1. An underwater crushing apparatus for an aluminum housing battery, comprising a crusher (1), wherein a feed port is provided at a top end of the crusher (1), and a crushing mechanism is arranged inside the crusher (1) below the feed port; a motor configured to drive the crushing mechanism to rotate is provided at an outer side of the crusher (1); an inner cavity of the crusher (1) is configured to store water, and the crushing mechanism is configured to be immersed in the water; the crusher (1) is provided with a spray mechanism (7) configured to pump the water inside the crusher (1) and spray the water at the feed port; the crusher (1) at a side of the spray mechanism (7) away from the feed port is provided with a channel communicated with the inner cavity of the crusher (1), an opening is provided at a side of the channel away from the spray mechanism (7), and at least two crushed material collection chambers are arranged in the crusher (1) at a side of the opening; and a collection frame (5) is movably arranged in the channel, and the collection frame (5) is configured to raise and lower along the channel and flip at the opening, so as to allow crushed material collected in the collection frame (5) to fall into the crushed material collection chambers;
wherein a material guiding bevel edge is arranged inside the crusher (1) below the feed port;
wherein the crushing mechanism comprises a first crushing part and a second crushing part (4); the first crushing part comprises at least two crushing liner plates (2) and a crushing rotor (3); the crushing rotor (3) is rotatably arranged at a lower end of an inclined section of the material guiding bevel edge, and the crushing liner plates are movably arranged above the crushing rotor (3) and inside the crusher (1) at one end of the crushing rotor (3) away from the material guiding bevel edge, so that when material is sliding along the material guiding bevel edge to the crushing rotor (3), the material is thrown onto the crushing liner plates (2) by means of the rotation of the crushing rotor (3) to be impacted and crushed;
wherein the second crushing part (4) is located in the inner cavity of the crusher (1) that is directly below the material guiding bevel edge; and the second crushing part (4) comprises an upper crushing roller and a lower crushing roller, with rotation directions of the upper crushing roller and the lower crushing roller being opposite;
wherein a depth of the channel is greater than 2 times a height of the collection frame (5), and a height of the channel opening is greater than half the height of the collection frame (5); and a guide rail (6) is arranged inside the channel, the guide rail (6) is configured to restrict the collection frame (5) from raising and lowering; and
wherein at least one baffle plate (52) is arranged inside the collection frame (5), one end of the collection frame (5) at upper and lower ends of the baffle plate (52) is provided with a material leading chute (51) in an inclined manner, and other end of the collection frame (5) at the upper and lower ends of the baffle plate (52) is movably provided with a flip cover (53).
