Description

Technical Field

[0001] The invention relates to the field of plant cultivation, in particular to a modular vertical liquid flow plant hydroponic unit, a hydroponic device and a hydroponic system. Background Art

[0002] In the field of plant cultivation, three-dimensional planting is a modern planting method that efficiently utilizes space, greatly improving the planting output per unit area of ​​land. At present, multi-layer racking is generally used for plant cultivation, and the cultivation tray is placed horizontally on the rack. When the nutrient solution is passed into the cultivation tray, in order to provide sufficient nutrients to the plants, the nutrient solution generally completely immerses the plant roots. At this time, the plant roots cannot obtain sufficient oxygen. In order to provide sufficient oxygen to the plants, the liquid level of the nutrient solution is controlled at a lower level, and the plants cannot obtain sufficient nutrients. However, in the existing vertical cultivation device, the plant roots cannot fully contact the nutrient solution, and the roots do not absorb enough nutrients. Summary of the invention

[0003] To this end, it is necessary to provide a modular vertical liquid flow plant hydroponic unit, a hydroponic device and a hydroponic system to solve the problem that in existing vertical cultivation devices, plant roots cannot fully contact the nutrient solution and the plant growth is uneven.

[0004] To achieve the above object, the present invention provides a modular vertical liquid flow plant hydroponic unit, comprising:

[0005] The installation body has a space inside to form a flow cavity, the top of the installation body is provided with a water inlet, and the bottom of the installation body is provided with a water outlet.

[0006] At least one planting plate, which is fixed on the side of the mounting body and is provided with planting holes arranged in an array; a guide core, which is fixed in the flow cavity, and a vertical flow channel is formed between the side of the guide core and the planting plate, and the guide core is provided with a plurality of transverse guide protrusions spaced from top to bottom on the side of the planting plate, and guide grooves are formed between adjacent guide protrusions, and the positions of the guide grooves correspond to the positions of the planting holes on the planting plate.

[0007] Furthermore, the side of the guide core facing the planting plate is wavy, the trough forms the guide groove, and the crest forms the guide protrusion. The cross section of the guide protrusion is arc-shaped.

[0008] Furthermore, the cross section of the guide protrusion is a polygon.

[0009] Furthermore, the guide protrusions and / or guide grooves are provided with horizontally extending grooves, and the nutrient solution is distributed on the surface of the guide core along the grooves, so that the nutrient solution is more evenly distributed on the side of the guide core.

[0010] Furthermore, the cross section of the groove is polygonal or arc-shaped, and the corners of the polygonal groove have an arc transition. The polygonal or arc-shaped groove has a large surface area, which is convenient for plant roots to attach. At the same time, when the nutrient solution is in the groove, it can continuously impact and turn, and fully contact with the air, ensuring that the plant roots are adequately supplied with oxygen. The arc transition at the corner avoids the accumulation of impurities at the corner, and can also facilitate the cleaning of the guide core.

[0011] Furthermore, a plurality of staggered and cross-arranged guide ribs are fixed on the side surface of the guide protrusion.

[0012] Furthermore, the planting plates are arranged on two opposite sides of the installation body, and the two opposite sides of the guide core are symmetrically provided with guide protrusions. Double-sided planting greatly increases the planting volume ratio, thereby increasing the yield per unit area.

[0013] Furthermore, the bottom of the installation body is provided with a plurality of fixing plates, the fixing plates are arranged at intervals in the water outlet, the two sides of the fixing plates are fixed to the installation body, the bottom of the guide core is provided with a plurality of mounting openings, the fixing plates match the mounting openings. The mounting openings match the top edges of the fixing plates, the setting of the fixing plates facilitates the fixing of the guide core, and at the same time, since the fixing plates are located at the bottom of the installation body, the flow of water in the vertical flow channel and the growth of plant roots will not be affected. In addition, the fixing plates are connected to the fixing frames on both sides, which can also play a role in strengthening the fixing frames.

[0014] Furthermore, the axis of the planting hole has an angle α with the horizontal plane, and the angle α ranges from 10° to 30°. The planting hole is tilted so that the installed planting cup is also tilted, the planting cup is not easy to fall, and the plant grows tilted upward.

