[0026] First, place the device on a suitable workbench, then turn on the power motor 5. The power motor 5 drives the main shaft to rotate. Through the transmission of the belt and pulley, the linkage shaft 8 rotates. The linkage shaft 8 drives the cutter disc 10 and the cutter bar 11 to rotate simultaneously. Put the waste lithium battery into the upper feeding cylinder 1, and the cutter disc 10 and the cutter bar 11 efficiently crush the waste lithium battery in the casing 2. The locking device facilitates the disassembly and installation of the screening disc 3 at the position of the receiving disc 14; since the diameter of the second leakage holes 19 is smaller than that of the first leakage holes 20, the crushed waste lithium battery enters the first leakage holes 20 through the second leakage holes 19, so as to facilitate the collection of the crushed waste lithium battery through the first leakage holes 20. By replacing the screening disc 3 with different diameters of the second leakage holes 19, it is convenient to collect the waste lithium battery with different particle sizes after crushing; a gap is provided between the screening disc 3 and the receiving disc 3, which facilitates the crushed waste lithium battery to fall below the casing 2 through the cooperation of the second leakage holes 19 and the first leakage holes 20, thus facilitating the collection of the waste lithium battery.

[0027] A square shaft 22 is fixedly connected to the middle part of the linkage shaft 8, and the cutter disc 10 is fixedly connected to the square shaft 22.

[0028] Through the fixed connection between the cutter disc 10 and the square shaft 22, it is convenient to drive the cutter disc 10 and the cutter bar 11 to rotate by the rotation of the linkage shaft 8, which is convenient for efficiently crushing the waste lithium battery.

[0029] The locking device includes a locking plate 15 inserted into the front and rear sides of the sieve plate 3. The locking plate 15 is fixedly provided with a fixing column 16, which is inserted into the machine frame 4.

When the locking plates 15 are disengaged from the square tube 7, the position of the sieve plate 3 in the receiving tray 14 can be freely moved at this time, thus facilitating the disassembly of the sieve plate 3.

[0031] The cutter disc 10 is provided with a plurality of U-shaped grooves 9, and an arc-shaped cutting edge portion is formed between adjacent U-shaped grooves 9.

[0032] The cutting edge portion is convenient for cutting waste lithium batteries, thus playing a role in crushing waste lithium batteries.

[0036] The rib plates 21 have a supporting function. Through the fixed connection between the rib plates 21 and the receiving tray 14, the stability of the receiving tray 14 inside the machine shell 2 is improved.

[0037] On the upper part of the right end face of the sieve plate 3, two pulling grooves 12 symmetrically arranged along the axis of the sieve plate 3 are provided.

[0038] Through the pulling grooves 12, it is convenient to adjust the position of the sieve plate 3 in the receiving tray 14, and it is convenient for the staff to disassemble and clean the sieve plate 3.

[0039] The feeding cylinder 1 is in an inverted cone shape.

[0040] Through the inverted cone-shaped feeding cylinder 1, it is convenient to convey waste lithium batteries into the inside of the machine shell 2, preparing for subsequent crushing.

[0041] When the utility model is in use, first place the device on a suitable workbench, then turn on the power motor 5. The power motor 5 drives the main shaft to rotate. Through the transmission of the belt pulley and the belt, the linkage shaft 8 rotates. The linkage shaft 8 drives the cutter head 10 and the cutter bar 11 to rotate simultaneously. Put the waste lithium battery into the feeding cylinder 1, and the cutter head 10 and the cutter bar 11 efficiently crush the waste lithium battery in the machine shell 2. The locking device facilitates the disassembly and installation of the sieve plate 3 at the position of the receiving plate 14.
