DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Example: Figure 1-Figure 10As shown, a waste battery crushing device described in the present invention includes a shell 1 and a crushing mechanism 6, the crushing mechanism 6 is located inside the shell 1, a drum screen 4 is arranged outside the crushing mechanism 6, a driving mechanism 5 is arranged between the crushing mechanism 6 and the drum screen 4, and an auxiliary mechanism 7 is arranged at the bottom of the drum screen 4; the driving mechanism 5 is configured to drive the crushing mechanism 6 to operate while causing the drum screen 4 to rotate at different speeds; the crushing mechanism 6 includes a first blade 63, when the crushing mechanism 6 is in operation, the first blade 63 cooperates with the second blade 65 fixed to the drum screen 4 to crush the material in the drum screen 4; the drum screen 4 is configured to screen out material particles that meet the standards while cooperating with the crushing mechanism 6; the auxiliary mechanism 7 is configured to assist in accelerating the discharge of the material after the material is crushed.

[0032] In this embodiment, the driving motor 56 is started to drive the driving shaft 51 to rotate, and the coarsely crushed waste batteries are put into the drum screen 4. The rotating drum screen 4 picks out small particles, and the first gear 53 on the driving shaft 51 drives the second gear 55 to rotate, so that the gear ring 52 meshing with the second gear 55 drives the drum screen 4 to rotate. At this time, the drum screen 4 and the driving shaft 51 rotate at different speeds, and the speed of the drum screen 4 is lower than the speed of the driving shaft 51. After the driving motor 56 is started, during the rotation of the connecting plate 61 and the drum screen 4, the first blade 63 cooperates with the second blade 65 to cut, and the waste battery materials in the drum screen 4 are further finely crushed. After crushing, the waste battery materials that meet the required size leak out from the drum screen 4, and the materials entering the inclined drum screen 4 are moved by gravity. The material moves downward toward the lower end of the drum screen 4, and part of the material is intercepted by the second blade 65, and is cut and crushed by the first blade 63 and the second blade 65 during the rotation of the crushing mechanism 6 and the drum screen 4. Part of the material moves toward the lower end of the drum screen 4 from the gap between the second blades 65 when the drum screen 4 rotates, and is intercepted by another group of second blades 65, and so on, so that the material can be fully crushed, and the gap between the second blades 65 near the feed port 13 is larger, so that the material quickly reaches the second group of second blades 65, the material is dispersed and crushed, and the crushing efficiency is improved. At the same time, during the rotation of the drum screen 4, the protrusion 73 is abutted against the guide plate 71, so that the spring 72 at the bottom of the guide plate 71 is compressed, so that the guide plate 71 achieves a vibration effect, thereby accelerating the discharge of the material.

[0033] like Figure 1-Figure 4As shown, the shell 1 includes a base 11 and a cover shell 12, the cover shell 12 is fixedly connected to the top of the base 11, a feed port 13 is provided on the side wall at one end of the cover shell 12, and a discharge port 14 is provided on one side of the cover shell 12, the feed port 13 and the discharge port 14 are not arranged opposite to each other, a group of first support seats 2 and a group of second support seats 3 are fixedly installed at both ends of the top of the base 11, and the heights of the first support seats 2 and the second support seats 3 are different; an arc block 31 is fixedly connected to the top of the second support seat 3, and a ball 32 is arranged on the top of the arc block 31; the drum screen 4 includes annular grooves 41 respectively provided at both ends, the annular grooves 41 cooperate with the ball 32, a fixed plate 42 is fixedly connected to one end of the drum screen 4, the drum screen 4 is inclined, the fixed plate 42 is located at the lower end of the drum screen 4, and the feed port 13 cooperates with the higher end of the drum screen 4.

[0034] In this embodiment, the coarsely crushed waste battery material enters from the upper end of the drum screen 4 through the feed port 13. The upper end of the drum screen 4 is open and the lower end is closed. Two first support seats 2 at different heights are used to support the drive shaft 51, and two second support seats 3 at different heights are used to support the drum screen 4. The balls 32 on the top of the second support seats 3 are stuck in the annular grooves 41 at both ends of the drum screen 4. The drive shaft 51 passes through the drum screen 4 and is concentrically arranged. When the drum screen 4 rotates driven by the driving mechanism 5, the balls 32 roll at the bottom of both ends of the drum screen 4. While supporting the drum screen 4, the friction between the drum screen 4 and the second support seat 3 can be reduced. After the material that meets the required size leaks out of the drum screen 4, it is discharged from the discharge port 14 under the action of the inclined guide plate 71.