[0015] Furthermore, a planting cup is provided in the planting hole, and a baffle is detachably fixed at the cup mouth of the planting cup. As the plant grows, the weight of the part of the plant on the outer surface of the planting plate becomes heavier, and the planting sponge in the planting cup may fall out of the planting cup. The baffle can block the planting sponge and effectively prevent the planting sponge in the planting cup from falling off.

[0016] Furthermore, the baffle is in an arc shape, an annular protrusion is fixed at the cup mouth of the planting cup, two oppositely arranged clamping plates are fixed on the annular protrusion, clamping blocks are fixed on both sides of the clamping plate, and there is a gap between the clamping block and the upper surface of the annular protrusion to form a bayonet, the baffle is located on the annular protrusion, and the two ends of the baffle are respectively embedded in the two bayonet. When the arc-shaped baffle blocks the planting sponge in the planting cup, it can also keep the cup mouth of the planting cup with a large opening to ensure the smooth growth of the plant, and the formation of the bayonet helps to quickly install and fix the baffle.

[0017] Furthermore, the two sides of the annular protrusion at the bottom of the card plate are hollowed out. The card plate, the annular protrusion and the planting cup are an integrated structure. When the baffle is embedded in the bayonet, there is a certain force between the card plate and the baffle. The setting of the hollow structure can reduce the rigidity between the card plate and the annular protrusion, and facilitate the installation of the baffle.

[0018] Furthermore, the planting plate is bent outward at the edge of the planting hole to form a ring-shaped placement ridge, the height of which gradually decreases from bottom to top, and the placement ridge is blocked and connected with the outer side of the planting plate cup. The placement ridge and the planting plate are an integrated structure, which simplifies the number of parts of the cultivation module and is convenient for operators to use. At the same time, the setting of the placement ridge also facilitates the tilting and fixing of the planting plate.

[0019] The hydroponic device comprises a support frame and a plurality of the above-mentioned modular vertical liquid flow plant hydroponic units, wherein the plurality of modular vertical liquid flow plant hydroponic units are fixed to each other in the vertical direction, and the modular vertical liquid flow plant hydroponic units are fixed to the support frame.

[0020] Furthermore, a connection frame is included, the bottom end of the installation body is provided with a connection groove, the inner side surface of the top of the installation body is provided with a connection protrusion, and in the two upper and lower adjacent modular vertical liquid flow plant hydroponic units, the top of the connection frame is embedded in the connection groove of the installation body of the upper modular vertical liquid flow plant hydroponic unit, and the bottom of the connection frame is arranged on the connection protrusion. The arrangement of the connection frame allows the two modular vertical liquid flow plant hydroponic units to be fixed more firmly.

[0021] The hydroponic system comprises a lighting panel and a plurality of hydroponic devices as described above. The plurality of hydroponic devices are arranged opposite to each other in pairs. A sliding rod is fixed between the tops of the two opposite hydroponic devices, and the lighting panel is slidably arranged on the sliding rod.

[0022] The above technical solution has the following beneficial effects:

[0023] 1. In the present invention, the nutrient solution flows from top to bottom on the side of the guide core. The grooves make the nutrient solution constantly bend and change direction during the flow process due to the effect of the guide protrusions on the surface of the guide core, so that the nutrient solution can fully absorb oxygen and ensure sufficient oxygen supply to the plant roots. At the same time, the guide grooves formed between the guide protrusions increase the contact area between the plant roots and the guide core, so that the roots can contact the nutrient solution in all directions, maintaining stable and uniform growth of the plants.

[0024] 2. During cultivation, the root system of the plant is located in the guide groove of the guide core, and the upper side of the guide protrusion plays a certain supporting role for the root system of the plant in the vertical direction, so that the root system of the plant always remains on the guide core, avoiding the problem that the roots cannot contact the nutrient solution, and when the nutrient solution flows from the guide groove to the guide protrusion, the flow rate of the nutrient solution slows down, which is conducive to the plant roots to fully absorb nutrients.

[0025] 3. The two light panels between the cultivation walls on the vertical flow cultivation device can adjust the lighting distance through the sliding rod to adapt to different growth stages of crops and improve light utilization. There is no need to set up a manual operation channel. You only need to move the light panel to one side to enter the operation. The planting volume ratio will be greatly improved. The device has no obstruction in the vertical direction, and the exchange of cold and hot air flows up and down is smooth. The heat generated by the lamps rises and is discharged directly, saving planting energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Example 1

[0043] See also Figure 1-7 This embodiment discloses a modular vertical liquid flow plant hydroponic unit, wherein the cultivation module includes at least one planting plate 2, a mounting body 1 and a guide core 3.

