Cold firework device and discharging device

Abstract

The invention relates to a cold firework device and a discharging device. The discharging device comprises a supporting frame, a hopper arranged on the supporting frame, and a blanking tray, wherein the bottom of the hopper is provided with a matching surface and a blanking port running through the matching surface and communicating with an inner cavity of the hopper; the blanking tray is rotatably arranged below the hopper around an axis, the peripheral side, facing the hopper, of the blanking tray can be attached to the matching surface, and a plurality of storage concave parts are formed inthe peripheral side of the blanking tray. In the process that the blanking tray rotates around the axis, the storage concave parts are sequentially in butt joint with the blanking port. Therefore, continuous material conveying is achieved through attachment of the rotating blanking tray and the matching surface, and a discharging structure is simplified. No gap needs to be formed between the blanking tray and the matching surface, so that materials are not likely to be left, leakage is prevented, cleaning is convenient, and the discharging device is prevented from being blocked due to dampingand caking of the materials.

Description

technical field [0001] The invention relates to the technical field of stage props, in particular to a cold pyrotechnic equipment and its unloading device. Background technique [0002] In order to enliven the stage atmosphere and decorate the stage background, people often set off cold fireworks to enhance the stage effect. Cold pyrotechnic equipment is a machine used to produce cold pyrotechnics in performing arts such as stages or bars. It uses eruptive and ignited metal powder to replace the fireworks effect, and has the characteristics of safety, environmental protection, and good viewing. Metal powder is a substitute for fireworks and gunpowder. After being ignited, it can replace the effect of fireworks, but it will not explode. It is safer and more environmentally friendly than gunpowder. [0003] The existing cold pyrotechnic equipment is provided with a conveying channel connected to the discharge port of the hopper, and a screw rod is set in the conveying channel...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to solve the problem that metal powder is easy to remain in the conveying channel of the cold pyrotechnic equipment in the prior art, and the metal powder agglomerated after being damp is likely to cause blockage of the conveying channel, resulting in the failure of the cold pyrotechnic equipment to perform flower spraying performances normally. A kind of cold pyrotechnic equipment and its unloading device that improves above-mentioned defect
