Agitator for centrifugal spreader

The invention relates to an agitator for centrifugal spreader for applying mineral fertilizers * sand or the like., with a round, funnel-shaped container in which a Rührstal? © ä: shaft revolves with an upper thrust washer.

Agitators for centrifugal spreaders, with which different types of fertilizer mixed in the funnel and one. Centrifugal disc are to be fed, are available in different "execution * forms known. In its simplest form, the agitator consists of one that protrudes into the funnel and that has pins occupied stirring rod, which is eccentric on a drive pin protruding out of the gear into the funnel and is articulated and at the upper end a round thrust washer wearing. -The thrust washer is used to hit the Prevents pins against the wall of the conveyor. »These agitators have the disadvantage that they stick to particularly moist grit Rotate one point and create a cavity.

The invention is based on the object of an agitator for To create centrifugal spreader, the stirrer rod forcibly along the Triehterwand and thereby a wave movement executes. Another task is to design the agitator so that the funnel is exposed to vibrations,

the caking of the grit on the hopper wall and prevent bridging. In addition, the invention is based on the object of addressing the disadvantages of the prior art the technology to eliminate.

Based on the well-known agitators for centrifugal spreaders for spreading mineral fertilizers, sand or the like .., with a round, funnel-shaped container, in which a stirring rod shaft rotates with an upper thrust washer, the invention on which the d-he is based rotates The object is achieved in that the thrust washer is oval Owns floor plan.

In a practical embodiment of the invention Agitator, the oval thrust washer is also eccentric arranged on the stirrer shaft and provided with an imbalance.

The agitator designed according to the invention has the advantage that the stir bar shaft is in a randomly formed cavity performs a wave movement in the grit and jumps back and forth so intensely that the adjacent grit of is seized by the agitator blades and forced to slide, This means that the formation of bridges in the grit is as good as impossible.

Further details, features and advantages of the item of the invention emerge from the following description of the accompanying drawings, in which a preferred embodiment of the invention is shown. Point in the drawing

Fig. 5 the same stirring rod shaft with unbalance in plan view,

In the agitator shown, an agitator head (a) is bayonet-locked attached to a gear journal (b). on A joint piece (e) is mounted on a bolt (c). In the joint piece (e) a stirring rod (f) with the eccentricity (g) is pivotably mounted. Along the length of the stir bar (f) Various stirring paddles (h) are attached, which are in are arranged approximately on a helix. At the upper end of the stirring rod (f) there is a thrust washer (i), which with the eccentricity (k) is attached to the stir bar. An imbalance (l) increases the intensity when the agitator is running slowly the stirring effect.

Due to the double-jointed arrangement of the agitator on the gear journal (b), the agitator is able to '' attach itself to the wall- » of the funnel-shaped container and to roll on this wall. The stirring paddles (h) arranged on a helical line mix the components of the spreading material thoroughly by. It is not possible to rotate the stirring rod in a cavity because the oval thrust washer creates a wave movement and the imbalance causes vibrations.

All the new features mentioned in the description and shown in the drawing are essential to the invention, even to the extent that they are they are not expressly claimed in the following claims.
