Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a simple mower that can be applied to, for example, roads along banks and around fields.

(Conventional technology) Weeding around banks, roads, and fields has long relied on manual work using mowing sickles, but in recent years, with the spread of mechanized agricultural tools such as motor-driven cutters, weeding has become easier. Conditions have been significantly reformed.

However, even if relatively vast grasslands and flat mountains can be efficiently mowed using the mechanized cutters mentioned above, relatively narrow ridges, roadsides, etc. with extremely uneven, sloped, or curved surfaces can be mowed efficiently. Large aircraft are not suitable for areas around fields.

(Problems to be solved by the invention) This invention is an easy-to-use and inexpensive push-open/close type simple mower that can be used in relatively narrow spaces where large machines such as those mentioned above are unsuitable. This was done for the purpose of providing it easily.

(Means for Solving the Problems) The mower according to this invention has tips joined with a hinge structure so as to be openable and closable, forming long cutting blades facing each other, and one of which has a sheath-like cross-sectional shape. It consists of two main bodies, the other of which is plate-shaped, with a long operating handle extending upwardly provided at its base, and a guiding wheel attached to its distal end joint.

(Function) In this invention, mowing is performed by placing the guide wheel along the ground and pushing it forward or pulling it in the opposite direction while opening and closing the operating handle.

(Embodiment) An embodiment of this invention will be described below based on the drawings. That is, 1 is a sheath-like main body, which has a U-shaped cross section as shown in FIG.
is formed. Reference numeral 3 denotes a plate-like main body, which has a length equivalent to that of the sheath-like main body 1 and forms a cutting blade 4 opposite to the cutting blade 2. By the way, both main bodies 1,
No. 3 has its tip portion joined by superposition, and this portion is connected with a hinge structure 5 so as to be openable and closable. In addition, in order to make the opening degree as large as possible over the entire length when the two main bodies 1 and 3 are opened and closed to perform mowing operation, this joint part is formed by, for example, protruding the tip of the sheath-like main body 1 to one side. This protrusion 6 is used to connect the plate-like main body 3. In other words, the hinge structure portion 5 is deviated to one side. Such deviation can also be achieved by causing the tip of the plate-like body 3 to protrude to one side, contrary to the embodiment shown in the figures.

Reference numeral 7 denotes an operating handle provided at the base end of both the main bodies 1 and 3, which allows the operator to maintain a suitable posture, that is,
Both main bodies 1 and 3 are held almost horizontally to the ground in an almost upright position, and the handles 8 are extended upward to the extent that they can be opened and closed, and the handles 8 provided at the tips are spaced at an appropriate distance below the shoulder width of the worker. is set to .

9 shows a guide wheel attached to the front end of the sheath-like main body 1. In the embodiment, an operation screw 11 is screwed into the support member 10 fixed to the sheath-like main body 1, and the guide wheel 9 is attached to the tip of the operating screw 11. Although the structure of this part is not particularly limited, for example, as shown in FIG. 4, the support member 10 may be extended from the hinge structure 5. It's okay. Although not shown, the guide wheel 9 may be a deflection wheel whose support shaft rotates arbitrarily.

Furthermore, if the operating handle 7 of this invention is provided with a joint that can be extended or contracted in the middle thereof, the length can be adjusted according to the back height of the operator. In addition, in the embodiment shown in the figure, the plate-like main body 3
Although the case where the cutting edge 4 is formed into a saw blade shape is shown, this may be formed into a straight blade shape, and furthermore, the cutting edges 2 and 4 of both bodies 1 and 3 may be formed into a saw blade shape, etc. The selection is arbitrarily determined after taking into account the characteristics of the grass to which this machine is applied.

(Effects of the invention) As explained above, this invention consists of two main bodies with long cutting blades that serve as fulcrums for opening and closing, with operating handles attached to the base ends, and a guide wheel attached to the tips. Since the structure is simple, it can be provided at a low cost, and the operator can open and close it in an almost upright position by pushing it forward or pulling it in the opposite direction, thereby cutting the grass between the two cutting blades 2 and 4 and cutting it to the target. Grass mowing can be accomplished easily. Furthermore, this device does not require any special operating skills and can be easily handled by anyone regardless of age or gender, making it very suitable for general household use.
