Description

Water supplying apparatus for cultivating mushrooms

The present invention relates to a water supply device for mushroom cultivation, and more particularly, to a water supply device for mushroom cultivation capable of supplying water to the mushroom medium so that the environment of the mushroom cultivation chamber is suitable for mushroom cultivation.

In general, it is actually very difficult to perform ventilation management to properly maintain the temperature and humidity in mushroom cultivation and remove carbon dioxide gas. Mushroom cultivation of oysters or mushrooms is common in natural ventilation where vents are installed on the side windows and on the roof, and ventilation is performed depending on the degree of opening of the side windows and the ceiling exhaust. A forced ventilation method that improves the natural ventilation method is a method of installing a ventilation fan on the wall of the mushroom cultivation plant and operating the ventilation fan at a set time according to the background experience of the mushroom cultivator by a timer.

In the case of natural heating method, it is difficult to properly manage the temperature and humidity in the mushroom cultivation when growing mushrooms in windy weather, cold weather in winter, or cooling in summer. In general, the temperature and humidity of the outside air is significantly different from the environmental conditions suitable for mushroom cultivation, so even when ventilating by installing a blower, the outside is dry and cold or hot air comes in directly, so the temperature and humidity inside the mushroom cultivation change rapidly. Given this, there is a great risk of mushroom growth and disease.

So far, the environment management method of mushroom cultivation is heating by a boiler, humidity control by a humidifier, and ventilation by a ventilation fan, but has the following problems.

First, there is no automatic control of ventilation according to the carbon dioxide concentration in the grower. Second, as the cold air outside in winter and hot air outside in summer are directly ventilated with the inside air of mushroom growing, ventilation heat energy loss is very large. Third, since the outside air flows directly into the planter, the air temperature and humidity in the planter change rapidly. Fourth, since the outside air in the season of mushroom cultivation is dry, sufficient and uniform humidification is insufficient for humidity control of mushroom cultivation.

FIG. 1 is a detailed view of a nozzle of a water supply device of a ventilation apparatus for mushroom cultivation according to an embodiment of the present invention, and FIG. 2 is a partial cross-sectional view of FIG. 5.

1 to 2, the water supply device 170 according to an embodiment of the present invention serves to supply water according to a predetermined time interval to a mushroom, a pillar 171, a water injection unit ( 172), an ultrasonic sensor 173, a flow path 174, and includes a driving unit 175.

The pillar 171 is formed in a hollow cylindrical shape, and has a support portion 1711 at the bottom, extending upwardly to the mushroom badge arranged in multiple stages, and positioned at a position corresponding to the spray nozzle 1721 of each water spray portion 172. The slit hole 1712 is formed. The slit hole 1712 extends upward and downward to form a space where the spray nozzle 1721 can move up and down.

Since the pillar 171 is formed in a hollow shape, an air moving flow path F1 capable of moving air between the inner circumferential surface of the pillar 171 and the outer circumferential surface of the flow path 174 is formed in a state in which the flow path 174 is accommodated inside. The gap G is formed in the slit hole 1712 and the outer circumferential surface of the injection nozzle 1721 protruding to the outside even if the water injection portion 172 according to the driving of the lift driving unit 175 moves up and down. Therefore, by allowing air to be discharged through the gap G, air can be effectively delivered to each mushroom medium.

In addition, the support portion 1711 is provided with a driving wheel 1714 at the lower end can be moved back and forth along one direction. The driving wheel 1714 automatically moves back and forth according to the amount of water supplied to the mushroom medium through the water injection unit 172 to prevent water from being intensively supplied to one place and to be evenly supplied to the mushroom medium G as a whole. You can.

The water spray unit 172 is disposed between the pair of spray nozzles 1721 arranged in both directions and the gap G of the slit hole 1712 formed in the pillar 171 to supply water to the mushroom medium and simultaneously supply air. It serves to supply. In the present invention, the water spraying unit 172 has been described as an example in which four are stacked at predetermined intervals so as to correspond to the multi-stage of the mushroom medium, but the multi-stage is not limited thereto.

