Description

[Detailed Description of the Invention] This invention relates to a support leg/resistance rod for a small-sized control aircraft.

In recent years, small-sized farm management machines particularly suited for use in small-scale farm fields, such as those used in home vegetable gardens, have become commercially available. This type of small-sized gardening machine has a built-in centrifugal clutch so that it can be used by both women and men, and when the engine speed is increased by operating the accelerator, the clutch engages and allows plowing work, but on the other hand, it is easy to operate the accelerator incorrectly. The tilling section rotates at the same time as the engine starts, and this rotation causes the machine to move violently.

Therefore, this invention eliminates this drawback and allows the user to quickly shift to the normal tilling work position.

Hereinafter, embodiments of this invention will be described based on the drawings.

The main parts of this type of small-sized management machine include a main body 1, a frame 2, an operating handle 3, and a resistance rod 4 that serves as a support leg for standing the machine.

The main body 1 consists of an engine 5, a centrifugal clutch (not shown), etc. mounted on the frame 2, and a cultivating section 7 mounted below the frame 2 via a transmission 6. are used. The same applies to the operating handle 3 extending diagonally to the rear of the main body 1 from the rear of the frame 2.

The aircraft standing support leg/resistance rod 4 has a bifurcated lower part and is curved as a whole.
Its base is supported by eight shafts at the rear of the frame 2, and is rotatable in the front and rear directions. The rotation of the rod 4 in the front-rear direction is regulated by stoppers 9 and 10 fixed to the frame 2. In addition, 11 in the figure is the rod 4
12 indicates an accelerator lever. Further, the rod 4 may be formed of a single rod instead of two, such as a round rod or a round pipe.

In use, the invention is implemented as follows.

That is, when starting the engine 5 of this machine, the operator first presses both lower ends of the legs and resistance rods 4 into the ground to create a stable floating support fulcrum P of the tilling part 7. After operating the handle 3, when the handle 3 is pulled toward the worker, the bar 4 rotates forward, and as shown by the solid line in FIG. Together with the support of both lower ends, the machine is in an upright support posture, with the tilling section 7 floating above the ground.
Incidentally, this upright supporting posture of the aircraft can also be achieved by inserting the two lower ends of the rod 4 into the ground.

Next, after safely starting the engine 5 in this floating state (state A shown by the imaginary line in Fig. 3), the accelerator is slightly increased and the tiller 7 is slightly rotated until the handle 3 moves away from the operator. The tilling section 7 rotates and moves forward by simply rotating the support fulcrum P as the center of rotation until the tilling section 7 touches the ground and starts tilling work and starts moving forward (state B shown by the solid line in Fig. 3). The rod 4 rotates backward accordingly and assumes the normal tilling work posture (C shown by the imaginary line in Fig. 3).
state).

As is clear from the above explanation, this invention has a configuration in which the conventional resistance rods used in small control machines can also be used as the aircraft's standing support legs. can now be started safely in the upright supporting position of the machine by rotating the rod 4 forward and raising the tiller 7 above the ground. This eliminates the danger of starting the engine while the accelerator is pressed, causing the tiller 7, which is in contact with the ground, to rotate at the same time as the engine starts, causing the machine to run out of control.

After starting the engine in this aircraft standing support posture, the operator turns the handle 3 around the floating support fulcrum P at the lower ends of the bifurcated rod 4 to the position where the tiller 7 starts plowing and moves forward. The tiller 7 rotates and moves forward simply by the tilting operation, and the rod 4 accordingly rotates rearward, making it easy to shift to the normal working position.
