Description

Technical Field

[0001] This application relates to the field of mixer technology, and in particular to a noise-reducing vibration compaction device. Background Technology

[0002] The cement mortar compaction device is a piece of equipment used to make strength test blocks. The mixed cement mortar is introduced into the molding mold on the compaction device, and the cement slurry in the molding mold is compacted by the compaction device. Finally, the mold is removed to obtain the test block.

[0003] Existing compaction devices typically include a compaction table, a vibrating component, and a control system. The compaction table is equipped with a molding die for filling cement slurry. The vibrating component typically includes a synchronous motor and a cam. During operation, the control system drives the motor to rotate the cam, which in turn pushes the compaction table upward. After reaching a set value, the table falls freely, generating vibration that compacts the cement mortar under the action of force.

[0004] However, during the compaction process, the cam part constantly impacts the contact area with the compaction table, resulting in significant noise generated by the compaction device during operation. Over a long period of use, this can easily affect the operator's hearing system, indicating a clear deficiency. Utility Model Content

[0005] In order to reduce the adverse effects of the vibration compaction device on the operator's hearing system, this application provides a noise-reducing vibration compaction device.

[0006] The noise-reducing vibration compaction device provided in this application adopts the following technical solution:

[0007] A noise-reducing vibration compaction device includes a base, on which a compaction table and a vibration component are disposed. A soundproof shell is disposed on the base, and the interior of the soundproof shell is filled with sound-absorbing cotton. The soundproof shell covers the outer surface of the compaction table. An operating door is hinged to the top of the soundproof shell. A sound-insulating layer is disposed on the surface of the operating door facing the base. The operating door is fixed to the soundproof shell by a latch.

[0008] By adopting the above technical solution, the worker opens the operating door to load materials, and closes the operating door with the latch after loading is completed. This makes the vibration table inside a sealed environment composed of the soundproof shell and the operating door. When the vibration table generates a lot of noise, the sound-absorbing cotton and sound insulation layer effectively absorb and block the noise, thereby reducing the noise transmitted to the outside world and reducing the adverse effects of the vibration device on the operator's hearing system.

[0009] Optionally, the outer surface of the soundproof shell is provided with a heat dissipation channel, which is connected to the interior of the soundproof shell, and multiple sound-absorbing panels for absorbing noise are evenly arranged at equal intervals in the heat dissipation channel.

[0010] By adopting the above technical solution, the heat generated by the vibration compaction device during operation is dissipated through the heat dissipation channel, reducing the possibility of the equipment's performance and lifespan being affected by overheating. At the same time, multiple sound-absorbing panels can absorb the noise transmitted to the heat dissipation channel in a secondary manner, further enhancing the sound insulation and noise reduction effect while ensuring the normal realization of the heat dissipation function, and ensuring that the device operates stably in a good heat dissipation and low-noise environment.

[0011] Optionally, the sound-absorbing panel has a broken cross-section.

[0012] By adopting the above technical solution, the sound-absorbing panel is arranged in a zigzag pattern, which can extend the movement path of noise and increase the contact time between noise and the sound-absorbing panel, thereby improving the sound absorption effect of the sound-absorbing panel and further reducing the noise transmitted to the outside world.

[0013] Optionally, the outer surface of the soundproof shell is provided with a connecting ring, which is detachably connected to the base via a connecting assembly.

[0014] By adopting the above technical solution, the connection ring and connection components enable the detachable connection between the soundproof shell and the operating door and the base. When the soundproof shell is damaged or the vibration table needs maintenance and repair, the soundproof shell can be easily removed, improving the convenience of maintenance for workers.

[0015] Optionally, the connecting assembly includes a plurality of connecting bolts, which are evenly arranged circumferentially on the connecting ring. The connecting bolts pass through the connecting ring and are threadedly engaged with the base.

[0016] By adopting the above technical solution, when installing the soundproof shell, the worker places the connecting ring on the base, and then tightens multiple connecting bolts on the base with an electric screwdriver, thereby installing the soundproof shell on the base; when disassembling, the worker unscrews multiple connecting bolts from the base with an electric screwdriver, and then lifts the connecting ring upwards to detach it from the base, thereby disassembling the soundproof shell.

