[0039] In this embodiment, the front side refers to the side close to the drilling direction, and the rear side refers to the side away from the drilling direction.

[0040] like Figures 1 to 7As shown, a device for blasting and drilling ore for underground mining in a metal ore deposit includes a mobile vehicle 1, a hydraulic cylinder 101, a controller 102, a protective plate 103, a rotating shaft 104, a drill bit 105, a fastener 106, a cylinder 303, a fixing nail 304, a power assembly, and a sensing assembly. The hydraulic cylinder 101 is mounted on the top of the mobile vehicle 1. The controller 102 is mounted on the mobile vehicle 1 and located behind the hydraulic cylinder 101. The protective plate 103 is connected to the top of the mobile vehicle 1 near the front. The protective plate 103 is vertically mounted on the top of the mobile vehicle 1. The telescopic rod of the hydraulic cylinder 101 extends horizontally forward through the center of the protective plate 103 and slides with the protective plate 103. When drilling, the protective plate 103 not only blocks soil debris and dust, preventing soil debris and dust from entering the hydraulic cylinder 101 and the controller 102 behind, but also supports the telescopic rod of the hydraulic cylinder 101. The front end of the telescopic rod of the hydraulic cylinder 101 is rotatably connected to a rotating shaft 104. The rotatable connection is usually achieved by using bearings. This is a conventional technique in the art and will not be described in detail. A drill bit 105 is mounted on the front end of the rotating shaft 104 via a fastener 106. That is, the rear end of the drill bit 105 is fixedly connected to the front end of the rotating shaft 104 via the fastener 106. The rotating shaft 104 and the drill bit 105 are coaxially arranged with the telescopic rod of the hydraulic cylinder 101. A sensing component is provided on the protective plate 103. Four cylinders 303 are evenly mounted on the bottom of the mobile vehicle 1. The telescopic rods of the cylinders 303 are vertically downward. The bottoms of the telescopic rods of the cylinders 303 are all connected to fixing pins 304. The cylinders 303 and the hydraulic cylinder 101 are both electrically connected to the controller 102 and controlled by the controller 102. A plurality of universal wheels are evenly mounted on the bottom of the mobile vehicle 1. The universal wheels are made of nylon and have high wear resistance.

[0041] like Figure 6-Figure 7As shown, the sensing assembly includes a guide rail 201, a limit frame 202, an infrared receiver 301, and an infrared transmitter 302. The front side of the protective plate 103 is symmetrically connected to the guide rails 201 at the upper and lower positions. One end of the upper and lower guide rails 201 is fixed to the protective plate 103 by bolts, and the other end of the upper and lower guide rails 201 extends horizontally to the front side. The drill bit 105 is located in the middle between the upper and lower guide rails 201. The limit frame 202 is installed between the upper and lower guide rails 201 and slides with the upper and lower guide rails 201. The top end of the limit frame 202 slides with the upper guide rail 201, and the bottom end of the limit frame 202 slides with the lower guide rail 201. The limit frame 202 is located on the outside of the telescopic rod of the hydraulic cylinder 101. The middle part of the limit frame 202 is clamped and fixed to the telescopic rod of the hydraulic cylinder 101. When the telescopic rod of the hydraulic cylinder 101 is extended or retracted, the limit frame 202 is driven to move synchronously. An infrared transmitter 302 is installed at the bottom of the upper guide rail 201 near the side of the protective plate 103, and an infrared receiver 301 is installed at the top of the telescopic rod of the hydraulic cylinder 101 and below the infrared transmitter 302. The infrared transmitter 302 and the infrared receiver 301 are both electrically connected to the controller 102.

[0042] like Figure 4-Figure 5 As shown, the power assembly includes a motor 401 and a transmission assembly 402. The motor 401 is installed on the lower part of the limit frame 202 by bolts. The motor 401 is electrically connected to the controller 102. The transmission assembly 402 is installed between the output shaft of the motor 401 and the rotating shaft 104. The motor 401 drives the rotating shaft 104 to rotate through the transmission assembly 402. The transmission assembly 402 can be a driving gear, a driven gear and a sprocket. It is only necessary to install the driving gear on the output shaft of the motor 401, the driven gear on the rotating shaft 104, and the sprocket on the driving gear and the driven gear. When the motor 401 rotates, the rotating shaft 104 can be driven to rotate through the driving gear, the sprocket and the driven gear, and then the drill bit 105 can be driven to rotate. The transmission assembly 402 can also use a main pulley, a slave pulley and a belt to achieve power transmission through the cooperation of the belt and the pulley. The transmission assembly 402 is a prior art and will not be described in detail.

