Lifting and swinging hydraulic device for snow remover and snow remover with same

Abstract

The invention discloses a lifting and swinging hydraulic device for a snow remover and the snow remover with the same, relates to an upper hydraulic device for a snow remover and the snow remover, and solves the problems of high labor intensity of snow removing operation because the conventional snow remover is not provided with the hydraulic device, low transmission efficiency and easy damage of the convention snow remover and the like. An engaging lug on the bottom end face of a cylinder body of a lifting oil cylinder is hinged with that on an inclined plate through a movable pin shaft of the lifting oil cylinder. A rod end of the tower bottom end of an A-shaped frame body is hinged with the engaging lug on a corresponding sub-plate through an integral movable pin shaft, while the other rod end of the tower bottom end of the A-shaped frame body is hinged with the corresponding engaging lug on the other rod end through the integral movable pin shaft. A snow removing roll is arranged on a rolling brush shaft; a connecting rod end of the lifting oil cylinder is connected with an upright post on the middle part of the rear end of a main framework; and a connecting rod end of the swinging oil cylinder is connected with a side end plate on the main framework. The hydraulic device relieves the labor intensity of the snow removing operation, is safe and reliable, has stable operation, doubles the torque, and improves the efficiency by 50 percent.

Description

technical field [0001] The invention relates to an upper hydraulic device for a snow blower and the snow blower. Background technique [0002] At present, the existing snow blower uses a manual chain guide jack to complete the lifting and swinging actions of the whole machine, which is cumbersome to operate and has low work efficiency. Existing snow blowers all adopt water-cooled diesel engines, and the output is driven by a V-belt or a reducer. The disadvantage is that the V-belt drive has the disadvantages of easy slipping (especially in winter), fatigue and elongation caused by high-speed rotation and heat generation; low transmission efficiency and small torque. At present, the maximum input speed of the reducer in China is 1500r / min, and that of the water-cooled engine is 2200r / min. The shaft has large runout, instability, and large torque loss, so it has the defects of easy damage, short life, low efficiency, and high maintenance cost. Contents of the invention ...

Problems solved by technology

[0003] The object of the present invention is to provide a lifting and swinging hydraulic device for a snow blower and a snow blower with the device, so as to solve the problem that the existing snow blower is not equipped with a hydraulic device, which causes the labor intensity of the snow clearing operation to be high and the current situation. Some snow blowers have problems such as low transmission efficiency, easy damage, and short service life.
