Technical Field

[0001] The utility model relates to the technical field of raw material processing equipment, in particular to a raw material sorting and crushing device. Background Art

[0002] Spices are a type of natural plant products with typical flavors such as aroma and spiciness. They generally refer to small granular seasonings made from aromatic plants, such as dried plant seeds, fruits, roots, bark, etc., which are crushed by a crusher and are mainly used in food seasoning and flavoring. At present, in the process of producing and using spices, spices are mostly processed and used in the form of fine powder. Therefore, in the process of producing and processing spices, it is necessary to crush the different materials that make up the spice materials into crushed materials, and then perform micro-crushing again after crushing.

[0040] It can be understood that when the feed slider 41 rises, the push rod 45 pushes against the connecting ring 32 to push the box body 31 up. When the box body 31 rises to a preset position, the push rod 35 pushes against the top of the flip rod 15. In the subsequent process of the connecting ring 32 continuing to rise, the box body 31 is limited by the flip rod 15 and tilted toward the hopper 13, and the spices that have not been completely crushed in the box body 31 are poured into the hopper 12 and crushed again by the crushing structure 20. When the tilting is completed, the feed motor 44 is driven to move the feed slider 41 downward, and the box body 31 is also tilted toward the hopper 13 under the action of gravity. The feed slider 41 moves downward, and during the downward movement, the push rod 35 disengages from the flip rod 15. Under the gravity of the counterweight block 34, the box body 31 automatically returns to the center until the first limit plate 36 abuts against the second limit plate 37, preventing the box body 31 from continuing to flip and keeping the box body 31 flat. After returning to the initial position, the connecting ring 32 is rotated to make the box body 31 return to the bottom of the hopper 13 for sorting again. It should be noted that the push rod 45 abuts against the connecting ring 32, and the boss 38 abuts against the bottom of the first slot 141 or the second slot 142, so that the box body 31 will not slide off automatically.

[0041] When in use, the spices are poured from the notch 11 into the hopper 13, and the crushing structure 20 squeezes and crushes them. The crushed spices fall into the box 31, and the filter 50 filters and sorts the spices. The crushed spices fall from the filter 50 into the collection box 60 for collection, and the spices that are not completely crushed remain on the filter 50. After the crushing is completed, the box 31 is manually rotated to stagger it with the hopper 13. , then start the feed motor 44 to rotate forward, drive the box 31 to rise until the top rod 35 abuts against the top of the flip rod 15, so that the box 31 is dumped toward the hopper 13, and the spices that are not completely crushed are poured back into the crushing structure 20 for re-crushing; after pouring, drive the drive motor 44 to reverse, so that the box 31 moves down to the initial position, and then manually rotate the box 31 again to make it return to the bottom of the hopper 13, and sort the spices again. Through the cooperation between the lifting structure and the sorting box, the automatic sorting and filtering of spices and the secondary crushing of spices are realized, and the crushing effect can be improved while sorting, reducing manpower consumption.
