[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0026] Example:

[0027] Please refer to Figure 1-4The embodiment of the present application provides an automated seedling tray stacking structure, which includes a conveyor frame 1 and a stacking mechanism. The conveyor frame 1 is provided with a conveyor belt 2; the stacking mechanism includes two lifting plates 3 respectively arranged on both sides of the conveyor belt 2, and the bottoms of the two lifting plates 3 are fixedly connected with a lifting frame 4, which is arranged below the conveyor belt 2, and the bottom of the lifting frame 4 is provided with a lifting device 5; a through slot 6 is provided on the lifting plate 3, and the side of the lifting plate 3 away from the conveyor belt 2 is rotatably connected to a horizontal rotating rod 7; a support member 8 is fixedly provided on the horizontal rotating rod 7, and one end of the support member 8 passes through the through slot 6 and is above the conveyor belt 2.

[0028] The existing stacking device generally has a complex structure, is prone to malfunction, has low stacking efficiency, cannot fully meet different stacking requirements, and has a narrow application range. The utility model realizes the raising and lowering of the lifting plate 3 connected to the lifting frame 4 through the lifting device 5. During the lowering process of the lifting plate 3, the support member 8 is blocked by the edge of the seedling tray 15 on the conveyor belt 2, driving the horizontal rotating rod 7 to rotate so that the support member 8 can be moved below the seedling tray 15; during the rising process of the lifting plate 3, the support member 8 is supported by the bottom limit of the through groove 6, so that the seedling tray 15 can be lifted by the edge of the seedling tray 15; the lifting process of the entire device is fast and simple, and a plurality of seedling trays 15 can be stacked by rotating the support member 8 and moving the lifting plate 3 up and down. The stacking efficiency is high, the adaptability is strong, the failure rate is low, and it is easy to maintain.

[0029] Specifically, when the seedling tray 15 moves between the two lifting plates 3 along with the conveyor belt 2, the lifting device 5 drives the lifting frame 4 to move downward. The support member 8, which descends along with the lifting plate 3, rotates and moves to the bottom of the seedling tray 15 via the horizontal rotating rod 7. After that, it rotates due to gravity and is located at the bottom edge of the seedling tray 15. The lifting device 5 drives the lifting frame 4 to rise, and the support member 8 lifts the seedling tray 15 under the bottom limit of the through groove 6. Through the repeated operation of the lifting device 5, multiple seedling trays 15 can be quickly stacked. It is understandable that the lifting device 5 can be set as a common lifting device 5 on the market, such as an electric telescopic rod or a pneumatic telescopic rod.

[0030] Furthermore, in the present invention, a ring sleeve 16 is provided on the lifting plate 3 , and the horizontal rotating rod 7 is rotatably sleeved with the ring sleeve 16 .

[0031] Furthermore, in the present invention, two stacking mechanisms are provided, and a controller 9 is provided on the conveyor frame 1, which is connected to the conveyor belt 2 and the lifting device 5. Providing two stacking mechanisms can greatly increase stacking efficiency, allowing two stacking operations to be performed during a single movement of the conveyor belt 2. The controller 9 is connected to the conveyor belt 2 and the lifting device 5, allowing an operator to control the coordinated operation of the conveyor belt 2 and the lifting device 5 through the controller 9. It is understood that the controller 9 can be a PLC controller.

[0032] Furthermore, in the present invention, the support member 8 is configured in a downwardly curved arc shape, with the top surface of the support member 8 being horizontal. The downwardly curved arc shape of the support member 8 allows it to easily rotate under the obstruction of the edge of the seedling tray 15 and thus move below the seedling tray 15; the support member 8 with a horizontal top surface facilitates the lifting of the seedling tray 15. It is understood that the shape of the through groove 6 is configured such that when the bottom end of the support member 8 abuts the through groove 6, the top surface of the support member 8 is horizontal; the height of the top of the through groove 6 is configured such that the support member 8 can be fully or partially rotated into the through groove 6, allowing the seedling tray 15 to move above it after the support member 8 rotates.

[0033] Furthermore, in the present invention, a clamping piece 10 is provided on the side of the lifting plate 3 facing the conveyor belt 2. The side of the clamping piece 10, which is closer to the conveyor belt 2 in the direction of the incoming material, is connected to the lifting plate 3, and the other side of the clamping piece 10 is tilted inward. The provision of the clamping piece 10 allows it to better stabilize the seedling trays 15 during stacking, preventing them from tilting and turning.

[0034] Please refer to Figure 4 Furthermore, in the present invention, the clamping piece 10 is hingedly connected to the lifting plate 3. A return spring 11 is provided on the side of the clamping piece 10 away from the lifting plate 3. One end of the return spring 11 is fixedly connected to the clamping piece 10, and the other end is fixedly connected to the lifting plate 3. The return spring 11 can make the clamping piece 10 abut against the seedling tray 15, thereby increasing stability. It is understood that the spring rate and length of the return spring 11 are adjusted to stabilize the seedling tray 15 and enable the seedling tray 15 to move under the drive of the conveyor belt 2.

[0035] Furthermore, in the present invention, an auxiliary conveyor belt 12 is provided between the two lifting plates 3. Due to the provision of the clamping piece 10, the resistance of the seedling raising tray 15 between the two lifting plates 3 is relatively large. The provision of the auxiliary conveyor belt 12 can provide a good moving force for the seedling raising tray 15 after it is stacked, thereby preventing it from getting stuck between the two lifting plates 3.

[0036] Furthermore, in the present invention, a vertical cylinder 13 is provided on the side of the lifting plate 3, and a fixed pulley 14 is provided on the conveyor frame 1. The vertical cylinder 13 and the fixed pulley 14 are adapted in shape and slidably connected. The coordinated arrangement of the vertical cylinder 13 and the fixed pulley 14 makes the lifting plate 3 more stable during the upward and downward movement.

[0037] To sum up, an embodiment of the present invention provides an automated seedling tray stacking structure, which includes a conveyor frame 1 and a stacking mechanism, and a conveyor belt 2 is provided on the conveyor frame 1; the stacking mechanism includes two lifting plates 3 respectively arranged on both sides of the conveyor belt 2, and the bottoms of the two lifting plates 3 are fixedly connected with a lifting frame 4, and the bottom of the lifting frame 4 is provided with a lifting device 5; a through slot 6 is provided on the lifting plate 3, and a horizontal rotating rod 7 is provided on the side of the lifting plate 3 away from the conveyor belt 2 through a ring sleeve 16 for rotation and sleeve connection; a support member 8 is fixedly provided on the horizontal rotating rod 7, one end of which passes through the through slot 6 and is above the conveyor belt 2. The utility model realizes the rising and falling of the lifting plate 3 connected to the lifting frame 4 through the lifting device 5. During the descending process of the lifting plate 3, the support member 8 is blocked by the edge of the seedling tray 15 on the conveyor belt 2, driving the horizontal rotating rod 7 to rotate so that the support member 8 can be moved to the bottom of the seedling tray 15; during the rising process of the lifting plate 3, the support member 8 is supported by the bottom limit of the through groove 6, so that the seedling tray 15 can be lifted through the edge of the seedling tray 15; the lifting process of the entire device is fast and simple, and a plurality of seedling trays 15 can be stacked by rotating the support member 8 and moving the lifting plate 3 up and down, which has high stacking efficiency, strong adaptability, low failure rate and is easy to maintain.
