Description

Technical Field

[0001] The utility model relates to the technical field of metering equipment, in particular to an explosive filling metering device. Background Art

[0002] With the improvement of engineering technology in my country, engineering blasting technology has developed rapidly in water conservancy, railway, mining and other projects. In the process of open-pit blasting, the crushing quality of rock and the unit consumption of explosives are important indicators affecting the blasting quality. In the process of drilling and blasting, sometimes there will be a lot of water inside the drilled blasthole, and ammonium oil explosive is a non-waterproof explosive, which will fail when it encounters water. If emulsion explosives are used, the cost of charging will be too high. According to statistics, the price of each ton of ammonium oil explosive is about 3,000 yuan lower than that of each ton of emulsion explosive. In some mining industries, the blasting cost of water-containing blastholes accounts for more than 55% of the total cost, and the blasting cost is higher as the mining depth decreases year by year. At the same time, the mining industry is facing fierce market competition, and the blasting cost problem has become a restrictive factor that plagues the mining workshop and even the completion of the production and operation of the entire mine. At the same time, when emulsion explosives are used for charging, sometimes the medicine rolls are not compacted, resulting in poor contact or being blocked by mud and sand to cause explosion refusal.

[0003] The traditional filling and metering device only relies on the switch valve to control the opening and closing of the discharge port. It cannot screen the filled materials, nor can it adjust the speed and falling position of the falling materials in the fixed hopper, which makes the operation difficult. Utility Model Content

[0026] The use of the utility model:

[0027] First of all, it should be made clear that the metering device involved in the utility model is mainly used for automatic screening and feeding of powder or granular materials. The utility model takes the filling of explosives as an example to explain its method of use in detail. When it is necessary to fill and feed the explosives, the output rod of the telescopic push rod 322 is started to retract to move the screening plate 313 to the bottom of the discharge port to realize the screening and filling operation of the material. After the filling is completed, the output rod of the telescopic push rod 322 is started to extend.
