Description
Technical field
The invention belongs to agricultural mechanical field, it is related to a kind of no-tillage seeding machine, more particularly, to a kind of anti-high stubble and thick straw
No-tillage seeding machine.
Background technology
Existing no-tillage seeding machine include frame and set gradually in frame fertilising trench digging cutaway disk, sowing and ditching
Disk and sowing disk earthing town, pinch roller seed-fertilizer box, feed mechanism for seed, drive system, monitoring system etc. composition；Product technology master
The developed countries such as Europe, the United States to be derived from, because their big absolutely farming areas are all the cultivation modes being harvested for one time each year, and their straw
The stalk response rate is very high, and when Second Year no-tillage seeding, the straw of earth's surface is all withered, rotten；And the most of area of China is one
Years two ripe, three ripe and the straw response rate is relatively low, will sow, the presence of substantial amounts of wet thickness straw, beyond existing after adding results
(grass pulling wheel diameter 310mm, radius only has 155mm, in addition the burying of fertilising ditching-disk and seed tray the careless function of dialling of product
Sink and the soil that takes up, reduce the effective working distance of grass pulling wheel) so disposable straw ground or after reclaiming after harvesting
High stub land, uneven stacking after ground straw haphazardly and crushed stalk, straw thickness (highly) is well beyond dialling
The scope (radius) of grass wheel and form congestion it is impossible to normal farming；Because the wet thickness of straw, ditching-disk can not completely cut through straw
Stalk, does not have the straw cutting off to be pressed into inside soil, seed is broadcast on straw, there is emerging jaundice or seedling thirst, withered etc.
Unfavorable condition, seeding quality seriously reduces.
Content of the invention
In order to solve above-mentioned technical problem present in background technology, the invention provides one kind can avoid congestion and can
The anti-high stubble of seeding quality and the no-tillage seeding machine of thick straw are effectively ensured.
The technical solution of the present invention is: the invention provides the no-tillage seeding machine of a kind of anti-high stubble and thick straw, bag
Fertilising trench digging cutaway disk support that including rack and the direction of advance along no-tillage seeding machine are successively set in frame and broadcasting
Plant support；It is provided with fertilising trench digging cutaway disk on described fertilising trench digging cutaway disk support；Along no-tillage on described sowing support
The direction of advance of seeder is disposed with sowing and ditching disk and sowing disk；It is characterized in that described anti-high stubble
And the no-tillage seeding machine of thick straw also include being arranged on fertilising trench digging cutaway disk support and with fertilising trench digging cutaway disk phase
Parallel anti-congestion device；Described anti-congestion device is included cutterhead and is connected with cutterhead and drives the driving that cutterhead rotates to fill
Put；Described cutterhead is paralleled with fertilising trench digging cutaway disk；The circumferencial direction of described cutterhead is provided with flail knife；Described driving means
Power resources in tractor motive power output shaft, speed changing box power output shaft or fertilising trench digging cutaway disk.
Above-mentioned cutterhead is 5～11 centimetres with the distance between the trench digging cutaway disk that applies fertilizer.
Above-mentioned flail knife is one or many；When described flail knife is many, described flail knife is uniformly arranged in the circumference side of cutterhead
To.
Above-mentioned flail knife is three.
Flail knife installing hole is provided with above-mentioned cutterhead, described flail knife is arranged in flail knife installing hole by bearing pin.
The circumferencial direction of above-mentioned cutterhead is also provided with cutter tooth；Described cutter tooth and flail knife are staggered.
The structure of above-mentioned cutter tooth is in involute shape.
The radius of gyration of above-mentioned cutter tooth is not more than 300mm；The radius of gyration in flail knife installing hole for the described flail knife is not more than
150mm.
The rotating speed of above-mentioned driving means is 100～500r/min.
The rotating speed of above-mentioned driving means is 200～400r/min.
The method have the advantages that:
The invention provides the no-tillage seeding machine of a kind of anti-high stubble and thick straw, 5 10 kilometers of equipment operating rate little
Constantly this no-tillage seeding machine passes through change speed gear box, the rotating speed speedup by fertilising trench digging cutaway disk be flail knife reach rotating speed 200～
400r/min, is 2---4 times of fertilising ditching-disk.Fertilising ditches cutaway disk while trench digging, on cutterhead and cutterhead
Flail knife with the rotating speed high-speed rotation of 200～400r/min, can be effectively by the straw of seeding belt, weeds under earth's surface and earth's surface
And root system of plant cut-out, under the centrifugal action of flail knife, after cutaway disk is advanced, dig the straw, miscellaneous below the soil coming
Grass etc. cuts off further, can also be cut off the increased surface covering not cut off further simultaneously, and the revolution at a high speed in cutter tooth
Lower straw, weeds, root system of plant are allocated to side, can go deep in soil, the root system of plant in cut-out soil, and by cutterhead
The straw etc. cutting off dialled from seeding belt, a cleaning kind bed by cutter tooth, it is to avoid the plough being contacted with soil is wound around by weeds etc., has
Improve seeding quality to effect.Second, because flail knife cutterhead is 3～11 centimetres of cutaway disk side position, on direct of travel with broadcast
Plant on one wire, just the straw on kind of bed, weeds, root system of plant etc. cleaned out, improve seeding quality, it is to avoid
The bad phenomenon such as withered Seedling, Seedling Huang.3rd, the power resources of driving means of the present invention can be dynamic by exporting after tractor
Power provides it is also possible to be provided by the no-tillage power sources such as land wheel output, prime mover of broadcasting, very convenient, is not subject to its structure or other dynamic
The impact of power output.
