Description

Technical Field

[0001] The utility model relates to the technical field of rice milling machines, in particular to an emery roller mechanism of a rice milling machine. Background Art

[0002] The rice milling machine mainly uses the mechanical force generated by mechanical equipment to peel and whiten the brown rice. When the brown rice flows into the whitening chamber from the hopper, the brown rice is squeezed in the whitening chamber due to the internal pressure of the lead and the mechanical force. After self-friction and mutual friction between the brown rice and the emery roller, the cortex of the brown rice can be quickly removed. In the prior art, the structure of the commonly used emery roller rice milling machine is usually that the rice milling emery roller is vertically installed in the machine body, and a whitening space is formed between the rice milling emery roller and the milling drum. When working, the driving shaft is used to drive the emery roller to rotate, and the brown rice material enters the whitening space from the feed hopper above the machine body. The brown rice is fully rubbed and whitened between the brown rice, the milling drum, and the emery roller, so as to achieve separation between rice grains and chaff.

[0003] Based on the above rice milling process, it is concluded that the internal sand rollers and milling drums of the existing rice milling machine are prone to stick to rice and rice husks during use. If they are not cleaned or replaced in time, the sticky rice and rice husks are likely to form a convex structure, resulting in unbalanced force, making the internal sand rollers easy to be damaged, and easily affecting the subsequent rice milling process, resulting in reduced rice milling speed and quality. In view of this, we propose a sand roller mechanism for a rice milling machine. Utility Model Content

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0024] A sand roller mechanism of a rice mill, see Figures 1 to 5 , comprising a sand roller body 1, a detachable component 2 is connected to the top of the sand roller body 1, a cleaning mechanism 3 is sleeved on the surface of the detachable component 2, and a limiting mechanism 4 is arranged inside the cleaning mechanism 3;

[0025] The detachable component 2 includes a fixed rod 201, which is fixedly connected to the top surface of the emery roller body 1, and a threaded rod 202 is fixed on the top of the fixed rod 201. A hollow cylinder 203 is matched and sleeved on the outside of the threaded rod 202. A connecting piece 204 is provided on the top of the hollow cylinder 203, and the connecting piece 204 is connected to the driving motor. The utility model effectively realizes the assembly of the cleaning mechanism 3 and the emery roller body 1 through the detachable component 2. The cleaning mechanism 3 effectively reciprocates up and down to clean the emery roller body 1 and the inner wall of the milling drum, thereby reducing the residue of rice and rice husk on the inner wall of the emery roller body 1 and the milling drum, reducing the damage to the emery roller body 1, and at the same time, the emery roller body 1 and the milling drum after cleaning will not affect the subsequent rice milling rate and quality.

[0026] Specifically, the cleaning mechanism 3 includes a limit plate 301, which is fixedly sleeved on the outside of the hollow cylinder 203, and a group of hydraulic cylinders 302 are fixedly embedded in the limit plate 301. It is worth noting that the hydraulic cylinder 302 in the utility model is a multi-stage hydraulic cylinder, and the movable end of the hydraulic cylinder 302 is connected to a special-shaped rod 303, and the bottom of the special-shaped rod 303 is connected to an annular frame 304. Further, the special-shaped rod 303 is in an inverted Z shape, and the hydraulic cylinder 302 is connected to the annular frame 304 through the special-shaped rod 303. The annular frame 304 is sleeved with a groove frame 305 on the outside, and a plurality of brush clusters 306 are distributed in an annular manner on the surface of the groove frame 305. Further, the plurality of brush clusters 306 distributed on the inner annular surface of the groove frame 305 can fit with the surface of the sand roller body 1. The sand roller body 1 is located in the rolling drum, and the plurality of brush clusters 306 distributed on the outer annular surface of the groove frame 305 can fit with the inner wall of the rolling drum. In the utility model, when the rice milling process is completed, the hydraulic cylinder 302 effectively drives the special-shaped rod 303 and the annular frame 304 to move up and down, thereby realizing the up and down movement of the groove frame 305 and the brush cluster 306. The brush cluster 306 on the inner ring surface of the groove frame 305 effectively cleans the surface of the sand roller body 1, and the brush cluster 306 on the outer ring surface of the groove frame 305 effectively cleans the inner wall of the milling drum, thereby improving the cleaning efficiency.

[0027] It is worth noting that the limiting mechanism 4 includes a limiting rod 401, which is fixedly arranged inside the slot frame 305. Furthermore, the limiting rod 401 runs through the inside of the annular frame 304. The limiting rod 401 is provided with a group, and the surface of the limiting rod 401 is provided with a thread, and the outside of the limiting rod 401 is matched and screwed with a limiting screw ring 402. In the utility model, the annular frame 304 and the slot frame 305 are effectively assembled through the cooperation of the limiting rod 401 and the limiting screw ring 402. When the brush cluster 306 needs to be cleaned or replaced later, the annular frame 304 can be separated from the slot frame 305 by disassembling the limiting screw ring 402, thereby improving convenience.

[0028] Working principle: a set of limiting rods 401 are passed through the annular frame 304 and then screwed to limit the position by the limiting screw ring 402 to realize the assembly between the annular frame 304 and the groove frame 305. Then, the cleaning mechanism 3 and the emery roller body 1 are assembled by screwing the threaded rod 202 and the hollow cylinder 203. Then, the connecting piece 204 is connected to the driving motor. When the driving motor is started, the emery roller body 1 rotates to mill rice. After the rice milling process is completed, the hydraulic cylinder 302 drives the special-shaped rod 303 and the annular frame 304 to move up and down, thereby realizing the up and down movement of the groove frame 305 and the brush cluster 306. The brush cluster 306 on the inner ring surface of the groove frame 305 cleans the surface of the emery roller body 1, and the brush cluster 306 on the outer ring surface of the groove frame 305 cleans the inner wall of the milling drum. The double-sided cleaning of the surface of the emery roller body 1 and the inner wall of the milling drum can be completed at the same time.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
