The gear 914 is provided on the side wall of the rotating rod and the side wall of the output shaft of the driving motor 913. The cross-section of the material-picking plate 964 is arc-shaped, which is convenient for taking and collecting the residual materials on the transmission belt 10. In addition, when the shortest distance between the top of the material-picking plate 964 and the axis of the rotating drum 961 is greater than the height difference between the axis of the rotating drum 961 and the conveyor belt 10, the top of the material-picking plate 964 will be subjected to thrust when it rotates to contact the conveyor belt 10, the elastic member 963 will be compressed, and the material-picking plate 964 will shrink into the receiving groove 962, and its inner arc surface will dig out the accumulated residual materials.

[0046] Furthermore, the push member includes a connecting rod 1 911 and a connecting rod 2 99 arranged on the side wall of the connecting rod 1 911 , a sealing plate 912 is arranged on the side wall of the connecting rod 2 99 , a through slot 97 is opened on the side wall of the water tank 93 , and the connecting rod 2 99 passes through the through slot 97 .

[0048] In this embodiment, there are two placement areas 916, which are respectively opened on both sides of the cleaning box 91. The scrapers 92, elastic members 963, and push members are all in two groups, which are respectively arranged in the two placement areas 916. The sealing plate 912 is mounted between the two connecting rods 99.

[0049] Furthermore, a blocking bar 12 is provided on the inner wall of the baffle plate 3 , opposite to the scraper 92 .

[0050] Furthermore, a control component 13 is provided on the frame 1, and a signal processing component 14 is provided on the motor 1 4 and the cleaning mechanism 9. The control component is used to control the opening and closing of the motor 1 4, the motor 2 8 and the drive motor 913.

[0051] In this embodiment, the control component 13 includes an input unit, a signal processing unit and a signal output unit, and the processing component 14 includes a signal processing unit and a signal output unit. Both can adopt numerical control equipment in the prior art, which is the prior art and will not be described in detail.

[0052] When the cleaning mechanism cleans, the driving source drives the cleaning assembly 9 to move from one side of the conveyor belt 10 to the other side until the scraper 92 is in close contact with the baffle 12. At this time, the scraper 92 will be subjected to the pressure of the baffle 12, and the elastic member 963 will be compressed under the pressure, and the scraper 92 will move in the box placement area 916, thereby driving the push member to move, so that the sealing plate 912 moves along the sliding groove, so that the originally closed water outlet 98 is opened, and the water in the water tank 93 flows into the water diversion box 94 through the water outlet 98, and finally flows out from the water pipe 95. When the picking plate 964 rotates to the bottom of the water pipe 95, the water flowing out of the water pipe 95 flows into the inner arc surface of the picking plate 964 through the perforation, flushing the residual material collected on the inner arc surface of the picking plate 964, so that the residual material falls into the material receiving area 915 under the flushing force and its own gravity.

[0053] The specific method of using the three-layer fermentation bed for fermenting Pu'er tea is as follows: when the fermentation of Pu'er tea on the fermentation bed is completed, start motor 14 to drive the conveyor belt 10 to move, and transport the tea leaves on the conveyor belt 10 to the next equipment. Then, drive the conveyor belt 10 to move to the position where the tea leaves are fermented. At this time, the tail of the original tea pile is located at the baffle 12, and start the electric telescopic rod 11 to make the bottom of the cleaning component 9 contact with the conveyor belt 10. At this time, the scraper 92 contacts the baffle plate 3, and start motor 2 8 to make the cleaning component 9 move along the length direction of the conveyor belt 10. As the cleaning component 9 moves, the tea leaves adhering to the conveyor belt 10 and the baffle plate 3 will be scraped off and pushed by the cleaning box 91. When the scraper 92 is in close contact with the baffle 12, turn off motor 2 8. At this time, the cleaning box 91 stops. The tea leaves attached to the baffle plate 3 and the conveyor belt 10 are finally collected on the conveyor belt 10 near the baffle bar 12. At this time, the driving motor 913 is started to drive the cleaning member 96 to rotate, and the rotating picking plate 964 will dig out the residual material accumulated on the conveyor belt 10 near the baffle bar 12. Moreover, when the baffle bar 12 is in close contact with the scraper 92, the scraper 92 moves toward the placement area 916, driving the push member to move, thereby driving the sealing plate 912 to move, so that the water outlet trough 98 is opened, and the water in the water tank 93 drips onto the picking plate 964 through the water pipe 95, flushing the residual material on the picking plate 964 into the collecting area 915. After the picking plate 964 picks up materials multiple times, all the residual material is collected in the collecting area 915. After the picking is completed, the cleaning component 9 is moved to its original position.
