SU1477854A1 - Working member of vibrated ripper - Google Patents

Abstract

The invention relates to earthmoving machines and can be used in rippers for the development of durable soils. The goal is to increase the efficiency of loosening by using parametric resonance. The working body of the vibrolayer includes parallelogram suspension 1. It is pivotally fixed by means of shock absorbers 5 and 8 of a double-sided strut (C) 9. C 9 mounted loosening tooth 10 and vibrator 11. Fixed C 9 on parallelogram suspension 1 by means of working beam 3 and swing frame (CR) 6. Shock absorbers 5 are located between the working beam 3 and CD 6. Shock absorbers 8 - between C 9 and CD 6. When loosening at a critical depth, the natural frequency of the forced vibrations C 9 is a multiple of the natural frequency of the forced vibrations of the CD 6. This is lead after the first tooth 10 chips in parametric resonance. The amplitude of oscillations of the end of the tooth 10 increases. The energy of a single pulse increases. Ripper productivity increases. 1 il.

Description

The working body of the vibrolayer including 1-JQ of the first few chips loosens the parallelogram suspension 1 with the lift-lower hydraulic cylinder 2, on which the working beam 3 is pivotally fixed. vertical guides 7, in which, by means of vertically oriented shock absorbers 8, a stand 9 is installed with a loosening tooth 10 and vibration exciter 11 rigidly connected to it in the upper part.

The working body works as follows., 25

Using hydraulic cylinder 2 and suspension 1, the loosening tooth 10 is lowered into the working position, which through the post 9 under the action of the force of resistance of the ground to the pressure pushes JQ the swing frame 6, causes it to deviate from the equilibrium position, which causes compression of the upper shock absorbers 5. In at the same time, the rack 9 with the loosening tooth 10 under the action of the disturbing force of the vibration exciter 11, the direction of which coincides with the longitudinal axis of symmetry of the rack 9, makes a reciprocating motion relative to the swinging frame 6 o And o Movement occurs with the frequency of forced oscillations of the vibration exciter 11.

Under the action of the disturbing force of the vibration exciter 11 and the decompression force of the upper shock absorbers 5, the loose tooth 10 is inserted into the ground. When its penetration reaches a depth that is critical for a given tooth shape, a chipping of a certain amount of soil occurs. With this release iO

The new tooth 10 as a whole starts to operate in the parametric resonance mode, and this leads to an increase in the amplitude of its sharp end oscillation. Resonant matching of the system. The exciter 11 - the stand 9 with the loosening tooth 10 with the frequency of chips is carried out with the help of shock absorbers 5 and 8.

The work of the vibro-ripper working unit in the parametric resonance mode increases the energy of a single impulse of the vibration exciter by using the mass of all oscillating parts, which leads to an increase in the amplitude of oscillations of the sharp end of the loosening tooth 10 and increases productivity.
