Meet the no-tillage seeding operation needs of the agronomic technique method, the existing research and development of no-tillage seeding machine, still, since implement structure designs
On deficiency, in no-tillage seeding operation to the key technology of former stubble breaking in terms of do not have breakthrough, breaking operation quality and effect
No-tillage seeding job requirements cannot be met, seeding operation is of poor quality, restricts and affect the advanced agronomic technique method of no-tillage seeding
Large scale application.
Invention content
The purpose of the invention is turned into industry aiming at the above-mentioned problems of the prior art, in conjunction with no-tillage seeding machinery
The demand used, a kind of no-tillage seeding machine of new construction of research and design, by using equipped serration type abnormity stubble remover assembly
Technical solution achievees the purpose that ensure and increases substantially former ridge breaking operation quality, meets no-tillage seeding job requirements.
What the purpose of the invention was realized in：No-tillage seeding machine includes support assembly, in the lower part of support assembly
On applicator boot assembly and seed opener assembly are installed successively from front to back, opened on the support assembly, positioned at fertilising
Serration type abnormity stubble remover assembly, the saw are installed in configuration at position between in front of ditch device assembly rear and seed opener assembly
Tooth-like abnormity stubble remover assembly includes link, peach-shaped cam sleeve, drive shaft, compression spring, shaft type idler wheel, axis pin, serration type
Special-shaped stubble breaking knife and drive sprocket, the peach-shaped cam sleeve are packed on link following side, and the rotatable inserting of drive shaft exists
On peach-shaped cam sleeve, axis pin is radially fixedly mounted in the drive shaft, pressure spring set fits on axis pin, serration type abnormity breaking
Knife is radially movable to be mounted on axis pin, the both ends of the surface of the compression spring respectively with drive shaft and serration type abnormity stubble breaking knife
Close contacting fit, shaft type idler wheel are mounted on serration type abnormity stubble breaking knife, the peach-shaped of the shaft type idler wheel and peach-shaped cam sleeve
Inner surface is in close contacting fit, and the cutting edge side of the serration type abnormity stubble breaking knife connects structure by sliding curve with jaggies
At the sliding curve is archimedes curve, and sawtooth crown line is Bezier；Link is connected with support assembly,
Drive sprocket is solid on the driving shaft, and the power drive system of no-tillage seeding machine is connect with drive sprocket.
The invention using serration type abnormity stubble remover assembly complete on former ridge there are crop root stubble and stalk
Successively carry out sawing and sliding cutting breaking farming, have breaking with disconnected straw effect is good, quality is high, operation is reliable, structure novel, conjunction
It manages, is simple, operating steadily, feature with small vibration, the large scale application for no-tillage agronomic technique provides technical support.

Specific implementation mode
The invention embodiment is described in detail below in conjunction with the accompanying drawings.A kind of no-tillage seeding machine includes that rack is total
At 1, applicator boot assembly 2 and seed opener assembly 4 are installed successively from front to back on the lower part of support assembly 1, in institute
It states on support assembly 1, configure and install at position between 4 front of 2 rear of applicator boot assembly and seed opener assembly
Serration type abnormity stubble remover assembly 3, the serration type abnormity stubble remover assembly 3 include link 5, peach-shaped cam sleeve 6, drive shaft
7, compression spring 8, shaft type idler wheel 9, axis pin 10, serration type abnormity stubble breaking knife 11 and drive sprocket 12, the peach-shaped cam sleeve 6 are solid
On 5 following side of link, 7 rotatable inserting of drive shaft is on peach-shaped cam sleeve 6, in the drive shaft 7 radially
Be fixedly mounted with axis pin 10,8 sets of compression spring fits on axis pin 10, serration type abnormity stubble breaking knife 11 it is radially movable be mounted on axis pin 10
On, the both ends of the surface of the compression spring 8 respectively with 11 close contacting fit of drive shaft 7 and serration type abnormity stubble breaking knife, shaft type rolling
Wheel 9 is mounted on serration type abnormity stubble breaking knife 11, and the peach-shaped inner surface of the shaft type idler wheel 9 and peach-shaped cam sleeve 6 is in closely to connect
