The patent specification differs from the patent specification

The invention relates to a drive for processing machines, e.g. B. for dewatering, compacting, Sieving, classifying, etc., as an addition to patent 1239920.

The object, the improvement of which is the aim of the invention, is a drive for processing machines, for example for dewatering, compacting, sieving, classifying etc .; Consisting of a pulse generator, e.g. an electromagnet operated with alternating current, an oscillating armature arranged in its magnetic field and a transmitter that is pushed or moved by this armature and that acts on the processing machine or is connected to it, a lever clamped on one side being supported by an armature attached to it is excitable to vibrations at the free end in several degrees of freedom, furthermore the acting as a catalyst free arm at the free end of the vibrations to be exposed part of the processing machine is mainly more or less sagging _so forming fabric carries and assigned a fixed or spring-loaded and / or adjustable stop the armature .

The invention is based on the particular object of making the above-described subject more economical to design than before.

The problem posed is essentially achieved in that a two-armed pivotable lever is used as a lever and elastically mounted lever is provided, wherein. preferably for the elastic mounting of the lever an eye of the lever and a rubber sleeve spring held on the lever axis is used.

An advantageous and inventive; Design of a detail is characterized in that at The above-described object of the lever is designed as an angle lever, preferably its The load arm runs approximately vertically and its power arm ■ is directed approximately vertically downwards from the lever axis is.

. For this purpose, a further preferred and inventive training is characterized in that the above-described The subject of the pulse generator engages the side of the power arm facing the free end of the load arm.

In this way, you get a drive that is extremely robust and durable. Furthermore, thereby smaller dimensions can be achieved without the advantages of the already proposed drive be diminished.

A preferred and inventive development of the above-described subject further consists in that the drive for processing machines connected to the load
z. B. for dewatering, compacting, sieving,
Classifying, etc.

Edge part opposite edge part of a sagging screen fabric surface or the like held resiliently is.

• For this purpose, a preferred and inventive embodiment is characterized in that the above-described Object as a holder for the edge part opposite the edge part connected to the Lastann -Rand part of a sieve fabric a leaf spring or the like clamped on one side is provided.

Furthermore, a preferred and 'inventive embodiment of the above' subject matter characterized in that the edge parts of the sagging ones, which are expediently reinforced by edge strips The screen mesh surface is connected to the screen mesh holders at approximately right angles to the longitudinal extension of the screen mesh holders are.

These measures give the screen fabric surface or the like further, the efficiency of the drive increasing vibrational superimpositions.

The drawing shows an embodiment of the subject matter of the invention, namely a screening machine on average.

Here, two spars 1 carried by a frame (not shown) with a funnel 2 are in front.

Claims (7)

seen, wherein the funnel for the sieve passage can also be designed as a trough. A bracket bearing 3 for an angle lever 4, which is elastically supported by means of a rubber sleeve spring 5, is arranged on the left side rail 1. An electromagnet 6 acts as a pulse generator on the force arm Aa of the angle lever. To achieve high-frequency harmonics, the electromagnet 6 is assigned a stationary, mounted, adjustable stop 7. leaf spring 9 carried by the right spar 1 is held. Both edge parts are bordered with strips 10. The leaf spring 9 also advertises a superposition of further harmonics. Under certain circumstances it could be particularly advantageous for the elastic mounting of the angle lever to provide a rubber torsion thrust spring. This torsional thrust spring, like a rubber sleeve spring, thanks to its compressibility, will allow the return stroke of the electromagnet to lead the return stroke of the angle lever, so that harmonics are generated on the screen fabric surface. In addition, the restoring force of a rubber torsion thrust spring is out of phase with the restoring work of the lever, based on a conventional swivel joint with play, so that a further superimposition of harmonics takes place, which leads to a further increase in efficiency. It goes without saying that the suspension of the screen fabric shown on the left could also be arranged on both sides of the screen fabric. A leaf spring can be interposed between the free end of the load arm Ab and the strips 10, similar to the illustration on the right. ■ _ · ■ f patent claims: 40 45 1.
