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

Banded rotary tillage sowing machine is earthing method initiatively
Technical field
The present invention relates to farming technical field, relate in particular to a kind of initiatively earthing method 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, especially northern now, obtained popularization to a certain degree; and created certain economic benefit and social benefit, be one of effective way realizing agricultural sustainable development.And comparatively slow in the development in southern floods and droughts continuous cropping district, remove outside natural cause, lacking supporting with it no-tillage seeding machine is a very crucial reason.
At present, most of no-tillage seeding machine is to be all applicable to northern farming pattern, such as Chinese Patent Application No. is 200920175499.4, 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 sticky heavy soil and the higher rice root stub land operation of water content in south.When Rice in Southern China Mai Lianzuoqu carries out wheat cultivation operation, for create suitable kind bed to seed, the mode of normal application two subjobs reaches the requirement of soil lower thick upper thin, and Chinese Patent Application No. 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 No. 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 no-tillage seeding machine operation in trafficability characteristic, again can meet under the prerequisite that sowing requires, reduce under rotovator number of times and reduce energy consumption.For this reason, researching and developing a kind of sower active earthing technology that is suitable for southern heavy soil is very important.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is to provide a kind of adaptation in the banded rotary tillage sowing machine of southern heavy soil operation earthing method initiatively, its can meet under prerequisite that sowing requires, reduce under rotovator number of times and reduce energy consumption.
(2) technical scheme
For reaching above-mentioned purpose, the invention provides a kind of initiatively earthing method of banded rotary tillage sowing machine, it comprises the following steps:
Banded rotary blade is by the throwing backward of cut soil;
By separating twice assembly, collected, and by separating twice flail knife, it is further pulverized;
Soil after pulverizing flows in the kind ditch of being opened by banded rotary blade under the effect of contraction of soil guiding board, ordered cover institute's fertilise and sow on son; The block of not pulverizing is dished out outside machine under the effect of separating twice flail knife.
Preferably, the soil of pulverizing through separating twice flail knife enters soil guiding board after soil sieve screening.
Preferably, described soil guiding board is V-type soil guiding board, and V-type soil guiding board is gathered the soil sieving, and makes flowing of the directed fixed point of soil.
Preferably, by press wheel to covering fertilise and the soil sowed on son suppress.
(3) beneficial effect
The banded rotary tillage sowing machine active earthing method that the present invention adopts technique scheme to provide, when meeting southern heavy soil no-tillage farming, not only can once realize trench digging, fertilising and sowing, and by the effect of separating twice and screening, by soil layering in small, broken bits cover institute's fertilise and sow on son, the power consumption problem of bringing while reducing to pulverize soil under conventional rotovator secondary, has reduced operating cost.By banded rotary tillage sowing machine active earthing method, will further promote the further popularization of Rice in Southern China wheat continuous cropping district conservation tillage.
