Description

Technical field:

[0001] The present application relates to the technical field of bulldozer equipment, and in particular to a quick-change structure for a bulldozer blade head. Background technology:

[0002] Bulldozers are earth-moving machines that can dig, transport and dump rock and soil. They are widely used in open-pit mines, for example, to build dumps, level dumps for cars, pile up scattered ore and rock, level work platforms and construction sites, etc.

[0003] Our company's utility model patent application number is 201920245890.0 - a blade structure and a bulldozer. The blade structure includes a main frame and a cutter head detachably mounted on the main frame. The main frame is provided with at least two groups of pin pulling cylinders and at least two first positioning parts. Each group of pin pulling cylinders is correspondingly arranged on one side of a first positioning part, and a positioning pin is fixedly connected to the output end of the pin pulling cylinder; at least two second positioning parts are symmetrically arranged on the cutter head, and each second positioning part is arranged opposite to a first positioning part. The pin pulling cylinder can drive the positioning pin to pass through the relative first positioning part and the second positioning part.

[0004] This patent utilizes a pin-pulling cylinder to drive the positioning pin to be installed in the first through hole, which requires the design of a control system and a piping system for the plug-in and pull-out cylinders, which greatly increases the cost. At the same time, due to the complex working environment of the bulldozer, it is very easy to cause damage and aging of the pipelines, resulting in a high failure rate, which seriously affects actual use.

[0009] A plugging end cover, which is arranged at the upper end of the vertical slide groove in a detachable structure;

[0010] The scraper is arranged on the outside of the mounting plate in a fixed structure manner.

[0011] Furthermore, the hanging plate includes a vertical plate, a hook in an inverted U-shaped structure is fixedly provided on one side of the upper portion of the vertical plate, a bottom plate is fixedly provided on one side of the lower portion of the vertical plate, and the bottom plate, the hook and the main frame are all connected by bolts.

[0012] Furthermore, a vertical slide groove is provided on the outer side of the vertical plate, and the lower end of the vertical slide groove is not connected to the lower end surface of the vertical plate;

[0013] The sliding block is fixedly arranged on the side elevation of the mounting plate.

[0014] Furthermore, the end surface of the vertical plate at the upper end of the vertical slide groove is connected to the sealing end cover by means of a screw engagement structure.

[0015] Furthermore, a slider is fixedly provided on the outer surface of the vertical plate;

[0016] A vertical slide groove is provided on the side surface of the mounting plate close to the vertical plate, and the end surface of the mounting plate at the upper end of the vertical slide groove is connected with the blocking end cover through a screw engagement structure.

[0017] Furthermore, the vertical slide groove and the sliding block are both arranged in a T-shaped structure.
