Hydroponics growing equipment with detachable bed {Hydroponics growing equipment with detachable bed}

The present invention relates to a hydroponic cultivation apparatus, and more particularly, to a hydroponic cultivation apparatus capable of attaching and detaching a bed to which a port is coupled.

With the recent rise in interest in health, there is a trend to avoid agricultural products using pesticides harmful to the human body in food, and to prefer eco-friendly organic products without pesticides even though they are relatively expensive. In addition, as distrust of imported agricultural products and controversy over the harmfulness of genetically modified agricultural products (GMO) increase, ordinary households are also interested in growing organic products such as vegetables for their own consumption on rooftops, verandas, or indoors. households are increasing.

In response to this, hydroponic cultivation (or nutrient solution cultivation), which uses a simple structured cultivation device and a nutrient solution supply device to grow plants by supplying nutrient solution containing nutrients to plants without using culture soil or using only a small amount if used. ; hydrophonics) method has been developed. Compared to soil cultivation, such hydroponic cultivation not only enables continuous cultivation in the same place for a long period of time, but also yields a constant harvest without a difference in weather conditions. In addition, the environment can be made under the same conditions and the cultivation environment is clean, so fresh and clean crops can be mass-produced throughout the year. In addition, automation of cultivation management is possible, so labor can be reduced, and quality and hygiene are better than crops produced by soil cultivation.

At this time, the nutrient solution shutoff valve 120 coupled to both ends of each bed 110, 110a, 110b, 110c maintains a closed state. Then, the user inserts the port (A) in which the desired plant (B) is planted into the port insertion hole (113) of the bed (110, 110a, 110b, 110c).

The user fixes all the beds 110, 110a, 110b, and 110c to the plurality of bed modules 100, 100a, and 100b in this way, and as shown in FIG. 3, between the bed connectors 210 disposed on both sides of the corresponding floor Insert the bed module (100, 100a, 100b).

The user connects the connector coupling rails 111a and 111b formed at both ends of the plurality of beds 110, 110a, 110b, and 110c coupled to the bed modules 100, 100a, and 100b to the lower rail groove 212a and the upper part of the bed connector 210. Slide and insert according to the rail groove (213a).

At this time, the wing control lever 127 protruding from the top of each bed 110, 110a, 110b, and 110c is inserted along the wing lever moving slit 213c. The nutrient solution control shield 222 coupled to the bed connector 210 is positioned to block the nutrient solution outlet hole 211a, as shown in (a) of FIG.

When all the bed modules 100, 100a, 100b of each floor are coupled to the bed connector 210, the user moves the shield control lever 227 along the shield lever moving slit 213b as shown in (b) of FIG. By moving, the shield 222 opens the nutrient solution outlet hole 211a.

When the nutrient solution outlet hole 211a is opened, the user rotates the wing control lever 127 of each bed 110, 110a, 110b, 110c to open the nutrient solution transfer hole 117 as shown in FIG. open up

As shown in (b) of FIG. 9, when the nutrient solution outflow hole 211a and the nutrient solution transfer hole 117 are opened, the user operates the nutrient solution supply pump 241 to remove the nutrient solution C of the nutrient solution storage tank 240. Through the nutrient solution supply pipe 230, the nutrient solution flows into the nutrient solution outlet hole 211a. Nutrient solution flowing into the nutrient solution outlet hole (211a) flows into the bed (110, 110a, 110b, 110c) through the nutrient solution transfer hole (117) of the bed (110, 110a, 110b, 110c) and through the opposite nutrient solution transfer hole (117). through the bed connector 210 on the opposite side.

In this way, the nutrient solution is moved along the circulation path returning to the nutrient solution storage tank 240 via the plurality of beds 110, 110a, 110b, and 110c, and the port insertion hole ( 113), the plant (B) planted in the port (A) absorbs the nutrient solution and grows.

In this process of plant growth, the user may have to change the position of the beds 110, 110a, 110b, and 110c according to the degree of growth or lighting of each layer of plants.

In this case, the user closes the nutrient solution transfer hole 117 by rotating the wing control lever 127 as shown in FIG. 5 (a) in the reverse order. Then, as shown in (a) of FIG. 8, the shield control lever 227 is moved so that each shield 222 closes the nutrient solution outlet hole 211a of the bed connector 210. Then, the driving of the nutrient solution supply pump 241 is stopped.

As a result, as shown in (a) of FIG. 9, the supply of nutrient solution through the nutrient solution supply pipe 230 is stopped, the nutrient solution outflow hole 211a is blocked by the shield 222, and leakage of the nutrient solution is blocked, and each bed ( 110, 110a, 110b, and 110c) the nutrient solution shut-off valve 120 is closed to block leakage of the nutrient solution.

In this state, the user pulls the handle 137 to separate the bed modules 100, 100a, and 100b from the bed connectors 210 on both sides. Then, after rotating the locking member 139, the upper fixing band 131 is rotated upward and the beds 110, 110a, 110b, and 110c are replaced. After replacing the beds 110, 110a, 110b, and 110c, the bed modules 100, 100a, and 100b are fixed again in the previous process, and then coupled to the bed connector 210.

As described above, in the hydroponic cultivation apparatus according to the present invention, the nutrient solution supply pipe is not directly connected to each bed but connected to a bed connector, and a bed module in which a plurality of beds are combined is detachably coupled to a pair of bed connectors.

Accordingly, the user can easily perform separation and movement of the bed and exchange of the position of the bed.

In addition, the hydroponic cultivation apparatus of the present invention is provided with nutrient solution control valves at both ends of the bed, and has a nutrient solution control shield inside the bed connector to block leakage of nutrient solution even if the bed module is separated from the bed connector.
