In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.

[0034] The embodiment of the present invention provides a soilless cultivation device for planting vegetables in an agricultural garden, comprising a frame 1 with universal wheels at the four corners of the bottom, a plurality of culture mechanisms 2 are fixedly connected at intervals inside the frame 1, a nutrient delivery component 6 is arranged on the top of the frame 1, and the nutrient delivery component 6 delivers nutrient solution to the culture mechanisms 2 at each layer, the culture mechanisms 2 include a culture box 4, a culture tray 3 is arranged inside the culture box 4, a regulating component 5 is installed at the front end of the culture box 4, and the regulating component 5 controls the nutrient delivery component 6 to communicate with the culture tray 3 or the culture box 4,

[0035] The incubator 4 comprises a box body 41, a support tray 42 is mounted on the inner wall of the box body 41, a plurality of groups of mounting grooves 43 are arranged at intervals on the upper end surface of the support tray 42, an outer metal support net 45 is fixedly connected in the mounting groove 43, and a semi-permeable membrane 44 is mounted in the outer metal support net 45.

[0036] The culture tray 3 includes a storage tray 33 , an inner channel 31 is provided inside the storage tray 33 , a plurality of storage grooves 34 are spaced apart on the upper end surface of the storage tray 33 , an inner metal support mesh 32 is fixedly connected to the bottom of the storage groove 34 , and the inner channel 31 is connected to the plurality of inner metal support meshes 32 .

[0037] See also Figure 1 - Figure 7 The general nutrient solution and the special component nutrient solution are both placed in the nutrient delivery component 6 and delivered to the placement of each layer of the culture mechanism 2, wherein the general nutrient solution is delivered to the inner cavity of the box body 41 through the second feed port 53, and passes through the outer metal support mesh 45 to enter the semipermeable membrane 44. Since the inner metal support mesh 32 corresponds to the position of the mounting groove 43, and the inner metal support mesh 32 is installed inside the semipermeable membrane 44, the general nutrient solution in the semipermeable membrane 44 enters the inner metal support mesh 32 to provide nutrients for the crops in the inner metal support mesh 32. When the crop needs a special component nutrient solution during its growth stage, the special component nutrient solution is delivered to the inner channel 31 through the first feed port 52, and the nutrient solution flows into the inner metal support mesh 32 and mixes with the general nutrient solution to provide a nutrient formula of suitable components for the crop. At the same time, the presence of the semipermeable membrane 44 prevents the special nutrient solution from interfering with the general nutrient solution in the box body 41.

[0038] It should be noted that the inner channel 31 is provided with an inlet connected to the regulating component 5 , and the inner channel 31 includes various channels connected to the inner metal support mesh 32 .

[0039] It should be supplemented that the inner metal support mesh 32, the semipermeable membrane 44 and the outer metal support mesh 45 have the same shape and are of matching size. The semipermeable membrane 44 is arranged at adjacent positions between the inner metal support mesh 32 and the outer metal support mesh 45. When the inner metal support mesh 32 is installed in the semipermeable membrane 44, the inner wall of the semipermeable membrane 44 contacts the outer wall of the inner metal support mesh 32, and at the same time, the outer wall of the semipermeable membrane 44 contacts the inner wall of the outer metal support mesh 45.

[0040] In this embodiment, the frame 1 includes a support frame 11 , in which a plurality of groups of mounting plates 12 are symmetrically spaced and fixedly connected, and the culture mechanism 2 is mounted on the upper end surfaces of two groups of mounting plates 12 corresponding horizontally.

[0041] See also Figure 2 The culture mechanism 2 is placed on the upper end surface of the mounting plate 12 , and the culture mechanism 2 can be pulled out from the inside of the support frame 11 by pulling the culture mechanism 2 outward.

[0042] It should be supplemented that the outer wall of the culture mechanism 2 is provided with a handle for convenient pushing and pulling.

[0043] In this embodiment, the nutrient delivery component 6 includes a storage box 61, which is installed on the top of the support frame 11. The side wall of the storage box 61 is fixedly connected to a main feeding pipe 62. The side wall of the main feeding pipe 62 is fixedly connected to several groups of special nutrient delivery pipes 63 and several groups of universal nutrient delivery pipes 64 at intervals. The ends of the several groups of special nutrient delivery pipes 63 and the several groups of universal nutrient delivery pipes 64 facing away from the main feeding pipe 62 are fixedly connected to the regulating component 5.

[0044] See also Figure 2 A feed port is provided at the top of the storage box 61, and a general storage box and multiple special ingredient storage boxes are respectively provided in the storage box 61. Nutrient solution can be added into the storage box 61 through the feed port, and the nutrient solution passes through the main feeding pipe 62 by gravity and is then transported to the inner channel 31 through the special nutrient delivery pipe 63, and is transported to the box body 41 through the general nutrient delivery pipe 64.

