Description

[Detailed Description of the Invention] This invention relates to a resistance rod that also serves as a stand in a small-sized management machine.

In recent years, small-sized farm management machines have become commercially available, particularly for use in small-scale farm fields, such as those used in home gardens. This type of small-sized gardening machine has a built-in centrifugal clutch so that it can be used by both women and women, and when the engine speed increases by operating the accelerator, the clutch connects and allows plowing work, but on the other hand, it is easy to operate the accelerator incorrectly. The tiller rotates at the same time as the engine starts, and this rotation causes the machine to run out of control. In addition, when replacing the tiller attachment, women and girls had the disadvantage of requiring a great deal of effort, as they had to place the machine on its back to replace it.

Therefore, this invention was devised to maintain and improve the function of the conventional resistance rod, and also to have the function of a stand.

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

The main parts of this type of small control device include a main body 1, a frame 2, an operating handle 3, a resistance rod 4, etc.

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. Machines 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 resistance rod 4 has a bifurcated structure, and when used as a stand, the cultivating portion 7
Both are bent in the same direction from a position sufficient to levitate the stand to form a support surface running resistance portion 4a.

The attachment relationship between the rod 4 and the frame 2 is as follows.

That is, the base 4b of the rod 4 can be rotated in the front-rear direction by a support cylinder 9 fixed to the lower end of a vertical position adjustment rod 8, which is attached to the rear end of the frame 2 so as to be movable and fixed up and down. Regulating pieces 10 and 11 are fixed to the outer circumferential surface of the supporting cylinder 9, and are supported at appropriate positions to restrict the rotation of the rod 4 in the front-rear direction. Further, spring mounting pins 12 and 13 are protruded from the rod 4 and the vertical position adjustment rod 8, respectively.
A spring 14 is interposed between both pins 12 and 13.

To use the resistance rod 4 having the above configuration, first,
The rod 4 is forcibly rotated from the rear to the front around its base 4b, that is, the rotation fulcrum P of the rod 4, until the spring 14 crosses the fulcrum P, and after passing the fulcrum P. Due to the biasing force of the spring 14, the machine rotates forward to the restricted position and is fixed at the solid line position shown in Figures 1 and 2, raising the tilling section 7 and assuming a stand posture, and the machine is supported by the rod 4 and safely secured. It becomes possible to start the engine or replace the attachment of the tiller 7.

Next, the engine started in the above-mentioned stand position is rotated at a low speed by depressing the accelerator, and then the rod 4 is rotated from the front to the rear in the opposite direction to that described above. That is, the rod 4 is forcibly rotated until the spring 14 passes the rotation fulcrum P, and after passing the fulcrum P, the rod 4 is surely rotated to the rearward regulating position by the biasing force of the spring 14 and fixed, and the tilling work is performed. In this position, the tiller 7 can perform tilling work by gradually depressing the accelerator. In this case, the rods 4 act as a running resistance, allowing suitable tillage work depending on the geological condition of the soil.

As is clear from the above explanation, this invention has a structure in which the conventional resistance rod used in small control machines can also be used as a stand, so the number of parts can be reduced, and the resistance rod 4 can be placed in the front. When used as a stand by rotating the tiller, attachments such as the tiller 7 can be replaced very easily. Even if the engine is started while the accelerator is being pressed, the tiller section 7 will rotate at the same time as the engine starts. Since the tiller section 7 will be raised above the ground in the stand position, the engine will start safely without the danger of running out of control. It has now become possible to do so.

Further, when the stick 4 is rotated rearward to perform plowing work, since the stick 4 is bifurcated, the left and right balance is improved.

Furthermore, since the biasing force of the spring 14 is used to rotate the rod 4 back and forth, the rod 4 can be rotated reliably to the rotation restriction position.
