Description

Technical Field

[0001] The invention relates to the field of agricultural planting, and in particular to an air-column type mist-cultivation planting trough that is inflated with air and injected with water. Background Art

[0002] Aerosol cultivation (mist farming) is a new soilless cultivation method that uses a nutrient solution sprayed onto the roots of plants while they are suspended in the air, resulting in superior crop growth compared to other cultivation methods. Currently, the three most common aeroponic cultivation methods in China are column cultivation, tower cultivation, and trough cultivation. Their cultivation facilities are all constructed using a support frame and extruded panels. Trough cultivation uses universal angle steel frames inlaid with extruded foam panels or factory-formed integrated foam troughs. However, these methods have issues such as large transportation volume, complex construction processes, and high costs.

[0003] Specific data of traditional trough cultivation: such as the transport volume of universal angle steel frame + foam extruded board (for example: the transport volume of 100m trough is about 2.5m 3 ), construction time (e.g., 3-5 people / day), and material costs (e.g., approximately 80-120 yuan per meter). Foam materials are prone to aging (with a service life of only 1-2 years), have poor weather resistance (releasing harmful substances at high temperatures), and cannot be flexibly tailored to size, limiting their application in complex terrain. Existing aeroponic cultivation facilities lack a "lightweight and foldable" design, making them unsuitable for scenarios such as temporary planting and post-disaster agricultural reconstruction. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides an aerated and water-injected air column mist farming planting trough, including a planting trough body and an X-frame. A trough cover is installed on the upper end face of the planting trough body, and slot holes are symmetrically opened on the front and rear ends of the upper end face of the trough cover. A plurality of X-frames are installed above the slot holes from left to right, and the X-frames are connected by cross bars. A climbing net is arranged on the inner end of the X-frame, and a water hose with laser holes is installed at the bottom of the planting trough body. A liquid supply pipe is installed on the right end face of the laser hole water hose.

[0005] Preferably, the planting trough body is composed of a plurality of 10-12 strands of opaque milky white co-extruded film air column coils, and the diameter of the air column unit after inflation is 1.5-3.5 cm.

[0006] Preferably, a 2-4 mm heat-sealed seam is provided between the air columns, and three folds are designed on the air column coil for folding the coil into a planting trough with a width of 0.6 m and a depth of 0.4 m, the length of which can be flexibly cut.

[0007] Preferably, the diameter of the slot holes 12 of the slot cover is 2.5-3 cm, the slot hole spacing is 0.25-0.3 m, and the row spacing is 0.4 cm.

[0008] Preferably, the trough cover and the planting trough body are integrally connected, and the X frame is made of fiberglass.

[0009] Preferably, the planting trough body is symmetrically provided with side frames, the side frames are made of alloy, a plurality of latches are installed on the bottom of the side frames from front to back, a connecting frame is installed on the upper end surface of the side frames, and an indicator sign is installed on the upper end surface of the connecting frame.

[0010] Preferably, lighting lamps are installed symmetrically on the inner ends of the cross bars.

[0011] Technical effects and advantages of the present invention:

[0012] 1. The present invention adopts an opaque milky white co-extruded film structure to meet the light-shielding requirements and prevent the black material from absorbing heat in the sun, causing the air pressure in the air column to increase and explode, and the temperature to be too high to affect the growth of crop roots.

[0013] 2. The present invention adopts co-extruded film as a lightweight material, which is convenient for installation and processing anytime and anywhere, solving the problems of current planting facilities being constructed by supporting frames and extruded boards, which have large transportation volume, complicated construction process, and high cost.

[0014] 3. For the first time, "opaque milky white co-extruded film air columns" are used in fog farming planting troughs, solving the problems of shading, heat insulation and lightweighting at the same time; the integrated design of laser-perforated water hoses and air column structures realizes the integration of nutrient solution atomization and trough support.

[0015] Compared with the existing technology, the present invention breaks through the transportation and installation bottlenecks of traditional fog farming facilities through material innovation (co-extrusion film formula) + structural innovation (air column modularization). Its technical solution is not easy to think of by those skilled in the art. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The present invention is presented for purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations will be apparent to those skilled in the art. The invention is selected and described in order to better illustrate the principles and practical applications of the invention and to enable those skilled in the art to understand the invention and design various inventions with various modifications suitable for specific applications.

[0021] See also Figures 1 to 3 The present invention provides an aerated and water-injected air column mist farming planting trough, comprising a planting trough body 1 and an X-frame 2. A trough cover 11 is installed on the upper end face of the planting trough body 1, and slot holes 12 are symmetrically opened on the front and rear ends of the upper end face of the trough cover 11. A plurality of X-frames 2 are installed above the slot holes 12 from left to right, and the X-frames 2 are connected by a cross bar 13. A climbing net 14 is arranged on the inner end of the X-frame 2, and a laser-perforated water hose 15 is laser-perforated at the bottom of the planting trough body 1. A liquid supply pipe 16 is installed on the front end face of the laser-perforated water hose 15. The planting trough body 1 is composed of multiple 10-12-wire opaque milky white co-extruded film air column 17 coils. The diameter of the air column 17 unit after inflation is 1.5-3.5 cm. When working, after taking the customized coil, inflate it according to the length of the site, and then fold the sheet into a trough shape according to the folding point. The trough cover 11 part is fixed to the other trough with a clip, heat-sealed or pasted with outdoor tape to form a planting trough. The laser perforated water belt 15 is laid in the groove and can be used for the aeroponic cultivation of melons, fruits and tomatoes.

