[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides the following technical solution: a rapid automatic rice seedling tray placement machine, including a working plate 1, a working box 2 fixedly installed on the inner side of the working plate 1, a first motor 18 fixedly installed on one side of the surface of the working box 2, a first rotating shaft 13 provided at the output end of the first motor 18, a second limiting plate 14 fixedly installed on the surface of the first rotating shaft 13, a second motor fixedly installed on the other side of the surface of the working plate 1, a second rotating shaft 16 provided at the output end of the second motor, a first limiting plate 10 fixedly installed on the surface of the second rotating shaft 16, a first electric push rod 19 fixedly installed on both sides of the working plate 1, a first connecting plate 3 provided at the output end of the first electric push rod 19, a clamping plate 15 fixedly installed on the inner side of the first connecting plate 3, a second electric push rod 20 fixedly installed at the bottom of the working plate 1, a connecting frame 8 provided at the output end of the second electric push rod 20, a second connecting plate 6 fixedly installed at the bottom of the connecting frame 8, and a second connecting hole 12 opened on the surface of the second connecting plate 6.

[0021] In a specific embodiment of this utility model, an external screw is used to pass through the second connecting hole 12 to fix the device to the rice seedling tray. The second electric push rod 20 is operated to retract, causing the connecting frame 8 to slide inside the working plate 1, adjusting the height between the working plate 1 and the rice seedling tray. The operator places the plastic tray into the working box 2. The first electric push rod 19 is operated to extend and retract, moving the first connecting plate 3 and the clamping plate 15 to move, limiting the bottom of the plastic tray to the second limiting plate 14 and the first limiting plate 10. The clamping plate 15 then limits the second-to-last plastic tray. The first motor 18 and the second motor are operated to rotate the first rotating shaft 13 and the second rotating shaft 16, causing the second limiting plate 14 and the first limiting plate 10 to rotate, dropping the plastic tray into the rice seedling tray. This process is repeated to automatically feed the plastic tray, reducing manual tray placement and lowering labor intensity.

[0022] In this embodiment: the operator holds the connecting block 5 to lift it, so that the box door 4 moves upward to open, and places the plastic trays into the inside of the work box 2 to form a stacked state. Conversely, after releasing the connecting block 5, the box door 4 moves downward to close. The operation is simple and reduces the difficulty of using this equipment.

[0023] In this embodiment: the operator pulls the third connecting plate 9 to pull the limiting rod 11 out of the inside of the connecting frame 8. When the connecting frame 8 moves to a suitable position inside the working plate 1, the operator releases the third connecting plate 9. Through the elastic force generated by the reset spring 17, the limiting rod 11 moves into the first connecting hole 7 on the surface of the connecting frame 8 to limit the position and improve the stability of the equipment.

[0024] The working principle and usage process of this utility model are as follows: After the utility model is installed, external screws are used to pass through the second connecting hole 12 to fix the device to the rice seedling tray. The operator holds the connecting block 5 and lifts it to move the box door 4 upward and open it, placing the plastic trays inside the working box 2 to form a stacked state. Conversely, after releasing the connecting block 5, the box door 4 moves downward and closes. The operator pulls the third connecting plate 9 to pull the limiting rod 11 out of the connecting frame 8. The second electric push rod 20 is activated, causing the push rod of the second electric push rod 20 to retract, sliding the connecting frame 8 inside the working plate 1 to adjust the height between the working plate 1 and the rice seedling tray. When the connecting frame 8 moves to the appropriate position inside the working plate 1, the operator releases the third connecting plate 9. The elastic force generated by the return spring 17 moves the limiting rod 11 into the first connecting hole 7 on the surface of the connecting frame 8 for limiting. The first electric push rod 19 is activated. The device operates by retracting the first electric push rod 19, moving the first connecting plate 3 and the clamping plate 15 away from the bottom of the plastic tray, and limiting the bottom of the plastic tray to the surface of the second limiting plate 14 and the first limiting plate 10. Then, the first electric push rod 19 extends, moving the first connecting plate 3 and the clamping plate 15 to the bottom of the second-to-last plastic tray for further limitation. The second motor then rotates the second rotating shaft 16, causing the first limiting plate 10 to rotate, dropping one end of the plastic tray into the rice seedling tray. The first motor 18 then rotates the first rotating shaft 13, causing the second limiting plate 14 to rotate, dropping the other end of the plastic tray into the rice seedling tray. This process is repeated to automatically feed the plastic trays, reducing manual tray placement. All electrical equipment in this device is powered by an external power source, and the motors and electric push rods are controlled by a PLC controller system.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
