Straw cutting, crashing and sieving integrated device and method

Abstract

The invention discloses a straw cutting, crashing and sieving integrated device and a method and belongs to the technical field of agricultural machines. The straw cutting, crashing and sieving integrated device comprises a sieving chamber, a cutting and crashing chamber, a first cyclone separator, a second cyclone separator and a storage bin. According to the straw cutting, crashing and sieving integrated device provided by the invention, low-speed sieving is distinguished from high-speed cutting and crashing, and the sieving capacity of a material is enhanced due to the agitation effect of sieving blades, so that a thin material can be sufficiently sieved, and a coarse and short material can be returned back to the cutting and crashing chamber again for secondary crashing; and meanwhile, the crashing efficiency is improved. The straw cutting, crashing and sieving integrated device provided by the invention has the advantages of compact structure and small occupied area due to the integrated design of the sieving chamber and the cutting and crashing chamber. The straw cutting, crashing and sieving integrated device provided by the invention is applicable to straw resourceful treatment of small-size facility horticulture planting enterprises and individual farmers; the machining environment is improved; the labor intensity is reduced; the machining efficiency is improved; the production cost is reduced; and the high-efficiency production and the sustainable development of facility horticulture cleaning can be promoted.

Description

technical field [0001] The invention relates to a straw cutting, crushing and screening integrated equipment and process method, which is especially suitable for gardening straw cutting and crushing, and belongs to the technical field of agricultural machinery. Background technique [0002] Crop straw is the largest by-product of agricultural production in the world, and it is also an important biological resource that can be comprehensively utilized. With the development of agricultural production and rural energy, there is a large amount of surplus straw, and the problem of disposal of the remaining straw has become increasingly prominent. Especially in recent years, with the increasing development of protected horticulture, a large amount of horticultural straw and stubble mainly consisting of solanaceous fruits and melons will be produced every year. Most of the horticultural straws are tall cane straws, which are particularly difficult to crush. Because there is no spa...
