[0025] Through the above-mentioned mode of setting, the dust screen 93 is arranged in the outside of the frame groove 92, which can filter the dust in the air when ventilating and heat dissipation, prevent the dust from entering the inside of the soundproof cover 8, and maintain the stability of the working environment of the vibrating motor 11 inside.

[0026] In the present mode, a plurality of shaft seats 2 are fixedly installed in the side of the vibrating plate 1, the adapter rod 3 is rotatably installed in the inside of the shaft seat 2, and the connecting assembly 4 is arranged on the upper side of the adapter rod 3.

[0027] Through the above-mentioned mode of setting, the connecting assembly 4 is rotatably arranged with the vibrating plate 1 through the rotation of the adapter rod 3 and the shaft seat 2.

[0028] In the present mode, the connecting assembly 4 includes the long slot 41 and the sliding cover 42, the long slot 41 is fixedly installed on the upper side of the adapter rod 3, the sliding cover 42 is slidably connected with the long slot 41, a plurality of dampers 43 are fixedly connected between the sliding cover 42 and the long slot 41, and the shock absorbing spring 44 is sleeved on the outside of the damper 43.

[0029] Through the above manner, the combination of the damper 43 and the damping spring 44 in the connecting assembly 4 is arranged, so that the vibration generated by the vibrating plate 1 is transmitted to the long groove 41, and then the damping effect of the damper 43 and the damping spring 44 is used to weaken the vibration transmitted to the sliding cover 42.

[0030] In the present manner, the connecting rod 5 is symmetrically fixedly installed on the upper side of the sliding cover 42, the handrail 6 is fixedly connected to the upper end of the connecting rod 5, and the rubber sleeve 7 is sleeved on the outer side of the handrail 6.

[0037] Through the above manner, due to the wave-shaped arrangement of the heat dissipation channel 95, the normal circulation of air is blocked, so that when the heat dissipation fan 12 drives the circulation of air, the circulation speed of air inside the soundproof cover 8 is improved, and the heat dissipation efficiency is improved, so that the heat dissipation requirement of the vibration motor 11 is met.

[0038] The working principle of the concrete vibrating flat plate vibrator with low noise provided by the present application is as follows:

[0039] In use, the handrail 6 drags the device to the construction vibration position, and then the vibration motor 11 and the cooling fan 12 are started. When the vibration motor 11 works, high-frequency vibration is generated by the motor driving eccentric block, which drives the vibration plate 1 to vibrate. The vibration plate 1 transmits the vibration wave to the concrete surface, so that the internal particles of the concrete are rearranged, the bubbles and voids are removed, and the dense effect is achieved. When the cooling fan 12 operates, the air circulation rate inside the sound insulation cover 8 is accelerated, thereby enhancing the heat dissipation effect of the vibration motor 11. The noise generated by the vibration motor 11 when working is absorbed by the internal sound insulation plate 84 inside the sound insulation cover 8. In addition, the noise transmitted to the air is absorbed by the sound-absorbing sponge block 94 when passing through the inside of the heat dissipation channel 95, thereby greatly weakening the noise transmitted to the outside when the vibration motor 11 works.
