Ultrasonic ranging obstacle avoidance device of bin filling distributor

Abstract

The utility model discloses a kind of ultrasonic ranging obstacle avoidance devices of warehouse filling distributor in the field of grain conveying equipment, including left and right detection module and upper and lower detection module being rotatably arranged in the front end of telescopic frame of warehouse filling distributor along horizontal direction and vertical direction, both are electrically connected with controller, the controller is also electrically connected with azimuth adjusting module and pitch adjusting module on warehouse filling distributor. The controller is configured as, can according to the rotating direction and angle of azimuth adjusting module and pitch adjusting module control left and right detection module and upper and lower detection module rotate the same angle in opposite direction, to ensure that no matter telescopic frame turns to what position, the detection direction of left and right detection module is always perpendicular to the wall surface of both sides of granary, the detection direction of upper and lower detection module is always perpendicular to the top surface of granary, to avoid the detection error caused by angle change, improve distance detection precision, ensure the safety of warehouse filling distributor operation.
