The present invention relates to a soil oxygen feeder that not only effectively increases the amount of dissolved oxygen in water provided to the soil, but also directly supplies oxygen into the soil. The present invention relates to a soil oxygen feeder that increases the amount of oxygen by spiraling an inner form of a pipe into which water is injected. It is about

In general, plant growth requires water, oxygen and other gases. Among the various gases required for plant growth, oxygen is the most important gas, and the reason for plowing is to blow air, or oxygen, into the soil. To this end, conventionally, by sprinkling using a sprinkler, a spraying hose, and a dropping hose, air is supplied to the root zone through pores in the soil as water flows into the ground. However, this has many limitations in improving the oxygen demand of plants and the soil three-phase (climate, solid, liquid), that is, the physical properties of the soil. As the ground hardens after raining, the more water is given, the more the soil will pass and the less breathable. The growth state of the root zone of the plant is deteriorating.

On the other hand, the leaves of plants suck carbon dioxide and release oxygen, whereas the roots of plants require oxygen. In addition, if the humidity in the root zone of the plant is maintained for too long, the activity of the microorganisms necessary for food switching is stopped. In addition, too long drying does not form nutrients due to the lack of moisture to help the microorganisms, despite the oxygen in the soil. Therefore, it is good to alternate the wet and dry parts of the root zone of the plant. To this end, the conventional cultivation method is to help the growth of crops by dissolving oxygen dissolved in groundwater or artificially by adding oxygen to the water tank to increase the amount of dissolved oxygen and spraying the water on the plants. However, this conventional method has limitations in increasing the amount of dissolved oxygen as well as in spraying for easy absorption by plants.

The present invention has been made to solve the above problems, by using a Bernoulli principle of the purpose of reducing the diameter of a part of the pipe and to install an air inlet in this part to allow the air and water to be supplied to the soil together. In addition, by the screw spiral portion of the water is injected, it is intended to maximize the oxygen supply by the form of the water to be obtained in the form of a screw. In addition, it is an object to increase the oxygen injection amount by forcibly injecting oxygen to the air inlet using a compressor. Oxygen injection using a compressor is designed to overcome the relationship of spiral soil oxygen supply. In other words, the spiral soil oxygen supply is designed to compensate for the oxygen supply only when water is injected, and is designed to block the water injection valve and forcibly inhale oxygen into the soil with the compressor through the air inlet of the spiral soil oxygen supply.

In order to achieve the above object, the present invention, the air intake portion for receiving air from the outside atmosphere, and the water inlet portion for rotating the screw screw in the water injected from the outside, the inner wall is spiral, the inner penetration radius is the water inlet portion Spiral soil oxygen, which has a narrower structure, increases the flow velocity and includes a compression unit for mixing air sucked from the air intake unit into air bubbles in the water, and an expansion outlet for discharging water from the compression unit to the outside. Suggest a feeder.

Hereinafter, the detailed description of the preferred embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that the same components in the figures represent the same numerals wherever possible.

Storage tank 10 is a device for providing water provided to the soil through the spiral soil oxygen supply 22, the water stored in the storage tank 10 is characterized in that the pump is introduced into the spiral soil oxygen supply (22) Have The pump 12 is a device for controlling the amount of water provided to the underground drop tape 28, wherein the pressure of the pump 12 depends on the total length of the underground drop tape 28, but the underground drop tape 28 Is 1000m ~ 4000m, the rolling of 2-3 horsepower is suitable. The shape of this drop tape 28 is shown in FIG. The filter 14 removes the foreign matter that may be in the water and provides the water without the foreign matter to the spiral soil oxygen supply. The primary pressure gauge 16 and the secondary pressure gauge 24 are devices for controlling the pressure of the water so that the primary pressure gauge 16 has a pressure of 2K to 3K and the secondary pressure gauge 24 has a pressure of 0.5K to 1.5K. desirable. The liquid fertilization injection 18 is a device for injecting liquid fertilizer and microorganisms, and injects air as usual and performs a function of injecting fertilizer and microorganisms as necessary. In other words, nutrients are supplied directly to the root zone to maximize efficiency. The valve 20 performs an operation of a regulating device that regulates the flow of incoming water. The main water pipe 26 serves to supply water to the underground drop tape 28 as a PE pipe or a PVC pipe. The underground drop tape 28 is embedded in the soil to perform the function of evenly providing the soil with water and oxygen provided from the spiral soil oxygen supply 22. The depth in which the underground drop tape 28 is embedded in the soil may be applied differently depending on the type of plant, and is generally formed at about 6 to 15 centimeters on the ground surface. The water provided to the soil in the ground drop tape 28 has a high dissolved oxygen amount by the spiral soil oxygen feeder.

