Description

[Detailed description of the invention] The present invention relates to a grass cutter, particularly a long-stem grass cutter, and its purpose is to easily construct a grass cutter that cuts loosely sown grass without leaving anything uncut and knocks it to one side. shall be.

To specifically explain the embodiment shown in the drawings, a cutter disc 3 is attached to the lower end of a cutter shaft 2 erected at the front of a machine frame 1, which is equipped with an operating handle and an engine (not shown in the figure) at the rear. multiple cutlery 4
Install. A suitable conveyor frame 6 such as a rhombus, an inertia, a triangle, etc. is attached to the upper part of the cylindrical frame 5 which is erected on the upper surface of the machine frame 1, and a conveyor belt 7 is wrapped around it in the recess 6a.

The engine not shown in the diagram includes wheels 8, cutter disc 3,
When moving forward while driving the conveyor belt 7, the cutter 4 cuts the cutting material at its root, and the crop is conveyed above it to the conveyor belt 7 rotating in the same direction as the blade disk 3 and pushed down in the conveyance direction.

With this kind of reaper, if the grass is planted in rows, it will be cut without leaving anything behind and the grass will be cut to one side, but in the case of sowing in bulk, there will be no parting, so there will be some uncut grass, and the grass will be cut to one side. There are also some inconveniences such as having uncut leaves standing up.

Therefore, in the present invention, the blade disk 3 is
The reaping rod 9, which is slanted toward the approximate center of the cutter disc 3 from the outside front, is placed between the cutter disc 3 and the carrier 6 from the machine frame 1 or cylinder frame 5 using the L-shaped arm 9a. It was established as follows.

As the reaper advances, the densely grown harvested material is also raked into the blade disk 3 by the diagonal side 9 of the raking rod and cut by the blade 4, and is cut by the diagonal side 9 and the L-shaped arm 9a. There will be no uncut areas outside the apex 9b. Therefore, there is an advantage that there will be no inconvenience if you move it in that direction.

Although any transmission mechanism may be used, in the illustrated example, engine power is transmitted to the blade shaft 2 and the carrier drive shaft 13 by bevel gears 10 to 12. From the shaft 13 to the gear 14
15 to a belt drive pulley 16 to rotate the belt 7.
