Description

Modular vertical liquid flow plant hydroponic unit, hydroponic device and hydroponic system

technical field

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 technique

In the field of plant cultivation, three-dimensional planting is a modern planting method with efficient use of space, which greatly improves the planting output per unit area of land. At present, multi-layer erection is generally used for plant cultivation, and the cultivation trays are placed horizontally on the layers. on the shelf. When the cultivation tray is fed with nutrient solution, in order to provide sufficient nutrients to the plants, the nutrient solution generally completely submerges the roots of the plants. At this time, the roots of the plants 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, plants cannot obtain sufficient nutrient elements, and in existing vertical cultivation devices, plant roots cannot fully contact the nutrient solution, and the nutrient absorption of the roots is insufficient.

Contents of the invention

Therefore, it is necessary to provide a modular vertical liquid flow plant hydroponic unit, a hydroponic device and a hydroponic system to solve the problems of the existing vertical cultivation device, that the root system of the plant cannot fully contact the nutrient solution, and the plant grows unevenly.

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

The installation body has a space inside the installation body 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,

At least one planting plate, the planting plate is fixed on the side of the installation body, and the planting holes arranged in an array are arranged on the planting plate; the flow guide core is fixed in the flow cavity, and the flow guide core A vertical flow channel is formed between the side of the core and the planting board, and the side of the guiding core facing the planting board is provided with a plurality of transverse guide protrusions at intervals from top to bottom, and a guide tube is formed between adjacent guide protrusions. Groove, the position of the diversion groove corresponds to the position of the planting hole on the planting plate.

Further, the side of the guide core facing the planting board is wavy, the troughs form the guide grooves, and the crests form the guide protrusions. The cross section of the diversion protrusion is arc-shaped.

Further, the cross-section of the guide protrusion is polygonal.

Further, horizontally extending grooves are provided on the flow guide protrusion and/or the flow guide groove. The nutrient solution is distributed on the surface of the flow guide core along the groove, so that the nutrient solution is more evenly distributed on the side of the flow guide core.

Further, the cross section of the groove is polygonal or arc-shaped, and the corners of the groove with polygonal cross-section are arc-shaped. 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 enters the groove, it can continuously impact, turn, and fully contact with the air to ensure sufficient oxygen supply for the plant root system. The arc transition at the center avoids the accumulation of impurities at the corners, and also facilitates the cleaning of the flow guide core.

Further, a plurality of misaligned and intersecting flow guiding ribs are fixed on the side of the flow guiding protrusion.

Further, the planting boards are provided on opposite sides of the installation body, and diversion protrusions are symmetrically arranged on opposite sides of the diversion core. Double-sided planting greatly increases the planting volume ratio, thereby increasing the output per unit area.

Further, the bottom of the mounting 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 plate are fixed with the mounting body, and the bottom of the guide core is provided with a plurality of mounting plates. port, the fixed plate matches the mounting port. The installation port is matched with the top edge of the fixed plate. The setting of the fixed plate facilitates the fixing of the diversion core. At the same time, because the fixed plate is located at the bottom of the installation body, it will not affect the flow of water in the vertical flow channel and the growth of plant roots. In addition, the fixed plate is connected The fixed frames on both sides can also play a role in strengthening the fixed frame.

Further, the axis of the planting hole has an included angle α with the horizontal plane, and the included angle α ranges from 10° to 30°. The planting holes are arranged obliquely so that the installed planting cups are also inclined, the planting cups are not easy to fall, and the plants grow obliquely upwards.

Further, a planting cup is arranged in the planting hole, and a baffle is detachably fixed at the mouth of the planting cup. As the plant grows, the weight of the plant on the outer surface of the planting board becomes heavier and heavier. It is possible that the planting sponge connected to the planting cup will fall from the planting cup. The setting of the baffle can block the planting sponge, effectively preventing Shedding of planting sponges in planting cups.

Further, the baffle plate is arc-shaped, and an annular protrusion is fixed at the mouth of the planting cup, and two opposite clamping plates are fixed on the annular protrusion, and two clamping plates are fixed on both sides of the clamping plate.

When the arc-shaped baffle blocks the planting sponge in the planting cup, it can also keep the opening of the planting cup with a large opening to ensure the smooth growth of the plant. The formation of the bayonet helps the quick installation of the baffle fixed.

Further, the ring-shaped protrusion is hollowed out on both sides of the bottom of the clamping plate. The clamping plate, the annular protrusion and the planting cup are integrated. When the baffle is embedded in the bayonet, there is a certain force between the clamping plate and the baffle. The setting of the hollow structure can reduce the rigidity between the clamping plate and the annular protrusion. Easy to install the baffle,

Further, the planting plate is bent outwards at the edge of the planting hole to form a ring-shaped placement lip, the height of the placement lip gradually decreases from bottom to top, and the placement lip is in contact with the outer surface of the planting plate cup . The placement convex edge and the planting board are integrally structured, 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 convex edge also facilitates the tilting and fixing of the planting board.
