[0031] Please refer to the attached drawing, which is a structural schematic diagram of a preferred embodiment of an agricultural product grinding device provided by the utility model.

[0032] An agricultural product grinding device, comprising:

[0033] The grinding assembly includes a feed hopper 5, a first grinding chamber 6 connected to the bottom opening of the feed hopper 5 in sequence, a connecting cylinder 7, a second grinding chamber 8 and a discharge channel 21, a first grinding roller assembly 13 is arranged in the first grinding chamber 6, the first grinding roller assembly 13 is used to perform a primary grinding of the agricultural product fed from the feed hopper 5 to form a primary grinding product, the connecting cylinder 7 is used to transport the primary grinding product to the second grinding chamber 8, a second grinding roller assembly 15 is arranged in the second grinding chamber 8, the second grinding roller assembly 15 is used to perform a secondary grinding of the primary grinding product to form a secondary grinding product and discharge the secondary grinding product to the discharge channel 21;

[0034] A spraying assembly, the spraying assembly is used to spray the agricultural products fed from the feed hopper 5;

[0035] The discharge filter assembly 9 is connected to the discharge channel 21 and is used for filtering the secondary grinding products in the discharge channel 21 .

[0036] The "installation cylinder 24" herein means a structure connected to the discharge channel 21 for installing the filter screen cylinder assembly. In one embodiment, the installation cylinder 24 is configured as a full cylindrical structure, and the inner wall of the installation cylinder 24 can provide all-round shielding and protection for the filter screen cylinder assembly, thereby achieving a better shielding effect.

[0037] In another embodiment, the mounting cylinder 24 can also be set as a semicircular groove structure. In this case, a protective cover 28 is installed above the mounting cylinder 24 to shield and protect the filter cylinder assembly. A split structure is adopted between the protective cover 28 and the mounting cylinder 24, which is more convenient for disassembly, cleaning, repair and maintenance.

[0038] When the installation cylinder 24 is a transverse semicircular groove structure, installation platforms are provided on the tops of both sides of the installation cylinder 24. The installation platforms are used to support the filter screen cylinder assembly and the protective cover 28. The installation cylinder 24 can be supported and fixed by a bracket.

[0039] In some embodiments, a fine mesh is provided in the second grinding chamber 8, and the fine mesh is used to receive the material to be ground for the second time. Only the material that reaches the specified fineness can be discharged, and the coarser material continues to be ground by the second grinding assembly 15, and is discharged from the fine mesh after the fineness reaches the standard, thereby effectively improving the extraction rate of starch in the material. The utility model realizes the secondary grinding of agricultural product raw materials through the first grinding chamber 6 and the second grinding chamber 8 connected in sequence from top to bottom, so as to achieve more sufficient grinding. Among them, the first grinding chamber 6 is provided with a first grinding roller assembly 13 to grind the material fed by the feed hopper 5 once, and the material that has been ground once enters the second grinding chamber 8 and is ground for the second time by the second grinding roller assembly 15, which effectively improves the degree of grinding and crushing. The material that has been ground for the second time enters the discharge filter assembly 9, and the discharge filter assembly 9 is provided with a filter screen cylinder assembly and a stirring mechanism, which can realize that the material is pushed and stirred while discharging and filtering, so that the fineness of the filtered slurry is better and there are fewer particles.

[0040] Preferably, please refer to Figure 3 As shown, the first grinding roller assembly 13 includes a first grinding roller and a second motor 3 connected to the first grinding roller and used to drive the first grinding roller to rotate. The outer wall of the first grinding roller is provided with a plurality of spurs in an annular array.

[0041] It is understandable that the outer wall of the first grinding roller is provided with thorns to crush and grind the agricultural product material fed from the feed hopper 5, thereby achieving primary grinding of the agricultural product material. Preferably, the thorns can adopt a conical structure, which can reduce excessive residual material on the thorns and facilitate the cleaning of the first grinding roller.

