Description

Technical Field

[0001] This utility model relates to the field of vibrator technology, and in particular to an adjustable frequency double eccentric wheel hydraulic vibrator. Background Technology

[0002] A vibrator is a mechanical device that uses an eccentric device to generate vibration. It is widely used in electric screening applications. When screening, the eccentric wheel rotates, which drives the screen plate to vibrate. During screening, the motor drives the eccentric wheel to rotate, which in turn drives the screen plate to vibrate repeatedly.

[0003] There are two types of eccentric screening. One type uses a single eccentric wheel at the center of the screen plate to drive the screen plate to screen. The other type uses two sets of eccentric wheels to rotate, thereby driving the screen plate to screen. The double eccentric wheel type uses one large and one small eccentric wheel to screen.

[0004] However, while double eccentric wheels provide good screening performance, different eccentric wheels of different sizes are required for screening different materials. This necessitates bolt-down replacement, resulting in slow efficiency. Therefore, this invention proposes an adjustable frequency double eccentric wheel hydraulic vibrator. Utility Model Content

[0005] The purpose of this invention is to address the problem that while double eccentric wheels provide good screening performance, different sizes of eccentric wheels need to be replaced when screening different materials, requiring bolt disassembly for replacement, which results in slow efficiency.

A positioning plate is slidably connected to the outside of the sliding rod away from the push plate, and a connecting rotating rod is fixedly connected inside the positioning plate.

[0008] Optionally, a support plate is rotatably connected to the outside of the connecting rotating rod. The support plate is fixedly connected to the base platform near the vibrating spring. Push springs are fixedly connected to the opposite side of the push plate and the positioning plate. Multiple sets of push springs are arranged in a circumferential array between the push plate and the positioning plate. The push springs are disposed outside the sliding rod.

[0009] Optionally, a positioning block is fitted inside the embedding groove on the side of the eccentric wheel body away from the push block. A bonding plate is fixedly connected to the side of the positioning block away from the embedding groove. A driving component is provided on the side of the bonding plate away from the positioning block.

An installation block is fitted inside the embedding groove opened in the eccentric wheel body. An installation component is provided on the side of the installation block away from the eccentric wheel body. The installation component is used to fix the eccentric wheel body.

[0012] Optionally, the mounting assembly includes a mounting plate fixedly connected to the side of the mounting block away from the embedding groove, and bolts are rotatably connected inside the mounting plate.

[0013] Optionally, the connecting rotating rod has a threaded hole at one end near the eccentric wheel body, and the bolt is rotatably connected inside the threaded hole.

[0014] In summary, this application includes at least one of the following beneficial technical effects: This utility model uses a method of embedding positioning blocks, pushing blocks, and mounting blocks into the embedding groove opened in the eccentric wheel body to install the embedding groove. The bolt is rotated and installed in the threaded hole, which can ensure the stability of the eccentric wheel body when it is installed outside the connecting rotating rod and on one side of the connecting rotating rod. This increases the convenience of installing and disassembling the eccentric wheel body and improves the efficiency of disassembling and installing the eccentric wheel body.

[0022] Example like Figures 1 to 4 As shown, this utility model proposes an adjustable frequency double eccentric wheel hydraulic vibrator, including a base platform 1. Vibration springs 2 are fixedly connected to the top of the base platform 1. There are four sets of vibration springs 2 arranged in a rectangular array, allowing for different angle changes. A spherical rotating rod 3 is fixedly connected to the end of the vibration springs 2 away from the base platform 1. A vibrating plate 4 is fixedly connected to the end of the spherical rotating rod 3 away from the vibration springs 2. The vibrating plate 4 can change angles by relying on the spherical rotating rod 3. An eccentric wheel body 10 is abutted against the bottom of the vibrating plate 4. The eccentric wheel body 10 has two sets arranged symmetrically. The two sets of eccentric wheel bodies 10 are configured to rotate synchronously or asynchronously. The eccentric wheel bodies 10 have embedded grooves 9 on both sides, and there are multiple sets of embedded grooves 9 arranged in a circumferential array. A push block 11 is embedded in one of the embedded grooves 9. The push block 11 can push the eccentric wheel body 10 to rotate inside the embedded groove 9. A push plate 12 is fixedly connected to the end of the push block 11 away from the embedded groove 9. The push plate 12 can stably embed the push block 11 inside the embedded groove 9. A linkage component is provided on the side of the push plate 12 away from the push block 11. The linkage component is used to connect the two sets of eccentric wheel bodies 10.

[0023] For further details, please refer to Figure 3 and Figure 4The linkage component includes a sliding rod 13, which has multiple sets arranged in a circular array on the side of the push plate 12 away from the push block 11. A positioning plate 15 is slidably connected to the outside of the sliding rod 13 away from the push plate 12. The sliding rod 13 can slide along the inside of the positioning plate 15 to ensure that the push plate 12 can push the push block 11 into the embedding groove 9. A connecting rotating rod 21 is fixedly connected inside the positioning plate 15. The rotation of the connecting rotating rod 21 will drive the sliding rod 13 and the push plate 12 to rotate. A support plate 20 is rotatably connected to the outside of the connecting rotating rod 21. The support plate 20 can... To ensure stable rotation of the connecting rotating rod 21, the support plate 20 is fixedly connected to the base 1 on the side near the vibration spring 2. The support plate 20 can support the connecting rotating rod 21. The push plate 12 and the positioning plate 15 are fixedly connected to the opposite side of the push plate 12 and the positioning plate 15. The push spring 14 can push the push plate 12 to fit against the eccentric wheel body 10. There are multiple sets of push spring 14 arranged in a circumferential array between the push plate 12 and the positioning plate 15. The multiple sets of push spring 14 have a greater thrust. The push spring 14 is set outside the sliding rod 13. The push spring 14 can assist the sliding rod 13 in extension and retraction.

