For example, since the flow of the fertilizer and the herbicide differs in the spray boom 6, the position of the collision plate 60 is automatically adjusted so that the spray area is adjusted to an appropriate area. An appropriate position for each application agent of the collision plate 60 is set in advance, and this application agent is determined under the detection of the collision plate position sensor 64, and the motor 61 is driven by the output from the controller 40. The collision plate 60 is adjusted and controlled to an appropriate position according to the spray application agent (FIG. 8). When the set application rate is less than a certain value, it is determined as a herbicide, the collision plate drive motor 61 is turned on, the collision plate position sensor 64 is read, and when the set value (K1) is reached, the motor 61 output is turned off.

  In FIG. 9, the collision plate 60 is provided so that the position of the collision plate can be changed and adjusted by manual operation. After reading the collision plate position adjustment dial 65 and setting the collision plate position (K), the collision plate drive motor 61 is turned on. When the value of the collision plate position sensor 64 reaches the set value, the motor 61 output is turned off. To do. While checking the spraying state, the position of the collision plate 60 is set appropriately to improve the spraying performance.

  In FIG. 10, the collision plate 60 is driven by a motor 61. However, when this is changed by manual operation, the position of the collision plate 60 can be stored in the memory 50 of the controller 40. . The position data of the collision plate 60 set according to the collision plate position adjustment dial 65 is written and stored in the nonvolatile memory 50 when the collision plate 60 setting input is turned on. The collision plate position can be made appropriate while checking the spraying state, and by storing the value, the value can be used at the time of the next spraying work, and the adjustment is reduced again.

  Furthermore, the position of the collision plate 60 can be changed and set according to the set application amount and specific gravity by the setting switch 32 (FIG. 11). The set application rate and specific gravity are read to determine the position data of the collision plate 60 and the motor 61 is turned on. When the value of the collision plate position sensor 64 becomes the position data, the output of the motor 61 is turned off. The set application amount and specific gravity can be automatically set to an appropriate position of the collision plate 60, improving the operability and improving the distribution performance at the time of spraying.
