Description
Technical field
The present invention relates to agricultural machinery technological field, specially a kind of anti-wrap device of seeder.
Background technology
In China's wheat and paddy rice crop rotation area, preceding crop needs to carry out next round sowing in time after harvesting.Due to mechanization
Field plots is that wheat or rice straw are all covered after results, and seeder buries part grass easy to hang when working, winding, harmony it is stifled and
Frame kind.Seeder is by poor performance in the case of full improving straw mulching, and seeding quality is poor.
Traditional seeding method is to carry out Mechanization sowing after artificial crop straw burning again, and that what is caused during due to crop straw burning is big
Gas pollution has become severe the difficult problem of environmental protection.
Patent 201420237235 discloses a kind of seeder anti-winding device, is turned by the parabolic plate being arranged on main shaft
Movable property gives birth to blast, and the stalk after cutting is thrown to plough rear, then will by the finger group device rotation for being arranged on plough rear
Stalk is pulled out.But the effect for throwing stalk by the rotation of parabolic plate is limited, and refer to that dialling device needs to provide power active rotation, structure
Complexity, body and plough also occur that winding and stop up stifled during real work.
The content of the invention
The present invention is directed to the deficiencies in the prior art, there is provided a kind of anti-wrap device of the seeder of global design, especially fits
For the seeding machinery of full straw covering plot work.
The purpose of the present invention is realized by technical scheme below：
A kind of anti-wrap device of seeder, including seeder frame, main shaft, main shaft is provided with multiple knife groups, each knife

Frame aft is provided with countershaft, is connected by multigroup conveyer belt between main shaft and countershaft.
Further, conveyer belt is arranged between two adjacent groups knife group or between knife group and frame, and conveyer belt is that chain type is defeated
Send band or belt conveyor.
Further, belt outer surface is distributed with multiple spike-tooths, and spike-tooth is fixed by bolts on conveyer belt, or using nail
Tooth and the integrally formed conveyer belt with spike-tooth of conveyer belt.
Further, the horizontal plane angle that the axle center of main shaft is located with the plane residing for the axle center of countershaft and spindle axis is 0-
45°。
Further, main shaft rotates in the direction of the clock.
Further, plough is arranged between main shaft and countershaft.
Further, belt body direction is provided with dust excluding plate between the upper and lower layer belt body of conveyer belt, dust excluding plate is fixed on frame
On, it is parallel with lower floor belt body and in underlying band body surface, the front end of dust excluding plate is provided with scraper, and the edge of a knife of scraper is close to master
Axle.
Further, the both sides of knife group are evenly equipped with multipair cutting blade, and each pair cutting blade is symmetrically disposed in the both sides of knife group, move
One end of blade is fixed on the wall of knife group side, the other end extends in knife group outer circumferential side, and between each pair cutting blade gap is left.
Further, ledger-plate includes blade and base, and blade is vertically welded on base or is integrally formed with base, blade
Upside-down trapezoid is shaped as, cutting edge or front cutting edge are zigzag before and after blade, and base both sides leave elongated hole, can pass through bolt
It is fixed in frame；When knife group is rotated, ledger-plate is right through the gap between each pair cutting blade, and ledger-plate is monolateral with cutting blade
Gap is 1-5mm.
Further, cutting blade includes handle of a knife and cutter hub, and handle of a knife is rectangular scapus, and cutter hub is trapezoidal column, and handle of a knife and cutter hub are
Integrative-structure, with the left side of handle of a knife at grade, the thickness of cutter hub is more than the thickness of handle of a knife, handle of a knife to the upper bottom surface of cutter hub
Screw is provided with, bolt passes through screw being fixed on handle of a knife in knife group.
Compared with prior art, the present invention is realized by way of first cutting and dialling afterwards, when first knife group is rotated, cutting blade
Soil can be carried out it is micro- plough, while cutting blade is played without supporting shearing and choose role to the stalk in earth's surface, when provoking
Stalk enter in casing after, because the spacing of casing and cutting blade progressively reduces, preliminary extruding is completed to stalk, work as cutting blade
When moving to ledger-plate with stalk, the stalk moment to moving completes to support cutting.The cutting edge that ledger-plate is serrated can be with
Improve the cutting efficiency to stalk.The stalk for shredding falls on the conveyer belt of cutting blade both sides, then straight by the conveyer belt for moving
Connect and be delivered to sowing drive end unit, the spike-tooth on conveyer belt can also roll up the stalk being scattered between ground and conveyer belt when moving
Walk, the knife group for being sent to front with the conveyer belt for rotating clockwise is cut again, it is to avoid stalk drops between plough
Cause to wind and block.The setting of dust excluding plate can prevent the soil that knife group takes up when rotating from falling in belt inner surface, fixed
Scraper on dust excluding plate can wipe the soil being attached on main shaft off, prevent conveyer belt swollen disconnected.Working method is simple, greatly improves
Seeding machinery in full straw covering plot operation by performance and seeding quality, one-stop operation, can simultaneously complete multinomial agriculture
Skill index.Solve peasant's difficult problem that crop straw burning cannot not sowed, it is to avoid pollution during crop straw burning to air.Have simultaneously
Beneficial to straw-returning, the content of organic matter in soil is improved, reach cost efficiency, the purpose of good harvest of getting bumper crops.
