DETAILED DESCRIPTION OF THE INVENTION

[0025] FIG. 1A shows a side view of the separator according to the invention. The separator consists of a frame I and the base II. The base II is mounted on shafts formed by eccentric tubes 2. These are shown very clearly in FIG. 28. In the eccentric tube 2 eccentric tube discs 201 are attached to or fixed on an inner shaft 202. Between eccentric disc 201 and eccentric tube 2 a bearing 203 is provided. In the shown embodiment four eccentric tubes altogether are provided (see FIG. 2B). Two eccentric tubes 2 are provided as a first pair of eccentric tubes 41 at the top end of the base I, seen in installation direction, and two other eccentric tubes 2 as a second pair of eccentric tubes 42 at the bottom end of the base I. Paddle holders 110, 120 are arranged at the eccentric tube 2. The base II is formed by 6 paddles 11, 12 in the shown embodiment. This configuration is by no means restricting, but shows only one possible embodiment of the separator according to the invention. As already mentioned above in the description it is possible to use two, three, six, eight, nine, or ten paddles 11, 12. The frame I is attached to or put up at a short elevation 8 and a long elevation 9 such that the base II, with respect to the installation surface, is arranged at an increasing angle, seen from left to right. Furthermore, the frame I is formed by a front frame 3 and frame sheet metals 4, 5. A sidewall 19 completes the frame on the side. At the elevations 8, 9 the frame I is defined by means of bolts 7 fixed on the side by discs 6. A not in detail described guide unit, at least consisting of a not in detail described rod, a roller holder 21 and a turn piece 20 is provided for a lateral and vertical guide of the eccentric tubes 2. It is arranged left and right, respectively (see section A-A in FIG. 1B) besides the eccentric tubes 2. The base II or the single paddles 11, 12 are connected via the paddle holders 110, 120 with the eccentric tubes 2. They are preferably formed by leaf spring elements 10, 40. For each paddle 11, 12 at least one paddle holder 110, 120 at each eccentric tube 2 is provided. A drive unit, consisting of a drive motor 1 and transmission elements completes the separator according to the invention. The drive motor 1 produces a rotary movement that is transmitted via the transmission elements to the eccentric tubes 2. As transmission elements toothed belt discs 18 and toothed belts 15, 16 are provided. Thus the rotary movement is transmitted synchronously to the eccentric tubes 2. The eccentric arrangement of the inner shaft 202 and provision of the eccentric tube discs 201 at the eccentric tube 2 generates an oscillating rotary movement of the paddles 11, 12. The consequence is the already described effect that an impulse is transmitted to the material to be separated leading to a separation of the single particles. Because of the covered arrangement of the inner shaft 202 and the eccentric discs 201 in the eccentric tube 2 dirt falling through cannot affect the bearing 203. Additionally, the eccentric tubes 2 are sealed by lids on the front side so that intrusion of dirt particles is almost impossible. Other reference numbers in the drawings refer to different machine elements that are of no relevance for the invention. These are nuts 23, 26, 31, 34, screws 24, 28, 29, 32, 35, 37, and discs 25, 27, 30, 33, 36. Flange bearings are referred to by 22, a taper sleeve by 14 or 17, and a distance plate by 13.
