[0037] See also Figure 1-Figure 3 As shown, the crushing mechanism 3 includes a feed frame 301, a motor 302, a first rotating shaft 303, a gear 304 and a blade 305. The feed frame 301 is fixedly connected to the upper rear side of the bracket 2, and the motor 302 is fixedly connected to the lower right side of the feed frame 301. The first rotating shaft 303 is symmetrically rotatably arranged in the lower part of the feed frame 301. The output shaft of the motor 302 is connected to the right end of the first rotating shaft 303 at the rear side through a coupling, and the right part of the first rotating shaft 303 is provided with a gear 304 by a key connection. The two gears 304 are meshed with each other. The blade 305 is fixedly connected to the first rotating shaft 303, and the blade 305 is located in the feed frame 301.

[0038] See also Figure 1 , Figure 4 and Figure 5 As shown, the pushing mechanism 4 includes a conveying frame 401, a second rotating shaft 402, a third rotating shaft 403, a first pulley group 404, an impeller 405 and a second pulley group 406. The conveying frame 401 is arranged in the upper part of the bracket 2 by welding, and the unloading frame 301 is located above the conveying frame 401. The second rotating shaft 402 is rotatably arranged at the rear of the conveying frame 401. The third rotating shaft 403 is rotatably arranged at the rear of the conveying frame 401. The third rotating shaft 403 is located in front of the second rotating shaft 402. The first pulley group 404 is arranged between the right ends of the second rotating shaft 402 and the third rotating shaft 403. A pulley group 404 consists of two pulleys and a flat belt, the right ends of the second rotating shaft 402 and the third rotating shaft 403 are fixedly connected with pulleys, and flat belts are wound around the two pulleys, the second rotating shaft 402 and the third rotating shaft 403 are fixedly connected with impellers 405, and the impellers 405 are located in the conveying frame 401, and a second pulley group 406 is arranged between the first rotating shaft 303 and the second rotating shaft 402 on the rear side, and the second pulley group 406 consists of two pulleys and a flat belt, the left ends of the first rotating shaft 303 and the second rotating shaft 402 on the rear side are fixedly connected with pulleys, and flat belts are wound around the two pulleys.

[0039] When the device is to be used, the staff turns on the motor 302, the output shaft of the motor 302 drives the first rotating shaft 303 on the rear side to rotate, the first rotating shaft 303 on the rear side drives the first rotating shaft 303 on the front side to rotate through the gear 304, the first rotating shaft 303 drives the blade 305 to rotate, and at the same time the first rotating shaft 303 on the rear side drives the second pulley set 406 to operate, the second pulley set 406 drives the second rotating shaft 402 to rotate, the second rotating shaft 402 drives the third rotating shaft 403 to rotate through the first pulley set 404, so that the two impellers 405 rotate, and then the staff pours the batteries into the blanking frame 301, so that the blade 305 can cut the batteries. The battery is crushed so that the electrolyte in the battery flows out, and the electrolyte and the crushed battery fall into the conveying frame 401 and are conveyed downward by the impeller 405. The staff uses tools to collect the crushed battery and the electrolyte, and then classify them. When the device is no longer needed, the staff turns off the motor 302 so that the first rotating shaft 303 no longer drives the blade 305 to rotate, and then stops the impeller 405. In this way, the blade 305 can quickly crush the battery, so that the electrolyte in the battery can flow out fully, and the crushed battery can be conveyed downward by the impeller 405, so as to facilitate the classification and recycling of the battery and the electrolyte.

[0040] Example 2

[0041] Based on Example 1, see Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, it also includes a classification mechanism 5, which includes a shell 501, a classification frame 502, a sleeve 503, a block 504, a pull rod 505 and a first elastic member 506. The shell 501 is fixedly connected to the front side of the conveying frame 401, and the classification frame 502 is slidably arranged at the lower part of the shell 501. The sleeves 503 are fixedly connected to the middle positions of the left and right sides of the lower part of the shell 501. A pull rod 505 is slidably arranged between the two sleeves 503. The lower end of the pull rod 505 is symmetrically provided with a block 504 by welding. The block 504 is used to clamp the classification frame 502. The first elastic member 506 is connected between the top of the block 504 and the top of the sleeve 503. The first elastic member 506 is sleeved on the pull rod 505. The first elastic member 506 is a compression spring, so as to better drive the pull rod 505 and the block 504 to move downward and reset.

[0042] See also Figure 1 , Fig. 9 , Fig.10 and Fig.11As shown, it also includes a collecting mechanism 6, which includes a collecting frame 601, a floating plate 602, a fixing frame 603, an alarm 604 and a valve 605. The collecting frame 601 is fixedly connected to the front side of the top of the base 1, and a floating plate 602 is slidingly arranged on the rear side of the upper part of the collecting frame 601. The fixing frame 603 is fixedly connected to the rear side of the top of the collecting frame 601, and an alarm 604 is installed in the fixing frame 603. The floating plate 602 can trigger the alarm 604 when it moves upwards, and a valve 605 is connected and communicated with the right side of the lower part of the collecting frame 601.

