Technical field

The present invention has adopted the snow removing mechanism that a kind of novel dashing shoveled and shoveling combines; Can remove to high in efficiency and convenience the floating accumulated snow of avenging and being compacted through a kind of snow removing machinery simple in structure; Formed with the shoveling of floating snow, hard ice and snow elder generation swing crushing is the snow removing mechanism of shoveling again.In addition because this snow removing machinery can either again can people's force urges through trailer towing, just change dimensionally and can on the road of broadness and narrow sidewalk, reach good snow removing effect so need only, have very strong practicality.

Background technology

Increase along with northern road construction and traffic density; Heavy snow will bring greatly obstruction to road traffic like the ice and snow that can not in time remove on the road later in the winter time; And conventional artificial first snow and snow-melting agent snow removing are owing to reasons such as inefficiency and environmental protection more and more can not satisfy actual needs, so utilize the mechanical trend from now on that remains that removes the snow.But at present generally all there is the deicing function singleness in existing snow removing machinery product on the domestic and international market, and efficient is not high, unit characteristics such as cost an arm and a leg.Develop for this reason a kind of economical, function strong, adapt to wide snow removing machinery.

Shoveling formula snow removing tool is that present road floating ice snow is removed the fastest, simple in structure, the most effective snow removing equipment of mechanical removing speed, but can not remove compacting ice and snow and road ice and snow mixture; And that the snow removing machinery ubiquity of existing removing compacting ice and snow and road ice and snow mixture speed is slow, problem such as efficient is low.Therefore, with shoveling with to dash the design that the shovel function combines be fundamental guiding ideology of the present invention.Purpose is exactly the requirement that adapts to the different kinds of roads ice and snow removing, develops economic, practical, efficient, safe cold ground new road ice and snow removing equipment.Machinery of the present invention in addition both can be removed the accumulated snow on the broad road with trailer towing, can artificial traction remove the accumulated snow in some narrow places for power again, so be suitable for relatively extensively.

This patent has carried out detailed design in the driving mechanism that dashes shovel, the fluid power system of dashing shovel and the power drive system of whole machinery.The driving mechanism that wherein dashes shovel be with cam structure as core, with the driving power of compression spring, move to the high point process from low spot at cam as vibration, spring is compressed; In the process that cam is put from the low spot to the height, spring is released, and dashes shovel around propping up spot wobble and cutting the snow piece sideling thereby make, and gets to the purpose of shatter accumulated snow.In the hydraulic control system of shoveling, the utilization of overflow valve can make shoveling when running into obstruction, dodge, and is carrying out normal operation during avoiding obstacles, has greatly improved the damage of safety and road pavement.The power drive system design of whole machinery makes every effort to make the used parts standard of trying one's best to draw, and structure is simple as far as possible.

The specific embodiment

As shown in Figure 1,1. be fuel tank; 2. be strainer; 3. be gear pump; 4. be one way valve; 5. be overflow valve; 6. be that flow speed control valve 7. is hand control valve; 8. be oil pipe; 9. be hydraulic cylinder; 10. be piston rod.

Hydraulic oil is through the effect of hydraulic pump 3; Pump hydraulic oil by fuel tank 1; Filter through strainer 2, hydraulic oil flow gets into hydraulic cylinder 9 through hydraulic pump 3, one way valve 4, flow speed control valve 6, hand control valve 7 and oil pipe 8; Thereby drive piston rod 10 motions in the hydraulic cylinder 9, promote shoveling and carry out the snow pushing operation.Along with the carrying out of snow pushing operation, the accumulated snow of shoveling front constantly increases, and accumulated snow also constantly increases through the load force that shoveling passes to hydraulic cylinder 9; This moment is under the effect of hydraulic pump 3 and flow speed control valve 6, and the pressure of the import and export through flow speed control valve 6 also increases accordingly, according to the function of selected flow speed control valve 6; The pressure differential that can guarantee flow speed control valve 6 front and back remains unchanged basically, thereby can guarantee the relatively stable of system works, reaches certain value if act on the load force of hydraulic cylinder 9; Through regulating the pressure of safety valve in the flow speed control valve 6, when load acts on the hydraulic cylinder 9 pressure when equaling the pressure in exit of flow speed control valve 6, safety valve will be opened; Make the pressure in exit of flow speed control valve 6 no longer raise; And when pushing snowboard was run into obstruction, the precompression through adjustment overflow valve 5 acted on the safe pressure of the load force of hydraulic cylinder piston rod 10 greater than overflow valve 5; Overflow valve 5 is opened; Piston rod 10 will be moved to the left, and make shoveling planar to rotate around fulcrum around fixing pendulum, thereby can well avoiding obstacles.When the smooth avoiding obstacles of shoveling, the active force that acts on liquid presses piston pole 10 through shoveling will reduce rapidly, will be less than the adjustment safe pressure of overflow valve 5, so piston rod 10 will move right, shoveling will be proceeded Snow pushing operation.And after snow removing is accomplished, move hand control valve to left side position, and the hydraulic circuit switching-over makes piston rod 10 returns, turns off power source, and snow removing tool is shut down smoothly.

As shown in Figure 2,1. be road accumulated snow; 2. for dashing shovel; 3. be driving spring; 4. be rocking bar; 5. be fulcrum; 6. be camshaft; 7. be cam; 8. be sprocket shaft.

When snow removing tool removed the snow, the power transfer unit sprocket shaft 8 of snow cave shovel driving mechanism was accepted the power of running part, then through the sprocket wheel effect on the sprocket shaft 8; Under the transmission of roller chain, rotary power is passed to camshaft 6, camshaft 6 is accepted the power rotation; Thereby the cam 7 that drives on the camshaft 6 rotates, and cam 7 is combined closely with rocking bar 4, under the driving of cam 7; When cam 7 by minimum point when peak rotates, rocking bar 4 can planar be done gyration around fulcrum 5, promotes to dash shovel 2 compression springs 3; Make spring 3 produce the thrust that satisfies the snow removing condition; When cam 7 is slided in the blink of minimum point by peak, the spring 3 that compresses is released, and shakes road accumulated snow broken thereby promote to dash shovel 2.Dash shovel 2 in operation, the track of motion is a cycloid.

As shown in Figure 3,1. for dashing shovel; 2. be road accumulated snow.

The snow removing principle of snow cave shovel 1 is as shown in the figure, when snow cave shovel 1 moves to liftoff height and is H, under the effect of spring, does the pendulum model cycloid motion, in the moment that contacts with ground with thick for the compacting ice and snow of h sweeps, and reach the purpose of the broken accumulated snow that shakes.
