Description

[Detailed description of the invention] This invention relates to a machine for spraying chemicals targeting pests that parasitize the trunk, branches, and leaf layer (all above-ground parts) of tea plants.

The entire surface of the tea plant is covered with mature leaves, and the inside of the tea plant is densely branched radially from the base of the plant. Furthermore, each type of nozzle for spraying chemicals has its own characteristics, with some types adhering well to branches and others adhering well to leaf layers. Therefore, when trying to apply a chemical solution to the entire tea plant using a chemical spraying machine that combines a conventional nozzle, the amount of chemical solution sprayed is 2 to 3 times.
The amount is doubled, and complete adhesion is not possible.

In addition, there is a lot of scattering on workers, and safety is lacking. Furthermore, there are large variations in the unevenness of spraying and the amount of spraying due to individual differences, skill levels, and fatigue levels of workers.

In order to eliminate the above-mentioned defects, this invention efficiently covers the entire tea plant, and the chemical solution adheres to the entire tea plant as if it had been applied.Furthermore, the chemical solution does not stick to the worker due to scattering, making it easy to handle and work comfortably. This invention relates to a manual whole tea plant control machine for chemical spraying that reduces unevenness in spraying and fluctuations in the amount of spraying due to individual differences, skill levels, and fatigue levels.

The human-powered whole tea tree control machine of this invention will be explained based on the drawings.The frame 1 of the vehicle body a is made of lightweight material, the wheels 3 are attached to the front part of the frame 1 from the center, and the grip handle 2 is attached to the wheels 3. It is fixed to the rear end of frame 1 on the opposite side. A hose connection port 4, a filter 5, and a pressure gauge 6 are provided in the center of the grip handle 2, and are connected to a fan-shaped jet nozzle 8 and an arch-shaped pipe 13 by a high-pressure hose 7 to distribute the chemical solution.

The fan-shaped jetting nozzle 8 is fixed to the front part of the frame 1, and the height of the nozzle, the spraying angle of the nozzle, etc. can be adjusted according to the height of the tea tree using the nozzle vertical adjustment bolt 9 and the nozzle spraying angle adjustment bolt 10. The fan-shaped jet nozzle 8 can be lowered to the lowest position 12 indicated by the broken line.

An arched pipe 13 with staggered nozzles 21, integral with an arched pipe guide 14 suspended from an arched pipe automatic control spring 19 and an arched pipe height adjustment chain 15, is perpendicular to the frame 1; It is slidably attached to two parallel arch-shaped pipe support columns 18 whose upper ends are connected by a horizontal bar by means of 174 slide rings, and further hooked and fixed to a nozzle height adjustment chain hook 16. Further, the arched pipe 13 is moved up and down along the crown surface of the tea plant to correspond to the irregularities of the tea plant during spraying by an automatic arched pipe control spring 19, and furthermore, the arched pipe height adjustment chain 15 can be lowered to position 20 shown by the broken line.

A sheet-shaped anti-scattering cover 24 is attached to the arch-shaped pipe guide 14 in order to prevent the chemical liquid from scattering from the fan-shaped jet nozzle 8 and to promote adhesion of the chemical liquid during spraying.

The sound generation plate 26 contacts the sound generation convex portion 25 of the wheel 3 to generate sound so that the operator can maintain a constant towing speed and uniformly spray a certain amount of chemical solution by the sound generated at regular intervals. A speed control sound generator e was installed in the sound box 27 to further increase the volume.

In addition, this pest control machine is equipped with a fan-shaped jet nozzle tip 11 and an arch-shaped pipe tip 23 so that it can be used even with a power sprayer with a low discharge capacity.
It can spray chemical solutions separately and can be widely used as a pest control device.

In this way, this manual tea plant pest control machine has the feature of being able to uniformly control the entire tea plant under high pressure and at a constant speed.

Note that the pest control machine that controls the entire tea plant can also be applied to a riding pest control machine.

With this design, the chemical solution is sprayed from above the crown surface of the tea plant using the arched pipe 13, and from the bottom of the tea plant using the fan-shaped jet nozzle 8, so that the chemical solution is evenly applied to the entire tea plant, effectively controlling pests and diseases. can. Furthermore, this invention has a scattering prevention cover 24.
This prevents the chemical solution from scattering, reduces the amount of pesticide exposure for workers, maintains a constant pressure and speed using the speed control sound generator e, and the pressure gauge 6, and improves work accuracy based on skill level, fatigue level, etc. It has a feature that prevents deterioration.
