The following problems exist in this technical solution:

[0004] In the existing coal mining, the electric hammer is only convenient for mining in the horizontal direction and is not easy to adjust. As a result, when mining in areas with arcs or different angles, the electric hammer cannot achieve the mining effect, which reduces the scope of application and effect.

[0005] In view of the above problems, the utility model document proposes a mining device for preventing ore splashing. Utility Model Content

[0007] The utility model provides the following technical solutions:

[0008] A mining device for preventing ore splashing, comprising:

[0009] A bottom plate, a support block is fixedly arranged on the top side of the bottom plate, a moving groove is opened on one side of the support block, a threaded block is slidably connected inside the moving groove, a moving plate is fixedly arranged on one side of the threaded block, and a plurality of electric hammers are arranged on one side of the moving plate;

[0010] An adjustment mechanism, which is arranged on the movable plate and is used to adjust the angle of the electric hammer;

[0011] The anti-splash mechanism is arranged on one side of the moving plate to prevent the ore from splashing during the mining process.

[0012] In a possible design, the adjustment mechanism includes a fixed frame, which is fixedly arranged on one side of the movable plate. A rotating block is rotatably connected between the two sides of the inner wall of the fixed frame via a rotating shaft. An electric hammer fixing block is fixedly arranged on one side of the rotating block, and multiple electric hammers are arranged on one side of the electric hammer fixing block.

[0013] In a possible design, a hydraulic cylinder and two telescopic rods are respectively arranged between the movable plate and the electric hammer fixed block, the mounting portion of the hydraulic cylinder is hinged to one side of the movable plate, the output portion of the hydraulic cylinder is hinged to one side of the electric hammer fixed block, and both ends of each telescopic rod are respectively hinged to one side of the movable plate and one side of the electric hammer fixed block.

[0014] In a possible design, the anti-splash mechanism includes a shield, the inner wall of which is provided with through grooves on all four sides, a metal retaining net is fixedly installed on the inner wall of each through groove, an insertion frame is fixedly provided on one side of the shield, a slot for inserting the insertion frame is provided on one side of the electric hammer fixing block, two locking screws are respectively penetrated on both sides of the electric hammer fixing block, and two threaded holes for threaded connection of the locking screws are respectively provided on both sides of the insertion frame.

This is helpful to prevent the electric hammer from only mining in the horizontal direction during coal mining, and is convenient for adjusting to a suitable angle position, avoiding the electric hammer from being unable to achieve mining when mining in areas with arcs or different angles, thereby improving the scope of application and effect. Then, the electric hammer can be used to mine. Mining work is carried out, and the electric hammer will be driven by the electric hammer hydraulic cylinder. The electric hammer hydraulic cylinder is installed inside the electric hammer fixed block (not shown in the figure). During the mining process, the protective cover can prevent the ore from splashing, so as to avoid the splashing ore from injuring the operator, thereby enhancing safety. The protective cover is inserted into the slot of the electric hammer fixed block through the plug-in frame and is fixed by the cooperation of the locking screw and the threaded hole, thereby achieving the effect of convenient installation and disassembly. Through grooves are opened on the four sides of the inner wall of the protective cover. The metal retaining net installed in the through groove can not only prevent the ore from splashing, but also ensure the working effect of the electric hammer, thereby improving applicability.
