Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic rock drills, in particular to a hydraulic rock drill. Background Art

[0002] When greening bare rocks caused by geological disasters, it is necessary to first crush the exposed rocks, and then restore the land by spraying a mineral-rich repair solution (such as liquid organic fertilizer), so as to facilitate the later planting of green plants to improve the environment and achieve greening. A hydraulic rock drill is a device used to crush exposed rocks. A rock drill is an important tool for drilling rocks in mines, tunnels, buildings, and road construction. A handheld hydraulic rock drill has a small impact energy and can be used to replace traditional pneumatic picks for rock drilling construction.

[0003] After searching, the existing Chinese patent with publication number CN202122116323.5 discloses a hydraulic rock drill with a dust blowing function. Through the collection structure, the collection box and the servo motor in the collection structure, and the cooperation between the air guide wheel and the air intake plate in the air guide structure, the dust generated by the air blowing and dust removal can be well adsorbed during the working air blowing and dust removal process, thereby avoiding the occurrence of problems such as dust scattering during the dust blowing process and causing a poor working environment. The dust generated in the suction can be easily filtered and cleaned by the filter box plugged and installed on the collection box.

[0004] The above technical solution has the following defects. Although such a hydraulic rock drill structure can collect and process the dust generated by rock drilling through the suction plate and the air guide wheel, thereby protecting the use environment and the health of the staff, in actual use, the dust is only collected and processed by the air guide and dust suction structures on both sides, and some dust will still not be collected in time. In order to further reduce the dust generated during the use of the hydraulic rock drill, a hydraulic rock drill is proposed, which is provided with a retractable support cover, which can wrap the rock drilling area, reduce dust splashing, and can absorb and collect the generated dust, thereby further protecting the staff and the health of the staff.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.
