Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-4, an ore crushing device for mine production, including box 1, the welding of box 1 upper end has feed inlet 2, a pair of first driving shaft 3 is installed to 1 inside top of box, the driving shaft links to each other with external power equipment motor, the equal fixed mounting in 3 outsides of first driving shaft has coarse crushing roller 4, the equal welding of box 1 both sides inner wall surface has coarse crushing wall 5, coarse crushing wall 5 is located coarse crushing roller 4 one side, 1 inside fixed mounting of box has mount 6, mount 6 is located first driving shaft 3 below, mount 6 one side fixed mounting has first door spare 7.

First driving shaft 3 drives coarse crushing roller 4 and rotates, between coarse crushing roller 4 and the coarse crushing roller 4, all can carry out crushing work between coarse crushing roller 4 and the coarse crushing wall 5, and the design of coarse crushing wall 5 can prevent that the gap between coarse crushing roller 4 and the 1 inner wall of box from dropping the stone, leads to broken inhomogeneous.

First door spare 7 includes connecting plate 71, dead slot 72 and adjustable fender 73, and connecting plate 71 welds between mount 6 and box 1 and the slope sets up, and the inside dead slot 72 of having seted up of connecting plate 71, and the movable fender 73 of activity cartridge has in the dead slot 72, and mount 6 opposite side fixed mounting has second door spare 8, and second door spare 8 is the same with first door spare 7 structure, and the welding of mount 6 below one side has ejection of compact board 9.

When the movable baffle 73 is pulled out, the empty groove 72 is exposed, the stones passing through the first crushing process above the empty groove 72 can fall off from the empty groove 72, the discharge plate 9 arranged in the device is positioned below the first door part 7 or the second door part 8, the example that the discharge plate 9 is arranged below the second door part 8 is taken as the lower part for description, and when the requirement on the crushing degree of the ores is not high, the movable baffle 73 in the second door part 8 is opened, so that the ores fall off from the discharge plate 9; when the requirement for the degree of crushing of ore is high, the flapper 73 inside the first door 7 is opened so that ore falls below the inside of the box 1.
