본 고안은 침수식 콩나물 재배상자 배수구의 개폐장치에 관한 것이다. 일반적으로 콩나물 재배에는 살수식 재배법과 침수식 재배법이 있으며 침수식 콩나물 재배법에서는 일정시간마다 살수하여 콩나물이 침수되게 재배상자에 물이 채워진 다음 물이 빠지도록 하여 재배하는 것이므로 콩나물 재배상자에 침수된 물이 배수되게 하는 여러 가지 배수수단이 알려져 있다.The present invention relates to an opening and closing device of the submerged sprout sprout box drain. In general, the sprout sprout cultivation method and the submerged cultivation method, and the submerged bean sprout cultivation method is to cultivate so that the sprouts are flooded every time to fill the growing box so that the sprouts are submerged, and then the water is drained, so that the water immersed in the bean sprout growing box Various means for drainage are known.

본 고안과 관련한 침수식 재배상자의 산행기술의 예로서 공개실용신안공보 실1999-0041866호(1999. 12. 27공개)는 수조에 콩나물시루를 놓고 일정한 시간마다 펌프에 의해 수조에 물을 채워서 콩나물시루가 침수되게 한 다음 다시 펌프에 의해 수조의 물을 배수시켜 침수와 배수를 반복하게 된 것이다. 이는 침수와 배수에 펌프의 동력을 사용하기 때문에 콩나물의 재배 코스트가 높고 작업이 번거로운 문제점이 있다.As an example of the climbing technology of the submerged cultivation box related to the present invention, Published Utility Model Publication No. 1999-0041866 (published on Dec. 27, 1999) places bean sprouts in a tank and fills the tank with water by a pump at regular intervals. After flooding the shiru, the water in the tank was drained again by the pump to repeat the immersion and drainage. This is because the use of the power of the pump for immersion and drainage has a problem that the cost of growing bean sprouts is high and cumbersome work.

또 다른 예로 등록특허공보 제10-0302906호(2001. 07. 06공고)는 재배실에 여러 개의 콩나물 재배상자를 재치하고 각 재배상자마다 급수관과 배수관을 관접하여 급수에 의해 재배상자에 물을 채워서 콩나물을 침수시키고 다시 침수된 물을 배수관으로 하여 침수와 배수를 반복하게 된 것으로 배관구조가 복잡하고 많은 노력(勞力)과 급,배수의 펌프동력의 비용이 소요되는 문제점이 있다.In another example, Korean Patent Publication No. 10-0302906 (August 06, 2001) places several bean sprout cultivation boxes in a cultivation room, fills the cultivation boxes with water by supplying water and drain pipes to each cultivation box. The immersion of bean sprouts and the immersion and drainage are repeated by using the submerged water as a drainage pipe, which is complicated in piping structure and requires a lot of effort and cost of pumping power.

또 다른 예는 등록실용신안공보 20-0350008호(2004. 05. 08공고), 등은 콩나물 재배상자의 배수홈에 사이폰 배수관을 설치하여 재배상자에 물이 소정수위로 채워지면 사이폰 배수관을 통하여 자동으로 물이 배수되는 것으로 외부동력을 사용하지 않고 배수되고 배수에 별도의 노력이 들지 않는 이점이 있다. 반면, 콩껍질 등 이물질에 의하여 사이폰 배수관이 빈번하게 막히어 사이폰 작용이 제대로 이루어지 않아 장시간 침수로 콩나물이 약화되거나 부패될 우려가 있는 비비점이 있다.Another example is Registered Utility Model Publication No. 20-0350008 (announced on May 08, 2004), etc., the siphon drain pipe is installed in the drain groove of the bean sprouts growing box so that the water is filled to the predetermined level. The water is automatically drained through it, it is drained without using external power, and there is an advantage that no extra effort is required for drainage. On the other hand, the siphon drain pipe is frequently clogged by foreign substances such as soybean shells, so that the siphon action is not properly performed, and there is a boiling point that the bean sprouts may be weakened or rot due to prolonged immersion.