[0017] Optionally, the connecting assembly includes multiple sets of fixing members disposed on the bottom surface of the connecting ring. Each set of fixing members includes multiple elastic clips evenly distributed in a circumferential shape. Each elastic clip is provided with a hook portion. The multiple elastic clips are clustered together in their natural state. The base has receiving grooves that correspond one-to-one with the multiple sets of fixing members. The inner sidewall of the receiving groove has a fixing groove that engages with the hook portion. The connecting ring is provided with an operating component. The operating component overcomes the elastic force of the elastic clips and drives the hook portion to abut against the inner sidewall of the fixing groove.

[0018] By adopting the above technical solution, when installing the soundproof shell, the worker places the connecting ring on the base and ensures that the fixing part is inserted into the corresponding receiving groove. Then, the worker uses the operating component to overcome the elastic force of the elastic strip, causing the hook part to abut against the inner side wall of the fixing groove, thus connecting the connecting ring to the base and installing the soundproof shell on the base. When disassembling the soundproof shell, the worker first cancels the action of the operating component on the elastic strip. The elastic strip gathers under its own elastic force, at which point the hook part disengages from the fixing groove and retracts into the receiving groove. The worker then lifts the connecting ring upwards, causing the fixing part to disengage from the receiving groove, thus disassembling the soundproof shell.

[0019] Optionally, the connecting ring has an annular groove, and the inner wall of the annular groove has a vertical groove. The operating component includes a screw rotatably connected in the vertical groove. The screw is threaded with a drive ring that slides in the annular groove. The drive ring is provided with drive posts that correspond one-to-one with the multiple sets of fixing parts. The connecting ring has a clearance groove that slides in the drive posts. Multiple elastic clips are evenly arranged on the outer periphery of the drive posts. When the drive post passes between the multiple elastic clips and abuts against the bottom wall of the receiving groove, the hook portion abuts against the inner wall of the fixing groove.

[0020] By adopting the above technical solution, when the fastener is inserted into the receiving groove, the worker rotates the screw forward to make the drive ring move downward. The drive ring drives the drive column to pass through the clearance groove and multiple elastic clips and extend into the receiving groove. During the movement of the drive column, the drive column overcomes the elastic force of the elastic clips, causing multiple elastic clips to expand outward synchronously. The hook part continuously approaches the fixing groove. When the drive ring moves to the bottom of the ring groove, the drive column abuts against the bottom wall of the receiving groove, and the hook part hooks onto the inner side wall of the fixing groove, thereby realizing the installation of the sound insulation shell.

[0021] During disassembly, rotating the screw in the opposite direction moves the drive ring upward, causing the drive pin to disengage from the elastic clip. The elastic clip then returns to its closed state under its own elastic force, and the hook part disengages from the fixing groove, allowing for quick disassembly of the sound insulation shell. The design of the operating components allows workers to quickly fix and detach multiple fasteners simply by turning the screw, further improving the convenience of disassembly and assembly.

[0022] Optionally, the soundproof shell has grip grooves on both opposite sides for easy holding.

[0023] By adopting the above technical solution, when installing or disassembling the soundproof shell, operators can more easily apply force and control it by holding the grip groove, further improving the convenience of operation.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. This application uses a soundproof shell, sound-absorbing cotton, sound insulation layer and sound-absorbing panel. Workers open the operating door to load materials, and close the operating door with a latch after loading. This makes the vibratory table inside a sealed environment composed of the soundproof shell and the operating door. When the vibratory table generates a lot of noise, the sound-absorbing cotton and sound insulation layer effectively absorb and block the noise, thereby reducing the noise transmitted to the outside world and reducing the adverse effects of the vibratory device on the hearing system of the operator.

[0026] 2. This application achieves a detachable connection between the soundproof shell and the operating door and the base by setting a connecting ring and connecting components. When the soundproof shell is damaged or the vibration table needs maintenance and repair, the soundproof shell can be easily removed, which improves the convenience of maintenance for workers.

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses a noise-reducing vibration compaction device.

[0036] Example 1

[0037] Reference Figure 1 and Figure 2 A noise-reducing vibration compaction device includes a base 1, on which a vibration compaction table 01 for carrying raw materials and a vibration component 02 are installed. The principle by which the vibration component 02 drives the vibration compaction table 01 to vibrate is existing technology and will not be described in detail here.

