Here, the relationship between the measuring portion 6 and the introduction path 2 of the support rod 1 and the like will be described. In this embodiment, one of the two measuring holes having a volume corresponding to the amount of spray is selectively used. When the rotary body 8 is rotated so that the entrance 13 at the upper part of one of the measuring holes 11a and the opening 2a of the introduction path 2 of the support rod 1 are aligned with each other, that is, When the powdered material such as pesticides falling from the storage section 5 is introduced into the measuring hole 11a, the discharge port 14 of the measuring hole 11a
Are positioned so as to be closed by the lower lid 10. Therefore, the pesticide and the like stay in the measuring hole 11a and do not flow out downward.

Further, when the rotating body 8 is rotated so that the discharge port 14 of the measuring hole 11a and the inlet 12a of the discharging member 12 are aligned with each other, that is, the pesticide in the measuring hole 11a is discharged, the inlet of the measuring hole 11 is 13 does not coincide with the opening 2a of the introduction path 2 of the support rod 1,
The opening 2a is closed by the upper surface of the rotating body 8. Therefore, pesticides and the like do not enter the measuring hole 11a from the storage section 5.

Further, a rotary drive rod 15 which is one of opening / closing operation units is attached to the center of the rotating body 8.

The rotary drive rod 15 is formed in an elongated shape with a rectangular cross section.
It is attached substantially along the support rod 1.

The lower end of the rotary drive rod 15 is inserted into an insertion hole 8a provided at the center of the rotating body 8, and is fixed by tightening a nut or the like on the lower surface of the lower lid 10 of the measuring unit 6 to rotate it. The upper end of the dynamic drive rod 15 is rotatably attached to the boss 4 on the upper end of the support rod 1.

Further, a lever 16 which is one of opening / closing operation parts is attached by an adjusting screw 16a near the upper end of the rotary drive rod 15.

A return spring 17 is attached to the base end of the lever 16.
Is attached, and the lever 16 has the return spring 17
The lever 8 is biased in one direction by rotating the tip end of the lever 16 toward the front side to rotate the rotary body 8 via the rotary drive rod 15.

Further, in order to make it easy to operate with a finger or the like when gripping the handle 3b, or to adjust to the formation angle β between the measuring hole 11a and the discharge hole 12a of the rotating body 8, the lever 16 and the handle 3b are provided.
The lever 16 is adjustably attached to the rotary drive rod 15 by the adjusting screw 16a so that the moving interval distance between the lever 16 and can be adjusted.

Further, the lower lid 10 can be attached / detached by removing a screw or the like at the lower end of the rotary drive rod 15, and by removing the lower lid 10 and attaching / detaching the rotating body 8 in the outer cylinder 7, By changing the positional relationship with the rotary drive rod 15 around the axis, the plurality of measuring holes 11 formed in the rotating body 8 can be changed and the attachments can be exchanged.

Next, a method of using the powdery or granular material sprayer of the above-mentioned embodiment will be described. First, pesticides and the like are stored in the storage unit 5, and the grip rod 3a is held by the left hand and the handle 3b is held by the right hand. Then, in order to put the pesticide or the like into the measuring section 6, the opening 2a of the introduction path 2 and the inlet 13 of the measuring hole 11 of the rotating body 8 are previously aligned with each other. As a result, the agricultural chemicals in the storage section 5 are discharged through the discharge port 5b to the measuring hole 11
It will be filled inside and a predetermined amount will be measured.

Then, while lifting the sprayer with the gripping rod 3a, the handle 3b
And move it back and forth to orient the tip of the discharge member 12 toward the spot seeding site. Then, pull the lever 16 with your fingertips (arrow a)
Rotate (arrow B). At this time, by operating the lever 16 while holding the grip rod 3a and the handle 3b, the tip position of the discharge member 12 is held constant.

Due to the rotation of the rotating body 8, the inlet 13 of the measuring hole 11a moves and is closed by the upper lid 9, and the discharge port 14 of the measuring hole 11a coincides with the discharge hole 12a of the discharge member 12 as set in advance.

By matching the discharge port 14 of the measuring hole 11a and the discharge hole 12a,
Agricultural chemicals and the like in the measuring hole 11a flow out to the outside through the discharging member 12 and are seeded at appropriate roots of vegetables and the like.

Next, the lever 16 is released and returned to the original position by the return spring 17, so that the rotating body 8 returns to the original position via the rotary drive rod 15, and the opening 2a of the introduction path 2 and the entrance 13 of the measuring hole 11a. And the discharge port 14 of the measuring hole 11a is closed by the lower lid 10. In this state, pesticides and the like flow into the measuring hole 11a from the storage section 5 through the discharge port 5a.

The above sequence is repeated to spray a predetermined amount of pesticide and the like one after another.

In this way, while the measurement is being performed by the one measurement hole 11a and the spraying is being performed, the other measurement hole 11b is not aligned with the introduction path 2, and therefore the other measurement hole is used for the spraying operation. Not offered.

On the other hand, if it is necessary to change the spray amount, lower lid 10
After removing the rotor 8 and pulling out the rotating body 8, with the other measuring hole 11b and the through hole 9a of the upper lid 9 aligned,
The rotary body 8 may be fitted into the rotary drive rod 15 and inserted into the outer cylinder 7, and then the lower lid 10 may be attached at a predetermined position.

As a result, instead of one measuring hole 11a, the other measuring hole 1
1b is communicated with the introduction path 2 and is also communicated with the discharge member 12 by the rotation of the rotating body 8.

