Description

Adjustable vibration classifying screen for rice processing Technical Field The utility model relates to the technical field of grain processing, in particular to an adjustable vibration classifying screen for rice processing. Background The rice classifying screen is an important device for screening and classifying rice in the rice processing process, and is mainly used for classifying the rice according to the particle size, shape or other physical characteristics so as to facilitate subsequent processing, quality control and product packaging. Since the rice produced in different areas is affected by natural conditions such as climate and soil and variety differences, the sizes of the rice particles are obviously different, for example, guangnan county eight-treasure rice particles are generally larger than common rice, the length is about 7-8 mm, the width is about 3-4 mm, the thickness is about 2-3 mm, the rice particles are plump and round in appearance, when the sizes of sieve holes on the classifying screen are not matched with those of the eight-treasure rice, the sieve plate can not effectively sieve the eight-treasure rice and impurities, the eight-treasure rice possibly cannot smoothly pass through the sieve holes, the discharging speed is slowed down, and the follow-up sieving is influenced by accumulation on the sieve surface, so that the precise separation cannot be realized.
