Description

A resonance tuning machine is designed primarily for moving and sorting bulk materials. The working body of the machine, for example a tray, is associated with an elastic system.

A distinctive feature of the proposed machine is that an elastically oscillating system is used to transfer energy from the vibrator to the tray, consisting of two moving and one fixed masses connected in series through two elastic spring systems. The latter are tuned in such a way that the frequency of oscillation of the system from the action of the disturbing forces of the vibrator is in a certain ratio with the two resonant frequencies of natural oscillations of the system. This ratio determines the form of its forced vibrations.

Thanks to such a device, an increase in the oscillation range of the tray is achieved, regardless of the stroke of the vibrator.

One of the moving masses can be associated with the working body.

(tray), receiving vibrations from the vibrator directly from the side of another moving mass or from the side of a fixed mass through another moving mass.

FIG. 1, 2, and 3 depict, respectively, a side view, top and front view of the proposed vibratory machine with a working member receiving vibrations from the vibrator from the side of the stationary mass through another mass. FIG. 4, 5 and 6 depict a vibrating machine with a working member receiving vibrations from the vibrator directly from the side of another moving mass.

Cores / with coils 2, attached by means of brackets 3 to the support frame 4, act on their cores 5, attached by means of brackets 6, ton 7, and COLLARS S to the spring system 9.

The stiffness of the spring system 9, together with the weight of korea 5, the brackets 6, t g 7, and the squares 8 are selected close to the resonance setting. Therefore, under the influence of vibrator pulses, the spring system 9 will tend to develop oscillations

At the same time, the rigidity of the spring system // together with the rigidity of the spring-spring system 9, with the weight of the working frame 12 and the parts 73 of the tray 73 and htolniki 10 fastened to it, are selected in such a way that when their oscillations occur, the vibrations: calm down, i.e., they will tend to remain stationary relative to the support frame 4 and the cores / vibrators connected to it, regardless of the oscillations of the working ratios 12 and tray 13, despite the increase in their amplitudes with compliance with the condition of the dynamic equilibrium of the machine during its idle work.

However, as soon as worker cancer 12 and tray 13, due to the material being processed or transport of material, decreases the amplitudes of its oscillations, measles 5 with przhin-spring 9 will again tend to develop oscillations and cause increased oscillation of the working frame 72 and tray / 3 in accordance with the condition of the dynamic equilibrium of the machine when it is loaded.
