Direct grain picking device for quinoa harvester

Abstract

The invention belongs to the field of agricultural machinery and particularly relates to a direct grain picking device for a quinoa harvester. The device comprises a grain picking roller 1, a grain picking bent knife roller 11, a conveying roller 2, conveying augers 21 and a throwing fan 22. During work, the grain picking bent knife roller 11 rotates, teeth of grain picking bent knives 12 moving to the front end move cross the upper half portions of quinoa plants, as the harvester moves forward, the plants enter gaps between the teeth, grains on grain ears are threshed and fall into the conveying roller 2, the conveying augers 21 rotate, propelling blades of the conveying augers 21 push the grains to the end, where the throwing fan 22 is mounted, of the conveying roller 2, and the throwingfan 22 rotates together with the conveying augers 2 to form wind to throw the grains to a threshing device 3 of the harvester. The direct grain picking device for the quinoa harvester is simple in structure and high in working efficiency, crop stalks are not needed to be cut during work to facilitate subsequent recycling of the stalks, and good social benefits and economic benefits are achieved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a direct granulation device for a quinoa harvester. Background technique [0002] Quinoa is a whole-grain, nutritious and high-quality food recognized around the world. It is an alpine crop and its origin is mainly distributed in the Andes Mountains of the South American continent, such as Peru and Bolivia. In recent years, the planting area of ​​quinoa has continued to expand. More than 70 countries have planted quinoa, including the United States, Ecuador, Argentina, Canada and China. Among them, the total planting area of ​​my country has reached 2854 hectares, mainly distributed in Shanxi Province, In Jilin Province and Qinghai Province, the total planting area is still growing. [0003] In China, quinoa is mainly harvested manually, which is labor-intensive and low-efficiency. In some areas with large planting areas, full-feed grain harvesters have been mod...

Problems solved by technology

[0003] In China, quinoa is mainly harvested manually, which is labor-intensive and low-efficiency

In some areas with large planting areas, full-feed grain harvesters have been modified to harvest quinoa, but the modified models have problems such as incomplete threshing and uncleanness, which have brought great losses to growers
