Working device of wheeled dozer

Abstract

The invention discloses a working device of a wheeled dozer. The working device of the wheeled dozer comprises a scraper knife, big arms, sideward and forward inclined oil cylinders, a triangular support and a lift cylinder, wherein the big arms are combined with the two sides of the scraper knife respectively in a hinged mode, the sideward and forward inclined oil cylinders are connected between the scraper knife and the big arms in a hinged mode, and the triangular support and the lift cylinder are combined with the middle of the scraper knife in a hinged mode. The front end of each big arm is hinged to the scraper knife through a spherical hinge, and the rear end of each big arm is hinged to a thrust beam of a front vehicle frame through a spherical hinge; a ground flattening device is arranged below the scraper knife and at the rear of a knife edge of the scraper knife; the combined ends of each sideward and forward inclined oil cylinder and the scraper knife are hinged through a spherical hinge, and the combined ends of each sideward and forward inclined oil cylinder and the corresponding big arm are hinged through a spherical hinge; the triangular support and the lift cylinder are hinged to the middle of the scraper knife in spherical hinges, and the triangular support is hinged to the front vehicle frame through a pin shaft; the lift cylinder is hinged to a supporting cross beam of the front vehicle frame through a spherical hinge. The working device of the wheeled dozer enables a soil cutting angle of the scraper angle to be adjusted, can flatten a working face, and greatly improves production efficiency.

Description

technical field [0001] The invention relates to a tire type bulldozer, in particular to a tire type bulldozer working device. Background technique [0002] The tire-type bulldozer is an engineering vehicle with a large metal blade installed in front. When in use, the blade is lowered to cut and push coal, soil, sand and stones forward. The position and angle of the blade can be adjusted to suit Shoveling, filling, and other work can also be used to remove obstacles. [0003] The current tire-type bulldozer blade is connected to one side of the boom by a telescopic tilting cylinder, and the other side is connected by a fixed-length diagonal brace, so the blade can only tilt left and right, and cannot tilt forward and backward. When the blade is controlled to descend to the working condition position, the soil cutting angle of the blade is a fixed angle, and the soil cutting angle cannot be adjusted. This installation form has the disadvantage that the driver cannot adjust th...

Problems solved by technology

[0003] The current tire-type bulldozer blade is connected to one side of the boom by a telescopic tilting cylinder, and the other side is connected by a fixed-length diagonal brace, so the blade can only tilt left and right, and cannot tilt forward and backward. When the blade is controlled to descend to the working condition position, the soil cutting angle of the blade is a fixed angle, and the soil cutting angle cannot be adjusted. This installation form has the disadvantage that the driver cannot adjust the soil cutting angle of the blade according to different working conditions. defect

Another is that the current tire-type bulldozer blade itself is not equipped with a leveling device, which cannot better level the working surface
