Material distributing hopper

The invention discloses a material distributing hopper. The material distributing hopper comprises a main hopper body. The bottom of the main hopper body is divided into two and extends downwards to form two distributing hopper bodies. The bottom of the main hopper body is provided with a lower flap plate in the hinged mode, and a hinge shaft is parallel to an intersecting line of the two distributing hopper bodies. An upper flap plate is arranged above the lower flap plate, the upper flap plate is a V-shaped plate opening downward, and the free end of the lower flap plate is placed in a V-shaped cavity of the upper flap plate. The V-shaped top edge of the upper flap plate is provided with a connecting rod, and the length direction of the connecting rod is parallel to the axial direction of the hinge shaft. Two ends of the connecting rod are provided with a screw nut mechanism, and the screw nut mechanism drives the upper flap plate to be displaced in the direction perpendicular to thelength direction of the
