The telescopic end of the hydraulic cylinder 6 is connected to the mounting plate 8. There are two groups of hydraulic cylinders 6, which are symmetrically arranged on both sides of the kettle body 2. When the hydraulic cylinder 6 is extended, the kettle cover 3 is opened, and the stirring paddle in the kettle body 2 or the inner wall of the kettle body 2 can be cleaned and maintained, or the raw materials to be mixed can be directly put into the kettle body 2.
[0027] like Figure 4 and Figure 5 As shown, the kettle body 2 is further provided with a stirring paddle for mixing and stirring the battery negative electrode material. The stirring paddle is driven by a mixing motor 4, and the mixing motor 4 is mounted on the kettle cover 3. The stirring paddle includes a stirring shaft 14 and a blade 11. One side of the blade 11 is connected to the stirring shaft 14, and the other side is slidably connected to the inner wall of the kettle body 2. A through hole 12 is opened on the blade 11 to accelerate the mixing progress. A material transfer channel 15 is also provided between the blade 11 and the stirring shaft 14.
[0028] The paddles 11 are provided in four groups and are arranged in a circular array around the axis of the stirring shaft 14; the paddles 11 are arranged obliquely in the kettle body 2, and when the stirring shaft 14 drives the paddles 11 to rotate, the paddles 11 scrape off the battery negative electrode material adhering to the kettle body 2 and push it toward the discharge port.
[0029] In order to make the transmission more stable, and under the pushing action of the hydraulic cylinder 6, the kettle body 2 and the kettle cover 3 can be stably reset after separation, the output end of the mixing motor 4 is coaxially arranged with the kettle body 2, and the output end of the mixing motor 4 protrudes from the kettle cover 3 and is connected to a connecting sleeve 13. The stirring shaft 14 and the facing ends of the connecting sleeve 13 are further provided with a spline 16 for transmission, and the connecting sleeve 13 is provided with a keyway adapted to the spline 16.
