Abstract

The invention relates to a multistage straw fine crushing and dispersing field returning device and belongs to the technical field of agricultural machinery. The multistage straw fine crushing and dispersing field returning device comprises a housing (1) and a gearbox (3), wherein the housing (1) comprises an upper cutter distance adjusting groove (1141), a lower cutter distance adjusting groove (1142), a hydraulic rod support rod (115), a dispersing accelerating device mounting hole (117), a dispersing adjusting device mounting hole (1142), a cutter distance adjusting device (6), a hydraulicrod (7), a cutter distance adjusting device support rod (8), a straight-cutter crushing device (10), a dispersing accelerating device (11) and a picking crushing device (12). The multistage straw fine crushing and dispersing field returning device has the advantages that the fixed cutter of a traditional crushing field returning machine is changed into a rotary straight cutter, so that energy-saving straw cutting is achieved; by a hydraulic device, the distance between a 'Y'-shaped crushing cutter and the straight cutter can be adjusted in real time according to the straw distribution conditions in a field, a better straw crushing effect is achieved, and the probability that the device is blocked by the straw can be lowered at the same time.

Description

technical field [0001] The invention relates to a device for picking up straw, finely pulverizing it, throwing it and returning it to the field, and belongs to the technical field of agricultural machinery. Background technique [0002] At present, the traditional corn stalk returning machine uses a high-speed rotating crushing knife to crush the stalks. Due to the randomness of the distribution of straw on the ground surface, the traditional straw crushing and returning machine has problems such as different lengths of straw crushing, low uniformity of throwing coverage, and difficulty in adjusting the throwing width during the crushing operation. These problems will seriously affect the sowing operation of the next crop. Contents of the invention [0003] In view of the above technical problems, the purpose of the present invention is to provide a straw multi-stage fine crushing throwing and returning device, which can realize multi-stage straw crushing, uniform throwin...
