Description

Powerless irrigation and nutrient solution for pot cultivation {FERTIGATION APPARATUS OPERATABLE WITHOUT POWER FOR POT CULTIVATION}

The present invention relates to a pot cultivation method, and more particularly, to a non-powered irrigation and nutrient solution for pot cultivation that allows for continuous watering and nutrient solution to the pot without the consumption of electrical or mechanical energy in one supply.

In the face of unemployment, such as layoffs due to the recession and fewer new employees, new job creation is required. Development policies are necessary in that they increase such job creation, but they can also accelerate pollution and global warming. For example, solar, wind, tidal, etc. are spotlighted as an alternative to fossil fuels, but large-scale development is inevitable, and astronomical costs are required for development. This problem can be solved to some extent by the Clean Development Mechanism (CDM) project.

On the other hand, city residents living in asphalt and concrete buildings are urgently needed to expand green spaces for rest and dialogue. Pot Cultivation, through proper watering and fertilization, induces greening in a very low cost and eco-friendly way even under conditions such as asphalt, concrete, and reclaimed land, where growth conditions are difficult to meet. Securing carbon credits by securing green spaces, reducing cooling power in urban areas in the summer and preventing overloads of electricity, rest in green spaces, and improving the living standards of urban residents through industrial activities.

As a pot-grown crop, canopy and ornamental landscaping plants with small leaf areas are not affected by the growth of small amounts of water once every few days or weeks. However, water pipes and fruit trees with large leaf areas, such as grapes and rapeseed, are crops capable of providing a shade area of 10 m 2 or more per week, and must be flooded with a large amount of water (more than 3 l / day) several times a day. .

In large-scale cultivation, it is easy to supply water with a timer-type water pump, but when cultivating in small-scale at home, work, and market, such a mechanical irrigation device is rather cumbersome and expensive. In addition, depending on the growing situation, a large amount of fermentation is required (eg, fruiting, non-atmosphere, etc.), which requires immediate and sufficient control of fermentation.

In order to solve the above problems, Patent No. 10-0981598 discloses that the valve seat is formed in the water tank, the opening of the valve seat is closed by the movable member under elastic force, and the movable member is connected to the plotter to open and close the opening. A non-powered irrigation and nutrient solution is disclosed. However, when the valve seat is formed in the water tank, it is difficult to form a valve, and a spring for providing an elastic force has a disadvantage of being easily oxidized in water. In addition, the valve is disposed in the water tank to hinder the flow of water, the moving member is connected to the plotter has a problem that the movement of the moving member is completely dependent on the buoyancy of the plotter.

The present invention has been made in view of the above, the supply of water or nutrient solution is more smooth, and through a simpler configuration to provide a non-powered irrigation and nutrient solution apparatus that can induce greening at low cost without using power have.

In order to solve the above problems, the non-powered irrigation and nutrient solution associated with the present invention is provided with a recessed groove that can be water or nutrient solution and the bottom of the port is formed so that the surface can be submerged in the water surface, the bucket is to be seated A water tank holder configured to be able to connect with the water tank holder and the port seating portion, a valve body mounted to the water tank and forming an outlet of the water tank through the through hole, and disposed in the through hole and disposed outside of the water tank. And a valve unit having a moving member formed to open the discharge port by moving in a direction, and a water level adjusting unit configured to control opening and closing of the valve unit to maintain a constant level of the stag groove. In addition, the water level control unit, a floater formed to float on the surface of the water or nutrient solution accumulated in the pool groove, one end is fixed to the floater, the other end is rotatably connected to the valve body, the plotter is a reference When the float rises above the water level, the movable member supports the movable member between both ends so that the movable member moves in the direction of blocking the outlet, and the distance of the movable member to limit the distance that the movable member is moved outwardly of the water tank. And a stopper disposed on the rotation path.

In addition, the valve body is disposed to penetrate the bucket, the outer peripheral surface of the valve body is formed with a circumferential projection to be seated on one surface of the bucket, a sealing member is disposed on the circumferential projection to seal the through portion of the bucket, A tightening member may be mounted on an outer circumferential surface of the valve body so that the valve body is caught by the other surface of the bucket.

