Description

Rotary blade supporter for lawn mowers {SADDLE FOR POTABLE CUTTER}

The present invention can selectively change the rolling direction so that the wheel of the cradle attached to the lawn mower can be rolled back and forth or left and right, and the blade for the mower can align the blade mounted on the cradle with the ground approximately horizontally. It relates to a knife supporter.

Mowers are used in various ways, such as weeding and weeding quickly when weeding, farming, or mowing gardens.

The mower is configured to generate power in the engine, the power being transmitted through the flexible tube and the tubular shaft so that the blade coupled to the end of the tubular shaft is rotated. The blade is rotated by the power of the engine, which is coupled to the end of the tubular shaft and transmitted therein. In the middle of the tubular shaft, a hand-held handle and an axle lever for controlling the rotational speed of the blade are provided.

Usually, the mower is mowed by the blade which rotates at high speed by moving the blade from side to side with the operator holding the engine back and holding the handle with both hands.

However, as the mowing operation requires the tubular shaft to be held by hand as described above, the blade must be moved away from the ground to prevent the rotating blade from touching the ground. It is very difficult to mow while keeping them apart from the.

The reason for this is that the unskilled person does not sense the separation distance between the ground and the rotating blade. Therefore, during the mowing operation, the rotating blade digs the ground, and the cut height of the grass is irregular, so that neat mowing operation is possible. Most of the time, it is not done, and due to immaturity of the usage, the blade fragments broken by rubble, wood chips or a collision of the blades are seriously injured.

In summary, if you move to a constant distance from the ground of the blade of the mower, the cutting length of the weed can be even and neat mowing work, but it is difficult for beginners to grasp the distance of the blade from the ground, neat and tidy There is a problem that is difficult to mow.

In order to solve this problem, in order to keep the blade of the lawn mower at a certain height from the ground, as shown in Figs. 1a and 1b, the wheel on the tubular shaft 1, that is, the tubular shaft 1 to which the blade 2 is attached An auxiliary lawn mower 4 for lawn mowers has been proposed to auxiliaryly attach the cradle 4 to which (3) is attached so as to artificially maintain the gap between the ground and the blade 2.

However, as shown in FIG. 1B, the conventional mower auxiliary holder 4 is mainly fixed in shape so that the wheel 3 only rolls from side to side, and some auxiliary holders are installed such that the wheels only roll in the horizontal direction. There is one, but the existing auxiliary cradles are fixed to roll only one direction, so that the mowing operation does not correspond to the environment to change the movement direction of the blade from time to time, the movement is not easy.

On the contrary, Patent Publication No. 2000-6747 discloses an auxiliary cradle installed so that the wheels only roll back and forth, which has the problems described above.

In addition, as shown in FIG. 1A (see Utility Model Registration No. 256445, "Horning Machine" notification date December 24, 2001), wheels 3 are installed at four positions so that the blade 2 is located at the center, and the upper part of the blade is protected. A mower auxiliary holder 4 covered with a cover 5 has also been developed.

In the case of the cradle (4) to which the four wheels (3) are attached, the four wheels all touch the ground, so the blade (2) always maintains a constant distance from the ground. When cutting grass grown around obstacles such as trees or trees, the blade (2) is caught by obstacles, so that the blade (2) cannot enter, and mowing is difficult. Also, all four wheels must touch the ground. It is uncomfortable because it is unnatural.

In addition, the mowing work is carried out by mixing in the front and rear direction, the horizontal direction or the front and rear direction, but when the blade 2 rotating at high speed rotates counterclockwise, the mowing machine is leftward and the blade 2 is clockwise. In the case of rotation in the direction of the blade (2) to move to the right direction to mow the most efficient mowing work, but the conventional mower auxiliary cradle (4) is the forward direction of the wheel (3) front and rear or left and right Direction It is fixed to roll in only one direction, so the movement of the blade is limited, the workability is bound to be limited.

In addition, the shaft with the auxiliary holder is a posture holding the shaft during the mowing operation, that is, if the inclination of the shaft is not appropriate, the blade is positioned diagonally with respect to the ground may cause a problem that the rotating blade to dig the ground.

Therefore, it is desirable that the angle of use of the shaft does not vary so that the blade is parallel to the ground when the mower is used, but since the blade is fixedly attached to the shaft, the inclination of the shaft is appropriately set during cutting work, that is, the blade is parallel to the ground. When attaching the auxiliary support to the tubular shaft, it is necessary to properly adjust the attachment angle of the auxiliary support in consideration of the angle of use of the shaft.

The present invention is devised to solve the problems as described above, the object of the present invention is a cradle that is attached to the tubular shaft attached to the blade to mow the blade of the rotary mowing machine spaced apart from the ground It is to provide an auxiliary cradle for the blade support of the lawn mower that the user can arbitrarily change the rolling direction of the wheel.

Another object of the present invention is to adjust the inclination of the tubular shaft mounted on the auxiliary cradle so that the blade attached to the end of the blade is placed approximately parallel to the ground so that the blade does not dig into the ground, and the height of the cut grass or weed is uniform. It is to provide an auxiliary holder for the blade support of the lawn mower capable of adjusting the angle so that the cutting can be made consistently.

Another object of the present invention is to provide an auxiliary holder for blade support of a mower, which is further attached with a protective cover for protecting the worker from rubble or wood debris during mowing.

Implementing means for achieving the blade holder of the blade support auxiliary according to the object of the present invention is detached to the tubular shaft of the lawn mower to maintain the blade of the lawn mower to a certain height from the ground, rolled in a straight or transverse direction In the auxiliary holder of the lawn mower having a thin wheel,
