rotary knife for cutting

Abstract

The invention relates to a rotary cutter for cutting. According to the rotary cutter, while a cutting edge is formed on the peripheral edge of a circular-plate-shaped substrate metal disk, a mounting hole for mounting onto a cutting machine is formed in the center of the substrate metal disk. An anti-inward-rolling part is integrally and fixedly mounted on the surface, which is mounted onto a mounting surface of the cutting machine, at one peripheral side of the mounting hole of the substrate metal disk, and the anti-inward-rolling part comprises a mounting part located at the peripheral side of the mounting hole, multiple vertical wall parts formed on the peripheral edge of the mounting part at certain intervals along the rotating direction of the substrate metal disk in a state of protruding by a certain size, and open parts being larger in area than the vertical wall parts and arranged between the vertical wall parts. By adopting the rotary cutter for cutting, grass, trees and the like are prevented from being rolled into the end part of the cutting machine, splashed soil and mud, cuttings and the like are prevented from adhering, the burden of operating personnel is lowered, the efficiency of cutting operation can be increased fully.

Description

technical field [0001] The present invention relates to a rotary blade for cutting that is mounted on a cutting machine and used when cutting grass, vines, small trees, etc. (hereinafter referred to as vegetation, etc.). Background technique [0002] Conventionally, as a rotary blade for cutting of a blade saw, for example, there is disclosed in Patent Document 1 (Japanese Laid-open Publication No. H06-24429). The rotary knife is on the outer periphery of the circular plate-shaped base metal disk, and the fixed installation parts and the knife chambers of a plurality of blades are alternately formed according to certain intervals, and the blades are respectively brazed at each fixed installation part of the blades. [0003] However, with this type of rotary knife, the grass, etc. cut by the blade will be involved in the support flange at the end of the cutter during the cutting operation, and sometimes the rotation speed of the cutter will be reduced. vines, etc.), the oper...

Problems solved by technology

[0005] However, this rotary knife with an anti-involvement cover prevents grass and trees from contacting the supporting flange through the flat side wall of the anti-involving cover. During operation, the splashed soil and mud generated by the rotation of the rotary knife, or the splashed vegetation and other chips generated by the cutting, will enter the inside of the anti-wrapping cover from the upper part of the opening, and it is easy to cause accumulation (adhesion). It is difficult to fully improve the efficiency of cutting work, such as the weight of the cutting machine end of the knife increases.
