AI Technical Summary

Problems solved by technology

[0008] However, despite improvements to cutting wires from various studies previously done, there is still room for improvement in cutting wires
Specifically, previous efforts to improve the machinability of the wire (which is clearly the most important quality requirement required) are still insufficient

Embodiment Construction

[0032] figure 1 is an enlarged view showing a section of a cutting wire 2 for a brush cutter and trimmer, the view showing the cross-sectional structure of the cutting wire. In the case of the figure, the cross section of the cutting wire 2 is star-shaped, and the cross section of its central body 3 is circular, and four longitudinal cutting edges 4 are arranged in a cross on the outside or peripheral surface of the cutting wire 2 .

[0033] In this case, on each longitudinal cutting edge 4 of the cutting wire 2, along the length direction of the cutting edge 4, sequential teeth 5 with regular height and shape and arc-shaped concave configurations are formed. . Thus, the position of the teeth 5 made on each cutting edge 4 can be designed to correspond to the same teeth 5 made on the other cutting edge 4 . Normally, the cutting wire 2 has good cutting performance, and all its cutting edges 4 are in the form of "sawtooth".

Abstract

The invention relates to a cutting wire (2) which is designed to trim or cut vegetation and which can be used on rotating head devices, such as brush cutters and edge trimmers. The external surface ofthe cutting wire is provided with tooth-type (5) or similar formations along the length of said wire (2). In the case of a wire having one or more longitudinal cutting edges (4), said tooth-type formations (5) are disposed on the cutting edge(s) along the length of each edge (4). In this way, the sharpness of the wire (2) is improved.

Description

technical field [0001] The present invention relates to cutting wires for pruning and cutting vegetation (shrubs or thatch), which can be used on agricultural mechanized equipment with a rotating working head, such equipment is commonly known as bush cutters and trimmers machine. Background technique [0002] This type of agricultural mechanization equipment is generally equipped with a heat engine or an electric motor, which drives a rotating head with one or more cutting wires installed on it to make it rotate at a high speed, the speed of which is about 300rpm to 12000rpm between. During the high-speed rotation of the rotary head, one or more cutting wires are moved radially outwards by centrifugal force to cover a circular area in which the wires cut the vegetation they encounter . [0003] Cutting wires currently produced and sold exclusively for this purpose are smooth-looking monofilaments, usually made of synthetic materials such as polyamide, which in the simples...