[0043] Initially, valve 605 is connected to the external pipe, and the crushed batteries flow into the classification frame 502 through the conveying frame 401. The classification frame 502 can classify the batteries and electrolytes. The electrolyte falls into the collection frame 601 through the classification frame 502, so that the electrolyte in the collection frame 601 gradually increases. When the electrolyte contacts the floating plate 602, under the action of buoyancy, the electrolyte pushes the floating plate 602 to slide upward to trigger the alarm 604, thereby reminding the staff to discharge the electrolyte in the collection frame 601. The staff opens the valve 605, so that the electrolyte in the collection frame 601 flows out through the external pipe. As the electrolyte in the collection frame 601 decreases, the floating plate 602 moves downward and breaks away from the alarm 604, thereby the alarm is sounded. When the battery in the classification frame 502 needs to be taken out, the staff member pulls the pull rod 505 upwards, and the pull rod 505 drives the card block 504 to move upwards. The first elastic member 506 is compressed accordingly, and the card block 504 is out of contact with the classification frame 502. Then the staff member pulls the classification frame 502 forward to take it out, and then pours out the batteries in the classification frame 502 and puts it back to its original place. Then the staff member releases the pull rod 505, and the first elastic member 506 drives the pull rod 505 and the card block 504 to move downward and reset, so that the card block 504 clamps the classification frame 502 again, thereby preventing the classification frame 502 from moving easily.

[0044] See also Figure 1 and 12 As shown, the extrusion mechanism 7 includes a support frame 701, a screw 702, a handle 703 and an extrusion block 704. The support frame 701 is fixedly connected to the front side of the lower part of the shell 501, and a screw 702 is threadedly arranged at the middle position of the upper part of the support frame 701. The handle 703 is arranged on the top of the screw 702 by welding, and the extrusion block 704 is rotatably connected to the lower part of the screw 702.

[0045] When the classification frame 502 moves to the bottom of the squeezing block 704, the staff turns the handle 703 to drive the screw 702 to rotate, so that the screw 702 drives the squeezing block 704 to move downward, and the squeezing block 704 squeezes the batteries in the classification frame 502, thereby squeezing out the water in the batteries. When the squeezing is completed, the staff reverses the handle 703 to drive the screw 702 to reverse, and the screw 702 drives the squeezing block 704 to move upward and reset. In this way, the electrolyte in the battery can be squeezed out by squeezing the squeezing block 704, so that the batteries and the electrolyte can be better classified.

[0046] See also Figure 1 , Fig.13 , Fig.14 and Fig.15 As shown, it also includes a blocking mechanism 8, which includes a pushing frame 801, a support plate 802, a guide rod 803, a second elastic member 804 and a baffle 805. The front side of the bottom of the conveying frame 401 is fixedly connected to a guide seat of the support plate 802, and the left and right parts of the support plate 802 are slidably provided with guide rods 803. The pushing frame 801 is fixedly connected between the front ends of the two guide rods 803. The front side of the pushing frame 801 contacts the rear side of the classification frame 502, and the left and right sides of the upper part of the pushing frame 801 are both inclined surfaces. Two second elastic members 804 are connected between the rear side of the pushing frame 801 and the front side of the support plate 802. The second elastic member 804 is sleeved on the guide rod 803, and a baffle 805 is rotatably provided on the front side of the conveying upper part. The pushing frame 801 can clamp the baffle 805, and the inclined surfaces on the left and right sides of the upper part of the pushing frame 801 will squeeze the baffle 805 to rotate.

[0047] Initially, the second elastic member 804 is in a compressed state. When the classification frame 502 moves forward, the second elastic member 804 gradually resets, thereby driving the guide rod 803 to move forward, and the guide rod 803 drives the pushing frame 801 to move forward. The pushing frame 801 moves forward and disengages from the baffle 805. The baffle 805 rotates downward under the action of gravity, so that the baffle 805 blocks the conveying frame 401, and the batteries in the conveying frame 401 no longer flow out, thereby facilitating the staff to pour out the batteries in the classification frame 502. When the staff puts the classification frame 502 back to its original place, the classification frame 502 is squeezed to push the frame 801 to move backward, and the inclined surfaces on the left and right sides of the upper part of the pushing frame 801 contact the baffle 805, thereby squeezing the baffle 805 to rotate upward and reset, so that the batteries in the conveying frame 401 can flow into the classification frame 502 again.

Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
