As a specific implementation manner of the limestone crushing device provided by the present invention, please refer to fig. 1 to 5, a plurality of baffles 12 are further disposed on the inner side wall of the box body 1, the baffles 12 are disposed in an inclined manner, so as to guide the crushed material to the collecting cart 4. The collecting vehicle 4 is movable, four travelling wheels are arranged at the bottom of the collecting vehicle, when the broken limestone in the collecting vehicle 4 is fully stored, a worker can pull the collecting vehicle 4 to replace the new collecting vehicle 4, the collecting vehicle 4 is very favorable for storing and carrying materials, and the labor intensity of workers is reduced. In addition, a discharge port 13 is formed in the lower portion of the outer wall of the box body 1, the discharge port 13 is hinged to the box body 1, after the collection vehicle 4 is fully stored, the discharge port 13 can be opened, the collection vehicle 4 can be pulled out, and the discharge port facilitates pulling and replacing of the collection vehicle 4.
In one embodiment, the discharge port 13 is a plate-shaped structure, one end of which is hinged to the box 1, and the other end of which is in a cantilever state or a free state, and a sealing gasket is arranged on the other end of which and is used for sealing a gap between the box 1 and the sealing gasket to ensure that dust does not fly.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
