[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-4As shown, this utility model provides a technical solution: a food raw material crushing device, including a cylinder 1, an inner cylinder 2 installed inside the cylinder 1, and a crushing cylinder structure 3 installed inside the inner cylinder 2. The crushing cylinder structure 3 includes a crushing cylinder 31, a rotating shaft 32, a plurality of crushing blades 33, and a motor 34. The plurality of crushing blades 33 are arranged on the rotating shaft 32, and the plurality of crushing blades 33 and the rotating shaft 32 are arranged inside the crushing cylinder 31. The top side of the rotating shaft 32 is connected to the cylinder 1 through a bearing, and the rotating shaft 32 is driven by the motor 34. The outer side of the middle part of the crushing cylinder 31 is installed inside the inner cylinder 2 through a connecting column. The top side of the crushing cylinder 31 is connected to the inner side of a connecting plate 16, and the outer side of the connecting plate 16 is connected to the top edge of the inner cylinder 2. The bottom of the crushing cylinder 31 is conical, with the inner cylinder 2 being lower than the outer cylinder 1. The bottom of the crushing cylinder 31 has a central discharge port corresponding to the central top of the screen 7. An annular channel 4 is formed between the inner cylinder 2 and the cylinder 1, and an annular collection box 5 is installed inside the annular channel 4. The inner wall of the bottom of the collection box 5 is inclined. When the material is conveyed upward through the collection box 5, it can slide onto the connecting plate 16 using the inclined surface. Food raw materials are added through the feeding hopper 19 and enter the top of the crushing cylinder 31 through the discharge pipe 18. Driven by the motor 34, the rotating shaft 32 and the crushing blades 33 rotate, crushing the falling food raw materials. The crushed materials then slide down through the central discharge port at the bottom of the crushing cylinder 31 to the central top of the screen 7. The conical screen 7 can then screen out small particles. The material falls downwards, allowing larger particles to slide down the inclined surface. Food ingredients not pulverized to small particle size will slide down the inclined surface of the screen 7 and enter the collection box 5 through the discharge chute 8. The collection box 5 has linkage plates 11 on both sides, which are connected to the vertical sliding grooves 12 on the side walls of the cylinder 1. The collection box 5 rises or falls within the annular channel 4 via a screw drive structure. The screw drive structure includes an arc-shaped rod 13, a screw 14, and a forward / reverse motor 15. The two ends of the arc-shaped rod 13 are connected to the two linkage plates 11, and the screw 14 is connected to the threaded cylinder in the middle of the arc-shaped rod 13. The top side of the screw 14 is connected to the output shaft of the forward / reverse motor 15. Both the screw 14 and the forward / reverse motor 15 are installed on the outside of the cylinder 1, and the forward / reverse motor 15 drives the screw. Rotating screw 14 causes the arc-shaped rod 13 to rise or fall via a threaded cylinder, raising or lowering the linkage plates 14 at both ends of the arc-shaped rod 13 within the vertical slide groove 12. This, in turn, causes the collection box 5 to rise or fall within the annular channel 4. The inner wall of the collection box 5 has an opening 6, and a conical screen 7 is installed on the bottom side of the inner cylinder 2. Driven by the screw drive structure, the collection box 5 rises within the annular channel 4, and the electric push rod 10 simultaneously pushes the sealing plate 9 down to temporarily seal the discharge chute 8, preventing large particles from falling down. When the collection box 5 rises to the top of the annular channel 4, and the opening of the collection box 5 aligns with the upper surface of the connecting plate 16, the collected food raw materials fall into the crushing cylinder structure 3 for secondary crushing, achieving automated secondary crushing of large food raw materials.Then, driven by the screw drive structure, the collecting box 5 descends within the annular channel 4, and the sealing plate 9 rises to open the discharge chute 8, allowing the collecting box 5 to continue collecting large particles of food material. The side slope of the conical screen 7 is greater than 45 degrees, which ensures the smooth descent of the material. The bottom side wall of the inner cylinder 2 has a discharge chute 8, and the bottom inner wall of the inner cylinder 2 is equipped with an annular sealing plate 9. The sealing plate 9 is driven by two electric push rods 10. The electric push rods 10 push the sealing plate 9 down to temporarily seal the discharge chute 8, preventing large particles of material from falling down. During normal crushing operation of the crushing cylinder structure 3, large particles of material requiring secondary crushing can be blocked at the lowest side of the screen 7. When the collecting box 5 descends and resets, the sealing plate 9 rises, at which point the accumulated large particles of material will be released. The material slides into the collection box 5, allowing the crushing device to operate without stopping while the collection box 5 conveys large particles upwards. An annular connecting plate 16 is provided on the top side of the inner cylinder 2 and the crushing cylinder structure 3. Two feeding hoppers 19 are provided on the top side of the cylinder 1, and a discharge pipe 18 is provided on the bottom side of the feeding hoppers 19. The discharge pipe 18 connects to and passes through the top side wall of the cylinder 1, and the bottom side of the discharge pipe 18 corresponds to the crushing cylinder structure 3. A cover 17 is provided on the top side of the crushing cylinder 31. The rotating shaft 32 passes through the central hole of the cover 17, and the cover 17 is connected to the discharge pipe 18. The cover 17 prevents material from flying upwards out of the crushing cylinder 31 when food raw materials are crushed inside the crushing cylinder structure 3, and the edge of the cover 17 does not contact the connecting plate 16, thus not obstructing the normal downward sliding of material on the connecting plate 16.

[0023] The operation steps of this utility model are as follows:

[0024] Food ingredients are added through the feeding hopper 19 and enter the top of the crushing cylinder 31 through the feeding pipe 18. Driven by the motor 34, the rotating shaft 32 and the crushing blades 33 rotate, crushing the falling food ingredients. The crushed ingredients then slide down through the feeding port at the bottom center of the crushing cylinder 31 to the top center of the screen 7. The conical screen 7 can screen out small particles and allow larger particles to slide down the inclined surface. Food ingredients that are not crushed to the point of being small particles will slide down the inclined surface of the screen 7 and enter the collection box 5 through the discharge chute 8 for collection. Driven by the screw drive structure, the collection box... The collection box 5 rises within the annular channel 4, and the electric push rod 10 simultaneously pushes the sealing plate 9 down to temporarily seal the discharge chute 8, preventing large particles from falling down. When the collection box 5 rises to the top side of the annular channel 4, and the opening of the collection box 5 corresponds to the upper surface of the connecting plate 16, the collected food raw materials will fall into the crushing cylinder structure 3 for secondary crushing, realizing automated secondary crushing of large particles of food raw materials. Then, driven by the screw drive structure, the collection box 5 descends within the annular channel 4, and the sealing plate 9 rises to open the discharge chute 8, enabling the collection box 5 to continue collecting large particles of food materials.
