Description
Technical field
The present invention relates to a kind of zero-tillage anti-blocking ploughs, belong to plough technical field.
Background technique
With the development of modern agriculture, the limitation of conventional tillage technology is more prominent.Though such as traditional ploughing operation
It can so play the role of removing weeds, stubble within the regular hour, but long-term turning over can destroy ground vegetation to soil
Protection, aggravate soil erosion.Meanwhile rotary-tillage shredding soil can eliminate earthworm and biology in soil, lose soil slowly
Go due activity.As the number turned over increases, the vicious circle that soil is more easily accessible.At this time conservation tillage go out
It is existing, well solve this problem.No-tillage seeding technology refers to the multiple operation of trench digging, sowing, fertilising, application, earthing etc..
No-tillage seeding be mechanized farming by natural resources be converted into agricultural production and and an important factor for natural resources coordinated development it
One.How the anti-blocking performance of key equipment of the plough as conservation tillage, no-tillage seeding machine directly influences sowing effect,
Whether its performance reaches a standard and directly influences the popularization of protective farming technique.So the adaptability pair of Drill Opener of No-tillage Planter
It is significant to implement no-tillage seeding, development conservation tillage.
The U.S. starts to walk relatively early in terms of studying protective farming technique, and the type of product is also more, wherein being exempted from large-scale
It ploughs based on seeder, equipment is relatively mature, wherein with John Deere (John deer), Case (Keyes) for generation
Table.Canada and Australia no-tillage seeding machine on it is more be hoe shovel type ditching machine with dual, in pneumatic type drill for sowing in lines
On use it is the most universal.Uproot that shovel type ditching machine with dual light weight, structure are simple, ability of burying is strong, can while completing breaking into
Row trench digging；But work when be easier to wind weeds, in high speed operation, seed level is unstable, ditch it is wide make soil disturbance compared with
Greatly.Hoe shovel type ditching machine with dual has many advantages, such as light quality, structure is simple, it is easy to manufacture used on low speed grain dill compared with
It is more.But the wet soil of floor portions is translated into upper layer and dry ground mixing, and partial moisture loss is be easy to cause to be unfavorable for preserving soil moisture in this way,
It is unsuitable to apply to more arid area.
In recent years, bury ability and prevent blocking the problems such as row depth of China researcher mainly for no-tillage seeding machine
The research entered.It is the light weight of China's machinery, small in size compared with external no-tillage seeding machine.But equipment is small in size, causes structure tight
It gathers, thickness of sowing is big, thus the problems such as easily causing stalk, stubble blocking and passability to be limited.Currently, China is in no-tillage seeding machine
On using it is more be disk coulter and Sharp-angled opener.Disk coulter ditching depth is consistent substantially, is disturbed to soil
Move it is small, and have good passability.But biggish gravity is needed at work, it is small in size to be poorly suitable for China's light weight
Middle-size and small-size seeder.And sharp-angle type plough easily buries, and returns native better performances, therefore the middle-size and small-size no-tillage seeding in China is adopted substantially
With sharp-angle type plough.But there is also disadvantages for sharp-angle type plough, i.e., it needs bigger tractive force, especially exempt from hard
It ploughs in soil, structure will affect advance resistance.

Joint bearing seat 12, it is easy to connect reliable and stable.
Preferably, above-mentioned that multipair stubble-cutting mechanism, anti-block apparatus and ditching device are provided in rack 5, it can be realized more
Row trench digging improves trench digging efficiency.
Preferably, above-mentioned anti-block apparatus is arranged two, is arranged symmetrically in front of stubble-cutting mechanism two sides, so that stubble-cutting mechanism two
Side is balanced, improves service life and blocking-proof result.
Working principle: blade breaking plough is connect with no-tillage seeding machine rack, as the tractor of no-tillage seeding machine exists
When farm work, blade stubble remover outputs certain kind row while stub land breaking, and driving cutter disc groups are to blade stubble remover
Stubble not cut off and accumulating carries out secondary cut and makes its shunting, further realizes the anti-blocking of no-tillage seeding machine, double-arc spline
Obtuse angle plough is ditched in the kind row outputed, and the embedded depth of plough is 100mm or so, and operator at a distance of 50mm；
Its two sides is equipped with symmetrical wing fence, replaceable after wearing for convenience, and effect can increase the area of kind of bed, loose kind of row；Cutting
Weeds root system, and it is made to shunt unlikely heap to two sides, even if there is a small amount of stubble weeds to be attached in scalpel body, with dilatory
The continuous of machine moves ahead, and weeds slide into top by operator bar, then turns over a kind of stable state that remains that falls, structure is as schemed
Shown in 1.
When no-tillage seeding machine advances, the wheel shaft of walking ground wheel drives anti-blocking cutter shaft by chain conveyer, and anti-blocking blade is around cutter shaft
It circles, is in suspended state, when tractor advances, the weeds stalk on ground can be gathered in operator at leisure,
But anti-blocking blade can be rotated around anti-blocking cutter shaft, can thus be smashed stalk near plough and be thrown below.Meanwhile with
Tractor advance also can use anti-blocking blade cutting edge cutting tightly wind scalpel body weeds keep its fluffy, pass through knife
It is shunted when sword breaking plough to two sides.In this way, before anti-blocking blade can effectively clear up blade breaking plough
Some stalks and sundries, prevent workpiece from blocking.
The diameter of anti-blocking blade is designed according to the vertical range of ground and no-tillage seeding rack crossbeam, in the present invention
Consider that blade breaking plough generally buries 50-100mm at work, in order to can guarantee that complete machine can finally will with work well
The diameter of anti-blocking blade is determined as 300mm, with a thickness of 5mm.
Anti-blocking blade is mounted on anti-blocking cutter shaft, in the one root long steel pipe of center weld of anti-blocking blade, in long steel pipe
Screw hole is attacked in outer surface, is then arranged in one section of plane on cutter shaft, passes through screw hole with bolt and anti-blocking blade is fixed on cutter shaft,
Anti-blocking cutter shaft is driven by the wheel shaft that chain conveyer is connected to walking ground wheel, between blade breaking plough and anti-blocking blade
Concrete condition when horizontal distance can be according to field work is adjusted, and makes entirely to reach optimum Working.
The gravity for the entire equipment that double-arc spline obtuse angle plough leans on parallel link mechanism to connect at work will ditch
Two sides soil is squeezed in device sword wedging soil, forms kind of a ditch, double-arc spline obtuse angle plough is inclined relatively by two each other
Oblique plane disc composition, although penetrating angle is obtuse angle, but the contact due to two plane discs with soil be linearly can be with
Biggish stress is formed, therefore ability of burying is stronger.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Within protection scope of the present invention, therefore, protection scope of the present invention should be based on the protection scope of the described claims lid.
