Then, the support shaft (40) provided on the support plate (40a) projecting upward from the frame (1) in the vicinity of the support piece (23a) has an intermediate sprocket consisting of a pair of sprockets (17a) and (17b).
(17) rotatably supports the free insertion shaft, and the support shaft (4)
A driven sprocket (15) is pivotally supported via a one-way clutch (13) and a needle bearing (13a), and two chains (i.e., between the drive, intermediate, and driven sprocket (2c) (17) (15) are supported. 1
The speed-increasing transmission mechanism and the one-way transmission mechanism are configured so that the speed is increased by winding 6).

Also, a support shaft that is located outside the boss (3a) of the traveling wheel (3).
The rear sprocket (10) is fitted and fixed to the outer periphery of the portion (5), and the bearings (43a) (43a) in the support frames (42a) (42b) respectively connected to the front end portions of the both frames (1) are provided. 43b) includes the support shaft
(4) Both ends of the Napier shaft (12) transverse to the frame (1) are placed so as to be lower than the frame (1) and lower than the frame (1).

The napier shaft (12) is fitted with a sliding body (44) that reciprocates in the axial direction, and is attached to both support shafts (44a) that are hung parallel to the lower side of the sliding body (44). , The reel-shaped guide members (11) for sandwiching and guiding the hose (B) are respectively mounted, and the guide body (45) protruding above the sliding body (44) is attached to the horizontal frame (1a ) Is fitted in the lateral guide groove (46) formed in the rear portion. And
A chain (1) is attached to the front sprocket (47) and the rear sprocket (10) fitted and fixed to the right end of the napier shaft (12).
8) is hung, and the pin (49) is inserted in the diameter direction inside the barrel (48) fitted and fixed to the right end of the Napier shaft (12).
The tip of the crank type manual handle (19) is detachably fitted to the barrel (48), and the pin is attached to the tip.
An engaging groove (50) that can be fitted in the (49) is formed.

Therefore, for example, when the hose (B) on the ground, which is extended from the power sprayer (not shown) and is connected to the winder at a long distance, is wound around the windup drum (9) during the spraying work. The drive wheels as shown in FIGS. 1 and 2.
Set so that (8) is on the front side of the axis (0), and
Use the lever (39a) to cam the long diameter side of the cam (39) in contact with the outer end surface of the support shaft (4) in the direction indicated by the phantom line
Rotate (39) and pull the rod (36) to press the friction plate (14) strongly against the friction plate (4a) via the compression spring (35). When driven, the airframe advances in the direction of arrow (a).

With the forward movement of this aircraft, the traveling wheels (2) (3) that are in contact with the ground rotate, and in particular, the rotation of the traveling wheels (2) is driven by the drive / intermediate sprockets (2c) (17) and chain (16). Via driven sprocket (15)
The speed of rotation is transmitted to the support shaft (4) via the one-way clutch (13) from the support shaft (4) to the friction plates (4a) (14) and the pin (41). ) And is transmitted to the winding drum (9). At the same time, the rear sprocket (19) of the support shaft (5) that rotates together with the winding drum (9) rotates the napier shaft (12) via the chain (18), and both guide members (11) reciprocate laterally. Then, the hose (B) on the ground is neatly wound around the winding drum (9) while being guided by both guide members (11).

In that case, the winding distance of the traveling wheel (2) (3) by one rotation and the winding dimension of the hose (B) by one rotation of the winding drum (9) may be longer or shorter depending on the diameter, and Depending on the length of the hose (B) wound on the take-up drum (9),
Effective diameter changes, hose (B) by one rotation of the drum (9)
There is a difference in the winding size. Therefore, the rotation of the traveling wheel (2) is increased by the speed increasing transmission mechanism and transmitted to the winding drum (9), and the winding drum (9) is moved relative to the traveling distance of the traveling wheel (2).
The initial winding size of the hose (B) is roughly matched by rotating the hose (B) at the same time, and the winding size that gradually increases from the initial stage to the final stage of the hose (B) on the winding drum (9) is adjusted according to the gradually increased size. The hose (B) extended above the ground will be pulled, but this pulling force acts on the friction plate (14) as a resistance to rotate the support shaft (4) with the friction plate (4a). I am correcting by sliding.

In this way, the take-up drum (9) slows its rotation speed according to the resistance, and the hose (B) is forcibly dragged and wound up without damaging the hose, and the length of the hose corresponds to the distance traveled. (B) will be wound up.

On the contrary, when the hose (B) is extended and placed on the ground, the handle (7) remains in the same position and the other drive unit (A) rotates 180 degrees around the axis (0). Then, as shown by the phantom lines in FIGS. 1 and 2, both drive wheels (8) have the axial center (0).
When the aircraft is set so that it is displaced further rearward and the aircraft is moved backward in the direction of the reverse arrow (a), the traveling wheels (2) run in reverse and the winding drum (9) moves toward the hose (B) placed on the ground. By the resistance of), the hose (B) can be paid out by rotating as it is.

At that time, since the speed-up reverse rotation of the sprocket (15) has a fast rotational speed relationship with the rotation rotation of the winding drum (9), that is, the support shaft (4), it is a one-way transmission mechanism. Due to the directional clutch (13), the speed-up reverse rotation of the sprocket (15) is not transmitted to the support shaft (4), and the support shaft (4) is free in the reverse rotation direction in a range slower than the reverse rotation of the sprocket (15). Reverse rotation, that is, the winding drum (9) can rotate.

As described above, the rotation of the traveling wheel (2) and the rotation of the winding drum (9) are synchronized by the rotation tuning device including the speed increasing transmission mechanism, the one-way transmission mechanism, and the slip transmission mechanism.

In that way, since the winding drum (9) is coaxial with both running wheels (2) (3), it is possible to lower the center of gravity of the aircraft and to control it well so that the aircraft does not tip over,
Further, since the napier shaft (12) is arranged at the low position in front of the machine body, the hose (B) can be satisfactorily guided by the guide member (11) at the low position and can be wound up in an orderly manner.

When the hose (B) is wound up without moving the machine body, the detuning device is used and the minor diameter side of the cam (39) is on the outer end surface of the support shaft (4) as shown by the solid line in FIG. Rotate the cam (39) with the lever (39a) so that the friction plate
The elastic force of the compression spring (35) against (14) can be weakened so that the winding drum (9) can be set to rotate freely in the forward and reverse directions regardless of the traveling wheel (2). In that state, fit the tip of the manual handle (19) into the barrel (48) and
Insert the (50) into the pin (49) and rotate the sepia shaft (12) with the manual handle (19) to reciprocally move the guide members (11) in the lateral direction to move the winding drum (9). It will be able to rotate and the hose with the aircraft stopped
You will be able to wind (B) in an orderly manner. It should be noted that, with the same structure, an electric cord or other cord-shaped body can be similarly wound or unwound on the winding drum (9).

Further, the manual handle (19) may be of a power type using a low-speed rotating motor.

[Effects of the Invention] As described above, according to the present invention, it is possible to stably move the airframe forward and backward while changing the direction of the drive unit (A) and rotating the traveling wheels (2) and (3). Take-up drum
By lowering the (9) and the guide body (11), it is possible to reliably and smoothly wind up and unwind the linear body, which is suitable as a winding machine with good stability and operability. It has the features that can.
