) is provided so as to be able to rotate around the support shaft (37) in contact with the outer end surface of the shaft (37), thereby forming a tuning release switching device.

The side plate (2) of the running wheel (2) that forms the outer periphery of the boss (2a)
At the end opposite to h), there is a drive sprocket (2
A pair of sprockets (1
An intermediate sprocket (17) consisting of 7a) and 7b (17b) is rotatably loosely supported, and a driven sprocket is attached to the support shaft (4) via a one-way clutch (13) and a needle bearing (13a). (15), and these driving, intermediate and driven sprockets (2c) (17) (1
5) A speed-increasing transmission mechanism and a one-way transmission mechanism are configured to increase speed by winding two chinos (16) between them.

Further, on the outer periphery of the support shaft (5) of the other side plate (9b) of the winding drum (9), a rear sprocket) (
10) are fitted and fixed, and the support shafts (4) and (5 ), and both ends of a navigation shaft (12) in the transverse direction to the frame (1) are mounted on the frame (1) so as to be at a lower position than the frame (1).

The navigation shaft (12) is fitted with a sliding body (44) that reciprocates in the axial direction. , reel-shaped guide members (11) that clamp and guide the hose (B) are respectively mounted on shafts, and a guide member (
45) is fitted into a lateral guide groove (46) formed at the rear of the lateral frame (la'). A chain (18) is attached to the front sprocket (47) and the rear sprocket (10) which are fitted and fixed to the right end of the navigation shaft (12), and a chain (18) is attached to the right end of the navigation shaft (12). A bottle (49) is inserted in the diametrical direction inside the tube metal (48) that is fitted and fixed to the crank-type manual handle (19).
) is removably fitted into the cylindrical metal (48), and an engagement groove (50) that can be fitted into the bottle (49) is formed in the tip.

Further, although not shown in the drawings, the running wheels (2) may be configured to be able to be driven forward and backward through the transmission from the engine (6) of the drive unit on the side thrust male side, and the horizontal frame of the auxiliary wheel structure may be For attachment that rotates in the left-right direction, an arm may be provided, and a spray nozzle body (not shown) may be removably attached to the arm.

Therefore, for example, during a spraying operation, when a hose (B) on the ground, which is extended from a power sprayer (not shown) and is connected to a remote winder, is wound onto the winder drum (9). To do this, set both axles (8) so that they are forward of the axis (0) as shown in Figures 1 and 2, and then move the cam (39) in the direction shown by the imaginary line in Figure 3. The lever (
The cam (39) is rotated by the rod (39a).
6), the friction plate (
14) is strongly pressed against the friction plate (4a), when both axles (8) are driven, the aircraft moves forward in the direction of arrow (A).

As this aircraft moves forward, the running wheels (2) are in contact with the ground,
The auxiliary wheel (3) rotates, especially the rotation of the running wheel (2),
Drive/intermediate sprocket (2c) (17), Cheno (1)
6), the speed is increased and transmitted to the driven sprocket (15), and this accelerated rotation is transmitted to the one-way clutch (13).
from the support shaft (4) to the skewer plate (4) through the support shaft (4).
a) (14), the winding drum (9) via the pin (41)
) will be communicated to. The rear sprocket (10) of the support shaft (5) rotates simultaneously with the winding drum (9)
rotates the napier shaft (12) via the chain (18), causing both guide members (11) to reciprocate laterally, so that the hose (B) on the ground rotates through both guide members (11).
It is wound up on the winding drum (9) in an orderly manner while being guided by the winding drum (9).

In that case, the distance traveled by one rotation of the running wheel (2) and the winding dimension of the hose (B) by one rotation of the winding drum (9) will vary depending on their diameters, and
The effective diameter changes depending on the length of the hose (B) wound around the winding drum (9), and a difference occurs in the winding dimension of the hose (B) by one revolution of the drum (9).
Therefore, the rotation of the running wheel (2) is increased in speed by a speed-up transmission mechanism and transmitted to the winding drum (9), and the winding drum (9) is rotated at an increased speed for the traveling distance of the running wheel (2). By doing so, the initial winding dimensions of the hose (B) are approximately equalized, and the winding dimension of the hose (B), which gradually increases from the beginning to the end of the winding drum (9), is adjusted to the ground according to the gradually increasing dimension. The extended hose (B) will be pulled, but this pulling force will act as resistance on the friction plate (14), and the rotation of the support shaft (4) will be made to slide between it and the friction plate (4a). , has been corrected.

