DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine which is rotated by the rotational force of a wheel while a spray operator runs an airframe between ridges when spraying a chemical solution on a field crop using a power sprayer. The present invention relates to a traveling-type hose winder configured to automatically wind a spray hose around a take-up drum.

[0002]

2. Description of the Related Art When a chemical spray is sprayed on crops in a field using a power sprayer, the spray hose is unwound from a winding drum, or the wound spray hose is re-wound onto a winding drum. Winding is essential. A hose automatic winding device configured to automatically wind a spray hose by rotating a winding drum with power is used in part, but this is expensive, and in a small-scale farmhouse, from a profitable point of view. You may not be able to purchase. When this hose automatic winding device is not used, the winding of the spray hose must be manually performed. For example, as shown in FIG. 9, when using a spraying work vehicle D having a structure in which a spray pipe 53 is attached to a front part of a body 52 having wheels 51, the spraying work vehicle reaches the end of the ridge G. D travels to unwind the spray hose H wound on the winding drum 54 placed on a truck bed or the like, and performs a spraying operation when returning to the power sprayer S side as indicated by an arrow P. However, it is necessary to wind up the spray hose H by an operator different from the operator pulling the spraying vehicle D.

[0003]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides a spray hose by rotating a winding drum using a driving force of a wheel obtained by an operator moving an airframe. An object of the present invention is to automatically sprinkle a chemical solution by automatically winding the same so that only one worker can spray the chemical solution efficiently.

[0004]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention is directed to a method in which a winding drum is rotated by a rotating force of a wheel mounted on an airframe traveling in a ridge of a field, and is connected to a power sprayer. A traveling-type hose winder for winding a spray hose, wherein a winding drum is rotatably supported on the body, and between a wheel axle and a driving wheel mounted on the same.
Alternatively, a torque adjuster capable of adjusting the transmission torque is interposed between the winding shaft of the winding drum and a driven vehicle mounted on the winding shaft, so that the driving force can be transmitted from the driving vehicle to the driven vehicle. It is characterized in that a clutch is interposed in a driving force transmission path for transmitting the rotational force of the wheels to the winding shaft of the winding drum.

[0005] In the case of performing the spraying operation when the aircraft retreats,
First, the operator moves the machine forward between the ridges by closing the clutch mechanism so that the driving force is not transmitted to the winding shaft. In this state, since the driving force is not transmitted to the winding shaft, the winding drum rotates freely, and a predetermined tension acts on the spray hose as the body advances, whereby the spray hose is unwound from the winding drum. The spraying of the medicinal solution on the crop is performed while the clutch mechanism is operated and the machine body is retracted from the end of the ridge. In this state, the rotational force of the wheels is transmitted to the winding shaft, so that the winding drum can rotate. Here, the speed at which the winding drum winds the spray hose is designed to be always higher than the traveling speed of the aircraft, and if the torque adjuster is not interposed in the above-described portion, the winding is performed. Although the drum part becomes overloaded and cannot be wound, the excess rotation of the winding drum, which increases in accordance with the increase in the diameter of the hose, is slipped by the torque adjuster part (the driving wheel attached to the axle, Alternatively, one of the driven wheels attached to the winding shaft slips and rotates), so that a predetermined tension is applied to the spray hose, and the spray hose is driven at the same speed as the running speed of the machine. It is wound up. In the initial stage of winding, if the spray hose is slackened and no tension acts on it, the winding speed of the spray hose with respect to the winding drum is:
Although the speed is temporarily higher than the running speed of the airframe, after the tension is applied to the spray hose, an excessive rotation occurs in the winding drum, and the excessive rotation is slipped at the torque regulator.

5 shows a spill hose for returning the excess chemical liquid supplied to the tank 4 to the chemical liquid tank 4.

First, the configuration of the fuselage A will be described.
As shown in FIGS. 1 to 3, a pair of wheels 5 is disposed below the body A on both sides thereof, and these wheels 5 are mounted on both ends of the axle 6. The axle 6 is horizontally arranged along a direction perpendicular to the traveling direction of the fuselage A, and is supported by two bearings 7 arranged on the bottom surface of the frame 1. As shown in FIG. 5, a torque adjuster T is attached to an outer peripheral portion of one side of the axle 6 near the wheel 5, and the torque adjuster T is attached to the axle 6.
, The lower pulley 9 is attached.

