Technical Field
[0001] This utility model belongs to the field of carbon brush processing technology, specifically relating to a waste carbon brush crushing device. Background Technology
[0002] Carbon brushes, as a sliding contact component, are widely used in motors. The main material of carbon brushes is carbon, so they are very easy to wear during use. When carbon brushes are severely worn, they need to be replaced. The replaced carbon brushes are scrapped, but throwing them away directly would waste materials and cause environmental pollution. Therefore, it is necessary to recycle scrapped carbon brushes.
[0003] Currently, commonly used recycling equipment typically stores discarded carbon brushes in a unified manner. Once a certain number of discarded carbon brushes have accumulated, they are transferred to processing equipment for crushing. However, during the crushing process, larger blocks are usually mixed with fine particles. These fine particles fall from the gaps in the blocks to the bottom layer. As crushing progresses, the number of fine particles increases. When the upper blocks are impacted, the fine particles in the lower layer reduce the impact on the blocks, resulting in a decrease in overall crushing efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a waste carbon brush crushing device that can separate fine particles in a timely manner.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a waste carbon brush crushing device, comprising a container with an inner liner, the inner liner having an upper opening through which the waste carbon brush can be inserted. The key structural feature is that a flat support is connected to the lower end of the container, a portal frame is mounted on the flat support, and a driving device is mounted on the portal frame. The inner liner is connected to the container via a flat support shaft, and a driven gear is mounted on the free end of the flat support shaft. The driving device is connected to the driven gear and can drive the driven gear. The gears rotate, causing the inner liner to flip from a vertical position to an inclined position. An impact hammer is also connected to the gantry frame. The impact hammer can enter the inner liner in the vertical position and repeatedly beat the waste carbon brushes. The inner liner includes a straight cylinder with an expansion cover connected to it. The expansion cover has holes distributed on it. A hemispherical cover is connected to the lower end of the straight cylinder. During the process of the inner liner flipping from a vertical position to an inclined position, the waste carbon brushes move from the hemispherical cover into the expansion cover, and fine particles that meet the requirements will flow out from the holes.
[0006] Furthermore, the portal frame includes two symmetrically arranged vertical support arms, with a horizontal suspension beam connected between the upper ends of the two vertical support arms and the lower ends fixed to the flat extension seat. The impact hammer is connected to the horizontal suspension beam via an electric telescopic rod.
[0007] Furthermore, the horizontal lifting beam is located above the container box, and the drive unit is mounted on the horizontal lifting beam. The drive unit includes a drive motor, which is connected to the horizontal lifting beam.
[0008] Furthermore, a drive gear is mounted on the output shaft of the drive motor. The drive gear is located directly above the driven gear, and the drive gear and the driven gear are connected by a transmission chain.
[0009] Furthermore, a strip-shaped opening is provided on the straight cylinder body, which is set along the length direction of the straight cylinder body. The two ends of the strip-shaped opening are closed, and the expansion cover is assembled at the strip-shaped opening.
[0010] Furthermore, the expansion cover includes a main body and end caps. The end caps are fixed at both ends of the main body. The main body has a U-shaped cross-section, and the area of the end caps is half that of the hemispherical cover. An array of holes is distributed on the main body.
[0011] Furthermore, limit rods are symmetrically installed at the bottom of the inner liner, and arc-shaped rail grooves are respectively provided on the two side walls of the accommodating box. The ends of the limit rods fit into the arc-shaped rail grooves and can slide within the arc-shaped rail grooves.
[0012] Furthermore, the container has a rectangular slot, into which a storage drawer is inserted. The storage drawer is located below the inner liner and is slidably connected to the inner wall of the container. The storage drawer has a pull ring.
[0013] Furthermore, the upper end of the storage drawer is provided with a bottom support plate, the two ends of which are connected to the inner wall of the container. The bottom support plate is provided with a feeding channel, which is set along the length of the bottom support plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting an expansion cover on the inner liner and distributing holes in an array on the expansion cover, and cooperating with the drive component, the drive component is connected to the driven gear, so that the drive component can drive the inner liner to rotate, thereby moving the waste carbon brush in the inner liner from the hemispherical cover to the main body, and then allowing the fine particles to flow out from the holes, realizing the separation of fine particles from larger blocks and improving the overall crushing efficiency;
[0015] This invention can flip the inner liner from a vertical position to an inclined position, and when the inner liner is in the vertical position, it can hammer the scrapped carbon brushes. When the inner liner is in the inclined position, it can separate the fine particles, ensuring that the impact force on the scrapped carbon brushes is not dispersed, thus improving the overall crushing efficiency.

