Abstract
Description
Technical Field
[0001] This utility model relates to the field of seedling tray conveying technology, and in particular to a seedling tray conveying mechanism for seedling sowing. Background Technology
[0002] The seedling tray conveying device can transport seedling trays to the target location, avoiding the time-consuming and inefficient manual handling and significantly increasing the seedling yield per unit time. However, it is not convenient to store the seedling trays after transport, and it occupies a large area. It is not suitable for the transfer and use of seedling trays. It also cannot restrict light by stacking (darkening treatment) to inhibit the excessive growth of seedling stems and leaves, promote the preferential development of roots, and form robust seedlings with "short buds and strong roots", laying the foundation for subsequent transplanting.
[0003] However, existing technologies, such as Chinese Publication No. CN221139813U, "A Seedling Tray Conveying Mechanism for Seedling Sowing," disclose a seedling tray conveying mechanism for seedling sowing. This mechanism includes a frame, with a drive roller and a driven roller connected internally via bearings. Both the drive roller and the driven roller have pulleys fixed externally. A conveyor belt drives the pulleys of the drive roller and the driven roller. A fixed frame is fixed to the bottom outer wall of the frame, and a roller frame is slidably connected inside the fixed frame. A tension roller is connected between the inner walls of both sides of the roller frame via bearings, and the tension roller is located inside the conveyor belt. A threaded sleeve is welded to the bottom outer wall of the fixed frame, and a screw rod is threadedly connected inside the threaded sleeve. The top end of the screw rod is connected to the roller frame via a bearing, and a handwheel is welded to the bottom end of the screw rod. This invention uses the rotation of the screw rod to drive the roller frame and tension roller downwards, thus tightening the slack conveyor belt. This makes the maintenance of the seedling tray conveying mechanism more convenient and the seedling tray conveying more stable.
[0004] However, this device does not have a transmission and stacking structure, so it cannot automatically stack the seedling trays transported to the target location. It cannot solve the problem of "separation of transmission and stacking" in the traditional seedling raising process. It is not suitable for the multiple requirements of efficiency, accuracy and space for large-scale seedling raising. It requires manual stacking and placement, which increases the labor cost. Utility Model Content
[0005] The purpose of this invention is to address the problem in the existing technology that the seedling trays transported to the target location cannot be automatically stacked, which fails to solve the pain point of "separation of transmission and stacking" in the traditional seedling raising process. This makes it unsuitable for the multiple requirements of efficiency, precision and space for large-scale seedling raising, and requires manual stacking, which increases labor costs.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a seedling tray conveying mechanism for seedling raising and sowing, comprising a pressure plate, two support shells fixedly connected to the top of the pressure plate, each support shell having a limiting groove, a power rod rotatably connected inside the two support shells and extending out one end, a crank fixedly sleeved on the outer surface of the power rod, a connecting rod rotatably connected to the end of the crank away from the power rod, a shaft block rotatably connected to the end of the connecting rod away from the crank, a lifting plate fixedly connected to the top of the shaft block, limiting blocks fixedly connected to both sides of the lifting plate, the outer surface of the limiting blocks being movably embedded in the limiting groove, a rotating component provided at the end extending from the power rod, the power rod rotating inside the support shell, the crank rotating with the power rod driving one end of the connecting rod, the other end of the connecting rod pushing the lifting plate through the shaft block, so that the lifting plate and the outer limiting blocks rise and fall along the groove opening direction of the limiting groove.
[0007] In a preferred embodiment, the rotating assembly includes a force-applying handle, one side of which is fixedly connected to one end of the power rod extending outwards. An electric push rod is rotatably connected to the end of the force-applying handle away from the power rod. The end of the electric push rod away from the force-applying handle is rotatably connected to the top of the pressure plate. When the electric push rod performs work, it drives the force-applying handle to rotate, and in turn drives the power rod to rotate inside the support shell.
[0008] In a preferred embodiment, the rotating assembly further includes a first mounting sleeve, one side of which is fixedly connected to one side of the support shell. A servo motor is fixedly embedded in the inner surface of the first mounting sleeve. The output end of the servo motor is fixedly connected to one end of the power rod. Rotation of the power rod can also start the external power supply of the servo motor. The servo motor is fixed to one side of the support shell through the first mounting sleeve. When the servo motor is powered on, it will also drive the power rod to rotate inside the two support shells.
