Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] The present invention provides an automatic trimming system based on a seedbed as shown in Figure 1 、 Figure 5 , which includes a servo motor 1, a sliding table 2, a photoelectric switch 3, a PLC 4, a proximity switch 5, a servo drive 6, a disclosure 7, a switching power supply 8, a control box 9, and an encoder 10; the servo motor 1 is installed on the sliding table 2 through a sheet metal part, and the proximity switch 5 is installed on the outside of the sliding table 2 through screws, as shown in Figure 4 , the servo drive 6, the disclosure 7, the switching power supply 8, and the PLC 4 are installed in the control box 9 through drilling and tapping, as shown in Figure 2 , the proximity switch 5 is installed on the seedbed through a sheet metal part, the encoder 10 is installed on the seedbed through a sheet metal part, and the photoelectric switch 3 is installed on the seedbed through a sheet metal part.

[0032] Inside the control box 9, the servo drive 6, the switching power supply 8, the PLC 4, and the disclosure 7 are physically installed, as shown in Figure 3 , the servo drive 6, the switching power supply 8, and the PLC 4 are connected by wires, and the proximity switch 5 and the PLC 4 are connected by wires;

[0033] The servo drive 6 is connected to the PLC 4 by wires, and the servo motor 1 and the servo drive 6 are connected to the outside through a guide rail by wires;

[0034] The diffuse reflection photoelectric switch 3 is connected to the PLC 4 by wires; the encoder 10 is connected to the PLC 4 by wires;

[0035] In order to realize the stable operation of the stepping sliding table 2, the servo drive 6 cooperates with the PLC 4 to accurately control the movement of the servo motor 1 to a specified position through pulses; at the same time, proximity switches 5 are added on both sides of the sliding table 2 to prevent the risks brought by the movement of the motor and play a role in avoiding risks.

[0036] In order to realize the precise positioning of each tray of lawn, the encoder 10 is physically installed on the seedling tray gear, powered by the switching power supply 8, and the pulse signal is connected to the PLC 4. The moving distance of the seedling tray is calculated through pulses to improve the trimming accuracy.

[0037] To achieve the stability of the construction of seedling trays, a photoelectric switch 3 is added and physically installed on the seedling bed. Each time a seedling tray comes, it will trigger the photoelectric switch 3 to accurately fix the starting position of trimming, ensuring the neatness and aesthetics of each tray of trimming.

[0038] Working principle: The PLC 4 sends pulse commands to the servo drive 6. The servo drive 6 drives the servo motor 1 through the coding wire, and the servo motor 1 drives the slide table 2 to move for trimming operations. For safety and stability, proximity switches 5, photoelectric switches 3, and encoders 10 are respectively installed on the seedling rack. The moving distance and digital quantity of the seedling tray are calculated through pulses for precise positioning. For the power supply, we select a switching power supply 8 for voltage conversion processing. The control is integrated in the control box 9 to prevent interference from external factors and ensure long-term stable operation.

[0039] This automatic trimming system based on the seedling bed realizes automatic trimming of the seedling bed, solves the technical problems of the agricultural trimming that is inseparable from manual operation and the time and labor costs, and realizes the function of automatic trimming without manual intervention through the combination of PLC digital management and servo motor, vacuum cleaner, encoder, and sensor. It can automatically trim to keep the lawn neat and beautiful and meet the user's needs. The system can automatically trim, realizing a trimming system without manual intervention. The automatic trimming system can reduce the labor force and run automatically when powered on. The trimming effect will be more neat. In some corners that are difficult to trim manually, the slide table can carry scissors, playing a more convenient, fast, labor-saving, and stable function in the agricultural system.
