Yes. At the time of spraying the chemical solution, the support column 13 is turned upright and the liquid feed pipes 2 and 3 are connected in a straight line in the vertical direction, and the total length of the liquid feed pipes 2 and 3 is about 2 to 3 m. Is done.

  Each of these liquid feeding pipes 2 and 3 is provided with a plurality of nozzles 4 and 5 serving as chemical spraying portions at appropriate intervals along the extending direction of each of the liquid feeding pipes 2 and 3. These nozzles 4 and 5 are installed such that their spray ports are directed in the horizontal direction or slightly above horizontal.

  Further, as shown in FIGS. 1 and 3, the blower 6 is mounted on the sprinkler 1 at a position forward of the liquid feeding pipe 2 and below the liquid feeding pipe 2 and the nozzle 4. The blower 6 is installed such that its rotation axis extends in the vertical direction and the air outlet 6a faces upward, and causes an upward air flow from the air outlet 6a.

  Also, an air direction control device 7 that controls the air direction of the upward air flow is installed on the upper side of the blower 6. This wind direction control device 7 has a pair of wind direction plates 7a and 7a arranged so as to face each other in order to guide the upward air flow from the blower 6 upward, and as shown in FIG. And a connecting mechanism 7b capable of adjusting an angle (open angle) formed between the plates 7a and 7a.

  The wind direction plate 7a is a flat plate-like member, and is spaced apart so as to face the vehicle width direction, and the lower side thereof is pivoted with respect to the upper side of the blower 6. The connection mechanism 7b connects one end side of each connection plate 7c to each corner of the upper end of each wind direction plate 7a, and overlaps the other end of the connection plates 7c, 7c connected to the corresponding corners. In addition, the overlapping portions 7d are respectively formed, and one end portion of the connecting rod 7e is pivotally attached to one overlapping portion 7d and the other end side of the connecting rod 7e is pivotally attached to the other overlapping portion 7d. When the connecting rod 7e is pulled upward as indicated by the phantom line, the opening angle that opens upward between the wind direction plates 7a and 7a is reduced as indicated by the phantom line, the upward wind direction is narrowed, and the blowing area is reduced. On the other hand, when the connecting rod 7e is pushed downward as indicated by the solid line, the opening angle between the wind direction plates 7a and 7a is increased as indicated by the solid line, the upward air direction is widened and the blowing area is increased.

  According to such a control machine 100, when the sprayer 1 is traveling in the furrow A of the tomato height cultivation with the liquid feeding pipe 3 standing upright, the chemical liquid is nozzled through the liquid feeding pipes 2 and 3. While being sprayed from both directions 4 and 5 in the vehicle width direction, the blower 6 is driven and an upward air flow is formed above the blower 6. For this reason, the chemicals from the nozzles 4 and 5 are sprayed obliquely upward on both sides in the traveling direction of the spreader 1 by the upward flow by the blower 6 and toward the leaves of the crop on both sides of the furrow A. It is preferably sprayed. Then, the upward flow by the blower 6 reaches the upper part in the furrow A, and the leaves of the crop are swung from the bottom to the top by this upward flow, so that the chemical solution is filled from the upper side to the lower side of the crop to the back of the leaves. Evenly sprayed.

  Here, if it is desired to adjust the wind direction and the air volume of the upward air flow, the wind direction control device 7 may be controlled. For example, if the connecting rod 7e is lowered to increase the opening angle between the wind direction plates 7a, 7a, The chemical can be sprayed to the side.

  Thus, in the present embodiment, the liquid feeding pipes 2 and 3 are provided so as to extend in the vertical direction, the nozzles 4 and 5 are provided at appropriate intervals in the liquid feeding pipes 2 and 3, and the liquid feeding pipe 2 and 3 and the nozzles 4 and 5 below are provided with a simple structure in which a blower 6 that generates an upward air flow is provided, and the chemical sprayed from the nozzles 4 and 5 is moved to a high place by the upward flow of the blower 6. Dispersing evenly and liquid feeding pipes 2 and 3 extending in the vertical direction enable traveling without any trouble in the narrow furrow A. Therefore, it is possible to spread the medicinal solution to a high place while suppressing costs. Can be performed sufficiently. In addition, since the chemical solution adheres to the back of the leaves, the working speed can be increased, which leads to labor saving.

  In the present embodiment, the wind direction control device 7 includes a pair of wind direction plates 7a and 7a for guiding the upward air flow upward, and the opening angle between the wind direction plates 7a and 7a can be adjusted. With the simple structure, there is an advantage that the wind direction of the upward air flow can be controlled.

  FIG. 5 is a perspective view showing another wind direction control device. The difference between the wind direction control device 17 and the previous wind direction control device 7 is that a trumpet-shaped member whose opening increases as it goes upward is divided into two along the axis, and each of them is opposed to the vehicle width direction. It is the point which was spaced apart and used as a pair of wind direction board 17a, 17a. And the angle (open angle) which these wind direction plates 17a and 17a comprise can be adjusted with the connection mechanism 17b substantially the same as the previous connection mechanism 7b. In FIG. 5, a member corresponding to the connecting rod 7e shown in FIG. 3 is not provided, but a connecting rod may of course be present.
