It is preferable to provide a controller (not shown) for displaying the state and the opening degree, and to perform this by remote control from this controller.

  In addition, the above-mentioned controller, a storage unit that stores an appropriate opening degree of the openings 3A, 3B corresponding to the type of material and the target mixing ratio, an input unit that inputs the type and mixing ratio of the material, and an input Based on the material type data and the mixture ratio data thus obtained, the opening degree stored in the storage section is taken out, and the opening section 3A, 3B is controlled to drive the driving section so as to reach the target opening degree. And a part (not shown).

  According to such a spraying device A, different types of materials (for example, fertilizers) are stored in the storage spaces 1A and 1B, respectively, and the opening / closing device is used so that these materials can be sprayed as a mixed material having an intended mixing ratio. 4A and 4B can be operated to adjust the opening degree of the openings 3A and 3B.

  For example, put nitrogen (N) in the storage space 1A and a mixed material of phosphoric acid (P) and potassium (K) in the storage space 1B, and open the opening 3A in a place where nitrogen (N) is insufficient in the same field. It is possible to make fine adjustments such as increasing the temperature to increase the amount of nitrogen (N) and reducing the opening of the opening 3A to decrease the amount of nitrogen (N) in an excessive place.

  In this case, the opening degree of the opening 3A can be adjusted based on the growth map of the field and the data of the sensor that determines the growth in real time.

  Further, when the growth data of the sensor for judging the growth is used, it is possible to control the growth data obtained in real time to be reflected in the automatic opening adjustment of the openings 3A and 3B by the control unit.

  After the openings of the openings 3A and 3B are set, the materials can be supplied from the storage spaces 1A and 1B to the sub hopper 2B in an amount that provides a target mixing ratio.

  The materials supplied to the sub hopper 2B are mixed by the swing of the sub hopper 2B to become a mixed material having an intended mixing ratio, and this mixed material can be sprayed from the spout 2C swinging integrally with the sub hopper 2B.

  That is, the spraying device A stores different kinds of materials in the storage spaces 1A and 1B, and adjusts the openings of the openings 3A and 3B to adjust the amount of the materials supplied to the sub hopper 2B. The amount can be made to a ratio of the mixed materials.

  Therefore, even when a situation occurs in which a mixed material having a different mixing ratio is sprayed onto other crops or soil during the spraying work, the mixing ratio can be changed by adjusting the openings of the openings 3A and 3B. Therefore, the efficiency of the spraying work can be improved.

  Further, by closing one side of the openings 3A, 3B, it is possible to spray a single material.
