Description
The present invention relates to a cutting machine, more particularly, to a cutting machine that supports a cutting blade and supports a rotary cover attached to a rotary shaft of a cutting machine by inserting a rotary cover to secure the rigidity of the portion to which the cutting blade is mounted, It is possible to increase the durability by preventing the mounting portions from being worn or damaged even if the rotary cover is removed or mounted, and the safety cover can be covered on the bracket for supporting the rotary shaft to cover the rotating body portion, Which can prevent safety accidents caused by the parts.
The present applicant has filed and filed a patent application for "easy-to-replace and safe cutter" as in the following patent document.
The patent document discloses that the protective cover attached to the rotary housing is rotatably supported by the bearing while increasing the radius of rotation of the cutting blade mounted on the rotary housing to increase the working radius of the cutting blade, The object of the present invention is to provide a safe and easy-to-use replacement cutter that can safely cut off a rotatable housing or an object that may cause danger such as a stump or a hemorrhage. .
In addition, the patent document can always receive a support with a predetermined elastic force when working on a workday, so that it is possible to prevent a safety accident caused by excessive rotation of the workday, and to prevent the workday from being hit by other components Another aim is to provide a safe and easy-to-use, ready-to-use cutter that can safely cut and prevent damage or noise from occurring.
In addition, the patent document discloses that when only the fastening bolt that rotatably supports the cutting blade is loosened, it can be directly mounted on the rotary shaft of the conventional cutter, and can be used conveniently and quickly, and can be easily replaced and used. .
However, this conventional cutter has the following problems.
(1) Including the rotating cover and the rotating plate, the rotating part that performs the mowing operation while being actually rotating is exposed to the outside, which may threaten the safety of the operator in the mowing operation.
(2) In other words, the operator performs the mowing while looking at the rotating cover and the rotating plate rotating with the cutting edge protruding outward. At this time, foreign objects such as stones hit the rotating body part during the work, There is a fear that a safety accident occurs due to a sudden rotation as the rotating body portion comes into contact with a tree or a rock.
(3) Due to the characteristics of the cutting machine, it is necessary to separate the cutting blade from the cutting machine due to dullness or breakage during the cutting operation, and then to reassemble or replace with a new cutting blade.
(4) At this time, the cutting blade is usually mounted on the rotary plate by a fastening method. In this fastening process, the rotary plate or the cutting blade often breaks due to improper fastening or tightening too tightly.
(5) In other words, the cutting blade is an important part that rotates and practically performs cutting work. In order to prevent safety accident while the cutting blade is released during the cutting operation, the cutting blade must be tightly fixed to the rotating plate.
(6) However, if the workpiece is tightened too strongly, the workpiece can not be rotated well and the workpiece can not be cut. If the workpiece is too strong, the rotation plate may be damaged. In addition, sometimes the holes for fastening or tightening the fastening screws are worn or damaged.
(7) In particular, such breakage or wear is frequently observed in a cutter using a rotating plate made of the same material as a synthetic resin.
The present invention is conceived in consideration of this point. By constructing the rotary cover and the rotary plate to be covered by the safety cover when the mowing operation is performed by the workers, the rotary parts are rotated, and stones or hard foreign objects are bumped, The present invention has been made to solve the above-mentioned problems in the prior art.
Particularly, in the present invention, the rotary plate is manufactured by an insert method, and the stiffness of the cutting edge and the mounting portion of the rotary cover to be mounted on the insert are increased, so that the rotary blade is frequently replaced or replaced by a wear or breakage Another object of the present invention is to provide a cutter that can prevent breakage of these mounting portions and increase durability even if they are reassembled.
In addition, the present invention has a configuration in which a triangular protruding portion is formed on the cutting edge, and the protruding portion is fitted on the seat formed on the rotary plate, so that the protruding portion is seated accurately at the assembly position. Another purpose is to provide a cutter that allows the cutaway to be assembled.
In order to achieve the above object, a cutting machine according to the present invention includes: a
Particularly, the
In this case, the polygonal shape is an equilateral triangle.
The
Lastly, the
The cutter according to the present invention has the following effects.
(1) When the mowing operation is carried out, the rotating cover and the rotary plate exposed to the outside are covered with a safety cover so that they can not be seen by the operator. Therefore, it is possible to prevent safety accidents can do.
(2) Since the safety cover is formed so as to surround the entire rotating cover, it is possible to prevent a safety accident that may occur due to sudden rotation of the rotating body portion due to the corner portion of the rotating body even when the corner portion is mowed .
(3) The rigidity of the rotating plate, which is frequently fastened and loosened by fastening means such as bolts, screws, etc., can be compensated for, thereby enhancing the durability of the cutter.
(4) Particularly, by reinforcing the rigidity of the connecting portion through the inserts and constituting the entire shape with the synthetic resin, it is possible to minimize rigidity and minimize the overall weight increase.
(5) At this time, since the rotary plate is extruded or injection molded by the insert method, it can be easily manufactured in a large quantity.
(6) In addition, since the cutting blade is provided with a flange so that it can be easily positioned after the replacement or repair, anyone can easily assemble or disassemble the cutting blade between the rotary cover and the rotary plate.
