Bulldozer and earth-loosening device thereof

Abstract

The invention provides an earth-loosening device. The earth-loosening device comprises a connecting frame, a lifting oil cylinder and an earth-loosening tool, wherein one end of the connecting frame is used for connecting with a bulldozer body of a bulldozer in a hinged mode, and the other end of the connecting frame is provided with a tool mounting base, one of a cylinder barrel of the lifting oil cylinder and a piston rod of the lifting oil cylinder is hinged to a bulldozer body, and the other one of the cylinder barrel of the lifting oil cylinder and the piston rod of the lifting oil cylinder is hinged to the connecting frame or the tool mounting base, the earth-loosening tool is arranged on the tool mounting base, and the earth-loosening tool is rotationally arranged relative to the tool mounting base under the drive of a power source. Compared with the prior art, the earth-loosening tool is rotationally arranged relative to the tool mounting base under the drive of the power source, angular momentum produced in a rotating process is converted into cutting force of the earth-loosening tool to treat and process the ground, and with cutting force formed by tractive force of the bulldozer, the cutting force in an earth-loosening device operation process is significantly increased, the operation capacity of the earth-loosening device is improved, application range of the earth-loosening device is expanded, and work efficiency is improved. The invention further provides the bulldozer which is provided with the earth-loosening device on the basis of the earth-loosening device.

Description

technical field [0001] The invention relates to the technical field of construction machinery equipment, in particular to a bulldozer and a soil loosening device thereof. Background technique [0002] Such as figure 1 As shown, this figure is a three-dimensional structural schematic diagram of a crawler bulldozer. The loosening device 03 is a working device suspended at the rear end of the main body 01 of the bulldozer. It is matched with the bulldozer blade 02 to improve the working ability of the bulldozer. At present, the soil loosening device has been widely used in engineering construction and mining to rake and crack rock formations or hard road surfaces to replace the traditional construction method of drilling and blasting in stonework. [0003] Next, take the single tooth scarifier device as an example to introduce the specific structure of the traditional scarifier device, please refer to figure 2 , the single-tooth scarifying device 03 includes a scarifying dev...

AI Technical Summary

Problems solved by technology

[0006] In view of the above defects, the core purpose of the present invention is to provide a scarifying device to solve the problem that the scarifying device in the prior art has limited its scope of application because of its insufficient cutting force of the scarifying tool.