[0045] It should be noted that a universal feeding pipe and a special ingredient feeding pipe are provided in the main feeding pipe 62, wherein the universal feeding pipe is connected to the universal nutrient delivery pipe 64, and the special ingredient feeding pipe is connected to the special nutrient delivery pipe 63, and valves and connecting screw sleeves 65 are provided on the special nutrient delivery pipe 63 and the universal nutrient delivery pipe 64, and the special nutrient delivery pipe 63 and the universal nutrient delivery pipe 64 are connected to the inner channel 31 and the box body 41 respectively through the connecting screw sleeve 65.

[0046] It should also be added that a page display window is provided on the storage box 61, so that the storage amount of the nutrient solution can be observed at any time and replenished in time.

[0047] In this embodiment, an accommodation groove 51, a first feed port 52 and a second feed port 53 are spaced apart on the inner wall of the box body 41. The accommodation groove 51 is arranged perpendicular to the first feed port 52 and the second feed port 53, and the accommodation groove 51 connects the first feed port 52 and the second feed port 53. A blocking member 55 is slidably connected in the accommodation groove 51, and the blocking member 55 selectively controls the opening and closing of the first feed port 52 and the second feed port 53.

[0048] See also Figure 4 The first feed port 52 and the second feed port 53 are arranged in parallel, and are respectively connected to the inner channel 31 and the inner cavity of the support tray 42. The placement groove 51 passes through the side walls of the second feed port 53 and the first feed port 52 in sequence, and the lower end surface of the placement groove 51 is lower than the bottom of the second feed port 53, and the upper end surface of the placement groove 51 is higher than the top of the first feed port 52. The blocking member 55 is slidably connected in the placement groove 51, and when the second feed port 53 is opened, the first feed port 52 remains closed, and when the second feed port 53 is closed, the first feed port 52 is opened.

[0049] It should be noted that since the nutrient solution components required for soilless cultivation of most crops are similar, generally, a universal nutrient solution can meet the growth needs. However, during special periods of crops, such as sprouting and flowering, it is necessary to provide nutrients with special components for this growth stage. At this time, the normally closed first feed port 52 is opened to deliver nutrient solution with special components into the culture tray 3 to meet the needs of the crops, thereby reducing the frequent changes of nutrient solution formulas that cause a large amount of manpower and material resources to be consumed.

[0050] In this embodiment, the blocking member 55 includes a first baffle plate 551 and a screw rod 552, one end of the screw rod 552 is rotatably connected to the second baffle plate 554, the other end of the screw rod 552 passes through the first baffle plate 551 and extends out of the top of the box body 41, the outer wall of the screw rod 552 is threadedly connected to a screw sleeve 553, the screw sleeve 553 is located at an adjacent position between the first baffle plate 551 and the second baffle plate 554, the outer wall of the screw sleeve 553 is fixedly connected to a limiting slide rod 555, and the end of the limiting slide rod 555 facing away from the screw sleeve 553 is fixedly connected to a floating plate 556.

[0051] See also Figure 5 When the water level in the box body 41 rises, the float plate 556 receives the buoyancy and drives the second baffle plate 554 and the first baffle plate 551 to move upward through the screw sleeve 553. When the second baffle plate 554 moves to the second feed port 53, the universal nutrient solution stops feeding. At the same time, the first baffle plate 551 moves out of the first feed port 52, and the special ingredient nutrient solution enters the inner channel 31 from the first feed port 52. The two nutrient solutions in the inner metal support net 32 ​​are mixed to provide special nutrients for crops. When the liquid level in the box body 41 decreases, the float plate 556 descends, the second feed port 53 is opened, and the universal nutrient solution is transported into the box body 41. At the same time, the special nutrient solution transport amount in the first feed port 52 is reduced to avoid excessive concentration of the special nutrient solution and the burning of the seedlings. By rotating the screw rod 552, the screw sleeve 553 is moved, thereby adjusting the height of the float plate 556, thereby controlling the page height of the universal nutrient solution in the box body 41, and adjusting the concentration of the two mixed nutrient solutions after mixing.

[0052] It should be noted that the first baffle 551 and the second baffle 554 are rotatably connected to the screw 552, and a limit ring 557 is provided at the connection between the first baffle 551 and the floating plate 556 and the screw 552. The limit ring 557 is fixedly connected to the surface of the screw 552 to keep the distance between the first baffle 551 and the second baffle 554 unchanged.

