Self-walking pneumatic transmission straw deep-burying machine

Abstract

The invention discloses a self-walking pneumatic transmission straw deep-burying machine. The machine includes a self-walking chassis, a rack, an engine, a transfer case, a front lifting device, a smashing and ditching drive device, a smashing and ditching device, a conveying device, a secondary smashing device, a storage box, a discharging pipe, a rear lifting device, a soil covering device, a compressing device and a control system. The smashing and ditching device and a draught fan are coaxially arranged on the rack to pick the straw for primary smashing, and two grooves for deep burying are formed. An outlet end of the draught fan is connected to a conveying pipe to convey the straw to the secondary smashing device for secondary smashing, smashed straw falls into the storage box, and the discharging pipe is arranged at the rear end of the storage box and used for introducing the straw into the grooves for deep burying. The machine can complete picking and smashing of the straw, ditching, conveying, secondary smashing, deep burying, soil covering and compressing at a time and has the advantages that the efficiency of collecting and smashing the straw is high, the effect of returning the decomposed straw into a field is great, and the adaptability to land conditions is high. Complete deep burying of the straw is achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a self-propelled pneumatic conveying straw deep burying machine. Background technique [0002] As the main by-product of agricultural production, straw is mainly used for feed, fuel, etc., only a quarter of the straw is returned to the field, and straw incineration causes both resource waste and environmental pollution. Straw returning to the field is an important agricultural management measure, which can increase the content of soil organic matter, loosen the soil, absorb more rainwater, preserve soil and fertilizer, and eliminate overwintering diseases and insect pests in shallow soil layers. At the same time, it can reduce farmland carbon Emissions and mitigation of environmental problems caused by straw burning. The existing straw returning machine only crushes the straw once. During the crushing operation, the high-speed rotating crushing knife c...

AI Technical Summary

Problems solved by technology

The existing straw returning machine only crushes the straw once. During the crushing operation, the high-speed rotating crushing knife cuts the straw. The structure is not completely destroyed, and it is not easy to decompose and become a base fertilizer, which will affect the seedling emergence rate in the next year

Existing straw returning machines, such as the air-flow strip straw collection and deep-burying machine whose application publication number is CN107820860A, are directly transported by wind to the deep-buried trench after the straw is crushed. The wind blows it to the outside of the trench, and the effect of returning to the field is poor

In addition, the existing straw returning machines are all traction or suspension types, and field operations and transfer transportation require the assistance of other machinery
