Description

Technical Field

[0001] The utility model belongs to the technical field of drilling machines, in particular to a drilling machine for open-pit mining which is easy to adjust. Background Art

[0002] Open-pit mining is the process of removing the covering from an ore body to obtain the desired mineral. Open-pit mining can be categorized into open-pit metal ore mining, open-pit coal mining, and open-pit iron ore mining. The former primarily mines non-ferrous metals, the intermediate mining focuses on coal and some non-metallic minerals, and the latter primarily mines iron ore.

[0003] During the development of the present invention, the inventors discovered that this technology presents at least the following problems: Some open-pit mines require the use of drilling machines to drill and crush relatively hard ore bodies. Currently, most such drilling machines have fixed structures and can only drill from a specific angle. However, in practice, the ore body to be drilled and the location of the drilling machine are uncertain and complex, making it difficult to accurately align the drill bit with the ore body, resulting in a limited range of mining applications.

[0004] Therefore, we propose an open-pit mining drilling machine that is easy to adjust to solve the above problems. Utility Model Content

[0005] The main purpose of the present utility model is to provide an open-pit mining drilling machine that is easy to adjust. The adjustment of its drilling module is more convenient and flexible, thereby adapting to various complex open-pit mining tasks, improving the scope of application of the mining machine, and effectively solving the problems in the background technology.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A drilling machine for open-pit mining that is easy to adjust, comprising a base and a drilling module arranged on the base, positioning piers are welded on both sides of the top wall of the base, and support platforms are welded on the two positioning piers, a positioning motor is horizontally mounted on the support platform, wherein a top groove is formed through the support platform, a screw, two sliding rods symmetrical to both sides of the screw, and a horizontally sliding slide are arranged in the top groove, the output shaft of the positioning motor is coaxially connected to the screw, the two sliding rods are welded to the support platform, the slide is threadedly sleeved on the screw, and the two ends of the slide are respectively slidably sleeved on the two sliding rods;

[0008] An upper slide is welded above the slide, and hydraulic telescopic rods and rotating shafts are respectively provided on both sides of the inner cavity of the upper slide. The two ends of the hydraulic telescopic rod are respectively connected to connecting shafts, and the hydraulic telescopic rod is connected to the upper slide and the movable platform through two connecting shafts. One end of the movable platform is fixedly sleeved on the rotating shaft, the rotating shaft is horizontally arranged, and the rotating shaft is rotatably connected to the upper slide. The drilling module includes a drilling motor installed on the movable platform and a drill bit coaxially connected to the output shaft of the drilling motor. Both the positioning motor and the drilling motor require power supply from external power facilities.

[0009] As a preferred embodiment, two rollers are installed on both sides of the base, that is, there are four rollers in total and they are distributed in a rectangular array; so that the base and the drilling module thereon can move with the rolling of the four rollers.

[0010] As a preferred embodiment, the screw rod and the two slide rods are all arranged horizontally, and both ends of the screw rod are rotatably connected to the support platform; so that the positioning motor can drive the screw rod to operate stably when it is running.

[0011] As a preferred embodiment, the inner cavity of the upper slide is formed on its top wall, the hydraulic telescopic rod is arranged at an angle, and the connecting shafts at both ends of the hydraulic telescopic rod are respectively installed on the bottom wall of the inner cavity of the upper slide and the bottom wall of the movable platform; when the hydraulic telescopic rod is extended or retracted, it can drive the movable platform to flip along with the rotating shaft, thereby facilitating the adjustment of the angle of the drill bit.

[0012] As a preferred embodiment, a pad is welded to the inner cavity of the upper slide on the side where the hydraulic telescopic rod is located; when the movable platform is in a horizontal state, it abuts against the pad, thereby keeping the movable platform stable.

[0013] As a preferred embodiment, a cover is welded on the outer side of the drilling motor above the movable table; the drilling motor can be protected by the cover.

[0014] In summary, the technical effects and advantages of the utility model are:

[0015] The easily adjustable open-pit mining drilling machine drives the positioning motor to operate, thereby causing the screw to rotate and drive the drilling module forward. The angle of the drilling module can be adjusted by extending and retracting the hydraulic telescopic rod. The above two adjustments to the drilling module can be performed simultaneously, making the adjustment of the drilling module more convenient and flexible, thereby adapting to various complex open-pit mining operations and improving the applicability of the mining machine.
