Description

Adjustable rotary tillage blade contour culture hillside fields tiller and using method
Technical field
The present invention relates to a kind of adjustable rotary tillage blade contour culture hillside fields tiller and using method.
Background technology
China is large agricultural country, and with the continuous development of agricultural cience and farming techniques, the agricultural production of plains region is realized substantially Mechanization.But China's totality landform is more complicated, a lot of agricultural production work have to carry out in Mountainous areas.By Very big in the ground line gradient of mountain and hill, agricultural production is carried out along gradient direction, water and soil is easily lost in, and people are along gradient side To work also than relatively hazardous, so typically taking the mode of the equal pitch contour agricultural production perpendicular to gradient direction in slope.Micro- Cultivated machine is in hillside fields contour culture(I.e. perpendicular to gradient direction farming)When, the biggest problem for facing is that machine can be because gradient mistake Turn on one's side greatly.Standard machinery is easily turned on one's side in slope equal pitch contour operation, it is impossible to normal operation, so the agricultural of hillside band is raw Produce and almost have not been achievable mechanization.By taking arable land as an example, existing arable slope land method is that original cattle is ploughed or excavated by manual work mostly, Not only inefficiency, and waste time and energy.The hillside fields tiller scheme that existing partial monopoly is proposed is using the high side of left and right wheels difference Formula adjusts fuselage to level, can prevent machine from turning on one's side, but due to installing left and right wheels height difference apparatus additional, fuselage quality greatly increases Plus, machine is difficult to transport to farming on mountain.
Content of the invention
It is an object of the invention to provide a kind of adjustable rotary tillage blade contour culture hillside fields tiller and using method.
