A coupled bionic straw-soil uniform mixed operation machine

Abstract

A coupled bionic straw-soil uniform mixed-burying combined operating machine belongs to the technical field of agricultural machinery. The invention consists of a hooking device, a weeding device, a spraying device, a bionic rotary tillage device, a mixing device, a transmission covering device and a power transmission device. Composition, in which the weeding device cuts off the straw and sends it to both sides, and cleans the clean soil between the strips of straw; the spraying device sprays a decomposing agent on the straw to accelerate decomposition. The bionic rotary tiller throws the clean soil to the conveyor belt, and the mixing knife roller set avoids the problem of easy winding of the whole shaft. The resultant force of the relative rotation of the two mixing knife roller groups enhances the mixing effect and avoids uneven mixing from affecting the growth of crops. The distribution of the mixing knives ensures that the mixing is not missed. The conveying and covering device sends the clean soil to the mixture to complete the covering. , which is conducive to decomposition, avoiding straw residues affecting later operations and causing pests and diseases. The spraying, mixing and driving soil covering devices can be disassembled to complete strip tillage operations, and can also be adjusted to work in conjunction with the sowing and fertilizing devices.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a coupled bionic straw-soil uniform mixed burying joint operation machine. Background technique [0002] Straw is a kind of extremely abundant and renewable organic resources that can be directly utilized, containing rich nitrogen, phosphorus, potassium fertilizer and organic matter and other nutrients. Returning straw to the field can prevent environmental pollution caused by traditional straw incineration, and avoid problems such as high transportation costs, difficult placement, safety and fire prevention caused by straw bundling and leaving the field. At the same time, it can supplement 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 returning of straw to the...

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
