Material conveying device

The utility model provides a material conveying device which comprises an installation frame, and two sets of first connecting mechanisms and second connecting mechanisms are arranged on the installation frame, connected with a telescopic rotating rod and a rotating rod through fisheye connectors respectively and rotationally connected with the side walls of the two sides of a material conveying groove. When the inclination angle of the material conveying groove does not need to be adjusted, due to the fact that the telescopic rotating rod and the rotating rod are different in length and rotating radius, self-locking can be achieved when the telescopic rotating rod is connected with the material conveying groove, and it is guaranteed that the material conveying groove is stably installed. When the material conveying groove needs to be adjusted, the needed angle is determined according to the material property and the conventional experience in the field, the telescopic rotating rod and the rotating rod are ro
