There was a throttle lever. This arm is a practical application Sho 58-176750 (actual development Sho 60-84740)
As shown in FIG. 3, the robot is provided so as to be held in the vertical storage posture and the front working posture. However, as for the work posture, the arm is more suitable for the work in the "diagonal front direction" than in the "forward direction".
As shown in (Actual Development Sho 62-28972), the pivots of the base of the arm are "inclined vertically and horizontally, and are provided so as to hold the arm in a retracted posture in a vertical direction and a working posture in an oblique front direction". Since the pivot axis of this arm is "inclined vertically and horizontally", it is tilted in two directions, which makes machining centering, casting, and mold making complicated and complicated. It was Also, since the arm was provided orthogonally to the axis, the arm could not be made exactly vertical,
Even in the vertical storage position, it will be slanted outwards,
It was protruding from the plane and was in the way.

常位置に復帰するよう設けられている。The chemical spraying machine 1 is configured as follows. That is, as shown in FIG. 1 which is an overall side view, a working device 2 (a drug spraying device in this embodiment) is attached to an L-shaped frame-shaped backpack frame 3 made of synthetic resin. That is, the fan case 5 containing the blower fan and the fuel tank 7 are mounted, and the engine 9 is fixed to the rear surface of the fan case 5. A recoil starter 10 having a recoil handle 8 is provided at the rear of the engine 9. A medicine tank 11 is mounted on the upper part of the fan case 5. A blower pipe 15 is connected to the blower opening 13 of the fan case 5. A back support 17 is mounted on the front surface of the vertical portion of the backpack frame 3, and backpack bands 19 that connect the upper and lower ends are provided on both sides. A support body 23 is fixed to the left side surface of the backpack frame 3 by screws 21 and 21, as shown in FIG. 2 when the mounting state (vertical posture) of the arm 27 is viewed from a direction perpendicular to the rotation surface thereof. The support 23 has a mounting surface 25 that is inclined rearward.
(In FIG. 3 which is a plan view, the side surface 3a of the backpack frame 3 intersects at a point P), and one end of the arm 27 is attached to the mounting surface.
It is pressed and held against the mounting surface 25 by a bullet 31 through a pivot 29 that penetrates 25 at right angles. That is, arm 27
Is a rod-shaped member that is substantially straight and is provided orthogonal to the pivot 29 that inclines with respect to the side surface 2a. When storing and transporting the medicine spraying machine 1, as shown in FIGS. However, at the time of work, as shown in FIG. 3, it is rotated to a horizontal position so as to project obliquely to the front side. arm
At the tip of 27, a throttle lever 35 interlocking with a throttle valve (not shown) via a wire 33 is rotatably supported by a bolt 39 via a washer 37, and is supported to such an extent as to be held at the rotating position. ing. Further, a stop button 41 for stopping the engine 9 by short-circuiting the ignition primary circuit is provided on the tip 1 side. A trigger-shaped choke lever 45 pivotally attached to the shaft 43 is provided on the lower surface of the central portion of the arm 27.
It is pivotally attached in the direction of 27 and is provided interlocking with a choke valve (not shown) via a wire 47. By operating in the direction of arrow A in FIG. 2, the choke valve is closed. When the fuel concentration increases and the hand is released, it is rotated by the ammunition machine 49 in the direction opposite to the arrow A, and the choke valve is returned to the normal position in the open state.

When the arm 27 is rotated in the B direction to have the horizontal work posture shown in FIG. 3, the arm 27 is in the diagonally forward direction. Throttle lever
Hold the 35 in the operating position suitable for starting and
The 45 is pulled against the ammunition 49 in the direction A in FIG. 3, and the starter handle 8 of the recoil starter 10 is pulled to start the engine 9. At the same time, when the choke lever 45 is released, the engine 9 maintains the idle state. In working, when the worker puts the backrest 17 on the back and hangs the backpack band 19 on both shoulders and carries the backpack frame 3, the arm 27 projects diagonally forward to the left of the worker, and the blower pipe 13 is located on the right side. Will be done. The operator holds the blower pipe 13 with the right hand and appropriately operates the throttle lever 35 with the left hand.
