Background
In winter, especially in northern areas, snowfall is frequent, freezing time is long, snow removing operation is often carried out by using a method of spreading snow-melting agent by using a snow-removing spreader, and a spreading device of the existing spreader mostly realizes a height adjusting function of a spreading mechanism through manual or hydraulic driving.
The manual adjustment mode mainly comprises the step of manually adjusting the position of a handle to drive the spreading blade disc to reach a proper height so as to finish the work of spreading the snow-melting agent. The temperature is low in winter, and is not suitable for personnel to work outdoors for a long time, and the manual adjustment of the height of the spreading disc is time-consuming and labor-consuming, and the manual acting force is uneven, so that equipment failure is easy to cause in a low-temperature environment.
In order to reduce the difficulty of manual snow removal and improve the snow removal efficiency and the automation degree, an automatic spreader and wide application are realized in the prior art.
