The avoidance pattern of various different snow removing shovels, structural principle are broadly divided into following several patterns both at home and abroad at present:
Entirety lifts type, and using shovel body rear portion parallelogram sturcutre, under the impact force action by larger obstacle, snow cave shovel is whole
Body lifts surmount obstacles after using gravity Rapid reset.The pattern needs to lift entire snow cave shovel, and the impact force needed is also larger, whole
Body lifts the leakage left except area is big, and the adaptability of complicated road is poor.
Shovel body flip type has overall width overturning or local segmentation overturning, is generally used metal stretching spring as machine
Structure reset element, the pattern are mostly local avoidance movement, and it is relatively small that mechanism absorbs impact power；Metal spring performance degradation turns over
Rotation structure is larger, and reset function is often remarkably decreased in use for some time, influences the snow removing effect of snow cave shovel.
Edge of shovel part flip type, overturning avoidance structure is edge of shovel part, does not influence clear snow row's snow function of shovel body entirety,
It is also smaller to be segmented the impact force that avoidance is born；Snow cave shovel is needed to be integrated with a moment jump when being overturn by obstacle drag effect mechanism
Movement；Similarly, the edge of shovel need to overcome shovel body weight reversing reset, lesser structure under the action of metal compression springs after surmounting obstacles
The smaller reset function of spatial metal spring thrust is poor, generally requires operator and actively lifts shovel body so that the edge of shovel is in spring
It is resetted under the action of power.
The above avoidance pattern be generally used for overall weight is light, the biggish light-duty snow cave shovel in cutting angle in addition some in order to just
The edge of shovel perpendicular to road surface is taken in reset, therefore remove the snow poor snow throwing function, operating speed and efficiency is not also high.
Summary of the invention

The edge of shovel is joined with bolts with bracket, and the every edge of shovel such as excessive wear or shock damage can be replaced individually.
In clear snow operation, the edge of shovel advances at utmost speed along road surface, when shock of some edge of shovel by obstacle, is transmitted to high pressure
The active force of nitrogen gas spring reaches initiation value, and high pressure nitrogen spring is compressed rapidly, the corresponding parallelogram sturcutre of the edge of shovel
It backward and moves upwards, forms barrier avoiding function；The compression of gas absorbs impact energy caused by obstacle simultaneously.Do not have at this time
Encounter the normal clear snow of the edge of shovel of barrier.
After surmounting obstacles under the action of avoidance mechanism, external force is eliminated, the work of bracket and the edge of shovel in high pressure nitrogen spring
Restore original job position so that the edge of shovel being lifted up by avoidance falls with lower counter motion.
Under the action of shovel body support wheel, shovel body will not change relative to the relative position on road surface, and obstacle is encountered
Other edge of shovel that object is hit still keep original job state.The edge of shovel for generating avoidance movement is unrelated with shovel body height；Conversely,
In the reseting procedure after clearing the jumps, still unrelated with shovel body height, structure space meets movement needs.
Snow cave shovel obstacle avoidance apparatus of the present invention, in the edge of shovel by under normal Snow removing resistance, can holding mechanism stablize and realize just
Normal clear snow snow pushing operation.The big width obstacle such as similar road surface expansion joint is encountered, resistance reaches avoidance mechanism staring torque, can be real
Now whole avoidance movement surmounts obstacles.

When encountering bump partial barriers, resistance reaches avoidance mechanism staring torque, it can be achieved that the movement of single group avoidance surmounts obstacles.
Under job state, each obstacle avoidance apparatus can quickly reset after surmounting obstacles, and reset drives element uses elevated pressure nitrogen
Gas spring, can bear biggish obstacle resistance, and the speed of service of elastic element is higher stable.High pressure nitrogen spring can pass through
Adjustment the blowing pressure adapts to different operation resistance needs, and the performance that metal spring can also be overcome to be difficult to avoid that declines and is difficult to
The problem of reparation.
The movement of this obstacle avoidance apparatus avoidance is double rocking lever parallelogram mechanism, and snow cave shovel integrally has support wheel, operation process
Middle shovel board remains unchanged at a distance from road surface, and the movement of mechanism evacuation and homing action do not need lifting for shovel body, effectively improves
Avoidance sensitivity reduces the impact during avoidance.
This avoidance mechanism is that multiple groups are arranged side by side, and each group mechanism only needs to overcome itself double rocking lever individually or when integral reset
The resistance of parallel mechanism resets resistance little trick flexibility and reliability, does not also need the gravity for overcoming shovel body equally.
