Problems solved by technology

[0002] In the prior art, the low-noise concrete vibrator generally uses a hose to transmit torque, and since the maximum rotational speed of the hose to transmit torque is limited by its material and other aspects, the concrete vibrator in the prior art generally has vibration force. Defects such as failing to meet the requirements and inability to compact the concrete, such as the Chinese invention patent CN2259984 issued by the Chinese Patent Office on August 20, 1997, disclose a low-noise concrete vibrating rod. It is composed of the front end cover and rear end cover at both ends of the rod shell and the eccentric shaft installed in the rod shell through bearings. Although the concrete vibrating rod reduces the noise generated during vibration, it also has the above-mentioned insufficient vibration force and cannot Tamping concrete etc.

Embodiment Construction

[0018] see figure 1 , as an embodiment of the present invention, the low-noise concrete vibrating rod as shown in the figure includes a hollow vibrating body 1, and an eccentric shaft 2 is rotatably installed inside the vibrating body 1, and the vibrating body 1 One end of the transmission device 3 is installed, and the transmission device 3 includes a power input shaft 35 and an output shaft, and the output shaft of the transmission device 3 is connected with the eccentric shaft 2 and drives the eccentric shaft 2 to rotate at a high speed; The other end of the vibrating body 1 is equipped with a front end cover 4, thereby closing this end of the vibrating body 1, which can effectively prevent concrete and dust from entering the vibrating body 1.

[0019] Such as figure 1 As shown in , the transmission device 3 includes a casing 31 and a speed changer installed in the casing 31, the speed changer includes a ring gear 32, a sun gear shaft 33 located in the middle of the ring g...

Abstract

A low-noise poker vibrator for concrete is composed of a hollow vibrating cylinder, a rotary eccentrical shaft, and a speed variator consisting of a power input axle and an output axle coupled with said eccentrical shaft. Its advantages are low noise and high vibration force.

Description

Technical field: [0001] The invention relates to a building construction apparatus, in particular to an improved concrete vibrating rod. Background technique: [0002] In the prior art, the low-noise concrete vibrator generally uses a hose to transmit torque, and since the maximum rotational speed of the hose to transmit torque is limited by its material and other aspects, the concrete vibrator in the prior art generally has vibration force. Defects such as failing to meet the requirements and inability to compact the concrete, such as the Chinese invention patent CN2259984 issued by the Chinese Patent Office on August 20, 1997, disclose a low-noise concrete vibrating rod. It is composed of the front end cover and rear end cover at both ends of the rod shell and the eccentric shaft installed in the rod shell through bearings. Although the concrete vibrating rod reduces the noise generated during vibration, it also has the above-mentioned insufficient vibration force and cann...
