AI Technical Summary
When existing mine spray fans are idle, they are prone to blockage due to external gravel entering the inside of the spray cannon barrel, which affects normal use. The water droplets during spraying are difficult to effectively collect, resulting in splashing problems.
A mine spray fan is designed. By installing sleeves and movable blocks on the side wall of the spray fan housing, the sealing mask is driven quickly to the outside of the spray gun barrel to form a seal to prevent gravel from entering, and by rotating the base and turning it. The rod drives the sealing mask to collect dripping liquid, and combines the coordination of the limit rod and spring to achieve rapid insertion and release of limits, improving the convenience of use.
It effectively avoids the blockage of the spray gun barrel, ensures the normal use of the equipment, and reduces splashing through the sealing ring and design structure, improving the stability and convenience of the equipment.

Description
Technical Field
[0001] The utility model relates to the technical field of mine demisting, in particular to a mine spray fan. Background Art
[0002] A large amount of dust will be generated during the mining process. The flying dust will diffuse in the air and easily accumulate on the mining equipment, causing damage to the equipment. If workers inhale dust for a long time at work, it is easy to cause lung and tracheal diseases and endanger their health. The mining spray fan is a machine used in mining that suppresses dust splash by spraying water mist to condense the dust. It can effectively suppress dust and purify the air. The existing mining spray fans can basically meet daily use needs, but there are still some shortcomings that need to be improved.
[0003] Most of the mine spray fans widely used on the market are moved into the mine cave by means of external hanging, and then the liquid inside is atomized and sprayed out through the spray barrel. However, in actual use, when the spray fan is idle, the gravel on the top of the mine cave is easy to enter the external spray barrel, causing the spray barrel to be blocked and unable to be used normally. It takes a lot of time to clean. For this reason, we propose a mine spray fan to solve the above problem. Utility Model Content