[0043] The metal ore deposit underground mining ore blasting drilling device also includes a buffer cleaning component, such as Figures 8-10As shown, the buffer cleaning assembly includes a sealing box 501, an airbag 502, an air inlet check valve 503, an extrusion block 504, a support frame 505, and an air pipe 506. The sealing boxes 501 are symmetrically connected to the front side of the protective plate 103, located on the left and right sides of the upper and lower guide rails 201. The two sealing boxes 501 are mounted on the protective plate 103 by bolts. The outside of each sealing box 501 is connected to an airbag 502 that communicates with the inside. That is, the left side of the left sealing box 501 is connected to an airbag 502 that communicates with the inside, and the right side of the right sealing box 501 is connected to an airbag 502 that communicates with the inside. The airbags 502 are made of rubber material and are highly elastic and durable. An air intake check valve 503 is installed on the top of each sealed box 501. A filter screen is installed at the air intake end of the air intake check valve 503 to filter out debris. The filter screen filters out debris and prevents it from entering the sealed box 501, the airbag 502, and the air pipe 506. Support frames 505 are connected between the left and right sides of the upper and lower guide rails 201. Specifically, one support frame 505 is connected to the left side of the upper and lower guide rails 201, and one support frame 505 is connected to the right side of the upper and lower guide rails 201. Both support frames 505 are located near the front ends of the upper and lower guide rails 201, and the drill bit 105 is located between the left and right support frames 505. The front sides of the sealed box 501 on the left and the sealed box 501 on the right are both provided with a plurality of air pipes 506 from top to bottom. One end of the air pipe 506 on the left is rotatably connected to the sealed box 501 on the left and communicates with the inside of the sealed box 501 on the left (i.e., one end of the air pipe 506 on the left is inserted into the sealed box 501 on the left, the outer wall of one end of the air pipe 506 on the left is rotated and sealed with the box wall of the sealed box 501 on the left, and the inside of the air pipe 506 on the left is communicated with the inside of the sealed box 501 on the left). The other end of the air pipe 506 on the left passes horizontally through the support on the left. The right air pipe 506 is rotatably connected to the right sealed box 501 and communicates with the inside of the right sealed box 501 (i.e., one end of the right air pipe 506 is inserted into the right sealed box 501, the outer wall of one end of the right air pipe 506 is rotatably and tightly engaged with the box wall of the right sealed box 501, and the inside of the right air pipe 506 is communicated with the inside of the right sealed box 501). The other end of the right air pipe 506 passes through the right support frame 505 and rotatably engages with the right support frame 505. A plurality of one-way valve nozzles for spraying gas are installed on the air pipe 506.The left and right sides of the limiting frame 202 are connected to extrusion blocks 504, one end of the left extrusion block 504 is fixed on the left side of the limiting frame 202, the other end of the left extrusion block 504 corresponds to the airbag 502 on the left and is close to the airbag 502 on the left, one end of the right extrusion block 504 is fixed on the right side of the limiting frame 202, the other end of the right extrusion block 504 corresponds to the airbag 502 on the right and is close to the airbag 502 on the right. In the initial state, the other end of the extrusion block 504 squeezes the airbag 502 on the corresponding side.

