Description

TECHNICAL FIELD

[0001] The utility model belongs to snow blower technical field, concretely relates to a snow discharge adjusting device and snow blower. BACKGROUND

[0002] In the traditional snow blower design, the snow throwing pitch angle adjustment and the left and right sweeping angle adjustment are usually realized by two independent mechanical mechanisms, and the two mechanisms are responsible for controlling the snow throwing height and the snow throwing direction respectively. For example, the user first adjusts the snow throwing pitch angle of the snow blower through a handle or a pull rod, and the angle determines the height at which the snow blower throws snow. The user needs to manually pull or push the handle until the desired angle is reached. After completing the adjustment of the snow throwing angle, the user needs to switch to another handle or pull rod to adjust the left and right sweeping angle of the snow blower, and this angle determines the snow throwing direction of the snow blower when sweeping snow. The user also needs to manually operate. Since the two mechanisms are independent, the user needs to switch between the two handles when adjusting, which increases the complexity and time of operation. Frequent manual switching not only reduces the operation efficiency, but also may cause the user to lose control of the snow blower state during the adjustment process, especially in complex snow sweeping environments. Long-term repetitive operation can easily cause the user to feel tired, especially in long-term snow sweeping tasks. The complexity of operation will significantly affect the user's experience.
