Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a fast grain sieving machine. Background Technology

[0002] The grain impurity removal rapid screening agricultural machine is simple in design and highly efficient, capable of processing various types of grains such as wheat, corn, and soybeans. Its high efficiency is reflected in its ability to process large quantities of grain quickly while maintaining low energy consumption and ease of operation. The grain impurity removal rapid screening agricultural machine is a specialized agricultural machine designed to remove impurities from grains.

[0003] In existing high-speed grain screening machines, grain is evenly fed onto the screen surface. Under vibration, the grain particles are stratified according to their size on the screen surface. Smaller impurities, such as dust and fine sand, fall through the screen holes, while larger grain particles remain on the screen surface and continue to move forward. However, in actual use, when there is no quantitative feeding, the vibration system will be subjected to uneven loads. Sometimes, excessive grain flow will cause the vibrating components to bear excessive pressure, easily leading to accelerated wear, deformation, or even damage. In the long run, this will significantly shorten the service life of the agricultural machinery and increase maintenance costs. Therefore, to address the above-mentioned problems, a high-speed grain screening machine for impurity removal is proposed. Utility Model Content

[0037] Working Principle: First, grain enters the device through the feed inlet and falls into the feed box 4. The motor 6 starts, driving the drive wheel 7 to rotate. Simultaneously, the drive wheel 7 rotates the baffle plate 5 inside the feed box 4, ensuring even grain distribution. This drives the belt 8 and driven wheel 15 to work together, causing the rotating rod 13 to rotate. The rotation of the rotating rod 13 drives the elliptical wheel 14, which in turn affects the vibration of the screen plate 12, promoting even grain distribution and extending the device's lifespan. As the grain moves on the screen plate 12, some grain passes through and enters the collection box 22 below. Impurities remain outside the screen plate 12 and flow through the baffle 16 into the storage box 18 for collection. The angle and position of the screen plate can be adjusted as needed to accommodate different types of grain and screening requirements. The design of the limiting components ensures the screen plate will not detach during operation, maintaining stability.

[0038] After screening, the processed grain flows into the collection box 22 through the chute 26. The collection box 22 can then slide freely within the chute for easy cleaning and replacement. When the collection box 22 is pulled out, the rotating plate 24 provides support to prevent it from tipping over. Operators can easily remove the collection box for loading and transporting the grain. Throughout the process, the protective shell 28 protects the internal components, ensuring the safe operation of the equipment. The adjustable length of the support legs 19 allows the equipment to adapt to different working environments and maintain stability. Through this series of operations, the grain impurity removal fast screening agricultural machine achieves efficient and convenient grain screening and impurity removal, improving the efficiency of agricultural production.
