[0021] First, put the straw fragments into the tank body, and then spray the solution. The straw fragments in the tank body are located on the top of the receiving plate. Then start the driving motor, which drives the rotating shaft to rotate, and the rotating shaft drives multiple cams to rotate synchronously. During the contact between the convex end of the cam and the bottom of the receiving plate, the receiving plate is pushed upward. After the convex end of the cam moves out from the bottom of the receiving plate, the receiving plate falls due to gravity. Repeating the above-mentioned vibration operation on the receiving plate for many times can drive the straw fragments to vibrate up and down in the tank body, thereby turning over the straw fragments at different depths, making it convenient for the solution to fully contact the straw fragments.

[0022] A plurality of movable rods 11 are slidably connected to the fixed circular ring 10 , and the upper ends of the movable rods 11 are fixedly connected to the receiving plate 5 , and the lower ends of the movable rods 11 are located below the fixed circular ring 10 and fixedly connected to a stopper 12 .

[0023] An elastic member 9 is disposed between the fixed circular ring member 10 and the receiving plate 5 and sleeved on the circumferential outer wall of the movable rod 11;

[0024] During the vibration of the receiving plate, the receiving plate compresses the elastic part on the surface of the movable rod. The stopper is used to limit the moving stroke of the movable rod to prevent the movable rod from detaching from the fixed circular ring part, thereby improving the stability of the movable rod when moving on the fixed circular ring part, thereby improving the vibration stability of the receiving plate.

[0025] A support plate 8 is located between two adjacent movable rods 11 and is installed on the fixed circular ring 10 .

[0033] A support plate 8 is located between two adjacent movable rods 11 and is installed on the fixed circular ring 10 .

[0034] The support plate 8 below the rotating shaft 6 is provided with a avoiding groove 13 .

[0035] The cams 7 are spaced apart along the length direction of the rotating shaft 6; the directions of the plurality of cams 7 are shifted in sequence, so that the receiving plate can be shaken multiple times, which is beneficial to increase the shaking times of the receiving plate and shake off the straw fragments.
