Description

Technical Field

[0001] This utility model relates to the technical field of raw grain cleaning device for rice processing, and more particularly to a raw grain cleaning device for rice processing. Background Technology

[0002] Rice processing is the process of turning paddy into edible rice, involving several key steps to ensure the quality, taste, and safety of the final product. The first step in rice processing is raw grain cleaning, which aims to remove impurities and stones from the paddy.

[0003] Chinese patent CN220829041U discloses a raw grain cleaning device for a rice processing plant. The device includes a main body with a grain storage tank on top. A drying chamber is located on the top of the grain storage tank, and a hopper is installed on the drying chamber. A chute is formed in the hopper, and a feeding plate is slidably installed within the chute. A motor is mounted on one side of the grain storage tank, with a motor shaft, a connecting rod, and a motor wheel mounted on the motor shaft. In this invention, the feeding plate, connecting rod groove, and connecting rod structure cause the motor shaft to rotate, driving the connecting rod to rotate. Under the action of the connecting rod groove and connecting rod, the feeding plate reciprocates within the chute, causing the feeding hopper and the feeding plate's discharge opening to switch between opening and closing. This ensures that the amount of raw grain falling in the same amount of time remains consistent, preventing incomplete drying due to excessive grain falling and over-drying due to insufficient grain falling, thus avoiding unstable drying results.

[0004] Existing raw grain cleaning devices for rice processing suffer from problems such as using only a single filter layer to remove large particulate impurities from the raw grain, resulting in poor filtration and screening effects and a tendency to clog. To overcome these disadvantages, this invention provides a raw grain cleaning device for rice processing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a raw grain cleaning device for rice processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a raw grain cleaning device for rice processing, comprising a base, a support frame provided on the front side of the base, the support frame having a U-shaped structure, the bottom front end of the support frame being hinged to the base, a rotating assembly for driving the support frame to rotate around the hinge on the rear side of the base, a rotating shaft rotatably connected to the front side of the support frame, a filter cylinder fixedly connected to the front end of the rotating shaft, a driving assembly for driving the rotating shaft to rotate on the support frame, the filter cylinder having multiple cylindrical filter layers with progressively smaller pore sizes from the inside to the outside, a recycling bin fitted around the outside of the filter cylinder, the top of the recycling bin being fixedly connected to the support frame, an opening on the rear side of the recycling bin, the size of the opening being adapted to the rotating shaft and covering the rotating shaft, the front side of the filter cylinder having an open structure and being detachably connected to a first sealing cap, and the front side of the recycling bin having an open structure and being detachably connected to a second sealing cap.

[0014] 1. In this solution, a base, support frame, rotating shaft, filter cylinder, recovery bucket, first sealing cover, sealing ring, second sealing cover, cavity, second pulley, drive shaft, third pulley, and second drive belt are installed. The raw grain to be processed is added to the innermost layer of the filter cylinder. The second motor drives the drive shaft and third pulley to rotate. Through the transmission action of the second drive belt, the second pulley and rotating shaft are driven to rotate, and the filter cylinder rotates accordingly.

[0040] The working principle of this utility model is as follows: The raw grain to be processed is added into the innermost layer of the filter cylinder 14. The second motor 24 is started, which drives the transmission shaft 21 and the third pulley 22 to rotate. Through the transmission action of the second transmission belt 23, the second pulley 20 and the rotating shaft 13 are driven to rotate, and the filter cylinder 14 rotates accordingly.

Through the linkage action of the connecting seat 3, the fixed seat 6, and the connecting rod 7, the support frame 2 is tilted forward as a whole. The second sealing cover 18 and the first sealing cover 16 are removed respectively, and the filtered raw grain in the recycling bin 15 and the impurities in the filter cylinder 14 are poured out in sequence.
