Description
Technical field
The present invention relates to a kind of snow-clearing car.
Background technology
The mode of snow removing is a lot, and as snow removal with machine, snow melt snow removing, composite type snow removing etc., as its name suggests, snow removal with machine is the method for removing accumulated snow by plant equipment.Snow melt snow removing is to utilize heat energy or spreading chemical agent and a kind of method of making snow melting.The composite type snow removing is a kind of snow-removing method that snow removal with machine combines with the snow melt snow removing, and these three kinds of snow-removing methods respectively have its characteristics, and snow removal with machine is most widely used, its reason is its snow removing efficient height, cost is low, and is pollution-free, but to ice-patch surface and inferior grade road surface snow removing weak effect.Mainly be applicable to the airport, speedway and main streets snow removing.Snow melt snow-removing method cost height easily pollutes and corrodes environment and road surface, generally uses lessly, is mainly used in local snow removing such as ice-patch surface and sloping road.
Snow scraper tool equipment all has production both at home and abroad, is mainly used in the area that snowfall is big, weather is cold.The northern area of China has special large-scale Snow shoveling device tool.But for few and the little Yangtze river basin and the areas to the south of snowfall of snowing, accumulated snow also is a problem.And south all is to adopt hand labor to clear the snow basically.If introduce road surface accumulated snow cleaning machine, as impact type road ice-breaking machine, automatic snowplow etc., but often volume is bigger for these snow-removal machines, complex structure, though its operating efficiency is higher, but one-time investment is big, costs an arm and a leg, and inconvenient maintenance breaks down, for not spacious places, place such as narrower sidewalk, residential quarter, access bridge, bypass, access, hard shoulder peripheries, the removing of accumulated snow is unworthwhile.Also all at large-scale road design, other most local manpowers that lean on are removed with instruments such as spades at the general snow shoveling machine of China, and labour intensity is big, the time is long.In manpower sweeps away snow, lack facility instrument efficiently at present.The existing on the market road apparatus that clears the snow, some more advanced snow scrapers are that the hot gas power by high pressure melts and washes away ice and snow, and cost is very high, and most of machineries rely on diesel engines or Motor Drive, can not get extensive use.
The product of summarizing on the market has following shortcoming:
(1) use snow melting agent (salt) to clear the snow.A large amount of long-term chemical Snow Agent snow removings of using, the vegetation of road both sides is damaged, the vehicles etc. are corroded, chemical reaction takes place in pitch, concrete (cement) road surface and snow melting agent (salt), the heavy corrosion road surface, become crisp, become fragile, form be full of cracks, thereby service life well below design period has shortened the maintenance cycle of road.The use of snow melting agent has caused the waste that drops into directly or indirectly, and the snow-melting agent after dissolving flows into rivers, causes the salinization of soil of soil, downstream, has fundamentally made pollution sources artificially, has destroyed environment.
(2) snow removal with machine is the method for removing accumulated snow by plant equipment.Most of plant equipment form such as shovel, rob, push away, dig, cut all is very stiff and demanding, the flatness on any road surface is not absolute, because of when mechanical work, the recess on road surface is not in place clearly, and ice and snow has residual, and protruding place contacts with the parts that clear the snow, form friction, mechanical wear has been quickened in collision, the damage road surface, and clearance rate is not high yet.
(3) the general power of motor vehicle snow removing equipment is bigger, and powerful, but it bulky simultaneously do not have too big effect to zonule, among a small circle snow removing.Because bulky, equipment configuration and maintenance are also very inconvenient simultaneously.
Summary of the invention
Deficiency for not convenient property that clears the snow in the small area that overcomes existing snow clearing equipment and the no thoroughness that clears the snow the invention provides a kind of can clearing the snow easily, the human double-shovel snow-clearing car that snow-removing effect is good in small area.

Transmission mechanism: people's power drives the rotation of front axle 2-2 via the first chain drive group and the second chain drive group, thereby drives wheel 2-3, wheel 2-1 servo-actuated.Meanwhile, front axle 2-2 drives driven gear 9-3 by driving gear 9-4 and makes broken snow roller 3 counter motions.Clutch is made of driven gear 9-3 and driving gear 9-4, and by the effect of control lever 9-1, visual snow condition is controlled the motion of broken snow roller 3.Also be accompanied by the motion of bevel gear 20-1,20-2 in the carrying out of the first chain drive group, the transmission of hairbrush 5 causes thus.
The mechanism that clears the snow mainly is divided into three parts:
One, V-shape plough formula shovel snow cutter (two ones): the promotion operation by V-shape plough formula shovel snow cutter 10-1,10-2, snow is pushed into both sides, plough the effect that the formula structure is turned on having simultaneously, help rooting out of accumulated snow.The outfit of two shovel snow cuttves makes shovel snow cutter with better function.
Two, broken snow roller: the double action that the reverse rotation campaign of broken snow roller 3-2 is turned over and smashed on accumulated snow is had.On turn over and beat loose accumulated snow, sting and brokenly makes pine avenge fragmentation, be beneficial to removing.Clutch 9 is made of driving gear 9-3 and driven gear 9-4, and by the effect of control lever 9-1, visual snow condition is controlled the motion of broken snow roller 3, and gears engaged is then worked, and separates then to quit work.
Three, hairbrush: drive bevel gear 20-1,20-2 and caused brush stroke 13 rotation by the motion of dynamic bevel gear 20-3,20-4 drive hairbrush 5 motions, realize the function of the residual snow of cleaning.
