Problems solved by technology

Both the planetary vibrator and the eccentric vibrator are driven by a flexible shaft during the working process. The flexible shaft rubs against the shell to generate heat during high-speed rotation, and both the excitation shaft and the eccentric shaft need bearings to provide support. Severe heat generated during rotation, the heat generated during the working process will spread to other structural parts, which accelerates the aging of internal rubber oil seal parts and shortens the service life of the equipment
In addition, whether it is driven by a gasoline engine or an electric motor, it will bring a lot of inconvenience. The gasoline engine needs to be refueled regularly, and at the same time, it will generate noise and exhaust pollution during operation; if it is driven by a motor, the laying of wires in a complex construction environment will increase electric shock. Risk of Leakage

Embodiment Construction

[0026] In order to clearly illustrate the technical features of this solution, the specific implementation of the present invention will be further described below based on the drawings.

[0027] Such as Figure 1~Figure 3 As shown, a pneumatic plug-in concrete vibrator is characterized in that it includes a rod head vibration mechanism, a connecting pipe assembly, a switch mechanism and a lubrication mechanism;

[0028] The rod head vibration mechanism includes a shell, a central shaft 1, an eccentric rotating sleeve 2 and a support sleeve 3. The shell is made of 45# steel, and the shell includes a rod body 32 and a rod tip 33 that are screwed together. The end of 33 is provided with a spherical surface 34; the central shaft 1 is provided with an air chamber 4, the inlet of the air chamber 4 is set at the rear end of the central shaft 1, and the outlet of the air chamber 4 is set on the side of the central shaft 1. The air chamber 4 is provided with a sliding plate 5 capable of c...

Abstract

The invention relates to the technical field of building machines, in particular to a pneumatic inserted type concrete vibrator. The pneumatic inserted type concrete vibrator comprises a bar head vibrating mechanism, a connecting pipe assembly, a switch mechanism and a lubricating mechanism. Compared with the prior art, the pneumatic inserted type concrete vibrator has the beneficial effects that noise is low, energy conversion efficiency is high, cleanliness and safety are achieved, the service life is long, use is convenient, and lubricating and maintaining are easy.

Description

Technical field [0001] The invention relates to the technical field of construction machinery, in particular to a pneumatic plug-in concrete vibrator. Background technique [0002] The plug-in concrete vibrator is a widely used equipment in the construction industry. It eliminates the gap between concrete through vibration, makes the concrete compact, and improves the strength of the concrete structure. The current plug-in concrete vibrators are mainly divided into two types according to structural principles: planetary vibrators and eccentric planetary vibrators. [0003] Planetary vibrator is driven by a gasoline engine or a motor through a flexible shaft to make a planetary rotation in the shell. The shell is vibrated by the impact of the exciting shaft on the shell. This kind of vibrator has high noise and low energy conversion rate. . The eccentric vibrator is driven by a gasoline engine or a motor through a flexible shaft to rotate an eccentric shaft, and the throwing power...