In the dust-and-particles applicator of the above embodiment, the rotary body 8 of the measuring unit 6 can be rotated via the rotary drive rod 15 only by operating the lever 16.

Further, various kinds of rotating bodies 8 having measuring holes 11 of various volumes are prepared, and a predetermined amount depending on the type of pesticide or the like can be easily weighed and sprayed or the like.

Moreover, the rotating body 8 is rotated only by operating the lever 16 which is in hand, and the predetermined amount of pesticide or the like can be easily measured only by this rotation.

Therefore, if a granular material such as a pesticide is put in the storage section 5, a predetermined amount of the pesticide or the like can be surely weighed, and there is no overspreading or shortage, no waste occurs, and cost can be reduced.

Further, since the weighed portion 6 can be weighed and the weighed pesticide or the like can be temporarily stored in the weigh hole 11, it can be moved to a place such as spot seeding without flowing out, and the discharge member 12 is provided at the tip. Since it is provided, it is possible to surely perform spot seeding at a spot seeding place or the like. Therefore, the pesticide and the like are not scattered by the wind, and the pesticide and the like are not inhaled with breathing.

In addition, the measuring unit 6 rotatably fits the rotating body 8 in the outer cylinder 7 so that the opening 2a of the introduction path 2 is aligned with the inlet 13 of the measuring hole 11 through the through hole 9a of the upper lid 9. Since the lower cover 10 closes the discharge port 14 of the measuring hole 11,
Agricultural chemicals inside will drop in, and the discharge port of the measuring hole 11
It is possible to reliably measure a predetermined amount without flowing out from 14. Moreover, by providing a plurality of measuring holes 11 in the rotating body 8, it is possible to perform a plurality of kinds of weighings only by changing the mounting position of one rotating body 8.

Further, when sprinkling pesticides and the like in the measuring unit 6, by rotating the rotating body 8 and aligning the discharge port 14 of the measuring hole 11 with the inlet 12a of the discharging member 12 through the through hole 10a of the lower lid 10,
Agricultural chemicals, etc. can be discharged for spot plating. that time,
The entrance 13 of the measuring hole 11 is guided by the rotation of the rotating body 8 into the introduction path 2
Since it does not coincide with the opening 2a, the agricultural chemicals and the like will not enter the measuring hole 11 in excess of the specified amount. Therefore, it is possible to reliably measure the determined predetermined amount.

In addition, since the angle α formed between the fertilizer rod 3a and the handle 3b is formed to be approximately 110 degrees, it is an appropriate operation when the grip rod 3a is lifted with the left hand and the handle 3b is moved with the right hand. You can

Further, since the lever 16 is attached in the vicinity of the grip portion 3, the lever 16 can be operated while holding the sprayer, and since the grip portion 3 and the measuring portion 6 are connected via the support rod 1, In general, the spraying position of etc. is low, but the gripping rod 3a
By operating the lever 16 while holding the handle 3b, the operator can easily rotate the rotating body 8 and position the tip of the discharge member 12 while walking without walking. Therefore, the workability of spraying is improved,
Work can be done easily.

Further, since the rotary drive rod 15 is formed in a rectangular cross section, the rotary body 8 can be easily positioned and rotated.

The shape of the reservoir 5 in the above embodiment is not limited to the rectangular cross section, and may be circular or elliptical.

Further, the outer cylinder 7 and the rotating body 8 of the measuring unit 6 may have any size, and when the number of the measuring holes 11 is large, the diameter of the rotating body 8 may be increased.

The number of measuring holes 11 formed in the rotating body 8 is also arbitrary. For example, when the amount of spraying is constant, one measuring hole 11 is sufficient, and it may be set appropriately according to the spraying form.

Further, instead of the introduction passage 2, an introduction pipe or the like may be provided along the support rod 1 so as to be connected to the discharge port 5a of the storage portion 5 and also to connect the lower end portion of the introduction pipe and the measuring hole 11.

Also, the mounting position of the lever 16 may be below the handle 3b, and a bevel gear or the like may be used to connect the lever 16 and the rotary drive tube 15.

Further, the sectional shape of the rotary drive rod 15 is not limited to the rectangular shape, and may be a hexagonal shape or a circular shape.

Further, this powdery or granular material sprayer can be used not only for point sowing, but also for striking or diffusing cloth, and can also be applied to powdery or granular materials such as fertilizers and seeds.

[Effects of the Invention] As described above, the powdery or granular material sprayer according to the present invention is provided with a storage section for storing powdery or granular materials such as pesticides, and a measuring section connected to the storage section below the storage section. Since it was set up,
The granular material falls and is reliably collected in the measuring hole of the measuring section.

Also, since the measuring hole has a predetermined volume, it is possible to reliably measure a predetermined amount determined for each type of pesticide, etc. by setting it to a predetermined volume in advance, and it is possible to perform a wasteful spraying in the conventional manner. It is possible to carry out an appropriate amount of efficient spraying and reduce the cost.

In addition, since the metering unit is equipped with a discharge unit, it is possible to perform accurate spot seeding at spot seeding points, etc., and from that point as well, it is possible to reduce the cost and to reliably spray the roots of vegetables etc. No scattering and no inhalation of pesticides during work.

Also, since the discharge part can be opened and closed by the operation part provided on the grip part, etc., it can be operated by the remote control method, and the worker can easily perform the work while walking without crouching, so that the spraying work can be performed. It is possible to obtain effects such as improvement of the property.
