Description

Vertical centrifugal oil sunflower threshing and cleaning device

technical field

The invention relates to the technical field of agricultural engineering, and relates to a vertical centrifugal oil sunflower threshing and cleaning device.

Background technique

Oil sunflower is the abbreviation of "oil sunflower". It is one of the four major oil crops in China. Native to the Americas, it is the second largest oil crop in the world. It was introduced to my country in the 15th century. It is one of the five major oil crops in my country and the third largest oil crop in Hebei Province. The oil extracted from the sunflower seeds of oil sunflower can be used to extract high-grade edible sunflower oil with low cholesterol. Because it contains about 66% "linoleic acid", it is known as the "healthy nutritional oil" in the 21st century, and is widely used in food, Medical and chemical fields. The grains are small, the husk is thin, the husk rate is between 20-30%, and the oil content is more than 45%. The seed coat is black, and the seeds are full; the resistance to pests and diseases is strong, and the seeds are mainly used for oil extraction. Oil sunflower has strong adaptability, high yield, up to 600 jin/mu, and output value of 500-1000 yuan; good oil quality; labor saving, fertilizer saving, water saving and low cost in the management process. The whole body of oil sunflower is a treasure, and the oil sunflower cake is also a good protein feed for livestock. After the sunflower plate is crushed, it is an excellent roughage for feeding pigs. The straw can be used to make fiberboard, paper, fuel, and pectin can also be extracted. Kwai pan is a good roughage for cattle and sheep, which needs to be collected and dried in the sun. The biomass of oil sunflower is large, the economic coefficient is about 20% to 25%, the potassium content in the stem and leaves accounts for 80% to 85% of the whole plant, and the phosphorus is about 40%, so the straw returning to the field is to return the nutrients of C, K and P elements. For effective measures to fertilize farmland, it is best to first use a disc harrow to chop the straw, apply chemical fertilizers and then plough. The oil sunflower stubble of straw returning is a good stubble, especially suitable for cotton planting.

The methods of manual threshing mainly include hand rubbing, stick percussion, stone rolling, etc., which are labor-intensive, low in production efficiency, and high in impurities. . Therefore, the oil sunflower threshing and cleaning machine is an important means to reduce the labor intensity and improve the production efficiency of oil sunflower. The difficulty of threshing mainly depends on the variety, maturity and humidity of the oil sunflower, which are closely related. At the same time, the main technical requirements for the threshing device are: clean threshing, and the crushing rate is as small as possible. my country is in the early stage of mechanization development of oil sunflower threshing and cleaning. The number of oil sunflower threshing and cleaning machines in the country is not high. The development of oil sunflower threshing and cleaning machines not only saves labor, but also improves productivity and economic benefits. Broad market and application prospects.

At present, some domestic enterprises and scientific research institutes have gradually developed oil sunflower threshing and cleaning equipment with a single function. And some companies have initial promotion. However, there are also problems such as low threshing rate, high loss rate, poor grain integrity and poor adaptability in production.

Although there are many types of oil sunflower threshing and cleaning devices, in order to improve the degree of mechanized harvesting of oil sunflower in my country, a simple structure, high threshing rate, low breaking rate and strong economic applicability are designed, which can effectively thresh and clean oil sunflower seeds. It is of great significance to improve the working efficiency of oil sunflower threshing and cleaning and to ensure the healthy development of the oil sunflower industry.
