Embodiment Construction

[0037] Figure 1a It is a three-dimensional schematic diagram of a hammer head 1 according to an embodiment of the present invention. Wherein, the base body 2 has a through hole B, and the through hole B is used for connecting the hammer head 1 with the rotor and / or a rotating shaft (not shown in the figure) of a pulverizing device. The body 2 has a cutting attachment 3, the entire surface of which corresponds to the positive connection V is surrounded by the body 2, as shown. The cutting attachment 3 has cutting edges and / or cutting edges 31 , 31 ′. Such as Figure 1a In the embodiment shown, the cutting edge is, for example, welded-on hardened sheet metal. However, it is not restricted to this embodiment, but various variations are possible. The hammer head represented by an arrow is generally designated by component number 1 . Positive lock connection V at Figure 1b There are other more obvious signs. It is marked with an English letter V and is formed on the base 2...

Abstract

The invention relates to a hammer, in particular for comminuting devices, comprising a rotor and / or at least one shaft on which the hammer (1) can be fixed. Said hammer consists of a base body (2) provided with a through hole (B) which is provided to join the hammer (1) to the rotor and / or the shaft, and a cutting attachment (3) which can be detachably / rigidly connected to said base body (2) by at least one positive fit connection (V) and can be detachably / rigidly connected by at least one connection means (4) which exerts a force (P) which connects the cutting attachment (3) to the base body (2) by means of a positive fit connection.; The invention is characterized in that a force (P1) resulting from the force (P) guides the cutting attachment (3) into the base body (2) at an inclined angle (a) in relation to an axis (Y) of the hammer (1) and an axis of symmetry (A) by means of the connecting means (3) which is essentially parallel to the axis (Y).

Description

technical field [0001] The invention relates to a hammer head, in particular a hammer head for comminution plants having a rotor or at least one rotating shaft and which can be fastened thereto. Background technique [0002] Shredders are known which have at least one hammer mounted on a rotor and / or a shaft in the shredder for the purpose of shredding material in interaction with a supporting blade arranged in the shredder. However, the main disadvantage of the crushing equipment with hammerheads in maintenance and repair is that the knives and / or knife holders are very easy to wear, so users need to replace the knives or knife holders frequently, and the replacement of knives is quite time-consuming, causing the crushing equipment to be shut down for a period of time a long time. [0003] The previous German application DE G9415108.3 has disclosed in the prior art a well-known comminuting device, the cutting tools around it, especially the hammerheads provided, are of piv...
