Description

[Detailed description of the invention] This invention is applied to a relatively small hose winding drum used for irrigation work such as crop seedling management, and is an automatic hose reeling and winding device that is remotely controlled by a radio control device. Regarding.

Currently, watering work such as raising seedlings is done by a person holding the water nozzle at the end of the hose, and a person holding the water nozzle at the end of the hose and winding the hose. At least two people are required, including a person who will be near the drum and pay out and wind up the hose. In other words, in the case of a manual type, when you move forward holding the water spray nozzle, the hose is automatically unwound from the hose winding drum, but at this time, the hose winding drum idles due to inertia, and the hose unwinds excessively. This causes problems such as disturbances, so in order to prevent this and to wind up the hose, a person is required to rotate the hose winding drum. Even in the case of a mechanical type, the hose winding drum must be rotated by a signal from the person holding the end of the hose for safety and work accuracy reasons, so there is no need for a person to operate the hose winding drum. is necessary.

This invention enables the person holding the tip of the hose to automatically unwind and rewind the hose by remote control using a radio-controlled device, instead of the irrigation work that currently requires two or more people. The purpose of this invention is to provide a labor-saving device that allows one person to carry out irrigation work.

Examples will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a known hose winding drum (hereinafter abbreviated as the winding drum), which is horizontally suspended rotatably via bearings 3, 3 installed oppositely on an underframe 2.

Pin 7 is attached to the vertically movable arm 4, 4 and the bracket 8, 8 The distal ends of the vertically movable arms 4, 4 are pivotally connected to the support column 5 so as to be vertically movable. Bearings 9, 9 are fixed to the tips of the vertically movable arms 4, 4, and are arranged in parallel along the rotating direction of the winding drum 1. 10,11
and 12 are a hose feed upper roll, a hose feed lower roll, and a hose winding drum drive roll (hereinafter abbreviated as winding drum drive roll), respectively.
The hose winding drum 1 is horizontally mounted on the above-mentioned bearings 9, 9 sequentially from above to below in a parallel and rotatable manner, and the gap between the upper hose feed roll 10 and the lower hose feed roll 11 is used for winding. drum 1
The hose 13 that has been wound and pulled out is clamped and passed through the winding drum drive roll 12.
Hose 1 whose underside is wound around the winding drum
3. Flanges a are provided around both ends of each roll, and are provided to prevent the hose 13 from coming off from each roll. Furthermore, the friction with the hose 13 may be increased by carving a large number of lines on the outer circumferential surface of each of the rolls or applying a process such as pasting a friction material. Further, the hose 13 maintains its outer shape even when water is not being passed through it, and when passing through the gap between the upper hose feed roll 10 and the lower hose feed roll 11, it comes into contact with the rolls with appropriate elasticity. A rubber hose is suitable.

Next, reference numeral 14 denotes a motor, which is installed on the upper surface of the seat plate 6 which is horizontally fixed to the vertical movable arms 4, 4, and can freely rotate forward and reverse and stop via a radio control device, as will be described later. . 15 is a power transmission mechanism interlocking with the motor 14, and the one shown in the figure includes a chain sprocket 16 fixed to the rotating shaft of the motor;

The upper feeding roll 10 and the winding drum driving roll 12 are configured to rotate in the same direction, and the lower hose feeding roll 11 is rotated in the opposite direction at a constant speed.

In the embodiment, since the outer diameters of the rolls are the same, the number of teeth of the chain sprockets 17, 18 and 19 are the same. Further, the power transmission mechanism 15 is not limited to the illustrated winding transmission mechanism, but a gear transmission mechanism may also be used on the condition that each roll is rotated at a constant speed as described above.

Next, referring also to FIG. 3, the radio control device for remotely controlling the rotation of the motor 14 has a receiver 21 and a motor servo 22 fixedly installed on the upper surface of the seat plate 6, and these are connected to the support 5. The motor 14 is connected to a power source 24 through a switch 23 fixed to the transmitter 25, and is configured so that the motor 14 rotates forward and backward and stops in response to radio waves from a transmitter 25. In the figure, 26 is an electric wire connecting the power supply 24 and the switch 23, 27 is an electric wire connecting the switch 23 and the motor servo 22,
28 is an electric wire connecting the motor servo 22 and the motor 14; 29 is the receiver 21 and the motor servo 22;
It is an electric wire that connects the In other words, the current from the power source 24 flows through the wire 26, the switch 23, and the wire 2.
7. The motor 14 is rotated via the motor servo 22 and the electric wire 28, but the receiver 21 is connected to the transmitter 2.
A known forward/reverse rotation switching and stop switch (not shown) installed in the motor servo 22 is actuated via the electric wire 29 by the signal radio wave from 5, and the motor 14 rotates forward/reverse and stops. It is configured as follows.

