Abstract

The invention relates to a rock breaking device carried to an excavator, and the problems that an existing device scarifier is poor in rock entering angle, energy consumption is high, and the rock breaking effect is poor are solved. One end of a bucket rod cylinder is hinged to the upper edge of the middle portion of a big arm, and the other end of the bucket rod cylinder is hinged to the upper end of a small arm. The upper end of the small arm and one end of a scarifier oil cylinder are hinged, the other end of the scarifier oil cylinder is hinged to the upper end of the scarifier, the lowerend of the scarifier is connected with bucket teeth, and the ratio of the distance between a fourth hinge shaft and a first hinge shaft to the distance between the first hinge shaft and a seventh hinge shaft is larger than 0.8, the length of an upper part of the scarifier is larger than the distance between a fourth hinge shaft and the first hinge shaft, and when the fourth hinge shaft has multiple installing positions, the shortest distance serves as the criterion for the distances between the fourth hinge shaft and the first hinge shaft, and the length of the upper part of the scarifier is larger than the distance between the first hinge shaft and the seventh hinge shaft, and when the first hinge shaft has multiple installing positions, the shortest distance serves as the criterion for the distances between the first hinge shaft and the seventh hinge shaft, the total length of the scarifier is larger than the distance between the fourth hinge shaft and the seventh hinge shaft, and when the fourth hinge shaft has multiple installing positions, the shortest distance serves as the criterion for the distances between the fourth hinge shaft and the seventh hinge shaft.

Description

technical field

[0001] The present invention relates to a rock breaking device mounted on an excavator. Background technique

[0002] In rock formation mining construction operations, for rock formations that are not very hard, the construction method of carrying a ripper on an excavator is widely used because of its good construction effect. For this construction method, the prior art works on the boom, forearm and ripper Many optimizations and improvements have been made to improve the use effect.

[0003] Here the device made up of boom, forearm, ripper and oil cylinder is called rock breaking device. The existing rock-breaking device improves the rock-breaking ability by changing the torque of the forearm and increasing the weight of the boom and forearm. The ratio of the distance between the connecting point of the arm and the connecting point of the small arm and the large arm to the connecting point of the small arm and the ripper is 0.4-0.8. In the actual use of t...
