Description

t

This invention relates to devices for volumetric dosing of bulk materials.

A dispenser for bulk materials is known, comprising a housing, a disk with dispensing sockets, a shut-off device, a control system and a agitator l |,

However, the known dispenser does not provide fast and accurate filling of the dispensing nests at the same time, since the vanes located at an angle to the dispensing nests. The corpus feria undercut a layer of powder gradually as the portion progresses toward the grating hole.

The closest in technical essence to the present invention is a device comprising a housing, inside of which there is a flow divider, made in the form of a cone of elastic material 2.

However, in the known device, the material is not uniformly supplied due to the curvature of the cone-forming under the weight of the material.

The purpose of the invention is to improve the uniformity of the feed material.

This goal is achieved by the fact that the cone is mounted on a spring

the frame, and the tops of the cone and the frame are rigidly connected to each other and mounted with the possibility of vertical movement along the guide, which is located inside the frame.

FIG. 1 shows the dispenser, a general view; FIG. 2 shows a section A-A of FIG. 1. FIG.

The metering hopper includes a housing 1,

0 in the lower part of which, on the periphery, there are dispensing slots 2 formed by the ring 3 and the radial partitions 4 attached to it, the divider made

5 in the form of a spring frame 5 covered with an elastic sheath 6, for example rubber, polyethylene, etc. Ring 3 is connected with a reciprocating mechanism

0 presses via rack and pinion & gearing 7. In the bottom of the case there is an outlet 8, above which is fixed a volume cutter 9 of a portion. With the drive of the reciprocating press mechanism, a feeder 10 is connected. The dissector base is rigidly connected with the guide 11, and the top is made with the possibility of vertical movement along the guide through the cone 12.

0 The device operates as follows. When dispensing, the material 1 is poured into the housing 1, which enters the dispensing slots 2. Under the weight of the material, the spring frame 5, covered by the shell b, is lowered and maximally increases the useful capacity of the bunker. At the same time, the material in the metering nests is under certain pressure. When the press is turned on, the reciprocating mechanism (not shown in the drawing) transfers ring 3 with the help of gear-pinion gearing. When each nest 2 approaches the outlet 8, the dose is separated by the splitter 9 and fed to the feeder 10. After emptying feeder, during the return stroke, the rack and pinion gearing 7 again moves the ring 3 to one slot and the dosing cycle repeats. As the hopper is emptied, the spring frame 5 raises the cone 12, increasing the powder pouring angle, and thus ensures an even flow

FIG. / powder without hanging on all dosing nests. Claims of the bulk material hopper containing a body inside which there is a flow divider made in the form of a cone of elastic material, characterized in that, in order to improve the uniformity of the material supply, the cone is mounted on a spring frame, and the tops of the cone and frame are rigid connected by the method and installed with the possibility of vertical movement along the guide, which is placed inside the frame.
