Referring to fig. 3, the water spraying pipe 34 is connected to an external water source pipe, an atomization nozzle is disposed on the water spraying pipe 34, and the water mist sprayed from the water spraying pipe 34 is used for degrading dust inside the dust accumulation cover 31, so as to prevent the dust from diffusing outwards through the dust accumulation cover 31, and separate processing of the dust and crushed stones is realized.
Referring to fig. 4, a plurality of screening holes 213 form a crushed stone screening area, and the crushed stone screening area is only located in the sealing cover 1, so as to prevent dust from falling out of the sealing cover 1 through the screening holes 213.
The dust remover is fixedly arranged at the discharge end of the belt conveyor, and can be detached independently when dust removal is not needed, so that dust removal can be carried out while discharging.
The working principle of the dust remover for dust fall of the belt conveyor provided by the embodiment of the invention is as follows:
step one: when the vibrating screening mechanism 2 and the wind dust removing mechanism 3 are started, as the feeding baffle 222 is started to default to be in a closed state and the discharging baffle 221 is default to be in an open state, at the moment, the belt conveyor 4 directly conveys crushed stones from the feeding port of the sealing cover 1 to the inside of the sealing cover, the gear piece 232 can be driven to synchronously rotate through the rotation of the driving motor 231, the first rotating piece 233 and the second rotating piece 235 rotate at different speeds, the rotating speed of the second rotating piece 235 is far higher than that of the first rotating piece 233, the discharging baffle 221 is firstly moved upwards to be in an open state through the rotation of the first rotating piece 233, and the connecting rod 223 is rotated through the upward movement of the discharging baffle 221, so that the feeding baffle 222 is driven to synchronously move downwards to be in a closed state, the crushed stones on the belt conveyor 4 are intercepted outside the sealing cover 1, the crushed stones entering the sealing cover 1 each time are kept within a certain range, and the screening bucket 211 is ensured to effectively screen the crushed stones;
step two: the crushed stones entering the sealing cover 1 drop downwards onto the screening hopper 211 by the belt conveyor 4, and the high-speed rotation of the second rotating member 235 can enable the driving rod 234 to drive the screening hopper 211 to vibrate in the vertical direction at high frequency so as to screen the crushed stones, part of dust and particles in the crushed stones are lifted up due to the movement of the crushed stones in the screening process and are distributed in the sealing cover 1, at the moment, the dust is blown into the dust guide pipe fitting 32 by the wind blowing member 33, so that the dust finally flows into the dust accumulation cover 31, and meanwhile, part of dust and particles directly drop into the dust accumulation cover 31 through the screening hopper 211;
step three: since the movement directions of the discharging baffle 221 and the feeding baffle 222 are always opposite, when the first rotating piece 233 drives the discharging baffle 221 to move upwards to an open state again, the feeding baffle 222 is just enabled to move downwards to be closed again, at the moment, crushed stones in the sealing cover 1 are just screened, discharged through the discharging hole, and are reciprocated through the feeding baffle 222 and the discharging baffle 221, and the high-frequency vibration of the screening hopper 211, quantitative screening treatment of the crushed stones is realized, and dust and fine particles in the crushed stones are rapidly screened out;
step four: in the screening process of the crushed stones, part of dust and particles in the crushed stones are lifted up due to the movement of the crushed stones and are distributed in the sealing cover 1, at the moment, the dust is blown into the dust guide pipe fitting 32 by the wind blowing and blowing piece 33, and finally flows into the dust accumulation cover 31 through the dust guide pipe fitting 32, meanwhile, part of dust and particles directly fall into the dust accumulation cover 31 through the screening hopper 211, and water mist is sprayed into the dust accumulation cover 31 through the water spraying pipe fitting 34, so that the dust can be rapidly degraded, and finally the dust and the particles are discharged from the bottom end of the dust accumulation cover 31;
step five: since fine particles in the crushed stones are all screened out, when the crushed stones fall to the external storage area through the screening hopper 211, a large amount of dust is not generated until all the crushed stones are transported to the storage area, and the belt conveyor and the dust remover are closed.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present invention.
