Tire type high-speed bulldozer work device

Abstract

The invention discloses a tire type high-speed bulldozer work device, and belongs to the technical field of engineering machines. The front end of a left push arm and the front end of a right push arm are hinged with the work device, the rear end of the left push arm and the rear end of the right push arm are hinged to a main engine, an adjusting rod is hinged between the left push arm and the work device, the front segment and the rear segment of the left push arm are straight rods, an arc segment which is bent downwards is arranged between the front segment and the rear segment of the left push arm, when the work device works, the included angle alpha between the connecting line between the front hinge point and the rear hinge point of the left push arm and the horizontal ground is larger than or equal to 5 degrees and smaller than or equal to 6 degrees, and horizontal rods are hinged between the left side of the left push arm and the work device and between the right side of the right push arm and the work device; and locking mechanisms are connected between the left push arm and the main engine and between the right push arm and the main engine. Effective transmission of moment during work can be ensured, vehicle high-speed running performance can be achieved, safety of a bulldozer at the high speed is ensured, the bulldozer can be rapidly transferred, and work efficiency is improved.

Description

technical field [0001] The invention relates to a construction machinery working device, in particular to a tire type high-speed bulldozer working device. [0002] technical background [0003] A bulldozer is an earth-moving machine capable of excavating, transporting, and discharging rock and soil, and is widely used in open-pit mines. [0004] Most of the current tire-type bulldozer working devices are push arms installed on the outside of the tire. The push arm and the main machine are connected by a push knife bracket, resulting in a large moment arm between the push arm and the main machine during bulldozing operations, resulting in The effective transmission of torque is reduced, and when the bulldozer is in a driving state, it cannot travel at a higher speed, and cannot quickly transfer the work site, which reduces the operating efficiency. Contents of the invention [0005] In order to solve the above technical problems, the present invention provides a tire-type h...
