Description

Technical Field

[0001] The utility model relates to the technical field of snow shovel devices, in particular to a scraping type snow shovel. Background Art

[0002] Snow shovels are a commonly used road snow removal device. There are many types of snow shovels. According to the power source, they can be divided into two categories: electric and engine-powered. Among them, electric snow shovels must have a power source, so their use is limited. Engine-powered snow shovels must be equipped with a power engine, which is more troublesome to produce, use and maintain. For example, in the existing technology, there is a snow shovel that is particularly suitable for small cars such as cars. Its main feature is that it is equipped with a hydraulic system that can control the snow shovel in the snow shovel to move from one side to the other, and can also lift and drop the snow shovel. Existing snow shovels are generally bulky and inconvenient to transport.

[0003] In order to solve the above problems, the utility model patent with authorization announcement number CN202969321U applied by the applicant discloses a mounting structure of a scraper-type snow shovel wheel suitable for installation at the front end of a vehicle. The above scheme can set different heights of the wheel on the snow shovel through the mounting structure of the wheel of the utility model, that is, when the snow shovel is working, the wheel is placed at the highest position, so that the wheel is suspended in the air and does not affect the work of the snow shovel; when the snow shovel is finished and separated from the car, the wheel is placed at a low position so that the wheel contacts the ground, so that the snow shovel can be moved quickly and conveniently. The utility model has a simple structure, low cost, safety and reliability, and is easy to use.

[0004] However, the wheel mounting structure in the above scheme is distributed on the swing frame. When the snowplow is docked and assembled with the vehicle body, since the weight of the snowplow is mainly concentrated on the snowplow board, the snowplow is easily tilted toward one end of the snowplow board when the wheel mounting structure is used for support, making it inconvenient to assemble the other end of the snowplow with the vehicle body.
