Description
Technical Field
The utility model relates to a highway maintenance technical field, concretely relates to snow sweeper.
Background
The accumulated snow on the road in winter can cause great influence on the traveling of people, particularly in the north China and the northeast China, because the weather of the areas is very cold, the snow fall amount is generally large, and the snow is not easy to melt, and can be frozen even in a short time, so that the road adhesion coefficient is reduced. In China, traffic accidents caused by snow are frequent every year, and normal travel cannot be realized due to the fact that snow is blocked, so that not only is life inconvenient, but also a part of people suffer from huge economic loss, and therefore snow removal is very important in time after snow is discharged. The snow shoveling vehicles used at present mainly aim at large snow shoveling vehicles on expressways or main streets, but are rare for small snow shoveling vehicles in small streets, squares and other areas closely related to the daily life of people, and snow removing in the places mainly depends on manual snow removing, namely manual shoveling is firstly carried out, and sweeping is carried out by using a broom. The efficiency of manual snow removal is very low, and the number of people who move is more, and the cost is expensive.
Therefore, Chinese patent with publication number CN204589901U discloses a novel snow removing vehicle, which comprises a tractor, a hydraulic cylinder, a snow removing shovel lifting rod, a snow removing shovel, a snow raising cylinder, a snow brush, snow brush bristles, a snow brush shaft, a snow brush outer cover, a fixing plate, a snow brush motor and a snow brush roller; the snow brush is composed of snow brush bristles and a snow brush roller. When snow is thicker in this scheme, snow removing shovel and snow brush work jointly, and snow removing shovel at first shovels away the most snow on thick snow layer, and snow brush is the rotation of flying speed, lifts remaining snow to raise the roadside through the snow raising barrel, and when snow is thinner, snow removing shovel does not carry out the snow removal operation when the snow brush is enough with snow clean up, and snow brush is the rotation of flying speed, lifts the snow, and raises the roadside through the snow raising barrel.
The snow sweeper in the prior art is also a snow sweeper, and comprises a tractor, a snow sweeping action unit arranged at the front end of the tractor, and a power unit for driving the snow sweeping action unit to operate, wherein the snow sweeping action unit comprises a snow brush roller structure (composed of a roller and bristles arranged on the surface of the roller) and a transmission structure; when the snow sweeper is used, the power unit and the transmission structure drive the roller and the bristles to rotate to sweep snow. However, in actual use, obstacles such as stones (particularly obstacles capable of hitting against the roller) may exist on the ground to be cleaned, and the obstacles are covered under the accumulated snow and are difficult to find; when snow is cleaned, the tractor pushes the snow cleaning action unit to continuously move forward, and when the snow cleaning action unit meets obstacles, the roller of the snow brush roller structure can be abutted against the obstacles (the obstacles cannot be seen by an operator), so that a transmission shaft of the transmission structure can be subjected to great torsional force; the transmission shaft of the transmission structure is made of a rigid material (in order to ensure the transmission efficiency of the transmission structure), and when the received torsional force exceeds a certain limit, the transmission shaft is easy to irreversibly damage or even break.
