Description

[Detailed description of the invention] The present invention relates to a support device used to install a spray head for dispersing chemical liquids in orchards, vegetable gardens, afforestation areas, etc.
The purpose is to facilitate the installation work of the spray head on slopes, strengthen the support of the head, and increase the effectiveness of chemical spraying.

Conventionally, in order to install a rotary pest control spray head in an orchard, etc., a long hard chemical supply pipe 22 is hung from the spray head 21 as shown in FIG. It is slidably attached to a support post 23 provided therein.

However, with this type of support device, although the support height of the head can be changed, the support angle of the head relative to the supply pipe or column remains constant. It is necessary to install the head and support with the entire head tilted so that it can be sprayed.

Therefore, the installation work is troublesome and time-consuming, and the support is unstable, making it impossible to expect long-term use.

In view of the above-mentioned drawbacks of the conventional technology, the present invention allows the user to freely change not only the support height of the spray head but also the angle of inclination of the head with respect to the pillar. It is as follows.

1 is a support that is embedded in the ground G and is made of angle wood.

Reference numeral 2 denotes a support rod made of a pipe or rod, which is held by the support column 1 so as to be slidable up and down and fixed.

In this embodiment, as shown in FIG. 2, a pair of open annular holding fittings 3, 3' are connected in an annular manner and fixed to the column 1, and a supporting rod 2 is attached inside the holding fittings 3, 3'. is inserted, and by tightening a fixing screw 4 screwed into the holding fitting 3, the support rod 2 is pressed and fixed to the inner surface of the angle of the support column 1.

An elbow 2a is fixed to the upper end of the support rod 2, and an elbow 2a is attached to the end of the elbow 2a in a direction perpendicular to the longitudinal direction of the support rod 2 (
A horizontal shaft attachment portion 5 made of a female screw is formed so that the horizontal shaft can be attached thereto.

6 is a spray head, which is composed of a casing 7 that also serves as a gear box, a chemical liquid injection nozzle 8, an impeller 9, an impeller nozzle 10, etc.; It rotates around the tube 11.

A coupling ring 12 is fitted into the chemical supply base pipe 11 at a location close to the spray head 6, and a horizontal shaft 13 made of a threaded rod is protruded from the feed ring 12.

As shown in FIG. 3, the spray head 6 is supported by the support rod 2 by inserting the horizontal shaft 13 into the horizontal shaft mounting portion 5 of the elbow 2a, and is also tiltable about the horizontal shaft 13. The elbow 2a is fixed in an inclined position by tightening the adjusting screw 14 provided on the horizontal shaft 13.

In the illustrated example, the horizontal shaft 13 is provided on the spray head 6 side, but it may be fixed to the support rod 2 and the horizontal shaft attachment portion may be provided on the chemical solution supply base pipe 11.

15 is a flexible pipe for supplying a chemical solution.

The support device of the present invention has the above structure, and the height of the spray head 6 above the ground is adjusted by vertically tightening the fixing screw 4 to slide the support rod 2 up and down, and further by vertically tightening the adjusting screw 14. The spray head 6 is rotated by a required angle around the horizontal axis 13 to adjust its inclination angle.

In this way, according to the present invention, not only the height above the ground of the spray head but also its inclination angle can be changed freely, so in the case of a slope, only the spray head can be tilted to the desired angle as shown in Figure 4. The support rod and column can be installed in a vertical position, making installation easier and less labor-intensive compared to the conventional method of installing the entire spray head and column at an angle, and also reduces the weight of the spray head. Since almost all of the action is carried out along the longitudinal direction of the support rods and columns, the support state is stable, long-term use is possible, and no reinforcing support material is required.

Furthermore, the inclination of the spray head can be changed and adjusted as needed even after the support is erected on the ground, so if the surrounding conditions change, the inclination of the spray head can be changed accordingly to ensure effective chemical spraying at all times. .

Furthermore, since the chemical solution supply pipe and the support rod that is slid and fixed to the column are separate, there is no risk of the chemical solution supply tube being damaged by the member that is fixed to the column as in the past, and liquid leakage is prevented. Also, the spray head can be strongly supported.