The above-mentioned radio control device is for one channel, and corresponds to tilting the states lever (not shown) of the transmitter 25 to the left or right and positioning it in the neutral position, and rotates the motor 14 in forward and reverse directions and stops it. For example, if you tilt the states lever to the left, the motor 14 will rotate in the direction of arrow A in Figure 1 (forward rotation), and if you tilt it to the right, it will rotate in the opposite direction (reverse rotation). The servo 22 is activated. In addition, radio control devices are equipped with low-power citizen radio waves (13, 27, and 40 MHz in Japan) that can be used without permission.
Use.

In addition, 30 in the figure is a hose joint, which is a known type that can supply water to the hose 13 even when the winding drum 1 is rotating, 31 is a hose joint that prevents rotation,
32 is a water supply hose, 33 is a water discharge nozzle, and 34 is a water discharge nozzle.

Next, the operation of the device of the present invention will be explained. first,
After pulling out the hose 13 wound around the winding drum 1 and inserting its tip through the gap between the hose feed upper roll 10 and the hose feed lower roll 11, the water nozzle 33 is attached to the part, and the winding drum is driven. The lower surface of the roll 12 is brought into contact with the outer periphery of the hose 13 wound around the winding drum 1. At this time, since the motor 14, the receiver 21, and the motor servo 22 are provided on the upper surface of the seat plate 6, these serve as a heavy load and the winding drum drive roll 12 is brought into pressure contact with the hose 13. On the other hand, the state lever of the receiver 25 is kept in the neutral position, and the switch 23 is turned on so that current flows from the power supply 24 to the motor 14. Then, the operator closes the water discharge nozzle kettle 34, connects the water supply hose 32 to a suitable pump or water faucet, and supplies pressurized water to the hose 13 via the hose joint 30. Next, the worker holds the water spray nozzle 33, carries the transmitter 25 appropriately, and tilts the state lever to the left. Then, the upper hose feed roll 10 and the lower hose feed roll 11 rotate in the directions of arrows B and C in FIG. 1, respectively, and the winding drum drive roll 12 rotates in the direction of arrow D. Due to these rotations, the hose 13 is pinched by the upper hose feed roll 10 and the lower hose feed roll 11 and is unwound, and the winding drum drive roll 12 moves the hose 13 wound around the winding drum 1. Through pressure contact with 13,
The winding drum 1 is rotated in the direction of arrow E. Since the circumferential speeds of the respective rolls described above are configured to be equal, the hose 1 that is fed out by the upper hose feed roll 10 and the lower hose feed roll 11 is
3 and the speed at which the winding drum driving roll 12 rotates the winding drum 1 and sends out the hose 13 from the winding drum 1 are always synchronized. Therefore, since the winding drum 1 does not idle due to inertia as the hose 13 is fed out, the hose 13 is fed out without any disturbance.

When the operator holds the water spray nozzle 33 and advances to a predetermined position according to the above-mentioned method of feeding out the hose 13, the worker operates the transmitter 25 to stop the rotation of the motor 14, thereby stopping the feeding out of the hose 13. .
Then, the water spray nozzle pot 34 is opened to sprinkle water. To wind up the hose 13 after irrigation is complete, close the water nozzle tip 34 to stop the water spray, tilt the states lever of the transmitter 25 to the right, and the motor 1
4 rotates in the opposite direction to the direction of the arrow A in FIG. Each rotates, and the hose 13 is automatically wound around the winding drum 1 while being drawn in. Therefore, the operator only has to hold the water nozzle 34 and return to the winding drum 1 in accordance with the winding speed. At this time, as in the case of feeding, the rotating speed of the winding drum 1 and the hose retraction speed by the hose feed upper roll 10 and the hose feed lower roll 11 are synchronized, so that the hose 13
It is rolled up by Saiichi without any slack.
When the hose 13 is at a predetermined position, the transmitter 25 is operated to stop the motor 14, and the winding of the hose 13 is automatically stopped.

In addition, the transmitter 25 is powered by eight AA batteries.
If there are no obstacles, the radio wave transmission distance is said to be about 1,000 meters, which is sufficient for the hose length used for normal irrigation work.

As is clear from the above explanation, the present invention enables the person doing direct irrigation to perform the irrigation work that conventionally required a person to do the irrigation directly with the water nozzle and a person to operate the winding drum. By simply operating the transmitter on the control device, the hose can be fed out and retracted at will, allowing one person to do the work, which not only saves labor, but also improves safety and work efficiency. It has a big effect.