[0053] It should also be added that the height of the second baffle 554 and the first baffle 551 is greater than the hole height of the first feed port 52 and the second feed port 53, the distance a between the first baffle 551 and the second baffle 554 is not greater than the distance b between the first feed port 52 and the second feed port 53, and when the floating plate 556 moves, one group of the first feed port 52 and the second feed port 53 always remains closed.

[0054] In this embodiment, a slide groove 54 is provided on one side of the second feed port 53 close to the support tray 42 . The slide groove 54 is vertically arranged, and a limiting slide rod 555 is slidably connected in the slide groove 54 .

[0055] See also Figure 4 and Figure 5 One end of the limiting slide rod 555 is fixedly connected to the outer wall of the screw sleeve 553, and the other end extends through the slide groove 54 and is fixedly connected to the floating plate 556. The limiting slide rod 555 slides in the slide groove 54 and limits the screw sleeve 553 to prevent the screw sleeve 553 from deflecting with the screw 552 when the screw 552 rotates.

[0056] In this embodiment, the semipermeable membrane 44 is made of an ion semipermeable membrane.

[0057] See also Figure 6 The semipermeable membrane 44 can selectively prevent a single or multiple ions from passing through the semipermeable membrane and entering the universal nutrient solution.

[0058] It should be noted that, for example, leafy vegetables require more N, and a special nutrient solution containing N can be set to pass into the inner channel 31, and a general nutrient solution can be placed in the box 41. The semipermeable membrane 44 can choose to prevent N ions from passing through, which can promote the growth of leaves; crops that need to bloom and bear fruit require special K and Ca, and a special nutrient solution containing K and Ca can be set to pass into the inner channel 31, and the semipermeable membrane 44 can choose an ion membrane that prevents K and Ca from passing through, which can improve the quality of the fruit. The ratio of the general nutrient solution and the nutrient solution with special ingredients can be appropriately adjusted through the regulating component 5.

[0059] In this embodiment, a sealing ring is fixedly connected to the top of the outer wall of the inner metal support mesh 32 .

[0060] See also Figure 7 The gravity generated by the placement tray 33 and the crops inside it pushes the inner metal support mesh 32 toward the semipermeable membrane 44, causing the sealing ring to deform and seal the top of the contact surface between the inner metal support mesh 32 and the semipermeable membrane 44, preventing the special ingredient nutrient solution from passing over the semipermeable membrane 44 from the top of the semipermeable membrane 44 into the outer metal support mesh 45 and affecting the components of the general nutrient solution in the box 41.

[0061] It should be noted that the sealing ring is made of non-toxic and harmless elastic material, such as rubber, silicone, etc.

[0062] In summary, the present invention provides a soilless cultivation device for planting vegetables in an agricultural garden. According to the crop varieties, the general nutrient solution and the special component nutrient solution are added to the storage box 61 in advance, the crops are planted in the inner metal support net 32, and the inner metal support net 32 ​​is aligned with the mounting groove 43, the placement plate 33 is installed on the upper end surface of the support tray 42, and then the cultivation mechanism 2 is placed on the mounting plate 12, and the frame 1 is pushed to a position with suitable temperature and light, and the storage box 61 is controlled to pass the general nutrient solution to the second feed port 53 through the feeding main pipe 62 and the general nutrient delivery pipe 64, the general nutrient solution enters the inner cavity of the box body 41, and passes through the outer metal support net 45, the semipermeable membrane 44 and the inner metal support net 32, to provide nutrients for the crops in the inner metal support net 32, when the crops need special nutrients, the flow rate of the general nutrient delivery pipe 64 is increased, so that the liquid level in the box body 41 rises, and the floating plate 556 is driven by the buoyancy to drive the limit sliding rod 555 along the sliding The groove 54 moves upward, and at the same time, the screw sleeve 553 drives the second baffle 554 and the first baffle 551 to move upward along the placement groove 51 through the screw rod 552. When the second baffle 554 moves into the second feed port 53, the second feed port 53 is closed. At this time, the first baffle 551 moves out of the first feed port 52, and the special component nutrient solution in the special nutrient delivery pipe 63 passes through the first feed port 52 into the inner channel 31, and is then transported to each inner metal support net 32 ​​by the inner channel 31, and mixed with the universal nutrient solution in the inner metal support net 32 ​​to provide a new nutrient solution formula for the crops. When the liquid level in the box body 41 decreases, the floating plate 556 moves downward, so that the first baffle 551 and the second baffle 554 both move downward along the placement groove 51. At this time, the flow rate of the first feed port 52 gradually decreases, and the flow rate of the second feed port 53 gradually increases, so that the universal nutrient solution in the box body 41 is replenished in time to avoid excessive concentration of the special component nutrient solution, which causes seedling burn.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
