Description

Plant hydroponic cultivation system {PLANT HYDROPONIC SYSTEM}

The present invention relates to a plant hydroponic cultivation system. More specifically, a cultivation container containing plant seeds is placed on the first layer of a multi-layer carrier chain and transported to the upper layer, and the cultivation container grown while being transported from the upper layer to the lower layer is placed on the first layer of a multi-layer carrier chain. It relates to a plant hydroponic cultivation system in which the germinated cultivation container is placed back on the transport chain after recovery from the same location.

In general, the method of growing plants in a nutrient solution made of water and water-soluble nutrients without using soil is called hydroponics. Hydroponic cultivation, which was used only for special purposes in the past, is now spreading to a variety of plants as interest in eco-friendly, pesticide-free cultivation increases.

Especially in the case of hydroponic cultivation, because soil is not necessary, a hydroponic cultivation device called a "plant factory", which installs a plurality of hydroponic cultivation plates in a double layer so that the roots come into contact with the culture medium and the plants grow, has been proposed.

At this time, when installing a hydroponic cultivation panel with seedlings planted or retrieving fully grown plants, a person moves directly to the location of the hydroponic cultivation plate and performs the work, and accordingly, all space must be prepared for installation and recovery work. There is a downside to this.

Additionally, there is the inconvenience of workers having to move with the hydroponic cultivation plate for installation and recovery.

In order to improve these shortcomings, a cultivation system was developed that arranges the work space along the waterway along which the hydroponic cultivation plate moves, which is Korean Patent No. 10-0897795. However, the waterway where the hydroponic cultivation plate is located is long during the long period of cultivation. Therefore, it has the disadvantage of requiring a very large space.

In addition, during the process of installing and recovering hydroponic cultivation plates in multiple waterway members, workers can be positioned in place, solving the problem of low space utilization. And during the installation process, you can create space by pushing the installed hydroponic cultivation board.

This conventional technology has a problem in that it is composed of a single layer type, making it difficult to cultivate in large quantities, resulting in a significant drop in productivity.

Meanwhile, in the retrieval process of Republic of Korea Patent No. 10-1311210, a configuration has been developed in which a hydroponic cultivation panel from a distant location is moved toward the worker by pulling a lead wire, but this has the disadvantage of requiring the operator to move the hydroponic cultivation panel directly, which results in a multi-layered arrangement. Because there are limits to what it can do, it is unfortunate that the use of the synopsis is not high.

Republic of Korea Patent No. 10-0897795 (registered on May 8, 2009) Republic of Korea Patent No. 10-1311210 (registered on September 16, 2013)

In order to solve the problems of the prior art as described above, the present invention places a cultivation container containing plant seeds on the first layer of a double-layered transport chain and transports them to the upper layer, and transports the cultivation containers grown during transportation from the upper layer to the lower layer in the same manner. After being recovered from the location, the germinated cultivation container is placed back on the transport chain to provide a plant hydroponic cultivation system with a new structure that can use space efficiently.

This is a conceptual diagram showing the concept.

As shown in Figures 1 and 2, the plant hydroponic cultivation device 10 according to an embodiment of the present invention includes a transport part 100, a transport roller part 200, a sub-roller part 300, and a drive part 400. and a water receiving unit 500.

More specifically, as shown in FIGS. 1 and 2, the hydroponic plant cultivation device 10 according to an embodiment of the present invention includes a carrier extending longitudinally inside the housing 11 and formed continuously in multiple layers. 110, a cultivation container 12 containing plant seeds is seated, and a plurality of transport parts 100 are connected to the lower part of the transport chain 110 along the extending direction of the transport chain 110, the transport part A transport roller unit 200 and a transport chain 110 that connect the transport chain 110 in an up and down zigzag shape on both sides of the transport direction of 100 to transport the cultivation container 12 from the first floor to the n-th floor. It is provided with a sub-roller unit 300 that extends on one side and is connected at least two times between the first to n-th layers to apply tension to the transport chain, and a drive motor that connects the transport roller unit located on the other side with a chain and rotates it. A water receiving unit 500 is disposed at the lower part of each layer of the driving unit 400 and the transport unit 100 arranged in multiple layers and rises and falls to submerge the cultivation vessel 12 and administer the nutrient solution to the plant seeds. Includes.

