Problems solved by technology

[0004] In the process of straw crushing, the straw is the stem and leaf of the dried crop, so it has a certain degree of toughness. When the feeding is too fast, the straw will easily block the cutter head of the crushing knife in the crushing box, and the rotating motor will be suffocated. Cause damage to the equipment, and the particle size of the crushed material cannot be guaranteed

Abstract

The invention discloses a straw crushing device, and belongs to the technical field of agricultural machinery. The device comprises a straw crushing box, an auxiliary feeding belt, feeding teeth, a feeding wheel, a pressing device, a segmented cutting device, a crushing motor, a rotary cutting knife and a discharging belt wheel. The feeding wheel is arranged in the middle of the straw crushing box, and the auxiliary feeding belt is arranged on the feeding wheel; and the plurality of feeding teeth are arranged on the surface of the auxiliary feeding belt, the pressing device used for pressing straw is arranged above the auxiliary feeding belt, the segmented cutting device used for chopping the straw is arranged below the pressing device, the crushing motor is arranged at the upper right corner of the straw crushing box, the rotary cutting knife is connected to the lower portion of the crushing motor, and the discharging belt wheel for discharging is arranged below the rotary cutting knife. Through the pressing device and the auxiliary feeding belt which are provided with a built-in gap, when the straw moves, the straw can be pressed and cut apart in a segmented manner, then the straw is conveyed into a material crushing cavity to be subjected to secondary refining and chopping, it is guaranteed that the straw cannot be blocked, and meanwhile the refining and crushing efficiencyis improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a straw crushing device. Background technique [0002] Straw is the general term for the stems and leaves of mature crops. It usually refers to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugar cane and other crops after harvesting seeds. With the development of agricultural production, China since the 1980s Since then, grain production has increased significantly, and the amount of straw has also increased. In addition, the promotion of firewood-saving and coal-saving technologies, the popularization of coal burning and the use of liquefied petroleum gas have resulted in a large amount of surplus straw in rural areas. Chinese farmers have a long history of using crop straw. It’s just that due to the low level of agricultural production, low output, and a small amount of straw in the past, except for a small amount of straw used for gaskets, feeding...