In this way, the rotation speed of the winding drum (9) is reduced according to the resistance, and the hose (B) can be stretched to a length corresponding to the distance traveled without being forced to drag the hose (B) while winding it up and causing damage. Winding (B) will be performed.

Conversely, when the hose (B) is fed out and placed on the ground, the handle (7) remains in the same position and the other drive unit (A) is rotated 180 degrees around the axis (0). Then, both axles (
8) is deviated rearward from the axis (0),
When the aircraft moves backward in the direction of the reverse arrow (a), the running wheels (2)
runs in the reverse direction, and the winding drum (9) is able to rotate on its own axis due to the resistance of the hose (B) placed on the ground and pay out the hose (B).

At this time, since the accelerated reverse rotation of the sprocket (15) has a faster rotational speed than the rotation of the take-up drum (9), that is, the support shaft (4), the one-way transmission mechanism is The sprocket (
The accelerated reverse rotation of the sprocket (15) is not transmitted to the support shaft (4), and the support shaft (4) freely rotates reversely in the reverse rotation direction within a range slower than the reverse rotation of the sprocket (15). 9) becomes able to rotate.

As mentioned above, the rotation of the running wheel (2) and the winding drum (
The rotation in 9) is synchronized by a rotation synchronization device consisting of a speed-up transmission mechanism, a one-way transmission mechanism, and a sliding transmission mechanism.

Furthermore, since the take-up drum (9) is coaxial with the running wheels (2), the center of gravity of the machine can be lowered. Since it is configured to be supported by (3), it is possible to control the aircraft well so that it does not fall over, and it is possible to run by straddling the soft ground, making it possible to run stably without damaging the planted plants. , navigation axis (12
) is arranged at a low position in the front of the machine, the hose (It) can be well guided by the low-positioned guide member (ll), and can be wound up in an orderly manner.

In addition, when winding up the hose (B) without moving the machine, use the synchronization release device so that the short diameter side of the cam (39) is aligned with the outer end surface of the support shaft (4) as shown by the solid line in Figure 3. The cam (39) is rotated by the lever D9a) so that the cam (39) contacts the friction plate (14), and the elastic force of the compression spring (35) is weakened so that the winding drum (9) rotates in the forward and reverse direction. ) can be set to rotate freely regardless of the

In this state, attach the tip of the manual handle (19) to the tube metal (48).
) and at the same time, insert the engagement groove (50) into the pin (49).
into the Napier shaft (1) using the manual handle (19).
2), the winding drum (9) can be rotated while reciprocating both guide members (11) in the lateral direction, and the hose (9) can be rotated while the machine is stopped.
B) can be wound by hand in an orderly manner.

Further, the manual handle (19) may be powered by a motor that rotates at a low speed.

In addition, in the case of the drive structure on the side thrust male side, the drive part is not reversed, and the engine power is switched between forward, neutral, and reverse by the mission, but in the case of forward and backward drive, the output sprocket and cheno are controlled by the transmission. , through the running wheels (
2) will be transmitted to the inlet block block which is integrally fixed to the inlet block.

[Effects of the Invention] As described above, the present invention makes it possible to stably move the aircraft forward and backward while rotating the running wheels (2) by operating the drive unit (^), and furthermore, the winding drum ( 9)
By lowering the guide body (11>), the linear object can be reliably and smoothly wound up and unwound, and the auxiliary frame can be slid in the left and right directions according to the dimensions of the soft material. The auxiliary wheels can be easily adjusted to a soft position, and the machine body does not tend to fall over, making it suitable for use as a winding machine with good stability and operability.
