As shown in Figure 1, being a kind of structural schematic diagram of duplicate rows self walking flax picking machine provided by the invention, including rack is walked certainly
1, which is characterized in that flax pulling mechanism, Shu Ma mechanism and noil mechanism are mounted on according to sequence from front to back from walking in rack 1,
Wherein, the structure of each mechanism is specific as follows:
Flax pulling mechanism includes duplicate rows hemp-plucking platform 21, oil cylinder 22 and flax pulling motor 23, and flax pulling motor 23 is mounted in duplicate rows hemp-plucking platform
On 21, and duplicate rows hemp-plucking platform 21 is driven by power distributor box 24,21 back side of duplicate rows hemp-plucking platform is connected to from walking in rack 1；Oil
Cylinder 22 is connected to be walked between rack 1 and duplicate rows hemp-plucking platform 21 certainly.Duplicate rows hemp-plucking platform 21 include left flax pulling mechanism, right flax pulling mechanism and
Flax pulling frame 211, left flax pulling mechanism and right flax pulling mechanism are symmetrically disposed on flax pulling frame 211.Left flax pulling mechanism and right flax pulling mechanism
On be provided with the middle and back that flax pulling driving wheel 212 is set to flax pulling frame 211 respectively, and power point is passed through by flax pulling motor 23
It is driven with case 24；Hemp-plucking wheel 213 is set to the front of flax pulling frame 211；Before flax pulling loosening and tightening wheel 214 is located at hemp-plucking wheel 213
Side and rear are installed on flax pulling adjusting rod 215, and flax pulling adjusting rod 215 is flexibly connected flax pulling loosening and tightening wheel 214；Flax pulling pinch roller
216 are set on flax pulling frame 211, between flax pulling driving wheel 212 and hemp-plucking wheel 213；Flax pulling rubber strip 217 connects flax pulling and drives
Driving wheel 212, flax pulling loosening and tightening wheel 214 and flax pulling pinch roller 216, and front end envelope is on hemp-plucking wheel 213；Overturning driving wheel 218 is set
It is placed on flax pulling frame 211, is located at 212 rear of flax pulling driving wheel, and driven by power distributor box 24 by flax pulling motor 23；Overturning
Loosening and tightening wheel 219 is flexibly connected flax pulling frame 211 by overturning elastic swing rod 2110, is located at 218 rear of driving wheel；Overturn pinch roller
2111 are set on flax pulling frame 211, are located at overturning 219 rear of loosening and tightening wheel；Reverse wheel 2112 is installed on the rear end of flax pulling frame 211；
The connection of rubber strip 2113 overturning driving wheel 218 and overturning loosening and tightening wheel 219 are overturn, overturning pinch roller 2111 is located at overturning rubber strip
2113 outsides.
As shown in figure 3, being a kind of structural schematic diagram of flax pulling mechanism provided by the invention.As shown, with left flax-picking machine
For structure, four flax pulling driving wheels 212 are symmetrically disposed on the middle and back of flax pulling frame 211 in pairs.Four hemp-plucking wheels 213 are two-by-two
One group of front for being symmetrically disposed on flax pulling frame 211.Flax pulling adjusting rod 215 is bending, and crooked place passes through shaft in pairs
It is movably connected on flax pulling frame 211, and half packet hemp-plucking wheel 213.There are two flax pulling loosening and tightening wheels for setting on each flax pulling adjusting rod 215
214, it is located at the front and back of hemp-plucking wheel 213.The tightness of flax pulling is adjusted in this structure, reduces flax pulling to waste of flax
Damage.Hemp-plucking wheel 213 is rubber wheel.Four flax pulling pinch rollers 216 are set in pairs on flax pulling frame 211, are located at flax pulling
Between driving wheel 212 and hemp-plucking wheel 213, flax pulling rubber strip 217 connects flax pulling driving wheel 212, flax pulling loosening and tightening wheel 214 and flax pulling pressure
Belt wheel 216, and front end envelope is on hemp-plucking wheel 213.Two overturning driving wheels 218 are set on flax pulling frame 211, are located at one
Group 212 rear of flax pulling driving wheel, and driven by flax pulling motor 23 by power distributor box 24.Two overturning loosening and tightening wheels 219 pass through
The respective elastic swing rod 2110 of overturning is flexibly connected flax pulling frame 211, is located at overturning 218 rear of driving wheel, overturns pinch roller 2111
It is set on flax pulling frame 211, is located at overturning 219 rear of loosening and tightening wheel.Two 2112 horizontal parallels of reverse wheel are installed on flax pulling frame 211
Rear end, overturning rubber strip 2113 connection overturning driving wheel 218 and overturning loosening and tightening wheel 219, overturning pinch roller 2111 be located at overturning