In addition, the through hole includes a main through hole formed in the longitudinal direction of the valve body and the movable member is slidable, and an auxiliary through hole extending from the outer surface of the valve body to the main through hole. The member may be formed to open and close the auxiliary through hole.

In addition, a support member for supporting the plotter in the buoyancy direction of the plotter may be disposed in the bore groove to reduce the moment applied to the operating member when the plotter floats above the reference level.

According to the non-powered irrigation and nutrient solution associated with the present invention, irrigation can be continuously performed without additional supply for a certain period of time only with a single water supply for an orchard tree requiring several times of watering in one day.

In addition, since water supply and interruption are made only by gravity and water pressure, a spring that is easy to oxidize in water is not necessary, thereby realizing more eco-friendly powerless watering and nutrient solution.

In addition, according to the present invention through the auxiliary through hole, it is possible to continue watering when the outlet is blocked by foreign matters. In addition, the moment applied to the operating member through the support member for supporting the floater in the buoyancy direction is reduced, and further, external impact on the floater, the operating member, etc. during the reverse flow of water can be alleviated.

2 and 3, the non-powered irrigation and nutrient solution device 150 is mounted with a pot 110 and a bucket 120 in which the crop 101 is planted. In terms of placement, these ports 110 and buckets 120 may be disposed adjacent to each other or may be disposed apart over a distance. In addition, the bucket 120 may be formed in a shape that can surround the port 110. As such an example, the bucket 120 may be a 'b' shape, 'b' shape, or a completely enclosed shape such as a donut.

The port 110 is formed to have a space to fill the top soil, but the bottom surface has a plurality of through holes 112 to absorb the water supplied from the bottom. The first rock surface layer 171 disposed horizontally may be disposed on the bottom surface of the port 110 so as to increase water absorbency, and the second rock surface layer 172 disposed vertically is disposed on the sidewall. A plurality of second rock surface layers 172 may be formed along the sidewall of the port 110 in the circumferential direction. Rock wool of such rock wool layers is very useful in terms of recycling of resources and pollution prevention, because it can use waste of building materials or industrial materials.

According to Figure 2, the non-powered irrigation and nutrient solution device 150 includes a frame 151, the frame 151 is a port seating portion 152 and the water tank 120 for mounting the port 110 as described above It includes a bucket holder 153 that can be seated. The bucket holder 153 is formed in a groove shape so that water or nutrient solution flowing out from the mounted valve device of the bucket 120 may be primarily accumulated.

The port seating portion 152 also includes a pooling groove 154 where water or nutrient solution may accumulate. Water or nutrient solution filled in the chamfering groove 154 is formed so that the water level of the bottom surface of the port 110 can be locked.

The port seating portion 152 and the bucket holder 153 are connected to each other by the communication passage 155. The communication passage 155 may be formed directly on the frame 151 as shown in FIG. 2, or may be formed in the form of a hose or similar pipe means connecting the port seating portion 152 and the water tank holder 153 as another example. . As such, the water collected in the bucket holder 153 is moved to the port seating portion 152 and is accumulated, and the water accumulated in the port seating portion 152 is absorbed through the bottom surface of the port 110 that is in contact with the water surface. do.

The watering and nutrient solution device 150 includes a valve unit 130 and a water level control unit 140, the water of which the port 110 is accumulated in the pool groove 154 of the port seating portion 152 by a combination thereof Or it is made to maintain a constant level of nutrient solution.

Referring to FIG. 3, the valve unit 130 is formed at the bottom of the bucket 120. The valve unit 130 includes a valve body 131 and a moving member 132.

The valve body 131 is disposed to penetrate the lower portion of the bucket 120, and is formed to be detachable from the bucket body 121. However, the present invention is not necessarily limited thereto, and may be disposed at another position of the bucket 120 or may be directly formed on the bucket body 121.

The valve body 131 may be formed of a material that does not rust in water such as, for example, a synthetic resin or an alloy. In addition, the valve body 131 is formed in a circular shape, the upper portion may be inclined in a direction in which the diameter gradually decreases so as to have less influence on the hydraulic pressure.

The valve body 131 has a through hole 133 formed therein. That is, the valve body 131 forms a discharge port 134 through which the water or medicine is discharged from the bucket 120 through the through hole 133.

