[0021] Specifically, when the seedlings need to be placed in the placing bin 2, the power output end of the lifting device 5 drives the upper locking piece 62 to move upward, and the lower locking piece 62 drives the guide plate 6 to move upward. Since the end of the lever 4 is arranged in the arc-shaped slot 61, when the guide plate 6 moves upward, the end of the lever 4 slides downward in the arc-shaped slot 61, the lever 4 drives the opening and closing plate 3 to rotate upward, and then the bottom of the placing bin 2 is closed. At this time, the wedge-shaped block 12 is inserted into the wedge-shaped slot 63, the upper locking piece 11 and the lower locking piece 62 are locked together, and the power output end of the lifting device 5 returns to the original position. The opening and closing plate 3 is kept in the closed state by the upper locking piece 11 and the lower locking piece 62. At this time, the seedlings can be placed in the placing bin 2.

[0022] When the transport vehicle 1 carries the seedlings to the target position, the wedge-shaped block 12 is separated from the wedge-shaped slot 63, the upper locking piece 11 and the lower locking piece 62 are separated, the guide plate 6 slides downward under the action of gravity, the end of the lever 4 slides upward in the arc-shaped slot 61, the lever 4 drives the opening and closing plate 3 to rotate downward, and then the bottom of the placing bin 2 is opened. At this time, the seedlings in the placing bin 2 can fall into the target area.

[0023] Compared with the prior art in which multiple components need to be cooperated to open the opening and closing plate 3, the application has a simple structure, a lower failure rate, a convenient opening mode, and greatly improved production efficiency under the action of gravity.

[0024] The power output end of the lifting device 5 can be provided with a flexible body for buffering the vibration when the guide plate 6 falls. The lifting device 5 can adopt a gas cylinder or an electric cylinder.

[0025] In a feasible embodiment, a first spring 13 is arranged between the wedge-shaped block 12 and the upper locking piece 11, the first spring 13 is used to drive the wedge-shaped block 12 to be inserted into the wedge-shaped slot 63, the upper locking piece 11 is provided with an electromagnetic block 14 at a position corresponding to the position of the wedge-shaped block 12, and the electromagnetic block 14 is used to be electrified to drive the wedge-shaped block 12 to be separated from the wedge-shaped slot 63. In the embodiment, the wedge-shaped block 12 has a slope and a clamping surface, and the elastic force of the first spring 13 is used to pull the wedge-shaped block 12 close to the upper locking piece 11. When the lower locking piece 62 moves upward, the wedge-shaped block 12 rotates away from the upper locking piece 11 due to the action of the slope. When the lower locking piece 62 moves to the target position, the clamping surface enters the clamping slot, and then the upper locking piece 11 and the lower locking piece 62 are fixed. When the opening and closing plate 3 needs to be opened, the electromagnetic block 14 is electrified, the wedge-shaped block 12 repels the magnetic pole of the electromagnetic block 14. Under the action of the magnetic repulsion, the wedge-shaped block 12 rotates away from the upper locking block, and is separated from the wedge-shaped slot 63, so as to release the lower locking block. In the embodiment, the electromagnetic block only needs to be electrified at the moment of releasing the lower locking block, which greatly reduces the power consumption required for maintaining the magnetic force of the electromagnetic block.

[0026] Further, the wedge-shaped block 12 is provided with a ball on the clamping surface, and the ball is in abutment with the wedge-shaped slot 63. The ball can convert the sliding friction between the clamping surface and the wedge-shaped slot 63 into rolling friction, thereby reducing the current required by the electromagnet.

[0027] In an embodiment, the guide plate 6 is provided with an upper pin 64, the transfer trolley 1 is provided with a lower pin 15, the lower pin 15 is below the upper pin 64, a second spring 16 is connected between the upper pin 64 and the lower pin 15, and the second spring 16 is used to pull the guide plate 6 to move downward. Under the action of the guide plate 6 and the elastic force of the second spring 16, the opening speed of the opening and closing plate 3 is further increased.

[0028] In an embodiment, the end of the lever 4 is provided with a pulley 41, and the pulley 41 is used to roll in the arc-shaped slot 61. The pulley 41 can convert the sliding friction between the lever 4 and the arc-shaped slot 61 into rolling friction, thereby improving the smoothness of the guide plate 6 during the up and down movement.

[0029] In an embodiment, the end of the pulley 41 is provided with a limiting ring 42, and the limiting ring 42 is used to limit the lever 4 from separating from the arc-shaped slot 61 along the axial direction.
