Description
Technical field
The present invention relates to the field of plowing, specially a kind of ploughing apparatus using swing crushing soil block.
Background technology
Agricultural is one of the important component part of China's economy and the indispensable pillar of national economy.In agricultural,
Farm implements play very important effect.It can help peasant to improve farming efficiency, so as in limited farming area and time
In obtain more grain outputs.And in today of industry increasingly prosperity, agricultural tool becomes certainly from original livestock and manpower
Dynamicization degree higher, the modernization machinery of function more diversification.
But currently used for farming small-sized farm tools there are still it is many influence its effect the drawbacks of.Wherein, conventional small is ploughed
Ground machine can not effectively crush larger hardened soil block and can not freely adjust depth of plowing according to soil situation and need of work
The problem of spending is especially notable.Easily occur being difficult to broken relatively large clod on hardened soil, after plowing.This soil block
Crop budding, growth and the development of root system are not only interfered, can also largely influence soil pair during entire crop-planting
The absorption of fertilizer and moisture ultimately causes the underproduction of full wafer farmland, and further injury is generated to soil.In addition, for different
Soil situation, different crop species and different climatic environments, the depth of plowing needed are also not quite similar.
And small-sized equipment of plowing on the market cannot or be difficult generally to adjust depth of voluntarily plowing at present, can only pass through replacement
Machine adapts to different situations.Also, current equipment of plowing mostly is broken ground using plough tool or using rotary cutter to full wafer soil
Ground carries out directly broken.Wherein, although plough tool durability degree is not high, easily damaged and be easily worked, through often there is more large size after plough
Soil block remains；Although and can effectively crush soil block using rotating blade, blade is difficult to, and encounters stone, brick easily
Fracture is damaged.Therefore, it is badly in need of a kind of can effectively crush large size soil block and easily adjusting the small-sized of depth of plowing and plow
Machine.
