Description

Snow outlet direction adjusting mechanism of snowplow Technical Field The utility model relates to the technical field of snowploughs, in particular to a snow outlet direction adjusting mechanism of a snowplow. Background In winter, snow can bring a plurality of inconveniences to road traffic and daily life of people, and the snowplow plays an important role in removing road snow, guaranteeing smooth traffic and the like as an efficient snow removing device. In the actual use process of the snowplow, the adjustment of the snow throwing angle is an important function, and the snow throwing angle can enable snow to be thrown to different positions so as to adapt to various different snow sweeping scenes, such as roads, squares, parking lots and the like, and accurately throw snow to the designated positions. The snowplow realizes the adjustment of throwing snow angle through adjusting the circumferential rotation of a snow outlet cylinder and the vertical overturning of a snow pressing cap, and the vertical overturning of the snow pressing cap is mainly adjusted through a handle, and the traditional handle adjusting structure is mainly divided into a multistage adjusting mode and a stepless adjusting mode. The stepless regulation mode is to utilize the dynamic and static friction force between the friction plate and the handle rod to realize the rotation of the regulating handle and maintain the stable state. Specifically, a certain force is applied to the friction plate in the rotation axis direction to ensure that the handle bar is stabilized at a certain angle. However, this approach has significant drawbacks. With the increase of the service time, the friction plate can be gradually worn, and the static friction force between the friction plate and the handle rod can be reduced, so that the handle rod is difficult to maintain a stable angle, and the accuracy and stability of the snow throwing angle are affected. The multistage adjustment mode realizes the adjustment function of the snow throwing angle through the position relation between the limiting rack and the handle rod. In general, the tooth direction of the rack is the same as the axial direction of the handle bar, so that the limit of the handle bar is realized. When adjusting, the user needs to apply an axial force to overcome the meshing resistance between the toothed plate and the handle, and then apply a tangential force to rotate the handle. Both steps require additional force, especially when the engagement between the toothed plate and the handle is relatively tight, and applying axial force may be difficult and require more force. The existing multistage snow throwing angle adjusting mechanism has the defects that the traditional adjusting mode often needs larger axial force to adjust the angle, the operation is more laborious, and the rack is exposed outside to easily cause collision of operators, so that the safety is low. Therefore, there is an urgent need in the market for a snow throwing angle adjusting structure that is more convenient, labor-saving and safe.
