Abstract
The invention provides an active soil covering method of a strip rotary-tillage seeder. According to the method, a strip rotary blade throws cut soil backwards; the soil is collected by a secondary crushing assembly and further crushed by a secondary crushing flail knife; the crushed soil flows into seed ditches ditched by the strip rotary blade under the constraint action of a soil guide plate, and orderly covers applied fertilizers and sown seeds; and straws, root stubbles and soil rafts which are not crushed are thrown out of the seeder under the action of the secondary crushing flail knife. According to the invention, while the no-tillage operation of southern heavy soil is satisfied, operations of ditching, fertilization and seeding can be realized at one time, and under the action of secondary crushing and screening, fine soil is hierarchically covered on applied fertilizers and sown seeds, so that the problem of power consumption caused when a conventional rotary cultivator goes to the fields and carries out soil crushing is reduced, and the operation cost is lowered.
Description
Technical field
The present invention relates to the farming technical field, relate in particular to initiatively earthing method of a kind of banded rotary tillage sowing machine.
Background technology
Conservation tillage has the aspect effects such as water conservation, soil conservation, fertilizer conservation and cost-saving synergistic; China is especially northern now, has obtained popularization to a certain degree; and created certain economic benefit and social benefit, be one of effective way that realizes agricultural sustainable development.And comparatively slow in the development in southern floods and droughts continuous cropping district, remove outside the natural cause, lacking supporting with it no-tillage seeding machine is a very crucial reason.
At present, most of no-tillage seeding machine all is the farming pattern that is applicable to the north, number be 200920175499.4 such as Chinese patent application, name is called the utility model patent of " wheat no-tillage planter ", introduce the correlation technique of cutting the broken grass of stubble, but be not suitable with sticking heavy soil and the higher rice root stub land operation of water content in south.When Rice in Southern China Mai Lianzuoqu carries out the wheat cultivation operation, for creating suitable kind bed to seed, the normal mode of using two subjobs reaches thick thin requirement under the soil, and Chinese patent application number is 201010621604.x, name is called the application for a patent for invention of " free-planting seeder for wheat in rice stubble field ", " Y " type of utilization blade has solved the attachment issue of stalk and weeds, Chinese patent application number is 201020172416.9, name is called the utility model patent of " the trench digging stubble-cleaning integrated mechanism of rice stubble field non-ploughing wheat zero tillage combined seed ", focus on solving the problem of trench digging and stubble-cleaning, but all not mentioned how when guaranteeing the no-tillage seeding machine operation in the trafficability characteristic, again can satisfy reduce under the prerequisite that sowing requires under the rotovator number of times and reduce energy consumption.For this reason, a kind of sower active earthing technology that is suitable for southern heavy soil of research and development is very important.
Summary of the invention
The technical problem that (one) will solve
