Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to improvement of a chemical solution storage tank used for controlling fruit trees, agricultural products, and the like.

<Prior art> Generally, in the control work in orchards and farms, the storage tank of the prepared chemical solution is installed on the ground or on the bed of the vehicle, and a power sprayer is also installed near it. , The chemical liquid pumped out of the tank by the pumping action of the power sprayer is sprayed from the discharge nozzle held by the operator toward the fruit tree and the like.
It is customary to use 200 to 2000 liters of synthetic resin products.

<Problems to be solved by the invention> However, in the conventional chemical liquid storage tank, the bottom wall surface thereof is not provided with a liquid collecting function, and the suction hose of the power sprayer is inserted into the inside in a random manner. Therefore, during the above-mentioned control work, if another caregiver keeps the tank in an inclined position and the suction hose does not face the lowest part of the tank, the chemical solution can be completely pumped out by itself. However, it is very troublesome in its work. In particular, in a use state where the tank is bound and fixed to the bed of the vehicle, it is impossible to even operate in the inclined posture.

Further, even when the residual chemical liquid or its deposit in the tank is surely removed and cleaned from the drain port, it is difficult for one elderly person to work this efficiently. In particular, the drain port is slightly higher than the bottom wall surface of the tank, and since it is only covered with a blind plug, for example, a long hose is connected for communication therewith. ,
It is impossible to lightly wash the tank in order to flow the residual liquid from the loading platform of the vehicle to the river or the like.

<Means for Solving the Problem> The present invention intends to solve such a problem, and because of the structure for that purpose, the chemical solution inlet is provided on the top wall of the synthetic resin tank body, while the same is fixed from the bottom wall surface. In a chemical solution storage tank in which a leg seat of a height is formed to project downward, a groove for collecting liquid, which projects less than the above-mentioned leg seat and extends downward, is provided in a row at the center of the bottom wall surface to form the groove. One end of the drain opening is formed in a part of the standing peripheral wall surface forming the tank body, and the periphery of the drain opening is formed as a recess for opening / closing valve protection so as to be depressed from the standing peripheral wall surface. An on-off valve having a size that can be accommodated in the recess is attached to the drain port.

<Embodiment> The concrete constitution of the present invention will be described in detail below with reference to the illustrated embodiment. In FIGS. 1 to 5 showing the chemical solution storage tank, (T) is polyethylene or other hard synthetic resin. It is preferable that the tank body is integrally molded from the above, and it is preferable that the tank body is provided with an appropriate coloring color or the chemical liquid in the tank body can be seen through.

(11) is the top wall of the tank body (T), and a relatively large diameter chemical solution inlet (12) is opened in the center of the top wall. From this, the suction hose (13) of the power sprayer (M) is inserted. (14) is an opening / closing cap for the inlet (12), (15)
Is a hose receiving opening that is also opened at one end of the top wall surface (11), and the residual liquid recirculation hose (16) of the power sprayer (M) will be inserted therein. (17) is an opening / closing cap for the hose receiving port (15).

Further, (18) is a general term for the standing peripheral wall surface in the tank body (T), but in the case of the example shown in the figure, the front wall surface (18a) and the rear wall surface (18b) are curved in an arc shape, while remaining. The left side wall (18c) and the right side wall (18d) are flattened into a flat shape. Moreover, the both side wall surfaces (18c) (18d) are integrally projected upward from the top wall portion (11) by a certain height (H1) to form a pair of left and right rope-restricting ear pieces (19). It is supposed to work.

Reference numeral (20) is a hand-holding groove formed in a pair of front and rear at a mid-height position on both side wall surfaces (18c) and (18d), and an operating hand can be hung on the groove for carrying. (21) is a pair of front and rear rope locking grooves, and a pair of front and rear wall surfaces (18a) (1
8b) and the top wall (11) are lined up. here,
By winding the ropes (R) as shown in FIG. 6, the tank itself can be stably installed and fixed on the loading platform of the vehicle.

Reference numeral (22) is a bottom wall surface of the tank body (T), and a plurality of leg seats (23) are integrally formed so as to project downward from a peripheral portion thereof with a constant height (H2). (24) is a groove for collecting liquid, which is less than the leg seat (23) and protrudes downwardly and integrally, and is arranged in a row in the center of the bottom wall surface (22).

Therefore, when viewed from above, the groove (24) extends to a position directly below the chemical solution inlet (12), so to speak, and accordingly, the suction hose (13) of the power sprayer (M).
Can be introduced and guided into the recess of the groove (24) smoothly by itself, and by forming the protrusion of the groove (24),
While also using this as a reinforcing rib, the bottom wall surface (22)
The support rigidity of can also be reasonably increased.

In that case, as is clear from FIG. 4, if the entire bottom wall surface (22) is set to a funnel shape having the lowest height of the central portion where the collecting groove (24) is located, The effect can be further improved.

