Description
Technical field
The present invention relates to agricultural mechanical field, more particularly to a kind of anti-blocking plough and using the no-tillage of the anti-blocking plough
Drill for sowing in lines.
Background technology
In conventional tillage, after turning over site preparation, plough is ditched in loose topsoil, sowed, and trench digging resistance is small,
The sharpness of cutting edge does not influence the advance resistance of plough significantly.But no-tillage stub land, earth's surface is solid and has substantial amounts of
Improving straw mulching, plough bury difficulty, and resistance is big, it is necessary to there is good breaking penetration performance, therefore till-less furrow opener is except having
Outside the performance of traditional plough, should also have sharp cutting edge, to reduce the advance resistance of plough, reduce the dynamic of tractor
Power consumes；Topsoil disturbance is small, and to reduce the soil mixing of soil levels dry and wet, creation is conducive to germination and root growth
Loose kind bed, improve sowing efficiency.
In wheat and corn two crops a year growing area, when implementing no-till maize, there is substantial amounts of wheat stalk powder on sowing ground
Broken returning to the field and untreated wheat root stubble, can produce seeder soil-engaging component winding and block, cause sowing machine operation
Poor quality, operating efficiency is low, generally requires and adds anti-block apparatus.Prevent that stalk winding is stifled on no-tillage seeding machine both at home and abroad at present
The method of plug soil-engaging component mainly has point stubble and cuts a batch two methods.Divide stubble method that crop straw stubble mainly is pushed away sowing
Band, such as divides sod lifter, point careless double-arc spline.These anti-block apparatus have certain blocking-proof result when straw mulching quantity is less, still
It is deteriorated in the larger time-division stubble positive effect of straw mulching quantity, anti-blocking performance is relatively low.The method of stubble is cut mainly by seeder soil
Crop straw stubble cut-out in front of workpiece, to prevent stalk from winding soil-engaging component.The method for cutting stubble is divided into passive type again
With active two types.Passive type cuts a batch component and power drive is not required, with the dragged rotation of machine advance.Passive type is cut
Stubble device is mainly made of various types of breaking disks.It is small that passive type breaking disc structure simply consumes power, but to straw
The cut-out energy force difference of stalk, and need machine to there is enough weight just stubble breaking knife breaking can be made to bury.An active batch component of cutting is
Carry out cutting a batch breaking under the driving of power.It is active cut batch device mainly have stip-chopping rotary cultivator attachment, driving breaking disk,
Stalk saw cutting device etc..
Notification number is that the utility model patent of CN 206602787U discloses a kind of no-tillage seeding machine having except root functionality
With anti-block apparatus, anti-block apparatus is arranged on no-tillage seeding machine and is arranged on the front side of plough；Anti-block apparatus include rack,
Cut stubble break ground device, except root device and drive transmission device；Cut the stubble device that breaks ground and be arranged on the front end of rack；Except root device is set
In the rear end of rack；Drive transmission device is installed in rack and is arranged on and cuts stubble and break ground device and except between root device, although
Have concurrently and cut stubble and break ground function and except root functionality, but when it cuts through batch, to consume power excessive, and soil and preceding stubble plant are destroyed
It is larger, it is not particularly suitable for protectiveness sowing.
The content of the invention
To overcome consumption power existing for seeder anti-block apparatus in the prior art excessive, broken to soil and preceding stubble plant
It is bad it is larger, be not particularly suitable for protectiveness sowing, the problems such as blocking-proof result is poor, the invention discloses a kind of anti-blocking plough, including preceding
The disc trench digging component and sowing and ditching component set afterwards, the sowing and ditching component include furrowing blade and spade, the spade

Compared with prior art, the beneficial effects of the invention are as follows：
(1) using two kinds of disc trench digging component and sowing and ditching component there is the component of function of ditching to combine to ditch,
Field is outputed by a certain seed furrow of width by disc trench digging component first, and by the preceding stubble plant roots among seed furrow
Bar is cut off, and realizes the preliminary trench digging before sowing so that sowing and ditching component is in water furrow planting, it is only necessary to digs a small amount of soil
Sowing can be achieved, reduce the trench digging difficulty of sowing and ditching component；Also due to before sowing and ditching component trench digging, first to front
Soil carried out primary ditching, the soil in ditch is translated into both sides to ditch, so ditch in sowing and ditching component
When, because the soil of trench digging is pushed to sowing and ditching components interior sowing and ditching components interior will not be caused to block；
(2) sowing and ditching component is ditched using furrowing blade, have it is small, easily with disc trench digging component collocation
Feature；And designed using furrowing blade, the soil of trench digging can be caused to assemble to sowing and ditching component rear, there is certain time soil
Effect；
(3) furrowing blade is made of furrowing blade main body and trench digging blade, and the lower face of the trench digging blade is less than the trench digging
Shovel main body lower face so that seed and fertilizer under sowing are unlikely to be walked by furrowing blade back body shovel；And by that will ditch
Blade guide portion width design is into less than trench digging portion maximum width so that the soil dug by trench digging blade can be in guide portion
There is the space of a buffering, easy to return soil；
(4) on the outside of two disks and inner side is fastened respectively using outer fastening assembly and interior fastening assembly, is greatly increased
There are fixing point and fixed-area between two disks, improve stability of the ditching-disk in trench digging；
(5) angle of flanging section and ditching-disk is adjusted by outer fastening plates adjusting part, ditching-disk can be controlled
The width of trench digging, controls the angle between the plane of two disks place.