[0038] Reference Figure 1 and Figure 2 A soundproof shell 2 is detachably connected to the base 1. The soundproof shell 2 is a hollow shell and is filled with sound-absorbing cotton 21. In this embodiment, the sound-absorbing cotton 21 is made of polyester fiber. The porous structure of the polyester fiber can effectively capture and absorb sound waves. An operating door 3 is hinged to the top of the soundproof shell 2. A sound insulation layer 31 is fixedly connected to the surface of the operating door 3 facing the base 1. In this embodiment, the sound insulation layer 31 is a polyurethane foam layer. The operating door 3 is fixed to the soundproof shell 2 by a latch, which can ensure that a tight soundproof space is formed when closed.

[0039] Workers open the operating door 3 to load materials. After loading, the operating door 3 is closed by locking the door. This keeps the vibrating table 01 in a sealed environment consisting of the soundproof shell 2 and the operating door 3. When the vibrating table 01 generates a lot of noise, the sound-absorbing cotton 21 and the sound insulation layer 31 effectively absorb and block the noise, thereby reducing the noise transmitted to the outside world and minimizing the adverse effects of the vibrating device on the operator's hearing system.

[0040] Reference Figure 1 and Figure 2 A heat dissipation channel 4 is fixedly connected to the outer surface of the soundproof shell 2. The heat dissipation channel 4 is connected to the interior of the soundproof shell 2. Multiple sound-absorbing panels 41 are evenly installed at equal intervals along the length of the heat dissipation channel 4. In this embodiment, the sound-absorbing panels 41 are made of rock wool. The sound-absorbing panels 41 are used to absorb noise. The cross-section of the sound-absorbing panels 41 is zigzag-shaped, thereby extending the movement path length of the noise and increasing the contact time between the noise and the sound-absorbing panels 41, thereby improving the sound absorption effect of the sound-absorbing panels 41.

[0041] The heat generated during the operation of the vibration compaction device is dissipated through the heat dissipation channel 4, reducing the possibility of the equipment being affected by overheating and its lifespan. When noise is transmitted into the heat dissipation channel 4, multiple sound-absorbing panels 41 absorb the noise a second time, further enhancing the sound insulation and noise reduction effect while ensuring the normal realization of the heat dissipation function, and ensuring that the device operates stably in a good heat dissipation and low-noise environment.

[0042] Reference Figure 1 and Figure 2The soundproof shell 2 is fixedly connected to the outer surface of the base 1 with a connecting ring 5. The connecting ring 5 is detachably connected to the base 1 through the connecting assembly 6. The connecting assembly 6 includes multiple connecting bolts 61. The multiple connecting bolts 61 are evenly distributed on the outer periphery of the connecting ring 5 at equal intervals. The connecting bolts 61 pass through the connecting ring 5 and are threaded into the base 1.

[0043] Reference Figure 1 and Figure 2 The soundproof shell 2 has grip grooves 22 on both sides of its outer surface for easy gripping.

[0044] When the soundproof shell 2 is damaged or the vibration table 01 needs maintenance, the worker uses an electric screwdriver to unscrew multiple connecting bolts 61 from the base 1 in sequence, and then pulls the connecting ring 5 upward to detach it from the base 1, thereby disassembling the soundproof shell 2. When installing a new soundproof shell 2, first place the connecting ring 5 on the base 1, and finally the worker uses an electric screwdriver to tighten multiple connecting bolts 61 onto the base 1 in sequence, thereby installing the soundproof shell 2. The setting of the connecting ring 5 and the connecting component 6 enables the detachable connection between the soundproof shell 2 and the operating door 3 and the base 1, improving the convenience of worker maintenance.

[0045] The implementation principle of a noise-reducing vibration compaction device in this application embodiment is as follows: the worker opens the operating door 3 to load materials, and after loading is completed, the operating door 3 is closed by the latch. This makes the vibration compaction table 01 inside the sealed environment composed of the sound insulation shell 2 and the operating door 3. When the vibration compaction table 01 generates a lot of noise during operation, the sound-absorbing cotton 21 and the sound insulation layer 31 effectively absorb and block the noise, thereby reducing the noise transmitted to the outside world and reducing the adverse effects of the vibration compaction device on the operator's hearing system.

