Abstract

The invention discloses a straw chopping device, which comprises a frame, wherein the upper end of the frame is movably connected with a conveying base, a fixing chopping table is arranged on the frame, a crankshaft is movably connected below the fixing chopping table, the crankshaft is connected with the conveying base through a base connecting rod, a guide rod is respectively fixed on the uppertop surface of the fixing chopping table close to the end parts of two ends of the fixing chopping table in the vertical direction, guide blocks movably sleeves on the guide rod, a chopping knife is fixedly connected between the two guide blocks, a pressure head is connected below the chopping knife through a spring, a pressing port is formed between the pressure head and the fixing chopping table, a lower chopping knife is connected with the top surface of the fixing chopping table; the lower chopping knife is matched with the cutting knife to cut straw, the two ends of the crankshaft are respectively connected with the guide blocks on the corresponding sides through cutting connecting rods. According to the invention, the straw can be thoroughly chopped, and the problem that the conventional chopping device or crushing device cannot chop or even wind a shaft or cut a knife because the straw is soft is thoroughly solved.

Description

technical field [0001] The invention relates to the technical field of straw crushing equipment, in particular to a straw chopping device. Background technique [0002] my country is a large agricultural country, which produces about 600 million tons of crop straw every year. The traditional straw disposal method is to burn the straw on the spot, causing serious pollution to the environment. [0003] Crop reprocessing is an important method to realize the reuse of resources and turn waste into treasure. The shredder can chop and crush the whole straw crops into certain specifications and shapes, so that they can be used as forage grass and fuel for burning power generation. Crushing and processing crop straws through pulverizers, and fully recycling them, not only greatly reduces the waste and burning of straws, reduces environmental pollution, but also improves air quality; moreover, the crushed straws have higher utilization value, such as Crushed feed can retain more co...
