Snow sweeper adjusted and controlled through pull rope

Abstract

The invention provides a snow sweeper adjusted and controlled through a pull rope. A left trigger and a right trigger are in linkage through the pull rope. When the left trigger is held by a left hand, the pressed-down right trigger can be automatically in linkage after a right hand is moved away and is kept pressed down, and therefore the right hand is released to poke other handles of a panel operation part. The right trigger and the left trigger share the same self-locking pull rope (141) connected into a self-locking pull rope hole of the end portion of a hook of a right trigger self-locking board (158). A cylindrical self-locking block is arranged on the left face of the two parallel faces of the right trigger self-locking board (158) and acts with a self-locking sunken hook of the right trigger, so that the left trigger and the right trigger are in linkage, and the self-locking sunken hook is of a logarithmic spiral shape with the characteristic that the pressure angles at all positions are equal. Each snow throwing blade (18a) is a blade face of a logarithmic spiral shape with the characteristic that the pressure angles at all positions are equal or a blade face of a cubic curve shape with an impact reducing characteristic. An ice shoveling board, a front caterpillar band and front auxiliary wheels are made of polysulfone plastic. Polarized light with the main wavelength of 588 nanometers when irradiating in haze is adopted as lamplight of a lamp panel. The functions of burning cooling, noise reduction, sliding prevention, balance weight skid resistance, waste gas inhalation health prevention, secondary gas mixing, thermal insulation and damping, ice removing and snow throwing are comprehensively improved.

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, it is a perfect snowplow with chainrings controlled by pull ropes and multi-speed with safe control, front auxiliary wheels 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 al...

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
