Description

Millet is little ridge membrane side multistage fine setting precision planter

Technical Field

The utility model belongs to agricultural machine seeding field especially relates to a hills mountain area arid mechanized millet little ridge membrane side multistage fine setting precision planter.

Background

The mountains and the west are big provinces of dry farming, dry land and moon in hilly and mountainous areas account for about 75% of the area of cultivated land, and nine drought and drought occur frequently in ten years. The small coarse cereals are planted and distributed in most of the Shanxi, and the millet is one of the main coarse cereal crops. In 1998 and 2012, the sowing area of the Shanxi millet accounts for 19.00-28.10% of the sowing area of the millet in China, and the production area of the millet is stabilized to be more than 300 ten thousand mu throughout the year. The mountainous and western millet is mainly concentrated in hilly and mountainous areas, is a predominant grain and economic crop in the hilly and mountainous areas, is difficult to plant in a large scale due to the requirements of continuous cropping planting and crop rotation, and is difficult to adapt to the actual requirements of hilly and mountainous areas, small land blocks, decentralization, small-scale production and dry land soil moisture-digging seeding in large-scale seeding machinery. The current hilly mountain area lacks small-size advanced suitable millet precision planter, except the drill barrow seeding of old people and animals power, traditional millet seeder mainly uses little four-wheel traction as the owner, the seed metering case borrows maize or wheat seed metering case to carry out the seed metering volume of linear regulation millet and is difficult to carry out precision control seed metering volume, also be difficult to carry out the fine control volume of sowing according to the quality of different millet varieties, grain size and seeding needs, be difficult to satisfy the light simple high-efficient demand of mechanized seeding of hilly mountain area millet production simultaneously, and hilly mountain area keeps having huge hand tractor and the machine of ploughing a little, it is idle because lack the millet precision seeding machine that can form a complete set. In addition, the spring drought and the drought in early spring sowing areas and middle and late spring sowing areas of Shanxi millet seriously restrict the normal sowing, seedling emergence and seedling protection of the millet and cannot ensure the normal production of the millet. Under the condition that the whole mechanized process in hilly and mountainous areas is increasingly accelerated and the major requirements of developing organic dry farming agriculture in Shanxi are met, the problems of adaptation to the land conditions of the hilly and mountainous areas, small farmers and small-scale production requirements, low price, suitability for large-scale dispersion and preservation, drought resistance, mechanized precision seeding and light and simplified production of small-sized advanced millet seeding machines and matched cultivation technologies need to be solved as soon as possible.
