Low-noise concrete poker virbrator

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 equipment, in particular to an improved concrete vibrating rod. Background technique: [0002] In the prior art, low-noise concrete vibrating rods generally use hoses to transmit torque, and because the maximum speed of the hose to transmit torque is limited by its materials and other aspects, the concrete vibrating rods in the prior art generally have vibration forces. Defects such as failure to meet the requirements and the inability to tamping concrete. For example, the Chinese Invention Patent CN2259984 authorized and announced by the Chinese Patent Office on August 20, 1997 discloses a low-noise concrete vibrating rod. The front end cover, the 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 insufficient vibration force as described above. Proble...

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.
