[0018] See also Figure 3 In one embodiment, a palletizing mechanism includes: a fixed frame 1, a sliding frame 4, a vertical driving member, a sliding part 10, and a linear driving member.

[0019] See also Figure 1 , Figure 2 The fixing frame 1 is placed on the ground behind the conveyor belt 3 in the tray seeder to provide installation positions for various components. Anchor bolts or weights can be used to increase its stability.

[0020] See also Figure 3 , the sliding frame 4 is connected to the fixed frame 1 by sliding up and down in the vertical direction. The vertical driving member is used to drive the sliding frame 4 to slide up and down. In one embodiment, the vertical driving member includes a first screw 7, a first motor 8, and a first guide rod 9. The first screw 7 is rotatably connected to the fixed frame 1, and its rotating shaft is in the vertical direction. The housing of the first motor 8 is fixed on the fixed frame 1 by threaded connection or welding, and the end of its output shaft is fixedly connected to the first screw 7 by welding, which is used to drive the first screw 7 to rotate. A screw nut matching the first screw 7 is provided in the sliding frame 4, and is connected to the first screw 7 through the screw nut. The first guide rod 9 is fixed to the fixed frame 1 in the vertical direction. A first through hole 5 is vertically provided on the sliding frame 4, and is slidably connected to the first guide rod 9 in the vertical direction through the first through hole 5. With this arrangement, the structure is stable and the transmission effect is good.

[0021] See also Figure 3, the sliding part 10 is connected to the sliding frame 4 by sliding along the direction approaching or moving away from the conveyor belt 3. In one embodiment, the sliding part 10 is connected to the sliding frame 4 by sliding along the direction approaching or moving away from the conveyor belt 3 in the horizontal plane. This arrangement makes the seedling tray 16 more stable and easier to keep stable when the sliding part 10 moves on the sliding part 10. In the utility model, the direction in which the conveyor belt 3 moves forward and backward is defined as the front-back direction, and further, the sliding part 10 slides along the front-back direction.

[0022] See also Figure 3 The linear drive is used to drive the sliding part 10 to slide. In one embodiment, the linear drive is a first cylinder 15. The cylinder body of the first cylinder 15 is fixed on the fixed frame 1, and the end of the output shaft is fixedly connected to the sliding part 10. This arrangement is because the sliding part 10 only needs to complete reciprocating motion between two positions, namely, connecting to the seedling tray 16 and putting down the seedling tray 16, and the cylinder is more suitable for this working condition.

[0023] See also Figure 3 An opening and closing door 11 is arranged on the front side of the sliding part 10. The opening and closing door 11 is mainly composed of two rotating plates 12, one on the left and one on the right. The rotating axes of the two rotating plates 12 are parallel, and two driving motors 13 are arranged to drive the two rotating plates 12 to rotate respectively.

[0024] See also Figure 3 The front side of the sliding part 10 is provided with an opening and closing door 11 which can be opened and closed. The opening and closing door 11 is mainly composed of two rotating plates 12, one on the left and one on the right. The rotating shafts of the two rotating plates 12 are parallel and respectively located at the left and right ends, so that when the rotating plates 12 rotate, the opening and closing door 11 is opened from the middle, and two driving motors 13 are provided to drive the two rotating plates 12 to rotate. The housings of the two driving motors 13 are fixed on the sliding part 10, and the ends of their output shafts are respectively fixedly connected to the rotating shafts of the two rotating plates 12. When viewed from above, the area of ​​the opening and closing door 11 is larger than the area of ​​the seedling tray 16, so that the seedling tray 16 is located within the range of the opening and closing door 11 after being pushed onto the sliding part 10.

[0025] The working process of the utility model is briefly described below:

[0026] S1. After the seedling tray 16 is transported to the tail end of the conveyor belt 3, it will be pushed to the opening and closing door 11 on the sliding portion 10 under the thrust of the conveyor belt 3;

[0027] S2. Driven by the vertical drive member and the linear drive member, it can be brought to the stacked position;

[0028] S3. The opening and closing door 11 is opened downward more smoothly, so that the seedling tray 16 located in the middle position slowly slides onto the stacked seedling tray 16;

[0029] S4. Driven by the vertical drive member and the linear drive member, the sliding portion 10 returns to the receiving tray position, and the opening and closing door 11 is closed, waiting for the next seedling tray 16.
