PATENT OFFICE. \%

The subject of the present invention is a device for cleaning grain or separation of bodies of different specific gravity. The same thing consists in that the lighter substances, such as bran, etc., by virtue of a rotating stream of water on the Surface of the latter, the somewhat heavier grains of one weak water flow, while the heavy substances, such as stones, etc., by a be separated from a sharp stream of water and placed in a separate container.

The advantages achieved by the new arrangement over older constructions are According to the inventor, the following:

The apparatus has no sensitive parts which are subject to wear and tear or in need of repair. When cleaning, the grain only remains for a very short time Time in contact with the water. The whole handling is done very quickly, after which the grain is finally freed from moisture in a drying device. It the softest grains can be used without the use of stones, Lime and the like can be cleaned without causing a major loss of grain, since the latter cannot lower itself again.

The accompanying drawing shows the new device, namely is

Fig. Ι a section along the line 1-2, Fig. 3, FIG. 2 shows a section along the line 3-4, FIG. 3, FIG. 3 shows a top view of FIG. 1.

The new device consists of a disk a, which is arranged on a container a ¹ and is provided on the outside with an edge a ² . Above the disk is a tube b, which with its slightly bent end dips into the container a ¹ and is attached to the arm c of the machine. The tube b is formed at the end into a truncated cone d , in which the axis e , on which the disk α sits, has its bearing. In addition, the axis e carries a conical disk f at its upper end.

The arm c of the frame carries a tube g in the middle, which can be more or less closed by means of a slide g ^l. Another tube h is movable up and down on the tube g and is carried by a lever h ¹ to which a screw bolt h ^{2 is} articulated so that the tube h is supported by the screw. h ^s can be set in any way.

The edge α ^{2 of} the disk α lies in a channel i, the lower surface of which runs in the form of a screw and opens into a drain connection i ^1. At one point the channel is interrupted to a certain extent by a cavity k , the purpose of which will be explained below.

Radial is directed to the disk a a doctor blade / in the vicinity of the area k and two tubes m and m *, the ends of which are bent horizontally, in such a manner, the opening DAF the former m against the center of the disk A, the latter of m ^{1 is directed} in the opposite sense (Fig. 2 and 3).

Finally, the axis e carries a bevel gear ji at its lower end, which meshes with a bevel gear n ¹ . The latter sits on the shaft o, the end of which with a pulley j? is provided. The operation of the device is as follows. The pulley jp, which is driven by any transmission shaft, moves the shaft ο and transmits the movement by means of the wheels n ^l and η to the axis e, the pulley α and the conical pulley f. The water enters through the pipe b , fills the container a ¹ and penetrates through the gap provided between the disc α and the cone d. The same then spreads out in a very thin layer on the disk α and arrives thereupon, ^{stepping over the edge a 2} , to the channel i. The cereal itself is added through the pipe g ; After the slide g ^{l is} opened, the latter falls onto the conical disk f and now spreads completely evenly on the surface of the cone d. As already mentioned, läfst movable tube h precise control of the outlet quantity of grain to. A stop b ¹ , which is attached to the tube b , is intended to prevent the grain from settling on the latter respectively. spreads in the direction of the pipes mm ^1. The grain is now distributed on the plate α and is driven through the water in such a way that the lighter masses, such as bran, etc., are carried along over the edge α ² to the channel i , whereupon they are again freed from any moisture in a drying container . The somewhat heavier grain and the solid bodies remain on the plate α , which now leads them towards a first stream of water coming from the pipe in . This flow takes place under comparatively weak pressure and has the purpose of ^{lifting the grain over the edge <2 2} and also of conveying it to canal i . A second, sharper flow of water flows through the pipe m ^{1, which} holds the heavy bodies, such as stones etc., and conveys them over the edge α ' ² into space k , from where they then fall into a special container. The purpose of the doctor blade Z is to always hold back the stones which are located on the disk α , so that they are always in the area of the water flow from the pipe m ¹ . Pa τ E N τ - A ν s ρ R υ c H: Device for cleaning grain or separating bodies of different specific gravity, characterized by a rotating disc (a), over the edge (a ¹ ) of which the lightest substances, such as bran, etc., are first washed over by a stream of water overflowing it from the center while a first jet of water emitted from a pipe (m) lifts the grain itself over the edge and the heaviest substances are guided by a sharp stream of water from a second pipe (m ^l ) over the edge of the pane to a container (k) , a scraper (I) always keeps the heavy materials in the area of the water jets emerging from the two pipes (m and m ^l ).
