The housing 51 has a hollow inside and both sides are formed in an open rectangular cylinder shape. The hollow shape is formed in a circular shape along the longitudinal direction of the housing 51. The shape of the housing 51 may be formed in various shapes in addition to the square shown. The liquid rain inlet hole 53 to which the first connecting pipe 20 is connected is formed at the upper portion of the housing 51. The liquid rain inflow hole 53 is formed penetrating from the outside of the housing 51 to the inside. A screw thread is formed inside the liquid inflow hole 53. A conventional nipple 29 is installed at the end of the first connecting pipe 20, and the nipple 29 is screwed into the liquid non-inlet hole 53.

Next, two vent holes 54 and 55 are formed next to the nutrient solution inlet hole 53. The distance between the first vent hole 54 and the second vent hole 55 coincides with the left and right movement amount, that is, the displacement of the slider 60. The first and second vent holes 54 and 55 penetrate from the outside to the inside of the housing 51. A thread is formed inside the first vent hole 54. The first vent hole 54 is connected to the vent pipe 1. A conventional nipple 5 is installed at the end of the vent pipe 1, and the nipple 5 is screwed into the first vent hole 54. The vent pipe 1 extends upwards, and preferably the upper end extends higher than the liquid tank 10. The upper end of the vent pipe 1 is exposed to the atmosphere to maintain the pressure inside the slider 60 at atmospheric pressure so that the liquid ratio can easily flow into the interior of the slider 60.

The slider 60 is installed to be slidably movable inside the housing 51. The slider 60 is reciprocated from side to side in the housing 51 by an interruption unit. Three mounting grooves are formed on the outer circumferential surface of the slider 60, and each mounting groove is provided with a rubber ring 61 for maintaining watertightness.

Inside the slider 60, a storage chamber 63 formed of a predetermined size of empty space is provided. The storage chamber 63 is formed to extend left and right along the longitudinal direction of the slider 60. The storage chamber 63 receives and stores each liquid rain through the liquid rain inflow hole 53, and the stored liquid rain is discharged into the second connection pipe 27 through the liquid rain flow hole 57.

A first communication port 65 corresponding to the liquid inflow hole 53 is spaced apart from the upper side of the slider 60. A second communication port 67 corresponding to the first vent hole 54 is formed at the left side of the first communication port 65. And the lower side of the slider 60, the third communication port 69 corresponding to the liquid rain outflow hole 57 is provided. In the state where the first communication port (65) coincides with the liquid rain outlet hole (53), and the second communication hole (67) coincides with the first vent hole (54), the third communication hole (69) is a liquid rain outlet hole ( 57) located in the area away from it. In this state, the distance between the third communication port 69 and the liquid rain outlet hole 57 corresponds to the displacement of the slider 60. In this state, the distance between the second communication port 67 and the second vent hole 55 also coincides with the displacement of the slider 60.

Therefore, the slider 60 having the above structure is selectively communicated with the liquid-liquid inflow hole 53 or the liquid-liquid outflow hole 57 while reciprocating from side to side by the operation of the intermittent unit. That is, when the slider 60 moves to one side, the liquid inflow hole 53 and the first communication port 65 coincide with each other. Of course, at this time, the first vent hole 54 and the second communication port 67 coincide. When the slider 60 moves in the opposite direction to the above-described direction, the first communication hole 65 is out of the liquid inflow hole 53 by the amount of displacement of the slider 60, and the third communication hole 69 is the liquid rain outlet hole. In line with (57). At this time, the second communication port 67 coincides with the second vent hole 55.

In order to prevent the slider 60 from rotating with respect to the housing 51 during the reciprocating movement of the slider 60, a guide groove 71 is formed on one side of the slider 60 in a lengthwise direction along the moving direction. A stopper 73 is installed in the through hole formed in the housing 51. At this time, the end of the stopper 73 is installed to protrude into the guide groove 71. The stopper 73 may be screwed into the through hole. The length of the guide groove 71 coincides with the length obtained by adding the displacement of the slider 60 and the left and right thicknesses of the stopper 73.

