Description

Technical Field

[0001] This utility model belongs to the field of cultivation device technology, and in particular relates to a multi-layer three-dimensional strawberry cultivation device. Background Technology

[0002] Strawberries are perennial herbaceous plants with brightly colored and fragrant fruits, making them popular with consumers worldwide. They consistently rank first in production among small berries. Elevated cultivation is a new cultivation method conducted in greenhouses, where strawberries are grown by constructing elevated cultivation beds of suitable height and width and evenly spreading cultivation substrate within them.

[0003] Compared to soil-based strawberry cultivation, elevated cultivation utilizes vertical space, saving land area and improving land use efficiency. Elevated cultivation also avoids ground-borne mold and soil-borne diseases, thus extending the strawberry's growth and harvesting cycle.

[0004] Traditional H-shaped and X-shaped cultivation racks can only grow a limited number of strawberries per unit area, resulting in low utilization of vertical space in greenhouses and low production efficiency. Multi-layered racks can cause varying degrees of shading, affecting the normal growth of strawberries. Furthermore, under elevated substrate cultivation, the temperature fluctuations in the strawberry root zone are significant, and the low temperatures during winter are detrimental to strawberry growth. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems and provide a multi-layer three-dimensional strawberry cultivation device with high utilization of three-dimensional space per unit area and without affecting the normal growth of strawberries. It includes a cultivation trough, a cultivation rack body that carries the cultivation trough, and a water supply device located above the cultivation trough.

[0006] There are two main cultivation racks arranged opposite each other. Each main cultivation rack has at least one parallel crossbar extending outward from both sides. The two parallel crossbars opposite each other of the two main cultivation racks are used to support the cultivation trough.

[0007] The water supply and irrigation device includes a main pipe and a branch pipe fixed to the outside of the main body of the cultivation rack. The main pipe and the branch pipe are connected and vertically arranged. The main pipe is connected to a water source, and the end of the branch pipe is connected to a drip irrigation tape, which is located above the cultivation trough.

[0008] Furthermore, the cultivation trough is equipped with a substrate, non-woven fabric, and a heating water pipe in sequence. The heating water pipe is located at the bottom of the cultivation trough, and its two ends are connected to a stainless steel water tank containing hot water through water pipes. The water circulation between the heating water pipe and the stainless steel water tank is realized through a water supply pump.

[0009] Furthermore, the main body of the cultivation rack is an "A"-shaped cultivation rack composed of two diagonal bars and multiple horizontal bars. Multiple parallel horizontal bars extend at equal intervals on the outside of each diagonal bar. Each parallel horizontal bar is set parallel to the horizontal bar, and its tail extends upward with anti-slip clips for limiting positioning to prevent the cultivation trough from sliding out.

[0010] Furthermore, the two opposing cultivation racks are supported by a cultivation trough via two horizontal bars at the top.

[0011] Furthermore, the main body of the cultivation rack has a mounting plate at the top horizontal bar, and the cultivation trough is placed on two opposite mounting plates.

[0012] Furthermore, each cultivation trough is equipped with a branch pipe. The main pipe and two straight pipes located on opposite sides of the main pipe are connected by a four-way connector. The end of each branch pipe is connected to a PVC pipe through a reducer. The end of the PVC pipe is connected to the drip irrigation tape through an internal threaded straight connector, an elbow, and a drip bypass valve in sequence.

[0013] Furthermore, each cultivation trough has at least one through hole at its tail end, and the tail end of each drip irrigation tape is fixedly connected to one through hole via a connector.

[0014] Furthermore, each crossbar is equipped with a powered LED fill light at its bottom.

[0015] Furthermore, the outer ends of the top crossbar and the parallel crossbar are all provided with telescopic crossbar extension rods, and the anti-slip clips are fixed bolts. The extended crossbar extension rods are fixed to the crossbar and the parallel crossbar by the fixed bolts.

[0016] Each crossbar extension bar is equipped with a powered LED fill light.

[0027] The following is a more detailed description of a multi-layer three-dimensional strawberry cultivation device of the present invention with reference to the schematic diagram, which illustrates the preferred embodiment of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0028] like Figure 1 As shown, a multi-layer three-dimensional strawberry cultivation device is provided, and multiple such devices are placed inside a greenhouse. The main structures of the multiple cultivation racks are identical. This embodiment will be described using one of them as an example.

[0029] The device includes a cultivation rack body 1, a cultivation trough 3, and an irrigation device.

[0030] refer to Figure 2 The main body 1 of the cultivation rack consists of two diagonal braces 11 and three horizontal braces 12, roughly in the shape of an "A". Of the three horizontal braces 12, one is located at the top of the two diagonal braces 11, and of the other two, one is located in the middle and the other is located slightly below the middle. The two diagonal braces 11 are connected and fixed by the three horizontal braces 12. Each diagonal brace 11 has three equally spaced parallel horizontal braces 13 extending outward from its outer perimeter. The parallel horizontal braces 13 are all parallel to the horizontal braces 12, and the six parallel horizontal braces 13 of the two diagonal braces 11 are set at the same horizontal height in pairs.

