Coupling bionic straw-soil uniform mixed burying combined machine

Abstract

The invention relates to a coupling bionic straw-soil uniform mixed burying combined machine, and belongs to the technical field of agricultural machinery. The coupling bionic straw-soil uniform mixedburying combined machine consists of a hanging connection device, a grass pulling device, a spray application device, a bionic rotary tillage device, a mixing and stirring device, a transmission soilcovering device and a power transmission device, wherein straws are cut off and pulled and conveyed to the two sides by the grass pulling device; clean soil is cleaned out among straws in stripped distribution; and the spray application device sprays and applies decomposition agents to the straws to accelerate decomposition. The bionic rotary tillage device throws the clean soil to a conveying belt; and through mixing and stirring cutter roller groups, the problem of easy winding caused by use of whole shafts is avoided. The mixing and stirring effect is enhanced through resultant force of relative rotation of the two mixing and stirring cutter roller groups. The influence on the growth of crops due to nonuniform mixing and stirring is avoided. Through the distribution characteristics ofthe mixing and stirring cutters, no missing of the mixing and stirring is realized; through the conveying soil covering device, the clean soil is conveyed onto mixed and stirred materials to completecovering and burying; decomposition is facilitated; influence caused by straw residues on later-period operation and occurrence of plant diseases and insect pests are avoided; and the spray application device, the mixing and stirring device and the transmission soil covering device can be dismounted to complete strip cultivation operation, and can also be regulated to realize combined operation with a seeding and fertilizing device.

Description

Technical field [0001] The invention belongs to the technical field of agricultural machinery, and specifically relates to a coupled bionic straw-soil uniformly mixed and buried combined operation machine. Background technique [0002] Straw is a kind of extremely rich and renewable organic resources that can be used directly. It is rich in nutrients such as nitrogen, phosphorus, potassium fertilizer and organic matter. Returning straw to the field can prevent environmental pollution caused by traditional straw burning, and avoid the problems of high transportation cost, difficult placement, and safety and fire prevention during the process of baling and leaving the field. At the same time, it can replenish soil organic matter, improve soil physical and chemical properties, and play an important role in increasing soil fertility, promoting sustainable agricultural development and improving agricultural ecological environment. However, improper return of straw to the field will a...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the research on straw returning machines and tools focuses on the crushing rate, crushed soil rate, and returning rate of straw returning to the field. There are few studies on the uniformity of soil and straw mixed burial, resulting in uneven mixed burying uniformity of straw returning machines. Good, uneven distribution of straw in the soil layer leads to poor straw decomposition effect and slow nutrient release. At the same time, the gaps caused by uneven straw burying will affect the emergence and growth of crops

In addition, the current straw returning machines are still difficult to achieve complete coverage of straw, and the residual straw on the surface is poorly decomposed, prone to pests and diseases, and is not conducive to later field operations
