Anti-winding straw crushing device

Abstract

The invention provides an anti-winding straw crushing device. The anti-winding straw crushing device comprises a bottom plate; an enclosure is welded on the upper surface of the bottom plate; a crushing cavity is arranged in the enclosure; a feeding hole is welded at one side over the enclosure; the feeding hole is communicated with the crushing cavity; a crushing shaft is arranged in the crushingcavity; one end of the crushing shaft extends out of the enclosure, and is in transmission connection with a driving motor arranged on the bottom plate through a transmission wheel and a transmissionbelt; several crushing blades are fixed on the crushing shaft; several auxiliary cutters are fixed on the inner wall of the enclosure through a cutter frame; a base plate connected with the enclosureis at the bottom of the feeding hole through a screw assembly; several baffles are installed on the base plate; a discharging hole is arranged at the bottom of the crushing cavity; and a dischargingplate extending out of the enclosure is arranged below the discharging hole. According to the anti-winding straw crushing device in the invention, a movable cutter base is arranged; the movable cutterbase can horizontally move while rotating so as to drive the crushing blades to horizontally move; therefore, the crushing force of the crushing blades on straw structures can be increased; the ratethat the straw structures are wound on the crushing shaft is reduced; and thus, the anti-winding straw crushing device in the invention has good development prospect.

Description

technical field [0001] The invention relates to the field of straw recycling, in particular to a straw crushing device. Background technique [0002] Stem is the general term for the stem and leaf parts of mature crops. Usually refers to the remainder of wheat, rice, corn, potatoes, rape, cotton, sugar cane and other crops after the seeds are harvested. More than half of the products of crop photosynthesis exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. Chinese farmers have a long history of using crop straw, but due to the low level of agricultural production, low yield and small amount of straw in the past, most of the straw was used for fuel combustion, except a small amount was used for gaskets, livestock feeding, and part for composting. Lost. With the development of science and technology, the reuse of crop straw has become one of the very important modules, providing more possibilities for energy utilization....
