Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical automation, and particularly relates to a device for automatically scraping and removing floating medicine from a perforating bullet. Background Art

[0002] In the domestic petroleum civil explosive equipment industry, perforating bullets are generally produced manually, and operators are directly in contact with the secondary explosives and main explosives. Both agents are flammable and explosive dangerous goods and have high friction and impact sensitivity, which poses a great safety hazard and threatens personal safety. Especially during the process of replenishing, adding materials and scraping, on the one hand, the floating drugs produced enter the human body through the respiratory tract and skin, endangering the health of the operators, and on the other hand, there is the possibility of friction between the scraper and the explosives during the hanging process, which poses a safety hazard.

[0003] For example, workers use quantitative medicine cups to add explosives to perforating bullets. When the explosives are added, the top of the perforating bullet needs to be piled up or the excess explosives need to be smoothed. At this time, workers will use a scraper, fix the scraper with one hand, and rotate the perforating bullet with the other hand to scrape off the excess explosives on the top, and then use a brush to collect the floating explosives together. The above process has the following disadvantages: the labor intensity is high and the operation level is inconsistent. Manual scraping and cleaning requires long-term training and accumulation of a lot of experience. Workers cannot ensure the reliable and stable rotation of the perforating bullet. The scraping effects of workers with different experience are uneven. Explosives are dangerous goods. Workers are in a relatively dangerous explosive dust environment for a long time. If the perforating bullet explodes due to misoperation or other reasons during the operation, the workers will be in danger of life.
