Powder sampling device for concrete production

The utility model relates to the technical field of concrete production, in particular to a powder sampling device for concrete production, which is moved by screwing and movably matching with sliding constraint and can move for blanking and sampling, so that the practicability is improved. Comprising a first support, a concrete charging basket and a discharging port, the output end of the bottom of the concrete charging basket is communicated with the top end of the discharging port, the sampling device further comprises a sampling mechanism, the sampling mechanism is used for sampling powder discharging, and the sampling mechanism comprises a support, a motor, a speed reducer, a threaded rod, a sliding rail, a sliding sleeve, a connecting frame, a threaded pipe, a mounting sleeve, a mounting block and a sampling container; the outer side of a threaded pipe is connected with the inner side of a connecting frame, the top end of the connecting frame is connected with the bottom end of a sliding sleeve, the sli