[0009] In a preferred embodiment, a bearing seat is fixedly connected to the top of the lifting plate, and a guide plate is rotatably connected inside the bearing seat. The guide plate maintains the same tilt angle as the inclined main housing, which facilitates the seedling tray to flow back into the area above the guide plate.
[0010] In a preferred embodiment, the bottom of the guide plate is provided with a lifting strip, both ends of which are fixedly connected to the inner side of the support shell. The top of the guide plate is fixedly connected with a positioning strip. When the lifting plate descends, the guide plate will rotate inside the bearing after contacting the lifting strip, so that the guide plate continues to maintain the same tilt angle with the inclined main body shell.
[0011] In a preferred embodiment, a plurality of fixing rods are fixedly connected to the inner surface of the support shell, and two rotating blocks are rotatably connected to the outer surface of the fixing rods. Stop rods are fixedly connected to the top of the two rotating blocks, and the two ends of the plurality of stop rods are fixedly connected to the inner surface of the pressure plate. The seedling tray will contact the rotating blocks and allow the rotating blocks to continue rotating on the outer surface of the fixing rods. When the seedling tray is above the rotating blocks, under the action of gravity and the limiting action of the stop rods on the rotating blocks, the seedling tray will be fixed above the plurality of rotating blocks.
[0012] In a preferred embodiment, a plurality of support rods are fixedly connected to the top of the pressure plate, and an inclined main housing is fixedly connected to the top of the plurality of support rods. Two transmission rollers are rotatably connected inside the inclined main housing, and a transmission belt is drivenly connected to the outer surface of the two transmission rollers. The inclined main housing is fixed to the top of the pressure plate by the support rods.
[0013] In a preferred embodiment, a second mounting sleeve is fixedly connected to one side of the inclined main housing. A transmission motor is fixedly embedded on the inner surface of the second mounting sleeve. The output end of the transmission motor is fixedly connected to one end of the transmission roller. The transmission motor is fixed to one side of the inclined main housing through the second mounting sleeve. When the transmission motor is powered on, it will drive the transmission roller to rotate inside the inclined main housing. Under the transmission action of the transmission belt, it will drive the seedling tray to be transported and fall into the guide plate above the inclined main housing at the same inclination angle and inside the positioning strip.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] This invention features a device with a transmission and stacking structure that automatically stacks seedling trays transported to the target location. This solves the problem of "separation between transmission and stacking" in the traditional seedling raising process, making it suitable for the multiple demands of large-scale seedling raising in terms of efficiency, precision, and space. It eliminates the need for manual stacking and reduces labor costs. Attached Figure Description

The outer surface of the limiting blocks 9 is movably embedded inside the limiting grooves 3. A rotating assembly is provided at the extended end of the power rod 4. The rotating assembly includes a force-applying handle 10. One side of the force-applying handle 10 is fixedly connected to the extended end of the power rod 4. An electric push rod 11 is rotatably connected to the end of the force-applying handle 10 away from the power rod 4. The end of the electric push rod 11 away from the force-applying handle 10 is rotatably connected to the top of the pressure plate 1. The top of the lifting plate 8 is fixedly... A bearing seat 14 is fixedly connected, and a guide plate 15 is rotatably connected inside the bearing seat 14. A lifting strip 16 is provided at the bottom of the guide plate 15, and both ends of the lifting strip 16 are fixedly connected to the inner side of the support shell 2. A positioning strip 17 is fixedly connected to the top of the guide plate 15. Multiple fixing rods 18 are fixedly connected to the inner surface of the support shell 2. Two rotating blocks 19 are rotatably connected to the outer surface of the fixing rods 18. Stop rods 20 are fixedly connected to the top of the two rotating blocks 19.

A transmission motor 26 is fixedly embedded in the inner surface of the second mounting sleeve 25. The output end of the transmission motor 26 is fixedly connected to one end of the transmission roller 23.
