Bulldozer and bulldozer universal shovel mechanism

Abstract

The invention discloses a bulldozer universal shovel mechanism which comprises a universal shovel, a bow frame, a rotating oil cylinder, a lifting oil cylinder and a regulating strut, wherein the bow frame is in ball connection with the universal shovel; the rotating oil cylinder is respectively in ball connection with the universal shovel and the bow frame; the lifting oil cylinder is respectively hinged with the bow frame and a frame of a bulldozer; and the regulating strut is respectively in ball connection with the bow frame and the universal shovel and has an adjustable axial length. After the bulldozer universal shovel mechanism provided by the invention is adopted, the lifting and descending action of a shovel blade mechanism can be realized by controlling an extension length of an oil cylinder rod of the rotating oil cylinder, the rotating action of the shovel blade mechanism can be realized by controlling an extension length of an oil cylinder rod of the rotating oil cylinder, so the universal shovel can be ensured to complete the lifting, descending and rotating motion; and a penetrating angle of the universal shovel is regulated by regulating an extension length of the regulating strut, so that a driver can conveniently regulate the penetrating angle of a dozer blade according to different working conditions. The invention also discloses the bulldozer with the bulldozer universal shovel mechanism.

Description

technical field [0001] The invention relates to the technical field of bulldozers, in particular to a bulldozer and a universal blade mechanism of the bulldozer. Background technique [0002] A bulldozer is an engineering vehicle with a large metal bulldozer blade installed in front. When in use, the bulldozer blade is lowered to cut and push mud, sand and stones forward. The position and angle of the bulldozer blade can be adjusted to suit the shovel It can also be used to remove obstacles, such as soil, filling, etc. [0003] The lifting cylinder of the traditional bulldozer universal shovel can realize the lifting action of the universal shovel, while the tilting cylinder on the bow frame realizes the universal shovel tilting action, and the rotary cylinder on the bow frame realizes the universal shovel turning action, that is, the bulldozer universal The rotary action of the shovel is completed by the telescopic movement of the rotary cylinders (two) connected to the bo...

AI Technical Summary

Problems solved by technology

[0004] But the universal shovel of the bulldozer produced at present is connected by a fixed-length connecting rod between the lower part of the universal shovel and the bow frame. It is a fixed angle, and the entry angle cannot be adjusted. This installation has the defect that the driver cannot adjust the entry angle of the bulldozing blade according to different working conditions.
