The chemical solution in the chemical tank a passes through the pump b, the pressure regulating valve c, and the three-way tank d, and then is sent to the nozzle (right) by the water divider e.
The flow is divided into f, nozzle (middle) g, and nozzle (left) h and is sprayed, and when the pressure is increased above a predetermined level, it is returned to the chemical tank a from the pressure regulating valve c, and the entire amount is returned by switching the three-way cock d. The spraying amount from each nozzle f, g, h is determined by the pump pressure, so if the spraying amount per unit area is determined, the vehicle speed, The pump pressure and nozzle diameter are determined by comprehensively considering the pump pressure and nozzle diameter. For example, when it is desired to increase the vehicle speed, the pump pressure is increased, the nozzle diameter is increased, or both of these methods are adopted.

As mentioned above, the amount of chemical sprayed from the nozzle is determined by the pump pressure and nozzle diameter, and the vehicle speed is also determined at this time, and the vehicle travels at a constant speed and air volume. In response to the,
If you want to partially increase or decrease the spray amount, you have to manually change the vehicle speed or pump pressure. Furthermore, regarding air volume, if a separate engine is used for the blower, the engine speed can be changed by operating the throttle lever, or if one engine is shared for driving and driving the blower. For those equipped with a transmission between the engine and the blower, the speed ratio is changed and the rotational speed of the blower is changed to adjust the air volume. It was virtually impossible to respond appropriately to the growing conditions of crops within the country.

Spray with a small air volume commensurate with that. At this time, based on the vehicle speed and pressure detected by the vehicle speed sensor 23 and the pressure sensor 13, the microcomputer 29
The first actuator 20 controls the pressure regulating valve 10 assuming that the spray amount is proportional to the square root of the spray pressure. When the vehicle speed is high, naturally the pressure regulation pressure of the pressure regulation valve 10 is increased to increase the amount of spraying. The air volume is adjusted based on the information on the state of growth from the optical sensor 24 and the sonic sensor 25. If there is a lot of vegetation, the transmission 31 is controlled to increase the gear ratio and the rotation speed of the blower 6 to increase the air volume. Increase. In the opposite case, the air volume is lowered, but the air volume is controlled to the extent that the chemical solution adheres to the crops and never reaches zero.
