Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved device for applying a chemical solution to kill weeds to weeds.

A chemical solution that kills weeds is a chemical solution that simply adheres to the leaf tips, reaches the roots and underground violets, and kills the entire weed, so perennials can be exterminated, and the herbicide quickly enters the soil. It is already sold as a harmless product and used in various ways to inactivate other crops.

By the way, special care is not required in areas where crops are not grown and there are only weeds, but in areas where crops are grown, sufficient care is required. As a degree,
Therefore, it is difficult to adjust the supply interval of the chemical solution, and in particular, with single-hand applicators, the wetness of the application area must be checked by touching the area.

This invention solves the above-mentioned problem of herbicide applicators, especially the needle-type applicators, and its purpose is to use the capillary phenomenon of the applicator to apply an automatic curve number to cover the required area. It is possible to suck from this tank, and it is +1
The tank part is characterized by a valve that allows negative pressure inside the tank.

Examples of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 (A in this figure is a handle rod, and B is a coating portion connected to the tip of the handle lever with a connecting fitting 1.

For example, the application member B has a side wall Q formed as shown in FIG. (It is also possible to press the rear end of the rope bundle or wrap the liquid supply pipe with a liquid-absorbing coated part such as sponge or felt, which allows the liquid in the liquid suction pipe to be absorbed by capillary action.) Let it seep into the application area of a sponge or the like.

The tank for supplying the chemical liquid to the application member B may be of a backpack type with the vibrator supported on the tip of the handle rod A, but the handle rod A shown in the figure is hollow and also serves as a sealed tank 7, and the tank for supplying the liquid to the application member B can be It is connected to the pipe 5 through a small diameter guide (hole 8), and in Fig. 2 there is also a guide hole 8 in the connecting fitting 1.
The guide hole 8 and the liquid suction pipe 5 can also be connected with a tube. Reference numeral 9 denotes a liquid filling stopper of the tank.

The aluminum handle is provided with an on-off valve 1o interposed between a guide hole 8G from the sealed tank 7 as shown in Figure 3.8
is its opening/closing lever.

Also, as shown in Fig. 2, Figure 4, (I), the handle rod A is provided with a valve C that allows outside air to flow in only when the inside of the airtight tank 7 is depressurized. The valve is valve box 1
A sponge 12 and a valve plate 13 that rides on the sponge are loaded in the interior of the sponge 1. The sponge 12 is in a compressed state and the valve plate 13 is pressed toward the popular port 14 to close the popular port. A weak coil spring can be used instead. Reference numeral 15 indicates a single gasket which is interposed between the valve plate 13 and the popular port 14 and is fixed with a cap 16, and the valve plate has a ventilation notch 17 formed around its periphery G, which is closed by the gasket. It is.

Valve C (this has a small hole 18 in the threaded part of the handle rod A,
This hole is introduced into the closed tank and connected to one small tube 190.

This herbicide applicator has such a structure as described above, and this herbicide applicator supplies a chemical solution from a closed tank to the applicator section 4I at the tip of the handle rod. Since there is a popularity valve that increases popularity only when it becomes 'f1', the applied part in the coating 7yB material (2) When the liquid-containing attachment decreases, the drug 1 night will be tried to be sucked due to the negative phenomenon. When the pressure inside the tank is depressurized, a small amount of outside air is sucked in from the popular valve, and this process is repeated until the applied area is constantly impregnated with the liquid to the extent that it smears, ensuring that the medicinal liquid is applied to the leaf tips (-J). Since there is no dripping, there is no damage to the growing crops, and in this way, the necessary minimum liquid outflow Q''-+1- can be achieved, so the use of chemical solutions (herbicides) can be made extremely efficient. There is an effect.

In addition, the structure of the popular valve is such that the inside of the tank is depressurized and the popular valve is only allowed to open for one time.A valve plate is provided in the valve box to open and close the popular hole, and this valve plate is installed in the valve box in a compressed state. ``Mainly compressed and restored nJ's bullet '1st A and always popular mouth side Q
By using this type of pressure, there is an effect that the structure is extremely simple, and the structure can be made reliably without any problems.
