Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a polishing drum structure for rice processing. Background Technique

[0002] Rice is the finished product made after processes such as cleaning, hulling, milling, and finished product finishing of paddy. After the paddy is dehulled, it becomes brown rice. After the brown rice removes most of the cortex and a part of the embryo, it becomes rice. There is still a small amount of bran powder on the surface of the rice grains, which affects the appearance quality, storability of the rice, and the taste of the cooked rice. Therefore, this part of bran powder needs to be removed through the polishing process.

[0003] After retrieval, the publication number is (CN217663484U), which discloses a polishing drum structure for rice processing, including a box body and a polishing drum. The inner top wall of the box body is communicated with two feed hoppers. The inner top wall of the box body is fixedly installed with guide plates located on the opposite sides of the two feed hoppers. The inner top wall of the box body is provided with a polishing component located between the two feed hoppers. A driving component connected to the polishing component is arranged inside the box body. A screening component sleeved outside the driving component is arranged inside the box body. A vibration component attached to the screening component is arranged inside the box body. The vibration component is connected to the driving component. Adjusting components are arranged on the left and right sides of the inner wall of the box body. The polishing drum is arranged between the two adjusting components.

[0004] When implementing this technical solution, at least the following defects still exist: Although this utility model can polish rice, it is inconvenient to carry out intermittent feeding during the feeding process, resulting in a large amount of rice accumulation, which will affect the polishing and screening effects, and further affect the processing quality of rice. Urgent improvement is needed. Therefore, we propose a polishing drum structure for rice processing. Content of the Utility Model

[0027] A winding drum 22 is fixedly installed at the rear end of the transmission rod 21. A traction rope 23 is wound around the outer side wall of the winding drum 22. A baffle 25 is movably installed at the upper end of the support frame 1. A fixed frame 4 is movably installed at the lower end of the support frame 1. The other end of the fixed frame 4 is detachably connected to the collection box 14 by bolts. A second spring 5 is sleeved on the outer side wall of the fixed frame 4. The other end of the traction rope 23 bypasses the guide wheel and is fixedly connected to the lower end of the baffle 25. Facilitated by the arrangement of the traction rope 23, the baffle 25 can be tractionally moved. The output end of the rotary motor 11 is equipped with a polishing roller, and the polishing roller is arranged in the polishing cylinder 12. Through openings are provided at both the upper and lower ends of the polishing cylinder 12, which facilitates ensuring the polishing and discharging of rice. A screen 15 is detachably installed at the upper end of the collection box 14, and the size of the screen 15 is the same as the size of the upper opening of the collection box 14, which facilitates screening the falling rice.

[0028] A first spring 24 is fixedly installed on one side of the lower end of the baffle 25, and the other end of the first spring 24 is fixedly connected to the support frame 1. Facilitated by the arrangement of the first spring 24, the baffle 25 can be driven to reset.

[0029] A cam rod 3 is fixedly installed at the front end of the transmission rod 21, and the cam rod 3 is arranged between the fixed frame 4 and the support frame 1. Facilitated by the arrangement of the cam rod 3, the fixed frame 4 can be continuously pushed.

[0030] During processing, first, rice is discharged into the polishing cylinder 12 through the discharge pipeline 13. At the same time, the rotary motor 11 is turned on. The rotary motor 11 drives the polishing roller to rotate at a high speed in the polishing cylinder 12, so as to polish the passing rice. At the same time, the servo motor 2 is turned on. The servo motor 2 drives the transmission rod 21 to rotate periodically forward and backward, so that the transmission rod 21 intermittently drives the winding drum 22 to rotate, so that the winding drum 22 continuously winds or releases the traction rope 23. Combined with the resilience of the first spring 24, the baffle 25 is driven to move intermittently back and forth left and right, and then intermittently block or open the lower part of the discharge pipeline 13, and then intermittently feed the rice, thus avoiding the situation that a large amount of rice accumulates and affects the polishing effect. At the same time, during the rotation of the transmission rod 21, the cam rod 3 on the transmission rod 21 will continuously push the fixed frame 4, and combined with the second spring 5, the collection box 14 can be driven to shake back and forth on the support frame 1, thereby improving the screening efficiency of the collection box 14. And through the arrangement of the balls on the support frame 1, the smoothness of the contact between the collection box 14 and the support frame 1 is ensured, thereby facilitating driving the collection box 14 to move left and right.
