Consisting of a Blattfeäerb'indel " Agitator arm.

The inflation affects one from a leaf spring bundle "Existing agitator arm with one that encircles the peder blades tab.

Such "known" leaf spring-shaped agitator arms are used in devices for discharging wood chips, wood chips and the like from silos. They are arranged distributed on the circumference of rotors and run tangentially to the rotor axis, rotating in one plane or in several superposed planes. In discharge devices, the agitator arms convey chips from the silo to a further processing device. The leaf spring assemblies are heavily stressed to the extent that they can wind the rotor.

To hold the leaf spring bundle together, "tabs" are known

which enclose the individual peder leaves T "where the outer peder leaf of the leaf spring bundle is welded to the tab via a connecting plate. It has been found to be disadvantageous in this construction that the bending of the leaf spring bundle The connecting plate of the flap remains rigid and an inelastic sone is created on the peder blade, which causes the weld seams can be subjected to thrust loads from the connecting plate to the peder blade and can tear off,

These difficulties and disadvantages will be overcome after the innovation? that this consists of a number of peder leaves leaf spring bundles of various lengths between the two legs of a TJ-shaped bracket parallel to the web the flap is mounted and a rotatable sleeve delimiting the Pederbund is arranged between the flap legs which is connected to the end of the peder sheet of a shortened outer peder sheet of the leaf spring bundle B.

For more details and advantages of the innovation, refer to a drawing showing an exemplary embodiment, explained in more detail.

Pig. I shows the side view of a leaf spring bundle with tabs and

Pig, 2 shows the top view of Pig. I. The leaf spring-shaped working arm 1 consists, for example, of several

superimposed spring leaves 2 to 8, which in 9 are summarized and stored.

The tabs 9 are made from a U-shaped bracket with a web 11 and loops 12, 12a formed, the legs 12, 12a laterally encompassing the spring leaves 2 to 6 and 2 to 7, respectively rest on the web side with their broad side. Between dw A pin 13 delimiting the leaf spring bundle is attached to the loops and carries a sleeve 14 that can rotate on it.

For increased elasticity of the leaf spring bundle 1 in the event of bending loads, the spring leaves 7 and 8 are in length executed stepped, so that they are shorter than the individual springs of the leaf spring bundle 1. The approximately ^ over the entire length of the leaf spring bundle 1 reaching spring leaves 2 to 6 are at the end for conveying goods, e.g. wood chips, bent and designed as a scratch or scraper.

The tabs 9 are arranged on the leaf spring bundle 1 in such a way that the shorter spring leaves 7 and 8 with their spring leaf end 15 or 16 are welded to the rotatable sleeves 14 of the bracket 9, whereby the leaf springs 7 and 8 are movably held and can withstand high and continuous bending stress without the connection of the sleeve to the spring leaf enters, as is the case with the conventional rigid Fsder ^ Lasehenverbisdungen.

It is also achieved that when the springs are stressed on bend the bending line of the leaf spring bundle runs continuously and not through a rigid zone of the spring "leaf" is interrupted.
