Pull-type crop straw crushing device

Abstract

The invention discloses a pull-type crop straw crushing device. The device comprises an upper end protection device, arc-shaped filter screens, a fan assembly, a first conveying assembly, a screening assembly, a screening driving part, a bottom support, a material conveying part, a crushing assembly and a second conveying assembly, the bottom support comprises a supporting frame, and four wheels are arranged at the four corners of the lower end of the supporting frame; a material supporting table is arranged at the upper end of the supporting frame, the upper end protection device is arranged on the upper surface of the supporting frame, the crushing assembly and the two arc-shaped filter screens are arranged in the upper end protection device, and the crushing assembly is located above the right end of the material supporting table. A material scraping plate can be driven to move through a conveying chain, raw materials can be scraped to one side of the crushing assembly through the scraping plate, the pull-type crop straw crushing device is simple in structure, crushing can be conducted through double rollers, screening and conveying can be conducted after crushing, and convenience is provided for people.

Description

Technical field [0001] The present invention relates to the field of crop feed processing, and is specifically a traction crop straw pulverizer. Background technique [0002] Straw is the general title of the mature crop stem (ear). It is usually referred to as wheat, rice, corn, potatoes, rape, cotton, sugar cane and other crops (usually coarse grains) after harvesting seeds. More than half of the product used in crop light is present in straw, straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, is a multi-purpose renewable biological resource, straw is also a crude feed. It is characterized by high crude fiber content (30% -40%), and contains lignin. Lignin cellulose can not be used for pigs and chickens, but it can be absorbed and utilized by ruminant cattle, sheep and other livestock. With the development of agricultural economy, the number of crop straw is increasing, and traditional processing methods are in place, therefore causing seri...

Problems solved by technology

With the development of the agricultural economy, the amount of crop straws is increasing, and the traditional treatment method is local fire, which will cause serious environmental pollution and waste of resources, especially the burning of wheat straws will pollute the environment extremely seriously; Therefore, it is necessary to crush the straw so that the straw can be processed into feed, but the existing straw crushing device has a complex structure, poor crushing efficiency, and cannot screen the crushed raw materials, which cannot meet people's needs
