Description

[Detailed description of the invention] (Field of industrial application) This invention belongs to the field of cutting, and is used for mowing grass along roadsides, etc.

(Prior technology) Conventional power mowers (consisting of a mower body and a cutter head) are used by hanging from the waist, so fatigue due to the weight load accumulates and long mowing work is required. In addition, there were deficiencies such as poor work efficiency when mowing the grass on the side of the road because the working posture was uncomfortable.

(Problems to be Solved by the Invention) In view of the above-mentioned circumstances, the technical objective of this invention is to provide a grass cutter that can cut grass in a comfortable working position even for long periods of time.

(Means for solving the problem) This invention is a mower consisting of a mower body and a cutter head, in which one end of the power transmission part of the mower body is locked to the middle part of the unicycle frame so that it can swing vertically and horizontally. A plurality of positioning stators are erected at the tip of the frame at required intervals in the left-right direction, and the other part of the power transmission section is rotated about the axis of the power transmission shaft between the stators. It is fixedly locked.

(Function) According to the above configuration, the unicycle reduces the weight load on the operator of the mower, and the positioning stator allows the cutter to be positioned and held in alignment with the inclination angle of the left and right side surfaces.

(Example) To explain this invention in detail based on an example, as shown in FIG. A bearing part 4 is installed upright in the section to pivotally support one end of the outer cylindrical pipe 7 in which the power transmission shaft in the power transmission part connecting the engine part 5 and cutter head 6 of the mower body a is loosely mounted. ing. At this time, the outer cylindrical tube 7 can be freely swung up and down on the horizontal axis 8 of the bearing part 4, and can be swung left and right on the vertical axis 9.
is locked. At the tip of the frame 2, a plurality of positioning stators 10 are erected at required intervals on a member extending horizontally in the left-right direction, and between the stators 10, a square tube integrally covered with the outer tube 7 is provided. 11 can be freely inserted and removed to maintain the desired position of the cutter head 6. That is, in the case of mowing the upper surface of a road, etc., the rectangular tube 11 is locked between the positioning stators 10 in the center as shown in FIG. Note that the cutter 13 is rotated in the counterclockwise direction in FIG. 2. Next, when mowing the left side of the road, proceed as follows. That is, the second
When the outer cylindrical tube 7 is lifted from the state shown in the figure, the outer cylindrical tube 7 of the mower main body a swings upward about the horizontal axis 8. In this state, the cutter head 6 is moved to the third position at the joint part 12 of the outer cylinder tube 7, centering on the axis of the power transmission shaft.
As shown in the figure, the cutter 13 is rotated to the right so that it cuts upwardly, and at the required rotational position, the rectangular tube 11 is locked between the positioning stators 10 installed on the left side, and the attitude of the cutter head 6 is changed. Fix it. In this state, if you move back and forth while operating the handle 3,
After mowing the left side first, on the return trip, the right side is mowed as is, allowing you to mow the left and right sides in the same comfortable posture as when mowing a flat surface. When mowing the grass on the side surface, the angle formed by the blade surface of the cutter 13 and the center of the mower (the direction of movement of the mower) is approximately in the range of 15° to 30°. In addition, the positioning stator 10 can not only be installed integrally with the frame 2, but also can be installed upright so that the vertical installation angle can be freely changed and adjusted.
In this case, use the cutter 13 at the angle of the side mowing slope.
This means that the blade surface can be adjusted accordingly.

(Effects of the invention) As described above, according to this invention, the conventional mower body a can be used without modification, which not only reduces the operating burden on the operator, but also makes mowing work more efficient and easier. It has the effect of
