Abstract
The utility model provides a working device for a bulldozer. A connecting rod support welded to a shovel blade is connected with one end of a connecting rod through a pin, and the other end of the connecting rod is connected with one end of a transition support through a pin. The other end of the transition support is connected to an installation position of the lower portion of a lifting support through a pin. An installation position of the upper portion of the lifting support is connected with one end of a lifting oil cylinder through a pin. The other end of the lifting oil cylinder is connected with an installation position of the middle top portion of the transition support through a pin. The lifting support is installed on a machine frame through a fastening piece. According to the working device, the structural form and the installation mode of a traditional oil cylinder are changed, the lifting oil cylinder is installed on the lifting support, the installation strength of the lifting oil cylinder is improved, and the use performance of the whole bulldozer is effectively improved. Moreover, the working device for the bulldozer is simple in structure and convenient to disassemble, the requirement for the strength of a front engine cover and the front end of the machine frame is low, and the manufacturing cost of the whole bulldozer is lowered.
Description
Technical field
The utility model relates to a kind of equipment of scrapers vehicle, embodies especially a kind of bulldozer working device.
Background technology
In the bulldozer working device structure that we use at present, lift cylinder one end is arranged on front hood, the other end of lift cylinder is arranged on perching knife, the mounting means of this lift cylinder requires very high to the structural strength of front hood and frame front end, increase complete machine manufacturing cost, and the equipment perching knife structure of this structure is roomy, often occur that at operation in narrow space collision causes lift cylinder support ring to occur fracture, the phenomenons such as oil cylinder leakage of oil.
Summary of the invention
The purpose of this utility model is to provide a kind of bulldozer working device, change traditional lift cylinder form of structure and mounting means, solve the problem that current bulldozer working device in use occurs, effectively improve bulldozer complete machine functional performance, reduce the requirement of strength to front hood and frame front end, reduce the manufacturing cost of complete machine.
The purpose of this utility model realizes as follows: it relates to frame and perching knife, the connecting rod rack being welded on perching knife is connected with connecting rod one end by pin, the other end of connecting rod is connected with transition bracket one end by pin, the other end of transition bracket is connected with the installation site of lifting bracket bottom by pin, the installation site on lifting bracket top is connected with one end of lift cylinder by pin, the other end of lift cylinder is connected with installation site, transition bracket middle and upper part by pin, lifting bracket is arranged in frame by securing member, lift cylinder is to perching knife lifting effect.
The handspike bearing of bottom, perching knife left and right sides welding is connected with left and right push rod front end by pin, and left and right putting back-end is connected with gudgeon by securing member, and left and right sides gudgeon is arranged on chassis by securing member again; One end of dump ram is arranged on dump ram bearing by securing member, the other end of dump ram is arranged on dump ram support by pin, one end that angle modulation is supported is arranged in angle modulation support carriers by securing member, and the other end that angle modulation is supported is arranged on angle modulation supporting bracket by pin.Dump ram plays inclination angle modulation effect to perching knife, and angle modulation is supported perching knife is play and supported and angle modulation effect.
The utility model has changed traditional lift cylinder form of structure and mounting means, and lift cylinder is arranged on lifting bracket, has improved lift cylinder installation strength, has effectively improved bulldozer complete machine functional performance; And equipment mounting means of the present utility model is simple in structure, convenient disassembly, not high to the requirement of strength of front hood and frame front end, reduce the manufacturing cost of complete machine.
