[0030] A milling assembly with a secondary positioning function comprises a frame 1, a sleeve 2 is mounted on the frame 1, a motor is mounted at the bottom of the frame 1, a milling roller 7 and a screen column 8 are mounted inside the sleeve 2, a positioning mechanism 5 is mounted at the rear end of the milling roller 7, a hopper 4 is mounted on the sleeve 2, a discharge port 3 is mounted at the front end of the sleeve 2, and a pressing and clamping mechanism 6 is mounted at the bottom of the positioning mechanism 5;

[0031] The positioning mechanism 5 consists of two shells 501, two connecting blocks 502, two arc-shaped connecting blocks 503, two arc-shaped clamping blocks 506, several springs 505 and four clamping blocks 504. A hydraulic rod is installed inside the shell 501, and a connecting block 502 is installed at the piston end of the hydraulic rod. The connecting block 502 is connected to the arc-shaped connecting block 503. The right end of the arc-shaped connecting block 503 is provided with several holes for clamping the spring 505. The arc-shaped clamping block 506 is connected to the right end of the arc-shaped connecting block 503 through the spring 505, and the spring 505 is located between the arc-shaped clamping block 506 and the arc-shaped connecting block 503. The clamping blocks 504 are symmetrically installed at the front and rear ends of the connecting block 502.

[0032] In this example, a cylinder is provided between the connecting block 502 and the arc-shaped connecting block 503, the left end of the cylinder is fixedly connected to the right end of the connecting block 502, the right end of the cylinder is fixedly connected to the left end of the arc-shaped connecting block 503, and the cylinder is located at the center position of the connecting block 502 and the arc-shaped connecting block 503.

[0033] It should be noted that the cylinder located between the connecting block 502 and the arc-shaped connecting block 503 not only ensures a stable connection between the two, but also provides an intermediate medium so that the two components can move in coordination.

[0034] In this example, the clamping block 504 is composed of an arc-shaped step 50401 and two step shafts 50402. The step shafts 50402 are symmetrically fixed on the upper and lower parts of the right end face of the arc-shaped step 50401. The connecting block 502 and the arc-shaped connecting block 503 are provided with through holes that cooperate with the step shafts 50402, and the left end face of the arc-shaped step 50401 is in contact with the right end face of the arc-shaped connecting block 503.

[0035] It should be noted that the step shaft 50402 is precisely installed on the arc-shaped step 50401, ensuring the stability of the structure. The through holes provided on the arc-shaped connecting block 503 and the connecting block 502 make the connection between the clamping block 504 and the two tighter and more reliable.

[0036] In this example, the pressing and snap-fitting mechanism 6 consists of an N-shaped base plate and two snap-fitting plates 602. The N-shaped base plate 601 is installed on the top of the rear end of the frame 1, and the snap-fitting plate 602 is installed on the bottom of the shell 501. Both sides of the N-shaped base plate 601 are provided with sliding grooves that cooperate with the snap-fitting plates 602.

[0037] It should be noted that such a position design enables the pressing and clamping mechanism 6 to be stably supported and operated. This design enables the pressing and clamping mechanism 6 to achieve flexible movement and precise control while maintaining stability.

[0038] In this example, the clamping plate 602 is composed of a second shell 60201, a second spring 60203, a square plate 60204 and a clamping column 60202. The clamping column 60202 is in an I-shape. A through hole matching the clamping column 60202 is provided inside the second shell 60201. The second spring 60203 is installed in the groove part of the clamping column 60202. The square plate 60204 is installed at the bottom of the clamping column 60202, and a through groove matching the square plate 60204 is provided at the bottom of the second shell 60201.

[0039] It should be noted that the shape of the clamping column 60202 not only ensures the stability of the mechanism, but also improves the firmness of the connection. The spring installed in the groove enables the clamping column 60202 to produce appropriate elastic deformation when subjected to external force, thereby improving the flexibility and reliability of the clamping.

[0040] In this example, the roller 7 is installed inside the screen column 8, and the rear end of the roller 7 is clamped by a bearing and a pulley, and the pulley cooperates with the motor at the bottom of the frame 1 through a belt.

[0041] It should be noted that this design not only saves space and improves the compactness of the equipment, but also enables the roller 7 to be effectively connected to the motor, thereby achieving efficient transmission and utilization of power.

[0042] To summarize, when installing the rice milling assembly, first attach the roller 7 to the bearing, then place the bearing into the positioning mechanism 5. By simultaneously controlling the inward movement of the hydraulic rods on both sides, the hydraulic rods drive the curved connecting block 503 inward via the connecting block 502, thereby locking the bearing and preventing radial movement of the roller 7. Simultaneously, the inward movement of the curved connecting block 503 also drives the clamping block 504, causing the curved steps 50401 on the clamping block 504 to perfectly lock the front and rear ends of the bearing within, preventing axial movement of the roller 7. To process different materials, the pressing and locking mechanism 6 is simply pressed downward. The clamping post 60202 in the clamping plate 602, under pressure, presses the spring inward, withdrawing from the clamping slot and sliding downward along the groove. When it reaches the predetermined groove position, the spring ejects the clamping post 60202 and pushes it back into its fixed position within the groove. If the whitening assembly needs to be moved upward, the square plates 60204 at the bottom of the two clamping plates 602 are squeezed inward at the same time. The square plates 60204 drive the clamping columns 60202 to move inward, thereby achieving the ascent of the assembly.

[0043] Beneficial effects:

[0044] This grinding assembly with a secondary positioning function ensures that it cannot move radially or axially during the processing process through the design of the positioning mechanism, thereby greatly improving the processing accuracy of the grinding assembly. This dual positioning effectively ensures the stability of the material during the grinding process and greatly improves the processing quality; through the design of the pressing and clamping mechanism, the operator is allowed to flexibly adjust and move the grinding roller according to the characteristics of different materials.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