[0022] Co-extrusion film material composition: It is clearly co-extruded by polyethylene (PE) + calcium carbonate filler + UV absorber, of which the calcium carbonate content accounts for 20-30%, achieving a shading rate ≥ 90% and a thermal conductivity coefficient ≤ 0.3W / (m·K) (better than the thermal conductivity of traditional black plastic film 0.5W / (m·K)).

[0023] Air column pressure resistance parameters: air pressure range after inflation is 0.05-0.1MPa, and the load-bearing capacity of a single air column is ≥5kg (ensuring that the trough can bear the weight of the nutrient solution and crops).

[0024] A 2-4 mm heat-sealed seam is provided between the air columns 17 , and three folds are designed on the coil of the air column 17 for folding the coil into a planting trough body 1 with a width of 0.6 m, a depth of 0.4 m, and a length that can be flexibly cut.

[0025] The diameter of the slot holes 12 of the slot cover 11 is 2.5-3 cm, the spacing between the slot holes 12 is 0.25-0.3 m, and the row spacing is 0.4 cm.

[0026] The trough cover 11 is integrally connected to the planting trough body 1. The X-frame 2 is made of fiberglass. When inflated, the cover simultaneously inflates to form a pressurized air column 17, providing support for crop cultivation. To prevent the planting trough from being too light, a combination of air and water filling can be used. By partially filling the trough with water, the trough body has a certain weight to provide wind resistance.

[0027] The planting trough body 1 is symmetrically provided with side frames 18, which are made of alloy. A plurality of pins 19 are installed on the bottom of the side frame 18 from front to back. A connecting frame 21 is installed on the upper end face of the side frame 18, and an indicator board 22 is installed on the upper end face of the connecting frame 21. When working, the side frames 18 are connected to the left and right sides of the planting trough body 1 through the pins 19, thereby positioning and fixing the planting trough body 1, further improving its stability. The planted plants are marked on the indicator board 22 for easy viewing.

[0028] The inner end of the crossbar 13 is symmetrically mounted with a lighting lamp 23. When in operation, at night, the lighting lamp 23 provides light, making it easy to see the growth of the plants and providing a certain light source for the photosynthesis of the plants at night.

[0029] Example

[0030] Anti-leakage design: A silicone sealing groove (width 5-8mm) is added at the connection between the trough cover and the planting trough body, and combined with the heat sealing process, the nutrient solution leakage rate is ≤0.5%.

[0031] Temperature control solution: Embed a thermally conductive silicone strip (2-3mm in diameter) in the air column interlayer and connect it to an external water cooling circulation system to control the internal temperature of the air column at 20-25°C (10-15°C lower than traditional black materials during high summer temperatures).

[0032] Optimization of nutrient solution circulation: The hole diameter of the laser-perforated water hose is 0.3-0.5mm, the hole spacing is 10-15mm, and it is combined with the pressure regulating valve of the liquid supply pipe (adjustment range 0.2-0.5MPa) to achieve a droplet size of 50-100μm (optimal particle size for crop absorption).

[0033] Inflation process steps

[0034] Step 1: Use a micro air pump (power 50-100W) to inflate the air column through the inflation nozzle. Stop when the air pressure reaches 0.08MPa (use a matching air pressure gauge for real-time monitoring).

[0035] Step 2: Use a heat sealing machine to perform secondary heat sealing on the air column interface (temperature 180-200℃, pressure 0.2MPa, time 5-8 seconds) to ensure airtightness.

[0036] Crop cultivation parameters

[0037] Planting density of melon crops (such as cucumbers): 8-10 plants per square meter, with a slot spacing of 0.3 meters;

[0038] Planting density of nightshade crops (such as tomatoes): 12-15 plants per square meter, with a slot spacing of 0.25 meters;

[0039] The height of the matching hanging vine climbing frame is 2.2-2.4 meters for melon crops and 1.8-2.0 meters for eggplants.

[0040] Comparative experimental data

[0041] Under the same greenhouse conditions (temperature 25±2°C, humidity 60±5%), tomatoes were grown using the planting troughs of the present invention and traditional foam troughs. The monitoring data for three consecutive months are as follows:

[0042] The present invention group: single plant yield 3.2kg, root disease incidence ≤5%;

[0043] Traditional group: single plant yield 2.5kg, root disease incidence rate 15-20%.

[0044] Expand application scenarios

[0045] "Removable side frame" design: The side frame is connected to the planting trough body through a quick-release buckle (not fixed with a pin), which is suitable for soilless cultivation scenarios (such as balcony agriculture and rooftop farms) and can be fixed without being inserted into the ground.

[0046] Comparison of technical effects

[0047] Comparison Dimension The present invention Traditional foam trough cultivation Transport volume <![CDATA[0.1m after compression per 100m 3 > <![CDATA[2.5m 3 ]]> Construction hours 1 person / day (modular installation) 3-5 people / day Material costs 40-60 yuan per meter 80-120 yuan Service life 5-8 years (anti-aging co-extrusion film) 1-2 years Crop root temperature 20-25℃ (controllable) 30-40℃ (high temperature in summer) Nutrient solution utilization rate ≥95% (precise spraying of droplets) 70-80% (serious loss)

[0048] During the specific work, an air pump air pipe is used to insert the air channel of the air column 17, so that compressed air of a certain pressure enters each air column 17. Many air columns 17 are combined to form a sheet with expansion pressure and folded into a planting trough. When the air column 17 coil is produced and processed, a mold is used to make the slot holes 12 and the indentation pressure points. The spacing between the slot holes 12 and the size of the holes are determined according to the planting requirements. After the inflation operation, the trough cover 11 is fastened and fixed to the trough body with a clip or other method to make the trough relatively sealed to prevent the nutrient solution from spraying and splashing.
