[0002] In open-pit mines, drilling is conducted to explore the geological composition of the area. Drilling equipment is a commonly used auxiliary device in geotechnical exploration. Existing open-pit mine borehole drilling equipment requires changing drill bits according to different geological conditions. Furthermore, when drill bits wear out and need to be disassembled, reassembled, and replaced, the process is inconvenient, time-consuming, and labor-intensive, easily affecting work efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an open-pit mine borehole drilling device that facilitates quick replacement and maintenance of drill bits according to different geological conditions, thereby improving work efficiency and solving the problems existing in the background technology.

The first drilling frame and the second drilling frame are respectively fixed on the movable frame. A first drill shaft is rotatably mounted on the first drilling frame, and a second drill shaft is rotatably mounted on the second drilling frame. The first drill shaft and the second drill shaft are respectively driven by a drilling motor.

[0006] The drilling motor is fixed on the moving frame, and a drive sleeve is fixed on the transmission shaft of the drilling motor. The moving frame is provided with a positioning groove. A guide block is fixedly connected to the first drilling frame. The guide block is slidably installed on the positioning groove. A mounting seat is slidably installed inside the first drilling frame. The first drilling shaft is rotatably connected to the mounting seat. The second drilling shaft and the second drilling frame have the same installation structure as the first drilling shaft and the first drilling frame.

[0007] A set of connecting plates is fixedly installed at both ends of the top of the mounting base. A set of sliding holes is opened on the connecting plates. Sliding rods are fixedly installed at the left and right ends of the interior of the first drill frame. The sliding holes of the connecting plates at both ends of the top of the mounting base are slidably installed on the sliding rods at the left and right ends of the first drill frame.

[0008] Elastic elements are respectively fitted onto the sliding rods at the left and right ends inside the first drill frame, and the top of the elastic elements is in contact with the bottom surface of the connecting plate on the mounting base.

[0009] A limiting rotating shaft is fixedly installed on the top of the first drill spindle. A rotating groove is opened inside the mounting base, and the limiting rotating shaft on the top of the first drill spindle is rotatably installed on the rotating groove opened inside the mounting base.

[0034] The specific method of using this utility model is as follows:

[0035] When using this open-pit blast hole drilling device, the drill bit needs to be changed according to different geological conditions. When the drill bit is worn out and needs disassembly, maintenance, and replacement, the first drill shaft 301 is pulled downwards, causing the mounting base 303 to move downwards. This slides the guide block 302 at the top of the first drill frame 3 onto the positioning groove 204 at the bottom of the moving frame 2. After the first drill frame 3 moves to the fixed position, the first drill shaft 301 is released. Under the action of the elastic element 3041 on the slide rod 304, the spline shaft 3012 at the top of the first drill shaft 301 is engaged and installed on the connecting groove 2012 at the bottom of the drive sleeve 2011. The drilling motor 201 drives the first drill shaft 301 through the drive sleeve 2011. A drill shaft 301 performs drilling operations. The drive motor 1031 drives the drive screw 103 to rotate, thereby driving the movable frame 2 and the first drill shaft 301, which are threaded onto the drive screw 103, to move downwards to drill the ground of the mining area. Similarly, the second drill frame 4 is slidably installed on the installation guide groove 105. After pulling the first drill shaft 301 downwards, the first drill frame 3 is moved to the disassembly guide groove 106. The second drill frame 4 is installed on the positioning groove 204. The second drill shaft 401 inside the second drill frame 4 is pushed to connect with the drive sleeve 2011 on the drilling motor 201, so that the device can quickly replace the drill bit and has better work and maintenance efficiency.
