Straw crushing mixed buried covering machine with non-directional adjustable anti-blocking throwing device

Abstract

The invention belongs to the technical field of agricultural machinery and particularly relates to a straw smashing, mixed burying and mulching machine provided with a non-directional adjustable anti-blocking dispersion device. The straw smashing, mixed burying and mulching machine comprises a rack, a traction device (1), fixed cutters (2), a gearbox (3), a transmission assembly (4), the non-directional anti-blocking dispersion device (6), a soil breaking plate copying device (8), a soil breaking plate (9), a moving cutter smashing assembly (10), a dispersion amount adjusting device (11) and arotary tillage mixed burying assembly (12). The machine has the advantages that straw can be prevented from winding around guide plates, a working state is a non-directional dispersion state, and dispersion force is applied to the straw in a straw dispersion position, so that the straw moves for longer time in the air and is dispersed more unfirmly; the problems that pest and disease damage is easily caused by full-mulching treatment for straw returning to field and a seeding machine is blocked easily due to full-mixed burying treatment for straw returning to field are solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a straw crushing mixed burying machine with a non-directional, adjustable anti-blocking and throwing device. Background technique [0002] The amount of crop straw in our country is relatively large, and the straw contains rich nutrients. Straw returning to the field is a direct and effective use of straw. Straw returning to the field has the advantages of increasing soil organic matter, improving soil structure, preventing surface compaction, and reducing the use of chemical fertilizers. At present, there are two main returning methods of straw crushing and direct returning to the field: straw mulching returning to the field and straw mixed burying returning to the field. Straw mulching means directly covering the ground after the straw is crushed. The disadvantage is that it is easy to breed diseases and insect pests. The straw mixed burying means th...

Problems solved by technology

[0004] In view of the above technical problems, the purpose of the present invention is to provide a straw crushing and mixed mulching machine with a non-directional anti-blocking throwing device, which can not only prevent the straw from being entangled on the deflector, but also be a kind of non-directional throwing in the working state. In this state, a throwing force is applied to the straw at the straw throwing position, so that the straw moves in the air for a longer time, and the throwing is more uniform; it solves the problem that it is easy to breed diseases and insect pests when the straw is fully covered and returned to the field when the straw is fully buried and it is easy to block the planter. question