본 고안은 종래의 이러한 문제점을 시정하기 위하여, 침수식 콩나물 재배상자에 장착되는 레버의 일단부에는 배수구의 개폐밸브를 연결하고 레버의 타단부에는 낙수공이 형성된 중량컵을 형성하여 콩나물 재배실에 재치한 콩나물 재배상자에 침수되게 물이 공급되면 중량컵에 물이 채워져서 중량컵의 무게로 레버의 타단부가 하강 작동되면서 레버의 일단부가 개폐밸브를 개방시켜 재배상자의 물이 배수구로 배수되고 그 후 중량컵의 물이 서서히 낙수되어 중량컵이 비워지기 까지 배수구가 개방 유지되며 중량컵의 물이 모두 배수되어 비게 되면 개방되었던 중량컵이 가벼워져서 개폐밸브의 자중으로 배수구가 닫히도록 구성한 것이다.The present invention, in order to correct these problems in the prior art, one end of the lever is mounted on the submersible bean sprout cultivation box is connected to the opening and closing valve of the drain and the other end of the lever to form a weight cup formed with a drop hole is placed in the bean sprout cultivation room When water is supplied to a bean sprouts cultivation box, the weight cup is filled with water, and the other end of the lever is lowered by the weight of the weight cup, and one end of the lever opens the opening / closing valve so that the water in the cultivation box is drained to the drain. After the water in the weight cup is slowly falling down, the drain is kept open until the weight cup is empty, and when all the water in the weight cup is drained, the open weight cup becomes light and the drain is closed by the weight of the on / off valve.

본 고안은 재배실의 상부측에서 살수하여 각 재배상자에 물이 채워져 콩나물이 침수되게 할 때 중량컵에도 물이 담겨지므로 중량컵이 개폐밸브에 비하여 무겁게 되고 따라서 중량컵이 하강되면서 레버의 일단부에 연결된 배수구의 개폐밸브를 개방시킨다. 이러한 배수구의 개방상태에서 소정시간 물이 공급됨으로 배수량에 비하여 급수량이 많기 때문에 급수중에는 침수상태를 유지한다. 급수작동이 정지되면 재배상자의 물은 개방된 배수구를 통하여 모두 신속하게 빠진다.The present invention is sprayed from the upper side of the cultivation room so that water is contained in the weight cup when water is soaked in each cultivation box so that the bean sprouts are flooded. Open the valve on the drain connected to the outlet. Since water is supplied for a predetermined time in the open state of such a drain, the water supply amount is larger than the drainage amount, so that the water is inundated. When the water supply is stopped, the water in the grower is quickly drained through the open drain.

재배상자의 물이 배수된 후에도 중량컵의 물은 조금씩 낙수공으로 낙수되기 때문에 상당시간 중량을 가지게 되어 배수구의 개폐밸브를 개방유지 시킨다. 이때 개방된 배수구를 통하여 공기가 재배상자에 유입되어 침수상태에서 노출된 콩나물에 공기를 접촉시켜 콩나물의 성장을 촉진한다.Even after the water in the cultivation box is drained, the water in the weight cup falls into the dripping hole little by little, so it has a weight for a long time, thereby maintaining the open / close valve of the drain. At this time, the air flows into the cultivation box through the open drainage hole, so that the sprouts are contacted with air so as to promote the growth of the bean sprouts.

중량컵의 물이 모두 빠지면 중량이 가벼워지므로 보다 무거운 개폐밸브의 자중으로 배수구가 닫히고 다음의 침수준비를 하며 간헐적인 급수동작에 따라 자동으 로 콩나물 재배상자의 침수와 배수가 반복된다.When all the water in the weight cup is drained, the weight becomes lighter. Therefore, the drainage port is closed by the weight of the heavy opening / closing valve, and the next saliva level ratio is used.

