2. Description of the Related Art Conventionally, an emergency stop device in a tiller has been
A cultivator in which the switch means is attached to the front engine body or the stop switch is attached directly to the pipe handle with a clip band, for example, is already known.

[0003]

In the cultivator in which the emergency stop device for the cultivator is mounted on the engine body in the front, which is already known, the switch means is not located near the steering section of the steering wheel. I can't make it in time for the stop. In a cultivator in which the switch means is attached directly to the pipe handle with a clip band, for example, not only is the contact of the wiring exposed and the appearance is poor, but it is also necessary to prepare a clip band that matches the diameter size of each pipe handle. there were.

The fixing substrate (14) is covered with the mounting cover (16) from above the handle (10), and the mounting cover (16) is fixed from below to solve the above-mentioned problems. Settled.

[0005]

Based on the above structure, the handle (1
The fixed L-shaped fixed substrate (14) is welded to the outer surface of (0),
On the other hand, the switch means (1
Mounting cover (16) incorporating 5) and wiring (19)
Is covered from above the fixed substrate (14) and the handle pipe (10), the switch means (15) main body is housed in the space formed by the fixed substrate (14) and the mounting cover (16), and the mounting cover (16) is placed from below. ), The bosses (16a) provided before and after the fixed substrate (14) are fastened to complete the assembly.

In an emergency during driving, the above-mentioned steering wheel (10)
When the switch button (15) attached to the hand is pushed with a finger, the rotation of the engine (1) can be stopped via the wiring (19).

The reference numerals in parentheses are for the purpose of contrasting with the drawings, but do not limit the structure of the present invention.

Embodiments of the present invention will be described below with reference to the drawings.

The cultivator 1 transmits the power of the engine 2 to the traveling wheels 3 on the one hand, and drives the cultivating shaft 5 of the rear rotary 4 on the other hand to drive the plurality of cultivating pawls 6 mounted on the cultivating shaft 5. It is a mobile agricultural machine that is mainly rotated to perform light work such as management work.

As shown in FIG. 1, the cultivator 1 has a machine body 8 and a rotary 4 which are integrally formed, and a rear portion of the machine body 8 has a gear shift operation lever 9 for changing a traveling speed and a handle 10.
, Are arranged so as to extend diagonally rearward.

As shown in FIG. 1, the handle 12 is fixed to the fuselage 8 by a single pipe 8a.
It is divided into two right and left pipe-shaped handles 10 at an intermediate portion, and its base is rotatably fixed around a rotation shaft 8b in several stages, and the grip portion 11 of the handle 10 is adjusted according to the posture of the operator. The height is adjustable.

As shown in FIG. 2, the grip portion 11 has a grip 12 formed at the rear end portion of the handle 10 having a pipe structure with a soft material such as synthetic rubber or synthetic resin rubber.
It is constructed by covering the upper part with a comfortable touch, which makes it easy to operate.

Immediately before the left side grip portion 11, as shown in FIG. 3, an inverted L-shaped fixed substrate 1 is provided on the outer surface of the handle 10.
4 is welded, and on the other hand, a fixed cover 16 having an inverted U-shaped cross section and having a switch button 15 formed of synthetic resin sandwiched in advance is covered from above the fixed substrate 14 and the handle 10.

The switch button 15 has a push button section 15
a and the main body portion 15b, and as described above, the fixed cover 1
6 is inserted from above, and the lower main body portion 15b is fixed with a nut 18 so as to sandwich the upper surface of the fixed cover 16, while the wiring 19 connected to the stop mechanism of the front engine 2 is provided.
Is connected to the contact portion 15c at the bottom of the main body 15b through the hole of the fixed substrate 14, the fixed cover 16 is covered from above the fixed substrate 14 and the handle 10, and the main body 15b is covered as shown in FIG. It is housed in the space formed by the fixed substrate 14 and the fixed cover 16, and is fixed by fastening the boss 16 a provided in front of and behind the fixed cover 16 from the lower side to the fixed substrate 14 with the fastening member 20.

The wiring 19 is connected to the stop mechanism of the engine 2 in the front, and the switch button 15 is used during an emergency during operation.
By pressing the push button portion 15a with a finger through the wiring 19, the operator can stop the rotation of the engine 2 through the wiring 19 while holding the grip portion 11.

INDUSTRIAL APPLICABILITY The present invention relates to a mobile agricultural machine which transmits power from an engine to a traveling section and a cultivating section and operates a handle extending to the rear of the machine while traveling and cultivating work, in the vicinity of the control section of the handle. A switch cover that is disposed and that stops the engine by its operation; a switch-mounted mounting cover that covers the upper portion of the handle; and a fixed substrate that is fixed to the handle. Since the fixed cover is covered with the mounting cover from above the handle, and the mounting cover is fixed from below, the worker can move forward while holding the control section during an emergency during operation. The engine can now be stopped without moving.