[0046] Example 2

[0047] Reference Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that the connecting component 6 includes multiple sets of fixing members fixedly connected to the bottom surface of the connecting ring 5. The multiple sets of fixing members are evenly distributed circumferentially on the outer periphery of the connecting ring 5. Each set of fixing members includes multiple elastic clips 62 evenly distributed in a circumferential shape. In this embodiment, the number of elastic clips 62 in each set of fixing members is four. Each elastic clip 62 has a hook portion 621 integrally formed at the end away from the connecting ring 5. Each set of elastic clips 62 is clustered in its natural state. The base 1 has a receiving groove 7 corresponding to each of the multiple sets of fixing members. The cross-sectional area of ​​the receiving groove 7 is larger than the clustered elastic clips 62. The inner side wall of the receiving groove 7 away from the connecting ring 5 has a fixing groove 71 that hooks and cooperates with the hook portion. The fixing groove 71 is an annular groove formed on the outer periphery of the receiving groove 7.

[0048] Reference Figure 4 , Figure 5 and Figure 6 The outer surface of the connecting ring 5 has an annular groove 51, and the inner side wall of the annular groove 51 has a vertical groove 52. An operating component 8 is provided in the annular groove 51 and the vertical groove 52. Specifically, the operating component 8 includes a screw 81 rotatably connected in the vertical groove 52. A drive ring 82 that slides with the annular groove 51 is threaded onto the screw 81. The cross-section of the drive ring 82 and the annular groove 51 is square. The end of the screw 81 extends to the outer surface of the connecting ring 5 and is coaxially fixedly connected to a handwheel (not shown in the figure).

[0049] Reference Figure 4 , Figure 5 and Figure 6 The drive ring 82 is fixedly connected to the surface of the base 1 with drive columns 83 corresponding to multiple sets of fixing parts. The connecting ring 5 is provided with a relief groove 53 that slides with the drive column 83. Multiple relief grooves 53 correspond to and are connected to the receiving groove 7. Multiple elastic clips 62 are evenly arranged on the outer periphery of the drive column 83 in the circumferential direction. When the screw 81 drives the connecting ring 5 to abut against the inner wall of the ring groove 51 near the base 1, the drive column 83 abuts against the inner bottom wall of the receiving groove 7. At this time, the drive column 83 simultaneously opens the multiple elastic clips 62, and the hook part 621 abuts against the inner wall of the fixing groove 71.

[0050] The implementation principle of Example 2 is as follows: When installing the soundproof shell 2, the worker places the connecting ring 5 on the base 1 and ensures that the fixing part is inserted into the corresponding receiving groove 7. Then, the worker rotates the screw 81 in the forward direction to make the drive ring 82 move downward. The drive ring 82 drives the drive column 83 to pass through the clearance groove 53 and multiple elastic clips 62 and extend into the receiving groove 7. During the movement of the drive column 83, the drive column 83 overcomes the elastic force of the elastic clips 62, causing multiple elastic clips 62 to expand outward synchronously. The hook part continuously approaches the fixing groove 71. When the drive ring 82 moves to the bottom of the ring groove 51, the drive column 83 abuts against the inner bottom wall of the receiving groove 7, and the hook part hooks onto the inner side wall of the fixing groove 71, thereby realizing the installation of the soundproof shell 2.

[0051] During disassembly, the screw 81 is rotated in the opposite direction to move the drive ring 82 upward. The drive ring 82 drives the drive column 83 to disengage from the elastic clip 62. The elastic clip 62 returns to its gathered state under its own elastic force, and the hook part 621 disengages from the fixing groove 71. Then, the worker lifts the connecting ring 5 upward to make the fixing part disengage from the receiving groove 7, thus realizing the disassembly of the sound insulation shell 2. The setting of the operating component 8 allows the worker to quickly fix and disengage multiple fixing parts by simply turning the screw 81. The disassembly process does not require turning multiple connecting bolts 61, which further improves the convenience of the worker during disassembly and assembly.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
