Abstract

PURPOSE:To provide the title sprinkler improved in the automation for the pesticide application on golf courses, so designed that on the way of the piping to a sprinkler, an electromagnetic valve to open and close the water current for applying water and an ejector to mix the water current and a pesticide in a cartridge tank fitted are set up. CONSTITUTION:On the way of the piping to a sprinkler 3 to apply water on the turf of golf courses, (A) an electromagnetic valve 5 to open and close the water current for applying water and (B) an ejector 8 to mix said water current and a pesticide in a cartridge tank 7 fitted are set up. Such cartridge tank 7 containing a pesticide corresponding to the type of turf such as for teeing ground, fairway, rough or green is selected in accordance with the purpose, and the sprinkling time is regulated through opening and closing the electromagnetic valve, thus improving the automation of the pesticide application on golf courses.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an automatic agrochemical spraying device for a golf course that automatically sprays agrochemicals onto the lawn of a golf course.

(Conventional technology) Conventionally, the spraying of pesticides at golf courses has mainly relied on human power using manual pumps, and workers walk around the golf course carrying tanks containing pesticides and manual pumps on their backs to spray pesticides. ing.

In addition, it is necessary to manage not only the lawn but also other trees, and this work is quite difficult.

(Problems to be Solved by the Invention) The following three types of work are required to manage lawns and trees.

(1) Weeding to remove other weeds to make the lawn more beautiful, ■ Insecticide to exterminate pests, and ■ Sterilization to prevent lawn diseases.

The pesticides required for each of the above operations are divided into herbicides, insecticides, and fungicides, so workers must replace the chemical tank each time. Furthermore, in order to avoid bothering the players, pesticide spraying is often carried out at night, which places an even greater burden on the workers.

In addition, there are many types of grass, and different types of grass are used for teeing grounds, fairway, rough, green, etc.
Furthermore, even within the same golf course, changes occur in the growth of lawns due to differences in factors such as location, orientation, altitude, wind direction, wind speed, and sunshine hours, so it is currently difficult to adapt pesticide spraying operations to each change. difficult,
Therefore, we are forced to rely on the greenkeeper's experience and intuition.

This inevitably leads to the large-scale spraying of various pesticides, which not only makes it difficult to manage the spraying operation, but also poses problems from an economic and environmental perspective.

The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a rational automatic pesticide spraying device for a golf course that can automatically spray pesticides and easily manage the amount of pesticides used. There is.

[Structure of the invention]

(Means and effects for solving the problems) The present invention provides a solenoid valve that opens and closes a water flow for watering in the middle of piping to a sprinkler that sprinkles water on the lawn of a golf course, and a pesticide in a cartridge tank installed. This system is equipped with an ejector that mixes pesticides into the sprinkler water stream, and sprays the pesticides on the lawn by mixing them with the sprinkler water. The spraying time is adjusted by selecting the cartridge tank containing the pesticide and opening and closing the solenoid valve, thereby improving the automation of pesticide spraying on golf courses.

(Example) An embodiment of the present invention is shown in the drawing.

FIG. 1 shows a case where the present invention is applied to spraying pesticides on greens. Water stored in a storage tank 1 is pumped by a water pump 2 to a sprinkler 3 via piping 4, and is jetted onto a green 9. Let the water disperse.

When not spraying water, close the waterway with solenoid valve 5.
t Use the manual valve 6 when the solenoid valve breaks down or when inspecting it.

When it is desired to spray pesticides, the cartridge tank 7 containing the pesticides is inserted into the ejector 8, and the pesticides are sprayed together with the water by mixing it with the water in the pipe 4.

That is, the pesticide to be sprayed is placed in the cartridge tank 7 in advance and attached to the ejector 8, and the water pump 2 is operated to send water stored in the storage tank 1 through the pipe 4A, which is kept open at all times. Pass through manual valve 6.

Next, when the solenoid valve 5 is operated to "open", the water in the storage tank 1 that has been pumped by the water pump 2 is transferred to the solenoid valve 5 and the ejector 8.
The agricultural chemicals in the cartridge tank 7 are mixed into the water by the ejector 8, and the water containing the agricultural chemicals is sent to the sprinkler.
3, it is scattered to green 9. To stop, operate the solenoid valve 5 ``close''. When pesticides are not being sprayed, the cartridge tank 7 can be removed to spray only water.

〔Effect of the invention〕

As explained above, according to the present invention, pesticides are sprayed using sprinklers, so the sprayed area is fixed, accurate spraying of pesticides is possible, and the pesticides are sprayed automatically. This eliminates toxic effects on workers and allows unmanned spraying of pesticides at night, reducing labor costs and eliminating the burden on players.

In addition, by setting the sprinkler jet time and the amount of pesticide in the cartridge tank, it is possible to spray the prescribed pesticide on the lawn, so there is no need to rely on experience or intuition, and there is an accurate pesticide spraying algorithm based on data. It becomes possible to spray pesticides according to the following.

Additionally, since sprinklers, which are essential for golf courses, are used, pesticide automation can be done with a relatively small investment.

Note that when the water source is not a storage tank but a dam, a pressure tank, etc., the same effect can be obtained even without a water supply pump as long as other configurations are the same.
