Summary of the Invention

The transplanting mechanism moves the seedling box horizontally along the seedling gate beam. A rotary longitudinal cutting mechanism is set on the outside of the seedling gate to cut the seedling tray. A seedling receiving hopper is set below the seedling gate beam, and the seedling receiving hopper corresponds to the seedling gate. The seedling receiving hopper is installed on the frame and connected to the planting device of the transplanter. A tray position switch is set at the end of the guide rail, which controls the movement of the tray conveying mechanism. Seedling box position switches are set at both ends of the seedling gate beam. The seedling box position switches control the extreme positions of the left and right movement of the seedling box and the activation of the dial mechanism through the controller, so as to feed the seedling tray that has been horizontally cut into the seedling box.

[0006] Preferably, the conveying mechanism includes a conveyor belt, one end of which is provided with a drive roller that drives the conveyor belt to rotate, and the other end of which is provided with a driven roller that supports the conveyor belt. Both the drive roller and the driven roller are rotatably connected to the frame. The frame is provided with a transmission mechanism that drives the drive roller to rotate. The tray is a rectangular box structure with an opening on one side, and the opening side of the tray faces the seedling box.

[0007] Preferably, the transverse cutting mechanism includes a support frame fixed on the machine frame, and a plurality of vertical transverse cutters are arranged above the support frame. The transverse cutters are located between adjacent pots of the seedling tray. The transverse cutters cut the seedling tray along the moving direction of the conveyor belt. A vibrator is arranged above the support frame to drive the transverse cutters to vibrate up and down.

[0008] Preferably, the dial mechanism includes a lever located above a slide rail. The slide rail has a groove for accommodating the lever. One end of the lever is fixed to a lever shaft, and both ends of the lever shaft are mounted on the frame. One end of the lever shaft is equipped with a lever drive mechanism.

[0009] Preferably, an arc-shaped guide rail is provided between the slide rail and the top of the seedling box to support and guide the tray. The guide rail is installed on the frame and a guide groove is provided at the corresponding lever position. The bottom of the seedling box is provided with a partition to separate the adjacent pots of the seedling tray. A limiting mechanism is provided between the adjacent partitions to prevent the second row of seedling trays from sliding down.

[0010] Preferably, the limiting mechanism includes a baffle, the bottom of the seedling box is provided with a through hole for the baffle to pass through, and the bottom of the seedling box is provided with a control mechanism to drive the baffle to insert into or slide out of the seedling box.

[0011] Preferably, the longitudinal cutting mechanism includes a longitudinal cutter, which is mounted on a cutter shaft and rotatably connected to the frame. The frame is equipped with a transmission mechanism that drives the cutter shaft to rotate. The longitudinal cutter is located inside the seedling gate and works with a partition to cut the seedling tray.

[0012] Preferably, the bottom of the seedling gate beam is provided with a guide plate to restrict the movement trajectory of the seedling pot, and the seedling receiving bucket is located below the guide plate.

[0013] Preferably, the end of the slide rail is provided with a guide rod for collecting empty trays, and a collection platform for collecting empty trays is provided below the guide rod, with the collection platform mounted on the frame.

[0014] The seedling supply method based on the above-mentioned seedling supply device for a potted seedling transplanter using a decomposable seedling tray includes the following steps:

[0015] S1. Place the seedling trays inside the pallet, and then place the pallet on the conveyor belt;

[0016] S2. Start the conveyor belt and vibrator. The conveyor belt drives the tray to move. As the tray moves on the conveyor belt, the transverse cutter cuts the seedling tray transversely, and the seedling tray is divided into several rows.

[0017] S3. The seedling trays, after being cut, slide onto the slide rails driven by the conveyor belt and the trays. They continue to move along the slide rails under the push of the subsequent trays. When the first tray touches the tray position switch, the control conveyor belt and vibrator stop moving, and the transmission mechanism that drives the lever shaft to rotate is started, driving the lever shaft to rotate. The lever rotates upward, lifting the tray during the rotation. The tray moves along the guide rail, and the open end of the tray aligns with the top opening of the seedling box. The seedling trays inside the tray slide into the seedling box under the action of gravity.

[0018] S4. The transmission mechanism of the lever shaft reverses, and the lever drives the empty tray back to the slide rail;

[0019] S5. After completing the horizontal cutting, the first row of seedling trays slides to the bottom of the seedling box and is arranged in sequence inside the seedling box. The cylinder, which is the control mechanism, drives the baffle to extend. The baffle is located between the first and second rows of pots. The transmission mechanism of the longitudinal cutter is started, which drives the longitudinal cutter to rotate. The longitudinal cutter cooperates with the partition on the seedling box to cut the pots located at the seedling gate. The cut seedlings with pots fall into the receiving hopper through the seedling gate and the guide plate and are sent into the planting device of the transplanter.

