Description

Straw harvesting and crushing ditch deeply buried ploughing device

technical field

The invention relates to an agricultural machine, in particular to a straw harvesting, crushing and collecting ditch deeply buried ploughing device.

Background technique

At present, our country is facing the huge pressure of population increase and cultivated land sharp decrease. Therefore, improving the reasonable soil structure and soil fertility is one of the main ways to achieve high and stable crop yield and sustainable development. In the prior art, technologies such as ploughing with a share plough, deep ploughing with a chisel shovel, and rotary tillage are mainly used to plough the soil, and the straw on the surface of the soil is ploughed to the furrow of the previous ploughing of the share plough, The crop residues in the soil are tilled to the surface of the soil, thereby forming the plough layer structure of the soil. Although the above techniques have a certain effect on loosening the soil, these farming methods make it difficult to plough the straw on the soil surface neatly to the furrow of the previous ploughing of the plough. For example, when the straw is long, it may be put on hold. On the plough, it cannot be buried in the furrow, so that straw remains on the soil surface. At the same time, the crop residue in the soil cannot be effectively tilled to the furrow, and the crop residue and straw are often mixed in different plough layers. In the soil, the quality of tillage is low, the quality of land preparation after tillage is not good, and the soil ventilation and air leakage are serious, making it difficult for the soil to form suitable water, fertilizer, gas and heat conditions. The release of medium nutrients is slow; on the other hand, it makes it difficult for crop residues and straws to rot, and also inhibits the humification in the plough layer, which cannot preserve and accumulate organic matter, thereby greatly affecting the effect of straw fertilization and soil fertility; The loosening of the soil is prone to the insufficient contact between the roots of the crops and the soil, and the roots of the crops cannot be completely dissolved in the soil, resulting in low seedling emergence rate and slow growth. Crop yields decreased.

With the development of modern agriculture, straw has become a renewable resource, coupled with the steady increase in grain output, the output of straw has also increased significantly. Straw can be used as new energy development, feed or directly returned to the field, but the utilization rate of straw is currently low, most of which are directly discarded or incinerated, which not only wastes resources, but also causes more environmental pollution problems.
