Description

Technical Field

[0001] The invention relates to the field of plant cultivation, in particular to a modular cross-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 cross-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 cross-flow plant hydroponic unit, comprising:

[0005] An installation frame, wherein a water inlet is provided at the top of the installation frame, and a water outlet is provided at the bottom of the installation frame;

[0006] Two planting plates, each of which is provided with planting holes arranged in an array, are fixed on opposite sides of a mounting frame, the mounting frame and the planting plates enclose a flow cavity, the inner side of the planting plate is the inner side wall of the flow cavity, and the planting holes on the two planting plates are staggered.

[0007] Multiple guide plates are located in the flow cavity. The guide plates are fixed to the inner side of the planting plate. Each row of planting holes on the planting plate corresponds to a guide plate. The guide plates are located below each row of planting holes. The guide plates on the two relatively arranged planting plates are staggered and cross-arranged.

[0008] Furthermore, the guide plate is provided with a plurality of guide grooves at intervals, and the guide grooves correspond to the positions of the planting holes.

[0009] Furthermore, transverse guide ribs are provided in the guide groove, and the guide ribs are extended from the side of the guide groove to the center of the guide groove, and a plurality of guide ribs are cross-staggered.

[0010] The guide ribs are used to slow down the flow rate of the nutrient solution in the guide groove, allowing the roots to fully absorb the nutrient solution; the guide ribs can increase the attachment points of the plant roots in the guide groove, which is convenient for the fixation of the plant roots. In addition, the cross-staggered guide ribs can intercept part of the nutrient solution to avoid the complete water shortage of the plant roots in the event of a water supply failure, thus ensuring the normal growth of the plants.

[0011] Furthermore, the guide ribs are arc-shaped, which is helpful to slow down the flow speed of the nutrient solution.

[0012] 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.

[0013] Furthermore, the bottom surface of the guide groove is inclined from outside to inside and from top to bottom, the two sides of the guide groove are in arc transition, the bottom surface of the guide groove and the horizontal plane have an angle β, and the angle β is smaller than the angle α. The guide groove has a certain inclination angle, so that the nutrient solution can be continuously diverted downward, and the nutrient solution components in the guide groove can be continuously updated and replaced, preventing the nutrient solution from accumulating too much in the guide groove, so that the nutrient solution on each guide plate cannot fully flow, hindering the normal growth of plants.

[0014] Furthermore, the horizontal width of the guide plate is 3 / 5-4 / 5 of the horizontal width of the flow chamber. The horizontal width of the guide plate exceeds half of the mounting frame, so that the nutrient solution can continuously flow through the two opposite planting plates.

[0015] Furthermore, a planting cup is provided in the planting hole, a baffle is provided at the cup mouth of the planting cup, an annular boss is fixed at the cup mouth of the planting cup, two relatively arranged clamping plates are fixed on the annular boss, 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 boss to form a bayonet, the baffle is located on the annular boss, and the two ends of the baffle are respectively embedded in the two bayonet. As the plant grows, the weight of the part of the plant on the outer surface of the planting plate becomes heavier, and there is a possibility that the planting sponge in the planting cup will fall from the planting cup. The setting of the baffle can block and connect with the planting sponge, effectively preventing the planting sponge in the planting cup from falling off. The formation of the bayonet facilitates the rapid installation and fixation of the baffle.

[0016] The hydroponic device comprises a support frame and a plurality of the above-mentioned modular cross-flow plant hydroponic units, wherein the plurality of modular cross-flow plant hydroponic units are fixed to each other in a vertical direction, and the modular cross-flow plant hydroponic units are fixed to the support frame.

[0017] Furthermore, a connection frame is included, the bottom end of the installation frame is provided with a connection groove, the inner side surface of the top of the installation frame is provided with a connection boss, and in the two upper and lower adjacent modular cross-flow plant hydroponic units, the top of the connection frame is embedded in the connection groove of the installation frame of the upper modular cross-flow plant hydroponic unit, and the bottom of the connection frame is provided on the connection boss. The setting of the connection frame allows the two modular cross-flow plant hydroponic units to be fixed more firmly.

[0018] Furthermore, a diverter box is installed on the water inlet of the top modular cross-flow plant hydroponic unit, and a plurality of diverter holes are arranged at intervals on the bottom surface of the diverter box, and the position of each diverter hole corresponds to the position of each column of planting holes on the planting plate. The diverter box can store part of the nutrient solution, and the setting of the diverter holes facilitates the precise diversion of the nutrient solution, thereby achieving precise irrigation.

[0019] The hydroponic system comprises a lighting panel and a plurality of the above-mentioned hydroponic devices, wherein 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.

