Sand collecting instrument capable of measuring orientation position of sand inlet in real time

The utility model relates to a sand collector capable of measuring the orientation position of a sand inlet in real time, which comprises a sand and dust collector, a tail wing, a connecting rod, a rotating shaft, a bearing, a support cross arm and a wind direction positioner, wherein one end of the sand and dust collector is provided with a sand inlet, and the other end thereof is connected with the tail wing by the connecting rod; one end of the rotating shaft is connected with the connecting rod, and the other end thereof is connected with the bearing; the support arm and the bearing are connected; and the wind direction positioner and the bearing are connected. The sand collector capable of measuring the orientation position of the sand inlet can know the position of the sand inlet in real time, i.e. whether the sand inlet is accurately aligned to the wind direction or not directly influences the data quality.
