By setting the baffle plate 615, the baffle plate 615 will fit more closely with the conveying plate 5, preventing the waste batteries from escaping from the first conveyor belt 4 and the conveying plate 5 from the bottom of the fixed frame 1.

[0023] One end of the two fixing frames 1 corresponding to the surface and inner wall of the first conveyor belt 4 is fixedly installed with a locking edge so that the locking edge maintains the shape of the first conveyor belt 4, and the back surfaces of the two fixing frames 1 are fixedly installed with a blocking frame 8 so that the blocking frame 8 prevents the waste batteries on the first conveyor belt 4 from falling from both ends. The top of the fixing frame 1 is wrapped by arranging the first protective cover 601 and the second protective cover 602, and cooperates with the blocking frame 8 to prevent the waste batteries from splashing around in case of accidental explosion.

[0024] A fixed support leg 12 is fixedly installed at one end of the bottom position of the fixed frame 1, and an adjustable support leg 11 is fixedly installed at one end of the top position of the fixed frame 1. Support arms 9 are fixedly installed on the surfaces of the adjustable support leg 11 and the fixed support leg 12. The support arms 9 are of a Y-shaped structure, and both ends of the corresponding positions of the two support arms 9 are respectively hinged with articulated arms 10, so that the support arms 9 and the articulated arms 10 form a parallelogram structure; When the above structure is in use, the shape of the fixing frame 1 is changed by adjusting the length of the adjustable supporting leg 11. When the shape of the fixing frame 1 is adjusted, that is, when the inclination angle of the middle part of the fixing frame 1 changes, the inclination angle of the waste batteries between two adjacent conveying plates 5 on the first conveyor belt 4 will change. When the inclination angle becomes lower, more waste batteries are conveyed, which is equivalent to adding the amount of feed to the crushing mechanism. Conversely, when the inclination angle becomes higher, less waste batteries are conveyed, thereby reducing the amount of feed to the crushing mechanism.

[0025] The bottom of the fixed support leg 12 and the adjustable support leg 11 are fixedly provided with a support assembly, the support assembly includes a support frame 14, the bottom of the support frame 14 is provided with a plurality of universal wheels, the fixed support leg 12 is fixedly installed at one end of the support frame 14, the surface of the support frame 14 corresponding to the position of the adjustable support leg 11 is movably sleeved with a first movable sleeve 15, and one end of the opposite surface of the two first movable sleeves 15 is fixedly installed with a first cross bar 16, the adjustable support leg 11 is fixedly installed on the top of the first cross bar 16, and the front and rear ends of the support frame 14 are respectively movably sleeved with second A movable sleeve 17, and one end of the opposite surface of the two second movable sleeves 17 is fixedly installed with a second cross bar 18, the top of the second cross bar 18 is hinged with a support frame 19, and the end of the support frame 19 away from the second cross bar 18 is rotatably connected to a driving cross bar 20, and the front and rear ends of the driving cross bar 20 are respectively fixedly installed with a connecting block 21, the connecting block 21 is fixedly installed at a position between the support arm 9 and the adjustable support leg 11, and one end of the second cross bar 18 is fixedly installed with an electric push rod 22, and the electric push rod 22 is fixedly installed at one end of the inner wall of the support frame 14; When the above structure is in use, the electric push rod 22 drives the second cross bar 18 to move, and then the second cross bar 18 drives the driving cross bar 20 to move through the support frame 19, and the driving cross bar 20 drives the support arm 9 and the adjustable support leg 11 to move through the connecting block 21, thereby changing the horizontal and vertical positions of the support arm 9 and the adjustable support leg 11. Under the action of the parallelogram structure formed by the support arm 9 and the articulated arm 10, the two ends of the fixing frame 1 are always in a parallel state with the ground, and the inclination angle of the middle part of the fixing frame 1 can be adjusted, so that the amount of waste batteries transported can be adjusted. At the same time, when the electric push rod 22 drives the second cross bar 18 and the second movable sleeve 17 to move, the adjustable support leg 11, the first movable sleeve 15 and the first cross bar 16 are also forced to move, thereby providing stable support for the inclination of the fixing frame 1.

