Description

Technical Field

[0001] The utility model relates to the field of rock splitting devices, in particular to a rock splitting device based on an excavator with a sliding and angle-adjustable structure. Background Art

[0002] Due to the increasing construction demand for static blasting solutions in mining sites and many construction sites, many static blasting methods have emerged in the market. One common method is the hydraulic cylinder splitter. Currently, the hydraulic cylinder splitter is used by fixing the cylinder with a steel wire rope and hanging it in front of the excavator's forearm. It relies on manual labor to straighten the cylinder, align it with a pre-drilled hole, and insert it to split the ore. There are two drawbacks to this method: First, since the splitting cylinder is heavy, it is difficult to insert it into a non-vertically downward hole by relying solely on manual pushing, resulting in high labor costs. In many cases, the drilled holes are not always vertical, and some constructions have requirements for the cracking direction and angle of the rock, which are difficult to achieve with the hoisting type splitter. Second, when using the hoisting type splitter during construction, in addition to the main operator, another assistant is required to align the holes and rotate the cylinder to ensure that the cracking direction faces the free face. For the assistant, aligning the holes and rotating the cylinder will consume a large amount of physical strength and result in high labor intensity. Therefore, a rock splitting device based on an excavator with a sliding and angle-adjustable structure is needed. Summary of the Utility Model
