Description

Technical Field

[0001] The utility model relates to the technical field of rock drills, in particular to a rock drill capable of preventing stone fragments from splashing. Background Art

[0002] A rock drill is a tool used to directly mine stone. It drills holes in the rock strata so that explosives can be placed in to blast the rock, thereby completing the mining of stone or other stone projects. During road construction, the rock drill can also be used as a crusher to break hard layers such as concrete.

[0003] When the rock drill is working, it will continuously impact the rock layer due to the high-frequency reciprocating motion. Under the action of the impact force, it is very easy to produce a large amount of splashing gravel, which is not only very easy to cause harm to the construction workers, but also cause certain damage to the surface of the rock drill. For this reason, we provide a rock drill that can prevent the splashing of gravel. Utility Model Content

[0004] In view of the disadvantage that the existing rock drills are very likely to generate a large amount of flying gravel when continuously impacting the rock formation, which is not only very likely to cause harm to the construction workers, the utility model provides a rock drill that can prevent the flying gravel from splashing, which has the advantage of shielding the construction workers with a protective cover, thereby avoiding the flying gravel from causing harm to the construction workers, and solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A rock drill for preventing stone chips from splashing comprises a mounting shell, a hydraulic driving rod is mounted in the mounting shell, a connecting seat is connected to the bottom of the hydraulic driving rod, a chisel head is mounted to the bottom of the connecting seat, an annular seat is clamped on the outer wall of the mounting shell, an opening is arranged on the annular seat, and the opening is fixed by a locking mechanism;

[0007] A slide groove is provided on the outer wall of the annular seat, an arc-shaped slider is slidably connected in the slide groove, and a protective cover is fixedly connected to the outer wall of the arc-shaped slider, and the protective cover is an arc-shaped cover with the top bent upward.

[0008] Optionally, the locking mechanism includes side plates symmetrically arranged at the opening and fixedly connected to the annular seat, and the side of the side plates away from the annular seat is provided with a limiting opening, and a fixed seat is symmetrically connected along the limiting opening on the outer wall of one of the side plates;

[0009] A connecting nut is rotatably connected between the fixing seats, a screw rod is connected to the inner thread of the connecting nut, the diameter of the screw rod is smaller than the width of the limiting opening, and the limiting seat is coaxially connected to one end of the screw rod away from the connecting nut.

[0010] Optionally, an anti-slip pad is fixedly connected to the inner wall of the annular seat.

[0011] Optionally, a window is provided on the top of the protective cover, and a transparent plate is installed in the window.

[0012] Optionally, a baffle is fixedly connected to the bottom of the protective cover along the edge.

[0013] Optionally, a handle is fixedly connected to the outer wall of the mounting shell.

[0014] Compared with the prior art, the utility model rotates the protective cover and accurately determines the processing position through the set window, so that the splashing gravel generated by the processing can be blocked by the protective cover, thereby protecting the construction workers. At the same time, the utility model has a simple structure and is easy to install and disassemble, which improves the practicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a rock drill for preventing stone splashing, comprising a mounting shell 3, a hydraulic drive rod 5 is mounted in the mounting shell 3, a connecting seat 17 is connected to the bottom of the hydraulic drive rod 5, and a chisel head 8 is mounted at the bottom of the connecting seat 17, such as Figure 1As shown, a handle 4 is fixedly connected to the outer wall of the mounting shell 3, which is convenient for the user to hold the device and fix the device when using it. An annular seat 9 is clamped on the outer wall of the mounting shell 3. In order to increase the contact friction between the annular seat 9 and the mounting shell 3, an anti-slip pad 16 is fixedly connected to the inner wall of the annular seat 9 to prevent the annular seat 9 from falling off from the mounting shell 3 due to long-term vibration during use.

[0022] like Figure 4 As shown, in order to further improve the stability of the installation of the annular seat 9, an opening is provided on the annular seat 9, and the opening is fixed by a locking mechanism. The locking mechanism includes a side plate 6 symmetrically arranged at the opening and fixedly connected to the annular seat 9. A limiting opening 12 is provided on the side of the side plate 6 away from the annular seat 9, and a fixing seat 15 is symmetrically connected along the limiting opening 12 on the outer wall of one of the side plates 6. A connecting nut 13 is rotatably connected between the fixing seats 15. The connecting nut 13 is internally threaded with a screw 14. The diameter of the screw 14 is smaller than the width of the limiting opening 12, and the screw 14 is coaxially connected to the limiting seat 7 on one end away from the connecting nut 13. When in use, after the annular seat 9 is clamped on the outside of the mounting shell 3, the screw 14 is rotated and moved into the limiting opening 12. When the screw 14 is rotated, the limiting seat 7 can be driven to move to the outer wall of the side plate 6 and abut against it, so that the annular seat 9 can be tightly clamped on the mounting shell 3.

[0023] like Figure 2 , 3 As shown, a slide groove 11 is opened on the outer wall of the annular seat 9, and an arc-shaped slider 10 is slidably connected in the slide groove 11. A protective cover 2 is fixedly connected to the outer wall of the arc-shaped slider 10. The protective cover 2 is an arc-shaped cover with the top bent upward. A window 1 is provided on the top of the protective cover 2, and a transparent plate is installed in the window 1. A baffle 18 is fixedly connected along the edge of the bottom of the protective cover 2 to block the splashing gravel and prevent further splashing from causing harm to the construction workers.

[0024] To sum up, when the rock drill that prevents stone fragments from splashing is in use, the protective cover 2 is rotated to move it above the area to be processed, and the chisel head 8 is brought into contact with the processing surface, and the processing position is accurately determined through the window 1, or the chisel head 8 is first brought into contact with the processing surface, and then the protective cover 2 is rotated to just above the processing area, and the processing operation can be carried out. The splashing stone fragments generated by the processing can be blocked by the protective cover 2, thereby protecting the construction personnel.
