The preparation equipment of the graphite cathode material of the battery as claimed in claim 1, wherein the stirring mechanism comprises a guide plate and a driving motor c arranged at the end part of the guide plate, wherein a guide rod driven by the driving motor c is movably arranged in the guide plate, and the guide plate is connected with a guide seat through a guide rod thread;
be provided with pneumatic cylinder b on the guide holder, the end plate rather than perpendicular setting is installed to pneumatic cylinder b's flexible end to install agitator motor in the other end below of end plate, agitator motor's output shaft has the puddler that extends to in the agitator tank, stirring vane is installed to the tip of puddler.
3. A method of using the battery graphite anode material preparation apparatus of any one of claims 1-2, comprising the steps of:
step one: the telescopic end of the hydraulic cylinder a is driven to extend outwards, and the sliding block at the end part of the inclined stay bar is pushed to slide outwards towards the base plate under the dead weight extrusion of the swinging assembly, so that the swinging assembly is sunk;
step two: placing a stirring tank storing graphite powder to be crushed and stirred above a fixed adjusting mechanism through a forklift, rotating an adjusting rod adjusting supporting plate below a towing ring, driving a telescopic end of a hydraulic cylinder a to shrink inwards, and jacking up a swinging assembly on an inclined supporting rod through a sliding block sliding towards the center of a base plate, so that the stirring tank is erected;
step three: the stirring mechanism is driven to extend the stirring rod into the stirring tank, the stirring motor is started to drive the stirring blades to crush at a high speed, the driving motor b is started to drive the three groups of driving gears to synchronously rotate by matching with the transmission toothed ring, the driving motor b downwardly extrudes the guide frame with the toothed plate to pull the connecting ring to rapidly rise, the reset spring is compressed, the toothed plate of the guide frame can be separated when the driving gears rotate to the notch, the connecting ring rapidly sinks under the action of the reset spring, the inner side of the bottom of the inner ring is impacted by the guide frame to vibrate, and graphite powder at the bottom of the stirring tank can be vibrated to participate in crushing and stirring;
step four: after the graphite powder is crushed and stirred, adding a polymer and an additive for continuous stirring, starting a driving motor a to drive a guide wheel to move in a corrugated groove of an outer ring, further driving a stirring tank to swing and eccentrically rotate, so that raw materials in the stirring tank can fully flow and participate in mixing and stirring;
step five: after the crushing and mixing stirring are finished, the stirring mechanism is withdrawn, the fixed adjusting mechanism is driven to sink again, the stirring tank is enabled to act on the substrate, and then the stirring tank is conveniently brought into the next working procedure through a forklift.
