[0029] like Figure 1-Figure 6As shown, the processing member 30 is located above the collecting member 20 and contacts the lower end surface of the conveyor belt 11. A water spray hole 302 is provided on the processing member 30. The water spray hole 302 is connected to the external water supply device and the bottom of the collecting member 20 through pipelines. The lower end of the conveyor belt 11 is provided with a scraper 2 14, a cleaning member 15 and a water return member 16. The scraper 2 14 and the water return member 16 are respectively fixedly connected to the base frame 10, and the cleaning member 15 is rotatably connected to the base frame 10, and is connected to the driving member 13 through a transmission belt 3 53.

[0030] In this embodiment, there are two processing members 30, and the end of the processing member 30 facing the conveyor belt 11 has four pointed ends 301. A slide plate 32 for installing the processing member 30 is slidably provided on the base frame 10 along the width direction of the conveyor belt 11. The slide plate 32 is connected to the base frame 10 through an elastic member 321. The elastic member 321 is specifically a first spring.

[0032] The cleaning member 15 has a sponge on its periphery, and the water return member 16 has an extrusion surface 161 on the side facing the cleaning member 15. The water return member 16 has a water storage chamber 162 inside. A through hole 163 connected to the water storage chamber 162 is provided on the extrusion surface 161. The water storage chamber 162 is connected to the bottom of the collecting member 20 through a pipeline. When the cleaning member 15 rotates, the cleaning member 15 can rotate and wipe the surface of the conveyor belt 11 dry, and then the distance between the outer periphery of the cleaning member 15 and the extrusion surface 161 gradually decreases, so that the water on the cleaning member 15 enters the water storage chamber 162 through the through hole 163, and then the water flows back to the collecting member 20.

[0033] like Figure 1 as well as Figure 6-Figure 8As shown, the conveying start end of the conveyor belt 11 is rotatably provided with a shaft cylinder 40, a motor 2 62 for driving the shaft cylinder 40 to rotate is installed on the base frame 10, a guide member 42 fixedly connected to the base frame 10 is provided in the shaft cylinder 40, a plurality of stirring members are evenly spaced on the outer periphery of the shaft cylinder 40, and a mounting hole 401 for installing the stirring member is opened on the shaft cylinder 40. When the shaft cylinder 40 rotates, the stirring member can slide along the radial direction of the shaft cylinder 40, and the stirring member includes a rod 1 43 and a rod 2 44, and the rod 1 43 is rotatably connected to the rod 2 44 through an elastic member 2, and the elastic member 2 is specifically a second torsion spring, and the rod 2 44 is located at the shaft One end of the tube 40 stops at the outer periphery of the guide member 42 and is connected to the shaft tube 40 through an elastic member 441, which is specifically a third spring. The outer periphery of the guide member 42 has a guide surface 421 and a guide surface 422, and the guide surface 422 faces the upper end surface of the conveyor belt 11. A scraper 45 for cleaning rice adhered to the stirring member is provided on the base frame 10 for sliding in the vertical direction. The scraper 45 is connected to the base frame 10 through an elastic member 451, which is specifically a fourth spring. A notch 452 corresponding to the rod 43 is provided at the lower end of the scraper 45.

[0034] In the process of the conveyor belt 11 rotating counterclockwise (viewed from front to back along the axial direction of the shaft cylinder 40) and the shaft cylinder 40 rotating clockwise (viewed from front to back along the axial direction of the shaft cylinder 40), when the rod 2 44 stops against the guide surface 2 422, the connection between the rod 1 43 and the rod 2 44 is located in the mounting hole 401. At this time, the rod 1 43 and the rod 2 44 are in a coaxial state, and as the shaft cylinder 40 rotates clockwise, the rod 1 43 can stir and disperse the rice on the conveyor belt 11; when the rod 2 44 stops against the guide surface 1 421, the elastic member 3 441 is compressed, and the connection between the rod 1 43 and the rod 2 44 is detached from the mounting hole 401. As the shaft cylinder 40 rotates clockwise, the elastic member 3 441 is compressed, and the connection between the rod 1 43 and the rod 2 44 is detached from the mounting hole 401. Rotating clockwise, rod 1 43 can stop with scraper 45 and contact with notch 452. During this process, rod 1 43 can rotate relative to rod 2 44, scraper 45 can move upward, elastic member 451 is gradually compressed, and notch 452 can gradually scrape off rice adhered to rod 1 43. When rod 1 43 and scraper 45 are separated from the stop, scraper 45 can quickly move downward to the extreme position under the action of elastic member 451, and make itself vibrate, thereby shaking off the rice adhered to notch 452 onto conveyor belt 11, thereby facilitating scraper 45 to clean the rice adhered to subsequent rod 1 43.

[0035] Specific working principle: Reference Figure 1-Figure 8, start the motor 1 61 to rotate the conveyor belt 11 counterclockwise (from front to back along the axial direction of the shaft cylinder 40), start the motor 2 62 to rotate the shaft cylinder 40 clockwise (from front to back along the axial direction of the shaft cylinder 40), and pour the cooked rice to the conveying starting end of the conveyor belt 11. Then the rod 1 43 can stir and disperse the rice on the conveyor belt 11, and the scraper 45 can clean the rod 1 43 and the rice adhered to itself. When the cooked rice moves to the conveying end of the conveyor belt 11 and falls from the scraper 12, the rice adhered to the conveyor belt 11 will be partially scraped off by the scraper 12, and the remaining rice will adhere to the surface of the conveyor belt 11 and form a rice mucosa. Then the processing unit 30 can reciprocate along the width direction of the conveyor belt 11 to pass The tip 301 scratches the rice mucus membrane adhered to the surface of the conveyor belt 11, and the water spray hole 302 can spray the water in the collecting member 20 to the position where the processing member 30 scratches, so that the rice mucus membrane can be more fully in contact with the water, which is convenient for the rice mucus membrane to fall off. Then the scraper 2 14 can scrape the rice mucus membrane processed by the processing member 30 onto the filter screen 22 of the collecting member 20, and the water therein can fall into the bottom of the collecting member 20 through the filter screen 22. Then the cleaning member 15 rotates and wipes the surface of the conveyor belt 11 to facilitate the subsequent transportation of rice. Then, the outer periphery of the cleaning member 15 is squeezed with the extrusion surface 161, so that the water on the cleaning member 15 enters the water storage chamber 162 through the through hole 163, and then the water flows back to the collecting member 20 to reuse the water.

A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