[0042] Preferably, please refer to Figure 6 As shown, the second grinding roller assembly 15 includes a second rotating shaft 19, a first motor 2 for driving the second rotating shaft 19, a mounting shaft 18 and a grinding blade 16. The mounting shaft 18 is arranged parallel to the second rotating shaft 19. The mounting shaft 18 is provided with a plurality of roots and arranged in a circumferential annular array along the second rotating shaft 19 on the outer ring of the second rotating shaft 19. A plurality of grinding blades 16 are arranged on the mounting shaft 18. The second rotating shaft 19 is used to drive the mounting shaft 18 to rotate along the axis of the second rotating shaft 19.

[0043] It can be understood that the grinding blade 16 can rotate around the installation shaft 18. The second rotating shaft 19 drives the installation shaft 18 to rotate while also driving the grinding blade 16 to rotate. Multiple grinding blades 16 can improve the grinding and crushing effect of agricultural product materials and effectively improve the degree of crushing.

[0044] In some embodiments, the second rotating shaft 19 is provided with a separation plate 20 arranged in an axial direction, the separation plate 20 is provided with a ring array of mounting holes, the mounting shaft 18 is passed through the mounting holes, and the separation plate 20 is used to separate the arranged grinding blades 16 into multiple sections. The separation plate 20 can strengthen the fixing of the mounting shaft 18.

[0045] Optionally, the side wall of the grinding blade 16 is a tooth surface structure, and two limiting through holes 17 are symmetrically opened on the grinding blade 16 along the center line of the grinding blade 16 . The grinding blade 16 is sleeved on the mounting shaft 18 through one of the limiting through holes 17 .

[0046] It is understandable that the tooth surface structure of the side wall of the grinding blade 16 can improve the crushing ability of the grinding blade 16. The two limiting through holes 17 on the grinding blade 16 can both play a role in installation. When the grinding blade 16 is installed using the first limiting through hole 17, the first side of the grinding blade 16 is facing the rotation direction of the second rotating shaft 19, so it is in contact with the material for a longer time and will be more easily worn out after long-term use. At this time, the second limiting through hole 17 can be replaced for installation, so that the second side of the grinding blade 16 faces the rotation direction of the second rotating shaft 19, and the second side with a lower degree of wear is used to continue the crushing and grinding operation. Therefore, the provision of two limiting through holes 17 can effectively increase the service life of the grinding blade 16, make fuller use of wearing parts, and reduce replacement costs.

[0047] Preferably, please refer to Figure 1 , 2 As shown, the spray assembly includes a water inlet pipe 4, the first end of the water inlet pipe 4 extends into the feed hopper 5, and a section of the water inlet pipe 4 located in the feed hopper 5 is provided with a spray section, the spray section of the water inlet pipe 4 is provided with a plurality of spray outlets, and the second end of the water inlet pipe 4 is located outside the feed hopper 5 and is used to connect to a water source.

[0048] It is understandable that the spray section of the water inlet pipe 4 can spray water into the feed hopper 5 to mix the clean water with the ground agricultural product material to form a slurry, which is then convenient for subsequent filtering operations.

[0049] Preferably, please refer to Figure 3 and 7 As shown, the filter screen cylinder assembly includes a first arc-shaped filter plate 22, a second arc-shaped filter plate 27 and a support plate assembly. The second arc-shaped filter plate 27 and the first arc-shaped filter plate 22 are connected and enclosed to form a filter channel. The second arc-shaped filter plate 27 and the first arc-shaped filter plate 22 are both made of metal materials. The support plate assembly is used to support the first arc-shaped filter plate 22 and the second arc-shaped filter plate 27 respectively.

[0050] It is understandable that the second curved filter plate 27 and the first curved filter plate 22 are connected vertically, which can facilitate the disassembly, cleaning and replacement of the filter cylinder assembly, and also facilitate the disassembly and step-by-step installation of the support plate assembly. In addition, the vertical splicing structure of the second curved filter plate 27 and the first curved filter plate 22 can also facilitate the replacement of the stirring member 23 and greatly reduce the difficulty of cleaning the filter cylinder assembly.

