[0041] The bottom of the hydroponic box 3 is provided with a plurality of sealed plug holes 31 which are sealed and plugged with the plug connector 62. The hydroponic box 3 is provided with a plurality of mixed water spraying components 32 which are connected with the sealed plug holes 31. The side of the hydroponic box 3 is provided with positioning holes 33 for the plugging of the limiting components 64. The limiting components 64 are gradually inserted into or out of the positioning holes 33 as the pressure of the chamber 63 increases or decreases. When the limiting components 64 are fully inserted into the positioning holes 33, the sealed plug holes 31 are sealed against the plug connector 62.

[0042] When in use, the eggplants are planted in the hydroponic basket 4, and the eggplants are placed on the placement plate 6 through the hydroponic box 3. At this time, the plug connector 62 is inserted into the sealed plug hole 31, and then the corresponding liquid parameters are set according to the needs. Then the water mixing component mixes the corresponding salt, culture solution, water and other liquids according to the liquid parameters. After the mixing is completed, the liquid enters the chamber 63. At this time, the limiting component 64 is gradually inserted into the positioning hole 33. In the process of the limiting component 64 being inserted into the positioning hole 33, the hydroponic box 3 gradually moves down, and the sealed plug hole 31 and the plug connector 62 are gradually sealed and fitted. Then, when the limiting component 64 is completely inserted into the positioning hole 33, the liquid in the chamber 63 passes through the water inlet channel 3225 and the plug connector 62 into the mixing water spraying component 32. The mixing water spraying component 32 sprays the corresponding liquid and stirs and mixes it, so that the salt in the liquid is evenly distributed to ensure use;

[0043] The cross section of the positioning hole 33 is triangular, and the hypotenuse is located at the bottom. A cylindrical hole for the position limiting component 64 to be inserted and positioned is provided at the deepest part of the positioning hole 33 .

[0044] Preferably, the pressure required for the limiting assembly 64 to be fully inserted into the positioning hole 33 is less than the minimum pressure for starting the mixing water spray assembly 32 to avoid leakage.

[0045] In this embodiment, the mixing water spraying assembly 32 includes a fixed cylinder 321 connected to the hydroponic box 3 by threads, at least one rotating driving member 322 disposed on the fixed cylinder 321, a centrifugal connecting member 323 disposed above the rotating driving member 322, and a rotating barrel 324 located above the centrifugal connecting member 323, and the fixed cylinder 321 is independently connected to the sealing plug hole 31;

[0046] The rotating driving member 322 is connected to the fixed cylinder 321 and the centrifugal connecting member 323 respectively, and the rotating driving member 322 can gradually drive the rotating barrel 324 and the centrifugal connecting member 323 to rotate as the water pressure of the fixed cylinder 321 increases;

[0047] The centrifugal connecting piece 323 is connected to the rotating barrel 324. The centrifugal connecting piece 323 gradually opens when rotating, so that the rotating barrel 324 is connected to the fixed barrel 321. A plurality of stirring plates 326 are arranged along the outer circumferential side of the rotating barrel 324. The stirring plates 326 are provided with drainage holes connected to the rotating barrel 324.

[0048] The rotating barrel 324 located at the top is not connected to the fixed barrel 321;

[0049] When in use, the liquid enters the rotating drive member 322 from the fixed cylinder 321, and the rotating drive member 322 rotates and drives the rotating barrel 324 and the centrifugal connecting member 323 to rotate. As the pressure increases, the speed of the centrifugal connecting member 323 increases and opens. At this time, the liquid in the fixed cylinder 321 enters the rotating barrel 324 through the rotating drive member 322 and the centrifugal connecting member 323 and is discharged. The rotating barrel 324 drives the stirring plate 326 to stir the liquid.

[0050] In this embodiment, the rotary drive member 322 includes an intermediate cylinder 3224 rotatably connected to the inner wall of the fixed cylinder 321, a fan wheel 3223 coaxially fixed to the intermediate cylinder 3224, a fan blade 3221 fixed to the fan wheel 3223, and a water inlet channel 3225 opened on the fixed cylinder 321. The intermediate cylinder 3224 is fixedly connected to the centrifugal connecting member 323.

[0051] The fixing cylinder 321 is provided with an annular groove, and the fan wheel 3223 is rotatably sealed and connected in the annular groove. A driving ring groove is also provided on one side of the outer circumference of the annular groove. The fan blade 3221 is located in the driving ring groove and can rotate along the driving ring groove with the center of the fan wheel 3223 as the center.

[0052] The fixed cylinder 321 is also provided with a drainage channel 3222. The water inlet channel 3225 and the drainage channel 3222 are both connected to the driving ring groove to drive the fan blade 3221 to rotate. The drainage channel 3222 is connected to the outer circumferential side of the fixed cylinder 321, and the water inlet channel 3225 is connected to the fixed cylinder 321.

[0053] When in use, the liquid in the fixed cylinder 321 passes through the water inlet channel 3225 to push the fan blade 3221 to move, the fan wheel 3223 rotates and drives the middle cylinder 3224 to rotate, and then the liquid is discharged into the hydroponic box 3 through the drainage channel 3222;

[0054] Among them, the structure for rotating through water, fan blades 3221 and fan wheel 3223 is an existing technology and can be adjusted according to actual content to ensure rotation drive.