[0025] See Figures 1 to 6 As shown, a waste carbon brush crushing device includes a container 1 with an upper opening. An inner liner 2 is installed inside the container 1, and the upper end of the inner liner 2 also has an upper opening. Waste carbon brushes can be placed into the inner liner 2 through the upper opening. A flat extension seat 3 is connected to the lower end of the container 1. The two ends of the flat extension seat 3 are located on both sides of the container 1. A gantry frame is provided on the flat extension seat 3, and an impact component 4 is installed on the gantry frame. The impact component 4 can crush the waste carbon brushes in the inner liner 2. At the same time, a driving device 5 is also connected to the gantry frame. The driving device 5 can drive the inner liner 2 to rotate inside the container 1, so that the fine particles formed by the impact component 4 can be discharged from the inner liner 2 in time, until all the waste carbon brushes are crushed into fine particles.
[0026] The aforementioned portal frame includes two vertical support arms 6, which are symmetrically arranged on both sides of the housing 1. A horizontal suspension beam 7 is connected between the upper ends of the two vertical support arms 6, and the lower ends are fixed to the flat extension seat 3. The horizontal suspension beam 7 is located above the housing 1. An impact component 4 is connected to the horizontal suspension beam 7 and is located directly above the inner liner 2. The impact component 4 includes an electric telescopic rod 8 and an impact hammer 9. The impact hammer 9 is connected to the power end of the electric telescopic rod 8. The electric telescopic rod 8 can control the impact hammer 9 to move downward into the inner liner 2 and periodically hammer the waste carbon brushes in the inner liner 2, thereby crushing the waste carbon brushes in the inner liner 2.
[0027] Two horizontal support shafts 10 are symmetrically connected to the outer side of the inner liner 2, and circular grooves are respectively opened on the two side walls of the housing 1. The free ends of the horizontal support shafts 10 pass through the corresponding circular grooves and extend out of the housing 1. The horizontal support shafts 10 can rotate within the circular grooves without separating from them. At this time, a drive device 5 is installed on the horizontal lifting beam 7, and a driven gear 11 is installed on the free end of any one of the horizontal support shafts 10. The drive device 5 can be connected to the driven gear 11 and can drive the horizontal support shaft 10 to rotate within the circular groove, thereby causing the inner liner 2 to flip within the housing 1. Specifically:
[0028] The drive unit 5 is a drive motor 12 mounted on the horizontal lifting beam 7. A drive gear 13 is mounted on the output shaft of the drive motor 12, and the drive gear 13 is located directly above the driven gear 11. A transmission chain 14 connects the drive gear 13 and the driven gear 11. When the drive motor 12 is working, the drive gear 13 drives the driven gear 11 to rotate, and the driven gear 11 drives the flat support shaft 10 to rotate. When the flat support shaft 10 rotates, it will cause the inner liner 2 to flip. In the initial state, the inner liner 2 is in a vertical state with the upper opening of the inner liner 2 facing upward. At this time, the impact hammer 9 can enter the inner liner 2 and repeatedly hammer the scrapped carbon brush. During the hammering process, the scrapped carbon brush is broken and forms fine particles, which will spread out. If the inner liner 2 is located at the bottom layer, the fine particles at the bottom layer will reduce vibration during subsequent hammering, thus reducing the crushing efficiency. At this time, the drive motor 12 can be controlled to work, causing the inner liner 2 to flip from a vertical state to an inclined state. The upper opening of the inner liner 2 also changes from vertically upward to inclined downward. In the inclined state, the fine particles at the bottom layer of the inner liner 2 will flow and separate from the inner liner 2. Then, the drive motor 12 is reversed, causing the inner liner 2 to return to a vertical state. At this time, only the larger blocks remain in the inner liner 2. The impact hammer 9 is then controlled to enter the inner liner 2 for repeated hammering. This process is repeated several times until all the waste carbon brushes are turned into fine particles and separated from the inner liner 2, thus achieving the crushing of the waste carbon brushes.
