Description

Technical Field

[0001] The utility model relates to the technical field of snow sweepers, in particular to a snow sweeper. Background Art

[0002] In today's life, more and more aspects have been replaced by machines instead of manpower, saving a lot of labor costs, including snowplows. In the past, snow was swept manually. People took a broom to sweep snow on the street, but it was quite strenuous, especially when the snow was too deep, it required a lot of effort. Since the emergence of snowplows and snowplows, work efficiency has been greatly improved, and a lot of manpower has been saved.

[0003] At present, most of the driving components in snowplows use brushless motors or brushed motors. Compared with brushless motors, brushed motors have a shorter service life and are prone to sparks and electromagnetic interference during movement, which affects its project application and has low reliability. Although brushless motors have good heat dissipation, long service life, and no sparks and electromagnetic interference, their structure is relatively complex. Once damaged, they need to be replaced as a whole, with high manufacturing costs. They vibrate more when starting and need to reach a constant speed before they can be stable. On the contrary, the internal structure of brushed motors is simpler than that of brushless motors, and the technology development is relatively mature. During maintenance, it is often only necessary to replace the brushes, and the manufacturing cost is low. Therefore, it is particularly important to ensure that the snowplow has a long service life, better use effect, and low maintenance cost. In addition, most snowplows have an automated and convenient snowplowing effect that helps manual labor, but when the snowplow is driven by a motor at high speed, it is very easy to cause snow splashing, which in turn causes snow splashing onto the user, thereby reducing the use effect of the snowplow.
