Embodiment Construction

[0027] In the following, the present invention will be further described by using the following embodiments in conjunction with the accompanying drawings.

[0028] Such as Figure 1-4 As shown, it is the ditching machine cutter head of the present invention, which is fixed by a cutter head seat, and the cutter head includes: a cutter tip part 1, which is a quadrangular pyramid; an installation part 2, where the cutter tip The part 1 is fixedly connected to the cutter head seat, and the entry angle α formed by the axis of the cutter tip part 1 with respect to the normal line of the ground is an acute angle.

[0029] In order to further increase the effective cutting area of ​​the cutting edge formed by the edge on the blade, the apex and the edge of the quadrangular pyramid are rounded. Certainly, for realizing the purpose of the present invention, the size of the rounded corner of the edge of the knife tip 1 is not unique, and a preferred value is provided in this embodiment:...

Abstract

The invention provides a tool bit of a ditcher. The tool bit of the ditcher is fixed through a tool bit base. The tool bit of the ditcher comprises a tool nose portion and an installing portion, wherein the tool nose portion is a rectangular pyramid, the tool nose portion is fixedly connected to the tool bit base through the installing portion, and the installing portion enables the penetrating angle formed between the axis of the tool nose portion and the normal of the ground to be an acute angle. The tool bit of the ditcher is good in soil cutting effect and high in soil output efficiency and structural strength, and can be widely applied to ditching operation for burying cables.

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...
