Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to a grain collecting and filtering device for agriculture. Background Art

[0002] Cereals are the fruits of plants (such as wheat, corn and rice) from which starchy seeds are obtained and suitable for food; they also refer to the seeds of productive or grain plants (in their unprocessed state).

[0003] Before storing the grains, they need to be exposed to the sun and dried in the threshing yard. After the exposure, the grains need to be collected. Currently, most rural areas clean and pile up the grains after drying, and then use transport vehicles to transport the grains. However, since the cleaned and piled grains are easily mixed with a large amount of dust and mud and sand of various sizes, the grains mixed with mud and dust need to be screened and filtered before they can enter the grain storage bin.

[0004] The existing grain collecting device, for example, the Chinese utility model patent with application number 2021225752826 discloses a grain collecting device for agricultural production, comprising a bottom plate (1), two groups of symmetrical clamping plates (3) are installed on the top of the bottom plate (1), spring steel sheets (4) are installed inside the clamping plates (3), a screen frame (7) and a material receiving frame (6) are installed between the two groups of spring steel sheets (4), a symmetrical first support seat (15) is installed on the bottom plate (1) below the material receiving frame (6), and two symmetrical first support seats (15) are rotatably provided with two symmetrical clamping plates (15) distributed up and down. A rotating shaft (14), both ends of the rotating shaft (14) are equipped with rotating arms (13), a worm wheel (16) is installed on the rotating shaft (14), the worm wheel (16) is meshed with a worm (17), a transmission shaft (18) is installed at the center of the two worms (17), a side gear (19) is installed in the middle of the transmission shaft (18), a rectangular bracket (23) is installed on the side of the top of the bottom plate (1) away from the first support seat (15), a moving frame (25) is slidably provided on the upper end of the rectangular bracket (23), and symmetrical hooks (26) are installed on the symmetrical inner sides of the moving frame (25).

[0005] When the above-mentioned grain collecting device is used for grain collection and screening, the collection and screening effect is poor, and some larger dirt blocks in the grains need to be manually screened, which is inefficient; and a large amount of dust is easily generated during screening. When people are close to collecting rice, they need to cover their mouths and noses to avoid inhaling dust into the body, which affects the collection operation. Summary of the invention
