The crawler conveyor 2 is provided with a clamping component, and the clamping component is used to drive the waste batteries 5 to move. The clamping component is provided with a top striking component, and the top striking component is used to control the clamping component to clamp waste batteries 5 of different sizes.

[0034] The blade of the cutting knife 7 is made of titanium to avoid being corroded by the electrolyte.

[0035] The clamping components include a push block 81, a mounting block 82, a screw 83, a clamping plate 84, a reset spring 85, a column gear 86, a mounting box 87, a sliding tooth plate 88 and a pressure spring 89. Two push blocks 81 and two mounting blocks 82 are fixedly connected to the two crawler conveyors 2. Each mounting block 82 is threadedly connected to a screw 83. Each screw 83 is rotatably connected to a clamping plate 84. The clamping plate 84 is used to clamp the waste batteries 5. Each clamping plate 84 is slidably connected to four mounting blocks 82 respectively. A reset spring (85) is connected between the clamping plate 84 and the inside of the screw 83. A column gear 86 is fixedly connected to the screw 83. The two crawler conveyors 2 are bolted to a mounting box 87. Each mounting box 87 is slidably connected to a sliding tooth plate 88. Several pressure springs 89 are connected between the sliding tooth plate 88 and the mounting box 87.

[0036] The striking component includes a mounting frame 91, a rotating rod 92, a cam 93, a torsion spring 94 and a fixed tooth plate 95. The four screw rods 83 are rotatably connected to the mounting frame 91, and the four mounting frames 91 are respectively slidably connected to the four mounting blocks 82. Each mounting frame 91 is threadedly connected to a rotating rod 92, and each rotating rod 92 is fixedly connected to a cam 93. The cam 93 is used to drive the sliding tooth plate 88 to descend. A torsion spring 94 is connected between the rotating rod 92 and the mounting frame 91. Two fixed tooth plates 95 are connected to the base 1 by bolts, and the two fixed tooth plates 95 are symmetrically arranged.

[0037] The initial position of the column gear 86 and the fixed tooth plate 95 are not in the same plane.

[0038] At first, the user places the waste battery 5 on the placement slot on the placement rack, and then the user controls the crawler conveyor 2 to start running. The operation of the two crawler conveyors 2 will drive the push block 81 and the mounting block 82 to rotate with the crawler wheels. The push block 81 will contact the waste battery 5 during the movement, and the push block 81 will push the waste battery 5 toward the storage frame 6. The movement of the mounting block 82 will drive the screw rod 83 and the column gear 86 to move together. The column gear 86 will mesh with the sliding gear plate 88 during the movement, so that the column gear 86 will rotate. The rotation of the column gear 86 will drive the screw rod 83 to rotate. The screw 83 will move toward the direction close to the waste battery 5 during the rotation process. The clamping plate 84 hit by the movement of the screw 83 moves together, and the clamping plate 84 and the waste battery The screw 83 continues to move after the battery 5 contacts, and the clamping plate 84 extends into the screw 83, and the reset spring 85 is compressed. During the process of the clamping plate 84 extending into the screw 83, the clamping plate 84 squeezes the rotating rod 92, and the rotating rod 92 is squeezed by the clamping plate 84 and extends out of the screw 83. During the process of the rotating rod 92 extending out of the screw 83, it meshes with the mounting frame 91, so that the rotating rod 92 rotates, and the rotation of the rotating rod 92 drives the cam 93 to rotate, and the torsion spring 94 is twisted. During the rotation of the cam 93, the sliding tooth plate 88 is squeezed, and the sliding tooth plate 88 is extended into the mounting box 87, and the pressure spring 89 is compressed, so that the column gear 86 and the sliding tooth plate 88 are disengaged, and the waste battery 5 is clamped by two of the clamping plates 84, and the crawler conveyor The crawler belt continues to run, and the two clamping plates 84 drive the waste battery 5 to move together. During the movement of the waste battery 5, the cover on the electrolyte injection port of the waste battery 5 will be cut off by the cutting knife 7, and the cut cover will fall on the filter screen on the electrolyte collection box 3, and the cover will fall into the storage frame 6 along the filter screen. The installation block 82 moves to drive the rotating rod 92 and the convex plate 93 to move. After the convex plate 93 and the sliding tooth plate 88 fall off, the pressure spring 89 is reset to drive the sliding tooth plate 88 to reset. After the cover of the waste battery 5 is cut off, the electrolyte in the waste battery 5 will flow out through the injection port of the waste battery 5, and the waste battery 5 will fall into the electrolyte collection box 3. The column gear 86 continues to move and meshes with the fixed tooth plate 95, so that the column gear 86 is reversed and returned. The column gear 86 reverses and drives the screw rod 83 to reset. The reset spring 85 resets and drives the clamping plate 84 to extend out of the screw rod 83. The torsion spring 94 resets and drives the rotating rod 92 to reset. The rotating rod 92 resets and drives the convex plate 93 to reset. After the clamping plate 84 and the screw 83 are reset, the column gear 86 will be separated from the fixed tooth plate 95. After the clamping plate 84 and the waste battery 5 are separated, the user takes away the waste battery 5, and then uses it to place the unprocessed waste battery 5 on the placement table 4 again. The drainage treatment of the waste battery 5 is completed in this reciprocating manner. In this way, waste batteries 5 of different specifications can be stably clamped, the applicability of the device is improved, and by cutting off the cover, the waste liquid in the waste battery 5 can be quickly discharged from the waste battery 5, thereby improving the work efficiency.
