DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for winding a hose and a method for discharging a liquid according to an embodiment of the present invention will be described with reference to the drawings. 1 to 5, reference numeral 1 denotes a liquid discharging device that discharges water or a liquid containing a drug to agricultural land or the like. The liquid discharging device 1 guides a liquid that is pumped by a pump (not shown). A hose 2, a liquid discharge portion (for example, a nozzle having a liquid discharge port) 3 located at a tip end of the hose 2,
And a winding unit 4 for winding the hose 2 (see FIG. 1).

As shown in FIGS. 2 and 3, the winding section 4
One of a hose reel 5 for winding up the rotatably supported hose 2, a motor 6 for rotating the hose reel 5 at a constant rotation speed, and one of the hose reels 5 Hoses with rotation
The hose 5 has a hose alignment portion 7 that moves in the axial direction of the hose 5 by the outer diameter of the hose 2.

The rotation transmission of the motor 6 for rotating the hose reel 5 at a constant rotation speed is, for example, as shown in FIG.
Sequentially, motor 6, joint 8, gear 9, pulley 11, belt 1
0, pulley 11 ', hose reel shaft 12, and hose reel 5 are transmitted. Note that an electromagnetic clutch may be used instead of the pulley 11.

For example, when the load applied to the motor 6 exceeds a certain value, the joint 8 cuts off the rotation transmission between the motor 6 and the hose reel 5 and causes the hose reel 5 to rotate. Stop the rotation,
The winding operation of the hose 2 is stopped. Specifically, it is a product name of Permatorque (registered trademark) manufactured by Koshin Seikosho Co., Ltd., which is composed of two magnets and one disk. The disk is fixed to a shaft and is held by a bearing.

When the disk rotates, countless lines of magnetic force between the two magnets act to hinder the rotation of the disk. This resistance varies depending on the relative positions of the magnetic poles of the magnet, and when the torque exceeds a certain value. The magnetic poles of the magnets facing each other have the same polarity and repel each other so that rotation transmission is interrupted.

The gear 9 is for reducing the rotation of the motor 6. A take-up member reel 13 is provided alongside the pulley 11 '. This winding member reel 13 is a reel for winding a winding member 14 such as a string, a piano wire, a wire, etc., having a diameter smaller than the diameter of the hose 2. The diameter is
The diameter of the hose reel 5 is substantially the same.

In the middle of the hose 2 (more specifically,
As shown in FIGS. 1, 2, 4 and 5, the swivel hose part 2 which has swirled the hose 2 is located at a position close to the liquid discharge part 3.
a is provided.

Reference numeral 20 denotes a swivel hose part 2 which has swung the hose 2.
a is a cover that covers a.
A hose tip side opening 20a located at the tip side [liquid discharge portion (for example, a nozzle having a liquid discharge port) 3] of the hose;
And a hole-side opening 20c located on the side of the reel 5. The hose 2 of the revolving hose portion 2a located at the hose reel side opening 20c is locked by a member 2b. Reference numeral 2c denotes a connecting tool for connecting the hoses 2 to each other.

Therefore, the hose 2 on the opposite side of the liquid discharge section 3
The liquid discharge section 3 is moved from the position of the winding section 4 to a working position far from the position of the take-up section 4 while a tip portion of the pump is placed in a tank containing water or a liquid containing a chemical, not shown, and a pump not shown. To guide the liquid pressure-fed by the pump through the hose 2, and a liquid discharging portion (e.g., a nozzle having a liquid discharging port) provided at the tip end of the hose 2.
3. The liquid is discharged by 3 (see FIG. 1).

The discharging operation of the liquid is performed along the direction approaching the winding unit 4, and the hose reel 5 of the winding unit 4 rotates slowly and winds up the hose 2. Then, the hose aligning unit 7 moves the hose reel 5 in the axial direction by the outer diameter of the hose 2 with one rotation of the hose reel 5. The hose aligning section 7 is, for example, the same as the hose aligning and winding device (24) described in JP-A-7-215597.

Then, as the winding of the hose 2 onto the hose reel 5 proceeds, the winding speed of the hose 2 increases, but the turning hose portion 2a is released from the turning state. By being pulled out from the hose cover 20 (see FIGS. 4 and 5), it is possible to prevent a load from being applied to the tip side of the hose 2 and to cause the hose 2 to pull the worker. Ease of work can be eliminated.

