Abstract
The utility model discloses a grain rotary discharging arm structure and a grain returning device in the technical field of conveying equipment. A grain rotary discharging arm structure comprises a mounting seat, a grain conveying pipe, a rotary arm and a discharger, one end of the rotary arm is connected with the mounting seat, the other end of the rotary arm is fixedly connected with the discharger, the grain conveying pipe is connected with a feeding port of the discharger through the rotary arm, and the grain rotary discharging arm structure further comprises a push rod mechanism, a distance measuring sensor, a pull plate and a telescopic discharging pipe. The pull plate is further provided with a distance measuring sensor used for detecting the distance between the pull plate and the grain surface, the push rod mechanism comprises a fixed end and a push rod, the fixed end is fixed to one side of the unloader, the push rod is connected to the lower portion of the fixed end, the side, away from the fixed end, of the push rod is connected with the pull plate, and the distance measuring sensor is electrically connected with the push rod mechanism. And the distance measuring sensor and the push rod mechanism which are arranged in a linkage mode are additionally arranged, so that an outlet of the unloader is at a proper distance from the grain surface, and the problem of dust raising or grain splashing is avoided.