The rod 80 has a screw thread formed on the outer circumferential surface of the head portion 81 to screw the slider 60, and an expansion portion 85 having a larger diameter than the head formed on one side of the head portion 81; The extension part 87 extends to a predetermined length at one side of the extension part 85 and has a diameter smaller than the diameter of the extension part 85. The head portion 81 is provided with a mounting groove 83 is mounted with a rubber ring 84 for maintaining the watertight.

The intermittent unit is connected to the slider 60 by the rod 80 to supply the liquid ratio introduced into the liquid ratio supply unit 50 through the first connection pipe 20 and the second connection tube from the liquid ratio supply unit 50. (27) to control the discharge of the liquid rain outflow.

An example of the intermittent unit is connected to the raw water supply lines 41 and 47 and moves the slider 60 to one side by the pressure of the raw water supplied from the raw water supply lines 41 and 47 to store the storage chamber 63. ) And the liquid fertilizer outlet hole 57 is connected to the actuator 90 to discharge the liquid to the second connecting pipe 27, and if the hydraulic pressure acting on the actuator 90 is reduced, the slider 60 It is provided with a return unit 100 which moves to the side to connect the storage chamber 63 and the liquid rain inlet hole 53 to introduce the liquid rain into the storage chamber (63).

In the present invention, the actuator 90 uses the raw water supplied through the raw water supply line 41 as the working fluid. The actuator 90 is coupled to the protrusion 58 formed to protrude on one opened side of the housing 51, the cylinder 95 having the raw water inlet hole 91 and the raw water outlet hole 93, and the cylinder ( 95 is provided in the interior of the rod (80) is provided with a piston 97 is screwed with the extension bar (87) in communication with the slider (60). A rubber ring 98 for watertightness is mounted on the outer circumferential surface of the piston 97, and one side of the piston 97 is formed with a screw groove 99 that is screwed with the rod 80.

Four corners of the cylinder 95 are formed through the insertion hole 96 through which the bolt 92 is inserted, and the bolt 92 mounted in the insertion hole 96 is formed around the protrusion 58 of the housing 51. Screwed to the screw holes (not shown) formed in each. A rubber ring 59 is installed on an outer circumferential surface of the protrusion 58 inserted into and coupled to one side of the cylinder 95.

The raw water supply lines 41 and 47 are connected to the raw water inlet hole 91 and the raw water outlet hole 93. Specifically, the raw water supply lines 41 and 47 connect the raw water supply unit and the cylinder 95. It is divided into a first raw water supply line 41 and a second raw water supply line 47 connecting the cylinder 95 and the cultivation body 30. The first raw water supply line 41 is provided with a solenoid valve 43 and an accumulator 45 for opening and closing the flow path. The solenoid valve 43 is controlled by the controller 110. The control unit 110 uses a conventional controller. In addition, the control unit 110 receives the water level information from the water level sensor 35 installed in the cultivation body 30 to control the opening and closing of the solenoid valve 43.

The raw water inflow hole 91 is formed at one side of the cylinder 95, and the raw water inflow hole 93 is formed at the lower portion of the cylinder 95. Preferably, the raw water outlet hole 93 is formed to a smaller diameter than the raw water inlet hole (91). This is to allow the raw water to be discharged through the raw water outlet hole 93 while pressing the piston 97 by the pressure of the raw water introduced through the raw water inlet hole 93. In a state in which raw water does not flow through the first raw water supply line 41, the raw water outlet hole 93 is blocked by the piston 97. When the raw water is introduced through the first raw water supply line 41, the piston 97 moves by the pressure of the raw water, and when the piston 97 moves a predetermined distance, the raw water outlet hole 93 is opened. In addition, a third vent hole 94 is formed in an opposite direction in which the raw water inlet hole 91 is formed with the piston 97 interposed therebetween. The third vent hole 94 is exposed to the atmosphere.

