Description
Technical field
The present invention relates to a kind of farm machinery, particularly to a kind of with safety guard
Grain feed.
Background technology
Feed mechanism for seed is the critical component of seed-sowing machine, and hole roller is the core component of feed mechanism for seed, it
It is the most complicated in feed mechanism for seed and that cost is the highest parts with housing.At actual production operation process
In, occasional occurs having between discharging tube blocking, hole roller and seeder unit shell or limit kind plate
The hard objects such as stone, primary screw is blocked, feed shaft reversion or feed shaft collision rift bending
Problem, these problems can cause the instantaneous increase of the moment of torsion between hole roller and feed shaft, type hole
Wheel surface weares and teares, and seeder unit shell is damaged, greatly reduces the service life of feed mechanism for seed,
Delay farming season.
Summary of the invention
For technical problem present in prior art, it is an object of the invention to: one is provided
Being avoided that causes feed shaft, hole roller and seeder unit shell to damage in overload and feed shaft when inverting
The bad grain feed with safety guard.
The purpose of the present invention is achieved through the following technical solutions: a kind of with safety guard
Grain feed, including seeder unit shell, the type hole that is arranged on described seeder unit shell
Wheel and feed shaft, described hole roller offers driving hole, also includes the biography being arranged at hole roller
The safety guard being in transmission connection in dynamic hole and with feed shaft, described safety guard bag
Including body, spring and power shifting block, body is in transmission connection with feed shaft, and body is arranged
Blind hole, spring and power shifting block is had to be set in turn in blind hole；The hole wall epirelief of driving hole
Go out to have overload protection block, overload protection block to have power transmission face, the inner ring circle being sequentially connected
Cambered surface and inner ring fillet surface, described power shifting block acts against on power transmission face, inner ring
Arc surface and this mates.
Preferably, described power transmission face and power shifting block end face are inclined-plane.
Preferably, described bevel angle is 10 °-22 °.
Preferably, one end, inclined-plane of described power shifting block end face has and connects with driving hole hole wall
The curved surface touched, the other end has fillet surface.
Preferably, described overload protection block at least two.
Preferably, described overload protection block is distributed in driving hole, overload protection block, spring
And the quantity of power shifting block is identical and connects one to one.
Preferably, described overload protection block, spring and power shifting block are four.
Preferably, described safety guard is the most respectively by jump ring and feed shaft and type hole
Wheel connects.
Preferably, trepanning, described spring one end and blind hole are offered bottom described power shifting block
Connecting, the other end is connected with trepanning.
Preferably, described safety guard has boss, hole roller has and boss phase
The installing hole coordinated, boss matched in clearance is in installing hole.
The operation principle of the present invention: when discharging tube blocking, hole roller and seeding occurs in the present invention
The hard objects such as stone, primary screw is had to block or feed shaft collision between device housing or limit kind plate
During rear bending, cause moment of torsion on hole roller to increase, dial when the active force of moment of torsion acts on power
Time on block, if exceeding the frictional force of power shifting block outer circumference surface and blind hole inwall and overcoming bullet
When spring is to the jacking force of power shifting block, spring contraction, power shifting block departs from power transmission face,
And from inner ring arc surface slide to inner ring fillet surface slide to again the hole wall of driving hole again with power
Driving face contacts, if now moment of torsion is the most excessive on hole roller exceedes power shifting block outer circumference surface
With the frictional force of blind hole inwall and when overcoming spring to the jacking force of power shifting block, then power
Shifting block continues to depart from power transmission face skidding feed mechanism for seed and stops sowing, it is to avoid overload causes seeding
Axle, hole roller and seeder unit shell are damaged；When the feed shaft of feed mechanism for seed inverts, dynamic
Slide through inner ring arc surface and power transmission face along hole roller inner ring fillet surface in power shifting block top
Sliding to the hole wall of driving hole, if feed shaft still inverts, power shifting block top is protected in overload again
Protecting and skid on block, feed mechanism for seed stops sowing, it is to avoid use mistake to make feed shaft reversion cause row
Plant axle, hole roller and seeder unit shell to be damaged, reach the purpose of safeguard protection feed mechanism for seed.
Operator by later observing sowing situation or can install seeding monitoring warning system when finding not
During situation about sowing, shut down in time and fix a breakdown.
The present invention has such advantages as relative to prior art and effect:
1, the present invention be provided with safety guard be avoided that overload and feed shaft reversion time lead
Cause feed shaft, hole roller and seeder unit shell damage, and improve feed mechanism for seed service life, protect
Demonstrate,prove work efficiency.
2, one end, inclined-plane of power shifting block end face of the present invention has and contacts with driving hole hole wall
Curved surface, the other end has fillet surface.Curved surface is set and fillet surface can be avoided interfering, protect
Demonstrate,prove and can quickly stop sowing when overload or reversion.
3, power transmission face of the present invention and power shifting block end face are inclined-plane, and bevel angle is 10 °
-22 °, it is to avoid produce self-locking between two inclined-planes and affect safety guard and normally work.