Referring to Figures 1 and 2, the transport unit 100 is formed of one transport chain 110 continuously extending from the first layer to the n-th layer, and the transport chain 110 is connected from the first layer to the n-th layer. It is arranged up and down to form a double layer.

Here, the transport chain 110 is formed as a pair spaced apart from each other corresponding to the length of the cultivation container 12. In addition, when arranging up and down, transport roller units 200 are installed on both sides and move by rotation of the transport roller units 200.

In addition, it is preferable that the transport chain 110 is arranged vertically at an interval equal to the diameter of the transport roller unit 200 to prevent vertical interference with the seating plate 120, which will be described later.

Referring to FIGS. 2 and 3 , the transport unit 100 further includes a seating plate 120, a support stand 130, and a shaft portion 140.

The seating plate 120 is formed as a plate on which the cultivation container 12 is seated, and is arranged in plural pieces at regular intervals along the length of the transport chain 110.

The support 130 is a frame extending vertically from both sides of the seating plate 120 and has a predetermined length.

In particular, the upper end of the support 130 is located inside the transport chain 110 and moves in response to the movement of the transport chain 110, thereby transporting the seating plate 120. And when positioned on the transport roller unit 200, the seating plate 120 is positioned on the inner surface of the rotating reel 210 forming the transport roller unit 200.

Referring to Figures 2(b) and 3, the shaft portion 140 is formed by spacing any one of bearings, gears, chains, and protruding shafts at regular intervals along both sides of the transport chain 110 in the longitudinal direction.

In particular, the shaft portion 140 is rotatably coupled to the upper part of the support 130, so that when the transport chain 110 of the first layer moves to the n-th layer, the support 130 is rotated in the vertical direction to form the seating plate 120. It serves to enable it to be positioned in the horizontal direction.

For example, the upper part of the support 130 is coupled to the shaft portion 140 on the inside of the transport chain 110 provided as a pair, facing each other along the longitudinal direction and being spaced apart. Then, the cultivation container 12 containing the plant seeds is placed on the seating plate 120 coupled to the lower part of the support 130, and then the transport chain 110 is moved.

At this time, the support 130 rotates in the direction of gravity with respect to the shaft 140 due to the inclination angle of the transport chain 110 and is positioned in the vertical direction. Due to this, the seating plate 120 is also positioned at a right angle with respect to the lower part of the support 130 and is positioned in the horizontal direction.

Therefore, when the cultivation container 12 located on the upper surface of the seating plate 120 passes through the transfer roller unit 200 or is transferred from the first layer to the nth layer, it is not deflected in any direction or falls from the top to the bottom. do.

Meanwhile, in the hydroponic plant cultivation device 10 according to an embodiment of the present invention, the transport unit 100 further includes a steel rod 160.

The steel rod 160 is formed as a frame extending in the longitudinal direction, and both sides are coupled to the wall of the housing 11 or a partition frame 11a supporting both sides of the housing 11 in the longitudinal direction.

This steel bar 160 supports the lower part of the transport chain 110 and prevents the transport chain 110, which moves in a straight direction, from sagging downward.

In addition, as shown in FIGS. 1 and 6, an LED module (L) is provided at a distance from the upper part of the transport chain 110 to grow germinated plant seeds.

In particular, the seating plate 120 moves along the carrier chain 110 formed continuously from the first to the n-th layer and then moves from the n-th layer to the first layer. During this moving time, it is desirable to grow germinated plant seeds with an LED module (L).

Referring to Figures 1 and 3, the transport roller unit 200 serves to transport the cultivation container 12 from the first floor to the n-th floor by connecting both sides of the transport unit 100 in an up and down zigzag manner.

