2. Description of the Related Art Pesticides are indispensable for modern agriculture, for example, they are used for exterminating pests and pests that damage crops and for removing weeds that grow on cultivated land. There are various forms of this pesticide, such as powder and liquid, so the equipment for spraying is also a duster depending on the form,
There is a sprayer. There are various types of dusters for spraying pesticides in powder form, from manual type to hand push type, gear whirl type, to power dusters with several horsepower, and sprays to spray liquid substances. There are various types of machines, ranging from foot-operated and backpack type to power sprayers. These devices are used properly according to the scale of the agricultural land.

One of the granulators for spraying a granular pesticide on a relatively small-scale cultivated land includes a pesticide storage section and a pipe section connected to the storage section. This granulator does not use power, and sprays the pesticide stored in the storage part by ejecting the pesticide stored in the storage part from the ejection port at the tip of the pipe part by shaking the pipe part left and right. This type of granulator is widely used because of its simple structure, light weight and easy handling.

By the way, recently, one of the environmental problems is the influence of pesticides on the natural environment. The consideration of this problem and the improvement of the pesticides itself led to revision of the drug administration standards. Has reduced the amount of agricultural chemicals applied to a given planting area to about one-third of the conventional amount.

[0005]

For this reason, an improvement was made in the above-mentioned granulator by making the diameter of the spout slightly smaller and suppressing the amount of pesticide spouted from the spout. Since the diameter of the spout was smaller than the size of the grain, there was a problem that pesticides were likely to be clogged near the spout. Therefore, in the above conventional granulator,
During the spraying work, every time the pesticide was clogged up, the work had to be interrupted, and the pipe part had to be shaken or tapped to eliminate the clogging, which could cause the spraying work to be inefficient. The present invention has been made in view of the above-described phenomenon, and an object of the present invention is to provide a granulator that prevents the granular material from becoming clogged during use.

Further, the storage portion 2 is provided with an opening 3 with a fastener for storing the pesticide therein, and a shoulder strap 4 whose length can be adjusted is attached. One end of a bendable rubber bellows 5 (bending portion) is fixed to the front end of the bottom of the storage portion 2 by a stopper 6a, and a pipe portion 7 is fixed to the other end of the bellows 5 by a stopper 6b. ing.

As shown in FIG. 2, a spray amount adjusting mechanism 9 is provided at the jet outlet 8 at the tip of the pipe portion 7. That is, the pipe portion 7 is a large-diameter pipe 10 that also serves as a grip portion.
And a small-diameter pipe 11 inside which the pesticide actually flows. Circular plates 12 and 13 are fixed to the front and rear of the pipe 10 so as to plug the pipe 10, the pipe 11 is arranged on the inner wall surface of the pipe 10 in a slightly biased state, and the end portions 14 and 15 thereof are plates. 1
The holes 16 (first holes) and 17 provided in the Nos. 2 and 13 are fitted and fixed.

As shown in FIG. 3, a shaft 18 is fixed to the center of the plate 12 in a state of protruding toward the outside, and a rotating circular movable plate 19 is attached to the shaft 18.
A (plate body) is rotatably attached by inserting a shaft 20 through a hole 20 provided in the center of the plate body, and a spring 21 for holding the movable plate 19 and a spring holding metal fitting 22 are attached to the tip end portion thereof. There is. The movable plate 19 has holes 23, 24, 25 through which pesticide is sprayed around the holes 20.
(Second hole) is provided. These holes 23, 2
4 and 25 have slightly different diameters, and the movable plate 19 has a ball ratchet mechanism (not shown).
Are rotated step by step so that they communicate with the holes 16 of the plate 12 one by one.
Therefore, by rotating the movable plate 19, the holes 23, 2
By switching between No. 4 and No. 25, it is possible to adjust the amount of the pesticide to be ejected. It is also possible to close the ejection port 8 by making the portion of the movable plate 19 where the hole is not provided correspond to the hole 16.

As shown in FIG. 1, a prevention mechanism 26 is provided near the tip of the pipe portion 7. That is, an annular support body 27 is attached to the tip of the pipe portion 7 so as to pass the pipe 10 inside, and a container body 28 is attached to a lower portion of the support body 27 in a direction orthogonal to the pipe 9. It is installed toward. The container body 28 is formed by adhering end plugs 30 and 31 to the front and rear of a cylindrical main body 29, and inside thereof, an iron ball 32 having a diameter slightly smaller than the inner diameter of the main body 29.
Two (rolled animals) are arranged so that they can roll freely.

Further, a diffusion nozzle 33 is attached to the tip of the pipe portion 7 so that the ejection port 8 is housed inside. The diffusion nozzle 331 is for diffusing the pesticide emitted from the ejection port 8 in a wider range.

In use of the granulator 1 constructed as described above, first, the pesticide is put in the storage part 2 and the size of the ejection port 8 is selected according to the amount of the pesticide to be sprayed. Then, the pesticide is ejected from the ejection port 8 and is scattered by holding the pipe portion 7 and shaking it to the left and right toward the cultivated land for spraying.

At this time, as shown in FIG. 4, if an operator (not shown) holds the pipe portion 7 and shakes it from right to left, in the state A in which the pipe portion 7 is moving leftward, the container body 28 The iron ball 32 inside hits the right end plug 30, but when the pipe part 7 is swung to the left in the state of B, it collides with the left end plug 31 for a moment after the movement of the pipe part 7. This impact is transmitted to the pipe portion 7 as vibration, and the effect of loosening the pesticide that is clogged near the tip of the pipe portion 7 is obtained. The pipe part 7 has exactly the same effect.
Can also be obtained by swinging from left to right.

Since the pesticide is disentangled in the vicinity and it can be prevented. It is also possible to rotate the movable plate 19 to select the size of the ejection port 8 and adjust the amount of the pesticide to be sprayed as necessary. Furthermore, iron ball 32
By reciprocating inside the container body 28, a certain rhythm is generated in the operation of shaking the pipe portion 7, and an operator also operates the granulator 1 in accordance with this rhythm to create a rhythm in the work. Efficiency can be expected.

Although a bellows made of rubber is used between the storage portion and the pipe portion in the present embodiment, other parts can be used as long as the pipe portion can be easily operated and is not easily deteriorated by the bending operation. A material having the same material and shape may be used. Further, although the prevention mechanism is configured such that two iron balls reciprocate inside the hollow cylindrical container body, the mounting position and shape of the container body are taken into consideration in consideration of how the impact is transmitted and the size. Also, the number of iron balls may be changed. Further, in the present embodiment, an apparatus for dispersing granular pesticides has been described, but it can be sufficiently used for spraying not only pesticides but also fertilizers, crop seeds and the like.

[0021]

As described above, according to the granulator according to the first aspect of the invention, the prevention mechanism vibrates the tip of the pipe portion by the action of swinging the pipe portion left and right to eject the particulate matter. It is possible to prevent clogging near the exit.

According to the granulator of the second aspect, the diameter of the ejection port is changed by associating the plurality of second holes having different diameters with the first hole one by one, and the pipe portion is A single swing can increase or decrease the amount of ejected granular material to adjust the spray amount.

According to the granulator of claim 3, the reciprocating animal reciprocates in the container body, so that the pipe part can be suitably shaken and the impact by the reverting animal has a constant rhythm. However, it is expected that a rhythm will be created and work efficiency will be improved.
