[Prior Art]

 Conventionally, in Japanese Utility Model Laid-Open No. 2-34454, a self-propelled sprinkler truck is provided on a laid rail, and a sprinkler pipe is provided on the sprinkler truck, and a hose is connected to the sprinkler pipe. There has been proposed a sprinkler used in a house or the like, which sprinkles water supplied from a sprinkler pipe. In such a sprinkler, the sprinkler truck travels by pulling the hose, so the running motor of the sprinkler must be made large. Therefore, there was a problem that the sprinkler became large. As a solution to such a problem, for example, as shown in Japanese Utility Model Application Laid-Open No. 59-162559, it is conceivable to mount a hose winder that rotatably supports a drum on the watering cart.

[0003]

[Problems to be solved by the device]

 When the hose winder is attached to the watering truck, the hose wound on the drum can be unwound as the watering truck travels, but the hose cannot be automatically wound. There was a problem. As one means for solving such a problem, it is conceivable to provide the drum with a motor via an electric clutch, but the electric clutch is relatively expensive, which may increase the cost of the apparatus.

An object of the present invention is to solve the above problems and to provide a sprinkler device that can automatically wind up a hose by a motor equipped with a general-purpose speed reducer without using an electric clutch. ..

[Action]

 In the water sprinkler according to claim 1, when the hose in which the water sprinkler body travels in one direction is fed, the cam rotated in one direction by the motor via the drive side transmission member rotates faster than the rotation of the driven side ratchet. However, the driven ratchet becomes free, and the hose is extended as the sprinkler body runs. On the other hand, when the sprinkler body travels in the other direction, the cam engages with the driven ratchet and the drum can be rotated to wind the hose.

In the sprinkler according to the second aspect of the present invention, when the hose in which the sprinkler body travels in one direction is fed, the torque of the motor is not transmitted to the drum by the one-way clutch, while the sprinkler body moves in the other side direction. When winding a hose that travels to, the torque of the motor is transmitted to the drum by the one-way clutch and the hose can be wound.

【Example】

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings. The sprinkler main body 3 that moves along a pair of left and right rails 2 laid in the vinyl house 1 has a sprinkler pipe 7 supported on an upper portion of a trolley main body 6 having a built-in forward / reverse motor 5 that drives wheels 4. It is provided so as to project to the left and right through the pipe 7A. One end of a supply pipe 8 is connected to the center of the sprinkling pipe 7, and water supplied from the supply pipe 8 can be sprinkled downward from a nozzle 8A provided in the supply pipe 8. There is. The hose take-up device 9 has a bogie main body 10 provided behind the bogie main body 6 via a connecting portion 11. Wheels 12 running on the rail 2 are rotatably provided on the lower four sides of the carriage body 10. A shaft 15 of a drum 14 for winding up the hose 13 is rotatably provided on an upper portion of the bogie main body 10 via a bearing 17 on columns 16 standing upright on both sides. The drum 14 is provided with flange portions 19 on both sides of the cylindrical portion 18, and the peripheral surface of the cylindrical portion 18 is provided toward the rail 2. Further, a hollow portion 15A is formed from the other side of the shaft 15 to substantially the center of the cylindrical portion 18, and a rising short pipe 15C penetrating the cylindrical portion 18 is provided at one end 15B of the hollow portion 15A. The base end of the hose 13 is connected to the pipe 15C, and the supply pipe 8 is connected to the tip 15B. Further, a drive side sprocket 20 as a drive side transmission member is provided on one side of the shaft 15 so as to be freely rotatable. The drive side sprocket 20 and a drive side sprocket 22 which is a drive side transmission member provided on a motor 21 and provided with a speed reducer (not shown) and rotatable in one direction (arrow A) and the other direction (arrow B). A chain 23, which is a suspension member, is suspended on the. Therefore, the drive side sprocket 20 can also rotate in one direction (arrow A ') and the other direction (arrow B'). Further, a driven ratchet 24 is provided on the shaft 15 inside the driving sprocket 20. The driven ratchet 24 is rotatably provided on a tubular portion 26 of a bracket 25 rotatably provided on the shaft 15, and a flange portion 27 of the bracket 25 is fixed to the flange portion 19. .. Friction members 28 and 29 are provided on the left and right of the driven ratchet 24. One friction member 28 is interposed between the flange portion 27 and the driven ratchet 24, and the other friction member 29 is pressed against the driven ratchet 24 by a bullet 30. Incidentally, 31 is a fixing plate for locking the other side of the bullet 30. Further, on the side surface of the drive side sprocket 20, a horizontal rotary shaft 32 is provided so as to be rotatable toward the driven side ratchet 24. A cam 33 that can be locked to the driven ratchet 24 is fixed to the tip of the rotary shaft 32. Incidentally, the cam 33 is always brought into contact with the tooth portion 24A on the rotary shaft 32 by an ammunition 32A such as a winding spring. Further, an electric wire 34 is integrally provided along the hose 13 with an adhesive tape or the like. An extension 34A of the electric wire 34 is connected to an electrode 35 provided on the other side of the shaft 15, and a control device (not shown) for controlling the motors 5 and 21 via a brush 36 to the electrode 35. Lead wire 37 of is connected. 38 is a metal fitting for fixing the brush. Incidentally, 2A and 2B are convex portions provided at the end of the rail 2, and 5A and 5B are limit switches for stopping.

