Description
Technical field
The invention belongs to agricultural machinery, relates generally to a kind of bar of the gear eight original position feeler mechanism of seeder adapted.
Background technology
Traditional seeder is the uniformity for ensureing depth of planting, to ensure the uniformity emerged and the plant growth of seed
Neat row, feeler mechanism is equipped with, for drill for sowing in lines frequently with single hinge feeler mechanism, and general for imtertilled crop using flat
The bar feeler mechanism of row four；But two class feeler mechanisms there is a problem of certain, the profiling of single hinge is opened in floating copying operation process
The penetrating angle of ditch device can change, cause acute angle plough bury clearance angle change and occur plough blocking situation, and
During parallel link mechanism operation, although ensure that plough does plane motion, and plough angle of penetration is constant, but trench digging
The lengthwise position of device can change with the fluctuating of gauge wheel, all can produce certain shadow to the profiling operation of plough
Ring, so that influence crop emerges, therefore, neither there is angle change, and do not indulge in profiling operation process in research one kind
There is important practical significance to the seeder Special copying mechanism of displacement.
The content of the invention
A kind of problem that the purpose of the invention exists aiming at above-mentioned prior art, bar of gear eight of research and design is former
Position feeler mechanism, realizes with the advance of seeder, the floating copying operation with the lifting of gauge wheel of floating frame, and protect
Card floating frame is done and only does translation, does not there is rotation, ensures that floating frame is relatively fixed the position that frame does not occur on fore-and-aft direction again
Move.
What the purpose of the invention was realized in：Equidistantly be fixedly mounted with upper pin in fixed frame sided linear, it is described on
Rotatably assemble intermeshing gear arm of going forward, upper transition gear, upper back tooth wheel arm on bearing pin successively from front to back；It is described solid
Front portion is fixedly mounted with limited block under determining frame side, and the limited block is located at below gear arm of going forward；It is described go forward gear arm and on
Backgear arm lower end respectively by nipper wheel arm and lower back tooth wheel arm under preceding bearing pin and rear pin shaft rolling assembling, the preceding bearing pin with
Rear pin shaft is connected by extension spring；Lower bearing pin is equidistantly fixedly mounted with floating frame sided linear, successively may be used from front to back on the lower bearing pin
The intermeshing lower nipper wheel arm of rolling assembling, lower transition gear, lower back tooth wheel arm；Fixed frame and floating frame both sides are all
Part is arranged symmetrically, and so far constitutes the bar of gear eight original position feeler mechanism.
The invention by using bearing pin be connected on frame and floating engine by transition gear it is intermeshing it is upper,
Lower tooth wheel arm, when floating frame profiling operation, the front and rear teeth wheel arm with the identical number of teeth and modulus by two have etc. tooth
Number, the engagement of the transition gear of modulus, make front and rear teeth wheel arm realize with equal angular and turn to opposite gyration, real
The extension spring showed between the movement that floating frame is relatively fixed frame vertical direction, forward and backward bearing pin gives floating frame by gear arm
Downward effect, meanwhile, the limited block on fixed frame limits the rotate counterclockwise of gear arm of going forward, i.e., floating engine is erected
The effect of lower limit is arrived.Meanwhile, the utensil has novel, simple, reasonable, easy to operate structure, reliable in quality, applicability wide
Feature.

Specific embodiment
The embodiment to the invention is described in detail below in conjunction with the accompanying drawings：
A kind of bar of gear eight original position feeler mechanism, upper pin 2, the upper pin are equidistantly fixedly mounted with the sided linear of fixed frame 1
Rotatably assemble intermeshing gear arm 4 of going forward, upper transition gear 3, upper back tooth wheel arm 14 on axle 2 successively from front to back；Institute
Front portion is fixedly mounted with limited block 5 under stating the side of fixed frame 1, and the limited block 5 is located at below gear arm 4 of going forward；The upper nipper
Wheel arm 4 and the lower end of upper back tooth wheel arm 14 are respectively by nipper wheel arm 8 and lower back tooth wheel under preceding bearing pin 7 and the rolling assembling of rear pin shaft 13
Arm 12, the preceding bearing pin 7 is connected with rear pin shaft 13 by extension spring 6；Lower bearing pin 9, institute are equidistantly fixedly mounted with the sided linear of floating frame 10
State and rotatably assemble intermeshing lower nipper wheel arm 8, lower transition gear 11, lower back tooth wheel on lower bearing pin 9 successively from front to back
Arm 12；The all parts of fixed frame 1 and the both sides of floating frame 10 are arranged symmetrically.
During operation, the feeler mechanism advances with seeder, when floating frame 10 rises with gauge wheel, rolling assembling
The lower rotate counterclockwise of nipper wheel arm 8 on the side lower bearing pin 9 of floating frame 10, it is logical with it because of the numbers of teeth such as all gears, modulus
Cross the lower back tooth wheel arm 12 that two lower transition gears 11 are meshed angularly to turn clockwise, now, because upper and lower gear arm passes through
Bearing pin is connected, and goes forward have identical gear drive meshing relation between gear arm 4 and upper back tooth wheel arm 14, therefore, both etc.
Angle rotates backward, and because all gear arm radius of gyration are equal, therefore all gear arm corners are identical, therefore, floating frame 10 is real
Plane that it is relatively fixed frame 1 linear motion is straight up showed, now, the distance between preceding bearing pin 7 and rear pin shaft 13 increases
Greatly, extension spring 6 is elongated, and its pulling force is reacted in floating frame 10 by lower tooth wheel arm, and downward effect is produced to it, and the moment protects
Demonstrate,prove and angle does not occur between contact of the gauge wheel being fixedly mounted with floating frame 10 with ground, i.e. floating frame 10 and fixed frame 1
Change, ensures the constant of fore-and-aft direction displacement between the two again, conversely, when floating frame 10 declines, all components have opposite
Motion state, meanwhile, the limited block 5 on fixed frame 1 limits the rotate counterclockwise of gear arm 4 of going forward, i.e., to floating engine
Frame 10 serves the effect of lower limit.
