Description

Agricultural production is with crops straw reducing mechanism

Technical Field

The invention relates to the field of agriculture, in particular to a crop straw smashing device for agricultural production.

Background

The straw is the general term of the stem and leaf (ear) part of the crop. Generally refers to the portion of wheat, rice, corn, oil, cotton, sugar cane and other crops that remains after harvesting the product (seed). More than half of the products of crop photosynthesis are used for the growth of stalks, and the stalks contain a large amount of crude fibers and rich nutrient elements such as nitrogen, phosphorus, potassium, calcium, magnesium and the like, so that the stalks are a renewable resource with multiple purposes, and the waste can be changed into valuable things by scientific and reasonable utilization. A large amount of crop straws are generated every year and are used as fuel for firewood or feed for cattle and sheep in the past, due to the improvement of life style change and farming technology, the crop straws become 'chicken ribs' which are tasteless and discarded, the natural degradation is difficult to be carried out in a short period (15-20 d) before sowing, carbon elements contained in the straws also obstruct the permeation of nitrogen (N) in soil, the growth of the next round of crops is not facilitated, farmers have to burn the straws on the spot, resources are wasted, the environment is polluted, and the feed becomes a social public nuisance. Experts think that burning straws mainly has the hazards of polluting air, destroying soil structures, influencing the surrounding environment and the like. In addition, the burning of the straw is also easy to cause fire and traffic accidents, and the burning of the straw can also cause greenhouse effect.

With the progress and development of science and technology, the straw utilization capacity of people is higher and higher, and the straw utilization capacity is mainly divided into two aspects, one is used as an industrial raw material, the other is used as a requirement for rural family life by burning, at present, a harvester can bundle straws when harvesting crops, the bundled straws are convenient to transport, and the space is saved, but the straw bundling machine is inconvenient to use as fuel in rural families, and for a small amount of straws in personal land, the straw bundling by adopting the bundling machine is very wasteful and inconvenient, so that a device for recovering straws for the rural families is necessary to be provided.