본 고안의 장치는 구조가 간단하여 취급이 용이하고 동작이 확실하여 배수구가 막히거나 배수불량에 의한 콩나물이 약화되거나 부패될 염려가 전혀 없고 급, 배수에 전혀 동력이 사용되지 않으므로 콩나물 재배코스트가 보다 저렴하게 되며, 물의 중량을 이용하여 보다 효과적으로 침수식 콩나물 재배상자의 배수구를 자동 개폐할 수 있게 안출한 것이다.The device of the present invention is simple in structure, easy to handle and reliable in operation, so there is no fear of weakening or decaying bean sprouts due to drainage drainage or poor drainage, and no power is used for feeding and draining. Inexpensive, and by using the weight of the water is more effective to automatically open and close the drain hole of the submersible bean sprouts growing box.

도1 내지 도3에 표시된 바와 같이, 콩나물 재배상자(B)에 부착된 지지판(1a)에 레버(1)의 한 지점을 지지축(1x)으로 지지되게 설치하고 레버(1)의 일단부에는 재배상자(B)의 배수홈(D)에 형성된 배수구(2)를 개폐하는, 평형 추(3a)를 가진 개폐밸브(3)를 로드(1b)로 연결되게 형성하고 레버(1)의 타단부에는 물의중량에 의하여 상기 개폐밸브(3)를 개폐하는 작은 낙수공(4h)이 형성된 중량컵(4)을 형성하여, 중량컵(4)에 물이 채워지면 중량컵(4)이 레버(1)의 지지축(1x)을 지점으로 레버(1)의 타단부가 하강 작동되면서 레버(1)의 일단부가 개폐밸브(3)를 개방시켜 중량컵(4)의 물이 낙수공(4h)으로 모두 배수되기 까지 개폐밸브(3)를 개방 유지할 수 있게 구성된 것이다.As shown in Figs. 1 to 3, a point of the lever 1 is installed on the support plate 1a attached to the bean sprouts growing box B so as to be supported by the support shaft 1x, and at one end of the lever 1 The opening and closing valve 3 having the counterweight 3a, which opens and closes the drain 2 formed in the drainage groove D of the growing box B, is formed to be connected to the rod 1b and the other end of the lever 1 There is formed a weight cup (4) formed with a small drop hole (4h) for opening and closing the on-off valve (3) by the weight of the water, the weight cup (4) is the lever (1) The other end of the lever (1) is lowered with the support shaft (1x) of) as the one end of the lever (1) opens the on-off valve (3), so that the water in the weight cup (4) to the falling hole (4h) It is configured to keep the on-off valve 3 open until all are drained.

도3은 본 고안의 동일한 구성에서 콩나물 재배상자(B) 배수구(2)의 아래쪽에서 레버(1)의 일단부에 형성된 로드(1b)로 개폐밸브(3)를 개방하게 된 실시예시도 이다.Figure 3 is an embodiment showing the opening and closing valve (3) to the rod (1b) formed at one end of the lever (1) in the lower part of the bean sprout cultivation box (B) drain port 2 in the same configuration of the present invention.

