Description

Technical Field

[0001] This utility model belongs to the field of snowplow technology, specifically relating to a snowplow exhaust pipe. Background Technology

[0002] The snow discharge tube is a crucial component of a snowplow, working in conjunction with the snow throwing mechanism to direct snow to a suitable area. It primarily consists of a separate snow-throwing hood and a snow-guide hood, which are movably connected. An angle adjustment mechanism allows for adjustment of their relative angle, altering the snow-throwing height and angle. However, existing snowplows often employ cable-operated snow discharge tube angle adjustment mechanisms, such as the Chinese utility model patent CN 212223745 U. This design uses a snow discharge tube cable disc, a snow discharge tube cable, and a cable pulley, driven by a stepper motor to adjust the angle of the snow-throwing nozzle. This complex structure requires multiple components to work together, leading to reduced reliability and high maintenance costs. Furthermore, most of these components are located externally to the snow discharge tube, affecting the overall compactness and integrity of the structure. Summary of the Invention

[0003] This invention addresses the problem of complex structures in existing snow discharge tube angle adjustment mechanisms by providing a snow discharge tube for a snowplow. The objective of this invention is achieved through the following technical solution:

[0004] A snowplow exhaust duct includes a separate snow guide cover and a snow throwing cover. The snow throwing cover is rotatably mounted at the front end of the snow guide cover, and the two together define a snow discharge channel. The snow throwing cover and the snow guide cover are equipped with mutually cooperating angle adjustment mechanisms. The angle adjustment mechanism includes a hinge platform fixed to the top of the snow guide cover and an adjustment handle mounted on the snow guide cover. The top of the hinge platform is formed with locking teeth. The adjustment handle includes a fixed handle fixed to the top of the snow guide cover and a movable handle hinged to the bottom of the fixed handle. The movable handle has adjustment teeth that can engage with the locking teeth. The movable handle can reciprocate between a locked position and an adjustment position. When the movable handle is in the locked position, the adjustment teeth engage with the locking teeth, and the snow throwing cover and the snow guide cover remain fixedly connected. When the movable handle is in the adjustment position, the adjustment teeth disengage from the locking teeth, and the snow throwing cover can rotate relative to the snow guide cover under the action of the adjustment handle to achieve angle adjustment. A locking spring is installed between the movable handle and the fixed handle to keep the movable handle in the locked position.

[0005] Preferably, the movable handle is segmented, including an operating segment and an adjusting segment. The end of the operating segment is hinged to the fixed handle, the adjusting segment is arc-shaped, and the adjusting teeth are formed at the bottom of the adjusting segment.
