Description

Technical Field

[0001] This application relates to the field of concrete vibrator technology, and in particular to a concrete vibrator. Background Technology

[0002] Planetary concrete vibrators are currently the most widely used power tools in the domestic construction industry for vibrating and compacting concrete during the pouring process. Alkali-activated concrete is a new type of green building material, which is generated by the reaction of a precursor containing aluminosilicate with an alkaline solution. When pouring alkali-activated concrete, a high-frequency vibrator is required to achieve the purpose of vibrating and compacting the concrete.

[0003] Chinese Patent Application No. 202322698974.9 discloses an electric flexible shaft planetary concrete vibrator, relating to the field of construction machinery technology. It includes a vibratory motor, a control box fixedly connected to the top of the motor, a connecting mechanism at the right end of the motor, a vibrating rod at the right end of the connecting mechanism, and a heat dissipation base fixedly connected to the bottom of the motor. In this invention, when connecting the vibrating rod head, a connecting sleeve is inserted into the side of the connecting joint. Rotating the rotating gear ring drives the drive wheel to rotate, which in turn drives the threaded rod to rotate, allowing the threaded slider to slide. The sliding block slides in the groove on the side of the sliding plate, causing the sliding plate to move and lock into place on the side of the connecting joint. This facilitates the connection and fixation of the vibrating rod head, improves the connection effect, and makes the concrete vibrator more convenient to use.

However, it is inconvenient to disassemble, clean, or replace the dustproof screen during use, and it is also inconvenient to absorb and reduce vibrations during device operation.

When using the component, to remove, clean, or replace the dust filter, simply rotate the rotating block. The rotation of the rotating block will drive the fixing screw to rotate, which in turn will move the cylindrical rubber fixing block, disengaging it from the fixing hole on one side of the dust filter. Then, you can remove the dust filter from the disassembly and assembly base for cleaning or replacement. The auxiliary rotating rod makes it easy to rotate the rotating block, and the sponge sleeve ensures hand comfort when rotating with force.

[0016] In summary, this application includes the following beneficial technical effects:

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] Please refer to the details. Figure 1-3 The present invention provides the following technical solution: a concrete vibrator, including a base 1, an anti-slip pad 10 fixedly connected to the bottom of the base 1, a heat dissipation component 3 arranged above the base 1, dustproof nets 4 symmetrically arranged on both sides of the heat dissipation component 3, a vibration motor 6 fixedly connected above the heat dissipation component 3, a control box 7 fixedly connected above the vibration motor 6, a connecting mechanism 8 fixedly connected to one end of the vibration motor 6, a vibrating rod 9 fixedly connected to one end of the connecting mechanism 8, a shock absorption component 2 arranged between the base 1 and the heat dissipation component 3, and the heat dissipation component 3 and the dustproof nets 4 connected by a convenient disassembly and assembly component 5.

[0025] Specifically, the damping assembly 2 includes a damping seat 21, a damping plate 22, a damping telescopic rod 23, a damping spring 24, a limiting slider 25, a limiting slide rod 26, a damping spring 27, and a connecting assembly 28.

The damping telescopic rods 23 are symmetrically and fixedly connected to both ends below the damping plate 22. The lower part of the damping telescopic rods 23 is fixedly connected to the damping seat 21. Damping springs are uniformly and fixedly connected to the middle of the lower part of the damping plate 22. A shock-absorbing spring 24 is fixedly connected to the bottom of the shock-absorbing seat 21. Limiting sliders 25 are fixedly connected to both sides of the shock-absorbing plate 22. The limiting sliders 25 and the shock-absorbing seat 21 are slidably connected. A limiting slide rod 26 is slidably connected to the middle of the limiting slider 25. The two ends of the limiting slide rod 26 are fixedly connected to the inner wall of the shock-absorbing seat 21 respectively. A second shock-absorbing spring 27 is fixedly connected to one side below the limiting slider 25. The bottom of the second shock-absorbing spring 27 is fixedly connected to the shock-absorbing seat 21. Connecting components 28 are provided on both sides of the shock-absorbing seat 21.

