Description

(54) BATCHER BULK MATERIALS

one

The invention relates to devices for metering bulk materials, such as feed and enzyme preparations, on livestock farms.

Known dispensers, comprising a housing, auger and discharge window 1.

Also known dispensers containing a hopper, a casing, a transporting body, the discharge window 2.

However, the known dispenser does not have sufficient accuracy and uniformity of dosing.

The aim of the invention is to increase the accuracy and uniformity of dosing.

To achieve this goal, in the bulk materials dispenser containing a hopper, a casing; transporting body, unloading window, transporting body is made combined and consists of a screw screw with a shaft and a belt screw, the inside diameter of which turns increases from the shaft diameter to the outside screw auger, with this, a damper installed with the possibility of synchronous and counter rotation with respect to the tape of the screw and made in the form of a cone, the angle at the apex of which

two times smaller than the angle between the generator and the base, and one of the imaging cones is parallel to the plane of the body, while the cone is provided with a tape, the winding of which is oriented opposite to the turns 5 of the screw and the pitch of which is twice the pitch of the auger tape.

FIG. 1 shows the proposed device, a general view; in fig. 2 - distribution of the dosed material in cross section 10 of the dispenser; in fig. 3 - distribution of material in the longitudinal section of the dispenser.

Dispenser bulk materials contains

bunker I, casing 2, transporting body

3 consisting of a screw auger with shaft

5 FOR, ZB tape shneke, damping

authority 4, discharge window 5.

The dispenser works as follows.

Feed is fed from the hopper 1 to the screw auger with the shaft 3 of the transporting body 3 of the dispenser. 20, which is transferred to the belt bash PZ with a damping device 4, in which the material flow is equalized. The belt auger BZ and the de-amping device 4 direct the feed to the discharge window 5. In the belt auger with a gradual reduction in the width of the tape of turns, a portion of feed passes from one turn to another, thereby equalizing the total flow as it progresses to unloading window. However, based on the conditions of the required performance and the particular physical and mechanical properties of a number of materials, when it is necessary to significantly increase the width of the tape, this type of working body does not provide the specified uniformity.

In order to obtain a uniformly dispensed mass in accordance with the requirements for different capacities, an additional damping device was introduced into the device, its device, which rotates in the opposite direction relative to the transport body 3, additionally levels the flow of materials in the cross section of the dispenser (Fig. 2). The specified flow uniformity is achieved by cutting vertices (Fig. 3) and filling the valleys of the material flow with the turns of the damper 4. As a result of the joint action of the tape screw and the damper, the flow in the cross section and longitudinal section of the metering device is equalized.

The proposed dosing unit ensures the leveling of the material flow and contributes to the improvement of dosing accuracy in a wide range of bulk materials with

different physical and mechanical properties, regardless of performance.
