Embodiment Construction

[0042] On a milling head 30 (also called a milling wheel) of a dredger, one or more adapter cavities 11 are constructed on one of the blades 10 of the milling head. The milling head 30 has several blades 10 or arms which are fitted partly on a hub 41 at the top end of the milling head and partly on a ring 40 at the base of the milling head. The blades 10 are gathered at a hub 41 and the hub 41 is preferably configured with threads for assembling the milling head 30 on the dredger and for transmitting force from the dredger to the milling head 30 . Typically, a milling head 30 for a dredger consists of an even number of blades 10, where it can be seen that two different versions of the blades exist. Where two different blades are used, the two different blades have individually positioned adapter cavities 11 and thus also individually positioned knives 50 (also called teeth) so that the milling head 30 can be obtained with Appropriate configuration for processing. Several cut...

Description

technical field [0001] The present invention relates to milling heads and blades for dredging machines, and associated tool holders for blades of dredging machines. Furthermore, the invention relates to a cutter arrangement on a blade or milling head for a dredging machine. The invention further relates to a method of assembling a tool holder in a milling head for a dredging machine. Furthermore, the invention relates to a method of manufacturing a blade or a milling head for a dredging machine including an adapter cavity. Background technique [0002] Devices for dredging are used to displace, dig out or suck up material or sediment wholly or partly in a liquid such as water. One example of a device for dredging is a dredger. Different types of dredgers are designed for different applications and can include numerous assortment of different machining methods for displacing, dredging or sucking up material or sediment. For example, dredgers can be based on different type...
