などの課題を有していた。In FIG. 5, the water flowing in the water supply pipe 21 is cleaned of dirt and foreign substances by the filter 23, and the liquid fertilizer in the liquid fertilizer tank 25 is adjusted in advance by the liquid fertilizer mixing device 22 to set a mixing ratio. Is mixed in. The flow rate is adjusted by the flow rate adjusting valve 24. In addition,
At the time of constantly irrigating water only, the mixing ratio of the liquid fertilizer in the liquid fertilizer mixing device 22 is set to 0, the suction strainer 26 is removed from the liquid fertilizer tank 25, or as shown in FIG.
The valves 27 and 28 are closed and the valve 29 provided in the bypass pipe 30 is opened to prevent liquid fertilizer from being mixed. In this equipment, since water flows through the liquid fertilizer mixing device 22 even when only water is constantly supplied, the flow-through capacity of the liquid fertilizer mixing device 22 must be sufficiently large, and a failure or the like is likely to occur. If 22 is removed for maintenance, etc., it will not be possible to perform watering with only regular water.

And a liquid fertilizer proportional mixing device in the middle of the bypass pipe.

The through hole is communicated with the pipe to minimize the flow resistance, and the orifice hole is communicated with the pipe to maximize the fluid resistance. In this case, the orifice hole provided in the ball is preferably a hole on the inflow side and a hole having a size substantially equal to the valve size on the outflow side.

通って水だけが送水される。Since the present invention is configured as described above, when water is supplied to the water supply pipe, a differential pressure is generated between the upstream side and the downstream side of the water supply pipe due to the action of the flow resistance device, and the water passing through the bypass pipe is Create a flow. Due to this flow of water, liquid fertilizer is mixed into water at a mixing ratio preset and set in the liquid fertilizer proportional mixing device arranged in the middle of the bypass pipe. It should be noted that the ratio of the flow rate flowing through the flow resistance device to the flow rate flowing through the bypass pipe is constant according to the flow resistance in these flow paths, so that it flows through the water supply pipe of the liquid fertilizer mixed in the bypass pipe. The mixing ratio with respect to the total flow rate is also constant. Next, when the bypass pipe is closed by the stop valve, water does not flow in the bypass pipe, so that the mixing of the liquid fertilizer in the liquid fertilizer proportional mixing device is stopped and only the water is sent through the flow resistance device.

検、手入れや交換が容易にできる。Since the liquid fertilizer proportional mixing device is installed not in the water supply pipe through which the total amount of water is supplied but in the bypass pipe with a small flow rate, it may have a small flow-through capacity, and it can be used only for water used for a relatively long time. Since water does not flow during water supply, it is unlikely that a malfunction will occur. Further, by disposing the stop valves at both ends of the bypass pipe and closing them, the inspection, maintenance and replacement of the liquid fertilizer proportional mixing device can be easily performed.

ト高になったり、配管が複雑になったりする。As a flow resistance device, an orifice structure is simple and convenient. However, in the case of a fixed orifice, when only water that does not mix liquid fertilizer is supplied, pressure loss occurs due to the flow resistance of the orifice, and the flow rate decreases. Moreover, in general, the time for sending water alone is much longer than the time for injecting liquid fertilizer and sending water. For this reason, it is necessary to increase the water supply pressure of the pump and to separately provide a water supply bypass pipe parallel to the orifice, which results in high cost and complicated pipe.

Can be made. Further, when the through hole is communicated with the pipe, the size of the through hole is almost equal to the size of the valve and hence the size of the water supply pipe, so that flow resistance can be minimized and only water can be sent. Moreover, since this flow resistance device has a ball valve structure, it is extremely easy to switch between the water supply of water only and the water supply of liquid fertilizer-mixed water.

Is similar in size to the through hole 3e, and therefore has a size substantially equal to the size of the water supply pipe 5. Therefore, the flow resistance is minimum in the state of FIG. 3 in which the through hole 3e is communicated with the water supply pipe 5,
In the state of FIG. 4 in which the orifice hole 3f is connected to the water supply pipe 5, the flow resistance is maximum.

水される。Next, the operation will be described based on the embodiment shown in FIGS. The water that has flowed through the water supply pipe 5 is filtered by a filter 10 to remove dirt and foreign matter. Due to the action of the flow rate resistance device 2 or 3, a pressure difference is generated between the upstream side and the downstream side, and a flow of water through the bypass pipe 6 is generated. Due to this flow of water, the liquid fertilizer in the liquid fertilizer proportional mixer 4 is sucked into the liquid fertilizer in the liquid fertilizer tank 7 at a preset mixing ratio and mixed into the water. In addition, the flow rate flowing through the flow resistance device 2 or 3 and the bypass pipe 6
Since the ratio of the flow rate of the liquid fertilizer and the flow rate of the liquid fertilizer mixed therein is constant according to the flow resistance in these flow paths, the mixing ratio of the liquid fertilizer mixed in the bypass pipe 6 to the total flow rate of the water supply pipe 5 is also constant. Next, when either or both of the shutoff valves 8 and 9 are closed in the bypass pipe 6, water does not flow in the bypass pipe 6, so that the mixing of the liquid fertilizer in the liquid fertilizer proportional mixer 4 is stopped, and the flow resistance device 2 or 3 is connected. Only water is sent through.

Water does not flow when only water is supplied,
It is difficult for troubles to occur. Further, it is easy to inspect, clean and replace the liquid fertilizer proportional mixing device 4 by closing both the stop valves 8 and 9 arranged at both ends of the bypass pipe 6.
