DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of distributing a powder or the like, for example, a drug, which is fed out of a storage portion by a feed-out mechanism and dropped and supplied, by a diffusion rotor having scattering blades and driven to rotate. TECHNICAL FIELD The present invention relates to a powder-particle dispersing device configured to be diffused in a direction and scattered and dropped.

[0002]

2. Description of the Related Art Conventionally, in the above-mentioned powdery and granular material dispersing apparatus, as disclosed in, for example, Japanese Patent Application Laid-Open No. 2-138511, a disk that is rotationally driven around a vertical axis is used as the diffusion rotor. A plurality of diffusion blades are erected on the upper side of the disk, and the disk is rotated at a high speed by an electric motor. There has been a configuration in which a frame-shaped guide member that is long in the width direction and that is open downward is provided so as to cover the outer side of the diffusion rotor.

[0003]

However, in the case of the above-mentioned conventional structure, a vertical plate-shaped blade rotating around the vertical axis collides against the powdery material supplied in a falling state and diffuses. Here, the powder particles colliding and scattered are diffused sequentially in the width direction while repeating collision reflection mainly on the inner surface wall portion of the guide member. Since the action is performed by multiple reflections on the guide member, which is a fixed wall, it is difficult to exert a sufficient diffusion action to the outer side in the width direction,
In particular, when a medicine is sprayed in a field or the like, there is a disadvantage that the distribution of the medicine spray becomes uneven. As a method of solving the above problem, it is conceivable to increase the initial diffusion capacity by increasing the diameter of the diffusion rotor, but in this case, there is a disadvantage that the front-rear width of the device becomes unnecessarily large. is there. SUMMARY OF THE INVENTION An object of the present invention is to provide a powdery and granular material dispersing apparatus which can be sufficiently diffused in a lateral width direction with a reasonable structure and with a high dispersing accuracy, while having a compact shape.

[0004]

In doing so, it has a ventilation hole in the rotation shaft core,
A plurality of flying blades are provided near the outer periphery
It is good to consist of the thing.

[0005]

Since the diffusion rotor rotates around the axis along the longitudinal direction of the fuselage, there is no need to increase the width in the longitudinal direction of the device even if the diameter is increased to enhance the diffusion function. The longitudinal width of the fuselage can be reduced to a small value. In addition, since the powder is diffused by rotation about the front and rear axes, the dispersion discharge power in the width direction is increased due to the strong direct collision and scattering action of the diffusion rotor itself, and the fixing member such as a guide member is fixed. It is possible to sufficiently diffuse the granular material in the lateral width direction while minimizing the number of reflections to the particles. And, as the diffusion rotor, powder
The scattering direction of the particles should be
The disc body that regulates and guides in the radial direction is the axis of the flying blade body.
The structure is provided on both sides in the core direction. Therefore, the powder
The scattering direction of the granules is regulated by the width of both discs in the axial direction.
To avoid unrestricted spread in the axial direction
Become so. In other words, the diffusion of the granular material in the axial direction is generated.
In other words, within the spraying range of the granular material in the aircraft lateral width direction,
The width of the diffusion range in the longitudinal direction of the fuselage
Because it becomes different as it gets wider near the axis,
Although it becomes difficult to perform uniform spraying in the aircraft width direction,
In the present invention, as described above, the disk body prevents diffusion in the axial direction.
Suppressed and guided in the radial direction, the powder in the width direction of the aircraft
Efficiently suppresses the generation of uneven dispersion of particles and distributes them evenly
It becomes easy. Further, according to claim 2, the rotating shaft
With a vent in the core, near the outer periphery away from the rotation axis
A diffusion rotor is provided with a plurality of scattering blades.
When configured, the radial direction from the rotation shaft core of the diffusion rotor
Smooth the flow of the rotating wind for good scattering of powder
Easy to do. In addition to this, multiple flying blades
The powder and particles that are scattered by the upper wing
Separately, without being scattered by the upper blade
The fallen powder particles are caused by the scattering blades located below.
Powder, because it gives you the opportunity to
It is easy for the scattering of the particles to be continuous rather than intermittent. One
In other words, the powder material dropped and supplied from above is
If they are scattered all at once, they will give an intermittent scattering action.
Wings, but the wings located outside the rotation axis
Hanedashi divided several times by roots body, and, if the rotational axis side
Flow the smooth wind going radially outward from the
It is easy to obtain a better and uniform spraying state.

[0006]

Thus, while being able to be formed in a compact shape in the longitudinal direction of the fuselage by rational structural improvement , diffusion in the longitudinal direction of the fuselage is suppressed,
The diffusion of the particulate material along the body width direction so sufficiently performed, the machine body transverse
By making the diffusion distribution of powder in the width direction almost uniform,
Improve the spraying accuracy of granules in both spraying range and uniform spraying
The present invention has been able to provide a powdery and granular material spraying device that can be used.
In addition, by adopting the configuration described in claim 2, the diffusion
Storm condition of the data and the splashing by multiple scattering blades
Powders that are easy to spray evenly with good action
A spraying device can be obtained.
