Cutting machine

Abstract

The invention relates to a cutting machine. The cutting machine is provided with a rotation drive portion of an engine and the like and a bearing portion, the bearing portion is connected with a rotary shaft of the rotation drive portion through a connecting rod, and a rotary cutter is arranged at the end of the connecting rod. An anti-winding part is integrally and fixedly arranged at the lower end of the outer circumferential face of a bearing cover plate of the bearing portion through a fixing means, the anti-winding part is provided with a hole, a mounting portion, a plurality of vertical wall portions and a plurality of open portions, the outer diameter of the hole is lager than that of the bearing portion, a ground plain formed by the mounting portion forms is approximately annular, the vertical wall portions and the peripheral edge of the mounting portion are integrally formed in a vertical state, the open portions are formed between the adjacent vertical wall portions, and the area of the open portions is larger than that of the vertical wall portions. The cutting machine aims to prevent grass, trees and the like from being wound in the end of the cutting machine, meanwhile, splashing soil, mud, cutting chips and the like are prevented from being accumulated (attached), the burdens of operation personnel are relieved, and cutting operation efficiency can be fully improved.

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.