Next, the winding drum 12 for the machine body A
Will be described. As shown in FIGS. 2 and 3, a support frame 11 is attached to the upper surface of the frame 1. As shown in FIG. 3, the rod portions 11 a on both sides of the support frame 11 are disposed upright when viewed from the front of the body A, and the winding shaft 1 of the winding drum 12 is provided above them.
3 is rotatably mounted. An upper pulley 14 is attached at a position corresponding to the lower pulley 9 of the winding shaft 13, and a belt 15 is mounted on each of the upper and lower pulleys 9, 14. The belt 15 is attached in a loosened state so that tension is not generated in a normal state.
The clutch mechanism C has a configuration in which a tension is generated by pressing a tension roller 16 described below against the belt 15. In a state where tension is generated in the belt 15,
The driving force obtained by the rotation of the pair of wheels 5 becomes the driving force for rotating the winding drum 12 from the torque adjuster T attached to the axle 6 via the upper and lower pulleys 9 and 14 to form a winding. It is transmitted to the take-up shaft 13.

Next, the configuration of the clutch mechanism C will be described. As shown in FIGS. 2 to 4, a bracket 17 is provided on the rod portion 11 a on one side of the support frame 11.
It is mounted perpendicular to the axle 6 and vertically. A fulcrum rod 18 is provided on the bracket 17 so as to protrude outside the body A. The fulcrum rod 18 has a lever 1
9 is rotatably mounted. A support rod 21 is provided at the tip of the lever 19 so as to protrude inside the body A, and the tension roller 16 is rotatably attached to the support rod 21. The lever 19 is provided with a plurality of mounting holes 22, and a hook 23 a at the tip of a compression spring 23 is mounted in one of the mounting holes 22. The rear end of the compression spring 23 is connected to a wire 25 at a block 24.
Is fixed to the bracket 17. This wire 25
Is connected to an operation lever 26 attached to the driving handle 3. By operating the operation lever 26, the wire 25 is pulled, and the lever 19 is moved to the fulcrum rod 18
Around the center. The situation where the lever 19 rotates at that time is shown by a two-dot chain line and a solid line in FIG. As a result, the tension roller 16 is pressed against the belt 15 and the belt 1
Tension occurs in 5. The tension roller 16 is the belt 1
The force of pressing 5 can be adjusted by changing the mounting hole 22 of the lever 19 to which the hook 23a of the compression spring 23 is mounted.

Next, the configuration of the torque regulator T will be described. As shown in FIG. 5, a hub 28 having a flange 28a is attached to the axle 6 via a key 27.
The lower pulley 9 is fitted into the main body 28 b of the hub 28 via a slide bearing 29, and is attached with both sides sandwiched between the friction plates 8. Further, an adjustment nut 31 is screwed and attached to the main body 28b of the hub 28. Between the nut 31 and the friction plate 8 disposed on the opposite side of the flange 28a of the hub 28, A disc spring 32 is interposed. By tightening the adjustment nut 31, both side surfaces of the lower pulley 9 are pressed against the friction plates 8. By this pressing force, the outer side surface of the lower pulley 9 and each friction plate 8
A frictional force is generated between the lower side pulley 9 and the upper side pulley 14 via the belt 15 to rotate the winding shaft 13 of the winding drum 12. By rotating the adjustment nut 31 to adjust the amount of compression of the disc spring 32, the driving force transmitted to the winding shaft 13 can be adjusted.

As shown in FIG. 6, a bracket 33 is mounted on the driving handle 3 so as to be supported by both rod portions 3a. At a substantially central portion of the bracket 33, a fulcrum rod 34
The center portion of the alignment lever 35 is rotatably attached to the fulcrum rod 34. The lower end of the alignment lever 35 is a ring-shaped hose guide 35a.
The spray hose H is slidably inserted into the hose guide portion 35a. In a state where the spray hose H is wound on the winding drum 12, the operator turns the alignment lever 35 alternately left and right so that the spray hose H is aligned with the winding drum 12 over the entire width thereof. Rolled up.

Then, as shown in FIGS. 7 and 8,
In order to spray a chemical solution on crops using the hose winder B according to the present invention in which the spray tube 2 is attached to the tip of the machine body A, first, an operator pushes the machine body A between the ridges to terminate the ridge G at the end. The spraying operation is performed when the body A is moved backward in the direction of arrow P from the end of the ridge G. Aircraft A
When the vehicle is moved forward, the operation lever 26 attached to the driving handle 3 is released. Then, since tension is not applied to the belt 15, even if the pair of wheels 5 rotates, the belt 15 idles, and no driving force is transmitted to the upper pulley 14. However, since one end of the spray hose H is connected to the power sprayer S, a predetermined tension acts on the spray hose H by moving the machine body A forward, and the winding drum 12 is rotated by this tension. And spray hose H
Is unwound. When the fuselage A is advanced to the end of the ridge G in this state, the spray hose H continuously unwound from the winding drum 12 crawls between the ridges.

