Description

Concrete vibrator

Technical Field

The invention relates to the field of concrete equipment, in particular to a concrete vibrator.

Background

The concrete vibrator is an electric tool for compacting poured concrete through vibration; concrete vibrators are various in types and are divided into an inner vibrator, an outer vibrator and a surface vibrator according to a vibration transmission mode; the vibrator is divided into an electric type, an internal combustion type and an air-operated type according to the power source of the vibrator, so that the electric type is most widely applied; the vibration frequency of the vibrator is divided into a low frequency type, a medium frequency type and a high frequency type; the vibration generator is divided into an eccentric type and a planetary type according to the principle that the vibrator generates vibration; the existing concrete vibrator is simple in structure and poor in damping effect, and can generate violent vibration when tamping concrete, so that the concrete vibrator is provided.

As a preferred embodiment of the present invention, the lower base is fixedly disposed at the bottom of the fixing base, and the return spring is sleeved on the telescopic rod.

In a preferred embodiment of the present invention, the bottom plate is provided with a magnet, the top plate is also provided with a magnet at a corresponding position, and the magnet at the corresponding position is opposite to the magnetic pole.

In a preferred embodiment of the present invention, the support plate is provided with a mounting seat on an upper end surface thereof, and the motor is disposed on a top end of the support plate through the mounting seat.

The invention has the beneficial effects that:

1. staff starter motor, the motor starts the back, its output shaft can pass through the connecting pipe and transmit to the vibrting spear on, insert the inside of concrete with the vibrting spear, vibration alright with tamp the concrete through the vibrting spear, and simultaneously, the motor is when moving, the vibrations of its production can be transmitted to the carousel through the backup pad, transmit to the roof by the carousel again, behind the roof atress, the base lapse in the drive, and simultaneously, go up and be compressed behind the reset spring atress between base and the lower base, this can cushion partly vibrations, and simultaneously, the magnet that sets up on bottom plate and the roof is relative with the magnetic pole, can produce a mutual repulsion's power between them, this is favorable to guaranteeing the stability at roof both ends, make the motor can not rock about the top of carousel.

2. This device structural design is reasonable, and convenient operation can guarantee concrete vibrator's even running through the damping device who sets up to be convenient for change the direction of vibrator, labour saving and time saving.

The invention makes up for the defects in the background technology to a certain extent.
