Then start the electric telescopic rod 505, which pushes the entire adjustable fixing mechanism 3 to move forward. The adjustable fixing mechanism 3 drives the circular block 604 and the sliding block through the rectangular frame 701. When the sliding block 605 moves forward along the convex groove 606, when the sliding block 605 moves completely into the U-shaped groove 1 607, under the action of gravity, the entire adjustable fixing mechanism 3 automatically turns counterclockwise by 90 degrees and continues to slide downward along the U-shaped groove 2 608 until the circular block 604 and the sliding block 605 slide together to the bottom of the U-shaped groove 2 608, and then the electric hydraulic cylinder 901 is started, and the electric hydraulic cylinder 901 drives the rectangular box 902 to move upward until the tray 705 moves completely into the rectangular box 902, and then the electric hydraulic cylinder 901 is started. Motor 2 904, Motor 2 904 drives active snap ring 905 to rotate, active snap ring 905 drives driven snap ring 906 to rotate through a transmission belt, driven snap ring 906 rotates rotating column 907, rotating column 907 drives bevel gear 1 908 and capstan 1001 to rotate together, bevel gear 1 908 drives bevel gear 2 1103 to rotate, bevel gear 2 1103 drives screw rod 3 1102 to rotate, screw rod 3 1102 drives extrusion plate 1104 to move upward, so that extrusion plate 1104 pushes cleaning fluid to the hose 1105, the cleaning liquid is then transmitted to the cleaning nozzle 1003 through the hose 1105, so that the cleaning liquid is sprayed out from the cleaning nozzle 1003, thereby cleaning the tray 705. At the same time, the capstan 1001 drives the connecting block 1004 to move upward along the fixed column 1002, and the connecting block 1004 drives the cleaning nozzle 1003 to move upward, so that the cleaning nozzle 1003 moves upward while spraying the cleaning liquid, thereby achieving comprehensive cleaning of the tray 705. After the cleaning is completed, the tray 705 can be reset as described above.