As shown by a dashed line in FIG.
Is advanced to the end of the ridge G, the valve 36 disposed below the spray pipe 2 is opened, the chemical is sprayed from the spray pipe 2, and the operation lever 26 attached to the operation handle 3 is operated. The aircraft A is moved backward in the direction of the arrow P in the state in which the vehicle is in the retracted state. By operating the operation lever 26, tension is generated in the belt 15. Therefore, the driving force of the pair of wheels 5 is controlled by the belt 15 and the upper and lower pulleys 9 and 14.
, And is transmitted to the winding shaft 13 as a driving force for rotating the winding drum 12. That is, the winding drum 12 rotates at the same time as the body A retreats.

Here, in the hose winder B according to the present invention, the spray hose H is completely wound around the winding drum 12 by making the outer diameter of the upper pulley 14 smaller than the outer diameter of the lower pulley 9. Even in a state where the take-up drum 12 is not taken up (that is, a state where the take-up speed of the take-up drum 12 is the lowest),
2 is designed so that the winding speed of the spray hose H is higher than the traveling speed of the machine body A. For this reason, when the torque adjuster T is not interposed in the above-described portion, the winding drum 12 tries to wind the spray hose H at a speed higher than the traveling speed of the machine body A. The portion 12 becomes overloaded, and the winding of the spray hose H becomes impossible. However, in the present invention, since the torque adjuster T is interposed in the above-described portion, the spray hose H
Excessive rotation of the winding drum 12 is slip-rotated in the torque regulator T except for the initial winding period in which no tension acts on the spray hose H, so that a predetermined tension is applied to the spray hose H. The spray hose H is wound around the winding drum 12 at the same speed as the traveling speed of the machine body A. However,
At the initial stage of winding, as shown by a chain line in FIG.
When the spray hose H is slackened and no tension is applied, the spray hose H is temporarily wound around the winding drum 12 at a winding speed higher than the traveling speed of the aircraft A, After the spray hose H is completely slackened and the tension is applied to the spray hose H, an excessive rotation occurs in the winding drum 12, and the excessive rotation is slip-rotated at the torque regulator T. When the fuselage A is retracted in this way, the spray hose H is smoothly wound on the winding drum 12 attached thereto with a predetermined tension F, as shown by the solid line in FIG. Note that the torque adjuster T
When the set torque is too small for the winding of the spray hose H, the load that can be borne is reduced (the transmission torque is reduced), and the winding drum 12 rotates even when the body A retreats. If it is not possible to wind the spray hose H and the set torque is too large for the winding of the spray hose H, the load that the torque regulator T can bear becomes excessive (transmission torque). Becomes excessively large), and when the torque required for the rotation of the take-up drum 12 at the initial stage of take-up is the smallest, the axle 6 and the lower pulley 9 rotate integrally, and slip rotation does not occur at this portion. , The rotation of the wheels 5 becomes impossible. Therefore, it is necessary to set the torque of the torque regulator T to an optimum value that does not cause any of the above-described phenomena.

In this embodiment, the torque adjuster T is interposed between the axle 6 on which the pair of wheels 5 is mounted and the lower pulley 9 mounted thereon. Even if the torque adjuster T is interposed between the winding shaft 13 and the upper pulley 14 mounted on the winding shaft 13, the excessive rotation of the winding drum 12 can be slipped. If a clutch mechanism is provided in the driving force transmission path from the axle 6 to the winding shaft 13, a chain gear is mounted on each of the axle 6 and the winding shaft 13, and a chain is mounted on each chain gear. Alternatively, a configuration may be adopted in which a driving force is transmitted from the axle 6 to the winding shaft 13 by attaching a gear to each of the axle 6 and the winding shaft 13 and directly meshing each gear.

[0017]

The hose winder according to the present invention is provided between a wheel axle and a drive wheel mounted on the wheel axle, or between a winding shaft of a winding drum and a driven wheel mounted on the same. In either case, a torque adjuster capable of adjusting the transmission torque is interposed, so that the driving force can be transmitted from the driving vehicle to the driven vehicle. Excessive rotation of the take-up drum is slipped at the torque regulator, and the spray hose is wound around the take-up drum at a speed substantially equal to the running speed of the machine body under a predetermined tension. Therefore, only the worker pushing or towing the machine can automatically take up the spray hose without power, and perform the spraying operation of the chemical solution on the crop.
