Description

[Detailed Description of the Invention] The present invention particularly relates to a tea plant sprayer for spraying chemical solutions such as insecticides and disinfectants on tea plants.

In the past, various types of sprayers for gardening have been devised, but in the case of tea plants with densely packed branches and leaves, it is difficult to spray the chemical solution into the inside of the tea plant, and if you force the sprayer into the tea plant, it may cause problems. This was a problem because it caused damage to leaf pieces and branches, leading to a decline in the quality of the product. Therefore, we sprayed the inside of the tree upwards from the lower part where there were no branches, but the chemical solution did not reach the desired areas and we could not expect much effect.

The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks, to provide a sprayer that facilitates spraying into the interior of a tea plant where leaves and branches are densely packed, and is highly effective in exterminating pests and diseases. .

The present invention is a gun-shaped sprayer that has a cylindrical barrel member with a rounded tapered tip, which facilitates insertion of the barrel member into the tea plant, and which allows chemical liquid to be sprayed from multiple locations on the barrel member. An embodiment of the present invention will be described below with reference to the drawings.

In the illustrated example, reference numeral 1 denotes a cylindrical barrel member with a rounded tapered tip, one end of which is attached to a handle member 3 by a connecting nut 2. A flow path member 4 in which a liquid flow path is formed is screwed onto the handle member 3 side at the attachment point between the barrel member 1 and the handle member 3, and the flow inside the handle member 3 is caused to flow through the flow path member 4. The passage 5 and the inside of the barrel member 1 are in communication. Further, a valve body 7 is provided at the opening of the flow path member 4 and is pressed against the opening by a spring 6, and a valve rod 8 of the valve body 7 is protruded to the outside of the handle member 3. An adjustment nut 9 is screwed together. Reference numeral 10 denotes a trigger member, the upper part of which is pivotally connected to a protrusion 11 formed on the upper part of the handle member 3 by means of a bolt 12, and at the same time a pressing member 13 and a screw 14 which are in contact with the adjustment nut 9.
It is pivoted on. Further, the lower end of the flow path 5 of the handle member 3 can be connected to a pressurized chemical source (not shown) through a joint 15. Furthermore, an injection nozzle 16 is provided at a suitable location on the outer peripheral surface of the gun barrel member 1, and the injection nozzle 16 consists of a nozzle body 17, a member 18 having a spiral groove on the outer periphery, and a small hole at the tip. It is made up of Natsutto 19.

In addition, a plurality of injection nozzles 16 are provided at appropriate positions above and below the gun barrel member 1 as shown in the first drawing, and at appropriate positions on the left and right sides of the gun barrel member 1, and a liquid flow path is narrowed in the gun barrel member 1 as shown in the second drawing. Alternatively, as shown in the third figure, a small diameter pipe 21 is inserted into the barrel member and the pipe 21 is inserted into the connecting member 2.
2 to the flow path member 4, and the injection nozzle 1
6 may be communicated with this small diameter pipe 21.

When spraying a chemical solution inside dense branches and leaves, connect a hose or the like to the joint 15 to connect the pressurized chemical source and the flow path 5 in the handle member 3, and then move the barrel member 1 onto the desired tree. insert it inside,
If you grasp the handle member 3 and pull the trigger member 10,
The trigger member 10 rotates as shown by the arrow with the bolt 12 as a fulcrum, and at the same time, the receding pressing member 13 presses the adjusting bolt 9 backward, so the valve rod 8 retracts, and the valve body 7 becomes a flow path member. Open opening 4. Therefore, the pressurized chemical liquid passes through the flow path member 4, reaches the inside of the gun barrel member 1, and is sprayed from the spray nozzle 16 vertically and horizontally. Furthermore, when the trigger member 10 is released, the valve body 7 closes the opening of the flow path member 4 by the action of the spring 6, and the spraying of the chemical solution is stopped. At the same time, the valve rod 8 is also returned to its original position, and the adjustment bolt 9, the trigger member 10 is also returned to its original position via the pressing member 13. In this way, the chemical solution inside the tree is sprayed while the gun barrel member 1 is inserted into a desired location inside the tree, and if the tip of the gun barrel member 1 is rounded, insertion can be performed more smoothly.

As described above, according to the present invention, a cylindrical barrel member with a rounded tapered tip can be easily inserted from above into a desired location within a tea plant to spray a chemical solution. In addition, it can be easily inserted and removed without causing any abrasion or damage to the leaves or branches of tea plants, and it also allows for easy and thorough disinfection of the backsides of leaves and other areas where chemicals could not reach conventionally, preventing pests and diseases. Extermination can be carried out extremely effectively.
