Adjustable grid bar type round large-grain seed grading device

Abstract

The invention discloses an adjustable grid bar type round large-grain seed grading device. The device comprises a box body, wherein the side walls on the left and right sides of the box body are respectively provided with arc-shaped grooves, a plurality of mounting holes are provided on mounting bars, a plurality of grid bars are arranged across both the arc-shaped groove, the left and right endsof each grid bar respectively extend out of the two arc-shaped grooves and are bent upward to form a lateral bending section, the plurality of bending sections on the same side are connected by adjusting plates, the plurality of lateral bending sections respectively run through a plurality of adjusting holes on the adjusting plates, the upper ends of the lateral bending sections at both ends of each grid bar are bent inward to form hooks, both ends of each grid bar are respectively inserted into the mounting holes on the mounting bars on both sides through the hooks, and the distance between the two adjacent grid bars is adjusted by adjusting the upper and lower positions of the adjusting plates to realize the classification of seeds in different sizes. Compared with the prior art, the adjustable grid bar type round large-grain seed grading device has the following advantages of being able to realize the classification of seeds in different size ranges and realize continuous and stepless adjustment of classification parameters.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an adjustable grid-type circular large-grain seed grading device. Background technique [0002] Grading is an important part of the post-harvest processing of agricultural products, providing conditions for subsequent mechanized processing and handling. Since there are certain differences in the size of crop seeds after they are harvested, in order to improve the quality of the seeds and meet the requirements of the later mechanized treatment process, it is usually necessary to classify the seeds and classify the harvested crop seeds according to the size requirements. It can screen out seeds of different grades with uniform size and size, and at the same time remove unfulfilled seeds, small particles of seeds and impurities in seeds. At present, most of the common seed grading and screening devices are fixed sorting, usually through the fixed sieve on the machine...

AI Technical Summary

Problems solved by technology

At present, most of the common seed grading and screening devices are fixed sorting, usually through the fixed sieve on the machine. The sorting of seeds of different sizes is determined by the shape and size of the sieve holes installed. When separating seeds of different sizes, it is necessary to replace the grading screens with different apertures according to the requirements. The installation and disassembly of the sieves will increase the intensity of the grading work and reduce the sorting efficiency. At the same time, the size of the sorting device is also affected by the parameters of the sorting device The size range of sorting is limited and the flexibility of adjustment is poor, which affects the subsequent mechanized processing. Therefore, it is important to design an efficient and adaptable grading device to improve the quality and effect of post-harvest grading processing. It also provides the necessary conditions for the mechanized treatment of seeds in the later stage