Next, the operation of the above configuration will be described. Set the watering cart 3 and the hose winding device 9 on the rail 2, connect the tip of the hose 13 to the water supply source P such as water supply or pump, and connect the electric wire 33 to the power source Q manually or by a timer. The switch is turned on at a preset time (not shown). For this reason, the motor 5 is operated via the electrode 35 and the brush 36, the wheels 4 rotate, the sprinkler cart 3 moves forward, and water is sprinkled from the nozzle 8A toward the nursery box R. At the same time, the carriage main body 10 of the hose winding device 9 is also pulled and moved forward, and the drum 14 rotates in the one direction (arrow a) and the hose 13 is paid out. At this time, the angular velocity V (rad / min) of the drive side sprocket 20 in the arrow A'direction by the motor 21 rotating in the arrow A direction is integrated through the drum 14 rotating in the arrow a direction and the friction members 28, 29. Since the angular velocity v (rad / min) of the tooth portion 24A of the driven ratchet 24 rotating in the direction of the arrow a'is set in advance (V> v), the cam 33 is always toothed on the driven ratchet 24. Along the portion 24A, it idles without being locked to the tooth portion 24A. The angular velocity v at the time of feeding is determined by the forward speed of the watering truck 3 and the diameter of the driven ratchet 24. Therefore, the drum 14 can rotate in the direction of arrow a in the free state to feed the hose 13. At this time, electric power is supplied from the electric wire 34 to the control device of the motor 5 and the motor 21 via the extension 34A, the electrode 35, the brush 36, and the lead wire 37. In this way, when the watering truck 3 travels while watering to the end of the rail 2, when the forward stop limit switch 5A comes into contact with the convex portion 2A provided at the tip of the rail 2, the limit switch 5A is moved. The motor 5 and the motor 21 are reversed and, for this purpose, the motor 5 and the motor 21 are reversed via a control device (not shown) mounted on the watering truck 3, and the motor 5 causes the watering truck 3 to move backward. At the same time, the motor 21 rotates in the direction of arrow B, and therefore the cam 33 engages with the tooth portion 24A of the driven ratchet 24, so that the rotational force of the motor 21 rotates in the direction of arrow B on the driving side sprocket 22. , The drive side sprocket 20 is rotated in the direction of the arrow B'through the chain 23. Further, this rotational force is transmitted to the drum 14 through the engagement between the rotary shaft 32, the cam 33 and the tooth portion 24A of the driven side ratchet 24, and the friction members 28 and 29, and as a result, the drum 14 is rotated. Wind the hose 13 by rotating it in the direction of arrow b. In this way, the sprinkler truck 3 moves backward while sprinkling water, and the hose 13 is wound around the drum 14. At this time, the angular velocity of the driven ratchet 24 in the direction of arrow b'is slightly larger than the angular velocity of the drum 14 in the direction of arrow b, but this difference is eliminated by the friction between the friction members 28 and 29 and the driven ratchet 24. It When the water truck 3 finishes moving backward, the reverse stop limit switch 5B comes into contact with the convex portion 2B of the rail 2 to stop the power supply to the motor 5 and the motor 21.

