Double-dust-suppression metering funnel for bulk grain wharf transfer

The utility model relates to a double dust suppression metering funnel for bulk grain wharf transfer, which comprises a funnel bracket, a receiving funnel, a lower platform, an upper platform, a wind-shield wall, a dust removal device, an air suction device, a weatherproof top cover, a dust shielding device, a chute scale and an unpowered dust suppression device, the dust shielding device is arranged in the middle area of the feeding port at the upper end of an existing material receiving hopper, the dust removing device is arranged on the periphery of the feeding port, the dust shielding device can seal the middle area of the feeding port of the hopper after grains fall down, the dust removing device can enable the periphery of the hopper to be in a negative pressure state, and therefore dust raising during falling of bulk grains is effectively avoided. The split type movable top cover with the anti-falling function is arranged at the upper end of the material receiving hopper, the phenomenon that the top is
