Description

The invention relates to vibration technology, in particular to deep vibrators, and can be used in various industries for deep compaction of granular media (concrete mixture, sandy soil, etc.).

Known deep vibration seals, including housing, electric drive and vibration exciter. Practice has shown (for example, at the Kharkov DSK-1, in the Yuzhepetsstroy trust, etc.) that when using vibrators for processing concrete faucets of large thickness, the efficiency and quality of compaction are reduced. Vibrators quickly fail due to wear of rotating parts and overload of electric motors.

(Closest to the proposed device is a vibrating machine, comprising a body in the form of an elastic shell with a tip, filled liquid, and connected to a hydro pulsator.

The purpose of the invention is to increase durability and reliability.

This goal is achieved in that the elastic sheath is made in the form of a rubber-cord pressure sleeve with a rigid tip.

In order to increase the safety of operation and to improve the orientation of the housing in the sealing medium, a guide pin is placed inside the housing.

In order to increase the amplitude of the axial vibrations of the body, part of the elastic shell is made in the form of a bellows.

In order to increase productivity and synchronize operation, the vibrator is made in the form of a series of cylindrical rubber-cord pressure hoses suspended on a common traverse and connected to a common hydraulic pulsator.

The vibrator works as follows. In a simple manner.; 3 :: Y,;:. : - :. - / g: /: - - the engine through the crank mechanism 6 is reciprocated to the piston 5. When the piston 5 moves to the left, the fluid is pumped into the cylindrical rezinokordovaya pressure head sleeve 1, which changes shape - expands in the radial direction, while the tip 2 is carried upward. When the piston 5 moves to the right, the sleeve 1 first restores its shape, then due to rarefaction in the liquid partially collapses (is removed in the radial direction), and the tip 2 moves down. Then the cycle repeats - the system performs spatial vibrations, which are transmitted to the concrete mixture 7 in

compartment 8.::. The implementation of the elastic shell in the form of a cylindrical rubber-cord sleeve 1 with a rigid tip 2. improves the strength and rigidity of the housing

The implementation of the elastic shell part in the form of a bellows 11 (Fig. 3) allows to increase the oscillation amplitude of the vibrator body in the axial direction. :. ; . : The implementation of the vibrator in the form of a series of 12 cylindrical rubber-cord pressure head hoses 1 connected to a common hydraulic pulsator (Fig. 4) suspended on a common traverse allows to increase productivity and synchronize operation. It is possible to create a hydro-pulsator; the donation of fluid in an elastic shell is much greater than 0.5 ... 0.7 MPa (which occurs when using a pneumatic network), which increases the efficiency of vibration exposure to the medium to be processed of large thickness (at great depths counteraction from

concrete mix is substantial) and improves the quality of compaction.
