Problems solved by technology

[0002] Rice is one of the staple foods of human beings. According to the analysis of modern nutrition, rice contains protein, fat, vitamin B1, A, E and various minerals. With the popularization of rice consumption, its treatment has become the top priority , the screening of rice is an important step in rice processing. Since different varieties of rice have different particle sizes, different screens need to be used for screening. The screens of existing screening equipment are not easy to replace and inconvenient. Different varieties of rice are screened; therefore, there is a need to improve existing techniques

Embodiment 1

[0020] see Figure 1-4 , a rice screening device with a dust removal function, comprising a base plate 1, a sliding seat 2 is movably installed on the base plate 1, a screening chamber 4 is installed above the sliding seat 2, and a dust removal chamber 6 is connected to one side of the screening chamber 4; The upper end of the screening chamber 4 is provided with a feed hopper 5, and the inner side of the screening chamber 4 is equipped with a first screening net 9 and a second screening net 10 at intervals, and a plurality of assembly holes 22 are uniformly arranged on the first screening net 9. , the first screen 9 and the screen chamber 4 are assembled and connected by bolts, two non-penetrating positioning grooves 23 are arranged at intervals on the first screen 9, and the interior of the screen chamber 4 is slidably installed with a positioning block 26 via a lifting hydraulic cylinder 25, The positioning block 26 is matched with the positioning groove 23, and a side of t...

Embodiment 2

[0029] In order to improve the screening effect of the screening chamber 4, this embodiment is improved on the basis of Embodiment 1. The improvement is: two assembly seats 27 are arranged at intervals on the bottom plate 1, and the assembly seats 27 are respectively located on the sides of the sliding seat 2. Both sides, the both sides of slide seat 2 are fixedly connected with push rod 28, and cam 30 is installed in one of assembly seat 27, and cam 30 transmission is connected with motor, and return spring 29 is installed in the other assembly seat 27, and slide seat 2 two The side push rod 28 extends into the corresponding assembly seat 27 and is in contact with the cam 30 and the return spring 29 respectively. Under the action of the return spring 29, the push rod 28 is always in contact with the cam 30, thereby driving the The sliding seat 2 slides back and forth along the bottom plate 1 to promote the screening effect of rice.

Abstract

The invention discloses a rice screening device with a dust removal function. The rice screening device with the dust removal function comprises a bottom plate; a sliding base is movably installed onthe bottom plate; a screening cavity is assembled above the sliding base; one side of the screening cavity is connected with a dust removal cavity; according to the rice screening device, due to multi-directional connection between a dust removal pipe and the screening cavity, the dust removal effect of rice is ensured, and the multi-layer screening effect of the rice is ensured through a first screening net and a second screening net which are arranged at intervals; in addition, the screening nets and the screening cavity are convenient to disassemble, assemble and replace, and therefore different screening nets can be conveniently selected according to different varieties of rice; besides, the screening cavity is driven to reciprocate in the horizontal direction and the vertical direction, the rice can be spread on the screening nets conveniently, and the screening effect is promoted.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a rice screening device with dust removal function. Background technique [0002] Rice is one of the staple foods of human beings. According to the analysis of modern nutrition, rice contains protein, fat, vitamin B1, A, E and various minerals. With the popularization of rice consumption, its treatment has become the top priority , the screening of rice is an important step in rice processing. Since different varieties of rice have different particle sizes, different screens need to be used for screening. The screens of existing screening equipment are not easy to replace and inconvenient. Different varieties of rice are screened; therefore, it is necessary to improve the existing technology. Contents of the invention [0003] The object of the present invention is to provide a kind of rice screening device with dust removal function, to solve the problems raised in th...
