Description

FIELD OF THE INVENTION The invention relates to devices for the metered release of low-flowing materials from hoppers in the metallurgical, chemical industry, construction industry, as well as in agriculture.

A hopper for the metered delivery of low-flowing materials is known, including a fixed housing and installed in its lower part from the outlet side, with a perimeter gap, a movable assembly, an eccentric drive and a connecting rod. The disadvantage of this device is the presence of two vibratory drives, which reduces the reliability of operation and does not ensure the quality of dosing, since synchronization of the operation of two drives is necessary - the vibratory conduit of the funnel and the vibratory tray.

The purpose of the invention is to increase reliability.

This goal is achieved by the fact that in the hopper, which includes a fixed housing and installed in its lower part from the outlet side, with a clearance around the perimeter, a movable assembly, an eccentric drive and a connecting rod, the housing is provided with a false wall, one of the walls of the housing is inclined, the false wall elastically fixed to the inclined wall of the housing, the movable assembly is made in the form of a funnel with lateral outlet, the funnel is connected to the housing by a hinge, the eccentric drive is mounted on the inclined wall of the housing with the possibility of direct contact with the false wall, connected by a connecting rod to the funnel, and the drive is made with

the ability to communicate oscillations to the false wall and funnel in antiphase.

The drawing shows the proposed hopper, a vertical section.

The hopper contains a fixed housing 1, having an inclined wall 2 and a false wall 3 mounted above it, elastically mounted on the inclined wall of the housing. A movable unit made in the form of a funnel 4 with a lateral side is installed in the lower part of the housing from the outlet opening with a perimeter gap an outlet connected to the housing via a hinge 5. An eccentric drive b is mounted on the inclined wall 2 and mounted with the possibility of direct contact with the false wall 3. The drive 6 is connected to the funnel 2 by means of a connecting rod 7. The actuator 6 is configured to communicate oscillations to the funnel and the false wall in counter-phase. The false wall 3 is installed in the housing using flat springs .8. and is protected from falling under it of bulk material with a fixed visor 9.

The hopper operates as follows.

When the eccentric drive is switched on, antiphase vibrations are reported to the false wall 3 (and funnel 4 (via the connecting rod 7). The free-flowing material hanging during the movement of the false wall 3 constantly loses support and moves down to the outlet due to vibration and engraved forces. hopper 1 into the funnel 4 low-flowing material is shifted towards the outlet due to its rotational vibrations around the axis of the hinge 5.

Since the vibrations of the false wall and the funnel are carried out from one drive, the shear rate of the poor-flowing material along the false wall and in the funnel is synchronized.

Placing the longitudinal axis of the connecting rod perpendicular to the swing radius of the funnel 4 eliminates the radial loads from the drive b to the hinge 3, which significantly increases the reliability of the device as a whole.