[0044] In this embodiment, the mounting body 1 is a flat box structure, the interior of the mounting body is hollow to form a flow cavity, the top of the mounting body 1 is provided with a water inlet 11, the bottom of the mounting body 1 is provided with a water outlet 12, the flow guide core 3 is fixed in the mounting body 1, the two opposite sides of the mounting body 1 are open, and the other two sides are closed, the planting plate 2 is fixed on the open side of the mounting body 1, and the bottom end of the open side of the mounting body 1 can be provided with a placement protrusion for the installation of the planting plate 2. After the planting plate 2 is placed on the open side, it can be fixed with fasteners such as screws. The inner side surfaces of the two planting plates 2 and the closed side surface of the mounting body enclose the flow cavity. The planting plate 2 is provided with planting holes 21 arranged in an array, and the planting holes 21 are provided with planting cups 4.

[0045] A vertical flow channel is formed between the side of the guide core 3 and the planting plate 2. The side of the guide core 3 facing the planting plate 2 is provided with multiple horizontal guide protrusions 34 from top to bottom. Guide grooves 33 are formed between adjacent guide protrusions 34. The position of the guide grooves 33 corresponds to the position of the planting holes 21 on the planting plate 2.

[0046] like Figure 3In this embodiment, the guide protrusion 34 and the guide core 3 are an integrated structure, and the side of the guide core 3 facing the planting plate 2 is wavy, wherein the trough forms the guide groove 33, and the crest forms the guide protrusion 34. At this time, the cross section of the guide protrusion 34 is an arc shape. Horizontally extending grooves 31 are provided on the surfaces of the trough and the crest (i.e., the guide groove 33 and the guide protrusion 34).

[0047] like Figure 6 In another embodiment, the guide protrusion 34 and the guide core 3 are an integrated structure, the guide protrusion 34 is a convex edge structure on the side of the guide core 3, the cross-section of the guide protrusion 34 is a trapezoidal structure, and there is a certain interval between the guide protrusions 34 to form a guide groove 33. The bottom surface of the guide groove 33 is a vertical plane, and a plurality of horizontally extending grooves 31 are distributed on the side of the trapezoidal guide protrusion 34.

[0048] The cross section of the groove 31 is polygonal or arc-shaped, and the corners of the polygonal groove 31 have an arc transition. The polygonal or arc-shaped groove 31 has a large surface area, which is convenient for plant roots to attach. At the same time, when the nutrient solution enters the groove 31, it can continuously impact and turn, and fully contact with the air to ensure sufficient oxygen supply to the plant roots. The arc transition at the corner avoids the accumulation of impurities at the corner, and can also facilitate the cleaning of the guide core 3. The specific polygonal shape can be a triangle, rectangle, trapezoid or pentagon, etc. In this embodiment, the cross section of the groove 31 is a rectangle.

[0049] In another embodiment, a plurality of staggered and cross-arranged guide ribs 35 are fixed on the side of the guide protrusion 34, such as Figure 7 In the figure, the cross-section of the guide protrusion 34 is triangular, the guide protrusion 34 and the guide core 3 are an integral structure, and staggered and crossed guide ribs 35 are fixed on the two sides of each guide protrusion 34. The guide ribs 35 are arc-shaped, and the guide ribs 35 can provide sufficient attachment points for plant roots and slow down the flow rate of the nutrient solution.

[0050] In this embodiment, during cultivation, the root system of the plant is located in the guide groove 33 (trough) 33 of the guide core 3, and the guide core 3 plays a certain supporting role for the root system of the plant in the vertical direction, so that the root system of the plant always remains on the guide core 3, avoiding the problem that the roots cannot contact the nutrient solution, and when the nutrient solution flows from the guide groove 33 (trough) 3 to the guide protrusion 34 (peak), the flow core has a flat surface, and the flow rate of the nutrient solution is slowed down, which is conducive to the plant roots to fully absorb nutrients.

