Definitions
- the invention relates to a flail, in particular for crushing devices with a rotor or at least one shaft, on or on which the flail is fastened.
- Crushing devices which are equipped with at least one mallet, which are arranged on a rotor or on a rotating shaft in the comminution device and which cooperate for comminuting the material to be comminuted with a counter-blade arranged in the device, are known.
- a problem in the maintenance of equipped with flail shredders is usually that the blades or the blade carrier wear very quickly and thereby at least the blades or the blade carrier must be changed at regular intervals.
- the change of the blades is a time-consuming affair, which leads to prolonged downtime of the crushing device. It is now known to arrange knives rotatably on knife carriers in order to achieve a certain extension of the running time of the machine. It is also known to change the knives together with the cutter head or cutter heads.
- the DE 92 17 598 U1 relates to a grinding disc for a crushing roller of a crushing device, with a base body and with at least one of the main body circumferentially projecting fang.
- the DE 20 2005 009 859 U1 relates to a knife carrier for crushing devices.
- the DE 20 2006 007 055 U1 relates to a flail for a crushing device with a rotor on which the flail is attachable.
- the DE 20 2006 019 687 U1 relates to a flail assembly for crushing materials.
- the US 6,364,227 B1 relates to a shredding device and a means for mounting around a rotor.
- a compact unit is formed, which is characterized in that, in particular, the connection between lower body and cutting head is considerably improved compared to the solutions known in the prior art.
- the connection is in fact concealed or hidden in a compact structural unit of a bracket and is therefore no longer exposed to wear.
- the entire flail body is thus protected in the connection area from wear and in the case of wear of the blades on the cutting head easy replacement of the cutting head is now given.
- the hidden, located in the interior of the lower body connection between the lower body and cutting head also ensures a very secure connection, as a readjustment and centering of a new blade head on the lower body is no longer required due to the positive connection here.
- the measure according to the invention of forming the bracket in the form of a lower body with a cutting head and the connection according to the invention, namely such that a connection projection provided on the cutting head engages positively in a recess arranged in the interior of the lower body eliminates all problems with regard to wear known in the prior art on the lower body or knife carrier with respect to the connection of these two components.
- the invention is characterized in that lower body and cutting head form a structural, compact unit of a bowl in the connected state.
- this structural or compact unit of a bowl is advantageous because now the attack surfaces for the wear concentrate essentially on the outer parts of the cutting head and the lower body is substantially less affected by wear or remains free. It is given by the fact that the change cycle of the rotor or the shaft in the crushing device can be considerably extended. This achieves a higher production time of the comminution device and the service life due to maintenance work is reduced.
- connection approach is positive, self-centering and self-locking or self-locking engages in the recess. Due to the configuration of the connection approach and the recess not only a simple positive engagement is given, but it is achieved that the cutting head, next to a secure connection, centered at the same time when inserting and then locked itself or secures itself.

- the flail according to the invention now uses the securing means as an additional safeguard, which increases the safety of the crushing device as a whole.
- connection approach and the recess have a mutually corresponding shape and are formed self-holding.
- This solution offers, in addition to the already described self-centering and self-locking effect, a further increase in security.
- the entanglement can be relatively easily solved, for example, in case of repair by a light blow against the fuse relationship or Verhakungscardi (in the cutting direction).
- the recess is enclosed on four sides and has in particular lateral guide webs.
- These lateral guide webs offer a further advantageous effect, namely such that now actually the entire connecting means is concealed in the lower body and at the same time the cutting head is guided laterally during insertion into the lower body with its connecting means and thereby very safely brought into the desired position, without having to re-check it here. Even if a not 100% insertion, due to appropriate lighting conditions in case of repair does not seem possible. It is now easily possible, without visual recognition, due to the lateral guidance in cooperation with the recess and the corresponding, form-fitting configuration of the connection, to use the cutting head safely in the recess and to fix.
