[0028] The working principle of the dust prevention device installed on the conveyor for the grain depot provided by the utility model is as follows:

[0029] The first step: when conveying grain, start the exhaust fan 6, and extract the dust generated by discharging grain in the discharge pipe 3 through the cooperation of the telescopic hose 7, the exhaust pipe 8 and the installation pipe 9, so as to achieve the dust reduction effect. At the same time, under the action of the blocking component, the grain can be blocked to prevent the grain from being sucked away together with the dust. The servo motor 13 is started, and the output shaft of the servo motor 13 drives the rotating rod 14 to rotate, and the rotating rod 14 drives the cleaning frame 15 and the cleaning brush 16 to rotate, and then the cleaning frame 15 and the cleaning brush 16 can cooperate to clean the surface of the filter blocking plate 11, so as to avoid the clogging problem of the filter blocking plate 11, thereby ensuring the dust extraction and dust removal effect;

[0030] The second step: before transporting the grain, it is necessary to ensure that there is water stored in the water storage space, and the water is drained into the water storage space through the cooperation of the water pump 26, the water pumping pipe and the drainage pipe until it is detected by the liquid level sensor 27 above, and then the liquid level sensor 27 transmits the information to the controller 28, thereby closing the drainage. At the same time, the extracted dust can be discharged into the water storage space through the exhaust pipe 10 and contact and mix with the water in the water storage space, so that the dust particles are captured by the water to achieve the dust removal effect. The dust-removed gas can enter the filter space through the vent 18, and then pass through the filter screen 19 and the filter screen 20 for dust removal and filtration again, and finally discharged through the air outlet 25;

[0031] The third step: start the servo motor 24, and drive the rotating rod 21 to rotate through the output shaft of the servo motor 24, and then drive the two cleaning frames 22 and the two sets of cleaning brushes 23 to rotate through the rotating rod 21, so as to clean the surface of the filter 19 and the filter 20, thereby avoiding the clogging problem of the filter 19 and the filter 20, thereby ensuring the dust removal effect.
