Abstract

The invention relates to vibratory conveying devices, and b. used in mechanical engineering, chemical and other industries of the industry; I transport piece and bulk chemically harmful, dusty and their gas. The purpose of the invention is to increase productivity. The vibrating conveyor includes a tubular working body (PO) 1 located inside the tubular reactive element 2 mounted on a fixed base on the shock absorbers. The reactive element 2 and PO 1 are interconnected by elastic elements mounted on the top center and bottom along the edges of the PO 1 at the same distance from its longitudinal axis. Each elastic element is made in the form of two spaced lattice springs 3 and 4. Springs 3, 4 are attached in the middle to the terminal clamps 5 and 6 in the lower part of the conveyor. In the upper part of the conveyor they are attached to the brackets 7 and 8. The ends of the springs 3 and 4 are interconnected in pairs by shoes. Electromagnetic vibration exciters of longitudinal vibrations are installed on clips 6, and their core - on clamps 5. Electromagnetic vibration exciter of normal vibrations 13 is placed in the middle of the conveyor below the reactive element 2, and its measles on PO 1.

The invention relates to a lifting and transport equipment, namely, vibratory conveying devices, and can be used in mechanical engineering, chemical and other industries to transport piece and bulk, chemically harmful, dusty and gaseous materials.

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

FIG. 1 shows a vibrating conveyor, a longitudinal section; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. one.

The vibrating conveyor consists of coaxially arranged pipes 1 and 2. The inner pipe 1 is a transporting organ, and the outer 2 is a reactive element.

Pa, a barrel body and a reactive element are interconnected by four pairs of elastic lattice springs 3 and 4 attached in the middle to the terminal clamps 5 of the working body and the terminal clamps 6 of the reactive element in the lower part of the conveyor, in the upper middle part of the conveyor spring attached to the bracket 7 working organ and arms 8 of the reactive element. The ends of the lattice springs are interconnected in pairs by the shoes 9 and 10. The electromagnetic longitudinal vibration exciters 11 are installed on the terminal 6 of the reactive element, and the measles 12 longitudinal vibration exciters on the terminal 5 of the working element. Electromagnetic vibration exciter of normal vibrations 13 is placed in the middle of the conveyor, on the bottom of the reactive element, and measles 14 vibrator of normal vibrations on the working body. Through the shock absorbers 15 installed under the shoes 10, the conveyor is supported on a fixed base. The center of mass and the center of rigidity of the conveyor are located below the longitudinal axis and are aligned with each other.

Vibrating conveyor works as follows.

When electromagnetic vibration exciters of longitudinal and normal oscillations are switched on with a phase shift between them, the working body and the reactive element oscillate along an elliptical trajectory, ensuring the movement of loads in a continuous or tear-off mode. When the phase shift of the oscillations is changed by 180 °, the movement of the weights is reversed.

Making stiffeners of lattice springs attached to the working body and the reactive element, inversely proportional to the masses in the longitudinal and normal directions, fixed at the ends through the supporting shoes, provides full vibration isolation of the conveyor. Installation of elastic elements from the top center and bottom along the edges of the working body on

5 the same distance from its longitudinal axis and the alignment of the center of mass with the center of rigidity of the elastic system with elliptical oscillations of the working body, eliminates the angular parasitic oscillations and

Q to increase the speed of transportation, which increases the performance of the vibrating conveyor as a whole.
