Description

Technical Field

[0001] The invention belongs to the technical field of biomass straw, and in particular relates to a biomass straw conveying and unpacking device. Background Art

[0002] Biomass refers to various organisms produced by plants through photosynthesis using the atmosphere, water, and land, including plants, animals, and microorganisms. In Northeast my country, especially in Heilongjiang, corn is grown on a large scale. However, due to the long-term influence of production and lifestyle, only 30% of the straw is used, and only 2.6% is processed and used. A considerable part of the straw is abandoned or burned, causing air pollution and waste of resources. The application of a large amount of straw is far from realizing the high-value conversion of straw, such as straw liquefaction and gasification to prepare chemical raw materials, straw power generation, straw biogas, etc. The main reason for this problem is the high cost of straw collection, storage, transportation, and pretreatment. Although straw balers have been used to directly bundle corn straw in the field, in order to prevent the straw bundles from falling apart, a layer of nylon mesh is wrapped around the bundled straw. The nylon mesh is a warp and weft interwoven together. Generally, the warp is relatively thick and the weft is relatively thin, which plays a role in helping the straw bundles not to fall apart. The straw bales are usually large and heavy, and the transportation and unbundling require a lot of manpower, which is inefficient and costly, thus limiting the conversion of straw into high value-added products. Therefore, it is of great significance to study a biomass straw transport and unbundling device. Summary of the invention
