Description

Technical Field

[0001] This utility model relates to the technical field of screening devices, specifically a screening device for grain processing. Background Technology

[0002] Grains encompass a wide range, including rice, wheat, millet, soybeans, and other miscellaneous grains. Cereals, including rice, wheat, millet, and soybeans, are mainly plant seeds and fruits, and are the traditional staple food of many Asian people. Rice, colloquially, refers to the "children" of rice plants, i.e., paddy rice. Rice is one of the most important food crops for humankind. Depending on its growing environment, rice can be divided into paddy rice, upland rice, and sea rice. Grain processing requires the use of rice screening devices.

[0003] When processing grains, they need to be screened first. Existing screening devices on the market do not have the function of easy disassembly of the filter screen. After a period of use, the mesh of the filter screen is easily blocked by impurities or grains and cannot be cleared. Over time, the working efficiency of the screen screen gradually decreases due to the blockage of the mesh, affecting the work of the workers. In addition, the feed inlet does not have a good feeding structure. When there is too much material, it is easy for the material to accumulate on the filter screen, affecting the screening effect. When there is too little material, the working efficiency is reduced.

[0004] In view of this, this technical solution proposes a screening device for grain processing, which can better solve the problems mentioned above. Utility Model Content

[0005] The technical solution adopted by this utility model is as follows: a screening device for grain processing includes a screening chamber and a filter screen. A support frame for supporting the screening chamber is installed below the screening chamber by springs. A vibration motor and a sludge outlet are provided on the lower left side of the screening chamber, and a discharge outlet is provided on the lower right side of the screening chamber.

[0006] The inner sidewalls of the screening chamber are detachably equipped with filter screen mounting frames at relative positions, and a positioning plate is hinged to the filter screen mounting frame. The filter screen is held between the lower cross section of the filter screen mounting frame and the positioning plate. The positioning plate and the lower cross section of the filter screen mounting frame are fixed by fastening bolts.

[0007] The screening chamber is detachably fitted with a cover plate, and a feeding mechanism is connected to the front of the inside of the cover plate. The feeding mechanism includes a discharge chamber that runs through the front of the inside of the cover plate, and a distribution chamber is connected above the discharge chamber. A rotating shaft is rotatably installed inside the distribution chamber, and a distribution plate is installed on the rotating shaft. A servo motor is installed on the side of the distribution chamber, and the output end of the servo motor is connected to the rotating shaft. A feed inlet is connected above the distribution chamber.

[0008] In a preferred embodiment, the lower part of the filter mounting bracket has an L-shaped structure, and the positioning plate has the same length and width as the lower cross section of the filter mounting bracket. The positioning plate is hinged to the vertical section of the filter mounting bracket via a hinge.

[0009] In a preferred embodiment, a material discharge space is provided between the rear of the filter screen and the rear of the inner wall of the screening chamber, and the material discharge space is located directly above the discharge port.

[0010] In a preferred embodiment, the filter mounting bracket is mounted on the inner wall of the screening chamber at a symmetrical position using a second bolt.

[0011] In a preferred embodiment, the lower cross section of the filter mounting bracket and the opposite surface of the positioning plate are provided with mounting grooves for placing the filter, and the filter is placed in the mounting grooves.

[0012] In a preferred embodiment, the material distribution plates are equidistantly distributed around the rotating shaft, and the material distribution plates are adapted to the interior of the material distribution bin.

[0013] In a preferred embodiment, the material distribution bin is provided with through slots at both the top and bottom, and the through slots are located inside the material discharge bin and the material inlet.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: it facilitates better installation of the filter screen, allows the filter screen to be disassembled and maintained without easily affecting the filtration effect of the filter screen, and at the same time allows for better feeding of grains, so that the grains are not prone to excessive accumulation on the filter screen, thus better ensuring the screening effect of the filter screen on the grains.

[0015] 1. In this utility model, by placing the filter screen into the mounting groove of the lower cross section of the filter screen mounting frame, and then flipping and snapping the positioning plate onto the side of the filter screen, the filter screen can be clamped between the lower cross section of the filter screen mounting frame and the positioning plate. Then, by fastening the bolts to lock the positioning plate on the lower cross section of the filter screen mounting frame, the position of the filter screen can be positioned. The filter screen can also be disassembled for easy maintenance and to better ensure the screening effect of the filter screen.

[0016] 2. In this utility model, the rotating shaft and the distribution plate are rotated by a servo motor. At this time, the grain inside the feed inlet is distributed between the distribution plates, and then a certain amount of material is fed to the filter screen, so that a large amount of grain does not accumulate on the filter screen, thus better ensuring the screening effect of the filter screen on the grain.