The return unit 100 moves the slider 60 sliding to the left by the actuator 9 to the right to return. Here, the return means that the first communication port 65 of the slider 60 moves to coincide with the liquid inflow hole 53 of the housing 51. As an example of the return portion 100 is installed on the extension bar 87 of the rod 80, one end is supported by the housing 51 and the other end is supported by the piston 97 to the elastic member to apply an elastic force to the piston 97 Is done. Compression spring 105 is used as the elastic member. The compression spring 105 is set by the actuator 90 when the piston 97 is moved to the maximum displacement, the elastic force stored in the compression spring 105 is set lower than the hydraulic pressure acting on the piston 97. The compression spring 105 returns the piston 97 by applying an elastic force to the piston 97 when the inflow of raw water into the cylinder 95 is stopped. When the piston 97 returns, the slider 60 also returns.

In the present invention, when using a water supply pipe supplied with a constant pressure to the raw water supply unit, there is no need for a separate pump for applying pressure to the working fluid for operating the actuator 90, because it uses water as the working fluid No pollution, easy maintenance and low cost.

Hereinafter, the operation state of the nutrient solution feeder which is a component of the nutrient solution cultivation apparatus of the present invention will be briefly described.

When the water level sensor 35 detects that the nutrient solution stored in the base 120 of the cultivation body 30 is at a high water level, the solenoid valve 43 is controlled by the control unit 110 to supply the first raw water supply line 41. In the closed state of the flow path, the slider 60 is kept moved to the right in the housing 51 by the elastic force of the compression spring 105. In this state, the first communication ports 65 are connected to each other in coincidence with the liquid inflow hole 53. In addition, the first vent hole 54 is also interconnected with the second communication port (67). Therefore, the liquid rain flows into the storage compartment 63 of the slider 60 from the liquid fertilizing tank 10 through the first connecting pipe 20 and is stored.

Then, when the water level sensor 35 detects that the water level of the nutrient solution stored in the base unit 120 of the cultivation body 30 is below a certain level and is at a low water level, the controller 110 controls the first raw water supply line 41. ) Open the solenoid valve (43) installed. When the first raw water supply line 41 is opened in this way, the raw water supplied at a predetermined pressure from the raw water supply part flows into the cylinder 95. Raw water introduced into the cylinder 95 pressurizes the piston 97, and the piston 97 moves to the left.

As the piston 97 moves to the left side, the first communication port 65 is released from the liquid inflow hole 65. And the piston 97 is moved and stopped by the displacement set by the stopper 73. In this state, the third communication port 69 is connected to the liquid rain outlet hole 57 in correspondence. In addition, the second communication port 67 is connected to the second vent hole 55. Therefore, the liquid rain stored in the storage chamber 63 is introduced into the base portion 120 of the cultivation body 30 through the second connecting pipe 27 to the liquid rain discharge hole 57. At the same time, as the piston 97 moves inside the cylinder 95, the raw water outlet hole 93 is opened, and some of the raw water introduced into the cylinder 95 is discharged into the raw water outlet hole 93 to supply the second raw water supply line. The nutrient solution mixed with the liquid ratio and the raw water is stored in the nutrient solution storage space 123a of the base part 120 by being introduced into the base part 120 of the cultivation body 30 through the 47.

When the liquid level in the storage chamber 63 is all leaked out and the water level sensor 35 detects that the nutrient solution stored in the base portion 12 of the cultivation body 30 is higher than a predetermined level and is at a high water level, the controller 110 controls the controller 110. The solenoid valve 43 is closed to stop the inflow of raw water into the cylinder 95. That is, the controller 110 is the base portion 120 of the cultivation body 30 only up to the high water level to detect the nutrient solution mixed with the raw water and a predetermined ratio by leaking only the liquid ratio of the amount stored in the storage chamber (63) Open the solenoid valve 43 to be stored in. When the inflow of raw water is stopped, the piston 97 and the slider 60 move to the right by the elastic force of the compression spring 105 to return. In the returned state, the first communication port 65 is connected to the liquid fertilizing inlet hole 53 again, and the liquid fertilizer flows into the storage compartment 63 of the slider 60 from the liquid fertilizing tank 10 through the first connecting pipe 20. do.
