Rice straw smashing device

Abstract

The invention belongs to the technical field of agriculture, and particularly relates to a rice straw smashing device. In order to solve the problem that winding is likely to happen, the rice straw smashing device comprises a lifting box and a smashing box, a mounting plate is horizontally welded to the upper portion of one side of the outer portion of the smashing box, and a first rotating motorand a vertical rod are vertically mounted on the two sides of the top of the mounting plate; an inclined column is installed at the top end of an output shaft of the first rotating motor, a moving rodpenetrates through the top of the vertical rod, a conical block is welded to the top end of the moving rod, the outer side of one end of the moving rod is sleeved with a spring, a cutter is installedat the other end of the moving rod, and a driving mechanism is arranged on the outer side of the smashing box; a partition plate is arranged below two smashing rollers, a rotating mechanism is arranged on the outer side of the smashing box, and a lifting machine is vertically mounted in a lifting box. According to the rice straw smashing device, rice straw can be cut off in advance before smashing, so that the situation that the rice straw is wound around the smashing rollers is avoided, secondary smashing is conducted on the straw, and smashing is more thorough.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a rice straw crushing device. Background technique [0002] Straw is the general term for the stems and leaves of mature crops, and usually refers to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugar cane and other crops after harvesting 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, etc. It is a multi-purpose renewable biological resource, and straw is also a roughage. Therefore, it is necessary to pulverize rice straw and put it into subsequent regeneration. [0003] The existing rice straw crushing device directly crushes the rice straw. Because the rice straw is relatively long and soft, it is easy to wrap around the crushing tool during the crushing process, resulting in poor crushing effect and reducing people's work effici...

Problems solved by technology

[0003] The existing rice straw crushing device directly crushes the rice straw. Because the rice straw is relatively long and soft, it is easy to wrap around the crushing tool during the crushing process, resulting in poor crushing effect and reducing people's work efficiency; The straw of the rice straw crushing device is only crushed once, and the crushing is not complete