In particular, if the turning hose portion 2a is installed at the work site without the hose cover 20 and the turning hose portion 2a is exposed, the turning hose portion 2a is set in an extended state. In such a case, there is no point in providing the turning hose portion 2a. By providing the hose cover 20, the swiveling hose portion 2a can be reliably installed at the work site in a coil state.

When the hose 2 is taken up, for example, the revolving hose portion 2a is extended, and the hose 2 is wound around the hose reel 5 so that the hose 2 is wound. The winding speed of the hose 2 is increased, and a load is applied to the tip of the hose 2.
In this case, the worker is pulled by the work 2 and the work becomes difficult. In order to avoid this, when the load applied to the motor 6 exceeds a certain value, the joint 8 connecting the rotating shaft of the motor 6 and the gear 9 is disconnected, and the motor 2 and the hose sleeve are disconnected. The transmission of rotation with the knob 5 is interrupted.

As shown in FIGS. 4 and 5, a mark, for example, a red tape 30 is intermittently affixed to the hose 2 (including the turning hose portion 2a). When winding the reel 2, it is possible to quickly confirm whether the hose 2 is moving or not by looking at the mark 30.

Further, the host cover shown in FIGS.
Instead of 20, a hose cover 20 shown in FIGS. 6 to 10 may be used. This hose scubaber 20 is formed by rotating the hose 2 around a revolving hose winding shaft 22 urged by a band spring 21, that is, covering the revolving hose portion 2a therein. is there. 2d is a return joint, and 2e is a stopper member. And as shown in FIG. 6 and FIG.
Is connected to the liquid discharging section 3 and the stopper member 2e is connected to the winding section 4 side. Hoosukaba 20 is the attachment string 20b
Can be worn by workers.

In this embodiment, as in the above-described embodiment, the winding speed of the hose 2 increases as the winding of the hose 2 onto the hose reel 5 progresses. E
By releasing the swiveling state of the hose portion 2a and pulling it out of the hose scuba 20 (see FIGS. 9 and 10), a load is prevented from being applied to the front end side of the hose 2 and the hose 2 is prevented. S2
Can eliminate the difficulty in working due to pulling the worker.

In the above-described embodiment, an operator is required to discharge the liquid. However, in the following embodiment, the operator can be omitted and automation can be achieved.

As shown in FIG. 11 (FIGS. 2 and 3), the liquid discharging section 3 is mounted on a movable carriage 50,
The winding member 14 such as a string, a piano wire, a wire, or the like having a diameter smaller than the diameter is connected to the carriage 50. Then, the take-up member 14 is taken up by the take-up member reel 13 which is rotated by the motor 6, and the liquid discharge section 3 is gradually approached to the take-up section 4.

The winding speed of the hose 2 increases as the winding of the hose 2 onto the hose reel 5 proceeds, but the turning hose portion 2a is released from the turning state. By being pulled out of the hose cover 20 (see FIGS. 4 and 5), the load is prevented from being applied to the tip end of the hose 2 and the bogie 50 is moved by the winding member 14 at a substantially constant speed. Thus, a substantially constant liquid can be automatically discharged from the end of the hose 2.

[0028]

According to the hose winding method of the first aspect, the winding speed of the hose increases as the winding of the hose onto the hose reel proceeds. By the simple means of the hose cover which covers the swiveling hose part,
When the turning hose portion is released from the turning state and is pulled out of the hose scubaber, it is possible to prevent a load from being applied to the tip of the hose and to cause the hose to pull the worker. Ease of work can be eliminated.

According to the method of winding a hose described in the second aspect, in addition to the effect of the first aspect described above,
When the hose is taken up, for example, if the load on the motor exceeds a certain value in a state where the revolving hose has been pulled out from the hose cover, the motor and the hosel are removed. In order to stop the rotation of the hose reel and stop the winding operation of the hose by interrupting the rotation transmission with the hose, no load is applied to the tip of the hose, Can eliminate the difficulty in working due to pulling the worker.

According to the liquid discharging method of the third aspect, as the winding of the hose around the hose reel progresses,
Although the winding speed of the hose increases, the load is prevented from being applied to the bogie by the turning hose part being released from the turning state and being pulled out of the hose cover, and the winding member is used. At a substantially constant speed, the carriage can automatically discharge a substantially constant liquid from the end of the hose.