That is, the transport roller unit 200 is rotatably connected to the other side of the transport chain 110 located on the first layer, and the other side of the transport chain 110 has a height of the second layer equal to the diameter of the transport roller unit 200. It is located in and extends to one side.

At this time, the transport roller unit 200 is rotatably connected to one side of the transport chain 110 located on the second layer, and one side of the transport chain 110 has a height of the third layer equal to the diameter of the transport roller unit 200. Located in and extending to the other side, the transfer roller unit 200 is arranged up and down in a zigzag direction up to the nth layer.

This transfer roller unit 200 further includes a rotating reel 210 and a drive belt 220.

The rotating reel 210 is formed as a plate that is axially connected to the inner wall of the housing 11 and rotates. Then, the transport chain 110 contacts and connects to the outer peripheral surface of the plate.

In particular, the rotating reel 210 has a shaft that penetrates the center, and the shaft protrudes to the outer surface of the housing 11. And the axis of the rotating reel 210 protruding to the outside of the housing 11 is coupled to the bracket.

The drive belt 220 is a belt connected on one side to the drive unit 400 and on the other side connected to a rotating reel 210 located on the other side of the transport unit 100.

This drive belt 220 moves the transport unit 100 by rotating the rotary reel 210 by driving the drive unit 400. One side is connected to the drive motor located at the top of the housing 11, and the other side is connected to the drive motor located at the top of the housing 11. It is connected to a shaft formed on one of the rotary reels 210 and rotates the rotary reel 210 by rotation of the drive motor.

Due to this, the carrier chain 110 connected to the rotating reel 210 moves and circulates from the first to the nth layers.

Referring to Figures 1 and 4, the sub-roller unit 300 extends one side of the transport chain 110 and is connected at least two times between the first to nth layers to apply a tensile force to the transport chain 110. It plays a role.

To this end, the sub-roller unit 300 further includes a sub-rotating reel 310, a moving shaft unit 320, and a fixed rotating reel 330.

The sub-rotating reel 310 is located on one side of the transport unit 100 and is formed as a plate that is axially connected to the inner wall of the housing 11 and rotates.

The moving shaft unit 320 is a frame that is connected to both sides of the sub-rotating reel 210 and moves the sub-rotating reel 210 in a straight line back and forth a predetermined distance.

That is, one side of the moving shaft portion 320 is connected to the inside of the housing 11 and the other side is connected to a shaft formed in the center of the sub-rotating reel 210.

For this purpose, the moving shaft portion 320 is made of a cylinder whose length is contracted by hydraulic pressure, and the end of the cylinder is connected to the shaft of the sub-rotating reel 210.

In addition, it is desirable to form a guide rail in the housing 11 in response to the linear reciprocating movement of the moving shaft portion 320 so that the axis of the sub-rotary reel 210 can linearly reciprocate along the guide rail.

In this way, the moving shaft unit 320 moves the sub-rotating reel 210 in a straight line, thereby applying a tensile force to the transport chain 110 connected to the sub-rotating reel 210, so that the transport chain 110 becomes loose or moves downward. This is to prevent sagging.

The fixed rotating reel 330 is located on one side of the transport chain 110 located on the first layer of the sub-rotating reel 310 and serves to firmly position the height of the transport chain 110.

Referring to FIGS. 1 and 3, the driving unit 400 includes a driving motor that connects and rotates the transport roller unit 200 located on the other side.

That is, the drive unit 400 is provided with a drive motor at the top of the housing 11, and connects the drive belt 220 to the drive motor to drive the drive motor to rotate the rotary reel 210 connected to the drive belt 220. I order it.

At this time, when one rotary reel 210 located on the other side of the transport unit 100 is rotated, the other rotary reel connected to the transport chain 110 rotates and the transport chain 110 moves from the first to the nth floor. It is circulated.

Referring to Figures 5 and 6, the water receiving unit 500 is disposed at the bottom of each layer of the transport unit 100 and submerges the cultivation vessel 12 and rises and falls to inject the nutrient solution into the plant seeds.

