Abstract

The present invention relates to a magic flying cutter, which is an improved design of a cutting machine magic cutter, and joints the body portion of the cutter and the member that combines the blade portion with a flowable member, so that a foreign object such as a protrusion and a frontal or deviated side impact during the mowing operation This is a complement to the blade being broken, bent, or twisted. If there is a side impact on the blade, the blade combined with the connecting joint moves up and down, and if the frontal collision leads to the blade, the blade rotates to the cutter body line area. It is to provide a functional flying mowing magic flying cutter that minimizes breakage of the cutter and the blade portion to extend the service life and ensure the maximum safety of the operator.

Description

Magic flying cutter {Magic flying cutter}

The present invention relates to a magic flying cutter that improves the shortcomings of the cutting machine magic cutter (20-2004-0022748), there are a number of cutters for the mowing device, such as straight, rolling, etc., farms, farms, orchards, or As a tool device for cutting weeds and uneven crops such as oxygen, gardens, and roadsides, when weeding in places where weeds and other crops are grown, we cannot find stones stuck in the ground or other hard foreign objects. When working, when the cutter blade which rotated at a high speed against such an object hits the front face or shifts | deviates, the cutter blade was broken or the distorted end which occurred very frequently has occurred. This phenomenon is because the straight cutter is rigidly fixed to the drive shaft which is rotated by the power of the mower power unit and the rolling cutter is rigidly coupled to the blade part and the main body part. Even if the impact angle collides with the front or only slightly shifted, the cutting edge of the cutter is twisted or bent, which causes difficulty in mowing due to the shaking phenomenon during rotation.

Magic flying cutter of the present invention is divided into the main body portion (Figs. 2, 3, 20); and the blade portion 30; and the connecting joint (Fig. 1, 40 or 7); It is constructed in combination. Magic flying cutter for mowing device of the present invention, when the cutter body is bound to the power transmission drive shaft of the mowing machine and the cutter attached to the drive shaft is rotated, the blade part 30 is horizontally unfolded by centrifugal force so that the mowing operation proceeds. If the blade part 30 collides with the ground or the protrusion during the operation, the connecting joint which binds the blade part flows and the blade part freely escapes upward and downward so that the blade part does not face the collision object. It is to prevent breakage and to prevent the impact shock from being transmitted to the worker. In other words, the blade 30 is rotated inside the line of the main body 20 during the frontal collision, and the blade is rotated up and down during the up, down, left, and right side collision, and the blade and the blade are damaged. It is to provide a magic flying cutter for mowing machines with excellent cutting force, which prevents accidents and extends the service life of the worker.

In the magic flying cutter for mowing machine, the cutter body portion made of an eight-shaped elliptic plate; (Figs. 2, 3, 20) and the rolling blade portion (Fig. 6); and the body portion 20 and the blade portion 30 are combined Connecting joint; made of a combination of (40 or 7).

The following describes in detail an embodiment performed with reference to the drawings. Figure 1 is a completed real picture of one embodiment, the main body 10 of the 20 body of Figure 2 composed of a certain size of eight-shaped elliptic plate and coupled to the power transmission drive shaft of the mowing machine is opened, the blade portion 30 and In consideration of the size of the connection joint 40, the blade 30 and the connection joint 40 to the outside of the peripheral portion 10 in consideration of the size (see Fig. 5) that the blade 30 is integrated in the inner diameter of the main body 20. 2 and 3 are drilled at intervals of 180 degrees, and the blade 100 is provided on the opposite curved surface of the coupling tool 60 such as the cutting surface of the blade 30.

 In addition, although not shown in the drawing, the coupling portion 60 of the main body 20 of the blade application blade 3 may be 120 degrees, and the blade application of the four blade blades may be punctured at intervals of 90 degrees to form the body portion (FIGS. 2 and 3). 3 is a configuration as shown in Fig. 2, but characterized in that a perforated portion 50 for reducing the weight of the body portion 20 is opened.

FIG. 4 is a view in which the blade 30 and the connection joint 40 are combined with the main body 20 of FIG. 3, and the connection joint 40 is supported on an eight-shaped curved surface to form a coupling hole of the blade 30. 4, 60-1) side is to act as a supporting jaw to prevent the flow further into the inside of the main body 20 and shows that the blade 30 is integrated seated in the inner diameter of the main body 20.

FIG. 5 is a real photograph of the blade portion 30 seated in a size that is integrated in the inner diameter of the main body portion 20 as described in FIG. 4.

6 is a semi-circle of a size that is integrated in the inner diameter of the main body 20 in the configuration of the blade 30 in various forms, the blade is composed of a circular multi-stage (1). It is a blade part 30 which consists of a wave shape (2), consists of a circular shape (3), or is formed in the shape of the saw blade (4), and the coupling hole 60-1 was perforated at one end.

FIG. 7 is a connecting joint 40, and 40 of FIG. 1 forms an opening by a zero-shaped annular chainring, and then, the blade 30 and the main body 20 are joined and welded to each other to assemble the chainring. One-touch type, such as tile, bolt nut type clip can be configured to be assembled in accordance with the purpose of the present invention, and the user's convenience was considered by simplifying and functionalizing the cutter and easy replacement of the blade (30). .

The magic flying cutter (FIGS. 1 and 4) is completed by combining the main body 20, the blade 30, and the connecting joint 40, which are the structures described above, in a mechanical path.

8 is a real example of an embodiment of the main body portion 20 structure of another embodiment shows that various implementations can be made without departing from the scope of the present invention.

Looking at the operation state of the magic flying cutter completed in the above configuration, in the state in which the completed cutter (Fig. 1) is fixed to the power transmission drive shaft of the mowing machine not shown in the drawing, when the mowing engine operates, the drive shaft rotates at high speed As the blade 30 is horizontally unfolded from the cutter body 20 by rotating centrifugal force, mowing is executed, and if there is a remaining grass or winding grass, it is removed by the auxiliary blade 100 of the body 20. . At this time, when the cutter blade portion 30 that has been rotated hits a hard object such as a foreign material, stone, and wood in front of the blade 30, the blade 30 rotates inside the cutter body 20 line (Fig. 5), and the side impact that is displaced is Blade 30 coupled with connection joint 40 flexibly flows up and down to reduce shock and then rotates into cutter body 20, or maintains normal level when colliding objects are removed. It is going to proceed. The magic flying cutter has the function of completely preventing the damage of the mowing machine or the blade 30, scattering small splashes, and impacts not directly transmitted to the worker when colliding with foreign substances, thereby protecting the safety of the worker. To provide a magic flying cutter.

 The Magic Flying Cutter of the present invention is capable of moving the blade and the joint joint up and down efficiently without facing the colliding body even when external impact is accidentally applied from the front or deviated side of the cutter during mowing. Since it is flying, evacuating or turning to the line area of the cutter body, it prevents damage to the mowing equipment by external shock during mowing operation, which extends the durability life of the cutter blade and improves work efficiency and guarantees safety to the user. to provide.
