Description

A self-excited vibration subsoiling and soil preparation combined operation machine for mountainous areas

technical field

The utility model relates to the technical field of agricultural machinery, in particular to a mountainous self-excited vibration, subsoiling, land preparation and suppression combined operation machine.

Background technique

my country is a mountainous country, with mountainous areas (including hills and plateaus) accounting for 66% of the total area, and mountainous arable land accounting for 46% of the total arable land area. One-third of the country's grain is produced in mountainous areas. Slopes and horizontal terraces in hilly and mountainous areas mainly rely on rainfall to solve the problem of water use in the process of crop growth, which requires strong water storage capacity in farmland. The traditional method of farmers is to increase the amount of rainwater storage by plowing and deepening the plowing layer, but the problem that comes with it is that plowing will loosen the topsoil of the farmland. Cause wind and sand to raise dust. With the promotion of no-tillage conservation tillage, the area of plowing operation has been greatly reduced, and the task of increasing soil water storage capacity can only be completed by subsoiling. Subsoiling is a conservation tillage method that uses the subsoiler's subsoiler to loosen the soil deeply and deepen the plow layer without turning the soil, which is summarized on the basis of traditional plowing. It is suitable for dry farming agriculture. Through deep loosening, the farmland breaks the plow bottom layer formed by traditional farming machinery, thus forming a deep virtual and solid soil layer structure. This structure is conducive to water storage and moisture conservation, and promotes the exchange of water, fertilizer, air and heat in the soil, and promotes The growth of crops ensures the stable and increased yield of crops.

It is an effective way to reduce the cost of agricultural production and reduce soil compaction by implementing joint operations and reducing the number of times machinery enters the field.
