Description

[Detailed description of the invention] [Industrial application field] The present invention is a powder and granular agent that is suitably used in agriculture for spraying or sowing powdered fertilizers and pesticides while being carried by people. The present invention relates to a spray amount adjusting tool, and particularly to an agricultural powder and granular agent spray amount adjusting tool that has excellent practical operability and can easily adjust the spray amount at hand.

[Conventional technology and its problems]

Conventionally, in the technical field of agriculture in Japan, manual scattering of powder and powder agents has been widely practiced. Spraying methods vary depending on the scale of the target, but for example, by holding a container containing powder and granules in your hand, letting the powder flow out from the bottom of the container, and continuously guiding it into the guide pipe, A method of walking spraying from the tip of a tube has been adopted in small-scale agriculture.

Even when spraying the same type of powder and granular agents, the amount of powder and granules sprayed in this way can be finely adjusted depending on the target of spraying, the type of crop, and other various conditions. required. Such adjustment of the amount of spraying is impractical if it has a complicated structure, and although it is desirable to have a simple structure and good operability, no one has been found that is practically satisfactory. Also, if the amount of spraying is relatively small,
Generally, control points tend to get clogged, and each time that happens, it is necessary to tap or shake the control points.

Therefore, the purpose of the present invention is to have a simple structure,
It is an object of the present invention to provide a powder and granular agent dispersion amount adjusting tool that is easy to manufacture and operate and does not have the above-mentioned disadvantages.

[Means for solving problems]

Regarding the powder and granular agent sprayer that achieves the above-mentioned purpose, the inventor of the present invention has developed a highly practical spraying amount adjustment device after making various prototypes and conducting repeated experiments, especially regarding the spraying amount adjustment section. developed.

That is, the present invention is a cylindrical body for adjusting the amount of spraying, which is attached to a sprayer for carrying and dispersing agricultural powder and granules housed in a container, and inside the cylindrical body, a circular shape is provided at an eccentric position. A partition wall having a through hole is integrally formed, and a disk having substantially the same diameter as the circular partition wall and capable of rotating around the center of the circular partition wall is pivotally attached to one surface of the partition wall in surface contact with the partition wall. The disc has a substantially radial missing length from a circle that is the same as the diameter of the through-hole to a relatively small circle over approximately half the circumference along a position corresponding to the eccentric position of the through-hole in the partition wall. An elongated through hole is formed in which the diameter changes continuously, and the disc is integrally connected to a ring attached to the outer peripheral surface of the cylindrical body and rotated by a connecting member, and the ring of the cylindrical body is attached to the ring. An agricultural powder and granule agent application amount adjusting tool is provided in which a through hole is formed over approximately half the circumference of the connecting member for guiding the connecting member in the circumferential direction during rotation of the ring.

The adjusting device of the present invention is particularly suitable for row sowing and streak sowing in field crops, and can also be used very conveniently for hand control of the spray amount, such as accurately spraying a predetermined amount of pesticide for each seedling nursery box. be. However, its structural feature is that a partition wall with a circular through hole formed at an eccentric position is integrally provided almost in the center of the cylindrical body. By assembling disks having round-shaped through holes in a surface-contact manner and rotating a rotation operation ring attached to the outer circumferential surface of the cylinder, the communication area of the left and right sides of the partition wall can be made continuous. The main advantage is that the spraying amount can be easily adjusted to the desired amount by changing the spray amount.

〔Example〕

Next, the adjusting device of the present invention will be explained in more detail with reference to the accompanying drawings.

Fig. 1 is a partially cutaway perspective view of an example of the adjusting device for dispersing powder and granular agents of the present invention, and Fig. 2 is a perspective view showing the rotary operation ring shifted. It is meant to be moved. Also,

In the figure, the cylindrical body constituting the adjuster main body is
A cylindrical part 1 that is equipped with a spray amount adjustment mechanism, and a cylindrical part 1' that is slightly thicker in diameter and equipped with an engaging member for attaching to, detaching from, and fixing to a pipe at the lower outlet of a container containing a powder or granular agent. A circular partition wall 2 is formed integrally with the cylindrical part 1 at approximately the center of the inside of the cylindrical body to separate the inside of the cylindrical body. A circular through hole 3 that does not include a center point is formed. A disk 4 having substantially the same diameter as the circular partition wall 2 is arranged on the surface of the partition wall 2 on the side of the cylindrical portion 1' in surface contact,
It is rotatably attached by a shaft 6 attached to the center of the partition wall 2 . The disc 4 has a zigzag-shaped through hole whose missing length in the radial direction changes continuously over about half the circumference along a position corresponding to the eccentric position of the through hole 3 formed in the partition wall. 5 are formed, and are combined so that the size of a common through hole formed by the through hole 3 of the partition wall and the through hole 5 of the disk changes continuously as the disk 4 rotates. The connection between the disk 4 and the ring 7 attached to the outer peripheral surface of the cylindrical portion 1 is achieved by a connecting member such as a screw.
The ring 7 and the disk 4 are rotated along a through groove 9 for guiding the movement of the connecting member 8 that connects them together. It is done. This groove 9
As shown in FIG. 2, is formed at a corresponding location of the cylindrical portion 1 to which the ring 7 is attached, extending approximately half the circumference thereof in the circumferential direction, and also serves as the rotation axis of the disk 4. The shaft 6 is connected to the bulkhead 2
A reinforcing member 10 including ribs is integrally formed on the surface opposite to the surface on which the disk 4 is disposed, and the shaft 6 is stably held.

The disk 4 mounted in this manner can be easily rotated by turning the ring 7 from outside the cylinder, and the size of the common through hole in the partition wall can be selectively adjusted to a desired size corresponding to the amount of spraying. can.
Changes in this common opening can be easily understood from, for example, the maximum opening as seen in FIG. be done.

In addition, at the opening edge of the cylindrical portion 1' of the cylindrical body,
A pair of fastening members 11 are integrally formed to fit into the discharge pipe at the lower end of the powder/granular agent storage container,
Utilizing this, it is possible to easily attach and detach the discharge pipe.

The adjusting device of the present invention can be put into practical use by attaching marks or symbols to the rotating ring 7 and the cylindrical body, and understanding the relationship between their relative positions and the amount of discharged and sprayed powder and granule for each powder and granule. This is extremely convenient.

[Effect of idea]

The powder and granular agent dispersion rate adjusting device of the present invention has a simple structure, can be easily molded from plastic, and is extremely easy to operate such as installation and removal. Furthermore, the adjustment tool of the present invention can adjust the spray amount by turning the ring 7 after setting the device, and the spray amount can be controlled with high precision, so its practical value is extremely high.