[0020] The above technical solution has the following beneficial effects:

[0021] 1. In the present invention, two planting plates are planted in a double-sided cross-type manner, which greatly increases the planting volume ratio, thereby improving the yield per unit area. The guide plate is fixed on the inner side of the planting plate. The staggered and cross-arranged guide plates can make the nutrient solution continuously bend and change direction during the flow process in the flow cavity, so that the nutrient solution flows evenly through each planting hole to achieve precise irrigation. At the same time, the nutrient solution can fully absorb oxygen during the continuous bend and change direction, ensuring that the plant roots are adequately supplied with oxygen. The setting of the guide groove is used to facilitate the growth of the plant roots, increase the contact area between the plant roots and the guide plate, allow the roots to have more contact with the nutrient solution, and ensure the stable growth of the plants. In addition, the guide plate plays a certain supporting role on the plant roots to a certain extent.

[0022] 2. The two light panels between the cultivation walls on the hydroponic system 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

[0037] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings. Example

[0038] See also Figure 1-5, the present embodiment is a modular cross-flow plant hydroponic unit, comprising a mounting frame 1, two planting plates 2 and a plurality of guide plates 3. In the present embodiment, the mounting frame 1 is a flat box structure with a space inside, a water inlet 11 is provided at the top of the mounting frame 1, and a water outlet 12 is provided at the bottom of the mounting frame 1;

[0039] The two opposite sides of the mounting frame 1 are open to form mounting sides, and the two planting plates 2 are respectively fixed on the mounting sides. Thus, the mounting frame 1 and the two planting plates 2 enclose a flow cavity, and the inner sides of the planting plates 2 constitute the side walls of the flow cavity. The planting plates 2 can be fixed to the mounting frame 1 by screw fasteners, or a boss can be formed on the mounting side, and the planting plates 2 can be fixed by snapping together with the snapping pieces.

[0040] The planting plates 2 are provided with planting holes 21 arranged in an array, and planting cups 5 are arranged in the planting holes 21. The planting holes 21 on the two planting plates 2 are staggered; the planting holes 21 arranged in an array are arranged in multiple rows and columns.

[0041] The guide plate 3 is fixed on the inner side of the planting plate 2. Each row of planting holes 21 of the planting plate 2 corresponds to a guide plate 3. The guide plate 3 is located below each row of planting holes 21. A plurality of guide grooves 31 are arranged at intervals on the guide plate 3. The guide grooves 31 correspond to the positions of the planting holes 21. The guide plates 3 on the two planting plates 2 are staggered and cross-arranged. The guide grooves 31 of the guide plate 3 are bent downward.

[0042] The guide plate 3 can be set as an integral structure with the planting plate 2, or a transverse installation slot can be set on the back of the planting plate 2, and one side of the guide plate 3 is inserted into the installation slot for fixation, thereby forming a detachable structure between the guide plate 3 and the planting plate 2.

[0043] 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 5 is also tilted, the planting cup 5 is not easy to fall, and the plant grows upward. In this embodiment, the value of the angle α is 20°.

[0044] In another implementation manner, the angle α is set to 10°.

[0045] In another implementation manner, the angle α is set to 30°.

[0046] An arc-shaped baffle 51 is provided at the mouth of the planting cup 5. An annular boss 52 is fixed at the mouth of the planting cup 5. Two oppositely arranged clamping plates 53 are fixed on the annular boss 52. Clamping blocks 54 are fixed on both sides of the clamping plates 53. There is a gap between the clamping blocks 54 and the upper surface of the annular boss 52 to form a bayonet 55. The baffle 51 is located on the annular boss 52, and the two ends of the baffle 51 are respectively embedded in the two bayonet 55. As the plant grows, the weight of the part of the plant on the outer surface of the planting plate 2 becomes heavier and heavier, and it is possible that the planting sponge in the planting cup 5 may fall from the planting cup 5. The baffle 51 can be blocked with the planting sponge to effectively prevent the planting sponge in the planting cup 5 from falling off. The formation of the bayonet 55 helps the baffle 51 to be quickly installed and fixed.

[0047] The guide plate 3 is arranged horizontally, and the bottom surface of the guide groove 31 is inclined from outside to inside and from top to bottom. The two sides of the guide groove 31 are arc-shaped transitions. The bottom surface of the guide groove 31 and the horizontal plane have an angle β, which is smaller than the angle α. In this embodiment, the inclination angle of the guide groove 31 is 14°. The guide groove 31 has a certain inclination angle, so that the nutrient solution can be continuously diverted downward, and the nutrient solution components in the guide groove 31 can be continuously updated and replaced, preventing the nutrient solution from accumulating too much in the guide groove 31, so that the nutrient solution on each guide plate 3 cannot flow fully, hindering the normal growth of plants.

[0048] In another implementation, the entire guide plate 3 may also be arranged to be tilted downward.

[0049] A plurality of arc-shaped guide ribs 32 are provided in the guide groove 31. The guide ribs 32 extend from the side of the guide groove 31 to the center of the guide groove 31. The plurality of guide ribs 32 are arranged in a cross-displaced manner. The guide ribs 32 are used to slow down the flow speed of the nutrient solution in the guide groove 31, so that the roots can fully absorb the nutrient solution; the guide ribs 32 can increase the attachment points of the plant roots in the guide groove 31, which is convenient for fixing the plant roots. In addition, the cross-displaced guide ribs 32 can intercept part of the nutrient solution, so as to avoid the plant roots being completely cut off from water when the water supply fails, thereby ensuring the normal growth of the plants.

