Single-gear multi-variable speed snow sweeper with safe manipulating and front assisting wheels and noise reducer body

Abstract

The invention relates to a light self-propelled snow sweeper, which comprises an anti-skid chain, a snow-ice tooth brush auger, a heat transfer steam tank and a front exhaust pipe and is a single-gear multi-variable speed snow sweeper with safe manipulating, front assisting wheels and a noise reducer body. A water tank is arranged on a silencer to cool and lead hot steam and hot waste gas to the snow-sweeping front part through a silencing tube so that the ice is removed because of local heating frangibility; variable-speed skidding is majorly improved, and a single gear is changed into a front and rear multi-speed mode so that the coordination of a drive move wheel (26) and a variable slipping poked wheel (27) is multi-bevel gear meshing or comprehensive cooperation between a convex and concave pitted surface and a gear; a die is adopted to cast or inject, so machining is not utilized and low cost is achieved; a safety control handle is also utilized; a front caterpillar band or the front assisting wheel is adopted to assist steering, and the noise reducer body is provided. Burning and cooling, difficult noise reduction, skidding halt, counter weight anti-skidding, waste suction health, secondary gas mixing, heat insulation and shock absorption, deicing function and snow casting function are comprehensively improved, and in other words, a new technical field of cooling, noise reduction, energy conservation and emission reduction of a single-gear variable-speed walk machine is initiated, for example a single-gear variable-speed mower.

Description

technical field [0001] The invention relates to a light-duty self-propelled snowplow used for cleaning snow in front of office buildings, courtyards, sidewalks and other places. On the basis of Longhe snowplow with heat transfer steam tank and front exhaust pipe, the snowplow with single chainring and multi-speed is further improved with safe operation, front auxiliary wheel and noise reduction body. Background technique [0002] Although it is a good year for auspicious snow, the snow on the road has affected the traffic. The use of large-scale power snowplows on the main road is huge and expensive, and it will be labor-intensive and inefficient if the tactics of crowds are used. Therefore, various light and small snowplows have emerged as the times require. The necessary machine for clearing snow in winter is widely used in parking lots, squares, property communities, gardens, bicycle lanes and many other places. But any product is not perfect, and there are always many ...

Problems solved by technology

Common mufflers for internal combustion engines, especially those used for small gasoline engines, are mostly three-chamber mufflers with limited muffler effect; and a larger protective cover must be provided outside, such as Figure 7 As shown in the outer cover (19b) of the three-dimensional schematic diagram of the snowplow, it has no noise reduction effect, and the temperature rise of its shell is extremely high. There are many types of common models, not only snowplows, but also lawn mowers. Although the muffler has an outer cover, it is not very useful, and it is still hot, which affects safety and cannot completely solve the problem

When using a snowplow, you often encounter many unexpected situations: Sometimes when plowing snow, especially when the snow and ice are mixed, or when the road conditions are poor, the various problems of the original snowplow will appear more or less for some reason For example, the auger without ice-toothed snow brush and the snow shovel in front of the snow sweep sometimes have insufficient snow intake; the throwing effect of the snow throwing disc is not obvious and the throwing is not far away; ;The toothless ice and snow shovel is not easy to use when encountering a little thin ice; the side front steering gear is difficult to push when the snowplow turns sharply; the large walking wheel without anti-skid chains slips along the ground and cannot move forward Pushing snow; even if the hand holding the handle of the drawstring hurts; Figure 7 The fence of the model is too far away from the engine, people can't reach the control; and its operating handle has no safety measures for misuse protection; how to solve and how to prevent the occasional shortcomings and shortcomings of many snowplows has always been the leader in this field Difficult question