[0035] like Figure 2-Figure 10As shown, the driving mechanism 5 also includes a driving shaft 51 that rotates and passes through the drum screen 4, one end of the driving shaft 51 is fixedly connected to a first gear 53, the outer side of the fixed plate 42 is fixedly connected to a gear ring 52, a group of fixed shafts 54 are fixedly connected to the inner wall of the housing 12, and the end of the fixed shaft 54 ​​away from the inner wall of the housing 12 is fixedly connected to a second gear 55, and the second gear 55 is respectively meshed with the first gear 53 and the gear ring 52, and a driving motor 56 is fixedly installed on the top of the first support seat 2; the output end of the driving motor 56 is fixedly connected to the driving shaft 51, and both ends of the driving shaft 51 are rotatably connected to the first support seat 2; the crushing mechanism 6 also includes a group of connecting plates 61 fixedly connected to the driving shaft 51, and the opposite sides of the two connecting plates 61 are fixed A group of connecting rods 62 are fixedly connected, the first blade 63 is fixedly connected to the connecting rod 62, a group of connecting rings 64 are fixedly connected to the drum screen 4, the second blade 65 is fixedly connected to the connecting ring 64, the first blade 63 cooperates with the second blade 65, and a group of baffles 66 are fixedly connected to the outside of the driving shaft 51; the drum screen 4 and the driving shaft 51 are concentrically arranged, and the diameter of the baffle 66 gradually increases from high to low direction of the driving shaft 51; the second blades 65 are arranged in multiple groups, each group of second blades 65 is assembled to be composed of multiple blade assemblies, and there are blade gaps between the multiple blade assemblies; the blade gaps of the multiple groups of second blades 65 gradually decrease from the feeding direction, and the blade gaps of two adjacent groups of second blades 65 are staggered.

[0036] In this embodiment, the driving motor 56 is started to drive the driving shaft 51 to rotate, so that the connecting plate 61 fixedly connected to the driving shaft 51 rotates, and the multiple connecting rods 62 arranged between the two connecting plates 61 also revolve around the driving shaft 51 as the center of the circle. During the rotation process, the first blade 63 spirally distributed on each connecting rod 62 rotates synchronously. When the first blade 63 rotates to the bottom of the drum screen 4, it cooperates with the second blade 65 on the drum screen 4 to cut and crush the material at the bottom of the drum screen 4. While the driving shaft 51 is rotating, the first gear 53 drives the second gear 65 to rotate. The gear 55 rotates on its own, so when the second gear 55 rotates, it drives the gear ring 52 to rotate, thereby causing the drum screen 4 to rotate, and the speed and direction are different from those of the drive shaft 51. The speed of the drum screen 4 is lower than the speed of the drive shaft 51. When the drum screen 4 rotates, it can accelerate the screening of materials, remove waste particles that meet the standards, and larger waste materials continue to remain in the drum screen 4 for crushing. During the crushing process, collision and cutting cause the drum screen 4 to vibrate to prevent the material from clogging the screen holes. At the same time, the multiple baffles 66 on the drive shaft 51 can be used to block and prevent the material from splashing too far during the crushing process.

