Description

Technical Field

[0001] This application relates to the field of blasting operation technology, specifically to a rapid loading device for explosives used in mining blasting. Background Technology

[0002] Ammonium nitrate explosives, ammonium nitrate fuel oil explosives, and black powder can all be classified as powdered explosives. These explosives have certain applications in mining blasting operations. The selection of explosives for mining blasting requires comprehensive consideration of factors such as specific blasting conditions, ore properties, safety requirements, and economic benefits. When selecting explosives, it is essential to ensure that the explosives have sufficient explosive power while meeting safety, environmental protection, and economic requirements.

[0003] An existing patent (publication number: CN212778918U) discloses an explosive filling device for blasting operations, including a protective shell, a nozzle disposed at one end of the protective shell, a sealing cover plate disposed at the other end of the protective shell, a fixing block disposed on the outer periphery of the sealing cover plate, a push block disposed inside the protective shell, a push rod connected to the push block, a connecting rod connected to the push rod, a pressure block disposed at the other end of the connecting rod, and a first connecting hole uniformly disposed on the pressure block. The pressure block is connected to a hydraulic drive device. The protective shell is used to store explosives, and the outer periphery of the protective shell is provided with scale lines. This utility model discloses an explosive filling device for blasting operations. The hydraulic drive device drives the pressure block and the connecting rod, which in turn drives the push rod via the connecting rod, which in turn pushes the explosives inside the protective shell via the push block, and thus facilitates the quantitative filling of explosives through the nozzle.

[0004] The aforementioned filling device can only fill emulsion explosives and is not applicable to granular explosives, resulting in low applicability. Furthermore, during the filling process, the filling amount can only be judged by visually observing the scale lines, leading to low filling accuracy. Utility Model Content

The two flared plates 4 have serrated grooves on the sides that are far apart from each other, which can increase the friction coefficient with the container and improve the fixing stability.

[0033] Please see Figure 1 , Figure 2 and Figure 3 The top end of the filling tube 1 is fixedly connected to a funnel 5. The inner wall of the top end of the funnel 5 is fixedly connected to a fixing frame 6. The bottom of the fixing frame 6 is rotatably connected to a filling shaft 7. The filling shaft 7, the funnel 5, and the filling tube 1 are on the same axis. The outer surface of the filling shaft 7 is fixedly connected to a screw conveyor 8. The screw conveyor 8 is located inside the filling tube 1. With the above configuration, the purpose of continuously filling powder and emulsion explosives can be achieved.

[0034] Please see Figure 1 , Figure 2 and Figure 3A motor 12 is fixedly installed on the upper surface of the fixed frame 6. The output end of the motor 12 is fixedly connected to the top end of the filling shaft 7. The motor 12 provides power for the rotation of the filling shaft 7. A micro-processing display 11 is fixedly installed on the outer surface of the funnel 5. The micro-processing display 11 allows the user to intuitively observe the filling amount. The funnel 5, filling tube 1, auger plate 8 and filling shaft 7 are all made of engineering plastic. Their excellent corrosion resistance and lightweight properties ensure that the equipment is not prone to chemical reaction when in contact with explosives, ensuring operational safety. At the same time, it reduces the weight of the equipment, making it easy to carry and operate.

[0035] This embodiment of a rapid filling device for explosives used in mining blasting, through the design of the flared ring 2 and flared plate 4, can firmly fix the filling bag and filling container. It is not only suitable for filling emulsion explosives, but also can achieve rapid and accurate filling of powder explosives, greatly expanding the applicability of the device and enabling it to meet the needs of different mining blasting operations. Through the set tension sensor 10 and micro-processing display 11, the weight of the filled explosives can be monitored in real time and the filling amount can be displayed intuitively, reducing the problem of insufficient or excessive filling caused by human judgment error, thereby ensuring the safety and effectiveness of blasting operations. The funnel 5, filling tube 1, auger plate 8 and filling shaft 7 are all made of engineering plastic material, which has excellent corrosion resistance and lightweight characteristics, ensuring that the device is not prone to chemical reaction when in contact with explosives, ensuring operational safety. At the same time, the lightweight characteristics also make the device easy to carry.

[0036] It should be noted that the rapid explosive loading equipment of this application was designed with full consideration of the complexity of the mining environment and the special requirements of blasting operations. The equipment is made of robust and durable materials and can withstand high-intensity use in harsh environments. When using this rapid explosive loading equipment, please ensure that the operator has fully understood and followed all safety operating procedures. Before each use, please check the integrity of the equipment, especially key components such as the flaring ring, connecting rod, and tension sensor, and ensure that they are in good condition. When filling explosives, be sure to keep the equipment stable and avoid shaking or tilting to prevent explosive leakage. At the same time, the operator should wear appropriate protective equipment, such as explosion-proof clothing, gloves, and goggles, to ensure personal safety. After use, please clean the equipment in time and store it in a dry, well-ventilated place to maintain the optimal performance of the equipment.

[0037] The working principle of the above embodiment is as follows: The operator first places the filling bag or filling container on the bottom end of the filling tube 1. Then, by pinching the two buckles 13, the operator brings them closer together. At this time, the two connecting rods 3 and the flaring plate 4 flip outwards. The flaring plate 4 tightly adheres to and fixes the mouth of the filling bag or container to ensure filling stability. The operator starts the motor 12 on the fixing frame 6. The output end of the motor 12 drives the filling shaft 7 to start rotating. The auger plate 8 fixed on the filling shaft 7 rotates inside the filling tube 1, forming a spiral conveying effect. The operator pours the explosive into the funnel 5. The explosive flows along the inner wall of the funnel 5. The explosive is fed into the filling tube 1. Under the spiral conveying action of the auger plate 8, the explosive is pushed evenly and continuously to the bottom of the filling tube 1 and filled into the filling bag or container. As the weight of the container increases, the container exerts a downward pulling force on the flared plate 4. The weight of the material inside the container can be monitored by the tension sensor 10, and the weight data is transmitted to the micro-processing display 11. The display shows the current filling amount intuitively, so that the operator can keep track of the filling progress at any time. When the filling amount displayed on the display reaches the preset value, the motor 12 can be automatically shut off. Then, the two buckles 13 can be released to release the container.