[0020] S6. Start the moving component. The moving component drives the seedling box to move horizontally along the seedling gate beam, so that the next pot is facing the seedling gate. The longitudinal cutter rotates and cuts the pots in turn. Until the first row of pots is completely cut, the seedlings fall into the seedling receiving hopper through the seedling gate in turn. The seedling box limit switch detects the position of the seedling box, the cylinder retracts, the cylinder drives the baffle to slide out of the seedling box, the second row of seedling trays slides down into the seedling gate beam, the cylinder extends, and the baffle continues to block the subsequent seedling trays. The seedling box moves back and forth until the seedling trays in the seedling box are cut.

[0021] S7. Simultaneously with S5 and S6, after the lever resets, the conveyor belt and vibrator restart, the trays on the conveyor belt continue to move, completing the transverse cutting of the next batch of seedling trays, and at the same time, the empty trays are pushed into the collection platform for collection through the guide rod.

[0022] S8. Move the pallet on the conveyor belt onto the slide rail, and repeat S3-S7.

[0023] The advantages and positive effects of the seedling supply device and method for the potted seedling transplanter based on the decomposable seedling tray described in this invention are as follows:

[0024] 1. The present invention has a transverse cutter above the conveyor belt, which completes the transverse cutting of the seedling tray during the movement of the seedling tray, which facilitates the subsequent cutting process of the seedling tray.

[0025] 2. A lever is installed on the slide rail. The lever transfers the seedling tray into the seedling box and separates it through the baffle and partition inside the seedling box, which is conducive to the cutting of individual pots.

[0026] 3. The longitudinal cutting blade on the seedling gate beam can cut individual seedlings into individual pots, allowing the seedlings to fall into the seedling receiving hopper in an orderly manner, realizing the cutting of seedlings and automatic seedling supply, thus improving the efficiency of seedling supply and transplanting.

[0038] Example

[0039] like Figure 1 , Figure 2As shown. A seedling supply device for a potted seedling transplanter based on a decomposable seedling tray includes a frame 1, which can be fixedly mounted on the transplanter as needed. A conveying mechanism for the conveying tray 3 is provided on the frame 1. The conveying mechanism includes a conveyor belt 2, with a drive roller at one end of the conveyor belt 2 to drive its rotation, and a driven roller at the other end to support it. The conveyor belt 2 is wound around the drive roller and the driven roller. Both the drive roller and the driven roller are rotatably connected to the frame 1 via bearings. A transmission mechanism is provided on the frame 1 to drive the drive roller to rotate. The transmission mechanism drives the conveyor belt 2 to move via the drive roller and the driven roller, thereby moving the tray 3 above the conveyor belt 2. The transmission mechanism can be configured as a motor as needed. The conveyor belt 2 can be selected from existing belt conveyors 2, nylon conveyors 2, or steel mesh conveyors 2, etc., as needed.

[0040] like Figure 3 As shown. Tray 3 is a rectangular box structure with an opening on one side, and seedling tray 4 is located inside tray 3. The size of tray 3 is slightly larger than the size of seedling tray 4, so that seedling tray 4 fits perfectly inside tray 3. The opening side of tray 3 faces the seedling box 13, which facilitates the transfer of seedling tray 4 into seedling box 13.

[0041] A transverse cutting mechanism is installed above the conveyor mechanism to slit the seedling trays 4 laterally. The transverse cutting mechanism includes a support 9, which is fixed to the frame 1. Several vertical transverse cutters 11 are installed above the support 9, positioned between adjacent pots 27 of the seedling trays 4. The transverse cutters 11 slit the seedling trays 4 along the moving direction of the conveyor belt 2, dividing the seedling trays 4 into several rows. A vibrator 10 is installed above the support 9 to drive the transverse cutters 11 to vibrate, facilitating the cutting of the seedling trays 4.

[0042] like Figure 6 As shown, the seedling tray 4 is a structure consisting of several rows and columns of pots 27, each containing one seedling. The seedling tray 4 is a single unit and is made of readily available biodegradable materials. The seedling tray 4 is divided into several rows using a transverse cutter 11.

[0043] One end of the conveying mechanism is equipped with a slide rail 5 that supports the tray 3, and the conveying mechanism sends the tray 3 onto the slide rail 5. A seedling box 13 for storing seedling trays 4 is provided on one side of the slide rail 5, and a dial mechanism for sending the seedling trays 4 into the seedling box 13 is provided on the slide rail 5.

