Description

technical field

[0001] The invention relates to a ditching machine cutter head, in particular to a ditching machine cutter head used for cable laying. Background technique

[0002] At present, trenchers are mainly divided into chain type, disc type and helical milling cutter type. Wherein, when laying cables, what usually use is a disc type trencher and a chain type trencher. The chain type trencher is prone to chain breakage when the speed is too high, and its reliability is low. The disc trencher is more stable than the chain trencher. The ditching cutter disc disclosed in Chinese patent document CN101507384B includes an annular knife seat and at least one set of ditching knives. The knife seat is evenly arranged, and a plurality of triangular grooves are arranged on the ditching knife surface. The above-mentioned ditching machine cutter head, the ditching knife is set in the shape of a hook, in order to reduce the actual contact area between the knife surface and the s...
