Description

Coupling bionic straw-soil uniform mixed burying combined machine

Technical Field

The invention belongs to the technical field of agricultural machinery, and particularly relates to a coupling bionic straw-soil uniform mixed burying combined machine.

Background

The straw is a renewable organic resource which is extremely rich and can be directly utilized, and contains rich nutrients such as nitrogen, phosphorus, potassium fertilizer elements, organic matters and the like. The straw is returned to the field for treatment, so that the environmental pollution caused by the traditional straw burning can be prevented, and the problems of high transportation cost, difficult arrangement, safety, fire prevention and the like caused by the straw bundling and field separating process are avoided. Meanwhile, the organic matter of the soil can be supplemented, the physical and chemical properties of the soil can be improved, and the soil fertilizer has important promotion effects on the aspects of increasing the soil fertility, promoting the agricultural sustainable development, improving the agricultural ecological environment and the like. However, improper straw returning can be detrimental to crop growth and affect crop yield. Researches show that the more uniformly the straw and the soil are mixed, the more beneficial the metabolic activity of microorganism groups in the soil is to be improved, and thus the decomposition effect of the straw is improved. The higher the straw returning burying rate is, the less the quantity of the straws on the ground surface is, so that hosts of germs can be reduced, the survival rate of crop pests can be reduced, and the occurrence degree of crop diseases and insect pests in the next year can be reduced.

At present, most researches on relevant machines and tools for returning straws to fields pay attention to the crushing rate, soil breaking rate, field returning rate and the like of the returning straws, and the researches on the mixed burying uniformity of soil and straws are rare, so that the mixed burying uniformity of the machine and tools for returning straws to fields is poor, the distribution of the straws in a soil layer is uneven, the straw decomposition effect is poor, the nutrient release is slow, and meanwhile, the gaps caused by the uneven mixed burying of the straws can influence the emergence and growth of crops. In addition, the existing straw returning machine tool is still difficult to achieve the complete coverage of the straws, the decomposition effect of the straws remaining on the ground surface is poor, diseases and insect pests are easy to generate, and the machine tool is not beneficial to the field operation in the later period. Therefore, the development of the coupling bionic straw-soil uniform mixed burying combined machine is necessary.
