Description

Sunflower threshing device of sunflower combine harvester

Technical Field

The utility model relates to a sunflower harvester, in particular to a sunflower seed threshing device of a sunflower combine harvester.

Background

Sunflower is an important raw material for processing oil and food, and has become a main economic crop in rural areas in China. In recent years, the production of sunflower seeds has been on the rapid increase trend. Sunflower seeds are second only to peanuts, rapeseed, soybeans and cottonseed in eight-major oil plants, ranking the fifth place.

The sunflower seeds produced in China are mainly divided into two types, one type is the sunflower seeds specially used for extracting oil, the other type is the common sunflower seeds used for both eating and extracting oil, and the number of the common sunflower seeds is more at present. Various sunflowers in China are planted in cold and arid barren lands and saline-alkali lands in the north. At present, higher requirements are put forward by agricultural departments and commercial departments on mechanical seeding, field management, mechanical harvesting and other links of sunflowers. The mechanical harvesting requirement of edible sunflower is the most strict, such as the requirements of shortening the harvesting period, high harvesting efficiency, small harvesting loss, less kernel crushing, no scratch to the kernel epidermis, less kernel sorting impurities, collecting and reserving the sunflower discs as feed, chopping straws and returning the straws to the field and the like are provided. In particular, strict standards are established for commodity purchase of sunflower seeds, for example, peeled seeds are obtained when the peel falling area of the surface of the sunflower seeds reaches more than one third (including one third) of whole seeds, and the peeled seeds belong to unqualified products; the appearance quality is required to be consistent, the particles are complete and full, the cleaning is free from pollution, and the size and the shape are uniform.

However, only part of the areas currently adopt mechanized harvesting, mainly emphasizes the mechanized harvesting of the oil sunflower, and the mechanized harvesting of the edible sunflower is still in the development starting stage. Although there is edible sunflower harvester product production, the technology is not mature, and there are two main problems: firstly, harvesting in sections, namely harvesting the flower disc by a machine, then airing, and threshing by a manual or a threshing machine after seeds are dried. The disadvantages are that the harvest period is prolonged, a large amount of labor force for carrying and airing the flower disc is occupied, and the flower disc is often damped, mildewed and deteriorated due to improper storage in case of rain. Secondly, there is not special sunflower seeds thresher harvester harvesting machinery at present, mostly continue to use the harvester that is equipped with suitable wheat beans thresher, and line rod formula and spike-tooth formula threshing cylinder can not satisfy the requirement that the sunflower seeds thresh, and it has threshing unclean, and the sunflower seeds are easy broken, or make the sunflower seeds epidermis fish tail drop, have reduced the commodity rate of sunflower seeds product, cause these machines to be difficult to popularize and apply. Thus, threshing devices are the core component of combine harvesters, largely determining the threshing quality and productivity of the machine, and also having a large impact on separation cleaning. At present, a threshing device special for threshing sunflower seeds is urgently needed, the purposes of clean threshing, broken seeds and hidden injuries as little as possible, good separation performance, good universality and low power consumption are achieved. The sunflower discs after seed removal are kept complete, the breakage is reduced as much as possible, and the commodity rate is improved.
