Description

one

The invention relates to metering devices and can be used in industries where the material to be dosed requires pretreatment to break up lumps, arches and dispersion.

A known dispenser for cf-mate- rial materials, containing a feed chamber and balls located in it, and a driver for movement of the balls 1.

The closest to the technical essence of the proposed is a dispenser for bulk materials, containing a loading hopper, an intermediate chamber with working bodies and a driven disc, and a discharge chamber 2.

However, the performance of such a metering device is governed by the speed of rotation of the disk, for which they use direct current motors with an autonomous power supply, which are cumbersome, heavy, expensive and scarce, as electric drives.

The purpose of the invention is to simplify the regulation of the performance of the dispenser.

This goal is achieved by the fact that the intermediate chamber is made

a spherical shape with perforated holes in the lower part, and a dispersed surface and is installed with the possibility of changing the angle of inclination relative to its horizontal position, while the intermediate chamber is freely installed in the discharge chamber and is spring-loaded i.

The drawing shows the proposed dispenser, General view.

The dispenser contains a hopper 1, combined with intermediate caster 2, inside of which are located a disk 3 with a relief surface and working bodies - balls 4, perforated bottom 5 of chamber 2, holes with a diameter smaller than - working bodies 4, unloading chamber b, springs 7, the actuator 8 and the limiter 9 of the angle of rotation of the disk 3.

The dispenser works as follows.

Through the hopper 1, the material is fed and the electric drive 8 is turned on. At the same time, the disk 3 rotates and converts the working bodies 4 into chaotic motion.
