Description

Technical Field

[0001] The utility model belongs to the technical field related to plant cultivation, and particularly relates to a plant hydroponic experimental device. Background Art

[0002] Hydroponics is a new type of soilless cultivation method for indoor plants, also known as nutrient solution culture. The core of this method is to fix the plant rhizomes and allow the roots to grow naturally into the plant nutrient solution. This nutrient solution replaces natural soil to provide the plant with water, nutrients, temperature, and other growth factors, allowing the plant to grow normally and complete its entire life cycle. In plant laboratories, hydroponics is often used to observe plant growth changes, but actual hydroponic experiments still have the following disadvantages:

[0003] First, conventional hydroponic cultivation mostly fixes the plant roots in a planting basket, which is relatively fixed overall. This planting method will stabilize the position of the plant and keep it in that position. However, when the culture water level drops, it is easy for the plant roots to lose contact with water, making hydroponic operation impossible. Water needs to be added regularly, and water cannot be added at any time. The water level cannot be too much above the roots, which increases labor and power consumption.

[0004] Secondly, hydroponic cultivation of plants inevitably requires light. Conventional hydroponic experiments may add corresponding full-spectrum plant lights, but there is no intuitive auxiliary display effect on the impact of the angle and height of the light on the plants. Utility Model Content

[0005] The purpose of the utility model is to provide a plant hydroponic experimental device. By setting an incubator, floating bars, planting tubes, track components, lamps, and screws, the device solves the problems that the position of plants during hydroponics is too constant and cannot automatically change position with the water level, requiring continuous and timely water replenishment, increasing energy consumption and costs, and the lighting angle and height of plant hydroponics cannot be controlled.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a plant hydroponic experimental device, comprising an incubator, a track assembly, a screw, a lamp, a floating bar and a planting tube. U-shaped frames with equal spacing are fixed to both inner end walls of the incubator. A floating bar is clamped in the two opposing U-shaped frames. Planting holes with equal spacing are opened in the floating bar, and a planting tube is inserted into each planting hole.

[0008] The bottom of the planting tube is threadedly connected to a filter cup, and the outer periphery of the top of the planting tube is fixed with a limiting ring, and the limiting ring is located above the planting hole;

[0009] Track components are fixed on both short sides of the top of the incubator, and a screw rod is movably provided in each track component. The bottoms of the two screw rods rotate together and are connected to the upper end of the lamp, and a lamp tube is fixed in the inner cavity of the lamp.

[0010] Furthermore, a water inlet pipe is fixed through the upper portion of one end of the incubator, and a water outlet pipe is fixed through the lower portion of the other end of the incubator.

[0011] Furthermore, the openings of the U-shaped frames are all facing the central area of ​​the incubator, and a limiting rod is provided in the inner cavity of each U-shaped frame, and the bottom end of the limiting rod is fixed to the inner bottom of the incubator.

[0012] Furthermore, limiting holes are provided in both ends of the floating strip, and all planting holes on the same floating strip are located between the two limiting holes. The two ends of the floating strip are respectively placed in the inner cavities of two relatively U-shaped frames and are sleeved on the outside of the limiting rod through the limiting holes.

[0013] Furthermore, a clamping ring is fixed in the inner cavity of the planting tube, a threaded head is fixed outside the bottom port of the planting tube, a threaded groove is provided in the upper port of the filter cup, and the threaded head is screwed into the threaded groove.

[0014] Furthermore, the outer circumference and bottom of the filter cup are both provided with through holes distributed at equal intervals.

[0015] Furthermore, the track assembly includes two symmetrical arch rails, and track grooves are provided on the opposite surfaces of the two arch rails. Balls are slidingly arranged in the track grooves of the two arch rails, and the screw is threadedly connected to the ball. Nuts are threadedly screwed on the screws outside the upper and lower arc surfaces of the arch rails.

[0016] The utility model has the following beneficial effects:

[0017] The utility model solves the problem that the position of plants in hydroponics is too constant and cannot be automatically changed with the water level, and needs to be constantly replenished with water in a timely manner, which increases energy consumption and cost by arranging an incubator, floating bars and planting tubes. The hydroponic plants are placed in the corresponding planting tubes, and the planting tubes are then placed in the planting holes in the floating bars. Finally, the floating bars are placed on the surface of the water body in the incubator. The floating bars can float on the water body, and the ends of the floating bars are restricted in the corresponding U-shaped frames and will not shake at will. Then, during the process of hydroponics of plants, the floating bars automatically change their position with the height of the water level, ensuring that the roots of the plants can always be in contact with the water body. There is no need to replenish water regularly, and only some nutrient solution and water need to be added occasionally, which saves energy consumption and cost.

[0018] The utility model solves the problem of uncontrollable lighting angle and height of plant hydroponics by setting a track assembly, a lamp and a screw; the ball and the screw can move in the track assembly in an arc state, thereby changing the illumination angle of the lamp at the bottom of the screw, and the screw can also be screwed up and down on the inner thread of the ball, so that it can change the height of the lamp, thereby changing the corresponding lighting angle and height according to actual needs to form a comparative experiment.