[0044] like Figure 4As shown. The dial mechanism includes a lever 6, which has an L-shaped structure. The lever 6 is located above the slide rail 5, and the slide rail 5 has a guide groove to accommodate the lever 6. The height of the lever 6 is not higher than the height of the slide rail 5 to avoid the lever 6 obstructing the movement of the tray 3 on the slide rail 5. One end of the lever 6 is fixed to the lever shaft 8, and both ends of the lever shaft 8 are mounted on the frame via bearings. A lever drive mechanism 7 is provided at one end of the lever shaft, and the lever drive mechanism 7 is fixed to the frame 1. The lever drive mechanism 7 can drive the lever shaft 8 to rotate, and the lever 6 lifts the tray 3 from the slide rail 5 until it is aligned with the upper end of the seedling box. The lever drive mechanism 7 can be configured as a motor as needed.

[0045] An arc-shaped guide rail 12 is provided between the slide rail 5 and the top of the seedling box 13 to support and guide the tray 3. One end of the guide rail 12 is fixed to the slide rail 5. The center of the guide rail 12 is located on the axis of the connecting shaft 8, so that the tray 3 is stably connected to the top opening of the seedling box 13 under the action of the lever 6. The seedling tray 4 inside the tray 3 enters the seedling box 13 through the top opening of the seedling box 13.

[0046] like Figure 5 As shown. The bottom of the seedling box 13 is provided with several partitions 15 that separate adjacent pots 27 of the seedling tray 4. The partitions 15 are located between adjacent pots 27, dividing adjacent pots 27 and subsequently dividing subsequent adjacent pots 27. The top of the partition 15 is conical to facilitate the division of adjacent pots 27.

[0047] A limiting mechanism is provided between adjacent partitions 15 to prevent the second row of seedling trays 4 from sliding down. The limiting mechanism includes a baffle 16, and the bottom of the seedling box 13 is provided with a through hole for the baffle 16 to pass through. The baffle 16 is slidably connected to the seedling box 13. The bottom of the seedling box 13 is provided with a cylinder 17 that drives the baffle 16 to insert or slide out of the seedling box 13. The extension and retraction of the cylinder 17 drives the baffle 16 to insert or slide out of the seedling box 13, thereby blocking the second row of seedling trays 4 or causing the second row of seedling trays 4 to slide down to the bottom of the seedling box 13.

[0048] The bottom outlet end of the seedling box 13 is equipped with a seedling gate beam 20, which is fixedly mounted on the frame 1. The seedling gate beam 20 has an L-shaped structure, with a partition plate 15 protruding from the bottom end of the seedling box 13 and inserted into the seedling gate beam 20. The seedling gate beam 20 is equipped with a seedling gate through which the seedling pots 27 pass. The size of the seedling gate is slightly larger than the size of the seedlings, so that the seedlings can slide through the seedling gate. The frame 1 is equipped with a seedling transfer mechanism 14 that drives the seedling box 13 to move horizontally along the seedling gate beam 20. The seedling transfer mechanism 14 can be an existing screw and nut pair, electric cylinder, hydraulic cylinder, or pneumatic cylinder, as long as it can drive the seedling box 13 to move horizontally along the seedling gate beam 20. During the horizontal movement of the seedling box 13, the outermost seedling pots 27 of the first row inside the seedling box 13 are aligned with the seedling gate of the seedling gate beam 20. The seedlings of the first row are cut sequentially under the action of the seedling transfer mechanism 14 and sent out through the seedling gate.

[0049] A longitudinal cutting mechanism is installed at the seedling gate to cut the pots 27. The longitudinal cutting mechanism includes a longitudinal cutter 18, which is fixedly mounted on a cutter shaft 19. The cutter shaft 19 is rotatably connected to the frame 1 via bearings. The frame 1 is equipped with a transmission mechanism that drives the cutter shaft 19 to rotate. The transmission mechanism can be configured as a motor as needed. When the longitudinal cutter 18 rotates through the seedling gate, it is located inside the seedling gate and between two adjacent partitions 15. The transmission mechanism drives the longitudinal cutter 18 to rotate via the cutter shaft 19. The longitudinal cutter 18 cooperates with the partitions 15 to cut the pots 27, cutting each row of pots 27 into individual seedlings.

[0050] Below the seedling gate beam 20, a seedling receiving hopper 22 is provided, with each seedling receiving hopper 22 corresponding to a seedling gate. The seedling receiving hopper 22 is fixedly mounted on the frame 1 and connected to the transplanting device of the transplanter. At the bottom of the seedling gate beam 20, a guide plate 21 is provided to guide the seedling pot 27. The top of the guide plate 21 is fixed to the seedling gate beam 20, and the seedling receiving hopper 22 is positioned below the guide plate 21. The seedlings slide through the guide plate 21 into the seedling receiving hopper 22 and are then fed into the transplanting device of the transplanter to complete the seedling transplanting.

