Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rice processing impurity removing and feeding device. Background Art

[0002] In the grain processing industry, rice is the main grain product, and its purity and quality directly affect the health of consumers and food safety. In the rice processing, impurity removal and feeding are an important link, among which winnowing machines are widely used to remove light impurities in rice, such as husks, empty grains, grass clippings, and dust.

[0003] However, although the winnowing machine performs well in removing light impurities, in actual operation, there are still some impurities that are difficult to remove, especially iron filings and iron particles. These iron impurities may come from the machinery used in the rice production process, or be mixed in during transportation, storage, and fields. These iron impurities not only affect the purity of rice, but also may pose a potential threat to human health.

[0004] The main working principle of the air separator is to use the airflow to make the material and impurities have different movement trajectories in the air separation chamber, thereby achieving separation. However, since the density and shape of iron filings and iron particles are similar to those of rice, they may be sent out together with the rice during the air separation process, resulting in poor impurity removal effect, and often unable to effectively identify and separate these impurities.

[0020] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] It should be noted that when a part or component is considered to be "connected", "located", or "assembled" on another part or component, it may be directly disposed on the other part or component or there may be a central part or component at the same time. The terms "left", "right", "upper", "lower" and similar expressions used herein are for illustrative purposes only.

[0022] In a specific embodiment, Figure 1-4 As shown, a rice processing impurity removal feeding device comprises a feeding conveyor belt 1 and a winnowing machine 11, the feeding port of the winnowing machine 11 is located in the discharging area of ​​the feeding conveyor belt 1, mounting frames 2 are fixedly installed on opposite sides of the feeding conveyor belt 1, a vertical plate 3 located above the feeding conveyor belt 1 is fixedly installed between the two mounting frames 2, there is a gap between the bottom of the vertical plate 3 and the top of the feeding conveyor belt 1, a horizontal plate 4 located on the side of the vertical plate 3 close to the discharging area is fixedly installed between the two mounting frames 2, a magnetic part 5 is embedded in the bottom of the horizontal plate 4, and the gap between the magnetic part 5 and the feeding conveyor belt 1 is larger than the gap between the vertical plate 3 and the feeding conveyor belt 1.

[0023] like Figure 1 Figure 2 As shown, in this embodiment, a linear module 6 is fixedly installed on the top of the horizontal plate 4, an elastic member 8 is fixedly installed on the driving end of the linear module 6, and a circular block 7 covers the horizontal plate 4 and the linear module 6. The elastic member 8 is fixedly connected to the inner top wall of the circular block 7, and a cleaning member 9 is fixedly installed on the inner bottom wall of the circular block 7, one side of which is in contact with the bottom wall of the horizontal plate 4. The elastic member 8 drives the circular block 7 to move upward so that the cleaning member 9 always keeps in close contact with the bottom wall of the horizontal plate 4. After the magnetic member 5 is adsorbed with impurities such as iron filings, the linear module 6 can drive the cleaning member 9 to move and scrape off the iron filings on the magnetic member 5 to clean it. Specifically, the cleaning member 9 is U-shaped, the movable stroke of the driving end of the linear module 6 is greater than the length of the magnetic member 5, the length of the cleaning member 9 is greater than the width of the magnetic member 5, and the bottom wall of the magnetic member 5 is located in the same horizontal plane as the bottom wall of the horizontal plate 4. More specifically, a telescopic rod is fixedly installed inside the elastic member 8, and its two ends are respectively fixedly connected to the inner bottom wall of the circular block 7 and the driving end of the linear module 6, so that the driving end of the linear module 6 and the circular block 7 move synchronously, thereby preventing the driving end of the linear module 6 from causing the elastic member 8 to bend when driving the circular block 7 to move.

[0024] like Figure 3As shown, in the present embodiment, the side of the vertical plate 3 away from the linear module 6 is in a triangular shape. Since the rice is in a pile when transported to the feeding conveyor belt 1, designing the side of the vertical plate 3 away from the linear module 6 into a triangle can move the rice on the top of the pile to both sides, thereby increasing the paving area of ​​the rice and maximizing the efficiency while ensuring paving.

[0025] like Figure 4 As shown, in this embodiment, a mounting member 13 is detachably fixedly installed at the bottom of the horizontal plate 4, and the mounting member 13 is located on the side of the magnetic member 5 away from the vertical plate 3. A collecting plate 14 is fixedly installed on the side of the mounting member 13 close to the magnetic member 5, and the collecting plate 14 is adapted to the inner bottom wall of the cleaning member 9. The linear module 6 drives the cleaning member 9 to scrape off magnetic materials such as iron filings on the magnetic member 5, and then the cleaning member 9 continues to move. After being away from the magnetic member 5, the iron filings fall on the inner bottom wall of the cleaning member 9, and the collecting plate 14 is inserted into the cleaning member 9 and contacts the inner bottom wall of the cleaning member 9 to move the collected iron filings to the collecting plate 14. The iron filings can be conveniently poured out by removing the mounting member 13. The detachable fixed installation method of the horizontal plate 4 and the mounting member 13 can be fixed by bolts.

[0026] The above rice processing impurity removal and feeding device can be further optimized and / or improved according to actual needs:

[0027] It also includes a loading conveyor belt 12, which is inclined. The discharge end of the loading conveyor belt 12 is located above the feeding conveyor belt 1. The loading conveyor belt 12 replaces manual labor to transport rice to the feeding conveyor belt 1, which is more labor-saving and convenient.

[0028] A support frame 10 is fixedly installed on the feeding conveyor belt 1, and the support frame 10 is fixedly connected to the end of the cross plate 4 away from the mounting frame 2 to support the weight of the cross plate 4 so that the cross plate 4 can be maintained above the feeding conveyor belt 1 in parallel with the feeding conveyor belt 1.

[0029] In summary: before the rice enters the winnowing machine 11, it is subjected to a magnetic suction screening on the feeding conveyor belt 1. When the rice moves on the feeding conveyor belt 1, it passes through the bottom of the vertical plate 3 and is spread to both sides, so that the rice is thinly spread on the feeding conveyor belt 1, and then passes under the magnetic member 5. The iron filings, iron particles and other substances mixed in the rice are adsorbed by the magnetic member 5, and finally the rice is winnowed by the winnowing machine 11 to improve the purity of the rice.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention.