이와 같이 구성된 본 고안은 도4 및 도6도에 표시된 바와 같이, 중량컵(4)이 비어 있는 동안은 개폐밸브(3)가 평형 추(3a)로 인하여 보다 무거워서 자중(自重)으로 하강되어 배수구(2)가 닫힌다. 도5 및 도7에 표시된 바와 같이, 소정시간 후, 도시되지 않은 재배실의 상부측에서 급수수단에 의해 살수하면 배수구(2)가 닫혀 있어 각 재배상자에 물이 채워져 콩나물이 침수된다. 살수된 물은 중량컵(4)에도 담겨지므로 중량컵(4)이 상대적으로 개폐밸브(3)에 비하여 무겁게 되고 따라서 중량컵(4)이 하강되면서 지지축(1x)을 지점으로 레버(1)의 일단부가 상승되면서 레버(1)에 로드(1b)로 연결된 개폐밸브(3)를 작동하여 재배상자(B)의 배수홈(D)에 형성된 배수구(2)를 개방시킨다. 이러한 배수구(2)의 개방상태에서도 소정시간 물이 공급되고 이 때 배수구(2)로 배수되는 수량 보다 공급되는 수량이 많으므로 잠정적으로 침수상태를 유지한다. 급수작동이 정지되면 재배상자(B)의 물은 개방된 배수구(2)를 통하여 모두 빠진다.4 and 6, the present invention configured as described above, while the weight cup (4) is empty, the on-off valve (3) is heavier due to the counterweight (3a) is lowered to its own weight (self-weight) drain (2) is closed. As shown in Fig. 5 and Fig. 7, after a predetermined time, when the water is sprayed by the water supply means in the upper side of the cultivation chamber (not shown), the drainage port 2 is closed, so that each cultivation box is filled with water and the bean sprouts are flooded. The sprinkled water is also contained in the weight cup (4), so that the weight cup (4) becomes relatively heavy as compared to the on-off valve (3), so that the weight cup (4) is lowered, and the support shaft (1x) to the point (1) While the one end of the rise is operated by the opening and closing valve (3) connected to the lever (1) by the rod (1b) to open the drain (2) formed in the drain groove (D) of the cultivation box (B). Even in the open state of the drain 2, water is supplied for a predetermined time, and at this time, the amount of water to be supplied is larger than that to be drained to the drain 2 so that the water is temporarily flooded. When the water supply operation is stopped, the water in the cultivation box (B) is all drained through the open drain (2).

한편, 재배상자의 물이 배수된 후에도 중량컵(4)의 물은 낙수공(4h)으로 조금씩 낙수되기 때문에 상당 시간 중량을 가지게 되어 배수구(2)의 개폐밸브(3)를 개방 유지시키다. 이때 개방된 배수구(2)를 통하여 공기가 재배상자(B)에 유입되어 침수상태에서 노출된 콩나물에 공기를 접촉시켜 콩나물의 성장을 촉진한다.On the other hand, since the water in the weight cup 4 is gradually dropped into the falling hole 4h even after the water of the cultivation box is drained, the water has a weight for a considerable time, thereby maintaining the open / close valve 3 of the drain 2. At this time, the air flows into the cultivation box (B) through the open drain (2) to contact the air sprouts exposed in the submerged state to promote the growth of the bean sprouts.

중량컵(4)의 물이 모두 빠지면 중량이 가벼워지므로 보다 무거운 개폐밸브(3)의 자중으로 배수구(2)가 닫히고 다음의 침수준비를 하며, 간헐적인 급수조작에 따라 자동으로 콩나물 재배상자의 침수와 배수가 반복된다.When all the water in the weight cup (4) is drained, the weight becomes lighter, so the drain opening (2) is closed by the weight of the heavier opening / closing valve (3) and the next saliva level ratio is made. And multiples are repeated.

본 고안은 물의 중력을 이용하여 레버를 작동시켜서 배수구의 개폐밸브를 자동으로 개폐하 수 있게 구성하였기 때문에 구조가 간단하여 취급이 용이하고 개폐밸브의 개폐동작이 확실하며 콩껍질 등의 이물질로 배수구가 막힐 우려가 없고 배수불량에 의하여 콩나물이 성장이 징해되거나 부패될 염려가 전혀 없다.This design is designed to open and close the drain valve automatically by operating the lever using the gravity of the water, so the structure is simple and easy to handle, the opening and closing operation of the valve is sure, the foreign matter such as bean shell There is no fear of clogging, and there is no fear of bean sprouts to grow or rot due to poor drainage.

또 급, 배수에 전혀 동력이 사용되지 않으므로 콩나물 재배코스트가 보다 저렴하게 되며, 중량컵에 담기는 물의 중량을 이용하여 침수식 콩나물 재배상자의 배수구를 유효하게 자동 개폐할 수 있는 효과가 있다.In addition, since no power is used for feeding and draining, the bean sprout cultivation cost becomes cheaper, and there is an effect of effectively automatically opening and closing the drain hole of the submerged bean sprouts growing box using the weight of the water contained in the weight cup.