The spray nozzle 1721 is formed with a spiral shape on the outer circumferential surface to form an air passage groove 1722. In addition, the water spray part 172 may be formed of a fixed metal tube 1723 in one region in communication with the flow path 174 to be described later. The fixed metal pipe 1723 may be coupled to the lift driving unit 175, which will be described later, so that the length adjusting portion 1742 of the flow path 174 can be adjusted through the fixed metal pipe 1723. The air passage groove 1722 increases the discharge pressure of water passing through the injection nozzle 1721 when the air moves along the gap G of the slit hole 1712 through the air moving passage F1, which will be described later. It can be evenly delivered to the mushroom medium.

The ultrasonic sensor 173 is disposed adjacent to the injection nozzle 1721 to sense the location of the mushroom medium B and the location of the mushroom.

The flow path 174 is formed of a flexible material and is disposed in a vertical direction along the inside of the pillar 171 to form a connection nozzle 1741 connected to the injection nozzle 1721, respectively. The flow path 174 extending in the vertical direction to the connection nozzle 1741 includes a length adjusting unit 1742, such as a bellows, capable of contraction and expansion of length in each of the vertical directions. When the height required for each medium is determined through the ultrasonic sensor 173, the length adjusting unit 1742 moves the spray nozzle 1721 of the water spraying unit 172 through the elevating driving unit 175 to the upper or lower side. You can ensure that the water is supplied effectively at the most suitable location for the mushrooms in.

At the bottom of the flow path 174, the water supply flow path 1743 and the air supply flow path 1744 are combined. The air supply flow path 1744 is formed to be relatively larger in diameter than the water supply flow path 1743 for supplying water to the mushroom medium, and is arranged to surround the water supply flow path 1744, thereby providing a double pipe together with the water supply flow path 1744. Is formed. The air supplied through the air supply nozzle 1744 is transferred according to the opening and closing of the second valve 1356 of the additional air supply nozzle 1354, and is selectively operated through the control unit 160 to open and close the air. Can supply.

In this way, by providing water and air along the flow path, the air can be uniformly formed in the mushroom cultivation space, and uniform growth can be maintained by supplying water independently to each other.

The elevation driving unit 175 adjusts each position of the water jetting unit 172 in the vertical direction according to the growth state of the mushroom medium B and the mushrooms grown on the mushroom medium sensed through the ultrasonic sensor 173.

The lifting driving unit 175 is coupled in communication with the inside of the pillar so as to be connected to the fixed metal pipe 1723 of each water injection unit 172, and the length of the fixed metal pipe 1723 is moved up and down according to the driving of the driving cylinder on the outer circumferential surface. The discharge direction of the injection nozzle 1721 is adjusted while expanding or contracting while moving the length of the portion 1742 upward or downward. Since the fixed metal tube 1723 is formed of metal, it is connected to the lift driving unit 175, and even if it moves up and down, its diameter does not change, so it is possible to prevent the discharge amount of the discharged water from being changed.

Since the elevation driving unit 175 can change the height independently according to each mushroom medium, it is possible to provide an optimal air and water supply environment suitable for each mushroom medium.

In the present invention, the water supply device 170 has been described as an example, but may be arranged in plural by being connected in series to the mushroom cultivation chamber R.

In addition to this, the water supply device 170 may further include a mushroom medium measurement unit 180.

