Description

Mowers {WEEDER}

The present invention relates to a mower.

The mowers mow weeds mainly by blades that rotate at high speed.

Such mowers typically consist of a motor, a tubular member, and a blade. When the operator lifts the motor on the back and moves the left and right sides of the tubular member, the weed is cut while the blade rotating at high speed by the power of the motor touches the weed.

Lifting the tubular member to a constant height, the mowing operation is in progress with the blade off the ground. However, for those who are not used to mowing with a mower, it is difficult to keep the blade at a constant height off the ground.

Due to this, the blades rotate at high speed during the mowing operation to dig the ground, and the height of the cut weeds was irregular, neat mowing was not made.

In addition, the damage caused by the debris generated when the blade hit the stone during the mowing operation.

The problem to be solved by the present invention is to provide a lawnmower that allows the blade to rotate at high speed to maintain a constant height from the ground, the height of the mowed weeds to be constant.

A mowing device according to an embodiment of the present invention is a tubular member, a blade connected to one end of the tubular member, a motor connected to the other end of the tubular member and rotating the blade, and connected to one side of the tubular member. A mounting device, wherein the mounting device is spaced apart from each other, and the first and second support members, the first support member and the second support member, on which the blades are located, are coupled and one side of the tubular member. A connection device positioned at a plurality of holes and surrounding the tubular member, and both ends of which are inserted into the hole, wherein the connection panel of the first and second support members is coupled thereto. The part is inclined at a predetermined angle.

The first support member and the second support member are broken and divided into upper and lower members, respectively, and the upper and lower members may be connected to at least one height adjusting member.

The height adjusting member is located between a first threaded portion connected to the upper member, a second threaded portion connected to the lower member and opposite to the first threaded thread direction, and between the first threaded portion and the second threaded portion. At least one portion of the first screw portion is fastened to one end, and at least one portion of the second screw portion may include a nut fastened to the other end.

The height adjusting member is connected to the lower member and having a plurality of through holes, a fixing rod connected to the upper member and having at least one portion inserted into the fixing tube and having a plurality of coupling holes, and the through It may include a ball and a fixing pin inserted into the coupling hole.

The height adjusting member is connected to the lower member and has a first fixing member having a length thereof formed therein, a second fixing member connected to the upper member and having at least one portion inserted into the first fixing member; and It may include a buffer member surrounding the first fixing member and the second fixing member, one end is coupled to the upper member and the other end is coupled to the lower member.

Further comprising a plurality of wheels coupled to the lower member, the wheel may include a body coupled to the lower member and freely rotated, coupled to the body and roller rolling.

The apparatus may further include a plurality of protection panels coupled to the outside of the first and second support members.

The apparatus may further include an auxiliary connection bar that is separated from the connection panel and has one end coupled to the first support member and the other end connected to the second support member.

According to an embodiment of the present invention, a tubular member having a blade coupled to one side is mounted on a mounting device, so that the operator does not have to lift the blade off the ground during mowing operation, thereby facilitating the operator's convenience.

According to an embodiment of the present invention, wheels are coupled to lower members of the first and second support members to improve the mobility of the mounting apparatus.

According to the embodiment of the present invention, by the tubular member mounted on the mounting apparatus is maintained at a constant distance away from the ground to the blade can be kept neat mowing work by maintaining a constant height of the weeds cut by the blade.

According to an embodiment of the present invention, as the height adjustment member adjusts the distance between the upper and lower members of the first support member and the second support member, the blade falling off the ground can be adjusted to reduce the height of the cut weeds. Can be cut to height.

According to an embodiment of the present invention, the debris generated when the blade hits a stone during mowing, is blocked from going out by the protection panel to promote the safety of the worker.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Like parts are designated by like reference numerals throughout the specification.
