Description
Technical field
The invention belongs to snow removing equipment technical fields, and in particular to a kind of Semi-automatic small snow breaker.
Background technique
To ensure, vehicles and pedestrians are smooth on road surface when winter snows, and need the accumulated snow removal on road surface.In city
On city's road or more road of great width, it can be removed the snow using earth mover, snow removing effect is good and high-efficient；Comparing
On narrow road, on township road, village road and hill path, large size snow removing equipment can not carry out operation, can only rely on artificial snow removing,
But artificial efficiency of cleaning snow is lower, and labor intensive is very high, and the effect to remove the snow is bad.It is existing for these disadvantages manually to remove the snow
Technology discloses part small-sized snow-removing equipment, can be used in the small road of limited width, but these small-sized snow-removing equipment are all
Directly snow to be pushed open with push plate, the snow being open is constantly accumulative in the side of push plate, when reaching certain thickness, the snow meeting that is open
Push plate is not crossed, continues to stay on road surface, causes snow removing effect bad.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of Semi-automatic small snow breaker, by pressing plate by accumulated snow pressure
It is real, reduce its thickness, then push open again, accumulated snow is avoided not have push plate to stay in road surface, improves the effect of snow removing.
To achieve the above object, the present invention adopts the following technical scheme:
The present invention provides a kind of Semi-automatic small snow breaker, including walking mechanism, the walking mechanism includes car body, vehicle
Outside is provided with the wheel that can drive body movement, and the top surface of car body is fixedly connected with headstock, and car body is close to vehicle with walking machine
The side of structure direction of advance is fixedly installed horizontal limit plate, and the through-hole on vertical direction is offered on limit plate.It is described dynamic
Power case provides power by motor, and the output par, c of motor is fixedly connected with transmission shaft, and transmission shaft is parallel to the advance side of walking mechanism
To the top surface with car body, transmission shaft is fixedly connected with first connecting rod one end perpendicular to transmission shaft, the other end hinge of first connecting rod
Connect one end of second connecting rod, one end of the hinged push rod of the other end of second connecting rod, through-hole of the push rod on limit plate, and with it is logical
Hole cooperates, and the other end of push rod is fixedly connected with horizontal pressing plate, and fluffy accumulated snow can be compacted by moving up and down for pressing plate.
The bottom surface of limit plate is fixedly connected with push plate, and push plate is between car body and pressing plate.The top surface of car body, which is fixedly connected with, marches forward instead
The inclined manipulation frame in direction, manipulation frame are used for the direction of advance of manual control walking mechanism, and the top for manipulating frame is fixedly installed
Handrail.
It further, is the stability and passability for improving walking mechanism, the wheel at least 4, outside the wheel
Side is provided with rotary crawler belt.
Further, the walking mechanism provides the power to advance by artificial or engine.
Further, the cross section of the push plate is arrowhead-shaped so that push plate in movement forward by accumulated snow to two
While pushing open.
Further, to prevent Snow Thickness increase from not crossing push plate, the height of the push plate is at least 10cm.
It further, is the energy loss in mitigation transmission process, the transmission shaft, first connecting rod, second connecting rod, push rod
It is hollow structure with pressing plate.
Further, the car body top is equipped with 4 or more the sprays in the process that can advance with the spraying head of salting, snow breaker
The accumulated snow salting that sprinkle head is pushed open to two sides by push plate accelerates it and melts speed.
The beneficial effects of the present invention are:
The present invention is provided with pressing plate in front of the push plate of snow breaker, and pressing plate constantly moves up and down during snow breaker advances,
By accumulated snow compacting fluffy in front of snow breaker, the accumulated snow of compacting pushes both sides to by push plate again, since thickness reduces after accumulated snow compacting,
Push plate is avoided during snow pushing, fluffy Snow Thickness is more than push plate height, does not have push plate to fall back to so as to cause accumulated snow
The case where ground, greatly improves the efficiency of cleaning snow of small-sized snow-removing machine.