The temperature and humidity sensor 110 is provided in the mushroom cultivation chamber to sense temperature and humidity, and may be provided in plural to check the entire temperature state of the mushroom cultivation chamber. The temperature and humidity sensor 110 is formed on the basis of the IoT, and can provide temperature and humidity information in real time to the server S. The concentration measurement sensor 120 serves to sense the amount of carbon dioxide emitted from the mushroom when growing the mushroom. The concentration measurement sensor 120 is formed on the basis of IoT to provide carbon dioxide information of the mushroom cultivation room in real time to the server S. In the present invention, although the temperature and humidity sensor 110 and the concentration measurement sensor 120 were illustrated as being attached to the outer circumferential surface of the enclosure H, the temperature and humidity sensor 110 and the concentration measurement sensor 120 consider the indoor environment of the mushroom cultivation room. Can be placed in various locations.

The humidity control device 130 serves to maintain the temperature, humidity, and carbon dioxide amount of the mushroom cultivation chamber as predetermined criteria, and the outside air inlet pipe 131, the mixing chamber 132, the heat exchanger 133, and the blower 134 ) And a discharge unit 135. The mixing chamber 132, the evaporator 133, and the blower 133 may be disposed inside the enclosure H.

The outside air inlet pipe 131 has one end located outside the mushroom cultivation chamber R, and the other end is disposed inside the mushroom cultivation chamber to introduce outside air into the mushroom cultivation chamber R. The outside air inlet pipe 131 may further include a filter to filter foreign substances flowing in from the outside.

The mixing chamber 132 is connected to the other end of the outside air inlet pipe 131 located inside and mixes the inside air of the mushroom cultivation chamber R introduced through the inlet H1 formed in the outside air and the enclosure H First air is formed.

The heat exchanger 133 is connected to the mixing chamber 132 to exchange the temperature and humidity of the first air to predetermined conditions to form second air. The heat exchanger 133 may employ a known technique.

The blower 134 allows the outside air and the air inside the mushroom cultivation chamber R to flow into the mixing chamber 132, generates suction power so that the first air is transported along the heat exchanger 133, and the second in the other direction. It generates air discharge power.

The discharge unit 135 is to move the second air flowing out through the blower 134 to the outside and inside of the mushroom cultivation chamber R, respectively, and the discharge pipe 1351 discharged outside the mushroom cultivation chamber R It is formed by branching into a duct channel 1352 that supplies the second air to the inside of the mushroom cultivation chamber (R).

The duct flow path 1352 is provided with a variable stop 1351 driven through a driving motor at the front end. The variable aperture 1351 adjusts the amount of second air flowing into the duct channel 1352 by finely adjusting the diameter as shown in FIG. 5. The diameter of the variable aperture 1351 is variably changed according to the carbon dioxide concentration and temperature and humidity of the mushroom cultivation chamber (R) to more precisely control the amount of second air discharged to the mushroom cultivation chamber (R). If the variable aperture 1352 controls only the flow path to the mushroom cultivation chamber (R), it is not necessary to adjust the amount discharged to the outside, so that the system can be more easily implemented.

The duct flow path 1352 may further include an additional air supply flow path 1354 branching to the water supply device 170 to additionally supply air. The additional air supply flow path 1354 can increase the spray force of water by discharging it with water when water is supplied to the mushroom through the water supply device 170, so that the moisture of the mushroom can be kept constant as a whole. The additional air supply passage 1354 is supplied according to the indoor environment state of the mushroom cultivation room R, and is not always supplied when water is supplied through the water supply device 170.

In addition, the duct flow path 1352 and the additional air supply flow path 1354 may include a first valve 1355 and a second valve 1356, respectively. The first valve 1355 and the second valve 1356 allow air that has passed through the variable aperture 1351 to be supplied with air to the duct flow path 1352 or the additional air supply flow path 1354, where the air direction is ducted. It serves to selectively open and close the flow path of air so that it can be transmitted through the fan or through the water supply device 170.

For example, when air circulation is the purpose, only the first valve 1355 is opened, and the second valve 1356 is closed. Therefore, circulating air is supplied through a plurality of duct fans provided in the duct flow path 1352. When the water supply is the purpose, only the second valve 1356 is opened, and the first valve 1355 is closed. Therefore, when water is supplied through the water supply device 170, the second air is provided together to increase the water supply effect, thereby providing a more effective mushroom cultivation environment.

