Description
Technical field
The utility model is related to agricultural mechanical field more particularly to a kind of anti-blocking plough and using the anti-blocking plough
No tillage sowing drill.
Background technology
In conventional tillage, after turning over site preparation, plough is ditched in loose topsoil, is 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 a large amount of
Improving straw mulching, plough bury difficulty, and resistance is big, needs good breaking penetration performance, therefore till-less furrow opener is in addition to 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 mixing of soil levels dry and wet soil, creation is conducive to germination and root growth
Loose kind of bed, improve sowing efficiency.
In wheat and corn two crops a year growing area, when implementing no-till maize, there is a large amount of wheat stalk powder on sowing ground
Broken returning to the field and untreated wheat root stubble can generate 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 stalk winding 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 is mainly pushed away sowing
Band, such as divide sod lifter, point careless double-arc spline.These anti-block apparatus have certain blocking-proof result when straw mulching quantity is less, still
In the larger time-division stubble of straw mulching quantity variation with obvious effects, 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 as passive type
With active two types.Passive type cuts a batch component and does not need power drive, 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 machine is needed to have enough weight just stubble breaking knife breaking can be made to bury.An active batch component of cutting is
It carries out cutting a batch breaking under the driving of power.It is active cut batch device mainly and 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 in the front side of plough；Anti-block apparatus include rack,
Cut stubble break ground device, remove root device and drive transmission device；The stubble device that breaks ground is cut to be arranged in the front end of rack；Except root device is arranged
In the rear end of rack；Drive transmission device is mounted in rack and is arranged and breaks ground device and except between root device cutting stubble, although
It has both to cut stubble and break ground and function and removes root functionality, but consumption power is excessive when it cuts through batch, is destroyed to soil and preceding stubble plant
It is larger, it is not particularly suitable for protectiveness sowing.
Utility model content
To overcome consumption power existing for seeder anti-block apparatus in the prior art excessive, broken to soil and preceding stubble plant
The problems such as evil idea is larger, is not particularly suitable for protectiveness sows, blocking-proof result is poor, the utility model discloses a kind of anti-blocking plough, packets
