Fixed-grain packaging device for corn seeds

Abstract

The invention discloses a fixed-grain packaging device for corn seeds. The fixed-grain packaging device for the corn seeds comprises a pre-selecting mechanism and a separate packaging mechanism; the pre-selecting mechanism comprises a first conveying belt, a seed collecting cylinder and an air blower, the seed collecting cylinder is provided with a first through hole and a second through hole, thefirst conveying belt is used for conveying the corn seeds, one end of the first conveying belt penetrates through the first through hole to stretch into the seed collecting cylinder, and the air blowing direction of the air blower is obliquely formed upwards and faces the second through hole; and the separate packaging mechanism comprises a second conveying belt, a hopper and a third conveying line, the second conveying line is located under the seed collecting cylinder and is close to the seed collecting cylinder, a soft matrix is fixedly connected to the surface of the second conveying lineand provided with multiple groups of containing grooves, each group comprises a plurality of the containing grooves, the hopper is located under the tail end of the second conveying line, and the third conveying line is located under the hopper and used for conveying packaging boxes. According to the fixed-grain packaging device for the corn seeds, precise fixed-grain packaging of the corn seedscan be achieved, the structure is simple, and the fixed-grain packaging device for the corn seeds is suitable for being popularized.

Description

technical field [0001] The invention relates to the technical field of seed packaging, in particular to a corn seed sizing packaging device. Background technique [0002] At present, crop seeds are generally packaged by weight before being sold, and are also sold by weight when sold. Because the size and weight of each seed are different, the number of seeds contained in the seed packaging bag of the same weight is different. Knowing the weight can only make a simple estimate of the number of seeds. In the past, such packaging was not a big problem, but with the comprehensive promotion of single seed precision sowing technology, the number of seeds required per mu of farmland is determined. This traditional method of packaging by weight has caused great trouble to farmers, because it is impossible to accurately estimate the number of bags of seeds needed, which will cause waste or shortage of seeds. Therefore, fixed grain packaging has become the development trend of seed ...

AI Technical Summary

Problems solved by technology

[0003] Among the common crop seeds, corn seeds are a special kind. On the one hand, the single seed precision sowing technology of corn has developed better. On the other hand, corn seeds have various shapes, and there are certain difficulties in accurate counting.

[0004] In order to solve the shortcomings of traditional packaging methods, Chinese patent "CN201010297202.9" proposes a "seed weighing system and weighing method with online counting and weight compensation functions". It consists of a sampler, a packing scale, a packing machine and a sorting scale. The number of seeds is counted and sorted by a counting machine. Although the purpose of fixed grain packaging can be achieved, its structure is complex, bulky, and costly. It is only suitable for Seed manufacturers, but not all farmers