[0051] It should be noted that the existing equipment mostly uses filter screen cylinders made of cloth nets. Although the cost is lower and it is easy to replace, the cloth nets are easily damaged, which affects the processing efficiency, and the mesh holes of the cloth nets are difficult to make fine, which affects the quality of filtration, making it easy for the final product to have too many particles, affecting the quality of the finished product. Therefore, the present application uses stainless steel to make the first curved filter plate 22 and the second curved filter plate 27, which can achieve finer and less prone to damage filter mesh holes, and strengthen the position fixing of the first curved filter plate 22 and the second curved filter plate 27 through the support plate assembly, thereby improving the stability and service life of the filter screen cylinder assembly.

[0052] Preferably, please refer to Figure 3 As shown, the support plate assembly includes a first support plate 26 and a second support plate, the first support plate 26 is used to abut and support the outer wall of the second curved filter plate 27, and the second support plate is used to abut and support the outer wall of the first curved filter plate 22. It can be understood that the first support plate 26 and the second support plate can abut and provide support with the first curved filter plate 22 and the second curved filter plate 27 in a one-to-one correspondence. Preferably, the first curved filter plate 22 and the second curved filter plate 27 are semi-cylindrical structures, and the first support plate 26 and the second support plate are curved plate structures, so that the first support plate 26 and the second support plate can be arranged in a one-to-one correspondence with the first curved filter plate 22 and the second curved filter plate 27, providing a more stable support.

[0053] In some embodiments, a plurality of first support plates 26 are provided, the plurality of first support plates 26 are arranged in an array, and the distance between the plurality of first support plates 26 gradually increases along the feeding direction of the filter mesh drum assembly; a plurality of second support plates are provided, the plurality of second support plates are arranged in an array, and the distance between the plurality of second support plates gradually increases along the feeding direction of the filter mesh drum assembly.

[0054] It can be understood that the first end of the mounting cylinder 24 is connected to the discharge port 14 of the discharge channel 21, where the material flow is the largest, and therefore the impact force on the filter screen cylinder assembly is also the largest. Therefore, the first support plate 26 and the second support plate in this section have a higher density and more support points, which can provide a more stable support and ensure the stability of the filter screen cylinder assembly.

[0055] Preferably, please refer to Figure 3 As shown, the stirring mechanism includes a first rotating shaft 10, a third motor 12 connected to the first rotating shaft 10 and used to drive the first rotating shaft 10 to rotate, and a stirring member 23 arranged on the first rotating shaft 10. The first end of the first rotating shaft 10 is arranged in the discharge channel 21 and is rotatably connected to the side wall of the discharge channel 21. The second end of the first rotating shaft 10 is passed through the filter screen drum assembly and extends along the length direction of the filter screen drum assembly. A spiral blade is arranged on a section of the first rotating shaft 10 located in the discharge channel 21. The section of the first rotating shaft 10 located in the filter screen drum assembly is a hollow structure and a plurality of spray outlet holes are opened on the outer wall. The stirring member 23 is provided in multiple and annular arrays along the circumference of the first rotating shaft 10 on a section of the first rotating shaft 10 located in the filter screen drum assembly.

[0056] It is understandable that the spiral blades can push the material into the filter screen cylinder assembly, and the stirring member 23 can continue to push the material to move along the length direction of the filter screen cylinder assembly while stirring the material to improve the filtering effect.

[0057] It should be noted that the second end of the first rotating shaft 10 is connected to a water source to realize a water spraying operation at the hollow section of the first rotating shaft 10, thereby improving the filtering effect of the material in the filter cylinder assembly.

[0058] Optionally, the stirring member 23 includes a stirring plate, on which a brush is arranged, and the stirring plate is arranged at an angle to the axis of the first rotating shaft 10 .

[0059] It is understandable that the brush on the stirring plate can abut against the filter screen cylinder assembly to clean the inner wall of the filter screen cylinder assembly while stirring the slurry material, thereby reducing the residue on the filter screen cylinder assembly, speeding up the filtration discharge speed, and improving the filtration effect. The stirring plate is tilted, which can provide a certain effect of pushing the material forward when rotating.

[0060] It should be noted that the entire grinding assembly can be installed through the mounting frame 1, wherein the first motor 2, the second motor 3 and the third motor 12 can be fixed on the mounting frame 1 through a motor bracket.

[0061] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0062] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. The above is only the preferred implementation method of the utility model.
