Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a portable spreader that is carried by a person (such as a backpack type, a shoulder type, etc.) and is used for, for example, a task of spraying a bud suppression solution on a tobacco tree in order to suppress the shoots of the tobacco tree. is there.
[0002]
[Problems to be solved by the invention]
This type of tobacco tree bud inhibitor solution is effective when only a small amount of bud inhibitor solution is applied to the tobacco tree roots from above when the tobacco tree is small. Is known.
[0003]
However, with a conventional spreader, it is not possible to spray a small amount of spot, so not only a large amount of bud suppression liquid is sprayed, but also the bud suppression liquid spreads over the tobacco tree and spreads over the entire surface. A large amount of bud suppression solution on small tobacco trees, especially on the leaves, the tobacco tree may not grow abnormally. There is also.
[0004]
For that reason, since the spraying of the side bud suppression liquid is done at a time after the tobacco tree that has become less harmful, it is not necessary to suppress side buds when it is small. There is a problem that the spraying effect of the bud suppression solution is halved.
[0005]
[Means for Solving the Problems]
The portable spreader according to the present invention has been made to solve such problems, and by allowing a small amount of spot spraying, only the side root buds of the tobacco tree can be seen from above when the tobacco tree is small. It becomes possible to spray a small amount of the bud inhibitory solution, and there is no harmful effect on the tobacco tree and the human body, and the spraying effect of the bud inhibitory solution can be obtained efficiently at an appropriate time.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. 1 is a schematic view showing the entire spreader, FIG. 2 is a view showing the spreader body of FIG. 1, FIG. 3 is a view showing the spray liquid amount regulator of FIG. 1, and FIG. FIG. 5 is a partially enlarged view of FIG.
[0007]
In FIG. 1 and FIG. 2, 1 is a back-loading type sprayer body, 2 is a tank for storing a spray liquid such as a bud suppression liquid, 3 is a pump for sucking up and discharging the spray liquid in the tank 2, 4 is A manual operation handle for driving the pump 3, 5 is a spring for accumulating the pressure applied by the manual operation handle 4 to make the discharge force of the pump 3 constant, and 6 is a constant pressure spray liquid discharged from the pump 3. It is a discharge port.
[0008]
1 and 3, 7 is a spray liquid amount adjuster provided separately from the spreader body 1, 8 is a liquid supply port connected to the discharge port 6 of the spreader body 1, and 9 is connected to a discharge hose 10. 11 is a communication path that connects the liquid supply port 8 and the discharge hose connection port 9, 12 is an electromagnetic valve disposed in the communication path 11, and 13 is a signal line for turning on the electromagnetic valve 12. 14 is a signal line connection port for connecting 14, 15 is a timer for turning off the solenoid valve 12, 16 is a power source, 17 is a switch of the power source 16, and 18 is a pressure gauge for displaying the pressure of the liquid supply port 8.
[0009]
In the drawing, reference numeral 19 denotes a nozzle hole at the tip of the discharge hose 10, and the handle portion 20 has an ON operation switch 21 connected by a signal line 14.
[0010]
Now, the operator carries this machine on the back and performs the spraying work as shown in FIG. 4. The pump is driven in advance by manual operation of the manual operation handle 4 to supply a constant pressure spraying liquid to the discharge side of the pump 3. Keep it. After confirming that the pressure is constant with the pressure gauge 18 of the spray liquid amount regulator 7, when the ON operation switch 21 of the handle portion 20 is pressed, the solenoid valve 12 is opened and the spray liquid passes through the communication path 11 and the discharge hose 10. It is sprayed from the nozzle 19 through.
[0011]
At this time, the timer 15 operates simultaneously with the opening of the solenoid valve 12 and closes the solenoid valve 12 instantaneously (for example, 0.1 second), so that the amount of sprayed liquid passing through the solenoid valve 12 becomes very small (for example, 2CC) Each time the ON operation switch 21 is pressed, a small amount of spray liquid of about 2CC is quantitatively sprayed from the nozzle 19. As shown in FIG. 5, this very small amount of spray liquid is spot-sprayed from above only on the side root buds 23 of the tobacco tree 22 at a small time.
[0012]
Since a small amount of spray liquid can be spot-sprayed in this way, a small amount of spray liquid can be spot-sprayed from above only on the side buds 23 of the leaf roots when the tobacco tree 22 is small. Therefore, there is no fear of harmful effects on the human body due to the large amount of shoot bud inhibitor spreading and spreading, and the shoot bud inhibitor can be properly sprayed at the necessary time.
[0013]
Moreover, since the spraying work can be carried out with a simple operation of pressing the on operation switch 21 while holding the handle portion 20 of the nozzle 19 continuously, a small amount of spot spraying can be performed continuously. Good and less fatigue.
[0014]
It should be noted that the pump driving force of the spreader body 1 may be driven by the engine 24 as shown in FIG. 4 in place of the manual operation of the manual operation handle 4 described above, and further by electric power. It is also possible to drive the pump.
[0015]
【The invention's effect】
As described above, according to the present invention, by allowing a small amount of spot spraying, it is possible to spray a small amount of the bud suppression liquid from above only on the side buds of the tobacco root when the tobacco tree is small. Thus, there is no harmful effect on the tobacco tree and the human body, and the effect of spraying the side bud inhibiting liquid at an appropriate time can be obtained efficiently.
