Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a container for dropping a liquid herbicide which is used by being installed at a water intake of a paddy field or attached to a rice transplanter.

[Conventional technology]

Conventionally, solid grain type herbicides have been generally used as paddy field herbicides, but recently liquid herbicides such as liquid emulsions and flowable agents have been used.

Of these, manual rotary granulators are mainly used for spraying granular herbicides, and power sprayers are mainly used for spraying liquid herbicides.Each of them is widely used, taking advantage of its advantages. are doing.

[Problems to be solved by the device]

However, when spraying a herbicide with a manual rotary granulator, it has to be put into a paddy field for operation, and thus there has been a problem that the spraying operation requires a considerable amount of time and labor.

In addition, the power spreader itself is heavy and not easy to carry, so that there is a problem that an excessive force is required for its operation. For this reason, a weak person such as a woman or an elderly person could hardly use it.

Furthermore, since the above-mentioned manual rotary granulator and power sprayer are not inexpensive, there is a problem that it is expensive to spray the herbicide, whichever is used.

The present invention has been made to solve such a conventional problem, and provides a container for dropping a liquid herbicide that can be sprayed on a paddy field in a short time, labor and cost. With the goal.

[Means for solving the problem]

The container for dropping a liquid herbicide provided by the present invention has a icicle-shaped nozzle tube whose bottom is closed and which is gradually narrowed toward the top, and has an opening with a lid at the top. The container having the nozzle tube has a cutting scale corresponding to the dropping amount of the liquid herbicide put into the container per unit time.

This container is used by suspending it with a tripod at the water intake of the paddy field before rice transplanting. In this case, the liquid herbicide is dropped on the water flowing into the paddy field from the water intake port by cutting the nozzle tube, and is carried on the flow of the water so as to spread all over the paddy field. In addition, this container may be used by being suspended from a rice transplanter. In this case, the liquid herbicide is sequentially dropped after rice planting.

The material of the container can be arbitrarily selected from plastic, metal, glass, etc., but plastic is preferable because it is easy to confirm the remaining amount of the liquid herbicide, the nozzle tube is easily cut, and the container is not easily broken.

The capacity of the container is not particularly limited, but considering the area of the rice paddies in Japan, 0.5-10 l is practical.

The dropping amount of the liquid herbicide per unit time is determined by the factors of the cross-sectional area of the opening when cutting the nozzle tube with the cutting scale and the specific gravity and viscosity of the herbicide. It is provided so as to correspond to the dropping amount determined by the combination.

Further, even with the same dropping amount, the spraying area of the herbicide on the paddy field varies depending on the amount of water per unit time flowing into the paddy field from the water intake port, the moving speed of the rice transplanter, and the like. For this reason, the standard in that case is indicated on the container by a conventional method.

[Action]

(1) A liquid herbicide is put in this container, and the herbicide is suspended in the paddy field before rice transplanting by suspending it with a tripod stand and cutting the nozzle pipe at the required cutting scale. Can be sprayed. In addition, the above-mentioned container can be sprayed with the liquid herbicide on the paddy field at the same time as the rice planting by putting the liquid herbicide in the container, suspending the liquid herbicide at the rear of the rice transplanter, and cutting the nozzle pipe at a required cutting scale. Therefore, according to the container of the present invention, the herbicide spraying work does not require much time and labor.

(2) The container is light in itself and is not so heavy even if a herbicide is put therein, so it is easy to handle and does not require excessive force. For this reason, even weak people such as women and seniors can use it easily.

(3) Since the container is not expensive like a conventional manual rotary granulator or power sprayer, it does not cost much to spray a herbicide.

(4) Since the container is provided with a cutting scale for determining the amount of the liquid herbicide dripped in the container, the amount of the herbicide sprayed on the paddy field should be determined by considering the moving speed of the rice transplanter described above. But you can easily decide.

〔Example〕

FIG. 1 shows a container Y according to an embodiment of the present invention.

In the figure, 1 is a container body having a diameter of 80 mm and a capacity of 1,
Made of plastic. Reference numeral 2 is a nozzle tube provided at the bottom of the container body 1, 3 is an opening provided at the top of the container body 1, and 4 is a lid thereof. Reference numeral 5 denotes an annular ridge provided on the container body 1. The container Y can be attached to the tripod stand by hooking the ridge 5 on a suspension ring of the tripod stand.

The tip portion 2a of the nozzle tube 2 is closed, and the nozzle tube 2 is tapered from the base portion 2b toward the tip portion 2a. The appearance is icicle-shaped (conical). The length of the nozzle tube 2 is 60mm,
The inner diameter of the base portion 2b is 8 mmφ in this embodiment, and the inner diameter of the tip portion is 0.5 mmφ.

Reference numeral 6 is a cutting scale corresponding to the dropping amount of the liquid herbicide put in the container Y per unit time. In this example, a cutting scale corresponding to the dropping amount of the flowable agent having a particle size of 50 to 1500 centipoise and a specific gravity of 1.05 to 1.20 per hour is included.

Even if the dropping amount per hour is determined, the spraying area of the flowable agent on the paddy field varies depending on the amount of water flowing into the paddy field from the water intake port per hour or the moving speed of the rice transplanter. Therefore, although not shown, the container Y has a label indicating a guideline for use in that case.

 Next, how to use the container of the embodiment will be described.

(1) This container Y is first attached to the suspension ring 8 provided at the rear part of the rice transplanter 7 as shown in FIG. 2, or installed at the water intake to the paddy field before rice transplanting as shown in FIG. It is used by attaching it to the suspension ring 9a of the tripod base 9.

(2) Then, the nozzle tube 2 is cut at a required cutting scale. That is, when the flowable agent is dropped on the rice transplanter 7 by taking into consideration the area of the paddy field and the moving speed of the rice transplanter 1,
The dropping amount per time is determined, and the nozzle pipe 2 is cut with the cutting scale 6 corresponding thereto. On the other hand, when the flowable agent is dropped on the tripod base 9 of the water intake port, the drop amount per hour is determined in consideration of the amount of water flowing into the paddy field per unit time, and the cutting scale corresponding to this is determined. The nozzle tube 2 is cut at 6.
Finally, the lid 4 is removed.

As described above, according to the container Y of this embodiment, if the rice paddy is not yet transplanted, it can be hung on the water intake of the paddy field with the tripod base 9 and cut the nozzle tube 2 with the required cutting scale 6 to form the paddy field. A flowable agent can be applied. In addition, at the time of rice planting, it can be sprayed in the same manner by suspending it behind the rice transplanter 7 and cutting the nozzle tube 2 at a required cutting scale 6.
Therefore, the application of the flowable agent does not require much time and labor. This is a great improvement, considering that it has required a lot of time and effort until now.

Further, the container Y of the embodiment is made of plastic and light, and even if a flowable agent is put therein, it is about 1.5 kg, which is not so heavy. Therefore, it is easy to handle and does not require excessive force.
Therefore, even weak people such as women and seniors can use it easily.

Moreover, this container Y is not as expensive as a conventional manual granulator or power spreader. Therefore, the application of the flowable agent is less expensive than in the past.

Further, in the container Y of the embodiment, since the nozzle pipe 2 is provided with the cutting scale 6 for determining the dropping amount of the flowable agent per hour, the spraying amount of the flowable agent on the paddy field is determined by the moving speed of the rice transplanter 7, It can be easily determined by considering the amount of water from the water intake, the area of the paddy field, etc.

[Effect of device]

As described above, according to the container of the present invention, since the constitution as described in the claims is adopted, when the liquid herbicide is applied to the paddy field, it can be applied with less time, labor and cost.
