Description
Technical Field
The utility model relates to an experimental apparatus, concretely relates to dust generating device of mine underground environment experiment platform.
Background
With the development of intelligent robots and robot visual monitoring, robots moving on rails are adopted for monitoring in many places, due to the fact that environmental dust is serious, images acquired by a common camera for carrying out visual acquisition are not clear in coal mines or mining areas, an infrared imaging visual lens and a common visual lens can be used for well monitoring the robots, and in the algorithm debugging of the visual lens, due to the fact that the working site environment is unsafe, the robots are not suitable for long-time on-site tests.
Therefore, when simulating a dust environment, dust needs to be manufactured artificially, and no special device for manufacturing dust artificially exists at present.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: when simulating dust environment, need the people to make the dust, do not have the problem of the isolated plant of people for making the dust at present, the utility model provides a solve the dust generating device of a mine underground environment experiment platform of above-mentioned problem.
The utility model discloses a following technical scheme realizes:
a dust generating device of an underground mine environment experiment platform comprises a grinding machine and a negative pressure adsorption nozzle; the grinding mill comprises a dust bin; the negative pressure adsorption nozzle is positioned at the upper part in the dust bin; the opening of the negative pressure adsorption nozzle faces downwards; the opening at the top of the dust bin is provided with a cover, and the negative pressure adsorption nozzle penetrates through the cover. Grind out powder to dust storehouse through the machine of grinding, thereby adsorb the less dust of light dust through the negative pressure suction nozzle from the top, the great dust of granule will be stayed in the dust storehouse to produce the dust of simulation use, provide the experiment and use, solve when simulating the dust environment, need the artificial problem of making the isolated plant of dust, do not have the artificial dust of making at present.
Further, the grinding machine further comprises a motor, the motor is fixed to the bottom of the grinding machine, a grinding blade is arranged on a rotating shaft of the motor, and the grinding blade is located at the bottom of the dust bin.
Further, the dust bin device is provided with a grinding bin which is in a hollow cylindrical shape; the upper end of the grinding bin is closed, the lower end of the grinding bin is opened, and the grinding blade is positioned in the grinding bin; the grinding bin is made of a filter screen. Through covering a grinding bin on grinding blade for primitive granule breaks up under the high-speed rotatory striking of blade repeatedly, and the filter screen that can run out grinding bin is little to the granule, makes the dust granule little, and is similar with natural dust.
Furthermore, the diameter of the mesh of the filter screen adopted by the grinding bin is between 0.1 and 0.4 mm.
Furthermore, the opening of the negative pressure adsorption nozzle is in an inverted funnel shape.
Furthermore, a filter screen is arranged at the opening of the negative pressure adsorption nozzle. Through set up the filter screen at negative pressure adsorption nozzle opening part for the second time filters the dust, and the effect is better.
The utility model discloses have following advantage and beneficial effect:
1. the utility model discloses a grind out powder to the dust storehouse through the machine, adsorb the light dust from the top through the negative pressure suction nozzle and thus take out the less dust of granule, the great dust of granule will stay in the dust storehouse to produce the dust of simulation use, provide the experiment and use, solve when simulating the dust environment, need the artificial dust of making, there is not the problem of the professional device of artificial dust at present;
2. the utility model covers a grinding bin on the grinding blade, so that the original particles are repeatedly crushed under the high-speed rotation impact of the blade until the particles are small enough to run out of a filter screen of the grinding bin, and the dust particles are small and similar to natural dust;
3. the utility model discloses a set up the filter screen at negative pressure adsorption nozzle opening part for the second time filters the dust, and the effect is better.
