[0025] Embodiment One: Please refer to Figures 1 to 5 The utility model provides a kind of technical scheme: a kind of ore exploitation crushing device, the ore exploitation crushing device includes: crushing roller 1, crushing roller 1 is provided with two groups, crushing roller 1 one end is provided with transmission gear 3, one transmission gear 3 one end surface is fixedly connected with driven wheel 4, driven wheel 4 is connected with driving wheel 5 by transmission belt 11, driving wheel 5 one end is connected with rotary motor 2;

[0026] Support frame 6, support frame 6 is provided with discharge pipe 7 in, support frame 6 top is provided with feeding pipe 8;

[0027] When using, ore is poured into device by feeding pipe 8, then driven wheel 4 is rotated counterclockwise by starting rotary motor 2, so that transmission gear 3 connected with driven wheel 4 is rotated counterclockwise, so that two groups of crushing roller 1 are rotated in opposite directions, so that ore is better into the gap of two groups of crushing roller 1, so that ore is uniformly crushed under the rotation of crushing roller 1, then the ore that is crushed is excluded by discharge pipe 7, so that the problem that the size of ore after crushing is not uniform to affect subsequent processing is avoided.

[0028] The embodiment two is based on the embodiment one, and the crushing rollers 1 are arranged for crushing the materials more uniformly. The crushing rollers 1 are located in the support frame 6. The surfaces of the two groups of crushing rollers 1 are fixedly connected with a plurality of linear equidistant crushing teeth 9. The crushing teeth 9 on the crushing rollers 1 in any one group are clamped between the crushing teeth 9 on the surfaces of the crushing rollers 1 in the other group. The auxiliary teeth 10 are arranged between the crushing teeth 9. The auxiliary teeth 10 are evenly distributed in multiple groups on the surfaces of the crushing rollers 1. The auxiliary teeth 10 are attached to the side surfaces of the crushing teeth 9 on the two sides. One end of the auxiliary teeth 10 is fixedly installed on the side surface of the inner wall of the support frame 6.