[0019] The utility model adopts an independent planting tube and a filter cup to hydroponically cultivate a single plant, so that the cultivation status information can be displayed more conveniently, and the plant can be quickly taken out without damaging the rhizomes. In addition, the rhizomes of adjacent plants will not be entangled with each other and will not affect each other. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] See also Figure 1-7 As shown, the utility model is a plant hydroponic experimental device, comprising an incubator 1, a track assembly 2, a screw 3, a lamp 4, a floating bar 5 and a planting tube 6. Equidistantly distributed U-shaped frames 103 are fixed to both inner end walls of the incubator 1. A floating bar 5 is commonly clamped in the two opposing U-shaped frames 103. Equidistantly distributed planting holes 502 are opened in the floating bar 5, and a planting tube 6 is inserted into each planting hole 502.

[0032] The incubator 1 is filled with a large amount of water and the required nutrient solution, with the liquid level not exceeding that of the U-shaped frame 103. Subsequently, plant seedlings are planted in the planting tube 6, which is then inserted into the planting hole 502 in the floating strip 5. Finally, the floating strip 5 is floated on the surface of the water in the incubator 1.

[0033] The bottom of the planting tube 6 is threadedly connected to a filter cup 602, and a limit ring 601 is fixed to the outer periphery of the top of the planting tube 6, and the limit ring 601 is located above the planting hole 502;

[0034] A filter cup 602 is provided at the bottom of the planting tube 6, allowing water in the incubator 1 to flow into the filter cup 602 and contact the rhizomes in the planting tube 6, thus achieving hydroponic cultivation. The planting tube 6 is also restrained above the planting hole 502 by a limiting ring 601, preventing it from falling into the water.

[0035] Track assemblies 2 are fixed to both short sides of the top of the incubator 1. A screw rod 3 is movably provided in each track assembly 2. The bottoms of the two screw rods 3 rotate together to connect to the upper end of the lamp 4. A lamp tube 401 is fixed in the inner cavity of the lamp 4.

[0036] The track assembly 2 is an arched structure, and the screw 3 can perform an arc operation in the track assembly 2, so that the lamp 4 connected to the bottom of the screw 3 changes the lighting angle. The lamp tube 401 generates a light source, and a full-spectrum plant lamp can be used to facilitate observation of the state of plants under different lighting angles.

[0037] A water inlet pipe 101 is fixed through the upper portion of one end of the incubator 1, and a water outlet pipe 102 is fixed through the lower portion of the other end of the incubator 1;

[0038] The water inlet pipe 101 is used to add water and nutrient solution into the incubator 1 , and can also be added directly from the top of the incubator 1 . The water outlet pipe 102 is used to assist in draining the water in the incubator 1 .

[0039] The openings of the U-shaped frames 103 are all facing the center area of ​​the incubator 1. A limiting rod 104 is provided in the inner cavity of each U-shaped frame 103, and the bottom end of the limiting rod 104 is fixed to the inner bottom of the incubator 1;

[0041] When placing the floating strip 5, first insert the two ends of the floating strip 5 into the two opposite U-shaped frames 103, then match the limiting hole 501 with the limiting rod 104, move the floating strip 5 down so that it is located on the water surface, and at the same time, the floating strip 5 is sleeved on the outside of the limiting rod 104 through the limiting hole 501, realizing a double limiting operation, so that the floating strip 5 can only float with the water body, but cannot move at will. The floating strip 5 can only be raised and lowered, and cannot be displaced laterally.

[0042] A clamp ring 603 is fixed in the inner cavity of the planting tube 6, a threaded head 604 is fixed to the outside of the bottom end of the planting tube 6, a threaded groove 6021 is provided in the upper end of the filter cup 602, and the threaded head 604 is screwed into the threaded groove 6021;

[0043] The design of the restraining ring 603 helps stabilize the stem of the plant, and the root is located in the filter cup 602 , and the filter cup 602 and the planting tube 6 are fixed by screwing the thread head 604 and the thread groove 6021 .

[0044] The outer circumference and bottom of the filter cup 602 are both provided with through holes 6022 distributed at equal intervals. The provision of the through holes 6022 helps the water in the incubator 1 to enter the filter cup 602, providing sufficient moisture supply to the plants.

[0045] The track assembly 2 includes two symmetrical arched rails 201, and track grooves 202 are formed on the opposite surfaces of the two arched rails 201.

Nuts 302 are threadedly screwed onto the screw rods 3 on the outer sides of the upper and lower arc surfaces of the arched rails 201.

[0046] The arched rail 201 is fixed to the upper end of the incubator 1, and then the ball 301 can move in an arc in the track groove 202, thereby driving the screw 3 to move and changing the illumination angle of the lamp 4. After determining the position of the screw 3, the upper and lower nuts 302 approach each other until they contact and lock with the arched rail 201, so that the screw 3 no longer shakes. Secondly, the screw 3 can also rotate and rise and fall on the inner thread of the ball 301 to change the height of the lamp 4.

[0047] The specific working principle of the present invention is as follows: first, the filter cup 602 and the planting tube 6 are fixed by screwing the thread head 604 and the thread groove 6021, and then the plant seedlings are placed in the planting tube 6, the stem of the plant is located in the binding ring 603, and the root is located in the filter cup 602.
