Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a sieving device for filtering impurities in rice. Background Technology

[0002] Rice refers to processed paddy rice (Oryza sativa), a plant belonging to the Poaceae family. It is one of the world's most important food crops, especially in Asia, where it serves as a primary food source, supporting the basic diet of billions of people. Rice requires filtration to remove impurities, which necessitates the use of sieving devices.

[0003] In general, rice impurity filtration screening equipment shakes the rice relatively gently during screening, which reduces the rice's fluidity and makes it easy to clog the filter holes. Furthermore, the direct impact of the rice on the filter plate causes wear and tear on the equipment, reducing its service life. Utility Model Content

[0004] In view of the problems in existing patents, the existing rice impurity filtration screening equipment is generally set up with relatively gentle shaking when screening rice, which reduces the flowability of rice and makes it easy to clog the filter holes. In addition, the direct impact of rice on the filter plate will cause wear and tear on the equipment, reducing its service life. This utility model provides a rice impurity filtration screening equipment.

[0023] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0024] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a sieving device for filtering impurities in rice.

[0025] The specific technical solution includes a housing 1; a screening assembly 2, which is installed inside the housing 1 and includes a screening plate 21, a corrugated plate 22, a first filter hole 23, a baffle 24, a return spring 25, and a damper 26. The screening plate 21 is installed inside the housing 1, the corrugated plate 22 is fixedly installed inside the screening plate 21, the baffle 24 is slidably connected inside the screening plate 21, the return spring 25 and the damper 26 are both fixedly installed inside the screening plate 21, and the return spring 25 is sleeved on the damper 26. The other end of the return spring 25 and the damper 26 are both fixedly installed on the baffle 24. The first filter hole 23 is opened on one side of the corrugated plate 22; and a drive mechanism 3, which is installed on one side of the housing 1 and is used to provide power support for the shaking of the screening plate 21.

[0026] The drive mechanism 3 includes a rotating rod 31, a gear 32, a limiting block 33, a rack 34, and a drive cylinder 35. One end of the rotating rod 31 is fixedly installed on the screening plate 21, and the other end of the rotating rod 31 passes through the housing 1 and is fixedly installed on the gear 32. The limiting block 33 is fixedly installed on the rotating rod 31, and the inner side of the limiting block 33 is attached to the outer side of the gear 32. A V-shaped plate 4 is fixedly installed on one side of the housing 1. A second filter hole 5 is opened on one side of the V-shaped plate 4. The rice can be simply filtered through the second filter hole 5.

[0027] A collection box 6 is fixedly installed on one side of the inner wall of the box 1. A feed inlet 7 is opened on one side of the collection box 6. The collection box 6 is connected to the V-shaped plate 4. A dust suction plate 8 is fixedly installed on one side of the inner wall of the box 1. A dust suction hole 9 is opened on one side of the dust suction plate 8. An air pump 10 is fixedly installed on one side of the box 1. One end of the air pump 10 is connected to the dust suction plate 8 through a pipe. Air outlets 11 are opened on both sides of the box 1. The air pump 10 can suck out the dust floating inside the box 1.

[0028] In use, rice is placed into the box 1 and then onto the V-shaped plate 4. The rice is filtered along the V-shaped plate 4, allowing it to enter the sieve plate 21. Then, the drive cylinder 35 is activated, which moves the rack 34, causing the rotating rod 31 on one side of the gear 32 to rotate. This rotating rod 31 drives the sieve plate 21 to swing, allowing the rice inside the sieve plate 21 to move back and forth along the corrugated plate 22. The characteristics of the reset spring 25 and damper 26 ensure that the rice is cushioned and damped when it contacts the inner walls of the sieve plate 21. The plate protects the rice and allows it to move back and forth along the corrugated plate 22, achieving a second filtration of the rice for a more thorough filtration. The curved design guides the rice along a specific path, reducing its residence time on the filter plate, enhancing its flowability, and preventing blockage. The curved shape also reduces direct impact and wear on the filter plate, thus improving the equipment's durability and extending its service life. During the filtration process, the air pump 10 can be activated to expel floating dust inside the housing 1 through the dust suction plate 8, preventing dust from floating into the air when the housing is opened.