Reference numeral (25) is a drain port forming one end of the groove (24), which is open at the center of the lower end of the left wall surface (18c) or the right wall surface (18d), and the opening / closing valve (26) is located here. Is installed. It goes without saying that the opening / closing valve (26) has a base (27) communicating with the drain port (25) of the tank body (T). Its on-off valve (26), as suggested from FIG.
Is located at the corner between the groove for collecting liquid (24) on the bottom wall surface (22) and the left wall surface (18c) or the right wall surface (18d). There is a risk of accidental damage by colliding with other objects.

To prevent this, in the present invention, the left side wall (18
c) or an on-off valve (26) which is formed in a depressed state from the right side wall surface (18d) and has a size that can be accommodated in a recess (28) of a certain depth (D), the tank body (T) It is connected and fixed to the drain port (25) of.

In other words, if the tank itself is tilted, the on-off valve (2
The left wall surface (18c) or right wall surface (18d) is set so that it can hit the ground and the like earlier and protect the on-off valve (26) more safely than 6). .
Further, an extension hose (29) as shown by a chain line in FIG. 6 can be connected to the special mouthpiece (27) of the opening / closing valve (26).

Next, FIG. 7 shows a modified example of the present invention. As is clear from the figure, the groove bottom surface of the liquid collecting groove (24) is gradually lowered toward the drain port (25). It can be set as an inclined slope surface with a constant angle (θ), which can further improve the liquid collection effect.

Further, if the inside of the tank body (T) is subdivided by a plurality of vertical partition plates (30) as shown in the figure, the tank itself can be strengthened, and of course, the ripples of the chemical solution during transportation in the vehicle. Etc. can be prevented and the top wall (1
The introduction guide of the suction hose (13) from the chemical liquid inlet (12) toward the liquid collecting groove (24) of the bottom wall surface (22) of 1) can be performed more stably and reliably, which is extremely useful. Can be said. It should be noted that although the figure shows an overall semi-cylindrical tank, its shape and capacity can be freely selected.

<Operation> When the chemical solution storage tank is used to perform control work to spray the chemical solution onto fruit trees, agricultural products, etc., as is clear from the schematic diagram of FIG. 8, the top wall surface of the tank body (T) While inserting the suction hose (23) of the power sprayer (M) from the chemical solution inlet (12) opening in (11) toward the collecting groove (24) of the bottom wall surface (22), Similarly, insert the residual liquid return hose (16) of the power sprayer (M) into the corresponding receiving port (15) of the tank body (T), and work the discharge hose (31) of the power sprayer (M). The person holds it.

Then, when the power sprayer (M) is operated, the chemical action in the tank body (T) is forcibly pumped out by itself by the pump action, and the tip nozzle (3) of the discharge hose (31) is
It will be sprayed from 2) toward fruit trees. In this case, since the groove groove (24) for collecting the liquid is integrally formed so as to project downward in the central portion of the bottom wall surface (22) of the tank body (T), the storage level of the chemical liquid gradually decreases. , Will be pumped out to the end surely,
There is no risk of residual liquid.

Further, when cleaning the inside of the tank body (T) after the above-mentioned control work is completed, the chemical solution inlet (1
It is sufficient to add water or other cleaning liquid from 2) and open the on-off valve (26) of the drain port (25) to extract the cleaning liquid. At that time, as suggested by the chain line in FIG. 6, by connecting an extension hose (29) of another appropriate length to the mouthpiece (27) of the on-off valve (26), for example, from the loading platform of the vehicle. However, the cleaning liquid can be extracted and removed toward a target location such as a river, and in any case, the tank body (T) should be kept in an inclined posture, and no assistant is required. Even the old people can control the fruit trees by themselves,
The tank can be easily and efficiently cleaned.

Incidentally, other symbols (33) in FIG. 8 are pulleys of the power sprayer (M), (34) are crank mechanisms for converting rotational movement of the pulleys (33) into reciprocating movements of the plunger (35), and (36) ) Is a pump chamber, (37) and (38) are suction valves and discharge valves of the pump chamber (36), (39) is an air chamber, and (40) is a pressure regulating valve.

<Effects of the Invention> In summary, in the present invention, while the chemical solution inlet (12) is provided on the top wall surface (11) of the synthetic resin tank body (T), the same height (H2) from the bottom wall surface (22) is provided. Leg seats (23)
In the chemical liquid storage tank that is formed by projecting downwards, by arranging a row groove (24) for collecting liquid that projects downward from the foot seat (23) to the center of the bottom wall surface (22). , One end of the groove (24) is used as a drain port (25) to open a part of the standing circumferential wall surface (18) forming the tank body (T), and an opening / closing valve is provided around the drain port (25). Protective recesses (28)
As a configuration, an opening / closing valve (26) formed in a depressed state from the standing circumferential wall surface (18) and having a size that can be accommodated in the recess (28) is attached to the drain port (25). Therefore, the problems of the prior art mentioned at the beginning are improved, and there is an effect that even an old man or the like can perform the control work easily and efficiently and the cleaning work inside the tank body (T).