[0031] Each device includes two cultivation rack bodies 1 arranged opposite each other. The two cultivation rack bodies 1 have two parallel crossbars 13 arranged opposite each other at the same horizontal height and are used to support the cultivation trough 3. The tail end of each parallel crossbar 13 also extends upward with an anti-slip clip 14 to prevent the cultivation trough 3 from sliding out.

[0032] To improve the space utilization of the device, the present invention provides a mounting plate 7 fixed on the crossbar 12 at the top of the main body 1 of the cultivation rack, facing inwards. The two opposite mounting plates 7 can also support a cultivation trough 3, thereby improving the space utilization.

[0033] The cultivation trough 3 contains, from top to bottom, a cultivation substrate, non-woven fabric, and heating water pipes. The heating water pipes provide the necessary warmth when the strawberry substrate temperature fluctuates greatly in winter, and the heating system reduces power consumption, making it more energy-efficient and environmentally friendly.

[0034] Specifically, the heating water pipe is used to circulate hot water, and its two ends are connected to a stainless steel water tank through pipes. The stainless steel water tank is used to store hot water. When the substrate temperature is low, the water supply pump drives the hot water in the stainless steel water tank to flow through the heating water pipe and then back into the stainless steel water tank. When the hot water temperature drops to the temperature preset by the control box, the water in the stainless steel water tank is pumped to the outdoor unit of the air source heat pump for heating and then pumped back into the stainless steel water tank, thus working in a cycle.

[0035] The irrigation system includes a water supply device 2 and a drainage device 8.

[0036] refer to Figure 3 The water supply device 2 is located at the front of the main body 1 of the cultivation rack and is fixed to the main body 1 by adhesive or straps. It includes a main pipe 21 connected to the underground water source and branch pipes 22 connected to the main pipe 21. Both the main pipe 21 and the branch pipes 22 are PVC pipes with a diameter of 32mm. There are four main pipes 21 and six branch pipes 22. The bottom of the main pipe 21 is connected to the underground water source and is disconnected by a 32mm ball valve 28. The top of the main pipe 21 is connected to the two branch pipes 22 opposite to it and the main pipe 21 above it through a four-way valve 23, and so on.

[0037] The top of the main pipe 21 is connected to a drip irrigation tape 5 via a 32×20mm reducer 25, a 20mm PVC tee 24, an elbow 27, and a drip bypass valve 4. The other end of each branch pipe 22 is connected to a drip irrigation tape 5 via a 32×20mm reducer 25, a 20mm internal thread straight connector 26, an elbow 27, and a drip bypass valve 4. A drip irrigation tape 5 is installed above each cultivation trough 3 for drip irrigation inside the cultivation trough 3.

[0038] refer to Figure 4To ensure the fixed height of the drip irrigation tape 5, we set at least one through hole 31 at the end of each cultivation trough 3, and the end of each drip irrigation tape 5 is fixed to one of the through holes 31 by a connector 6. The two drip irrigation tapes 5 located above the cultivation trough 3 at the top are fixed to the two through holes 31 respectively.

[0039] The drainage device 8 is located at the tail end of the cultivation trough 3. The tail end of the cultivation trough 3 is provided with a 25mm water outlet. The 25mm water outlet is directly connected to a 25mm water pipe via a 25mm elbow to a 32mm main drainage pipe (which is roughly the same as the structure of the water supply device). The main drainage pipe is connected to the water outlet pipe of each layer with a 32mm four-way connector. The main drainage pipe discharges the back liquid from underground.

[0040] Additionally, it should be noted that to prevent the multiple layers of cultivation troughs 3 from interfering with each other's lighting, we have installed an LED supplemental light at the bottom of each horizontal bar 12. These supplemental lights are connected to a power source via electrical wiring, and the power wiring is waterproofed (e.g., with waterproof paint or additional conduit) to prevent damage to the wiring insulation and potential electrical leaks, thus avoiding safety hazards. The supplemental lighting solves the problem of insufficient light for strawberries in the multi-layered cultivation troughs and will not affect their normal growth.

[0041] Alternatively, the length of all parallel crossbars 13 can be extended so that the cultivation troughs 3 of different layers are staggered in the vertical direction, which can effectively prevent the cultivation racks 3 located on higher floors from affecting the lighting of the cultivation racks 3 located on lower floors.

[0042] Furthermore, extendable extension rods 15 are provided on both sides of the top horizontal bar 12 and at the outer ends of the extended parallel horizontal bar 13 (excluding the bottom parallel horizontal bar), and anti-slip clips 14 are provided as fixing bolts. The extension rods 15 are fixed to the parallel horizontal bar 13 through threaded holes pre-drilled on their surfaces and the surfaces of the parallel horizontal bar 13, with the fixing bolts. The extension rods 15 are used to fix the LED supplementary lights, and the fixing method can be magnetic fixing or bolt-on detachable fixing.

[0043] The above are merely preferred embodiments of this utility model and do not constitute any limitation on this utility model. Any equivalent substitutions or modifications made by those skilled in the art to the technical solutions and contents disclosed in this utility model without departing from the scope of the technical solutions of this utility model shall still fall within the protection scope of this utility model.
