[0027] The seedling tray conveying mechanism includes a tray frame 2, a tray 3, and a pushing assembly. The tray frame 2 is detachably fixed to the top of the main frame 1 using screws, facilitating its assembly and disassembly. One end of the tray frame 2 has a seedling tray placement area 4, and the other end has a tray collection area 5. Specifically, the seedling tray placement area 4 at one end of the tray frame 2 is fixed to the main frame 1, and the other end of the tray frame 2 extends beyond the main frame 1 to form the tray collection area 5. A support plate 6 is provided at the bottom of the seedling tray placement area 4, and the support plate 6 has a seedling drop opening 7 at the end near the tray collection area 5. The tray 3 is tilted for placing seedlings. The seedling tray is placed on a tray frame 2, which can hold multiple trays 3. The trays 3 slide in conjunction with the tray frame 2. The pushing component is installed on the top of the main frame 1 and can drive the trays 3 from the seedling tray placement area 4 toward the tray collection area 5. Specifically, the trays 3 can be tilted downwards in the pushing direction. Each tray 3 can hold a seedling tray. The seedling tray leans against the tray 3 and is supported by the support plate 6 so that the seedling tray can be stably placed on the tray 3. When the seedling tray moves to the seedling drop port 7 during the conveying process, the seedling tray will slide out from the bottom of the tray 3 under its own gravity because there is no support from the support plate 6.

[0028] The seedling tray conveying mechanism includes a stop block 8, a camshaft 9, a first drive roller shaft 10, and a second drive roller shaft 11. The stop block 8 is fixedly mounted on the main frame 1 and is provided with several seedling removal troughs 12. The first drive roller shaft 10 and the second drive roller shaft 11 are rotatably mounted on the main frame 1. The first drive roller shaft 10 is located on one side of the upper end of the stop block 8, forming a seedling tray inlet 13 with the upper end of the stop block 8. The second drive roller shaft 11 is located on one side of the lower end of the stop block 8, forming a seedling tray outlet 14 with the lower end of the stop block 8. The camshaft 9 is rotatably mounted on one side of the main frame 1 located in the middle of the stop block 8 and is connected to a motor that drives its rotation. Specifically, both the first drive roller shaft 10 and the second drive roller shaft 11 can be driven by belt drives. The structure is connected to the motor drive. The number of seedling troughs 12 is the same as the number of seedling tray holes in each row of seedling trays and their positions correspond to each other. During the rotation of the camshaft 9, the protruding part on the side farther from the rotation axis can squeeze the back of the seedling tray, while the front of the seedling tray is limited by the stop block 8, so that the seedlings on the seedling tray can be squeezed out of the seedling tray holes. In this application, the first drive roller shaft 10 and the second drive roller shaft 11 are both provided with protruding ribs 31. The protruding ribs 31 are evenly distributed around the axis of the first drive roller shaft 10 and the second drive roller shaft 11 and extend along the axial direction of the first drive roller shaft 10 and the second drive roller shaft 11. When conveying the seedling tray, the protruding ribs 31 can be inserted into the groove at the bottom of the seedling tray, thereby pushing the seedling tray to be conveyed.

[0029] The seedling blowing mechanism includes a guide trough 15 located below the seedling removal trough 12, and a blower 16 installed in the guide trough 15. Multiple guide troughs 15 can be arranged in a row, and the top of the guide trough 15 can be provided with a perforated guide plate to facilitate the seedlings falling from the seedling removal trough 12 into the guide trough 15. The blower 16 can be fixedly installed on the trough wall at one end of the guide trough 15, and the other end of the guide trough 15 is provided with a seedling throwing port. The wind force provided by the blower 16 causes the seedlings in the guide trough 15 to be dispersed and thrown out from the seedling throwing port.

[0030] The seedling tray recycling mechanism includes a basket 17 located below the seedling tray outlet 14. The basket 17 can accommodate the seedling trays sent out from the lower end of the guide trough 15 for unified collection and processing of the seedling trays after seedling removal.

The upper end of the baffles 29 is fixedly connected to the main frame 1, thereby constructing a basket structure for storing and placing seedling trays.

