Description

Comb-brushing air-suction type buckwheat combine harvesting device

Technical Field

The utility model belongs to the field of grain combined harvesting machinery, and particularly relates to a combing and air-suction type buckwheat combined harvesting device.

Background

Buckwheat is also called Umbe wheat, triangle wheat and Polygonaceae crops, belongs to one kind of pseudo cereal crops, is a food and medicine homologous crop integrating nutrition, health care and medicine, and is known as promising health food in the 21 st century. In recent years, with the increase of health consciousness and health care consciousness of people, the demand of buckwheat and its processed products in domestic and foreign markets is increasing year by year. Buckwheat has the biological characteristics that the maturity periods of seeds of the same plant are extremely different (the seeds at the lower part of the plant are mature, and the seeds at the upper part of the plant are in flowering and filling), and the seeds are extremely easy to fall off after the maturity. At present, the harvest of buckwheat is mainly divided into two-section harvest (i.e. cutting by a windrower to form a grain bed, airing for several days, and then completing the work of picking, threshing, cleaning and the like by a buckwheat combine harvester with a pickup) and combined harvest (completing the work of cutting, feeding, threshing, cleaning and the like at one time). Two-stage harvesting is the best harvesting mode at present, but the procedures are various, and the dropping loss of seeds is more easily caused by multiple links; in the long run, the combined harvest can reduce the seed loss rate due to the reduction of the times of planting, working links and the like, and becomes the most ideal and final harvest mode for buckwheat. However, most of the current buckwheat combined harvest references harvest machinery of large crops such as wheat and grains, and the like, and the harvest machinery comprises the steps of standing grain poking, cutting, feeding, threshing, cleaning and the like. Buckwheat is different from other crops, and due to the biological characteristics of buckwheat, when buckwheat and other crops are harvested in a combined mode, the moisture content of stalks is too high, so that a threshing roller is pulled and blocked; and mature seeds are easy to fall off from the stalks. Aiming at the situation, the utility model develops a combing and air-suction type buckwheat combine harvester.
