Technical Field

The invention relates to the technical field of agricultural machinery, in particular to a straw crushing and recycling device for agricultural machinery.

Background

According to relevant statistics, as a big agricultural country, China can generate more than 7 hundred million tons of straws every year, and the straws become wastes which are not used much but need to be treated; the crop straw belongs to a very precious biomass energy resource in an agricultural ecological system; the comprehensive utilization of the crop straw resources has great significance for promoting the income increase of farmers, environmental protection, resource saving and sustainable development of agricultural economy; besides the traditional method of crushing and returning the straws to the field as organic fertilizer, new roads such as straw feed, straw vaporization, straw power generation, straw ethanol, straw building materials and the like are also provided, the utilization value and the utilization rate of the straws are greatly improved, and the method is worthy of reference; the method has the advantages that the method promotes the subsequent utilization of the straws, supports the industrialized development of new technologies such as straw wood replacement, fiber raw materials, clean pulping, biomass energy, commercial organic fertilizer and the like, perfects the matched industry and the development of downstream products, and extends the comprehensive utilization industrial chain of the straws; but the straws are light and large in volume, so that a large amount of manpower and material resources are needed for conveying the straws to each processing plant, the transportation cost is increased invisibly, the economic benefit of farmers is reduced, and the enthusiasm of the farmers for straw recovery is reduced; therefore, a straw crushing and recycling device for agricultural machinery is needed.

Disclosure of Invention
