[0002] my country's grain conveying equipment industry has evolved from manual operation to mechanization and automation. With continuous technological progress and industrial upgrading, the industry's technical level has been continuously improving, and the types and specifications of products have been constantly enriched. Grain conveyors include various types such as belt conveyors, screw conveyors, bucket elevators, and scraper conveyors, which are suitable for material conveying in the process of grain production, processing, and transportation. As consumers become more aware of food safety and environmental protection, their requirements for the performance and quality of grain conveying equipment are also increasing. In the future, the grain conveying equipment industry will continue to develop towards automation, intelligence, and high efficiency.

[0003] A grain conveying mechanism with screening function is disclosed in patent document CN218260958U. By setting a fixed box, when the grain needs to be screened, the grain can be poured into the fixed box. At this time, the drive motor can be started to drive the rotating rod to rotate. The rotating rod can cause the second connecting plate to drive the protective pad to beat the surface of the filter screen. The vibration generated by the beating of the filter screen can quickly filter the grain on the surface, realizing the screening effect and preventing the grain from being mixed with roots, stems and weeds, which are difficult to screen and affect the quality of the grain.

[0004] However, this grain conveying mechanism with screening function is prone to blockage at the feed inlet during feeding, making it difficult for grain to enter. Utility Model Content

[0026] The bottom of the conical barrel 101 is provided with a spiral rotation mechanism, which includes: a transmission barrel 3, a transmission motor 301, a spiral blade 302 and a screw 303. The transmission barrel 3 is fixedly installed at the bottom of the conical barrel 101, the transmission motor 301 is fixedly installed on the left side of the transmission barrel 3, the screw 303 is fixedly installed at the output end of the transmission motor 301, and the spiral blade 302 is fixedly installed on the surface of the transmission motor 301.

[0027] A grain distribution box 5 is fixedly installed on the right side of the grain outlet pipe 4. The grain distribution box 5 is equipped with a screening mechanism, which includes a grain leakage plate 502, a drawer 503 and a filter plate 504. The grain leakage plate 502 is fixedly installed at the bottom of the inside of the grain distribution box 5, the drawer 503 is installed at the bottom of the grain leakage plate 502, and the filter plate 504 is slidably installed on the right side of the inside of the grain distribution box 5.

[0028] Example 2: Based on Example 1, a vertical grain outlet pipe 201 is fixedly installed at the bottom of the conical barrel 101. The vertical grain outlet pipe 201 connects the grain outlet and grain inlet of the conical barrel 101 and the transmission barrel 3. An inclined grain outlet pipe 402 is fixedly installed at the bottom of the transmission barrel 3. The inclined grain outlet pipe 402 connects the grain outlet and grain inlet of the transmission barrel 3 and the grain outlet pipe 4. A grain outlet pipe 4 is fixedly installed at the bottom of the transmission barrel 3. A blower 401 is fixedly installed on the left side of the grain outlet pipe 4.

[0029] Example 3: Based on Example 1 and Example 2, a grain baffle 501 is fixedly installed on the top left side of the grain leakage plate 502. The grain baffle 501 only allows items smaller than the gap volume to enter the grain distribution box 5 from the grain outlet pipe 4. The filter plate 504 is divided into two filter plates 504 with different filter screen sizes, dividing the grain distribution box 5 into the first grain distribution box, the second grain distribution box, and the third grain distribution box.

[0030] Working principle: After the grain is put into the feed hopper 1, the motor 103 drives the motor rod 104 to rotate, which causes the stirring rod 105 to drive the extension rod 106 and the cleaning scraper 107 to clean and stir the grain and the hopper wall inside the feed hopper 1. After that, the grain passes through the conical hopper 101 and enters the vertical grain outlet pipe 201. From the vertical grain outlet pipe 201, the grain enters the transmission hopper 3. The transmission motor 301 drives the screw 303 to rotate, which causes the spiral blade 302 to transport the grain on the surface of the screw 303 to the inclined grain outlet pipe 402. From the inclined grain outlet pipe 402, the grain enters the grain outlet pipe 4. Then, the blower 401 sends the grain to the grain distribution box 5. After entering the grain distribution box 5, the grain first contacts the grain baffle plate 501 for filtration. The filtered grain enters the drawer 503 through the grain leakage plate 502. The remaining grain continues to enter the filter plate 504 for secondary filtration to prevent the grain from being mixed with roots, stems and weeds, which would make it difficult to screen and affect the quality of the grain.