The spiral soil oxygen feeder 22 is composed of a water inlet, a compression, an expansion outlet, and an air inlet. The water absorbed through the water inlet is discharged through the expansion outlet due to a high flow rate, and is then discharged through the water supply pipe. Is passed to The speed of the water absorbed through the water inlet is increased because the Bernoulli's principle speeds up the flow of water through the narrow tube of the compression section. The air intake unit absorbs air from the atmosphere and injects air together with water passing through the compression unit. The air intake unit may intake air from the atmosphere, but may be configured to be connected to an air pressurizer such as a compressor to inject air of a certain intensity to smoothly inhale air. On the other hand, the water inlet is made of a spiral to increase the friction with the air sucked through the rotation of the water. Details of each component of the spiral soil oxygen feeder will be described in more detail with reference to FIG. 2.

Figure 2 is a diagram showing the internal configuration of the spiral soil oxygen supply in accordance with the present invention.

The water injection unit 52 is an injection port through which water from the water storage tank 10 is sucked, and an inner tube wall thereof has a spiral 50. The reason for the spiral 50 inside the pipe is to increase the friction with the air sucked through the rotation of the water. This is because having a spiral structure can cause water to burst momentarily and create a small bubble into which air can enter. In other words, the water that is rotated at a high flow rate is encountered with the sucked air and instantaneous water and air meets the crushing phenomenon occurs to generate a fine bubble. This is because bubbles thus generated are sufficiently small that the bubbles do not coalesce and become large. The microbubbles tend to go with the running water and are thus provided to the root zone of the plant via water pipes and underground drop tapes.

The tube between the water injection section 52 and the compression section 54 has a shape with twisting vanes 72. The twist blades 72 allow the flow of water flowing through the water inlet to be bent at an angle to effectively mix the water from the water inlet and the air from the air inlet. 3 is a front view showing the inside of the tube in the water injection section. By having a structure as shown in Figure 3, it can be seen that the water flow angle can be distorted by a number of twisting vanes (72) present in the tube.

The compression unit 54 is a narrow pipe width of the water so that the flow of water is faster, the water flowing through the water injection unit 52 has an effect that the flow rate is accelerated by the compression unit. This is due to Bernoulli's principle that the narrower the tube, the faster the flow rate.

Air intake 58 is a place where air is sucked, through which a large amount of oxygen is sucked and mixed with water. The air intake 58 can naturally inhale air in the atmosphere and use it, but this oxygen injection has a certain limit depending on the amount of oxygen that enters by entering with water. In order to overcome this limitation, the air is injected using a compressor. In order to increase the efficiency of the oxygen injection amount, oxygen may be forcibly injected using an air pressurizer such as a compressor. In the case of using a compressor, the water injection unit 52 may or may not be separately blocked. In particular, when the compressor is mainly operated has a feature that is operated when the air supply to the water injection portion 52 to block the supply path and try to inject only air. The spiral soil oxygen feeder using this compressor supplies air (oxygen) together with water and stops the water supply when the water required by the plant is supplied, that is, when the plant no longer needs water. By supplying air (oxygen) using the three-phase (physical properties) of the soil can be maximized. Compressor air injection can repeat the humidity and dryness in the soil with a short term, thus creating a good environment for plant growth. Soil oxygen injection with a compressor can increase yields by approximately 17% to 29% compared to conventional practices. Soil oxygen injection with compressors produced many fine roots in the plant root zone, and the root zone development affected stems and leaves and eventually linked to increased yields.

The expansion outlet part 56 discharges the water having a faster flow rate through the compression part 54 to the main pipe. The water flowing out through the expansion outlet 56 is not only faster than the flow rate of the water flowing into the water inlet, but also has the feature that the air sucked from the air intake 58 is mixed with the water in the compressor and outflow. The cross-section of the expansion outlet 56 is shown in FIG. 4, which, like the cross-section of the water injection section (FIG. 3), has straightening vanes 74 in the form of twisted wings, so that water is easily discharged to the outside during discharge. It has a structure to make it possible.

On the other hand, the inner tube wall of the spiral soil oxygen feeder water injection unit 52 shown in Figure 2 is characterized in that the spiral 50, as another embodiment of the present invention the inner tube wall of the water injection unit 52 It will be apparent that the spiral 50 may be implemented in a form that is not. That is, it will be apparent that the inner tube wall of the water injection unit 52 may be embodied in the form of a general planar inner tube wall instead of the spiral 50 shown in FIG. 2. This appearance is shown in FIG.