[0026] By adopting the above technical solution, the shock-absorbing plate 22 moves in the shock-absorbing seat 21 to compress the shock-absorbing spring 24, which, together with the damping telescopic rod 23, facilitates the reduction of vibration generated during the operation of the device. At the same time, the movement of the shock-absorbing plate 22 will drive the limiting slider 25 to move on the limiting slider 26, so that the shock-absorbing plate 22 can move stably. Meanwhile, the limiting slider 25 will compress the second shock-absorbing spring 27, resulting in a good shock absorption effect.

[0027] Specifically, the connecting component 28 includes mounting block 281, mounting screw 282, mounting block 283, and mounting screw 284. Mounting block 281 is fixedly connected to both sides of the shock absorber 21, mounting screw 282 is installed in the middle of mounting block 281, mounting blocks 283 are symmetrically and fixedly connected to both ends of the upper part of the shock absorber 22, and mounting screw 284 is installed in the middle of mounting block 283.

[0028] By adopting the above technical solution, the base 1 is connected to the mounting block 281 and then fixed by the mounting screw 282, which facilitates the splicing of the base 1 and the shock absorption component 2. The heat dissipation component 3 is connected to the mounting block 283 and then fixed by the mounting screw 284, which facilitates the splicing of the shock absorption component 2 and the heat dissipation component 3.

[0029] Specifically, the base 1 has a threaded hole on its upper part for mounting screw 282, and the heat dissipation assembly 3 has threaded holes at both ends for mounting screw 284.

[0030] By adopting the above technical solution, the threaded hole and mounting screw 282 cooperate to facilitate the fixing of base 1 and mounting block 281, and the threaded hole and mounting screw 284 cooperate to facilitate the fixing of heat dissipation component 3 and mounting block 283.

[0031] Specifically, the easy-to-assemble / disassemble component 5 includes an assembly / disassembler base 51, a cylindrical rubber fixing block 52, a fixing screw 53, a rotating block 54, an auxiliary rotating rod 55, and a sponge sleeve 56. The heat dissipation component 3 is fixedly connected to the heat dissipation area of ​​the assembly / disassembler base 51. The dustproof mesh 4 is tightly inserted into the interior of the assembly / disassembler base 51. The cylindrical rubber fixing block 52 is tightly inserted into one side of the dustproof mesh 4 inside the assembly / disassembler base 51. The cylindrical rubber fixing block 52 and the assembly / disassembler base 51 are slidably connected. The fixing screw 53 is fixedly connected to one end of the cylindrical rubber fixing block 52. The fixing screw 53 is threadedly connected to the assembly / disassembler base 51. The rotating block 54 is fixedly connected to one end of the fixing screw 53. The auxiliary rotating rod 55 is fixedly connected around the surface of the rotating block 54. The sponge sleeve 56 is fixedly connected to the surface of the auxiliary rotating rod 55.

[0032] By adopting the above technical solution, when it is desired to remove, clean or replace the dustproof net 4, the rotating block 54 is rotated. The rotation of the rotating block 54 will drive the fixing screw 53 to rotate. The rotation of the fixing screw 53 will drive the cylindrical rubber fixing block 52 to move, so that it is disengaged from the fixing hole opened on one side of the dustproof net 4. Then the dustproof net 4 can be taken out from the disassembly and assembly base 51 for cleaning or replacement. The auxiliary rotating rod 55 makes it easy to rotate the rotating block 54. The sponge sleeve 56 makes it easy to keep the hand comfortable when rotating with force.

[0033] Specifically, the two ends of the mounting base 51 are provided with snap grooves, and one side of the dustproof net 4 is provided with a fixing hole that matches the cylindrical rubber fixing block 52.

