Novel integral type back turnover device for dumper

The invention discloses a novel integral type back turnover device for a dumper. The novel integral type back turnover device for the dumper comprises a frame; a back turnover device is welded onto the frame; the back turnover device comprises a first turnover upper support welding piece, a second turnover upper support welding piece and a turnover shaft which are fixedly connected onto a bottom plate of the dumper; a turnover lower support welding piece is arranged on the rear portion of the frame; the turnover shaft is arranged inside the turnover lower support welding piece; two ends of the turnover shaft extend out of the turnover lower support welding piece to be matched with the first turnover upper support welding piece and the second turnover upper support welding piece; the first turnover upper support welding piece and the second turnover upper support welding piece are symmetrically arranged. The novel integral type back turnover device for the dumper has the advantages of being free of auxiliary frame, reasonable in structure and firm and reliable in connection, reducing self-weight of the dumper, reducing costs for material utilization and production assembling due to the fact that the carriage bottom plate and the frame are connected through the back turnover device, being simple in structure and convenient to produce and reducing production costs.
