Straw smashing device

Abstract

The invention discloses a straw smashing device, and belongs to the technical field of straw treatment.The straw smashing device comprises a smashing box, two first rotating shafts are rotationally connected between the front wall and the rear wall of the smashing box, smashing rollers are fixedly connected to the outer walls of the first rotating shafts, and a conveying cylinder is fixedly connected to the right wall of the smashing box; the right wall of the smashing box and the left wall of the conveying cylinder are provided with communicated material returning openings, and the left wall of the smashing box is hinged to a filtering screen plate extending to the material returning openings. According to the scheme, smashed straw can be screened through the filtering sieve plate, the follow-up straw smashing effect and quality are improved, the straw which is not smashed completely above the filtering sieve plate can enter the conveying cylinder, the driving mechanism and the linkage mechanism are matched to drive the spiral conveying blade to rotate so that the straw can be conveyed upwards, and therefore the straw smashing effect is improved. And finally, the straw falls into the smashing box again to be smashed, complete smashing of the straw can be achieved, the situation that the straw which is completely smashed is doped in the finally-smashed straw is greatly avoided, and meanwhile subsequent livestock can eat the straw conveniently.

Description

technical field [0001] The invention relates to the technical field of straw processing, and more specifically, relates to a straw crushing device. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a multi-purpose renewable biological resource. Straw is also a kind of roughage, with high crude fiber content and lignin, which can be absorbed and utilized by cattle, sheep and other livestock. In the subsequent processing of the straw, it needs to be crushed, so as to facilitate the recycling, transportation and consumption of the straw. [0003] However, the current crushing equipment for str...

Problems solved by technology

[0003] However, the current crushing equipment for straw only simply crushes the straw, and the crushing of the straw is not thorough enough. The crushed straw material will still contain a lot of straw that has not been completely crushed. Not only the crushing effect of the straw is poor, but also the crushing The finished straw is not conducive to the subsequent processing, and there are more straws that are not completely crushed, which will cause livestock to be unable to eat or cause damage to themselves when eating, which cannot meet the demand