To this end, the water receiving unit 500 further includes a water tank unit 510, a nutrient solution supply unit 520, and a nutrient solution recovery unit 530.

The water tank 510 is open at the top, stores the nutrient solution inside, and extends in the longitudinal direction to accommodate the seating plate 120 connected to the lower part of the transport chain 110 of each layer.

At this time, the water tank units 510 constituting the water receiving unit 500 of each floor are connected together to the cylinder frame 570, which will be described later, and all water tank units 510 rise and fall simultaneously in response to the raising and lowering of the cylinder frame 570. . Due to this, cultivation conditions such as intermittent flow type, wick type, soak type, spray type, etc. can be converted by vertical movement control of the contact time of the nutrient solution to the roots of the plant seeds contained in the cultivation plate 12.

Referring to Figures 5 and 6, the nutrient solution supply unit 520 forms a hole through which the nutrient solution is introduced to one side of the water tank unit 510, and is connected to a hose that supplies the nutrient solution.

The nutrient solution recovery unit 530 forms a hole through which the nutrient solution is discharged in the lower part of the other side of the water tank unit 510, and is connected to the hose of a circulation pump that purifies the discharged nutrient solution and supplies it back to the nutrient solution supply unit 520.

At this time, if the nutrient solution is highly contaminated, it is also possible to discharge it through a sewage treatment process.

In addition, the water receiving part 500 extends upward from the bottom of the other side of the water tank part 510 and forms an overflow prevention wall 540 that is formed lower than the height of the water tank part 510, so that the cultivation container 12 is connected to the water tank part. When received inside 510, it is desirable to allow the nutrient solution to move beyond the overflow prevention wall 540 to the nutrient solution recovery unit 530.

Here, the overflow prevention wall 540 is formed as a partition dividing the other side of the water tank 510 and forms a separate accommodation space together with the water tank 510. And when the nutrient solution overflows and flows into the space, it can be discharged to the outside through the nutrient solution recovery unit 530 in communication with the receiving space or circulated to the nutrient solution supply unit 520.

Meanwhile, in the hydroponic plant cultivation device 10 according to an embodiment of the present invention, the water receiving unit 500 further includes a water level sensor unit 550 and a discharge unit 560.

The water level sensor unit 550 is provided at a position lower than the overflow prevention wall 540 and is formed as a sensor capable of controlling the water level of the nutrient solution flowing into the water tank unit 510.

The discharge unit 560 forms a discharge hole on the other lower surface of the water tank unit 510 to allow the nutrient solution stored in the water tank unit 510 to be discharged to the outside. As a result, foreign matter in the cultivation vessel 12, which repeats the process of being submerged into the water tank 510 several times, is mixed with the nutrient solution and the contaminated nutrient solution is discharged to the outside, allowing clean nutrient solution to flow into the water tank 510.

In addition, as shown in FIG. 6, in the hydroponic plant cultivation device 10 according to an embodiment of the present invention, the water receiving unit 500 further includes a cylinder frame 570 and a hydraulic unit 580.

The cylinder frame 570 is a frame joined to at least two sides on both sides along the longitudinal direction of the water tank unit 510.

That is, it is coupled to both sides of the water tank 510 formed on each floor to firmly support the water tank 510. In addition, the cylinder frame 570 is raised and lowered by the operation of the hydraulic unit 580, and the water tank unit 510 is also raised and lowered, allowing the cultivation container 12 mounted on the seating plate 120 to be submerged.

The hydraulic unit 580 installs a hydraulic pump device on the bottom of the housing 11 and is coupled to the lower part of the cylinder frame 570 to raise and lower the lower part of the cylinder frame 570.

For this reason, when the cultivation container 12 containing plant seeds for hydroponic cultivation is moved from the first to the nth floor and then transferred from the nth floor to the first floor again, the cylinder frame 570 is moved at a predetermined time. By raising and lowering, nutrient solution can be provided to plant seeds.
