Description

FIG. 2

The invention relates to earth moving machines with an active tool and can be used in the construction of rippers for the development of durable soils.

The purpose of the invention is to increase the efficiency of loosening due to an increase in the amplitude of tooth oscillations.

1 shows a vibratory ripper general view; FIG. 2 is a diagram of an ultra-sound hydrodynamic vibrator with a loosening tooth.

Vibrating ripper includes basic tire 1, suspension. 2 with stand 3, vibrated on its bottom

A rator 4, on the case 5 of which the hollow loosened tooth 6 is coaxially mounted, with the possibility of longitudinal movement along the body of the vibrator covered by it.

The vibrator is made of an ultrasonic hydrodynamic radiator 7 with a diffuser 8 at the outlet and from a convex diaphragm 9 fixed on the front side of the diffuser, which is connected to the tooth by means of strong articulated joints 10.

In the end part of the diffuser there are conically converging apertures 11, which connect the cavity of the radiator diffuser with the cavity of the tooth, which is by means of branch holes made in the housing of the vibrator; channels 12 is connected to the drain through the opening 13. Through the axial channel 1k of the radiator, the working fluid is supplied from the hydraulic system of the base machine. The drain is also connected to this system.

For the possibility of mounting and dismounting a loosening tooth, it is made of vuh parts — anterior I5 and a posterior 16, connected by a thread 17.

Vibrating ripper works as follows.

A rack 3 with a loosening tooth 6 and a vibrator 4 is lowered onto the ground by means of the suspension 2 and, in the course of the movement of the base machine 1, is buried in the ground. The fluid under pressure, created by the hydraulic system of the base machine 1, is fed through the axial channel 14 of the housing 5 to the confusion-diffuser zone of the ultrasonic cavitation arising from the interaction of the fluid flow with a spherically concave

in relation to it, a diaphragm 9 fixed on the end diffuser part of the body 5 and being a reflector of the flow directly in the zone of intense generated ultrasonic frequency oscillations transmitted by the loosening tooth 6 connected by rigid connections IO to the diaphragm 9. channels 12 and through the hole 13 into the hydraulic system of the base machine.

To balance the pressure on the back side of the diaphragm in order to increase reliability by preventing its rupture, as well as to more efficiently transfer energy, the internal floor of the loosening tooth is filled with fluid fed through holes 11, conically converging to the shape of which contributes to continuity of flow, ensuring the most stable mode of operation of the vibrator.