[0025] In this embodiment, the seedling tray to be transported is first placed above the inclined main housing 22 and the conveyor belt 24. The inclined main housing 22 is fixed to the top of the pressure plate 1 by the support rod 21. The external power supply of the transmission motor 26 is turned on. The transmission motor 26 is fixed to one side of the inclined main housing 22 by the second mounting sleeve 25. After the transmission motor 26 is powered on, it will drive the transmission roller 23 to rotate inside the inclined main housing 22. Under the transmission action of the conveyor belt 24, it will drive the seedling tray to be transported and fall into the guide plate 15 with the same inclination angle as the inclined main housing 22 and inside the positioning strip 17. Then, according to the identification and built-in existing technology program, the electric push rod 11 is made to do work. The electric push rod 11 will drive the force application handle 10 to rotate and drive the power rod 4 to rotate inside the support housing 2. The crank 5 that follows the rotation of the power rod 4 will drive one end of the connecting rod 6, and the other end of the connecting rod 6 will... The lifting plate 8 is pushed by the shaft block 7, so that the lifting plate 8 and the outer limiting block 9 move up and down along the slotting direction of the limiting groove 3, so that the guide plate 15 rotates inside the shaft seat 14 and keeps the seedling tray of the guide plate 15 in a horizontal state. Then the lifting plate 8 continues to rise, and the seedling tray will contact the rotating block 19, and the rotating block 19 will continue to rotate on the outer surface of the fixing rod 18. When the seedling tray is above the rotating block 19, under the action of gravity and the limiting action of the stop rod 20 on the rotating block 19, the seedling tray will be fixed above multiple rotating blocks 19. It can also continue to push the seedling tray above by the next seedling tray to continue to push forward. When the lifting plate 8 descends, the guide plate 15 will rotate inside the shaft seat 14 after contacting the lifting bar 16, so that the guide plate 15 continues to maintain the same tilt angle with the inclined main body housing 22, so that the seedling tray can flow into the top of the guide plate 15 again.
[0026] Example 2, please refer to Figures 1 to 5 The rotating assembly also includes a first mounting sleeve 12, one side of which is fixedly connected to one side of the support shell 2. A servo motor 13 is fixedly embedded on the inner surface of the first mounting sleeve 12, and the output end of the servo motor 13 is fixedly connected to one end of the power rod 4.
[0027] In this embodiment, rotating the power rod 4 can also activate the external power supply of the servo motor 13. The servo motor 13 is fixed to one side of the support shell 2 by the first mounting sleeve 12. After the servo motor 13 is powered on, it will also drive the power rod 4 to rotate inside the two support shells 2.
[0028] Working principle: First, the seedling trays to be transported are placed above the inclined main housing 22 and the conveyor belt 24. The inclined main housing 22 is fixed to the top of the pressure plate 1 by the support rod 21. The external power supply of the transmission motor 26 is turned on. The transmission motor 26 is fixed to one side of the inclined main housing 22 by the second mounting sleeve 25. After the transmission motor 26 is powered on, it will drive the transmission roller 23 to rotate inside the inclined main housing 22. Under the transmission action of the conveyor belt 24, it will drive the seedling tray to be transported and fall into the guide plate 15 with the same inclination angle as the inclined main housing 22 and inside the positioning strip 17. Then, according to the recognition and built-in existing technology program, the electric push rod 11 will work. The electric push rod 11 will drive the force application handle 10 to rotate and drive the power rod 4 to rotate inside the support housing 2. The crank 5 that follows the rotation of the power rod 4 will drive one end of the connecting rod 6. The other end of the connecting rod 6 will push the lifting plate 8 through the shaft block 7, so that the lifting plate 8 and the outer limit block 9 will rise and fall along the slotting direction of the limit groove 3. This causes the guide plate 15 to rotate inside the bearing seat 14, keeping the guide plate 15 and the seedling tray in a horizontal position. Then, the lifting plate 8 continues to rise, and the seedling tray will contact the rotating block 19, causing the rotating block 19 to continue rotating on the outer surface of the fixing rod 18. When the seedling tray is above the rotating block 19, under the action of gravity and the limiting action of the stop rod 20 on the rotating block 19, the seedling tray will be fixed above the multiple rotating blocks 19. It is also possible to continue to push the seedling tray above it forward by pushing the next seedling tray. When the lifting plate 8 descends, the guide plate 15 will rotate inside the bearing seat 14 after contacting the lifting bar 16, so that the guide plate 15 continues to maintain the same tilt angle with the inclined main housing 22, which facilitates the seedling tray to flow back into the upper part of the guide plate 15. The rotation of the power rod 4 can also start the external power supply of the servo motor 13. The servo motor 13 is fixed to one side of the support housing 2 through the first mounting sleeve 12. After the servo motor 13 is powered on, it will also drive the power rod 4 to rotate inside the two support housings 2.
