AI Technical Summary

Technical Problem

Existing mechanical harvesting devices for camel hair quinoa seeds cannot be graded by quality, resulting in mixed seeds, increased manual sorting steps, extended processing cycles, and seeds that are easily damaged and may be lost due to their light weight. This makes it difficult to meet the immediate seed needs of different scenarios.

Method used

Design a hand-controlled camel hair quinoa seed harvesting device. It uses a V-shaped bucket and a slot structure to fix the mother plant, and a zigzag channel to grade the seeds. Combined with the negative pressure of the air pump and the magnetic block sieve plate design, it can realize seed grading and impurity removal by weight, reducing damage and spillage.

Benefits of technology

It improves harvesting efficiency and seed purity, reduces labor intensity, meets the quality requirements of different scenarios, and reduces overall operating costs and seed loss rate.

Abstract

The invention discloses a manual control type camel hair chenopodium album seed harvesting device which comprises a collecting part used for harvesting seeds from stock plants, a grading part used for grading the harvested seeds according to the weight is arranged at one end of the collecting part, and an impurity removing part used for pretreating the seeds before grading is arranged in the grading part; according to the seed grading device, a directional airflow field is formed through an L-shaped channel, a symmetrical and staggered distribution mode of the collecting pieces is combined, accurate grading is achieved through kinetic energy differences of seeds of different weights, and the differentiated requirements of different scenes such as breeding and ecological restoration for the seed quality are met; seeds are prevented from impacting and damaging seed coats, the seeds can be guided to accurately gather into the collecting groove, the inclined guiding of the flow guide block in the collecting cavity is matched, it is ensured that the seeds are smoothly discharged from the discharging pipe without residue accumulation, fine light impurities in secondary screening can be synchronously removed through a negative pressure adsorption structure of the ox horn type guide block and the air pump, the purity of the graded seeds is improved, and the quality of the graded seeds is improved. And subsequent treatment procedures are reduced.