[0037] In this embodiment, if Figure 8-Figure 10As shown, a plurality of equally spaced connecting rings 64 provided on the drum screen 4 are all provided with second blades 65, and each second blade 65 is composed of a plurality of identical blades, and a gap is left between each blade of the second blade 65. The closer the second blade 65 is to the feed inlet 13, the larger the gap between the blades, and vice versa, the farther away, the smaller the gap, and the gaps between adjacent second blades 65 are staggered, that is, a non-linear setting, the purpose of which is to intercept the material in sections. The larger the gap between the blades of the second blade 65, the smaller the blade of the second blade 65, and vice versa, the smaller the gap between the blades of the second blade 65, the larger the blade of the second blade 65. The baffle 66 is fixedly mounted on the drive shaft 51. From high to low direction of the drive shaft 51, the diameter of the baffle 66 gradually increases, and the number of baffles 66 is relative to the number of connecting rings 64. The vertical distance between the first blade 63 and the second blade 65 is smaller than the sieve hole width of the drum screen 4, and the material cut and crushed by the first blade 63 and the second blade 65 can leak out of the sieve hole. Therefore, at a position close to the feed port 13, the gap between the blades of the second blade 65 is larger, and the gap between the baffle 66 and the second blade 65 is larger. When the drum screen 4 rotates, most of the material can roll through the blade gap of the second blade 65 to the adjacent second blade 65, and so on, so that the material is separated and dispersed in the drum screen 4, so that each set of paired first blades 63 and second blades 65 can be effectively utilized, thereby improving the utilization rate of the first blade 63 and the second blade 65, thereby improving the crushing efficiency, and during the crushing process, the material can still be put into the drum screen 4, and continuous crushing work can be performed.

[0038] like Figure 3 As shown, the auxiliary mechanism 7 includes a guide plate 71 arranged at the bottom of the drum screen 4, the guide plate 71 is inclined, the higher end of the guide plate 71 is rotatably connected to the inner wall of the cover shell 12, a spring 72 is fixedly connected to the bottom of the guide plate 71, the end of the spring 72 away from the guide plate 71 is fixedly connected to the top of the base 11, the lower end of the guide plate 71 cooperates with the discharge port 14, and a protrusion 73 is fixedly connected to the outer side of the connecting ring 64, and the protrusion 73 cooperates with the guide plate 71.

[0039] In this embodiment, when material leaks out from the drum screen 4, it is discharged from the discharge port 14 through the guide plate 71. When the drum screen 4 rotates to a certain angle, the end of the protrusion 73 will abut against the guide plate 71, and the spring 72 at the bottom of the guide plate 71 will be compressed, causing the lower end of the guide plate 71 to move downward. When the protrusion 73 separates from the guide plate 71, the spring 72 pushes the guide plate 71 to return to its original position, thereby causing the guide plate 71 to vibrate, thereby preventing fine materials from adhering to the guide plate 71 and being unable to be discharged from the shell 1.

[0040] Working principle: When in use, start the driving motor 56 to rotate the driving shaft 51, and at the same time, the first gear 53 drives the second gear 55 to rotate, so that the gear ring 52 meshing with the second gear 55 drives the drum screen 4 to rotate. When the drum screen 4 rotates, the balls 32 roll in the annular grooves 41 at both ends of the drum screen 4 to reduce friction, and the coarsely crushed waste battery materials are put into the drum screen 4 from the feed port 13. When the first blade 63 rotates to the bottom of the drum screen 4, it cooperates with the second blade 65 to crush the materials. At the same time, the materials will also move from the blade gap of the second blade 65 to the next second blade 65 under the rotation of the drum screen 4. The second blade 65 is not only used for crushing, but also acts as a partition to prevent the materials from entering the inclined drum screen 4 and then directly rolling down to the lower end of the drum screen 4. The materials are dispersed and crushed through the barriers of the layers of second blades 65. The rotation speed of the first blade 63 is higher than that of the drum screen 4. When the first blade 63 rotates to the bottom of the drum screen 4, The first blade 63 cooperates with the blade of the second blade 65 located at the bottom of the drum screen 4 at this time to crush the material. Material particles smaller than the screen holes of the drum screen 4 leak out from the drum screen 4, and the unbroken materials continue to move to the next second blade 65 during the rotation of the drum screen 4. The blade gap of the second blade 65 farther away from the feed inlet 13 is smaller, so that the overlapping part of the first blade 63 and the second blade 65 increases, so that the material has time to be fully crushed. It is also used to control the flow rate of the material moving to the lower end of the drum screen 4. The larger the gap, the more material passes through, and vice versa. The material leaking out of the drum screen 4 is discharged from the shell 1 under the action of the guide plate 71, and the projection 73 squeezes the guide plate 71 during the rotation of the drum screen 4, so that the spring 72 is compressed and the lower end of the guide plate 71 moves downward. When the projection 73 separates from the guide plate 71, the spring 72 pushes the guide plate 71 to reset, so that the guide plate 71 achieves a vibration effect to avoid the accumulation of fine particles on the guide plate 71.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
