Description

Green Aerators {GREEN AERATOR}

The present invention relates to a golf course turf management system that can be adjusted according to the environmental conditions of climate, temperature, humidity, drying. In particular, the present invention by installing a lawn management system for each golf course course to be managed automatically by a computer at the management office to protect the grass at the same time to effectively manage the lawn in the summer when the snow is a lot of snow and summer when the rain is high The green aerator will allow golfers to enjoy golf on a comfortable course at all times.

Conventional systems are known to manage soil and grass by blowing and / or inhaling air through a perforated duct network located beneath the grass. For example, commonly owned US Pat. Nos. 5,433,759, 5,507,595, 5,542,208, 5,617,670, 5,596,836, 5,636,473 represent different versions of a device used for this purpose, each of which is an invention. It is incorporated herein by reference. Since an air pump or nonreversing blower discharges air from one connection and air is injected from the other connection, changing the blowing function from the blowing function to the suction function changes the duct network to the pressure outlet of the blower. It needs to be disconnected from and connected to the inlet. To this end, various valves and / or couplings can be used to avoid the confusion associated with selectively connecting and disconnecting the duct network from multiple ports of the blower.

Manual operation limits the degree to which use can be automated. In addition, considerable judgment is concerned with knowing when to introduce air into the duct network and when to control the air from the duct network by applying a partial vacuum. For example, introducing air into the duct net when there is too much moisture in the soil profile can cause serious damage to a portion of the turf.

The invention, generally owned in US Pat. No. 6,273,638 and whose disclosure is incorporated herein by reference, includes an air handling device connectable to a duct network below a grass field and at least one arranged to measure a variable associated with the field. An additional feature of the air handling system is disclosed that includes a sensor and a control module connected to the air handling device to control operating parameters of the air handling device in response to an output from the sensor. Variables associated with the field include temperature and humidity. Parameters of the air handling device include the direction of the air flow, the temperature of the air directed into the duct network and the operating time of the unit. The system optionally includes programmable control logic to allow the sensor output to automatically control the operating parameters of the system. The sensor output can be displayed on the computer display to allow the user to manually control operating parameters if desired. Conventional turf treatment systems are often best known for their ability to remove excess moisture from soil profiles to improve playability for golf greens and playgrounds. For example, a system manufactured by SubAir Systems of Graniteville, South Carolina, is characterized by a quick return of the green to a tight, fast condition during major golf tournaments and to keep water from accumulating in the fairways and pedestrian areas. This feature minimizes downtime and makes the course safer for the crowd during inclement weather.

Also not well known in golf course turf care is the crop benefit obtained by injecting fresh air into the soil profile. Fresh air is injected into the profile whenever excess moisture is removed. Excess moisture and low levels of oxygen are major causes of turf disease. Grass may also suffer from problems when the level of moisture in the soil profile is not excessive due to poor air quality in the soil profile. There are several factors due to the fact that the roots of plants need oxygen for respiration. Through the process of respiration, the plant uses available oxygen located in the pore space between the sand particles in the profile and replaces it with carbon dioxide.

Deterioration of soil air quality is accelerated when plants are under pressure due to an increased rate of plant respiration. In addition, oxygen is deprived and additional gases are produced as by-products of organic matter degradation within the soil profile due to microbial activity. Microbial activity

It will change depending on the weather conditions with a mean and ideal humidity. Finally, gases such as methane and hydrogen sulfide can exist natively around the soil. Since the soil air quality can vary depending on the soil humidity level, it is advantageous to exchange the soil gas regularly and regularly to ensure optimum growth conditions for the grass. However, general business practice is inconsistent, mainly by treating the grass after rain. Some golf courses perform turf treatment once or twice a week, but this will not achieve optimal results when the turf is particularly stressed.

Therefore, in order to solve the problems as described above, the "grass management system of the playground and the lawn management method of the golf course" of Publication No. 2009-0046901 (prior art 1) has been proposed.

Prior art 1 is directed to a system and method for conditioning grass in one or more golf course areas to provide one of a subsurface aeration conduit for aeration of the area and one of vacuum and pressure modes of vacuum mode in the conduit. And an aeration subsystem having an air blower unit in flow communication with the aeration conduit, wherein a control module is provided to respond to commands to control the operation of the aeration subsystem in response to detection of environmental parameters. The module operates the blower in each intermittent operation cycle in one of the vacuum mode and the pressure mode, each cycle comprising a blower "on" and a blower "off" mode, in which the blower "on" mode is the first time. The blower unit is operated during the interval and the blower " off " It can be seen that the configuration is made to stop the operation of the air blower unit.

As another prior art, "the management device of the grass playground" of Korean Patent No. 0333339 (prior art 2) is to supply water to the bottom of the lawn and to provide a suction and pipe so that the grass can grow. It is related to the management device of the grass playground, which can supply water, discharge it immediately when it rains, and supply heat to the lawn and epidermis in winter so that the grass prevents the grass from freezing in winter. The grass is good because it can supply water to the lawn through the branch pipe where the discharge ball is drilled, so that water can be supplied regardless of the season or climate change. In particular, even if the rain does not fall due to drought, the grass is good. To be able to develop quickly, and it rains a lot in the rainy season In case of water accumulation, it can maintain the condition of the lawn by operating the supply discharge pump in the state of vacuum suction to discharge the water from the lawn and keep the condition of the lawn in good condition. It can keep the grass green all year round because it can keep the warm state by supplying steam to circulation and prevent the freezing of the lawn and surface layer. Especially, even if snow falls in the winter season and accumulates on the grass, it can be immediately melted by hot wire or steam. Since a state can also be kept dry, the structure which was able to keep the condition of the ground always in a good state is known.

As can be seen in the prior arts 1 and 2, when the supply pipe and the discharge pipe are installed in the lower part of the playground grass as a device for managing the lawn playground from the application date of the prior art 1, the supply discharge pump is to be supplied to the grass. When activated, the water flows into the pipe through the main supply discharge pipe, and the water flowed into the branch pipe supplies water to the grass through the branch pipe. After opening the discharge valve and driving the supply discharge pump in reverse, it can be seen that a device for discharging the accumulated water into the suction discharge pipe of the branch pipe is discharged to the outside through the supply discharge pipe and the main supply discharge pipe.

1 and 2 showing the prior art of the prior art 1, the supply line 17 and the four water supply line 15 is installed on the golf course, the main water supply line 15 has a plurality of distribution lines ( 16) is installed to receive the air from the blower through the distribution line it can be seen that it is configured to control the humidity and cooling and heating of the lawn of the course.

As a plurality of aeration subsystems including an air blower unit communicating with each other, a vacuum is not generated in the vacuum mode of the aeration conduit and the aeration conduit so that the air circulation is prevented. There is a problem that is not made smoothly. In other words, an error occurs in the process of signaling between the intermittent vacuum mode operation and the intermittent pressure mode operation and selectively on / off cycles, so that the turf of the golf course is not managed smoothly. There is a problem.