[0034] By adopting the above technical solution, the setting of the slot makes it easy to remove the dustproof net 4 from the disassembly base 51, and the fixing hole facilitates the tight insertion of the cylindrical rubber fixing block 52 to fix the dustproof net 4.

[0035] The structure and operating principle of the heat dissipation component 3, dustproof net 4, vibration motor 6, control box 7, connecting mechanism 8, and vibrating rod 9 in this utility model are disclosed in an electric flexible shaft planetary concrete vibrator (202322698974.9). Its working principle is as follows: the heat dissipation component 3 includes a support base, heat absorption plate, coolant chamber, cooling pipe, heat dissipation groove, heat exchanger, electric motor, guide fan, connecting shaft, sealing ring, and guide fan; the connecting mechanism 8 includes a connecting joint, connecting sleeve, rotating gear ring, drive wheel, threaded rod, threaded slider, sliding block, and sliding plate. In use, the connecting sleeve is inserted into the side of the connecting joint, and the drive wheel is driven by rotating the gear ring. The rotation causes the threaded rod to slide along the threaded slider, which in turn causes the sliding block to engage with the side of the connecting joint, facilitating the connection and fixation of the vibrator 9. In use, the vibrator 9 is inserted into the concrete, and the vibration motor 6 is started to achieve the purpose of vibrating and compacting the concrete. Simultaneously, the heat-absorbing plate absorbs heat from inside the motor, and starting the electric motor causes the connecting shaft to rotate, driving the guide fan to rotate. This causes the coolant in the cooling chamber to flow through the cooling pipe, thus cooling the heat-absorbing plate and facilitating heat dissipation for the vibration motor 6, thereby extending its service life.

[0036] The working principle and usage process of this utility model: This utility model is used for high-frequency vibration during the pouring of alkali-activated concrete. In use, the vibrating rod 9 and the vibrating motor 6 are connected through the connecting mechanism 8. The vibrating rod 9 is placed in the alkali-activated concrete, and then the vibrating motor 6 is started to achieve the purpose of vibration and compaction of the alkali-activated concrete. During operation, the heat dissipation component 3 facilitates heat dissipation for the vibrating motor 6. During heat dissipation, the dustproof net 4 helps to prevent dust from entering. The dustproof net 4 can be quickly disassembled and cleaned or replaced through the easy disassembly and assembly component 5. The shock absorption component 2 helps to absorb and reduce the vibration during the operation of the device.

[0037] When in use, the shock-absorbing component 2 moves within the shock-absorbing base 21 via the shock-absorbing plate 22, compressing the shock-absorbing spring 24. This, in conjunction with the damping telescopic rod 23, facilitates the reduction of vibrations generated during device operation. Simultaneously, the movement of the shock-absorbing plate 22 causes the limiting slider 25 to move on the limiting slide rod 26, ensuring stable movement of the shock-absorbing plate 22. The limiting slider 25 also compresses the second shock-absorbing spring 27, resulting in effective shock absorption. When in use, the connecting component 28 connects to the base 1 via mounting block 281 and is then secured with mounting screw 282, facilitating the splicing of the base 1 and the shock-absorbing component 2. It also connects to the heat dissipation component 3 via mounting block 283 and is secured with mounting screw 284, facilitating the splicing of the shock-absorbing component 2 and the heat dissipation component 3. This allows the device to effectively absorb and reduce vibrations generated during operation.

[0038] When using the convenient disassembly and assembly component 5, if you want to remove, clean, or replace the dust filter 4, simply rotate the rotating block 54. The rotation of the rotating block 54 will drive the fixing screw 53 to rotate, and the rotation of the fixing screw 53 will drive the cylindrical rubber fixing block 52 to move, causing it to disengage from the fixing hole on one side of the dust filter 4. Then, the dust filter 4 can be removed from the disassembly and assembly base 51 for cleaning or replacement. The auxiliary rotating rod 55 makes it easy to rotate the rotating block 54, and the sponge sleeve 56 keeps your hand comfortable when rotating with force.

[0039] 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.
