Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a gravel cleaning device for rice processing. Background Art

[0002] Rice is a finished product made from rice grains through a series of processes, including cleaning, husking, milling, and finishing. Rice contains nearly 64% of its nutrients and over 90% of the nutrients required by the human body. However, during the harvesting process, rice is easily contaminated with impurities and small stones. To ensure the quality and safety of the finished rice, the rice must be removed from the rice. Currently, existing devices for rice removal often accumulate rice on the screening plates, preventing the rice from being fully separated from the stones. This results in poor stone removal and compromises rice quality. Utility Model Content

[0003] The utility model provides a gravel cleaning device for rice processing, which aims to solve the problem that rice is easily accumulated on a screening plate in the device, thereby failing to fully separate rice from stone particles, resulting in poor stone removal effect and affecting rice quality.

[0004] The technical solution is: a gravel cleaning device for rice processing, including a box body, a hopper connected to the top of the box body, a flow limiting plate fixedly connected to the bottom of the hopper, a screening plate fixedly connected to the side of the box body close to the hopper, the screening plate is inclined with the left side higher and the right side lower, and screening hole 1 and screening hole 2 are respectively opened on the screening plate, the aperture of screening hole 1 is smaller than the aperture of screening hole 2, a guide plate located below the screening plate is provided on the inner wall of the box body, and a bellows is provided on the side wall of the box body.

[0005] Furthermore, the flow limiting plate and the flow guide plate are both arranged to be inclined with the left side lower and the right side higher.

[0006] Furthermore, the bottom of the box body is designed to be an inverted V shape.

[0007] Furthermore, an outlet 1 is provided on the side of the box body close to the screening plate, an outlet 2 is provided on the side of the box body close to the guide plate, and an outlet 3 and an outlet 4 are respectively provided on the two side walls of the box body away from the hopper.

[0008] Furthermore, it also includes evenly distributed dispersion blocks, which are arranged on the screening plate and are designed in a triangular shape.

[0009] Furthermore, it also includes a mounting base, which is fixed to the box body. A motor is provided on the mounting base. A rotating shaft is rotatably connected to one side of the box body close to the screening plate. The output shaft of the motor is connected to the rotating shaft. A cam that cooperates with the screening plate is fixed to the rotating shaft.

[0010] The beneficial effects are as follows: 1. The flow limiting plate set in the hopper reduces the amount of rice entering the box, thereby preventing excessive accumulation of rice on the screening plate and affecting the stone removal effect;

[0011] 2. The vibrating screening plate disperses the rice, causing the heavier stones to sink to the bottom layer and the lighter rice to float to the upper layer, promoting automatic grading;

[0012] 3. The rice in the flow process is dispersed by the dispersion blocks arranged on the screening plate to prevent the flowing rice from piling up. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The present invention will be described in detail below with reference to the accompanying drawings.

[0018] Example 1: A rice processing gravel cleaning device, referring to Figure 1-Figure 3 , including a box body 1, the bottom of the box body 1 is designed in an inverted V shape, the top of the box body 1 is connected to a hopper 2, the bottom of the hopper 2 is fixedly connected to a limiting flow plate 21, the upper part of the box body 1 is fixedly connected to a screening plate 3, the screening plate 3 is inclined with the left higher and the right lower, and the left and right parts of the screening plate 3 are respectively provided with a screening hole 1 31 and a screening hole 2 32, the aperture of the screening hole 1 31 is smaller than the aperture of the screening hole 2 32, a guide plate 33 is provided on the left wall of the box body 1, the guide plate 33 is located below the screening plate 3, and a bellows 34 is provided on the right side of the box body 1, the limiting flow plate 21 and the guide plate 33 are both inclined with the left lower and the right higher, an outlet 11 is provided on the upper right side of the box body 1, an outlet 2 12 is provided on the upper left side of the box body 1, and an outlet 3 13 and an outlet 4 14 are respectively provided on the left and right sides of the lower part of the box body 1.

[0019] Reference Figure 2 , also includes evenly distributed dispersion blocks 4, the evenly distributed dispersion blocks 4 are arranged on the screening plate 3, and the dispersion blocks 4 are designed in a triangular shape.

[0020] Reference Figure 3 , and also includes a mounting base 5, the mounting base 5 is fixedly connected to the rear side of the box body 1, a motor 51 is provided on the mounting base 5, and a rotating shaft 52 is rotatably connected to the upper part of the box body 1. The output shaft of the motor 51 is connected to the rotating shaft 52, and a cam 53 is fixed on the rotating shaft 52, and the cam 53 cooperates with the screening plate 3.

[0021] When in use, the motor 51 is started, and the output shaft of the motor 51 drives the rotating shaft 52 to rotate, and the rotating shaft 52 drives the cam 53 to rotate, and the cam 53 continuously pushes the screening plate 3 to make the screening plate 3 vibrate up and down, and the rice is put into the box body 1 through the hopper 2, and the rice entering the box body 1 is reduced by the flow limiting plate 21 provided in the hopper 2, so as to prevent excessive accumulation of rice on the screening plate 3 and affect the stone removal effect. The rice entering the box body 1 falls on the left part of the screening plate 3, and the rice is dispersed by the vibrating screening plate 3, and the stone particles with higher specific gravity sink to the bottom layer, and the rice with lower specific gravity floats to the upper layer, thereby promoting automatic grading. At the same time, since the screening plate 3 is tilted with the left higher and the right lower, the rice on the screening plate 3 flows from left to right and passes through the dispersion blocks 4 provided on the screening plate 3. The rice in the flow process is dispersed to prevent the flowing rice from piling up. When the rice passes through the left part of the screening plate 3, the gravel smaller than the rice in the rice falls onto the guide plate 33 and is discharged through the second outlet 12. When the rice passes through the right part of the screening plate 3, the rice falls under the screening plate 3, and the gravel larger than the rice is discharged through the first outlet 11. The bellows 34 is started to generate a wind field. Since the weight of equal volume of rice is less than the weight of stone, the equal volume of rice is blown to the left part of the box body 1 in the process of passing through the wind field. Since the bottom of the box body 1 is designed in an inverted V shape, the rice is discharged through the third outlet 13, thereby obtaining rice without stones, and the stones fall vertically to the right part of the box body 1, so that the rice is discharged through the fourth outlet 14.

[0022] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
