Centrifugal spreader, especially for dusty fertilizers «

The innovation relates to a centrifugal spreader, especially for dusty fertilizers, which contains a storage container from which the material to be spread is fed to at least one screw conveyor working in a trough, from which it is transverse to the direction of travel beyond the width of the centrifugal spreader a spout is fed to a spreader, preferably a centrifugal disk · The essence of the innovation is once to create the possibility of feeding the material conveyed by the screw to the widely spaced spreading organs in such a way that that an even distribution of the goods on the ground is possible and, on the other hand, a trouble-free supply of the goods to ensure the scattering organs "

According to the innovation, the first-mentioned advantage is achieved by that the direction of rotation of the screw conveyor in relation to the direction of travel seen from the right in clockwise direction and that each outlet opening for the material to be spread is in the direction of travel seen the front half of the screw trough wall is arranged. This measure shifts the increase transfer point of the material on the spreader against the direction of rotation of the spreader backwards, so that the material is already at such a throwing angle each leaves the scattering organ that the spread fans generated by the spreading organs overlap exactly and thus an even distribution of the spreading material on the ground is guaranteed·

Certain post-corrections can still be made in that each outlet opening can be changed in terms of its size and position. This allows the point of application of the material on the
Scattering organ are changed.

Each spreader with the screw conveyor is respectively over
connected a gear, it has proven to be useful that each end of the screw trough at the exit point for the
The screw conveyor contains a special sealing element. This sealing element prevents a large amount of the litter material from being conveyed out of the conveying trough by the rotating shaft through the space between the shaft and its exit point.

However, since a complete seal of the conveyor trough can hardly be realized or only with a very large and therefore expensive effort, a free space is finally provided between each end of the screw trough and the adjacent gear housing according to the innovation. As a result of this measure, the grit conveyed out of the trough by the screw conveyor does not penetrate into the subsequent transmission, but can freely hit the ground
or fall on the spreading element located under the gearbox
and is then distributed by this on the ground *

The innovation identified in the claims for protection is explained in more detail in the following description with reference to the accompanying drawings. Show it:

Fig. 3 shows the right end of the trough without a screw conveyor in perspective view from behind.

The trough 1 is below or behind a not shown here Storage container attached and contains a screw conveyor 2 and at both ends a spreading element 3 · From one The screw conveyor 2 is driven from the power source via the chain 4, the chain wheel 5 and the shaft 6. Each end 7 of the trough is provided with a seal 9 at the exit point 8. On the shaft 6 is within the transmission housing 10, which for End 7 of the trough 1 has a distance, a bevel gear 11 is attached, which meshes with the bevel gear 11 *. The latter drives the shaft 12 from a centrifugal disk 13. standing spreading element 3 pending.

Above each spreading element 3 is in the direction of travel seen in the front half of the trough 1, an outlet l4 is provided. Before this outlet l4 is below the trough 1 with a Opening 15 provided adjusting slide l6 in the slide rails 17117 'slidably mounted while on this adjustment slide 16, in turn, a slide 19 is arranged displaceably in the slide rails 18, 18. By the slide 19 can Size of the opening that becomes free, by means of the adjustment slide l6 the position of the opening can be set.