[0055] In this embodiment, the centrifugal communication member 323 includes a centrifugal disc 3234 rotatably connected to the fixed cylinder 321, two contact sealing blocks 3233 that are in contact and sealed with each other, and two centrifugal blocks 3231. The centrifugal disc 3234 is fixed coaxially with the intermediate cylinder 3224. The axis of the centrifugal disc 3234 is provided with a sealed sliding cavity 3232 that is respectively connected with the intermediate cylinder 3224 and the rotating barrel 324. The contact sealing block 3233 is in sliding contact and sealed with the sealed sliding cavity 3232.

[0056] Slide grooves are mirrored on both sides of the centrifugal disc 3234, and the centrifugal block 3231 is elastically slidably connected in the slide grooves. The centrifugal block 3231 is connected to the contact sealing block 3233;

[0057] When in use, as the intermediate cylinder 3224 rotates, the centrifugal disc 3234 gradually rotates. During the rotation, the centrifugal block 3231 drives the two contact sealing blocks 3233 to move away from each other, so that the intermediate cylinder 3224 is connected to the rotating barrel 324. When the rotation speed decreases, the centrifugal force decreases, the centrifugal block 3231 elastically resets and pushes the two contact sealing blocks 3233 to contact and seal.

[0058] The elastic connection can be realized by using elastic components such as springs.

[0059] In this embodiment, the limiting assembly 64 includes a cylinder 643 fixed in the chamber 63, two limiting rings 641 fixed in the cylinder 643, a sealing plug 647 sealed and inserted in the cylinder 643 and located between the two limiting rings 641, a plug-in column 642 that can be inserted into the positioning hole 33, and a liquid inlet and outlet assembly. The sealing plug 647 is fixed to the plug-in column 642. The liquid inlet and outlet assembly drives the plug-in column 642 to extend and retract as the pressure of the chamber 63 changes. The cylinder 643 is connected to an air bag 646 fixed on the placement plate 6, and the incubator 7 corresponding to the air bag 646 is made of transparent material.

[0060] When the pressure in the chamber 63 increases, the liquid inlet and outlet assembly controls the liquid to enter the cylinder 643, and pushes the sealing plug 647 and the plug-in column 642 to extend, so that the plug-in column 642 is inserted into the positioning hole 33. When the pressure is restored, the plug-in column 642 is still located in the positioning hole 33 to ensure the positioning effect. When it needs to be removed, the liquid needs to be extracted through the water mixing assembly to form a negative pressure in the chamber 63. At this time, the sealing plug 647 and the plug-in column 642 are separated from the positioning hole 33 under the action of the liquid inlet and outlet assembly. Through the above process, the liquid remaining in the chamber 63 can be discharged to ensure the accuracy of the subsequent salt adjustment.

[0061] When the salinity is adjusted, part of the liquid in the hydroponic box 3 enters the mixing and spraying assembly to reduce the salinity of the overall water level, making it easier to adjust the salinity later.

[0062] In this embodiment, the liquid inlet and outlet assembly includes a guide cylinder 644 fixed in the chamber 63, a guide rod 645 sealed and plugged in the guide cylinder 644, an air pump 648 sealed and plugged in the cylinder body 643 through a sealing member, a negative pressure cylinder 640 fixed in the chamber 63, and a sealing rod 649 sealed and plugged in the air pump 648.

The air pump 648 is elastically connected to the cylinder body 643 and connected to the guide rod 645.

[0063] The sealing rod 649 is elastically connected to the negative pressure cylinder 640 through a spring. The sealing rod 649 is sealingly slidably connected to the negative pressure cylinder 640 through a piston and cannot be separated from the negative pressure cylinder 640. The sealing rod 649 is provided with a connecting hole axially downward, and the connecting hole is not connected to the end of the sealing rod 649 located in the negative pressure cylinder 640. The sealing rod 649 is provided with an air extraction hole 6491 located in the air extraction cylinder 648 on the circumferential side. The air extraction hole 6491 is offset from the circular hole in the upper and lower positions.

[0064] When in use, as the pressure of the chamber 63 increases, the guide rod 645 moves along the guide cylinder 644 and pushes the vacuum cylinder 648 to move, so that the vacuum cylinder 648 is no longer in sealing contact with the cylinder body 643. At this time, liquid enters the cylinder body 643, and the sealing plug 647 moves. When the pressure of the chamber 63 is restored, the vacuum cylinder 648 is elastically reset, and the sealing plug 647 remains stationary, ensuring the positioning effect.

[0065] When the chamber 63 is under negative pressure, the guide rod 645 remains different and the sealing rod 649 moves so that the air suction hole 6491 is separated from the air suction cylinder 648, and the liquid in the cylinder body 643 is discharged through the circular hole and the air suction hole 6491, and the sealing plug 647 is reset.

[0066] In this embodiment, the plug connector 62 includes a plug-in sleeve 621 detachably connected to the placement plate 6 through threads and a sealing contact ring 622 fixed to the plug-in sleeve 621, and the sealing contact ring 622 contacts and seals the sealing plug-in hole 31;

[0067] When in use, the sealing contact ring 622 ensures the plug-in seal between the plug-in hole and the plug-in tube 621 to avoid liquid leakage.

[0069] When in use, water, nutrient solution and other liquids are placed in the box A75 and the box B76 as needed. When a mixed liquid needs to be output, the corresponding liquid is extracted into the mixing device according to the proportion requirements and the brine concentration of the brine cabinet 1 for mixing, and the corresponding liquid is input into the chamber 63 under the action of the culture peristaltic pump 79 and the delivery pipeline 70;

[0070] Among them, the corresponding detection instrument can be added according to the actual needs for the salt water concentration;

[0071] Preferably, the mixing device can also be connected to an external water tank through a pipeline and a valve, so that excess liquid can be discharged.
