Description

Technical Field

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

[0002] Grains and oils are a general term for cereals, beans, and other grains and oilseeds, as well as their processed and semi-processed products. They are a general term for the main foods of mankind. As the saying goes, food is the most important thing for people. Grains are a necessity for human survival and a special commodity that is related to the national economy and people's livelihood.

[0003] During grain and oil screening, a large amount of fine dust is generated. This dust not only pollutes the processing environment and affects the health of workers, but may also mix into the grain and oil products, reducing their quality and hygiene standards. Traditional screening devices mostly lack effective dust suppression mechanisms or have poor dust suppression performance, making it impossible to collect and treat the dust generated during screening in a timely manner. Therefore, a screening device for grain and oil processing is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a screening device for grain and oil processing, which has the advantages of easy dust reduction and strong practicality, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a screening device for grain and oil processing, comprising a base frame, a housing fixedly connected to the top of the base frame, a screen cylinder disposed inside the housing, a driving mechanism disposed on the top of the base frame, and a dust reduction mechanism disposed on one side of the screen cylinder.

[0006] Furthermore, the drive mechanism includes a first motor fixedly connected to the top of the base frame, a linkage component fixedly connected to one end of the first motor, a movable wheel fixedly connected to the outer surface of the housing, and one end of the linkage component connected to the movable wheel.

[0007] Furthermore, a feeding hopper is fixedly connected to one end of the shell, and a discharging hopper is fixedly connected to the other end, with both the feeding hopper and the discharging hopper being inclined.

[0008] Furthermore, the outer surface of the screen cylinder is provided with a roller groove, and the movable wheel is rotatably connected inside the roller groove.

[0009] Furthermore, a connecting frame is fixedly connected to the top of the housing, and a cleaning brush is fixedly connected to the bottom of the connecting frame, with the cleaning brush located at the top of the screen cylinder.

[0010] Furthermore, the dust suppression mechanism includes a collection box fixedly connected to the top of the base frame, a box door hinged to the front of the collection box, a fan fixedly connected to the top of the collection box, a collection pipe fixedly connected to the top of the fan, and a collection cover fixedly connected to one end of the collection pipe.

[0011] Furthermore, the collection hood is located inside the housing.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. This screening device for grain and oil processing, by setting a drive mechanism, transmits power to the movable wheel through the linkage component. The movable wheel rolls in the groove on the outer surface of the screen cylinder, thereby driving the screen cylinder to rotate stably. This drive method can realize the screening of grain.

[0014] 2. This screening device for grain and oil processing works in conjunction with a collection box, a fan, a collection pipe, and a collection hood. The fan generates suction, and the dust generated during the screening process is collected into the collection box through the collection pipe and the collection hood.

[0021] The drive mechanism 7 includes a first motor 701 fixedly connected to the top of the base frame 1. One end of the first motor 701 is fixedly connected to a linkage component 702, which can be composed of a belt and a pulley, or a sprocket and a chain. A movable wheel 703 is fixedly connected to the outer surface of the housing 2. One end of the linkage component 702 is connected to the movable wheel 703. A groove is formed on the outer surface of the screen cylinder 3, and the movable wheel 703 is tumbled inside the groove.