[0026] Working principle: When in use, the invention first piles up the waste batteries inside the feeding bin 607. Due to the design of the feeding blade 609, the feeding plate 610, the partition 611, the limit plate 612 and the discharge port 613, the waste batteries inside the main chamber of the feeding bin 607 in a normal state will not fall from the discharge port 613 to the first conveyor belt 4. At this time, the driving motor drives the driving shaft 608 to rotate, so that the waste batteries inside the main chamber of the feeding bin 607 are transported to the middle of the feeding blade 609, and with the rotation of the feeding blade 609 and the feeding plate 610, the waste batteries finally fall from the discharge port 613 to the first conveyor belt 4. At this time, the driving motor drives the driving roller 2 to rotate, and the driving roller 2 cooperates with the driving roller 3 to drive the first conveyor belt 4 to drive, so that the first conveyor belt 4 cooperates with the conveying plate 5 to transport the waste batteries that fall from the discharge port 613 on the first conveyor belt 4 upward, until the waste batteries are transported from the top of the first conveyor belt 4 to the crushing structure; The used batteries are discharged batteries. To prevent the used batteries from accidentally exploding and splashing, the first protective cover 601 and the second protective cover 602 are provided to wrap the top of the fixing frame 1, and the blocking frame 8 is used to prevent the used batteries from falling from the front and rear ends, so that the used batteries can be prevented from splashing in the event of an accidental explosion. The number of used batteries inside the loading bin 607 that fall onto two adjacent conveying plates 5 is higher than the target number. Since the conveying plates 5 fit closely to the inner walls of the first protective cover 601 and the second protective cover 602, the used batteries inside the two adjacent groups of conveying plates 5 do not move relative to each other, that is, the number inside the two adjacent groups of conveying plates 5 does not change until the first conveyor belt 4 cooperates with the conveying plates 5 to convey the used batteries to an inclined position. At this time, due to the inclination, the used batteries will be stacked obliquely toward the conveying plates 5. Since the conveying plates 5 fit closely to the second protective cover 602, the used batteries will also contact the second protective cover 602. Until the conveyor plate 5 drives the waste batteries to move to the position of the discharge frame 604, the excess waste batteries directly enter the discharge frame 604, and at the same time, the servo motor drives one of the transmission shafts 616 to rotate, so that the transmission shaft 616 drives the second conveyor belt 617 to transmit, and the second conveyor belt 617 conveys the excess batteries in the discharge frame 604 to the guide frame 605, and under the tilting effect of the guide frame 605, the batteries pass through the connecting frame 606 and fall into the sub-chamber of the feeding bin 607, and finally return to the first conveyor belt 4 through the discharge port 613, thereby avoiding the situation that the crushing effect is affected by battery accumulation or insufficient supply; By setting a baffle plate 615, wherein the baffle plate 615 is made of elastic material, the baffle plate 615 can be more closely attached to the conveying plate 5, preventing the waste batteries from being separated from the first conveyor belt 4 and the conveying plate 5 from the bottom of the fixing frame 1, and by setting a vent hole 614, the vent hole 614 connects the inside of the sub-chamber of the feeding bin 607 with the outside, so that the sub-chamber is not completely closed, which is convenient for observation and unloading from the sub-chamber; By providing the feeding bin 607 and the feeding blades 609, a long-term loading operation can be achieved in one stacking without manual intervention. At the same time, when it is necessary to adjust the amount of used batteries to be transported, the electric push rod 22 drives the second cross bar 18 to move, and then the second cross bar 18 drives the driving cross bar 20 to move through the support frame 19, and the driving cross bar 20 drives the support arm 9 and the adjustable support leg 11 to move through the connecting block 21, thereby changing the horizontal and vertical positions of the support arm 9 and the adjustable support leg 11. Under the action of the parallelogram structure formed by the support arm 9 and the articulated arm 10, the two ends of the fixed frame 1 are always in a state parallel to the ground, that is, no matter how the electric push rod 22 drives the second cross bar 18 to move, the top and bottom of the fixed frame 1 are always arranged in parallel, and when the horizontal and vertical positions of the support arm 9 and the adjustable support leg 11 move, the shape of the fixed frame 1 is changed, that is, the inclination angle of the middle part of the fixed frame 1 is adjusted, so that the amount of used batteries to be transported can be adjusted. At the same time, the hinge positions of one group of support arms 9 and articulated arms 10 correspond to the center position of the connecting frame 7, so that the shape of the fixed frame 1 can be adjusted conveniently. When the shape of the fixed frame 1 is adjusted, that is, when the inclination angle of the middle part of the fixed frame 1 changes, the inclination angle of the waste batteries between the two adjacent conveying plates 5 on the first conveyor belt 4 will change. When the inclination angle becomes lower, the waste batteries between the two adjacent conveying plates 5 that will not be transported by the second conveyor belt 617 will increase, which is equivalent to adding the amount of feed to the crushing mechanism. On the contrary, when the inclination angle becomes higher, the waste batteries between the two adjacent conveying plates 5 that are not transported by the second conveyor belt 617 will decrease, thereby reducing the amount of feed to the crushing mechanism. Since the servo motor drives the transmission shaft 616 to rotate and the drive motor drives the drive shaft 608 and the drive roller 2 to rotate, vibration will occur, and the vibration will be transmitted to the first conveyor belt 4, and the waste batteries between the two adjacent conveying plates 5 will be evenly tilted, so that the amount can be controlled more precisely.