[0031] This utility model discloses a seedling tray inclined cam extrusion shaking and throwing device, which includes a seedling tray conveying mechanism, a seedling removal mechanism, a seedling blowing mechanism, and a seedling tray recycling mechanism. In use, seedling trays containing seedlings are placed on trays 3 in the seedling tray placement area 4. Then, a pushing component pushes the trays 3 towards the tray collection area 5. During the pushing process, the seedling trays slide through the dropping opening 7 to the seedling tray inlet 13. The trays 3 after sliding are collected and placed uniformly in the tray collection area 5. The seedling trays at the seedling tray inlet 13 are conveyed to the camshaft 9 via the first drive roller 10. The camshaft 9 is driven by a motor to rotate, causing the camshaft 9... The protrusion on the side away from the rotation axis squeezes the bottom of the seedling tray, thereby squeezing the seedlings out of the seedling holes in the seedling tray. The squeezed seedlings fall into the guide trough 15 through the seedling removal trough 12, and are dispersed and thrown by the wind provided by the fan 16 in the guide trough 15, so as to realize the seedling throwing. In addition, the seedling tray after seedling removal is transported to the seedling tray outlet 14, and is transported to the seedling tray recycling mechanism for unified collection and processing by the second drive roller 11. In the whole process, no manual seedling removal and throwing operation is required, the degree of automation is high, the seedling throwing efficiency of the seedling tray is improved, and the seedlings are not damaged during the seedling removal process, thus improving the survival rate of the seedlings.

[0032] In one embodiment of this application, the tray 3 may include a support plate 18, with side plates 19 provided on both sides of the support plate 18, so that the top of the tray 3 forms an inlet 20 for placing the seedling tray, and the bottom of the tray 3 forms an outlet 21 for the seedling tray to slide out. When placing the seedling tray, it can be placed into the tray 3 through the inlet 20, and when the seedling tray is transported to the seedling outlet 7, it can slide out through the outlet 21. Furthermore, slide rails 22 are provided on both sides of the top and bottom of the tray frame 2, and rollers 23 that cooperate with the slide rails 22 are provided at the top and bottom of the side plates 19. By setting the rollers 23 to slide with the slide rails 22, the tray 3 and the tray frame 2 are slidably connected, thereby improving the stability of the tray 3 installation.

[0033] In this application, the pushing component may include a ring-shaped chain 24 installed on the top of the main frame 1, and a transmission structure for driving the chain 24 to rotate cyclically. The transmission structure may adopt an existing sprocket transmission structure, that is, both ends of the chain 24 are connected to sprockets, the sprockets are connected to a motor, and the motor drives the sprockets to rotate, thereby driving the chain 24 to rotate. Several push plates 25 are evenly distributed around the chain 24 along its length. Rollers 23 are installed on both sides of the tray 3 through connecting rods. The push plates 25 can abut against the connecting rods, thereby pushing the tray 3 from the seedling tray placement area 4 toward the tray collection area. 5. Movement: In this embodiment, since the length of the chain 24 is only set to the seedling outlet 7, the chain 24 cannot continue to transport the tray 3 after transporting it to the seedling outlet 7. Therefore, the pushing component may also include a wheel brush 26 that drives the movement of the tray 3. The wheel brush 26 is rotatably installed at the seedling outlet 7 and is connected to the motor in the transmission structure via a belt, thereby driving the wheel brush 26 to rotate. The wheel brush 26 is in the shape of a round shaft, and multiple paddles are evenly distributed around its outer edge. By controlling the rotation of the wheel brush 26, the tray 3 at the seedling outlet 7 can be pushed toward the seedling tray collection area to facilitate the collection of the tray 3.

[0034] In one preferred embodiment of this application, the baffle 8 may include a plurality of baffles 27 arranged in parallel, the plurality of baffles 27 being connected and fixed together by a fixing rod, and the two adjacent baffles 27 forming the seedling removal trough 12.

[0035] In another preferred embodiment of this application, a guide plate 30 can be fixedly installed below the seedling inlet 7, and the guide plate 30 is inclined downward toward the seedling tray inlet 13. By providing the guide plate 30, the seedling tray sliding down from the tray 3 can be guided, so that the seedling tray can smoothly slide down to the seedling tray inlet 13.

[0036] It should be noted that after all the seedling trays on the tray frame 2 have been used to transplant the seedlings, the entire tray frame 2 can be removed from the main frame 1. Then, the seedling trays with seedlings can be placed back on the tray 3. The position of the tray 3 can be adjusted so that one tray 3 corresponds to one push plate 25. Finally, the tray frame 2 can be fixed to the main frame 1.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
