The method comprises the steps of screening large-grained substances through a drum screen, enabling the screened large-grained substances to fall into a vibrating screen for vibration layering, enabling the rice hulls with low specific gravity to be located on the uppermost layer, and sucking the rice hulls through a hull sucking machine to separate paddy from the rice hulls. The utility model adopts the assembly and matching, has compact structural design, reasonable function matching and quick and efficient screening, separates the rice hulls and the brown rice, and is suitable for livestock and poultry. The utility model has simple structure, low manufacturing cost, quick and efficient screening, can effectively realize the separation of the paddy (brown rice) and the rice hull, and meets the requirements of livestock and poultry feeds.

The rice crusher comprises a conveyor belt, wherein the conveyor belt is obliquely arranged, the conveyor belt is positioned below a rotary screen and a vibrating screen, and the conveyor belt is used for conveying crushed rice after screening. The fine brown rice after large-particle substances are screened by the drum screen and the vibrating screen, and the large-particle brown rice on the vibrating screen after the rice hulls are sucked by the shell sucking machine falls into the conveying belt and is finally conveyed to the brown rice aggregate, so that the screening efficiency of the paddy rice hulls is further improved.

According to the utility model, the shell suction port is arranged below the shell suction machine, the shell outlet is arranged above the shell suction machine, the height of the shell suction machine can be adjusted, the distance between the shell suction port and the vibrating screen is further adjusted, and the shell suction machine is driven by the motor to suck rice husks on the vibrating screen. The height of the shell suction machine is adjustable, so that the distance between the shell suction opening and the vibrating screen is adjusted, and the operation efficiency of the shell suction machine for absorbing rice hulls is effectively guaranteed.

The vibrating screen is provided with a plurality of material homogenizing baffle rods which are arranged in parallel, the vibrating screen is provided with an aggregate concentration baffle plate, and the aggregate concentration baffle plate is used for concentrating oversize materials of the vibrating screen. The material homogenizing baffle rod and the material collecting centralized baffle plate are arranged on the vibrating screen, so that oversize materials on the vibrating screen are uniform and centralized, and the operation efficiency of the shell suction machine for absorbing rice hulls is effectively ensured.

Detailed Description

As shown in fig. 1 and 2, the rice husk removing machine comprises a frame 1, wherein a rotary screen 6 and a vibrating screen 13 are mounted on the frame 1, the rotary screen 6 and the vibrating screen 13 are both arranged in an inclined direction, the vibrating screen 13 is positioned below the rotary screen 6 in an inclined manner, a husk removing machine 26 is arranged above the lower end part of the vibrating screen 13, the husk removing machine 26 is used for removing rice husks on the vibrating screen 13, the rotary screen 6 is driven by a motor 2, and the vibrating screen 13 is driven by a motor 9. The front end of the drum screen 6 is provided with a feed hopper 7.

Including conveyer belt 23, conveyer belt 23 slant setting, conveyer belt 23 is located the below of drum sieve 6 and shale shaker 13, conveyer belt 23 is used for the broken corn after the conveying screening.