[0029] The inner liner 2 includes a cylindrical body 15, with a hemispherical cover 16 fixed to the bottom of the cylindrical body 15. A strip-shaped opening is provided along the length of the cylindrical body 15, with both ends closed. An expansion cover 26 is fitted at the strip-shaped opening. The expansion cover 26 consists of two parts: a main body 17 with a U-shaped cross-section, and an end cover 18 with an area half that of the hemispherical cover 16. The end cover 18 is fixed to both ends of the main body 17. Holes 19 are arranged in an array on the main body 17. Initially, the inner liner 2 is vertical, allowing a discarded carbon brush to be inserted into the inner liner 2 through the top opening. At this time, the discarded carbon brush is located inside the hemispherical cover 16. The impact hammer 9 is then controlled to enter the inner liner 2 and impact the discarded carbon brush inside the hemispherical cover 16. Waste carbon brushes are hammered. After several blows, the impact hammer 9 is moved out of the inner liner 2. Then, the inner liner 2 is flipped from a vertical position to an inclined position, meaning the horizontal height of the main body 17 is lower than the horizontal height of the hemispherical cover 16. During this process, the crushed waste carbon brushes will flow from the hemispherical cover 16 into the main body 17 as the inner liner 2 flips. Some fine particles that meet the requirements will flow out through the holes 19 of the main body 17, while larger, non-compliant pieces remain in the inner liner 2. The inner liner 2 is then flipped back to a vertical position, at which point the horizontal height of the main body 17 is greater than the horizontal height of the hemispherical cover 16. The impact hammer 9 is then re-entered into the inner liner 2 to strike. This avoids the influence of the fine fragments at the bottom on the impact force and increases the crushing efficiency.
[0030] Meanwhile, limit rods 20 are symmetrically installed at the bottom of the inner liner 2. Arc-shaped rail grooves 21 are respectively provided on the two side walls of the housing 1. The arc-shaped rail grooves 21 and the circular groove are on the same side wall. The end of the limit rod 20 fits in the arc-shaped rail groove 21 and can slide in the arc-shaped rail groove 21. When the inner liner 2 is in a vertical state, the limit rod 20 is located at the lower end of the arc-shaped rail groove 21. When the inner liner 2 is in an inclined state, the limit rod 20 is located at the higher end of the arc-shaped rail groove 21. The flat support shaft 10 is located on the arc center of this arc-shaped rail groove 21. In this way, the inner liner 2 can always maintain a stable state during the flipping process, thus improving stability.
[0031] When the inner liner 2 is tilted, fine particles that meet the requirements will flow out from the holes 19 of the main body 17. Therefore, a storage drawer 22 is provided below the inner liner 2. A rectangular slot 23 is opened on the outside of the container 1. The storage drawer 22 is inserted into the container 1 through the rectangular slot 23, and the storage drawer 22 is slidably connected to the inner wall of the container 1. The storage drawer 22 is provided with a pull ring, which can be used to pull the storage drawer 22 out to separate it from the container 1. A bottom support plate 24 is provided at the upper end of the storage drawer 22. The two ends of the bottom support plate 24 are connected to the inner wall of the container 1, and the bottom support plate 24 is perpendicular to the horizontal hanging. With beam 7 in place, when the inner liner 2 is in a vertical position, the bottom support plate 24 contacts the bottom of the hemispherical cover 16. The impact hammer 9 enters the inner liner 2 and hammers the waste carbon brushes inside the hemispherical cover 16. The bottom support plate 24 can support the bottom of the hemispherical cover 16 and distribute the force on the hemispherical cover 16. At this time, a feeding channel 25 is opened on one side of the bottom support plate 24. When the inner liner 2 is tilted, the feeding channel 25 is located directly below the main body 17. The fine particles flowing out from the holes 19 of the main body 17 will directly pass through the feeding channel 25 and fall into the storage drawer 22, so that the fine particles can be collected.
[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
