[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5A food screening device for easy discharging includes a box body 1, an upper screen 5 and a lower screen 6 are arranged inside the box body 1, a feed port is arranged on the upper end surface of the box body 1, and discharge ports 3 are arranged on the outer walls on both sides and the front of the box body 1, a feed hopper 2 is installed on the feed port, a collecting trough 4 is installed on the discharge port 3, a vertical rod 7 is installed between the upper screen 5 and the lower screen 6, a cavity 8 is arranged inside the vertical rod 7, a driving motor 9 is arranged in the cavity 8, two impact rods 11 are arranged in the cavity 8 through a reset mechanism, the impact rod 11 is connected to the driving motor 9 through a rotating mechanism, and an impact channel 15 connected with the cavity 8 and matched with the impact rod 11 is provided on the vertical rod 7.

[0023] The reset mechanism includes a connecting plate 13 installed on the impact rod 11, and a reset spring 14 is provided in the cavity 8. The two ends of the reset spring 14 are elastically connected to the outer wall of the connecting plate 13 and the inner wall of the cavity 8 respectively. The reset spring 14 can drive the impact rod 11 to reset after it moves and loses its restraining force, and use the end of the impact rod 11 to impact the upper screen 5 and the lower screen 6.

[0024] The rotating mechanism includes a rotating gear 10 installed on the output shaft of the driving motor 9, and a rack 12 is provided on the impact rod 11 to cooperate with the rotating gear 10. The rotating gear 10 is an incomplete gear. Since it is an incomplete gear, when the part without teeth corresponds to the rack 12, the rotating gear 10 will contact and mesh with the rack 12.

[0025] The upper screen 5 and the lower screen 6 are both inclined, and the mesh of the upper screen 5 is smaller than that of the lower screen 6. Therefore, the top collection slot 4 will collect the smallest food material, the middle collection slot 4 will collect the largest food material, and the bottom collection slot 4 can collect medium-sized food material.

[0026] The inner bottom wall of the discharge port 3 is inclined, and the inner bottom wall of the box body 1 is inclined. The above-mentioned inclined arrangement facilitates the food material to pass through and enter the corresponding collecting trough 4, ensuring the smoothness of the material when sliding down.

[0027] The cross-sectional view of the vertical rod 7 is circular, and the outer wall of the vertical rod 7 is polished, and the polishing process ensures smoothness, thereby preventing the vertical rod 7 from obstructing the material sliding down the lower screen 6.

[0028] When the utility model is used, the food material to be screened enters the box body 1 through the feed port and the feed hopper 2, slides through the upper screen 5 to the lower screen 6, and finally slides through the lower screen 6 to the middle collecting trough 4. During this process, the top collecting trough 4 will collect the food material with the smallest volume, the middle collecting trough 4 will collect the food material with the largest volume, and the bottom collecting trough 4 can collect food material with a medium volume.

[0029] Part of the food material will be in the mesh holes of the upper screen 5 and the lower screen 6 and will be blocked and will not fall down. At this time, it is necessary to start the driving motor 9 to drive the rotating gear 10 to rotate. When the rotating gear 10 rotates, the part with teeth engages with the rack 12. As the driving motor 9 and the rotating gear 10 continue to rotate, the rack 12 drives the impact rod 11 to move, and the two impact rods 11 move closer (the impact rod 11 is never separated from the impact channel 15). Therefore, the matching connecting plate 13 will drag the reset spring 14. As the driving motor 9 and the rotating gear 10 continue to rotate, the part without teeth on the rotating gear 10 will correspond to the rack 12. At this time, the rack 12 loses its restraining force. Under the action of the reset spring 14, the impact rod 11 moves and resets and hits the upper screen 5 and the lower screen 6. The vibration generated by the impact can shake out the material in the mesh, thereby realizing automatic cleaning and maintenance.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