[0044] When pre-drilling a hole in a blasting area, first determine the blasting area. After determining the blasting area, push the device to the designated location through the universal wheels at the bottom of the mobile vehicle 1. After arriving at the blasting area, select a suitable drill bit 105 according to the hardness of the rock on the side wall of the mine, and fix it to the rotating shaft 104 through the fastener 106. After the preparation is completed, operate the controller 102 to start the power supply of the device, the infrared transmitter 302 starts to work and emits infrared rays, which are received by the infrared receiver 301. Then start the hydraulic cylinder 101 and the motor 401. The output shaft of the motor 401 rotates and drives the rotating shaft 104 and the drill bit 105 to start rotating through the transmission component 402. The telescopic rod of the hydraulic cylinder 101 extends, driving the rotating shaft 104 and the drill bit 105 to start rotating. 05 and the limit frame 202 move forward, the drill bit 105 gradually approaches the side wall of the mine, the limit frame 202 moves smoothly along the guide rail 201 to ensure the stability of the telescopic rod movement of the hydraulic cylinder 101, the motor 401 and the transmission assembly 402 move with the limit frame 202, the telescopic rod of the hydraulic cylinder 101 extends to drive the infrared receiver 301 to move forward, the infrared receiver 301 is staggered with the infrared transmitter 302, and no longer receives infrared rays. At this time, the infrared receiver 301 sends a signal to the controller 102, and the controller 102 starts the cylinder 303. The telescopic rod of the cylinder 303 extends to drive the fixing nail 304 to move downward until it is driven into the ground, thereby stabilizing the mobile vehicle 1, and the telescopic rod of the cylinder 303 will automatically close after extending to the limit. Initially, the extrusion block 504 squeezes the airbag 502, and the airbag 502 is deformed. However, when the extrusion block 504 moves forward together with the limit frame 202, when the extrusion block 504 breaks away from the contact with the airbag 502, the airbag 502 relies on its own elastic rebound to reset, and the external air will be drawn into the sealing box 501 and the airbag 502 through the air intake one-way valve 503. The internal air will not flow back through the air intake one-way valve 503, and the interior of the airbag 502 is in a state of full gas. When the drill bit 105 moves forward, it contacts the side wall of the mine and drills the side wall of the mine. After the hole is drilled to a predetermined depth, the operating controller 102 controls the telescopic rod of the hydraulic cylinder 101 to begin to retract, driving the rotating shaft 104 and the drill bit 105 to move backward and reset, and at the same time driving the limit frame 202 and the extrusion block 504 to move backward. The extrusion block 504 contacts the air bag 502 and squeezes the air bag 502. After being pressurized, the air bag 502 plays a buffering role to prevent the limit frame 202 from moving backward and making hard contact with the protective plate 103. At the same time, the gas inside the air bag 502 is transported to the air pipe 506 through the sealing box 501, and then sprayed from the one-way valve nozzle on the air pipe 506 to the drill bit 105, the guide rail 201 and other components, which can clean the soil dust on the drill bit 105, the guide rail 201 and other components to ensure that the drill bit 105 is clean and avoid affecting the next use.The air pipe 506 in this embodiment can be rotated and adjusted to adjust the direction of the one-way valve nozzle, which is beneficial for the one-way valve nozzle to align with the drill bit 105, the guide rail 201 and other components, and then purge the drill bit 105, the guide rail 201 and other components. The motor 401 is turned off, causing the rotating shaft 104 and the drill bit 105 to stop rotating. The telescopic rod of the hydraulic cylinder 101 drives the rotating shaft 104, the drill bit 105, and the limit frame 202 to move backward and reset. At the same time, it drives the motor 401, the transmission assembly 402, and the infrared receiver 301 to move backward and reset synchronously. After resetting to the initial position, the hydraulic cylinder 101 automatically closes. The infrared receiver 301 is re-aligned with the infrared transmitter 302 and receives infrared rays. At this time, the infrared transmitter 302 sends a signal to the controller 102, which controls the telescopic rod of the cylinder 303 to retract upward and reset, driving the fixing nail 304 to move upward and clear of the ground. After resetting, the cylinder 303 automatically closes, thus completing the pre-drilling of a drilling point. The installation of the fixing nail 304 allows the vehicle 1 to be moved stably during the drilling process without manual intervention, ensuring a certain degree of safety. According to the above operation method, drilling work can be carried out on other blasting points. After the operation is completed, the power of the device is turned off.

[0047] S2: Push the device to the blasting site, operate the controller 102 to start the hydraulic cylinder 101 and the motor 401, and the telescopic rod of the hydraulic cylinder 101 extends, driving the drill bit 105 to move forward close to the mine wall. The motor 401 acts as a power source to drive the drill bit 105 to rotate.

[0048] S3: The infrared receiver 301 is separated from the infrared transmitter 302 as the telescopic rod of the hydraulic cylinder 101 moves. At this time, the controller 102 controls the cylinder 303, and the telescopic rod of the cylinder 303 extends, driving the fixing nail 304 to move downward and penetrate into the ground to stabilize the position of the mobile vehicle 1.

[0049] S4: Drilling can be carried out after the drill bit 105 approaches the mine wall. After drilling is completed, the drill bit 105 is driven to retreat and reset by the telescopic rod of the hydraulic cylinder 101. The infrared transmitter 302 and the reset infrared receiver 301 are re-sensed. The controller 102 controls the cylinder 303. The telescopic rod of the cylinder 303 retracts and drives the fixing nail 304 to reset upward.

[0050] S5: When the telescopic rod of the hydraulic cylinder 101 is reset, the airbag 502 is squeezed by the squeezing block 504. While the airbag 502 acts as a buffer, the gas inside the airbag 502 is sprayed toward the guide rail 201 and the drill bit 105 through the one-way valve nozzle on the air pipe 506, which can clean the soil dust on the guide rail 201 and the drill bit 105. Finally, the operation is completed and the power is turned off.