As described above, in the above-described embodiment, the drive side sprocket 22 and the drive side sprocket 20 of the motor 21 having the reduction gear are mounted on the carriage main body 10 which is integral with the sprinkling carriage 3 provided with the traveling motor 5. A chain 23 is suspended on the driving side sprocket 20, and a cam 33 is provided on the driving side sprocket 20 via a rotating shaft 32.On the other hand, a driven side ratchet 24 capable of locking the cam 33 on a drum 14 rotatably supported. Is integrally provided, and the angular velocity V of the cam 33 is set to be larger than the angular velocity v of the driven ratchet 24 that accompanies the traveling of the sprinkling carriage 3 at all times. When the drum 14 rotates forward in the direction of the arrow a to feed the hose 13 together with the sprinkling carriage 3, the cam 33 rotates faster than the driven ratchet 24 in the direction of the arrow a ′, and the cam 33 moves to the driven ratchet 24. 3 Since the drum 14 can be set in the free state by not engaging the 3 with each other, the hose 13 can be sequentially delivered as the bogie body 10 advances. When the carriage body 10 is further retracted, the cam 33 is engaged with the ratchet 24 on the driven side to rotate the drum 14 and the hose 13 can be wound up. Therefore, the hose 13 can be delivered and wound using the relatively inexpensive motor 21.

4 and 5 show a second embodiment of the present invention. The same parts as those of the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted. In the second embodiment, the shaft 15 is provided on the tubular portion 26 of the bracket 25 via the one-way clutch 41, and the chain 23 is suspended on the driving side rocket 20. The one-way clutch 41 has a piece-shaped clutch body 44 interposed between the outer ring 42 and the inner ring 43 so that the torque of the outer ring 42 can be transmitted to the inner ring 43 only when the outer ring 42 rotates in the direction of the arrow B '. It has become. The flange portion 19 and the flange portion 27 are slidably provided with each other, and the shaft 15 and the flange portion 19 are fixed to each other.

Therefore, when the sprinkling bogie 3 moves forward, the motor 21 rotates the driving sprocket 22 to rotate the driving sprocket 20, but the torque of the driving sprocket 20 is increased by the one-way clutch 41 to the shaft 15 side. Therefore, the drum 14 is in a free state, and the hose 13 is extended as the watering truck 3 moves forward. On the other hand, when the watering truck 3 moves backward, the motor 21 reversely rotates and the drive side sprocket 22 rotates. Therefore, the drive side sprocket 20 rotates, and this rotation torque is transmitted to the shaft 15 and the drum 14 via the one-way clutch 41, and as a result, the drum 14 rotates and the hose 13 can be wound up.

As described above, the one-way clutch 41 including the outer race 42, the inner race 43, and the clutch body 44 is provided between the drive side sprocket 20 and the shaft 15 so that the rotation torque of the motor 21 is transmitted to the drum 14 only at the time of winding. By doing so, the hose 13 can be wound around the drum 14 when the water truck 3 is retracted by using the relatively inexpensive general-purpose motor 21.

The present invention is not limited to the above-described embodiment. For example, in the first embodiment, a plurality of cams may be integrally provided on the drive side sprocket 20. Various modifications are possible, such as allowing the vehicle to be driven by towing instead of being driven by a motor.
