The front stop 2 and the rear stop 3 are both fixedly installed on the main frame 1, and the front stop 2 and the rear stop 3 form a guide groove 5 to limit the seedling tray. The two ends of the guide groove 5 are respectively provided with an inlet and an outlet. The inlet is connected to the seedling conveying mechanism, and the outlet is provided with a drive roller 6 to send the seedling tray out of the guide groove 5. The front stop 2 and the rear stop 3 are respectively provided with a plurality of seedling removal grooves 7. The striking pin 4 is movably installed on the main frame 1 and is connected to a drive structure. Each seedling removal groove 7 corresponds to a striking pin 4. The drive structure can drive the striking pin 4 to move toward or away from the seedling removal groove 7. In this embodiment, the front stop 2 and the rear stop 3 can each include a plurality of parallel baffles 19. The plurality of baffles 19 are connected and fixed by a fixing rod, and the seedling removal groove 7 is formed between two adjacent baffles 19.

[0029] The rice rolling mechanism includes an unwinding roller 8 and a winding roller 9 rotatably mounted on the main frame 1, and a rice rolling film 10 wound on the unwinding roller 8 and the winding roller 9. Before rolling the rice, the rice rolling film 10 is wound on the unwinding roller 8, and one end of it is connected to the winding roller 9. The winding roller 9 is connected to a first drive motor 11 that drives it to rotate. The first drive motor 11 drives the winding roller 9 to move, thereby driving the winding roller 9 and the unwinding roller 8 to rotate synchronously, so that the unwinding roller 8 releases the rice rolling film 10 and winds it onto the winding roller 9.

[0030] The seedling tray recycling mechanism includes a basket 12 located below the outlet of the guide trough 5, which can collect and stack the seedling trays sent out from the outlet of the guide trough 5 on the basket 12.

[0031] This utility model discloses an automatic rice seedling rolling machine, which includes a seedling conveying mechanism, a seedling removal mechanism, a seedling rolling mechanism, and a seedling tray recycling mechanism. The seedling conveying mechanism sends the seedling tray with seedlings into the guide groove 5. Then, the drive structure drives the impact pin 4 to move towards the seedling tray. Under the impact of the impact pin 4, the seedlings are pushed out of the seedling tray holes. The pushed-out seedlings fall onto the seedling rolling film 10 through the seedling removal groove 7. Finally, the seedling rolling film 10 with seedlings is rolled up by the winding roller 9, thereby realizing the automatic removal and rolling of seedlings. In addition, after the seedlings are removed, the seedling tray is pushed out of the guide groove 5 by the drive roller 6 and uniformly collected and placed in the seedling tray recycling mechanism. In the whole operation, there is no need for manual removal of the seedling trays. It can realize the automatic removal of seedlings and pack the seedlings into bundles for subsequent sowing, thereby improving the sowing efficiency of seedlings and reducing damage to seedlings.

[0032] In one specific embodiment of this application, the seedling conveying mechanism may include an active roller 13, a driven roller 14, and a conveyor belt 15. The active roller 13 and the driven roller 14 are rotatably mounted on the main frame 1. Specifically, in order to improve the stability of the installation of the active roller 13 and the driven roller 14, the main frame 1 may be provided with bearings that rotate with both ends of the active roller 13 and the driven roller 14. The active roller 13 is connected to a second drive motor 16. The conveyor belt 15 is wound in a ring around the active roller 13 and the driven roller 14, and its two ends are respectively connected to the active roller 13 and the driven roller 14. The active roller 13 is driven to rotate by the second drive motor 16, thereby driving the conveyor belt 15 to rotate cyclically.

[0033] Furthermore, in this embodiment, a plurality of protruding ribs 17 are evenly distributed along the length of the conveyor belt 15. The protruding ribs 17 are elongated and perpendicular to the conveying direction of the conveyor belt 15. A groove is left between the two rows of seedling tray holes at the bottom of the seedling tray. By setting the protruding ribs 17 to engage with the groove, the stability of the seedling tray placed on the conveyor belt 15 can be ensured, so that the conveyor belt 15 can transport the seedling tray.

[0034] In this embodiment, the drive roller 6 can be connected to the drive drum 13 via a belt 18, thereby enabling the drive roller 6 and the drive drum 13 to rotate synchronously.

[0035] To improve the stability of the striking pins 4 during movement, a guide block 20 is provided on the main frame 1. The guide block 20 has the same number of guide holes as the striking pins 4, and several striking pins 4 are slidably installed in the corresponding guide holes. In this embodiment, the drive structure may include a third drive motor 21 and a crank 22 connecting the third drive motor 21 and the striking pins 4. By connecting the third drive motor 21 and the striking pins 4 through the crank 22, the rotational motion of the motor output shaft can be converted into the back-and-forth motion of the striking pins 4, thereby continuously inserting and purging the seedling tray.

[0036] In one preferred embodiment of this application, a sliding plate 23 is provided below the seedling removal trough 7. The upper end of the sliding plate 23 is fixedly connected to the frame body, and the lower end of the sliding plate 23 is inclined downward toward the side of the winding roller shaft 9 and extends to the seedling roll film 10, so that the seedlings that are knocked off the seedling tray fall onto the sliding plate 23 through the seedling removal trough 7 and slide down the sliding plate 23 onto the seedling roll film 10, thereby ensuring that the seedlings can fall smoothly onto the seedling roll film 10.

[0037] In a more preferred embodiment of this application, dampers 24 are connected to both ends of the unwinding roller shaft 8. The dampers 24 can provide a certain damping to the unwinding roller shaft 8 so that the unwinding roller shaft 8 will not rotate without external force.
