Description

TECHNICAL FIELD The present invention relates to a pesticide spraying device that can easily spray a pesticide on a green.

[Conventional technology]

It is a well-known fact that the management of green grass condition is very important in golf courses.

Therefore, agricultural music, fertilizers, fungicides, etc. are regularly sprayed on the green in order to grow the green grass well.

[Problems to be Solved by the Invention]

However, spraying pesticides such as insect repellents is a very labor-intensive task because workers carry pesticide tanks to the greens in each hole, and spraying pesticides in the morning without a player.・ It must be done in the evening, and pesticides must be sprayed evenly over the entire green, so it must be sprayed when there is no wind.

Due to such various conditions, conventional pesticide spraying has become a more difficult task.

The present invention is an invention developed by the applicant for many years in view of the demands of the industry, and an object thereof is to provide an agricultural chemical spraying device capable of easily spraying agricultural chemicals to green. Is.

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

Several greens around the green one on the golf course
The sprinkling section 3 is arranged in a state of surrounding the sprinklers, the sprinkling sections 3 are continuously connected by the communication pipes 2, and a water guiding pipe 4 for sending water is provided on the side of the green 1. The pipe 2 is connected to the water supply pipe 5, and a pesticide mixing unit 6 for mixing pesticide is provided in the water supply pipe 5 in the middle of the water supply pipe 5.
A predetermined amount of pesticide corresponding to the amount of water passing through the water supply pipe 5 is configured to be mixed by being controlled by the control unit 14, and the pesticide mixing unit 6 is provided for a predetermined time after the mixing of the agricultural water supply pipe 5 is stopped. Is configured to have a water supply pipe cleaning function by being provided so that water can pass through the water supply pipe 5, and the control unit 14 is installed in a place where an administrator can easily operate it. Relates to a pesticide spraying device, which is characterized by interlocking sensors that detect the air volume and direction in the course.

[Work]

The pesticide is mixed in the pesticide mixing part 6 while controlling the control part 14 installed in the place where the administrator can easily work on the water sent from the water conduit 4, and the chemical solution is sprayed from the spray part 3 to the green 1. When mixing pesticides, consider the air volume and direction in the course.

〔Example〕

1 to 4 show an optimum embodiment of the present invention, which will be described below.

FIG. 1 is a schematic diagram of this device, which includes a spraying section 3, a water conduit 4, and a water supply tube 5.
Is the existing pipe used for green watering.

The sprinkler 3 is a sprinkler with a solenoid valve attached,
Opening and closing are performed by a signal from the signal transmission unit 7.

The management unit 8 measures weather conditions for a fixed period of time, and stores, for example, a time when the wind is in a calm state, and at this time, sends a signal to the signal transmission unit 7,
A signal to open the solenoid valve will be sent from the distribution unit 3 to the spraying unit 3 (see the signal path diagram in FIG. 2), or a computer will be installed in the management unit 8 and a wind force measurement sensor will be installed on the green 1 of each hole. It is attached to detect the calm state of each hole and send a signal to open the electromagnetic valve to the spraying unit 3 via the signal transmitting unit 7.

FIGS. 3 and 4 show an embodiment of the pesticide mixing section 6, where reference numeral 9 is a chemical solution tank, reference numeral 10 is a chemical injection pump, reference numeral 11 is a chemical injection valve, reference numeral 12 is a stirring section, reference numeral 13 is a pulse transmission flow meter, Sign
Reference numeral 14 is a control unit, and reference numeral 15 is a solenoid valve.

A signal is sent from the control unit 14 to the solenoid valve 15, the solenoid valve 15 is opened, and when water flows, the pulse transmission flow meter 13 senses the amount of water, and a signal is sent from the control unit 14 to the chemical injection pump 10.
The chemical liquid injection pump 10 is operated, and the chemical liquid in the chemical liquid tank 9 is mixed with the water from the water guiding portion 4 via the chemical liquid injection valve.

The control unit 14 controls the amount of the liquid medicine injected from the liquid medicine tank 9 into the water supply pipe 5 via the liquid medicine injection pump 10. The control unit 14 counts the amount of water passing through the pulse transmission flow meter 13 regardless of the water pressure, sends a signal to the chemical liquid injection pump 10 based on the counted amount, and controls the chemical liquid injection pump 10. Differently, it is controlled so that a desired amount of the chemical liquid is injected into the water supply pipe 5 with respect to the constant amount of water that has passed through the solenoid valve 15.

When the operation of the chemical injection pump 10 is stopped by the control unit 14, the control unit 14 does not immediately close the electromagnetic valve 15 but delays it for several minutes to close the electromagnetic valve 15. Due to the delay in closing the solenoid valve 15, the residual chemical liquid in the water supply pipe 5 is removed and cleaned.

The stirring unit 12 stirs water and a chemical solution, and stirs water spirally in the flow direction.

FIG. 4 shows a chemical liquid mixing unit in which the concept of FIG.

Reference numeral 17 in the figure is a valve.

Since the example uses existing piping equipment as it is as described above, the construction can be performed very easily, and the chemical liquid can be sprayed completely unattended, which is several steps higher than the conventional worker spraying. It can be expected to improve the efficiency of.

In this embodiment, since the inside of the water supply pipe 5 can be cleaned, normal green water sprinkling will not be affected at all.

〔The invention's effect〕

Since the present invention is configured as described above, it provides an agricultural chemical spraying device that can spray agricultural chemicals very easily.
