Description

Technical Field

[0001] The utility model relates to the field of rice processing, and more specifically to a rice bran screening device for rice rolling. Background Art

[0002] Rice can be said to be an indispensable food in our lives, so the requirements for rice processing are relatively strict. Rice crushing is one of the necessary steps in the rice processing process. In order to ensure the quality of the final product during rice crushing, a rice bran screening device is often used in the rice crushing process to screen out the rice bran.

[0003] Patent No. CN220716652U in the prior art discloses a rice bran screening mechanism for a rice milling device, which belongs to the field of rice processing. The rice bran screening mechanism for a rice milling device comprises a main body mechanism, an adjusting mechanism is installed at the outer end of the main body mechanism, and the outer end of the adjusting mechanism is slidably connected with a connecting mechanism. The adjusting mechanism comprises an adjusting protrusion, which is slidably connected to the outer side of the main body mechanism, and the outer end of the adjusting protrusion is slidably connected with a slide, and an impact head is installed at the front end of the slide, and a limit rod is installed at the end of the slide away from the impact head. The limit rod is a T-shaped structure, and a spring member is sleeved on the outer end of the limit rod, which can be realized by allowing the adjusting protrusions with raised circular structures at both ends to collide with the impact slide, so that the screening hopper can effectively simulate the manual use of the screen drum to screen the rice bran, which distinguishes the problem of poor effect of simple rotation screening, and allows the device to screen the rice bran more thoroughly, thereby improving the screening effect of the device.

[0004] However, the patents under the existing technology have the following disadvantages:

[0005] (1) The rice bran screening mechanism for a rice milling device of the utility model is not provided with a buffer component. Due to the absence of the buffer component, the rice bran screening mechanism may be subjected to a large impact force when operating at a high speed, resulting in increased wear of equipment components and shortening the service life of the equipment. The absence of the buffer component may make it impossible to effectively alleviate the vibration generated during the milling process, thereby increasing the overall vibration of the equipment and affecting the stable operation of the equipment.

[0006] (2) The rice bran screening mechanism of the rice milling device of this utility model adopts vibration filtering to screen out rice bran. The power required for vibrating the bran screening is relatively large, and the corresponding energy consumption is also high. The noise and vibration generated by the dynamic bran screening during operation are relatively large, which may affect the surrounding environment and equipment. Utility Model Content