The LED device 140 serves to provide LED light to the mushroom medium disposed in each layer of the mushroom medium holder 141 formed in multiple stages in the mushroom growing room R.

In the LED device 140, a plurality of LED chips 142 formed of red (R), green (G), and blue chips (B) having different wavelength bands are arranged along one direction. That is, the red (R), green (G), and blue chips (B) having different wavelength bands are arranged in sequence in one direction to form the LED chip 142, and the LED chip 142 is provided in plural along one direction.

The wavelength band of each chip may be independently formed by forming blue 450 nm, red 650 nm, and green 525 nm, or a plurality of chips may be mixed to form mixed light. When forming the mixed light, it may be configured in the form of blue light + red light, blue light + green light, red light + green light, blue light + red light + green light, and the combination method of the light is not limited thereto. The LED device 140 is preferably spaced at a distance within 25 to 40 cm from the mushroom medium upward.

In this way, the plurality of LED chips may emit light by selectively emitting or mixing a plurality of chips according to the mushroom growth conditions. Therefore, by adjusting the combination of the LED chips 142 in consideration of the type and growth conditions of mushrooms, it is possible to provide optimal growth conditions according to the mushrooms.

A blocking film 143 may be disposed on the upper side of each cradle 141 to prevent light provided through the LED chip 141 from being transmitted to the lower portion. Since the cradle 141 is formed in a substantially plate-like panel, when light is provided through the LED chip 142, light can be transmitted to the lower portion through the cradle 141. When light is transmitted to the lower portion as described above, since more light amount is provided to the mushroom medium located at the lower portion, unnecessary light is additionally supplied, which may cause a problem that adversely affects growth. The blocking film 143 is preferably formed of a black film so that it can absorb rather than reflect light.

The blocking film 143 of the present invention completely shields the light from being transmitted to the lower portion, and maintains each space as a completely independent space, so that the light transmitted from the LED chip 142 is in each independent cradle 141 space. It is possible to maintain optimal mushroom growth conditions by intensively shining.

The IoT camera 150 serves to photograph the mushroom cultivation chamber R in real time, and may be provided in plural to photograph the entire mushroom cultivation chamber R. The IoT camera 150 is interlocked with the user terminal M, and can zoom in and shoot a location desired by the user through the user terminal M, and the captured image information is stored in the server S in real time.

The pre-stored growth information is video information implemented in the existing growth state and big data, and if there is a location where an abnormality occurs in the growth state, the corresponding location is enlarged and photographed through the IoT camera 150 to the user terminal M It is possible to take immediate action by sending it as an alarm to indicate whether the growth condition is abnormal.

The control unit 160 controls to move the mushroom cultivation chamber R and the amount of the second air discharged to the outside based on the temperature and humidity sensed through the temperature and humidity sensor 110 and the concentration measurement sensor 120. The control unit 156 adjusts the size of the aperture 1351 provided in the discharge unit 135. Therefore, since the amount of the second air flowing into or out of the mushroom cultivation chamber is determined, the indoor temperature and humidity and the carbon dioxide amount of the mushroom cultivation chamber can be maintained at predetermined values.

In addition, the control unit 160 allows the first valve 1355 or the second valve 1356 to be opened and closed according to the operating state of the water supply device 170, thereby discharging air through the duct fan inside the mushroom cultivation chamber R. It is possible, or it is possible to allow air to be discharged together with water through a water supply device.

In addition to this, the control unit 160 additionally controls the number of water jets discharged from the spray nozzle 172, the water discharge amount, and the discharge time based on the wet state of the mushroom medium sensed through the mushroom medium measuring unit 180 described above. By maintaining the optimal condition as well as the indoor environment of the mushroom cultivation room, the optimal mushroom cultivation environment can be induced more comfortably.
