The crushing device for the water conservancy and hydropower engineering according to claim 1, characterized in that: the inner side of the top end of the material pushing plate (603) is fixedly connected with a threaded groove block (609), the inner side of the top end of the material pushing plate (603) is provided with a through groove, and the threaded groove block (609) is arranged at the center of the bottom end of the through groove.
8. A method of using a hydraulic and hydroelectric engineering crushing plant according to claim 1 comprising the steps of:
the method comprises the following steps: firstly, materials to be crushed are put into the inner side of a crushing box (1) from a feed hopper (2), the materials are arranged above a pre-screening mechanism (3), the materials are overturned by the pre-screening mechanism (3), the materials with qualified particle sizes directly fall on the inner side of a stacking box (7), and larger materials can enter the inner side of a deflection crushing mechanism (5);
step two: the materials entering the inner side of the deflection crushing mechanism (5) can be crushed by the deflection crushing mechanism (5) and are conveyed to the inner side of the accumulation box (7), the crushing angle of the materials is changed by adjusting the deflection crushing mechanism (5), larger materials are driven, and the larger materials are prevented from shielding the crushing roller;
step three: when the materials are stacked on the inner side of the stacking box (7), the materials on the inner side of the stacking box (7) can be pushed through the flat-laying material pushing mechanism (6), so that the materials are laid in the stacking box, the materials are prevented from being accumulated at one position in a concentrated mode to cause overflowing of the materials, the materials in the stacking box can be pushed simultaneously, and the materials can be taken out conveniently.
