The concrete vibrator comprises a power cord (1), a controller (2), and a vibrating rod (3).

A rechargeable, motor built-in, insertion-type concrete vibrator and an operation control method therefor.

A motor built-in, insertion-type concrete vibrator, comprising a power cord (1), a controller (2), a connecting cable, a rubber tube (5), and a vibrating rod (6).

The working time duration of the concrete vibrator can be acquired by means of recharging, thus solving the problem of increased manufacturing costs for the vibrator and of large startup investment for user.

Manufacturing includes, gasoline engine, gasoline generator, gasoline water pumps, gasoline concrete vibrator, gasoline generator with welding, diesel engine, diesel generator, diesel water pump, pressure washer and so on.

Below, the marriage of a tire fitter, a truck rim, a conveyor motor, concrete vibrator and a roller wheel to give birth to our first metal spinning tool ;)

An internal vibrator for compacting concrete comprises an elastically deformable protective and operating tube (2) which is coupled to a vibrating cylinder (1).

The concrete vibrator comprises a power cord (1), a controller (2), and a vibrating rod (3).

A rechargeable, motor built-in, insertion-type concrete vibrator and an operation control method therefor.

The invention relates to a vibration device in a device for producing moulded concrete blocks by compacting a concrete mixture in a mould (FE) and by vibrating said mould.

If the vibrator housing (6) is immersed in concrete (12), the heat produced in the converter housing (2) can be conducted away to the concrete (12).

The invention relates to a device for producing moulded concrete blocks in a moulding machine by actuating a vibration device on a concrete mixture that has been introduced into cavities (FN) of a mould (FE).

The vibrator (11) is constructed from a bimorph vibrator where an electric current varies according to the inner pressure of an object to be measured in contact with the vibrator with a constant AC voltage applied to the vibrator.

The buzzer is usually operated at a constant frequency.

The exciter is attached to the vibrator, and the vibration of the exciter causes the vibrator to vibrate together therewith.
