Cutting machine with anti-winding cup

Abstract

The invention relates to a cutting machine with an anti-winding cup. The cutting machine is provided with an engine and other rotating driving parts and is connected to a rotating shaft of the rotating driving part through a connecting rod; and a bearing part of a rotating knife is arranged at the top end of the rotating shaft. The cutting machine is characterized in that the cup-like anti-winding cup consisting of a side wall with a set height and a bottom wall is fixed at the lower end of the periphery of the bearing part in an integral manner under a state of opening the side of an anti-rotating knife, wherein the side wall is in a slightly round shape from plane view, and the center of the bottom wall is provided with an opening of which the inner diameter is more than the outer diameter of the lower end of the periphery of the bearing part; and the anti-winding cup is fixed through a fixing means and is not protruded from a mounting surface of a bearing part supporting flange to the side of the rotating knife. According to the cutting machine with the anti-winding cup, disclosed by the invention, vegetation and the like can be prevented from being wound at the front end of the cutting machine, the burden of operators can be reduced, and cutting operation can be effectively carried out.

Description

technical field [0001] The present invention relates to a cutting machine with an anti-tangle cup used for cutting vines, trees, etc. Background technique [0002] Conventionally, a cutting machine used for cutting wood or the like is equipped with a motor as a rotary drive unit, and a rotary blade such as a blade saw mounted on a support flange of a bearing portion at the tip of a rotary shaft driven by the motor to rotate. Then, in the actual cutting operation, the cutting edge (blade) of the rotary knife is aligned with the roots of vegetation and the like to cut. In addition, this type of cutting machine is disclosed in, for example, the publication of Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2006-122016). [0003] However, when using this type of cutting machine, the grass cut by the blade of the rotary knife will be entangled on the bearing part of the cutting machine, etc., and the number of revolutions of the cutting machine may some...

Problems solved by technology

[0003] However, when using this type of cutting machine, the grass cut by the blade of the rotary knife will be entangled on the bearing part of the cutting machine, etc., and the number of revolutions of the cutting machine may sometimes be reduced. To prevent this kind of entanglement, the operator needs to Set the number of revolutions of the cutting machine in advance to more than the actual number of revolutions required, and work in this state

In addition, if the vines and the like are entangled with the cutting machine, etc., it is necessary to remove the vines and the like by increasing the number of rotations of the cutting machine, etc. If the vines and the like cannot be removed even if the number of rotations is increased, it is necessary to stop the cutting operation and remove them by hand. , therefore, during the cutting operation, the burden on the operator tends to increase, making it difficult to effectively perform the cutting operation
