Description

[0001]
[Industrial applications]
The present invention relates to a liquid injection device for activating a soil by injecting a liquid into a turf such as a golf course.
[0002]
[Prior art]
In a golf course, there is no device that uses a single machine to perform a device for spraying a chemical solution on a turf surface and an irrigation device for injecting a high-pressure liquid into the soil.
[0003]
[Problems to be solved by the invention]
For this reason, different types of machines must be prepared when spraying the turf surface and when performing irrigation work, which increases the management cost. There is a disadvantage that the work machine must be brought to the work place, which is complicated.
[0004]
[Means for Solving the Problems]
The present invention has been proposed in view of the above problems, and has taken the following technical measures. That is, the tanks 3 and 4 for accommodating the spraying chemical and irrigation liquid medicine respectively provided in the carrier 2 of the mobile vehicle, during both tanks 3,4 switching valve 7 to allow communication of these tanks 3, 4 to each other And a high-pressure pump 14, an engine 12, and a low-pressure pump 15 are arranged on the rear carrier 2 of these tanks 3, 4 in the width direction, and the high-pressure pump 14 and the low-pressure pump are connected to the engine 12 via clutches 16, 17. 15, an irrigation machine 28 is connected to the high-pressure pump 14, and a sprayer 30 is connected to the low-pressure pump 15 via a pipe. The irrigation machine 28 is supported by a lifting link 34 at the rear of the carrier 2 so as to be able to move up and down. The sprayer 30 is provided with a hose 38 having a plurality of ejection parts attached to three divided frames 37a, 37b and 37c. When the irrigation machine 28 is used, the lifting link 34 is lowered to lower the irrigation machine 2. When the sprayer 30 is used, the irrigation machine 28 is raised, the left and right frames 37b and 37c at both ends of the central frame 37a are opened, and the chemical solution is hosed while the vehicle is advanced. The liquid injection device is characterized in that the liquid is injected from the 38 injection portions .

【Example】
Hereinafter, embodiments of the present invention will be described based on embodiments shown in the drawings. First, a description will be given of the configuration. Reference numeral 1 denotes a truck as a mobile vehicle having a loading platform 2 on which two tanks 3 and 4 are mounted close to each other in the front-rear direction. A communication pipe 5 for communicating the tanks 3 and 4 with each other is provided at the bottom of the tanks 3 and 4, and a switching valve 7 is provided in the middle of the communication pipe 5.
[0006]
8 and 9 are lids provided on the upper surfaces of the tanks 3 and 4, and 10 and 11 are water level meters provided on the side surfaces of the tanks 3 and 4. The front tank 3 contains a chemical solution for soil irrigation, and the rear tank 4 contains a chemical solution for surface spraying. An engine 12 as a drive source is mounted behind the rear tank 4, and a high-pressure pump 14 and a low-pressure pump 15 are connected to left and right sides of the engine 12 via clutches 17 and 18, respectively.
[0007]
The high-pressure pump 14 and the low-pressure pump 15 are provided with accumulators 20 and 21 for absorbing pressure fluctuations. Reference numerals 22 and 23 denote pressure regulating valves for adjusting pressure, and reference numerals 24 and 25 denote pressure gauges. An irrigation device 28 for injecting high-pressure liquid into the soil is provided below the high-pressure pump 14, and a sprayer 30 for spraying low-pressure liquid is provided below the low-pressure pump 15.
[0008]
The irrigation machine 28 includes six electromagnetic valves 31, 31, six nozzle lances 32, four nozzles 33 attached to each nozzle lance 32, and a microcomputer (not shown). The electromagnetic valves 31 are controlled by a controller so that high-pressure (350 kg / cm 2) liquid is ejected from the nozzles 33.
[0009]
As shown in FIG. 1, the irrigation machine 28 is connected to the back of the bed of the truck 1 via a lifting link 34 so as to be rotatable up and down, so that it can slide on the ground. Reference numeral 35 denotes a resin cover that covers the outer periphery of the irrigation device 28, and is configured so that only the nozzle 33... Peripheral portion is opened and the other portions are covered with the cover 35.
[0010]
The irrigation machine 28 can be moved up and down using a hydraulic or electric motor or the like, and rotates the lifting link 34 upward during non-operation. On the other hand, the sprayer 30 is configured such that a hose 38 having a plurality of ejection parts is attached to three divided frames 37a, 37b, 37c at the rear part of the body, so that a chemical solution or the like can be ejected from the ejection parts. I have.
[0011]
The left and right frames 37b and 37c may be manually opened and closed with respect to the center frame 37a, but may be opened and closed using a power source such as an electric motor. Next, the operation of the above example will be described. When a high-pressure liquid or a chemical is injected into a turf at a golf course or the like, the tank 3 is filled with water or a chemical, the clutch 16 is connected, and the high-pressure pump 14 is driven by the engine 12.
[0012]
Then, output conditions such as the ejection amount of the nozzle per injection and the number of injections per unit time are set for a controller (not shown), and a drive pulse is given to the electromagnetic valve 31. Then, a high-pressure liquid adjusted to a predetermined pressure spouts vigorously and intermittently from the tip of the nozzle 33, and crushes hard soil while opening deep pores in the soil. At this time, if the spraying operation is not performed and only the irrigation operation is performed, the spraying tank 4 is also filled with the same liquid, and the switching valve 7 is switched to the communication side to increase the tank capacity. Irrigation work can be continued.
[0013]
When only the spraying operation is performed, the clutch 16 is disengaged, and the clutch 17 on the opposite side is connected to drive the low-pressure pump 15. Then, a low-pressure liquid of about 35 kg / cm 2 is sent out by the pump 15 and is sprayed from the spout of the hose 38 onto the surface of the lawn. In this case, if only the spraying operation is performed, the switching valve 7 can be switched to the communication side, and the tanks 3 and 4 can be filled with the same chemical solution to perform the spraying operation, as in the case described above.
[0014]

The sprayer 30 is supported on the rear of the loading platform 2 by a lift 34 so as to be able to move up and down. A hose 38 having a plurality of ejection parts is attached to three divided frames 37a, 37b and 37c. The lowering link 34 is lowered to advance the vehicle in a state where the irrigation machine 28 can slide, and when the sprayer 30 is used, the irrigation machine 28 is raised and the left and right frames 37b and 37c at both ends of the central frame 37a. Is opened so that the chemical is ejected from the ejection portion of the hose 38 while the vehicle is moving forward , so that one machine can selectively perform two different operations, irrigation and spraying. In any case, the work can be performed while the vehicle is running without stopping the vehicle, so that the efficiency of the work is improved and the maintenance and management become easier as compared with a case in which each of the machines has a different machine.
