DETAILED DESCRIPTION

[0022] The following will be described in detail in combination with the accompanying Figures 1-4 The application will be further described in detail.

[0023] The embodiment of the application discloses a grinding device for agricultural product processing and production. Figures 1-4 A grinding device for agricultural product processing and production, comprising a grinding cylinder 1, a crushing assembly and a grinding assembly are arranged in the grinding cylinder 1, a first motor 3 for driving the crushing assembly to rotate is arranged at the top of the grinding cylinder 1, a second motor 16 for driving the grinding assembly is arranged at the bottom of the grinding cylinder 1, the first motor 3 and the second motor 16 are independently driven, the rotating speed of the first motor 3 is greater than that of the second motor 16, and a screen 8 is rotatably arranged between the crushing assembly and the grinding assembly.

[0024] By adopting the above technical scheme, the motor one 3 is arranged at the top of the grinding cylinder 1, and the motor two 16 is arranged at the bottom of the grinding cylinder 1, so that the dust pollution problem caused by arranging the motor in the grinding chamber is avoided. The motor one 3 and the motor two 16 are arranged at the top and the bottom of the grinding cylinder 1 respectively, away from the grinding area, which is convenient for daily cleaning and maintenance. At the same time, the space at the top and the bottom of the grinding cylinder 1 is effectively utilized, and the space occupied by the motor one 3 and the motor two 16 in the grinding cylinder 1 is reduced. The motor one 3 and the motor two 16 are independently driven, and the rotating speed of the motor one 3 is greater than that of the motor two 16. The crushing assembly and the grinding assembly can be optimized and controlled respectively, so that the crushing and grinding stages can be more matched with the respective process requirements, thereby ensuring the stability of the equipment operation. The screen 8 can effectively screen out particles that do not meet the requirements, thereby improving the quality and consistency of the final product.

[0025] With reference to Figure 1 , 2 , the crushing assembly includes a crushing shaft 4, a crushing mortar 5 and crushing leaves 6. The crushing mortar 5 is fixed in the grinding cylinder 1, the crushing shaft 4 rotates in the grinding cylinder 1, and the crushing leaves 6 are provided in two groups. Each group of crushing leaves 6 is composed of three vertically staggered blades of different lengths. The two groups of crushing leaves 6 are located in the crushing mortar 5 and are fixed on the surface of the crushing shaft 4 at intervals. A discharging port 7 is formed in the bottom of the crushing mortar 5, and the rotor end of the motor one 3 is fixed with the crushing shaft 4.

[0026] It should be noted that the crushing leaves 6 are composed of three vertically staggered blades of different lengths. In the crushing process, the agricultural products can be cut and torn at multiple angles and multiple levels, thereby improving the crushing efficiency. At the same time, the blades of different lengths can better cover the crushing range, ensuring that the agricultural products are fully crushed.

[0027] By adopting the above technical scheme, the motor one 3 is started to drive the crushing shaft 4 and the crushing leaves 6 thereon to rotate, so as to crush the agricultural products in the crushing mortar 5. The crushed agricultural products fall through the discharging port 7 and are screened on the screen 8.

[0028] With reference to Figure 1 , 3 , the grinding assembly includes a grinding block 9, a scraper 10 and a grinding shaft 15. The inner wall bottom of the grinding cylinder 1 is arc-shaped, the grinding shaft 15 rotates at the inner wall bottom of the grinding cylinder 1, the grinding block 9 is fixed on the grinding shaft 15, the bottom of the grinding block 9 is arc-shaped and has a gap with the bottom of the grinding cylinder 1, the scraper 10 is fixed on one side of the grinding block 9, the side of the scraper 10 away from the grinding block 9 is attached to the inner wall of the grinding cylinder 1, the rotor end of the motor two 16 is fixed with the grinding shaft 15, and the screen 8 is fixed at one end of the grinding shaft 15 away from the grinding block 9.

[0029] By adopting the above technical solution, starting motor 16 causes grinding shaft 15 to drive grinding block 9 and screen 8 to rotate. As grinding block 9 rotates, it further grinds the agricultural products screened from screen 8. The arc-shaped fit between the bottom of grinding block 9 and the inner wall of grinding cylinder 1 can reduce the clogging of agricultural products and play an effective grinding role, improving the fineness of the produced agricultural products. Scraper 10 rotates with grinding block 9 to scrape the bottom of grinding cylinder 1, preventing agricultural products from adhering to the inner wall of grinding cylinder 1 and thus affecting the grinding effect. Screen 8 rotates with grinding block 9, which can increase the sieving frequency of screen 8, improve sieving efficiency, and at the same time prevent screen 8 from clogging.

[0030] Reference Figure 1 , 3 The screen 8 is conical, and the grinding cylinder 1 has a slag discharge port 13. The edge of the screen 8 is tangent to the bottom of the outer diameter of the slag discharge port 13. The outer wall of the grinding cylinder 1 is provided with a slag discharge pipe 14 corresponding to the slag discharge port 13.

[0031] By adopting the above technical solution, the slag discharge port 13 is tangent to the edge of the screen 8, which can ensure that large particles or impurities that do not pass through the screen 8 can slide along the conical inclined surface of the screen 8 to the slag discharge port 13 and be discharged through the slag discharge pipe 14 for further crushing.

[0032] Reference Figure 1 The top of the grinding cylinder 1 is provided with a feed pipe 2, which is bent.

[0033] By adopting the above technical solution, the agricultural products to be ground are added from the feed pipe 2. The bent design can increase the flow path of the agricultural products before entering the grinding cylinder 1, so that the agricultural products can enter the grinding area more smoothly and reduce the risk of blockage caused by straight falling.

[0034] Reference Figure 1 The bottom of the grinding cylinder 1 is provided with a discharge pipe 12, and a filter plate 11 is provided at the bottom of the grinding cylinder 1 corresponding to the discharge pipe 12;

[0035] By adopting the above technical solution, agricultural products must pass through the filter plate 11 after grinding to ensure that the agricultural products are fully mixed and ground in the grinding cylinder 1, thereby improving the grinding efficiency. At the same time, it can ensure that only the fine powder that has been fully ground is discharged through the discharge pipe 12, while the coarse particles that do not meet the grinding requirements will be intercepted by the filter plate 11 and returned to the grinding area for further grinding, thereby improving the purity of the product.

[0036] The implementation principle of the grinding device for agricultural product processing and production is that: the agricultural products to be ground are put into the crushing mill 5 from the feeding pipe 2, and the motor one 3 is started to make the crushing blade 6 crush the agricultural products, the crushed powder falls into the screen 8 through the discharging port 7, the motor two 16 is started to drive the screen 8, the fine grinding block 9 and the scraper 10 to rotate, the powder screened from the screen 8 is further ground by the fine grinding block 9 and then discharged from the discharge pipe 12, and the particles not screened are discharged from the slag discharge pipe 14 and then put into the feeding pipe 2 again for crushing, and the cooperation of the motor one 3 and the motor two 16 at the top and the bottom of the grinding cylinder 1 not only improves the grinding efficiency but also is convenient for maintenance.

[0037] Finally, it should be pointed out that: first, in the description of the present application, it should be pointed out that unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, which can be mechanical connection or electrical connection, or the communication between two elements, or direct connection, "up", "down", "left", "right" and the like are only used to indicate the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may change;
