Throwing device with throwing disc

It is known to arrange a metering and control device under a container in order to pass through the inlet openings the spreading disc set in rotation underneath with the material to be spread, e.g. artificial fertilizer, sand, etc.

to be sent.,

There are angle irons on a round or polygonal disc attached approximately radially as blades, which can also be adjusted.

The material to be spread has none on the leg of the angle iron that is perpendicular to the disc adequate guidance and becomes quite uncontrolled as a result thrown out.

There are also known throwing discs in which blades are welded to a disc, the blades themselves are designed differently, e.g. with a convex backward curvature, etc. Cast or forged piece formed.

The innovation creates a spreading disc that is easier to manufacture, lighter in weight and in evenly spread over a very large litter field.

In the case of the centrifugal device with a turn offsetting throwing disc, di & by one standing above it Container is supplied with the material to be scattered via a metering device, with the spreader vanes lie outside the inlet opening in the metering device, an advantageous production and distribution is achieved, if according to the innovation of the throwing wing as an edible part so is designed so that a throwing disc is formed when joining

RA, 587 243 * 9/11/63 ^

Another characteristic of "hiring" is that the The underside of the spreader blade looks conically tapered outwards and the Iragrinne for the grit is roughly U-shaped and the opposite edge is angled to the underside

In the case of the clay target according to the invention, the Material is guided in the chute until it leaves the spreading disc and it gets through the smooth ! "laugh after there was no joint between the pane and ! There is a wing, no impulses to jump and thus to uncontrolled knocking off

In order to increase the width of the spreading ring over which the material is to be spread, the Innovation of the circle for the diameter of the I-carrying channel for the individual throwing wings "varies" or the inclination to the horizontal is designed differently.

Further advantageous features of the innovation are the claims and the description below and to be taken from the drawing.

In the drawing shows:

Pig. 1 D _r oversight of the clay target with three Pig throwing vanes. 2 Side view of the Pig clay target. 3 shows a section along the line AB in Pig. 1.

The spreading disc is set in rotation by a gear 5 and fed with the material to be spread through a container β above it with a metering device 7 The metering device has at least one opening 8, the diameter d of which is smaller than the diameter of the plane surface a.

The throwing disc consists, for example, of the throwing wings 4, 4 '> 4 ^l * which, when put together, represent a disc with pluckers.

The wing is built by the Sangentenkreis e a straight line or curvature runs to the outer circle b, which is at the same time the rear side 2 of the lurffluge 4 and extends from the outer circle b to the plane area circle a as a groove 2, 2 '. The! Dangentenkreis can do it be centric or eccentric / target means 0, / for

D _e r ^ urfflügel extends in plan view towards the outside conical undiist the diameter b at its narrowest.

The front side 1 of the spreader blade 4 is approximately at right angles to the underside 3 and also runs conically to the outside, where the smallest height is at the outer diameter b.

The distance of the upper U-leg 2 ^{1 of} the support channel to the underside 3, which at the same time forms the lower U-leg, is equal to or smaller at the diameter b than at the flat surface circle a and the rear side 2, which represents the transition, is arcuate. The vanes 4, 4 *> 4 "can be inclined to each other and to the horizontal at an angle upwards or downwards.