The moving member 132 is disposed in the through hole 133 and one end of the moving member 132 blocks the outlet 134. More specifically, one end of the moving member 132 is located in the through hole 133 so as to be sealed with one end of the through hole 133 (one end of the shape surface of the through hole).

According to this structure, there is no element that prevents the flow of water or nutrient solution flowing into the outlet 134 in the bucket 120, the water or nutrient solution can be more smoothly supplied.

One end of the moving member 132 and one end of the through hole 133 may be formed of inclined surfaces corresponding to each other to increase the contact area. In addition, a soft member (not shown) such as rubber or silicone rubber may be mounted at one end of the moving member 132 to provide a strong sealing force by contact with one end of the through hole 133.

The moving member 132 is formed to be able to open the outlet 134 by moving in the outer direction of the bucket (120). The moving member 132 is generally moved in the direction of opening the outlet 134 by the water pressure of the bucket 120, it may be made of an appropriate weight so as to easily move even when the water pressure of the bucket 120 is weak. As an example of such a moving member 132, the moving member 132 may be a needle valve.

According to the illustration, the other end of the movable member 132 (the opposite end of the end blocking the discharge port) is located outside the through hole 133. The other end of the moving member 132 is supported by the water level control unit 140, and the moving member 132 can be moved between the state of blocking and opening the outlet 134 through the position change of the support point.

The water level control unit 140 is configured to adjust the opening and closing of the valve unit 130 to maintain a constant level of the pool groove 154. More specifically, the water level control unit 140 presses the moving member 132 to open or close the outlet of the bucket 120, thereby adjusting the water level of the water or nutrient solution accumulated in the pool groove 154 through the port ( The bottom surface of 110) should be locked to a certain depth.

For example, the water level adjusting unit 140 includes a plotter 141, an operation member 142, and a stopper 143.

Plotter 141 is formed to float on the surface of the water or nutrient solution accumulated in the pool groove 154. The plotter 141 may be formed by a hollow body or a resin material having a low density, and floats along the surface of the pool groove 154 or descends when the surface is lowered.

According to Figure 3, the plotter 141 is made to apply a rotational force to the operating member 142. More specifically, one end of the operating member 142 is fixed to the plotter 141, the other end is rotatably connected to the valve body 131. As an example of being rotatably connected to the valve body 131, the other end of the operating member 142 may be pivotally coupled to the valve body 131.

A lower protrusion 135 formed of a hollow body is formed below the valve body 131. The operation member 142 is pivotally coupled to one side wall of the lower protrusion 135 and extends toward the recess 154 through the opening formed in the other side wall of the lower protrusion 135.

The operating member 142 supports the moving member 132 between both ends so that the moving member 132 moves in a direction of blocking the outlet 134 when the plotter 141 floats above the reference level. Support points of the operating member 142 and the moving member 132 is formed in the hollow portion of the lower protrusion 135.

According to this structure, the operating member 142 rotates counterclockwise around the pivot 144 when the plotter 141 descends along the water surface, and on the contrary, the operating member 142 when the plotter 141 is raised. ) Rotates clockwise about the pivot 144.

When the operating member 142 rotates in the counterclockwise direction, the support points of the operating member 142 and the moving member 132 retreat and the valve unit 130 is opened. In contrast, the operating member 142 rotates in the clockwise direction. The member 142 pushes the movable member 132 to close the valve 130.

Water or nutrient solution stored in the bucket 120 by the action of the water level control unit 140 is to maintain a constant level in the pool groove 154 of the port seating portion 152. Therefore, the water supplied in the port 110 can be continuously managed unattended according to the state of the port 110. In addition, since the water level adjusting unit 140 opens and closes the valve unit 130 only by gravity and water pressure, a more environmentally friendly powerless irrigation and nutrient solution can be realized.

Referring to FIG. 3, a stopper 143 is disposed on a rotation path of the operation member 142 to limit the distance that the moving member 132 is moved outwardly of the water tank 120. The stopper 143 is disposed in the opening of the lower protrusion 135 and protrudes in a direction perpendicular to the operating member 142 to limit the rotation of the operating member 142.

