Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a portable, simple cutting machine that is supported by wheels and can be cut while cutting the edge of a field while traveling.

[Prior Art] Conventionally, cutting along the shore has been performed manually by a shovel or a hoe.

[Problems to be solved by the invention] Therefore, in manual work using a shovel, a hoe or the like, it is difficult to orderly and cut well, and moreover, heavy labor causes poor workability.

[Means for Solving the Problem] The present invention solves such a problem and further improves the work efficiency. Therefore, the engine portion is connected to the rear end portion. A horizontal gear case is connected to the end of a long operating rod that incorporates a transmission shaft, and the end of the gear case has a small diameter wheel and a large diameter disc blade that can be driven in opposite directions with the same shaft center. do it,
It is designed so that it can be cut off along the shore.

[Operation] Therefore, it is possible to carry and operate the operation stick conveniently, and when working, hold the operation stick and move it forward with the wheels. The work can be cut in an orderly manner and safely without causing the work piece to scatter.

Example Next, an example shown in the drawings will be described.

In FIG. 1 and FIG. 2, FIG. 1 shows a perspective view of the whole, in which the engine part (1) is connected to the rear end of a long operating rod (3) having a transmission shaft (2) installed therein. The handle rod (7) and the grip (8) are attached to the rear part of the rod (3),
A shoulder strap can be connected to the hanging metal fitting (9) at the front of the grip (8) so that it can be carried and operated.
It is constructed in the same way as a conventional brush cutter.

(4) A gear case formed in the shape of a dogleg, in which the tip end of the operating rod (3) is fitted to the inclined upper part of the gear case (4) and the tightening bolt (10a) and the locking bolt (10b) are provided. ), The first drive shaft (11), which is fixed by
The cylindrical second drive shaft (12) fitted to the first drive shaft (11) is mounted via a bearing (13), and the first drive shaft (11) The bevel gear (14) fitted and fixed to the end side and the bevel gear (15) fitted and fixed to the inner end side of the second drive shaft (12) extend from the inside of the operating rod (3). The transmission shaft (2) is engaged with a bevel gear (16) fitted and fixed to the tip of the transmission shaft (2).

Further, a boss (17) that also serves as a seal spline-fitted to the second drive shaft (12) is locked by a nut (18) screwed to the tip of the second drive shaft (12), and the boss (17) ), A small diameter wheel (5) is fixedly mounted on the outer periphery of the first drive shaft (11).
The central part of the large-diameter disc blade (6) is placed between the holding plate (19) fitted and fixed to the tip of the disk and the holding plate (20) fitted to the first drive shaft (11). A clamping nut (22) is abutted and configured on a support plate (21) which is brought into contact with the outside of the holding plate (20) by being fitted.

FIG. 3 shows another embodiment, which has substantially the same structure as that of the above embodiment as indicated by the same reference numeral, but has an intermediate shaft (23) which is vertically mounted above the first drive shaft (11). A bevel gear (24) that meshes with both the bevel gears (14) and (15) is fitted and fixed to the lower part of the bevel gear (24), and a bevel gear (25) that meshes with the bevel gear (16) is provided above the bevel gear (24). Are fitted and fixed.

Therefore, the wheel (5) and the disc blade (6) are transmitted from the transmission shaft (2) in the operating rod (3), and the wheels (5) and the disc blade (6) rotate in reverse at the same speed or rotation difference.

Therefore, the operator can conveniently carry and operate the operation rod (3), and at the time of work, the operator can operate the operation rod (3).
When moving forward with the wheels (5), the disc blade (6)
While rotating in the up-cut type, it is possible to cut the cut edge in an orderly and safe manner by preventing the cut object from scattering to the operator side.

[Effects of the Invention] As described above, the present invention allows the operator to conveniently carry and operate the operating rod (3), and at the time of work, while grasping the operating rod (3) and moving it forward with the wheels (5), By rotating the disc blade (6) in an up-cut type, it is possible to cut the material safely and satisfactorily without breaking the shore, etc. It has a feature that it can be suitably implemented with a simple structure.
