Rotary blade supporter for mowing machine {SADDLE FOR POTABLE CUTTER}

The present invention is a mowing machine that can be attached to the cradle attached to the wheel to maintain the rotary blade to a certain height from the ground in order to improve the work efficiency by mounting the mowing blade to the holder instead of holding the rotary blade of the mower It is about blade holder.

In general, mowing machines are used in various ways such as quickly cutting weeds when farming farms, mowing lawns, or weeding oxygen.

The mower consists of an engine for generating power, a rotary blade that rotates with the power generated by the engine, and an axelator lever for adjusting the rotational speed of the blade.

The engine is usually designed to be carried on the back of the user, and the rotary blade is coupled to the connecting rod coupled between the engine and the rotary blade. Therefore, the user cuts the weeds by moving the rotary blade to the left and right while attaching the mowing machine to the back and close the rotary blade attached to the end of the connecting rod through the handle attached to the connecting rod close to the ground.

However, when mowing, the ground where grass is grown is not only flat, but rubble or tree branches are exposed to the ground in addition to weeds, so blades that rotate at high speed collide with rubble or tree branches, causing rubble or broken blades. Injuries are often caused by debris. Of course, there is also a problem that the blade is easily worn.

Therefore, when cutting grass or mowing the grass grown in an irregular place, the height of the cut grass is not constant, it is difficult to neatly and neatly mowing.

For example, lawn mowers usually have four wheels and an engine attached to them, and a blade that rotates between the engine and the ground is installed to cut the grass so that the blade rotates at a constant height at a constant length. However, most mowing machines are not only constant cutting length of the weeds, but also digging up rubble, tree branches or small roots in the soil because the user cuts the weeds by holding the hand with the rotating blade and moving the support from side to side. Etc. There has been a problem that skilled techniques are required in the handling thereof.

In order to solve this problem, two wheels are provided separately from the mower, and the support blade (rotary blade part) of the mower is attached on the mower to the shaft connected between the two wheels, and then the front and back of the support are rolled, and the rotary blade is rolled. Rotating blade height support devices for cutting aids have been developed that can be mowed with a certain height from the ground.

For example, the Republic of Korea Utility Model Publication No. 2000-0006747 (2000.02.07) "portable mower wheels" as described above, the rotary blade is attached to the mower, the supporter is mounted on the cradle rather than holding the support by hand, the ground blade A technique for cutting weeds while floating at a constant height has been disclosed.

The present invention is a mowing machine that can be attached to the support shaft attached to the rotary blades to remove the weeds (including grass and young trees) to mowing the cutting blade, so as not to work when the mowing operation of the weeds (including grass and young trees) In order to selectively attach the mounting position of the support of the rotary blades to provide a support holder for mowing machine to selectively select the separation distance from the ground.

The mower support holder according to the present invention is provided with a semicircular support groove having different heights on the upper and lower surfaces of the shaft and the shaft connected between the two wheels and the wheels, and are superimposed on the semicircular support groove and attached to the semicircular support groove. A fastening band having a semicircular support groove to fix the positioned support; It is implemented by configuring as a fastening means for fastening and disassembling the fastening band.

The present invention can be attached to any one of the two grooves of the upper and lower when attaching the support attached to the rotary blade of the mowing machine to the semi-circular support groove symmetrically installed on the surface of the shaft. In this case, there is an effect of adjusting the height of the rotary blade is separated from the ground to provide an effect that can change the cutting length of the weeds.
