Snow shovel with multi-directional adjustable snow shovel

Abstract

The present invention provides a snow shovel with a multi-directional adjustable snow shovel. It solves the problem that the snow shovel can only rotate up and down and has low snow removal efficiency. The present invention adjusts the distance between the support seat and the support frame by adjusting the extension and contraction of the height adjustment handle adjustment cylinder to rotate the rotating frame to adjust the angle of the snow shovel in the vertical direction. The snow shovel is rotated around the rotating shaft by the adjustment device and the snow shovel is locked by the locking device to complete the adjustment of the angle of the snow shovel in the horizontal direction. The adjustment is relatively convenient and quick, so that the snow shovel can perform efficient operations in different situations. When in use, the snow on the snow shovel can be guided by removing the side plate on any side of the arc plate so that the accumulated snow slides down along the fixed direction on the arc plate, which is relatively convenient to use.

Description

Technical Field

[0002] As a hand-pushed power tool, a snowplow can be used as an important equipment for winter snow removal. It has major advantages such as high efficiency, economy, and environmental protection. With the growing economic strength and continuous social progress, snow removal equipment has been gradually promoted and used at home and abroad. Snowplows have the advantages of simple operation and high work efficiency. Snowplows mainly use snow shovels to shovel the snow on the road to one side of the snow shovel. The existing snowplows mainly rotate the snow shovel set at the front end of the frame to achieve the up and down rotation of the snow shovel. Therefore, it is impossible to increase the left and right rotation structure of the snow shovel. The snow shovel can only adjust the distance between the lower end of the snow shovel and the ground by rotating up and down to achieve work efficiency under different use conditions. However, the snow shovel that cannot be rotated in the left and right directions is easy to accumulate on one side of the snow shovel and fall on the road during actual use, which greatly reduces the snow removal efficiency of the snowplow.
