[0029] As Figure 1 and Figure 2As shown, a kind of lithium battery graphite negative electrode material crushing processing device, including outer shell 1, the inside of outer shell 1 is equipped with crushing cone 2, crushing cone 2 top is equipped with and itself corresponds and is fixedly connected with outer shell 1 cover 11, cover 11 inside is equipped with and crushing cone 2 corresponding conical recess 12, the distance between conical recess 12 and crushing cone 2 does not exceed 1cm, conical recess 12 top is equipped with and itself communication inverted conical feed inlet 13, the other end of crushing cone 2 is movably connected with adjusting rod 22 by non-circular center position connecting rod 21, adjusting rod 22 is conical as a whole, adjusting rod 22 outside is equipped with and crushing cone 2 is fixedly connected with conical limiting sleeve 24 of the end away from cover 11, adjusting rod 22 outside is equipped with and outer shell 1 corresponding mill wheel 23, the distance between limiting sleeve 24 and adjusting rod 22 is same with the distance between conical recess 12 and crushing cone 2.

[0030] In the embodiment, the utility model discloses a crushing cone 2 in the outer shell 1 is configured, and the corresponding cover 11 is cooperated to realize the fine crushing effect.The conical design of crushing cone 2 ensures that the material is smoothly entered into mill wheel 23 for further fine grinding under the action of gravity.The centrifugal force generated by the rotation of mill wheel 23 makes raw material particles impact the side wall and be crushed into required particles.At the same time, the rotation of mill wheel 23 drives the rotation of non-circular center position connecting rod 21, and crushing cone 2 rotates along connecting rod 21, i.e.crushing cone 2 carries out two kinds of rotational motion- revolution and rotation simultaneously, thereby improving the crushing efficiency.

[0031] As Figure 3 And Figure 4Further optimization design of the lithium battery graphite negative electrode material breaking processing device shown includes that an adjusting ball 25 fixedly connected with the adjusting rod 22 is arranged in the inner side of the connecting rod 21 close to one end of the adjusting rod 22, which allows fine adjustment of the position of the breaking cone 2 in rotation to better adapt to the conical groove. The transmission gear 14 is fixedly connected to the end of the adjusting rod 22 away from the adjusting ball 25, and the gear ring 15 is arranged outside the transmission gear 14 and engaged with the transmission gear 14, which makes the rotating movement of the adjusting rod 22 more stable.
