SU1502437A1 - Vibrating conveyer - Google Patents

Abstract

The invention relates to a vibration technique and can be used to move loads in various sectors of a national economy. The goal is to increase productivity. The vibrating conveyor contains a load-carrying body made in the form of a flexible tape (L) 1 of an inextensible material associated with drives (P) 2, 3, 4 and 5 of vertical reciprocating motion. On base 6, struts (C) 8 are mounted on shock absorbers 7. Between C 8, L 1 is bent in the form of a sine wave and fixed to them by means of vertical guides. The connection between P 2,3,4 and 5 and L 1 is carried out by means of hinges 10. P 2,3,4 and 5 are located from each other at a distance equal to γτ / ϕ, where γ is the phase angle of a sinusoidal wave between hinges 10

Τ is the distance equal to half the length of the sine wave. When oscillations are excited in P 2, 3, 4 and 5 with a sinusoidal law of motion in L 1, a traveling wave is formed, moving from left to right. The material located on L1, rolling down the wave, moves in the same direction. The productivity of the conveyor is increased due to the absence of distortion of the traveling wave. 1 hp f-ly, 3 ill.

The purpose of the invention is to increase the productivity of the conveyor.

FIG. 1 shows a structural diagram of a vibrating conveyor; in fig. 2 - conveyor, transverse times-10 ez; in fig. 3 is a graph of the movement of reciprocating motion.

The vibrating conveyor contains a load-carrying body, filled in 15 kind of flexible tape 1 of non-extensible material, associated with drives 2-5 of vertical reciprocating motion. On a stationary base 6, racks 8 are mounted on the shock absorbers 7, on which, by means of the vertical guides 9, a flexible tape 1 is fixed, curved by a sinusoidal wave.

Drives 2-5 of vertical return-25 HC-translational motion are connected to flexible tape 1 through shashirs 10

and are located at a distance jA tT from each other, where the phase angle of the sinusoidal wave of the flexible tape at the points of attachment of the drives 2-5 to it; T is a distance equal to half the sine wavelength.

In order to reduce sticking 35 of the material on the flexible tape, as is the case when wet moist materials are being transported, a vibrator 11 is fixed on the uprights 8, the lines of action of which are disturbed by the force of the load carrying organ.

Vibrating conveyor works as follows

where f is the oscillation frequency of the drives; g is the distance equal to half the length of the sine wave. In this case, the material on the tape, rolling down the wave, moves in the same direction.

At time t ((Fig. 3), the flexible tape 1 has the shape shown in Fig. 1. The length L of the flexible tape 1 in order to ensure the specified length, which can be calculated from the following considerations.

The displacement of the hinge 10 and, consequently, the point of the flexible tape 1 to which it is attached is determined by the equation