[0024] In addition, please see Figures 2 to 4 One set of eccentric wheel bodies 10 has a positioning block 8 embedded in the groove 9 on the side away from the push block 11. The positioning block 8 is fixedly connected to the side away from the groove 9. The mounting plate 7 can be embedded in the groove 9 and connected to the eccentric wheel body 10 by the positioning block 8. A drive component is provided on the side of the mounting plate 7 away from the positioning block 8. The drive component is used to drive the eccentric wheel body 10 and the connecting rotating rod 21 to rotate. The drive component includes a motor 6. The output end of the motor 6 is fixedly connected to the side of the mounting plate 7 away from the positioning block 8. The motor 6 can drive the mounting plate 7 to drive the positioning block 8 and the eccentric wheel body 10 to rotate. The eccentric wheel body 10 drives the push plate 12 to drive the sliding rod 13 and the positioning plate 15 to rotate by the push block 11, so that the connecting rotating rod 21 rotates synchronously. A support block 5 is fixedly connected to the outside of the motor 6. The support block 5 is fixedly connected to the side of the base 1 near the vibration spring 2. The support block 5 can support the motor 6.

[0025] For further details, please refer to Figure 2 , Figure 3 and Figure 5Another set of eccentric wheel bodies 10 are fitted outside the connecting rotating rod 21. An installation block 18 is fitted inside the embedding groove 9 opened in the eccentric wheel body 10. The connecting rotating rod 21 will drive the eccentric wheel body 10 to drive the installation block 18 to rotate. An installation component is provided on the side of the installation block 18 away from the eccentric wheel body 10. The installation component is used to fix the eccentric wheel body 10. The installation component includes an installation plate 17. The installation plate 17 is fixedly connected to the side of the installation block 18 away from the embedding groove 9. The installation plate 17 can install the eccentric wheel body 10 outside the connecting rotating rod 21 through the installation block 18. A bolt 19 is rotatably connected inside the installation plate 17. A threaded hole 16 is opened at the end of the connecting rotating rod 21 near the eccentric wheel body 10. The bolt 19 stably fixes the installation plate 17 through the threaded hole 16. The bolt 19 is rotatably connected inside the threaded hole 16.

[0026] In this embodiment, when in use, the motor 6 supported by the support block 5 is started, so that the motor 6 drives the bonding plate 7 to rotate. In this way, the bonding plate 7 can drive the positioning block 8 to drive the eccentric wheel body 10 to rotate inside the embedding groove 9. The embedding groove 9 on the other side of the eccentric wheel body 10 will drive the push block 11 and the push plate 12 to rotate. In this way, the push plate 12 can drive the sliding rod 13 and the positioning plate 15 to rotate, so that the connecting rotating rod 21 can rotate under the support of the support plate 20.

[0027] When the connecting rotating rod 21 rotates, it will drive another eccentric wheel body 10 to rotate, thereby pushing the two sets of eccentric wheel bodies 10 to the bottom of the vibrating plate 4. In this way, the vibrating plate 4 will drive the spherical rotating rod 3 to stretch the vibration spring 2, and the base platform 1 will drive the spherical rotating rod 3 and the vibrating plate 4 to reset at the top of the base platform 1. Furthermore, the vibrating plate 4 can vibrate at different angles by relying on the spherical rotating rod 3, so that the vibrating plate 4 can be used for screening.

[0028] When using different materials, the eccentric wheel body 10 needs to be replaced. At this time, the eccentric wheel body 10 near the motor 6 pulls the push plate 12, causing the push plate 12 to drive the sliding rod 13 to slide along the inside of the positioning plate 15. In this way, the push plate 12 will squeeze the sliding rod 13, thereby causing the push plate 12 to drive the push block 11 to disengage from the inside of the eccentric wheel body 10. Then, the eccentric wheel body 10 can be removed from the outside of the positioning block 8 for replacement. During replacement, the new eccentric wheel body 10 is embedded in the outside of the positioning block 8 by the embedding groove 9, and then the push spring 14 pushes the push plate 12 to drive the push block 11 to embed into the embedding groove 9, thereby stably installing the eccentric wheel body 10.

[0029] When it is necessary to disassemble and replace another eccentric wheel body 10, rotate the bolt 19 to disengage it from the mounting plate 17, the eccentric wheel body 10, and the threaded hole 16. Then, the mounting plate 17 can be used to disengage the mounting block 18 from the embedded groove 9. The eccentric wheel body 10 can then be removed from the outside of the push block 11. The new eccentric wheel body 10 is then embedded in the outside of the push block 11. The eccentric wheel body 10 is pushed into the connecting rotating rod 21. The mounting plate 17 is then installed by embedding the mounting block 18 into the embedded groove 9. The bolt 19 is rotated along the mounting plate 17 and the threaded hole 16 of the eccentric wheel body 10 to install the bolt 19. This completes the replacement of the other eccentric wheel body 10.

[0030] It should be noted that this device uses the positioning block 8, pushing block 11 and mounting block 18 to embed into the embedding groove 9 opened in the eccentric wheel body 10 to install the embedding groove 9. The bolt 19 is rotated and installed in the threaded hole 16, which can ensure the stability of the eccentric wheel body 10 when it is installed outside the connecting rotating rod 21 and on one side of the connecting rotating rod 21. This increases the convenience of installing and disassembling the eccentric wheel body 10 and improves the efficiency of disassembling and installing the eccentric wheel body 10.

[0031] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