[0050] In this embodiment, each guide groove 31 corresponds to four guide ribs 32, and the guide ribs 32 and the guide grooves 31 are an integrally formed structure. Specifically, the guide plate 3 can be set using injection molding, and the guide grooves 31 and guide ribs 32 and other structures can be molded at one time. In another implementation method, the guide ribs 32 are set to be pasted and fixed using waterproof adhesive, so that even if the guide ribs 32 are washed away, they can be quickly replaced.

[0051] In this embodiment, the vertical heights of the guide ribs 32 in the uniform guide groove 31 are equal. In another implementation mode, in order to adapt to the development of the roots of different plants, the heights of the plurality of guide plate ribs 32 can be set to be different. The guide ribs with higher heights can provide a larger attachment area for the plant roots.

[0052] In another embodiment, among the multiple guide ribs 32, the guide ribs close to the planting plate 2 can be set as vertical cylinders, which can conveniently guide the plant roots to grow downward, while the guide ribs 32 close to the outside are set as strip structures, which can intercept part of the nutrient solution in the guide groove 31.

[0053] In this embodiment, the horizontal width of the guide plate 3 is 3 / 5 of the horizontal width of the installation frame 1 .

[0054] In another embodiment, the horizontal width of the guide plate 3 is 4 / 5 of the horizontal width of the mounting frame 1. The horizontal width of the guide plate exceeds half of the mounting frame 1, so that the nutrient solution can continuously flow through the two opposite planting plates 2. Example

[0055] See also Figure 2 , 6 -9, this embodiment discloses a hydroponic device, including a support frame 7, a connecting frame 8 and a plurality of modular cross-liquid flow plant hydroponic units 6 of embodiment 1, wherein the plurality of modular cross-liquid flow plant hydroponic units 6 are fixed to each other in the vertical direction, and the modular cross-liquid flow plant hydroponic units 6 are fixed to the support frame 7.

[0056] Specifically, the bottom end of the mounting frame 1 of the modular cross-flow plant hydroponic unit 6 is provided with a connecting groove 13, and a diverter box 4 is installed on the water inlet 11 of the top modular cross-flow plant hydroponic unit 6. A plurality of diverter holes 41 are arranged at intervals on the bottom surface of the diverter box 4, and the position of each diverter hole 41 corresponds to the position of each row of planting holes 21 on the planting plate 2. The diverter box 4 can store part of the nutrient solution, and the arrangement of the diverter holes 41 facilitates the precise diversion of the nutrient solution, thereby achieving precise irrigation.

[0057] Specifically, the inner surface of the water inlet 11 of the mounting frame 1 forms a connecting boss, and the diverter box 4 is directly placed on the connecting boss; in another embodiment, the diverter box 4 can be fixed to the top of the mounting frame 1 by a fastener; Figure 2 As described, a downwardly recessed diversion groove is provided on the bottom surface of the diversion box, and the diversion groove is biased towards the uppermost row of the two planting plates 2. The diversion holes 41 are arranged at intervals at the bottom of the diversion groove. Therefore, with the cooperation of the guide plate 3, the nutrient solution starts from the diversion hole 41 and flows from top to bottom through each planting hole 21, providing nutrients for the roots of the plants in each planting hole 21.

[0058] The side of the diverter box 4 and the side of the top of the mounting frame 1 form a placement groove. In the two upper and lower adjacent modular cross-flow plant hydroponic units 6, the top of the connecting frame 8 is embedded in the connecting groove 13 of the mounting frame 1 of the upper modular cross-flow plant hydroponic unit 6, and the bottom of the connecting frame 8 is embedded in the placement groove. The setting of the connecting frame 8 allows the two modular cross-flow plant hydroponic units 6 to be fixed more firmly. Example

[0059] See also Fig.10 This embodiment discloses a hydroponic system, including a lighting panel 92 and a plurality of hydroponic devices 9 of embodiment 2. The plurality of hydroponic devices 9 are arranged opposite to each other in pairs, and a slide bar 91 is fixed between the tops of two opposite hydroponic devices 9, and the lighting panel 92 is slidably arranged on the slide bar 91.

[0060] In the present invention:

[0061] The hydroponic device 9 and the hydroponic system are composed of a modular modular cross-flow plant hydroponic unit 6, which is convenient for installation, disassembly and transportation. On the hydroponic device 9, the nutrient solution flows from top to bottom, solving the problems of overflow, algae growth, water blockage, etc. 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. In the process of the nutrient solution flowing from top to bottom in the modular cross-flow plant hydroponic unit 6, due to the cross-displaced guide plate 3, the nutrient solution is continuously deflected and redirected. When the nutrient solution flows through the guide groove 31 of the guide plate 3, it can fully contact the root system of the plant to ensure that the plant can fully absorb nutrients. The guide ribs 32 in the guide groove 31 can slow down the flow speed of the nutrient solution and provide sufficient attachment points for the root system of the plant, which is beneficial to the fixation of the plant and ensures the normal growth of the plant.
