[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0029] Please refer to the attached drawing, which is a structural schematic diagram of a preferred embodiment of a grinding roller mechanism and an agricultural product grinding device provided by the present invention.

[0030] A grinding roller mechanism comprising:

[0031] A feed hopper 5, a first grinding chamber 6, a connecting cylinder 7, and a second grinding chamber 8 connected in sequence to the bottom opening of the feed hopper 5, a discharge port being provided at the bottom end of the second grinding chamber 8, a first grinding roller assembly 13 being provided in the first grinding chamber 6, the first grinding roller assembly 13 being used to perform a primary grinding of the agricultural products fed from the feed hopper 5 to form a primary grinding product, the connecting cylinder 7 being used to convey the primary grinding product to the second grinding chamber 8, a second grinding roller assembly being provided in the second grinding chamber 8, the second grinding roller assembly being 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 port;

[0032] The spraying assembly is used to spray the agricultural products fed from the feed hopper 5.

[0033] The utility model realizes secondary grinding of agricultural raw materials by connecting the first grinding chamber 6 and the second grinding chamber 8 in sequence from top to bottom, achieving more complete grinding. The first grinding chamber 6 is provided with a first grinding roller assembly 13 to grind the material fed from the feed hopper 5 for the first time. The material after the first grinding enters the second grinding chamber 8 and is grinded for the second time by the second grinding roller assembly, effectively improving the degree of grinding and crushing.

[0034] In some embodiments, a fine-pored curved mesh is provided in the second grinding chamber 8, which is used to receive the material to be ground for the second time. Only the material that reaches the specified fineness can be discharged, while the coarser material continues to be ground by the second grinding assembly and is only discharged from the fine-pored curved mesh after the fineness reaches the standard, thereby effectively improving the extraction rate of starch in the material.

[0035] Preferably, please refer to Figure 1 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 14 in an annular array.

[0036] It can be understood that the outer wall of the first grinding roller is provided with thorns to crush and grind the agricultural product materials fed from the feed hopper 5, thereby achieving primary grinding of the agricultural product materials.

[0037] It should be noted that the feed hopper 5 and the first grinding chamber 6, the connecting cylinder 7 and the second grinding chamber 8 can be installed through the mounting frame 1, the second motor 3 can be fixedly mounted on the mounting frame 1 through the motor bracket, the output shaft of the second motor 3 is connected to the second driving pulley 10, and the second driving pulley 10 can be connected to the second driven pulley 12 of the first rotating shaft of the first grinding roller through a belt. Preferably, a double belt is used for connection, so that the machine can still work normally after one of the belts breaks, thereby realizing the error-proofing function.

[0038] Optionally, the spur 14 is a cone structure or a triangular plate structure.

[0039] It is understandable that the spurs may adopt a conical structure or a triangular plate structure, which can reduce excess residual material on the spurs and facilitate cleaning of the first grinding roller.

[0040] In one embodiment, the second grinding roller assembly includes a first rotating shaft 19, a first motor 2 connected to the first rotating shaft 19 and used to drive the first rotating shaft 19 to rotate, and a grinding blade 16, the grinding blade 16 is sleeved on the first rotating shaft 19, and multiple grinding blades 16 are arranged along the axial direction of the first rotating shaft 19.

[0041] It should be noted that the first motor 2 can be fixedly mounted on the mounting frame 1 via a motor bracket. The output shaft of the first motor 2 is connected to a first driving pulley 9, which is connected to a first driven pulley 11 of the first rotating shaft 19 of the second grinding roller via a belt. Preferably, a double belt is used for connection, so that the machine can still operate normally even if one of the belts breaks, thereby realizing a fault-proofing function.

[0042] In another embodiment, the second grinding roller assembly includes a first rotating shaft 19, a first motor 2 connected to the first rotating shaft 19 and used to drive the first rotating shaft 19 to rotate, and a mounting shaft 18 and a grinding blade 16. The mounting shaft 18 is arranged parallel to the first rotating shaft 19. The mounting shaft 18 is provided with multiple shafts and is arranged in a circumferential annular array along the outer ring of the first rotating shaft 19. Multiple grinding blades 16 are arranged on the mounting shaft 18. The first rotating shaft 19 is used to drive the mounting shaft 18 to rotate along the axis of the first rotating shaft 19.

[0043] It can be understood that the grinding blade 16 can rotate around the installation shaft 18. The first 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] Preferably, please refer to Figure 3 As shown, two limiting through holes 17 are symmetrically formed on the grinding blade 16 along the center line of the grinding blade 16 , and the grinding blade 16 is installed through one of the limiting through holes 17 .

[0045] Preferably, the sidewall of the grinding blade 16 is a toothed structure.

[0046] It is understood that the toothed sidewall structure of the grinding blade 16 can enhance the grinding performance of the grinding blade 16. Both stop holes 17 on the grinding blade 16 serve as mounting holes. When the grinding blade 16 is mounted using the first stop hole 17, the first side of the grinding blade 16 faces the direction of rotation of the first rotating shaft 19, resulting in a longer period of contact with the material and increased wear over time. In this case, the second stop hole 17 can be replaced with the second stop hole 17, allowing the second side of the grinding blade 16 to face the direction of rotation of the first rotating shaft 19, allowing the grinding operation to continue using the second side, which is less susceptible to wear. Therefore, the provision of two stop holes 17 effectively increases the service life of the grinding blade 16, allowing for more efficient utilization of wearing parts and reducing replacement costs.

[0047] Preferably, please refer to Figure 3 As shown, a plurality of separation plates 20 are arranged and sleeved on the first rotating shaft 19 along the axial direction. A plurality of mounting through holes are formed in an annular array on the separation plates 20 , and the mounting through holes are used to pass through and fix the mounting shaft 18 .

[0048] As will be appreciated, a plurality of separator plates 20 are arranged axially along the first rotating shaft 19. The separator plates 20 have mounting holes formed in an annular array, through which the mounting shaft 18 passes. The separator plates 20 are used to separate the arranged grinding blades 16 into multiple sections. The separator plates 20 reinforce and secure the mounting shaft 18.

[0049] Preferably, please refer to Figure 1 、 2 As shown, the spray assembly includes a water adding pipe 4, the first end of the water adding pipe 4 extends into the feed hopper 5, and a section of the water adding pipe 4 located in the feed hopper 5 is provided with a spray section, and the spray section of the water adding pipe 4 is provided with a plurality of spray outlets. The second end of the water adding pipe 4 is located outside the feed hopper 5 and is used to connect to a water source.

[0050] It is understandable that the spray section of the water supply 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.

[0051] According to another aspect of the present invention, an agricultural product grinding device is provided, which includes the above-mentioned grinding roller mechanism.

[0052] The agricultural product grinding device of the present invention also has the aforementioned beneficial effects. It comprises a first grinding chamber 6 and a second grinding chamber 8, which are connected in sequence from top to bottom, enabling secondary grinding of agricultural raw materials, achieving more complete grinding. A first grinding roller assembly 13 is located within the first grinding chamber 6, which performs a primary grinding of the material fed from the feed hopper 5. The primary grinding of the material then enters the second grinding chamber 8, where it is then subjected to a secondary grinding by the second grinding roller assembly, effectively increasing the degree of grinding and comminution.

[0054] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. The above is only a preferred implementation method of the present invention. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures.