[0051] In this embodiment, double-sided planting greatly increases the planting volume ratio, thereby increasing the yield per unit area. In this embodiment, the planting plate 2 has four rows of planting holes 21, and the two sides of the corresponding guide core 3 have four trough positions.

[0052] The bottom of the mounting body 1 is provided with a plurality of fixing plates 13, which are arranged at intervals in the water outlet 12, and the two sides of the fixing plates 13 are fixed to the mounting body 1. The bottom of the guide core 3 is provided with a plurality of mounting openings 32, and the fixing plates 13 match the mounting openings 32. The mounting openings 32 match the top edge of the fixing plates 13, and the setting of the fixing plates 13 facilitates the fixing of the guide core 3. At the same time, since the fixing plates 13 are located at the bottom of the mounting body 1, the flow of water in the vertical flow channel and the growth of plant roots will not be affected. In addition, the fixing plates 13 connect the fixing frames on both sides, which can also play a role in strengthening the fixing frames. In this embodiment, the top edge of the fixing plate 13 is provided with a fixing groove, and the two sides of the fixing groove are arranged obliquely, and the fixing groove is arranged opposite to the mounting opening 32.

[0053] The axis of the planting hole 21 has an angle α with the horizontal plane, and the range of the angle α is 10°-30°. The planting hole 21 is tilted so that the installed planting cup 4 is also tilted, the planting cup 4 is not easy to fall, and the plant grows upward. Specifically, the value of the angle α can be 10°, 15°, 20°, 25° or 30°. In this embodiment, the value of the angle α is 20°.

[0054] The planting plate 2 is bent outward at the edge of the planting hole 21 to form a ring-shaped placement ridge 22. The height of the placement ridge 22 gradually decreases from bottom to top, and the placement ridge 22 is blocked and connected with the outer side of the planting plate 2. The placement ridge 22 and the planting plate 2 are an integrated structure, which simplifies the number of parts of the cultivation module and is convenient for operators to use. At the same time, the setting of the placement ridge 22 also facilitates the tilting and fixing of the planting plate 2.

[0055] A baffle 41 is detachably fixed at the mouth of the planting cup 4. As the plant grows, the weight of the part of the plant on the outer surface of the planting plate 2 becomes heavier, and the planting sponge in the planting cup 4 may fall from the planting cup 4. The baffle 41 can be connected with the planting sponge to effectively prevent the planting sponge in the planting cup 4 from falling off.

[0056] In this embodiment, the baffle 41 is in an arc shape, and an annular protrusion 42 is fixed at the cup mouth of the planting cup 4. Two oppositely arranged clamping plates 43 are fixed on the annular protrusion 42. Clamping blocks 44 are fixed on both sides of the clamping plates 43. There is a gap between the clamping blocks 44 and the upper surface of the annular protrusion 42 to form a clamping opening 45. The baffle 41 is located on the annular protrusion 42, and the two ends of the baffle 41 are respectively embedded in the two clamping openings 45. When the arc-shaped baffle 41 blocks the planting sponge in the planting cup 4, it can also keep the cup mouth of the planting cup 4 with a large opening to ensure the smooth growth of the plant. The formation of the clamping opening 45 helps the baffle 41 to be quickly installed and fixed. Hollow structures are provided on both sides of the annular protrusion 42 at the bottom of the clamping plate 43. The clamping plate 43, the annular protrusion 42 and the planting cup 4 are an integrated structure. When the baffle 41 is embedded in the clamping port 45, there is a certain force between the clamping plate 43 and the baffle 41. The setting of the hollow structure can reduce the rigidity between the clamping plate 43 and the annular protrusion 42, and facilitate the installation of the baffle 41.

[0062] In the present invention:

[0063] The hydroponic device 8 and the hydroponic system are composed of a modular modular vertical liquid flow plant hydroponic unit 5, which is convenient for installation, disassembly and transportation. On the hydroponic device 8, the nutrient solution flows from top to bottom, solving the problems of overflow, algae growth, water blockage and the like in horizontal cultivation. The broken roots of plants can flow to the bottom layer with the water flow, and the roots can be cleaned in one step to solve the problem of roots blocking the water flow. The nutrient solution flows from top to bottom on the side of the guide core 3. The groove 31 makes the nutrient solution constantly encounter deflection and change of direction during the flow process.