[0051] A tray position switch 25 is installed at a position flush with the outer end of the slide rail 5 and the seedling box 13. The tray position switch 25 is used to detect the position of the tray 3. A seedling box limit switch 26 is fixedly installed at each end of the seedling gate beam 20. The seedling box limit switch 26 is used to detect the position of the seedling box 13. The tray position switch 25 and the seedling box limit switch 26 can be selected from existing photoelectric switches or limit switches as needed.

[0052] The end of the slide rail 5 is fixedly provided with a guide rod 23 for guiding the empty tray 3. Below the guide rod 23 is a collection platform 24 for collecting the empty tray 3. The collection platform 24 is set on the frame 1.

[0053] Electrical components such as tray position switch 25, seedling box limit position switch 26, motor, vibrator 10, and cylinder 17 are all electrically connected to the controller using existing technology as needed.

[0054] The seedling supply method of the above-mentioned seedling transplanter based on a decomposable seedling tray includes the following steps:

[0055] S1. Place the seedling tray inside the pallet, and then place the pallet on the conveyor belt.

[0056] S2. Start the conveyor belt and vibrator. The conveyor belt drives the tray to move. As the tray moves on the conveyor belt, the transverse cutter cuts the seedling tray transversely, and the seedling tray is divided into several rows.

[0057] S3. The seedling trays, after being cut, slide onto the slide rails driven by the conveyor belt and the pallets. They continue to move along the slide rails under the push of the subsequent pallets. When the first pallet touches the pallet position switch, the control conveyor belt and vibrator stop moving, and the transmission mechanism that drives the lever shaft to rotate starts, driving the lever shaft to rotate. The lever rotates upward, lifting the pallet during the rotation. The pallet moves along the guide rail, and the open end of the pallet aligns with the top opening of the seedling box. The seedling trays inside the pallet slide into the seedling box under the action of gravity.

[0058] S4. The transmission mechanism of the lever shaft reverses, and the lever drives the empty tray back to the slide rail.

[0059] S5. After completing the horizontal cutting, the first row of seedling trays slides to the bottom of the seedling box and is arranged in sequence inside the seedling box. The cylinder, which serves as the control mechanism, drives the baffle to extend. The baffle is located between the first and second rows of seedlings. The transmission mechanism of the longitudinal cutter is activated, which drives the longitudinal cutter to rotate. The longitudinal cutter cooperates with the partition on the seedling box to cut the seedling trays located at the seedling gate. The cut seedlings with trays fall into the seedling receiving hopper through the seedling gate and the guide plate and are sent into the planting device of the transplanter.

[0060] S6. Start the moving component. The moving component drives the seedling box to move horizontally along the seedling gate beam, so that the next pot is facing the seedling gate. The longitudinal cutter rotates and cuts the pots in sequence. Until the first row of pots is completely cut, the seedlings fall into the receiving hopper through the seedling gate in sequence. The seedling box limit switch detects the position of the seedling box, the cylinder retracts, and the cylinder drives the baffle to slide out of the seedling box. The second row of seedling trays slides down into the seedling gate beam. The cylinder extends, and the baffle continues to block the subsequent seedling trays. The seedling box moves back and forth until the seedling trays in the seedling box are completely cut.

[0061] S7. Simultaneously with S5 and S6, after the lever resets, the conveyor belt and vibrator restart, and the trays on the conveyor belt continue to move, completing the transverse cutting of the next batch of seedling trays. At the same time, the empty trays are pushed into the collection platform for collection via the guide rod.

[0062] S8. Move the pallet on the conveyor belt onto the slide rail, and repeat S3-S7.

[0063] Therefore, the seedling supply device of the potted seedling transplanter based on the decomposable seedling tray described in this invention can solve the problem that the existing traditional potted seedling transplanter based on the seedling tray cannot achieve automatic seedling supply and has low transplanting efficiency.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.

The cut seedlings with pots fall into the receiving hopper through the seedling gate and the guide plate and are sent into the planting device of the transplanter. S6. Start the moving component. The moving component drives the seedling box to move horizontally along the seedling gate beam, so that the next pot is facing the seedling gate. The longitudinal cutter rotates and cuts the pots in turn. Until the first row of pots is completely cut, the seedlings fall into the seedling receiving hopper through the seedling gate in turn. The seedling box limit switch detects the position of the seedling box, the cylinder retracts, the cylinder drives the baffle to slide out of the seedling box, the second row of seedling trays slides down into the seedling gate beam, the cylinder extends, and the baffle continues to block the subsequent seedling trays. The seedling box moves back and forth until the seedling trays in the seedling box are cut. S7. Simultaneously with S5 and S6, after the lever resets, the conveyor belt and vibrator restart, the trays on the conveyor belt continue to move, completing the transverse cutting of the next batch of seedling trays, and at the same time, the empty trays are pushed into the collection platform for collection through the guide rod. S8. Move the pallet on the conveyor belt onto the slide rail, and repeat S3-S7.