Through this, when there is no water or nutrient solution in the sloping groove 154 for the initial installation of the bucket 120 or the cleaning of the spool groove 154, the moving member 132 is separated from the through hole 133 Can be prevented.

Referring to the valve unit 130 with reference to FIG. 3 again, a circumferential protrusion 136 is formed on the outer circumferential surface of the valve body 131 so as to be seated on one surface of the water tank 120, and the through portion of the water tank 120 is a shiring. The ring member 137 is disposed on the circumferential protrusion 136. The shiring member 137 may be, for example, an O-ring.

According to the illustration, the tightening member 138 is mounted on the outer circumferential surface of the valve body 131 so that the valve body 131 is caught on the other surface of the water tank 120 (opposite side of the surface on which the circumference is seated). For example, a thread is formed on the outer circumferential surface of the valve body 131, and the fastening member 138 may be a nut coupled thereto.

Figure 4 is a cross-sectional view showing another example of the non-powered irrigation and nutrient solution associated with the present invention, Figure 5 is an enlarged view of portion A of FIG. The non-powered irrigation and nutrient solution device 250 shown in FIGS. 4 and 5 includes further technical principles for maintaining a constant level of water or nutrient solution supplied to the port 111.

According to the figure, the through hole 233 in the valve body 231 includes a main through hole 233a and an auxiliary through hole 233b.

The main through hole 233a is formed in the longitudinal direction of the valve body 231 and is disposed in the main through hole 233a such that the movable member 232 is slidable. That is, the main through hole 233a is similar to the through hole 133 (see FIG. 3) in the embodiment described with reference to FIG. 3.

The auxiliary through hole 233b is formed to extend from the outer surface of the valve body 231 to the main through hole 233a. The auxiliary through hole 233b mainly serves to enable watering even when the outlet 234 is clogged by foreign matter. More specifically, the auxiliary through hole 233b is configured to communicate the inner space of the water bottle 120 and the main through hole 233a.

The moving member 232 is formed to open and close the auxiliary through hole 233b. For example, a rubber protrusion 239a is mounted on an outer circumferential surface of the moving member 232, and the rubber protrusion 239a is a guide groove 239b provided in the main through hole 233a according to the movement of the moving member 232. It slides along. The rubber protrusion 239a may be formed in a ring shape.

The rubber protrusion 239a is configured to be inserted into the inlet of the auxiliary through hole 233b while the moving member 232 blocks the outlet 234 of the bucket 220. Through this, the rubber protrusion 232a may block the entrance of the auxiliary through hole 233b.

In addition, in order to limit the rotation of the movable member 232 in the circumferential direction and guide the sliding movement of the movable member 232 more smoothly, an auxiliary guide groove 239c may be disposed on the opposite side of the guide groove 239b. .

Referring to the drawings, the portion in which the plotter is disposed in the groove 254 is made to open to the outside. For example, when rainwater is filled in the port 110 (see FIG. 2) due to heavy rain or the like, the rainwater may flow back into the recess 254. When rainwater flows back above a certain level, rainwater may flow out through the opened portion.

A support member for supporting the plotter 241 in the buoyancy direction of the plotter 241 so as to reduce the moment applied to the operating member 242 when the plotter 241 floats above the reference level. 262 is disposed.

Support member 262, for example, is made to support the upper portion of the plotter 241 at a specific point, and is mounted on the port seating portion (152, see Fig. 3) or the bucket holder 253 or the bucket holder 253 and It can be formed integrally.

For example, when rainwater or the like flows back into the trap groove 254, the level of the pool groove 254 continues to increase, thus increasing the force applied by the plotter 241 to the operating member 242. An increased bending moment M may occur in the actuating member 242 due to the increased force, which weakens the durability of the actuating member 242.

As the supporting member 262 supports the upper portion of the plotter 241 at a certain point, the moving member 232 blocks the outlet 234 of the bucket 220 and continues to increase the water level of the holding groove 254. In this case, the buoyancy of the plotter 241 is canceled, and external shocks to the plotter 241 and the operation member 242 may be alleviated.

As described above with reference to the drawings illustrating a non-powered irrigation and nutrient solution for pot cultivation according to the present invention, the present invention is not limited by the embodiments and drawings disclosed herein. At least one or more of the disclosed embodiments may be combined, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention.
