DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soil management machine suitable for cutting grass under a fruit tree.

[0002]

2. Description of the Related Art Many fruit trees have low branches and leaves and hang down (especially mandarin orange trees).
Therefore, if the grass is cut by a conventional management machine or mower equipped with a rotary work body for ground work, the branches and leaves interfere with the grass and the grass cannot be cut well. In addition, forcible work will damage branches and leaves. On the other hand, this type of soil management machine requires a stand that temporarily stands up when not working. Further, when a load is applied to the rotary work body, a resistance bar is required.

The present invention has been made to solve such a problem. Although the present invention is provided with a stand also serving as a resistance bar, the stand is changed from a member having an original stand function to a specific position capable of working even in a very low position. It can be changed.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a soil management machine having a rotary working unit and a handle extending rearward and upward from the rotary working unit.
The handle is equipped with a stand that doubles as a resistance bar that can be switched between a working position that holds the soil management machine in a standing position at a predetermined angle with the handle and a storage position along the bottom of the handle. And provide a soil management machine.

[0005] When the stand is in the working posture by the above means, the soil management machine (hereinafter referred to as the management machine) is maintained in a constant standing posture. Further, since this stand is held in the working posture, it can also be a resistance bar. On the other hand, when the stand is in the retracted position, the stand is formed along the bottom of the handle, so that the work does not hinder the work, and the low-height work with the handle lowered can be performed. Therefore, weeding under short trees can be performed.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a management machine showing an example of the present invention, and FIG. 2 is a rear view. This management machine is provided with a cover 14 in the middle of a transmission cylinder 12 having an engine and a clutch 10 connected to the upper end. A rotary work unit 18 having a rotary work body 16 having a horizontal axis attached to a lower end below 14 is provided, and a steering handle 20 extending rearward and upward from the transmission cylinder 12.

In this case, the rotary working body 16 also serves as a running wheel, and in addition, a tilling blade or a cutting blade is attached to the rotary working body 16 depending on the working purpose. In this case,
A mountain-shaped cutting blade is attached to the outer periphery of the drum when viewed from the front. When the cutting blade is rotated by the driving force of the engine 10, the ground is shallowly plowed to cut grass. At this time, when a resistance bar, which will be described later, is acted on, the amount of idling of the rotary work body 16 increases, and deep plowing is performed.

In the present invention, a stand 22 described below is attached to the handle 20 described above. The stand 22 has a working posture for holding the management machine in a standing posture,
The storage position is switched to a storage position that does not obstruct the work. Specifically, the mounting bracket 2 having the horizontal fulcrum shaft 24
6 is attached to a handle 20, and a stand 22 is attached to the fulcrum shaft 24 so as to be able to rotate back and forth.

In this case, the stand 22 is pulled slightly backward,
The work posture (A) is when the body is supported at a predetermined angle with the handle 20, and the storage posture (B) is when the stand 22 is rotated forward and along the bottom of the handle 20. The stand 22 is configured so that both the working posture (A) and the storage posture (B) are held at that position with a certain force, and when the posture is switched, the external force is released.

FIG. 4 is a partial cross-sectional side view of the mounting bracket 26, FIG. 5 is a cross-sectional view, and FIG. 6 is a cross-sectional view of the stand 22. The stand 22 is in the working posture (A) and the storage posture (B), respectively.
The bag-like positioning tool 2 which resiliently receives the stand 22 at the position of the mounting bracket 26 and does not rotate it any more
8, 30 are provided for positioning. Therefore,
In this case, the openings of the positioning tools 28 and 30 are opposed to each other. When the stand 22 in the working posture (A) is used as a resistance bar, in order to receive a large load, in addition to the positioning tool 28, a stopper 32 for restricting further rotation of the stand 22 is attached to the mounting bracket 26.
Is provided.

In this case, the handle 20 is divided into a base side handle 20a and a hand side handle 20b.
A box 34 is installed at the tip of the root side handle 20a,
The hand-side handle 20b is inserted and connected to this. That is, holes and screw portions 36 are provided on the upper and lower surfaces of the insertion portion of the hand-side handle 20b, respectively. And screwed into the screw portion 36 (a hole is formed at the position where the knob screw 38 of the hand side handle 20b is inserted). In addition, an auxiliary handle 40 also serving as a handle is provided on the upper surface of the mounting bracket 26.

As described above, the stand 22 is moved to the positioning tool 2.
When the work machine is set in the working posture (A) by fitting it into the working position 8, the management machine is maintained in a constant standing posture, and this posture may be taken when work is temporarily stopped or stored. In addition, the stand 22 in this position also serves as a resistance bar, enabling heavy work. FIG. 3 is a side view of the management device when the stand 22 is in the storage posture (B). When the stand 22 is removed from the positioning tool 28 and is fitted into another positioning tool 30 to be in the storage posture (B). Since the stand 22 is formed along the bottom of the handle 20, the handle 20 can be lowered drastically, and mowing or the like can be performed under a short fruit tree.

By the way, the mounting of the stand described above is only an example, and the present invention is not limited to this. What is essential is that the stand can be switched between the working posture and the storage posture described above and can be held in that posture. It may have a simple structure.
For example, it is not necessary to use the mounting bracket, and the stand may be replaced with a specific part when the posture is changed, or a pin may be inserted and held instead of the positioning tool.

Further, the stand may be constantly biased toward the storage position by a spring or the like. Can be retained). Further, the stand has one stand in the previous example, but may be constituted by two or more stands.

[0015]

As described above, according to the present invention, when the stand is in the working posture, the management machine can be maintained in a constant standing posture and can be a resistance bar. On the other hand, when the stand is in the stowed position, the stand is formed along the bottom of the handle, so that it does not hinder the work, and the height of the stand can be lowered by lowering the handle.
