Abstract

The invention relates to a machine capable of picking up straw, finely grinding the straw and throwing the straw to return to field. The machine comprises a picking up device (6), a conveying plate assembly (11), a grinding roll (10), a throwing accelerating roll (8) and a throwing guiding device (7) which are arranged from front to back sequentially between a left side plate and a right side plate of a housing (1), wherein a power output shaft (4) of a gearbox drives the picking up device (6), the conveying plate assembly (11), the grinding roll (10) and the throwing accelerating roll (8) towork through a drive device (5). The machine is reasonable in structure, economical and practical, can pick up, finely grind and throw the straw and has convenience in adjustment of throwing width andheight.

Description

technical field [0001] The invention relates to a machine for picking up, finely pulverizing, throwing and returning straw, belonging to the technical field of agricultural machinery. Background technique [0002] After the crops are harvested, a large amount of straw will be produced. If the crop straw is not treated, it will seriously affect the sowing operation of the next crop. The most common and convenient treatment methods are straw incineration and direct crushing and returning to the field. Because straw incineration not only wastes straw resources, but also causes serious environmental pollution and damages microorganisms in the soil. Directly crushing straw and returning it to the field by machinery is the main way of returning the straw to the field at present. Straw returning can effectively increase soil organic matter content, reduce soil bulk density, promote the production of large particle size aggregates in soil, improve soil fertility, promote the activ...
