8. The frame for a dump truck and the method of using the same as set forth in claim 1, comprising the steps of:
the method comprises the following steps: firstly, materials are placed on the inner side of a carriage (4) to realize the transportation of the materials, and in the process of transporting the materials, the carriage (4) is supported by a lifting support mechanism (6), so that the carriage (4) can apply different elastic forces to different positions at the bottom end of the carriage (4) when the materials are transported, the stability of the carriage (4) when the materials are transported is ensured, and the carriage (4) can be lifted;
step two: when the materials need to be unloaded, the materials on the inner side of the carriage (4) are guided by the bidirectional unloading mechanism (8) to be concentrated at the carriage door (5), and the bidirectional unloading mechanism (8) is not clamped with the carriage door (5) through the carriage door lock pin (9) any more at the moment, so that the opening of the carriage door (5) is realized, and the unloading is convenient;
step three: when the tractor is not used, the frame plate (1) can be supported through the supporting leg mechanism (7), so that the contact area with the ground can be increased, the folding of the supporting leg mechanism (7) is facilitated, and the influence of the supporting leg mechanism (7) on the overall movement of the frame is reduced.
