Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus suitable for applying a chemical solution such as a herbicide to the leaf tips of plants.

Recently, new herbicides have emerged that simply apply to the tips of the leaves of plants, killing the roots of the plants, and once they enter the ground, they become detoxified by microbial decomposition.

However, on the other hand, this herbicide also has the disadvantage of being handled in such a way that, for example, when it is sprayed with a sprayer, it scatters all over the place and even kills useful plants. Therefore,
This herbicide only targets the target plants: In order to selectively kill the target plants, a means for selectively applying and adhering them only to the target plants is required.

The present invention provides an apparatus that can easily selectively apply the above-mentioned plants.

The present invention will be described below with reference to the accompanying drawings. Fig. 1 shows a plan view of an example of the present invention, Fig. 2 shows a side view of the same, and Fig. 3 shows a front view of the same. Furthermore, Fig. 4 is a sectional view taken along the line ■-■ in Fig. 1, and Fig. 5 is a sectional view taken along the line V-V in Fig. 2.
Fig. 6 shows a cross-sectional view taken along the line 1--2. In the figure, reference numeral 1 denotes a chemical liquid application head, and a brush member 3 made of a chemical liquid permeation-retaining material such as felt, sponge, or raised cloth is wrapped around the outer periphery of a hollow cylinder 2. Reference numeral 4 denotes a handle made of a hollow cylinder, which is connected to one end of the coating head 1 via a bendable connecting member 5, and itself constitutes a chemical liquid tank.

The handle 4 is usually preferably made of a transparent synthetic resin material. In the connecting member 5, a coating head holder 6 and a handle holder 7 are connected in an articulated manner by a shaft 9, so that the connecting member 5 is bendable.

Furthermore, the handle receiver 7 and the handle 4 are removably connected via a threaded socket tube 8 attached to the tip of the handle 4. The coating head receiver 6 has fixing pin holes 10-1, 10-2, 10- on a circular arc centered on the shaft 9.
3 is provided, and the handle receiver 7 is also provided with a pin hole 11 at a position corresponding to the fixing pin hole, and furthermore, a lock pin 12 is removably inserted through both of them to form a lock mechanism. There is.

The rear end of the handle 4 is closed by an end wall 13, and a cap 14 that is removably fitted into the threaded socket tube 8 is removably attached thereto. Further, the coating head receiver 6 and handle receiver 7 are communicated by a flexible conduit 15 wrapped around the shaft 9.

The hollow cylinder 2 of the coating head 1 is provided with a partition bed 16, and the upper cylinder wall of the partition bed 16 is further provided with a chemical liquid leaching hole 1'7.

Therefore, the space above the partition floor 16 and the space inside the handle 4 are communicated through the flexible conduit 15. Thus, in FIGS. 1 to 6, the lock pin 12 is inserted into the fixing pin hole 10-1, so that the connecting member 5 is fixed straight, but as shown in FIG. When the pin 12 is inserted into the fixing pin hole 10-2, it is bent and fixed. During normal use of this device, first, the threaded socket tube 8 and the handle receiver 7 are disengaged and removed, and the liquid medicine A is stored in the handle 4 from the mouth of the socket tube 8. Then, the handle 4 is connected again with the socket tube 8, and is used, for example, while being fixed in the bent state shown in FIG.

In this way, the chemical solution A is introduced into the space above the partition bed 16 of the coating head 1 through the flexible conduit 15, and is further exuded from the chemical solution leaching hole 17 and held by the brush member 3.

Therefore, as shown in FIG. 8, the operator selects the weeds to be killed,
By contacting the leaves of the weed tree, it is possible to selectively apply the chemical solution. If the inclination angle of the place where the coating work is performed changes, the bending angle of the connecting member can be changed and adjusted to an angle that makes the work easier. When this device is not used, remove the handle 4 from the screw socket 8, remove the cap 14 attached to the rear end as shown in FIG. 9, and attach the cap to the screw socket 8. By doing this, leakage of chemical solution A can be prevented.

It should be noted that the locking mechanism of the bending connecting member in the present invention is not limited to the above-mentioned combination of the fixing pin hole and the locking pin, and it goes without saying that any other locking mechanism such as a ratchet mechanism may be used. .
