DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional side view of a hopper 1 capable of storing powders and granules. At the front of the hopper 1, a flow-down port 3 through which the powder can flow down is opened, and a spray nozzle 4 through which the powder can be sprayed is detachably provided to the flow-down port 3. .
At the rear of the hopper 1, a hand 5 is fixedly provided.

A rod 7 urged rearward by a spring mechanism 6 at the rear of the hopper 1 is supported in the hopper 1 so as to be movable back and forth. A freely provided conical opening valve 8 is supported so as to be able to move back and forth, and a rear end thereof penetrates a rear wall surface of the hopper and projects rearward, and a push button 9 is fixedly provided.

The on-off valve 8 has a conical body 8a formed in a conical shape.
And a guide wing 8b for positioning the cone 8a at the center of the downflow port 3, and the cone 8a being pulled rearward by the urging of the rod 7 makes the circular downflow port 3 by the conical surface. In addition to the complete blockage, the degree of opening of the downflow port 3 can be finely adjusted by relaxing the urging of the rod 7.

At the rear of the hopper 1, there is provided an adjusting mechanism 10 comprising a male screw 10a provided rearward and an adjusting ring 10b screwed into the male screw 10a so as to be adjustable in the front and rear direction. A spring mechanism 6 penetrates the center of the adjusting mechanism 10 and is provided on the adjusting mechanism 10.
Is pushed to the rear by the bias of
Are fixedly provided. In order to ensure that the adjusting ring 10b is screwed into the male screw 10a, a packing 10c may be attached to the tip of the male screw 10.

When the push button 9 at the rear end of the rod 7 is pushed against the bias of the spring mechanism 6, the on-off valve 8 supported at the front end via the rod 7 is pushed, and the conical body 8a is The conical surface opens apart and the powder in the hopper 1 can flow freely. However, the movement of the push button 9 is stopped by hitting the adjusting ring 10b of the adjusting mechanism 10 described above, so that if the adjusting ring 10b is rotated at a predetermined speed and positioned in advance, the flow-down amount of the granular material is optionally controlled. Will be.

The spray nozzle 4 detachably provided at the flow outlet 3 at the front end of the hopper 1 comprises an upper lid 4a and a bottom plate 4b, and a suitable number of projecting spray pins 4c are provided on the bottom plate 4b. . The spray pin 4c guides the powder flowing down from the flow-down port 3 to the opening of the spray pin 4c while dispersing the powder and granular material. The side surface is formed in an arc shape (which may be a circle or an ellipse) and an acute angle or an obtuse angle or an arc shape having a larger curvature than the main body.

[0015]

Since the present invention is constructed as described above, it is possible to push the push button while holding the carrying hand, and there is an effect that the particles can be sprayed very easily.

Further, according to the present invention, the downflow opening can be completely opened and closed by the conical surface of the conical body, so that the amount of the downflow can be finely adjusted without accidental downflow of the powder or granule, and it is convenient. Has a significant effect.

Further, according to the present invention, since the flow rate of the granular material can be adjusted in advance, there is an effect that the granular material can be appropriately and reliably sprayed.

Further, according to the present invention, since there is no accumulation of powder particles on the spray pins in the spray nozzle, there is an effect that the spray can be smoothly and uniformly sprayed.
