Abstract

The embodiment of the invention discloses an inclined connecting rod structure of a front working device of a bulldozer, used for improving lateral stability, conveniently arranging a lift cylinder, conveniently carrying out scraping and moving control as well as improving scraping and moving penetrating power with a simple structure and low process cost when the conditions for a scraper knife to do lifting and inclining motion are met. The inclined connecting rod structure of the front working device of the bulldozer disclosed by the embodiment comprises a scraper knife, an inclined support, a left push rod, a right push rod, a lift cylinder, a rack and an inclined cylinder and also comprises an inclined connecting rod, wherein one end of the right push rod is movably connected with a first corner of the back of the scraper knife, one point at the middle part of the right push rod is connected with a second corner of the back of the scraper knife by virtue of the inclined support; one end of the left push rod is movably connected with a third corner of the back of the scraper knife, one point at the middle part of the left push rod is connected with a fourth corner of the back of the scraper knife by virtue of the inclined cylinder; and one end of the inclined connecting rod is connected with the back of the scraper knife, and the other end of the inclined connecting rod is connected with the rack.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an oblique connecting rod structure of a front working device of a bulldozer. Background technique [0002] The bulldozer blade of prior art usually adopts such as figure 1 The shown double support structure of the front working device of the bulldozer includes a lifting cylinder 10, a cutter head 11, an oblique support 12, a push rod 13, a support rod 14, a tilt cylinder 15 and a trunnion 16, wherein the support rod 14, the push rod 13 and the cutter A triangular structure is formed between the heads 11 so that the distance between the cutter head 11 and the main machine is relatively long, and the lateral stability is poor. The arrangement of the connection position of the lifting cylinder 10 on the cutter head 11 must be limited by avoiding the position of the support rod 14 on the cutter head 11, so that the arrangement of the lifting cylinder 10 deviates from the vertic...
