Cutting Machine

Abstract

The present invention relates to a cutting machine, which is equipped with a rotary drive part such as an engine, and a rotary shaft of the rotary drive part is connected by a connecting rod, and a bearing part of a rotary knife is installed at the end of the connecting rod. At the lower end of the outer peripheral surface of the bearing cover plate at the part, the anti-involvement part is integrally fixed and installed by means of fixing means. The anti-involvement part has a hole with a larger outer diameter than the outer diameter of the bearing part, forming a plan view A nearly annular mounting part, and a plurality of vertical wall parts which are integrally formed in an upright state on the outer peripheral edge of the mounting part, and a plurality of vertical wall parts which are formed between adjacent vertical wall parts and have a larger area than the vertical wall parts. Opening site. Its purpose is to provide a cutting machine that prevents vegetation, etc. from being involved in the end of the cutting machine, and also prevents the accumulation (attachment) of splashed soil, mud, chips, etc., reduces the burden on operators, and can fully improve the efficiency of cutting operations.

Description

technical field [0001] The invention relates to a cutting machine with an anti-entanglement cup used for cutting vines or trees (hereinafter referred to as vegetation, etc.) to prevent the cut vegetation from being involved. Background technique [0002] Originally, a cutting machine used for cutting wood and the like is disclosed in, for example, Patent Document 1 (UKK-06-72319). This cutting machine has a motor as a rotary drive part, and a rotary blade such as a blade saw mounted on a support flange of a bearing part at the end of a rotary shaft rotated by the drive of the motor. And, in the actual cutting operation, cut by aiming at the roots of vegetation etc. by the blade (blade) of rotary knife. [0003] However, in such a cutting machine, the cut vegetation is involved in the receiving bearing portion at the end of the cutting machine during the cutting operation, which may reduce the rotational speed of the cutting machine or stop the rotation of the cutting machin...

Problems solved by technology

[0005] However, on the cutting machine with this anti-involvement cup, the flat side wall of the anti-involvement cup prevents grass and trees from adhering to the bearing part. The splashed soil and mud generated by the rotation of the machine, or the splashed vegetation caused by cutting, will enter the interior from the upper part of the opening of the anti-entanglement cup, which is easy to cause accumulation (adhesion). The cutter end with a rotary knife is installed It is difficult to fully improve the efficiency of cutting operations, such as the weight of the part will increase, and it will be troublesome to remove accumulated soil and mud.
