[0026] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0027] Embodiment One

[0028] As Figs. 1-3As shown, the drilling and propelling integrated blasting device provided in the embodiment mainly comprises a drilling main body and an open-close cutter head 5. The drilling main body comprises an outer shell 1 and an inner shell 2. The open-close cutter head 5 is arranged at the front end of the inner shell 2. The inner shell 2 is connected with a driving device 10. The driving device 10 can drive the inner shell 2 and the open-close cutter head 5 to rotate to realize drilling. The outer shell 1 is sleeved outside the inner shell 2. A slag discharge channel 19 is formed between the outer shell 1 and the inner shell 2. A slag discharge port 12 is further arranged on the outer shell 1. The slag discharge port 12 is communicated with the slag discharge channel 19 and is used for discharging waste slag generated in the drilling process. The open-close cutter head 5 is further connected with an open-close mechanism. The open-close mechanism is used for driving the open-close cutter head 5 to open and close. The inner shell 2 is used for placing explosives. A propelling mechanism is arranged on the inner shell 2. The propelling mechanism can propel the explosives into the drilling hole to realize blasting. Specifically, during the drilling process, the open-close cutter head 5 is in the closed state. When the drilling reaches the specified depth, the drilling is stopped. The open-close cutter head 5 is opened by the open-close mechanism. Thus, the explosives can be propelled to the bottom of the drilling hole by the propelling mechanism to realize blasting.

[0029] In the embodiment, the functions of drilling, propelling and blasting are integrated. The equipment switching and preparation time is reduced. The integrated continuous operation is realized. The blasting operation efficiency is greatly improved.

[0030] In the embodiment, the explosives are preferably liquid oxygen cartridges 3. Compared with the traditional explosives, the liquid oxygen cartridges 3 generate less harmful gas and dust after explosion and pollute the environment less. The liquid oxygen cartridges 3 can be remotely detonated by a remote control detonation device to ensure the safety of the operators.

[0031] Further, mica gaskets 4 are arranged around the liquid oxygen cartridges 3. The good insulation and high-temperature resistance of the mica gaskets 4 ensure the safety of the liquid oxygen cartridges 3 during storage and oxygen charging.

[0032] In the embodiment, the drilling and propelling integrated blasting device further comprises an oxygen charging system. The oxygen charging system is used for charging liquid oxygen into the liquid oxygen cartridges 3. The oxygen charging system comprises an oxygen storage tank 14, a pneumatic rotary joint 9, a gas conveying pipeline 8 and an oxygen charging conduit 6. One end of the gas conveying pipeline 8 is connected with the oxygen storage tank 14. The other end is connected with the oxygen charging conduit 6 through the pneumatic rotary joint 9. The oxygen charging conduit 6 extends into the liquid oxygen cartridge 3 to realize liquid oxygen charging. When the drilling reaches the predetermined depth (for example, 3m), the oxygen charging is performed at 1.5m. The oxygen charging is continuously performed while the drilling machine is used to discharge slag. The liquid oxygen is charged into the liquid oxygen cartridge 3 through the oxygen charging conduit 6. The oxygen charging conduit 6 is made of low-temperature resistant and high-strength material to ensure the safety and stability of the liquid oxygen conveying.

[0033] In the embodiment, the driving device 10 mainly comprises a motor, a speed reducer and a coupling; wherein the motor is the core power source, outputs high-speed rotation, and reduces the rotation speed and increases the torque through the speed reducer (such as a speed reduction gear box) to adapt to the load requirements of drilling; the coupling connects the output shaft of the motor and the inner shell 2 to ensure torque transmission. The driving device 10 in the embodiment is compact in structure, installed at the rear or side of the outer shell 1 of the drilling main body, avoiding interference with the slag discharge channel 19.

[0034] When the driving device 10 starts, the motor transmits power to the inner shell 2 through the speed reducer to drive it to rotate; since the open-close cutter head 5 is fixed at the front end of the inner shell 2, the open-close cutter head 5 also rotates to drill. In the drilling operation, the open-close cutter head 5 is closed to form a conical drill bit, the driving device 10 rotates to generate cutting force; waste slag is discharged through the slag discharge channel 19 and the slag discharge port 12. The driving device 10 is usually controlled by a frequency converter to adapt to different geological conditions.

[0035] In the embodiment, it needs to be pointed out that the inner shell 2 and the outer shell 1 are connected through a spiral structure 24, so that the inner shell 2 is driven to rotate by the motor, which can make the inner shell 2 and the open-close cutter head 5 move forward to realize drilling; wherein the spiral structure 24 comprises external threads arranged on the outer wall of the inner shell 2 and internal threads arranged on the inner wall of the outer shell 1, and the inner shell 2 and the outer shell 1 are threadedly connected.

[0036] Further, it needs to be pointed out that the inner wall of the rear end of the outer shell 1 is provided with a threaded segment, the threaded segment is provided with internal threads, and the threaded segment is arranged away from the slag discharge port 12 to avoid affecting slag discharge.

[0037] In the embodiment, as shown in Figs. 2-3 The open-close cutter head 5 is preferably a three-piece conical open-close cutter head, or other open-close cutter heads 5 can also be selected according to needs.

[0038] In the embodiment, the opening and closing mechanism includes an opening and closing motor 11 connected with the opening and closing cutter head 5 through a hydraulic system. The opening and closing motor 11 is started to drive the hydraulic system to open and close the opening and closing cutter head 5. The hydraulic system mainly includes an oil tank, a hydraulic pump, a control valve and a hydraulic cylinder. The opening and closing motor serves as an electric driving source, and its output shaft is connected with the hydraulic pump. When the opening and closing motor 11 is started, the hydraulic pump is driven to rotate, and hydraulic oil is sucked from the oil tank and pressurized. The high-pressure oil liquid is adjusted in direction by the control valve (such as an electromagnetic valve) and then enters the hydraulic cylinder. The piston rod of the hydraulic cylinder is connected with the linkage 7 or the hinge point of the opening and closing cutter head 5. The extension and retraction of the piston rod is directly converted into the opening and closing of the cutter head petals. When the piston rod extends, the petals are pushed to open. When the piston rod retracts, the petals are closed. The whole process is monitored by a remote control system to ensure accuracy.

[0039] Further, the pushing mechanism includes a hydraulic push rod connected with the hydraulic system. The hydraulic system can drive the hydraulic push rod to push the liquid oxygen cartridge 3.

[0040] In the embodiment, the driving device 10 is independent of the hydraulic system but is coordinated through the support platform 20 below. However, the driving device 10 is mainly arranged inside the drilling main body. The design ensures high torque output and low vibration, supporting continuous drilling to a specified depth (such as 3 m).

[0043] In the embodiment, the four corners of the support platform 20 are provided with lifting legs 15. The lifting legs 15 can accurately adjust the height of the device according to different terrains and operation requirements to ensure the perpendicularity and accuracy of drilling. The bottom of any lifting leg 15 is provided with a first pulley 16 to facilitate movement.
