[0020] See also Figure 1-3The utility model provides a rice crushing device for agricultural product processing, comprising a crushing box 1, a filter screen 2 arranged obliquely is fixed between the inner walls of both sides of the crushing box 1, a crushing mechanism is arranged above the filter screen 2, the crushing mechanism comprises crushing rollers 3 arranged above the filter screen 2 and symmetrically distributed, both ends of the crushing rollers 3 are rotatably connected to the inner wall of the crushing box 1, and the rotation directions of the two crushing rollers 3 are arranged in opposite directions, a symmetrically distributed rotating motor 4 is fixed to the outer wall of the crushing box 1, the output shaft of the rotating motor 4 is fixed to the side wall of the crushing roller 3, and a discharge port 6 and a feed port 6 are provided on the outer wall of the crushing box 1. The outlet 6 is connected to the lower end of the filter screen 2, and an inclined feed plate 7 is fixed to the bottom end of the feed port 5. The other end of the feed plate 7 is located in the middle of the two crushing rollers 3, which can be used to circulate and crush the raw materials that do not meet the specifications. A recovery platform 8 is slidably connected to the outer wall of one side of the crushing box 1. A baffle 11 is fixed to the bottom side wall of the recovery platform 8. A recovery groove 9 is opened on the side wall of the recovery platform 8 close to the crushing box 1. The recovery groove 9 has a first state and a second state. In the first state, the recovery groove 9 is connected to the inside of the outlet 6, and in the second state, the recovery groove 9 is connected to the feed port 5. At this time, the baffle 11 closes and protects the discharge port 6, and a discharge plate 10 with an inclined surface is fixed to the bottom end of the recovery tank 9. In the second state, the raw materials on the surface of the discharge plate 10 enter the feed port 5 along the inclined surface of the discharge plate 10, forming a circulating feeding process. A driven shaft 15 is fixed to the side wall of one of the crushing rollers 3 away from the rotating motor 4, and the other end of the driven shaft 15 is located outside the crushing box 1, and an incomplete gear 16 is fixed to the other end of the driven shaft 15. A circulation plate 12 is fixed to the upper surface of the recovery table 8, and a circulation channel 13 running through the front and back is opened on the circulation plate 12. Circulation racks 14 are provided on both side walls of the annular channel 13 along its length direction, and an incomplete gear 16 is located inside the circulation channel 13. The incomplete gear 16 is meshed and drivenly connected with the circulation rack 14, so that during the rotation and crushing of the crushing roller 3, the non-conforming raw materials can be automatically driven to be circulated and crushed. A collecting box 18 is placed on the bottom surface of the crushing box 1, and the collecting box 18 is located directly below the filter screen 2. A discharge channel 17 is provided on the outer wall of the crushing box 1, so that the collecting box 18 can be moved in and out of the discharge channel 17 to collect and process the crushed raw materials.

[0021] This scheme has the following working process: when the rice is crushed, the rice is poured between the two crushing rollers 3, and the two rotating motors 4 are started. The rotating motor 4 drives the crushing rollers 3 to rotate, so that the two crushing rollers 3 rotate in opposite directions, and the rice is crushed. The completely crushed rice passes through the filter screen 2 and falls into the collecting box 18 for collection. The rice raw materials that do not meet the specifications enter the recovery tank 9 from the discharge port 6 along the inclination angle of the filter screen 2. At this time, the crushing roller 3 drives the driven shaft 15 to rotate, and the driven shaft 15 drives the incomplete gear 16 to rotate. The meshing transmission between the incomplete gear 16 and the circulating rack 14 drives the circulation plate 12 to move up and down in a circular motion. The circulation plate 12 drives the recovery platform 8 to move up and down in a circular motion. During the upward movement, the recovery tank 9 is connected with the feed port 5, and during the downward movement, the recovery tank 9 is connected with the discharge port 6, so that the raw materials inside the recovery tank 9 fall from the feed port 5 into the feed plate 7, and finally fall back between the two crushing rollers 3 for re-crushing.
