供することを目的としている。However, in the conventional structure described above, the vertical plate-shaped blades rotating around the vertical axis collide with the powder particles that have been dropped and supplied to diffuse the powder particles. The powder particles that collide and scatter here mainly diffuse sequentially in the lateral width direction while repeating collision reflection with respect to the inner wall portion of the guide member. Since the action is performed by a plurality of reflections to the guide member which is the fixed wall, it is difficult to exert a sufficient diffusion action to the outer side in the widthwise direction,
In particular, when the drug is sprayed in a field or the like, there is a drawback that the distribution of the drug spray becomes uneven. As a method of solving the above problem, it is conceivable to increase the diameter of the diffusion rotor to increase the initial diffusion capacity, but in this case, there is a disadvantage that the front-rear width of the device becomes unnecessarily large. is there. It is an object of the present invention to provide a powdery- or granular-material spraying device which has a compact shape and can sufficiently diffuse in the lateral width direction by a rational structure.

幅方向に充分拡散されることになる。Since the diffusion rotor is configured to rotate around the axis along the longitudinal direction of the machine body, it is not necessary to increase the width in the longitudinal direction of the machine even if the diameter thereof is increased in order to enhance the diffusion function. The front-rear width of the machine can be reduced to a small one. Further, since the powder and granular material is diffused by rotating around the front-rear axis, the dispersion discharge power in the lateral width direction is increased by the strong direct collision and scattering action of the diffusion rotor itself, and the fixed part such as the guide member is fixed. It is possible to sufficiently diffuse the granular material in the width direction while minimizing the number of reflections with respect to. Moreover, the diffusion rotor has a simple structure in which a pair of plate bodies are connected to each other by a blade body, but by forming a ventilation hole at least near the center of rotation of one plate body, the diffusion rotor can be formed. When the blades are driven to rotate, the air flows into each plate through the ventilation holes, and the air discharged toward the outer side in the radial direction generated by the blades smoothly flows, so that the powder and granular materials are transferred to the blades. Not only is the bounce-off impact force caused by, but also the air flow to the outside is taken into account and it is sufficiently diffused in the lateral direction of the aircraft.

It has become possible to provide a powdery or granular material spraying device that can sufficiently diffuse the powdery or granular material along it and can make the powdery or granular material diffusion distribution in the lateral direction of the machine body substantially uniform.
