Technical Field

[0001] This utility model relates to the field of mining blasting technology, and in particular to a mining blasting excavation device. Background Technology

[0002] In the mining process, blasting is an important technological means to achieve rock crushing and ore body stripping. It is widely used in the production process of open-pit and underground mines. By rationally arranging blast holes and loading explosives for detonation, the rock mass structure can be effectively destroyed, enabling efficient separation and crushing of ore. This creates favorable conditions for subsequent excavation, transportation and mineral processing operations. Blasting not only directly affects mining efficiency and cost control, but also plays an important role in mine safety production, resource utilization and environmental protection. It is one of the indispensable key technologies in modern mining engineering.

[0003] However, traditional blasting operations are mostly carried out manually or semi-mechanized, including drilling, charging, and detonation. This has problems such as high labor intensity, low efficiency, and high safety risks. Especially under complex geological conditions, manual drilling is not only time-consuming and labor-intensive, but also makes it difficult to ensure the depth and position accuracy of the boreholes, affecting the blasting effect. In addition, the explosive loading process usually adopts an open operation, lacking precise control methods, which can easily lead to uneven loading, serious waste, and even safety accidents.

[0004] Therefore, it is necessary to design a mine blasting and excavation device to solve the above-mentioned technical problems. Utility Model Content

[0008] Furthermore, it also includes transparent plates, with multiple transparent plates evenly fixed to the outer wall of the medicine container along the circumference.

[0009] Furthermore, it also includes a dual-axis motor and track wheels. The dual-axis motor is fixedly connected to the front bottom of the support plate, and the output shafts on the left and right sides of the dual-axis motor are respectively connected to track wheels.

[0010] Furthermore, it also includes a shovel, with a shovel installed at the front of the support plate.

[0011] Furthermore, it also includes a cleaning brush, which is installed on the rear side of the bottom of the support plate and is located behind the drug delivery tube.

[0012] Furthermore, it also includes an infrared transmitter, a control sensor, and a receiver. The infrared transmitter is fixedly connected to the front top of the support plate, the control sensor is fixedly connected to the rear side of the support plate, and the receiver is installed in the middle front of the medicine tank.

[0015] 3. This utility model uses a dual-axis motor to drive the tracked wheels, enabling the equipment to move flexibly and position precisely in complex terrain, effectively improving the adaptability and mobility of mining blasting operations, reducing manual handling and adjustment time, and improving overall construction efficiency.

[0016] 4. This utility model uses a depth measurement control system composed of an infrared transmitter, a receiver, and a control sensor to automatically determine whether the drilling depth meets the requirements.

[0026] Example: A mine blasting and excavation device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the device includes a support plate 1, a support frame 2, a hydraulic rod 3, a connecting plate 4, a drill rod 5, a medicine tank 9, a transparent plate 901, a valve 902, a cover plate 10, and a medicine guide tube 11. The support frame 2 is welded to the top of the support plate 1. The hydraulic rod 3 is screwed to the top of the support frame 2. The telescopic rod of the hydraulic rod 3 passes downward into the support frame 2 and is connected to the connecting plate 4. The drill rod 5 is installed at the bottom of the connecting plate 4. The medicine tank 9 is located at the rear of the support frame 2. Multiple transparent plates 901 are evenly glued to the outer wall of the medicine tank 9 along the circumference. The top of the medicine tank 9 is equipped with an openable cover plate 10. The bottom of the medicine tank 9 is connected to and communicates with the medicine guide tube 11. The valve 902 is installed on the medicine guide tube 11.

[0027] like Figure 2 and Figure 3 As shown, it also includes a sleeve 6, a connecting rod 7 and a spring 8. Sleeves 6 are symmetrically arranged on the left and right sides of the bottom of the connecting plate 4, and connecting rods 7 are arranged on the top of the support plate 1 at the positions corresponding to the sleeves 6. The connecting rods 7 are inserted into the corresponding sleeves 6 and can slide along them. Springs 8 are connected between the sleeves 6 and the corresponding connecting rods 7.

[0028] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, it also includes a dual-axis motor 12, track wheels 13, a digging shovel 14, and a cleaning brush 15. The dual-axis motor 12 is installed on the front bottom of the support plate 1 by screws. The output shafts on the left and right sides of the dual-axis motor 12 are respectively connected to the track wheels 13. The digging shovel 14 is installed on the front of the support plate 1, and the cleaning brush 15 is installed on the rear bottom of the support plate 1. The cleaning brush 15 is located behind the medicine guide tube 11.

[0029] like Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, it also includes an infrared transmitter 16, a control sensor 17, and a receiver 18. The infrared transmitter 16 is installed on the front top of the support plate 1 by screws, and the control sensor 17 is installed on the rear side of the support plate 1 by screws. The receiver 18 is installed in the front middle of the medicine tank 9. The control sensor 17 is electrically connected to the hydraulic rod 3, the dual-axis motor 12, the infrared transmitter 16, and the receiver 18, respectively.

[0030] When blasting is required in a mine, firstly, the dual-axis motor 12 is started, and its output shaft drives the two tracked wheels 13 to rotate, moving the entire machine to the target work area to achieve rapid positioning of the rock strata. At this time, the support plate 1, as the basic platform of the entire device, remains stable, and the support frame 2 is fixed on its upper part to provide structural support for subsequent operations. Then, the hydraulic rod 3 is started, and its telescopic end pushes the connecting plate 4 downward, so that the drill rod 5 is aligned with the predetermined position to start drilling. During the drilling process, the connecting rod 7 is inserted into the sleeve 6 below the connecting plate 4 and can slide along it. At the same time, the spring 8 is compressed, which plays a role in buffering the impact force, thereby improving the drilling accuracy and the stability of equipment operation. After drilling is completed, the operator opens the cover plate 10, adds explosive powder into the charging barrel 9, and closes the cover plate 10 to prevent dust leakage. Then, the control valve 902 opens the guide pipe 11, so that the explosive powder falls evenly into the drilled blast hole. The outer wall of the charging barrel 9 is equipped with multiple transparent observation plates to facilitate real-time monitoring of the charge amount and status, ensuring that the charging process is safe and controllable. Infrared transmitter 16 emits a signal, which is received by receiver 18 and fed back to control sensor 17. The system determines whether the drilling depth meets the standard based on the signal. After confirmation, it enters the detonation preparation stage. The operator retreats to a safe distance and sends a detonation command via remote control or field controller to complete the remote detonation. After the blasting is completed, the device switches to the slag removal and excavation mode. The shovel 14 starts working to excavate and concentrate the rock fragments after the blasting, improving work efficiency. At the same time, the cleaning brush 15 moves with the device to automatically remove residual dust and debris on the ground, providing a clean environment for subsequent operations and preventing residues from affecting the drilling accuracy of the next round. In the entire operation, the device realizes integrated operation from drilling, charging, detonation to slag removal. The various components work together to improve the safety, automation level and resource utilization efficiency of mining blasting operations. It is suitable for open-pit or underground mine construction scenarios in complex terrain. After the operation is completed, the hydraulic rod 3 and dual-axis motor 12 are turned off, and the equipment is ready for use. The above steps can be repeated for the next use.
