In order to illustrate the technical solution described in the utility model, the following specific examples will be used for illustration.

Fig. 1 shows the structure of the positive electrode material pulverization device provided by the embodiment of the present invention, and only the parts related to the embodiment of the present invention are shown for convenience of description.

As shown in Figure 1, the positive electrode material crushing device provided in this embodiment includes a main body frame 1, a base pedestal 2 is placed inside the main body frame 1, a support beam 3 is fixed on the upper part of the main body frame 1, and the support beam 3 A movable hanger 4 is installed on the top of the hanger 4, and a number of pivoting arms 5 are arranged on both sides of the hanger 4. The rotating shafts at the ends of all the pivoting arms 5 are connected to a pressing plate 6, and the pressing plate 6 is located above the base pedestal 2. The hanging A hydraulic cylinder 7 is also arranged downward on the frame 4, and the hydraulic cylinder 7 is located above the press plate 6. A scraper mechanism 8 is also provided at the entrance of the base pedestal 2, and a slope is provided at the exit position of the base pedestal 2. Plate 9, collecting bin 10 below the sloping plate 9.

The working process of this device is as follows:

First place the sintered positive electrode material on the base pedestal, then control the rotation of the rotating arm, and then press down the pressure plate, which will flatten and compact the positive electrode material, then control the hydraulic cylinder to press down the pressure plate, and then drive the hanger on the support beam The upper reciprocating movement realizes the crushing of the positive electrode material. After the completion, the pressing plate is retracted, and the crushed positive electrode material is scraped into the collection bin through the scraping mechanism, and then enters the next screening process.
