Description

A driving anti-blocking no-tillage and stubble breaking test platform

technical field

The utility model belongs to the field of agricultural machinery, and relates to a no-tillage planter, in particular, to a core working device of a no-tillage planter—a driving anti-blocking, no-tillage and stubble breaking test platform;

Background technique

The promotion of conservation tillage is an important measure for the sustainable development of agriculture in my country, and it is of great significance to the development of local economy, increase of farmers' income, and protection of ecological environment. One of the key technologies of conservation tillage is the no-tillage sowing technology, which is characterized by not plowing after harvesting, and directly using a special no-tillage seeder with stubble removal, fertilization, sowing, and soil covering mechanisms to sow on the stubble land; due to no-tillage The sowing equipment works on the surface with stubble left. The existing no-tillage equipment will have different degrees of clogging of ditching shovels and grass-soil mixing, and the bottom wet soil and surface dry soil will be stirred and mixed. When the seeds germinate, they cannot absorb enough water; not only increase the power consumption during sowing, but also have a great impact on the quality of sowing. Therefore, there is an urgent need to develop a no-tillage and stubble breaking mechanism, which can effectively solve the problems of ditching shovels entangled with grass, grass and soil mixing and dry and wet soil mixing during sowing;
