Description

Technical Field

[0001] This invention relates to the field of agriculture, and more specifically, to an intelligent and environmentally friendly backyard cultivation device. Background Technology

[0002] Vegetables are a primary source of nutrition for people. Many commercially available vegetables have little to no pesticide residue on their surface, leading people to consider growing their own vegetables in their own yards to ensure they are free from pesticide and other health concerns. Some people have even set aside a few square meters under their eaves, covering them with plastic film for vegetable cultivation. This has resulted in the development of numerous low-cost, easy-to-operate, and small-scale vegetable cultivation facilities, utilizing yards and houses for vegetable growing.

[0003] Currently, although there are several types of small greenhouses suitable for garden horticulture on the market, these facilities have the following problems: first, the angle of sunlight on vegetables is uneven; second, the nutrient solution droplets are not recycled after formation; and third, the planting area required is large and the variety of plants is limited. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide an intelligent and environmentally friendly backyard cultivation device that can grow a variety of vegetables in a small area of ​​land, reuse nutrient solution to achieve environmental protection, and use soilless cultivation without being restricted by natural conditions, so that the vegetables can be exposed to sufficient sunlight in every part.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A smart and environmentally friendly backyard cultivation device includes a storage tank, a return pipe, and a spiral cultivation pipe. The storage tank is fixedly connected to the return pipe, which is connected to the upper end of the spiral cultivation pipe. The lower end of the spiral cultivation pipe is connected to the storage tank. The device is characterized by further including a water storage hopper, a circuit system, a drive control system, a vibration motor, and a braking assembly. The circuit system has at least one open circuit point under normal conditions to maintain an open circuit state. The inner wall of the water storage hopper is inclined so that water on the inner wall can automatically slide into the bottom of the hopper under gravity and collect. A braking assembly is installed on the outside of the water storage hopper. The two ends of the water storage hopper are detachably connected to the inner wall of the spiral cultivation pipe. The inner wall of the water storage hopper has two metal contacts for circuit operation. The system has a circuit breaker point; under normal conditions, the water level inside the water tank is lower than the metal contact at the highest position to keep the circuit open; when the water level inside the water tank is higher than the metal contact at the highest position, the circuit is closed; the drive control system is electrically connected to the circuit system to obtain the on / off state of the circuit system; the braking assembly is electrically connected to the drive control system to be controlled by the drive control system to start and stop; the movement range of the braking assembly covers the location of the water tank to lift and drain the water tank; the vibration motor of the braking assembly is electrically connected to the drive control system to be controlled by the drive control system to start and stop; the output end of the vibration motor is connected to the vibration plate to drive the return pipe and spiral cultivation pipe to vibrate.

[0007] Furthermore, the circuit system includes a power supply, a resistor, an ammeter, two metal contacts, and a drive control system. The positive terminal of the power supply is electrically connected to the metal contact at one end of the water storage tank, and the metal contact at the other end of the water storage tank is electrically connected to the resistor. When the water storage tank is full of water, it forms a horizontal surface. When the metal contacts at both ends are exposed to water, they conduct electricity and connect the circuit. When there is no water in the water storage tank or the water level does not reach the height of the metal contacts, the circuit is open. The resistor is electrically connected to the ammeter, the input terminal of the drive control system is electrically connected to the signal output terminal of the ammeter, and the ammeter is electrically connected to the negative terminal of the power supply to form a complete circuit system.

[0008] Furthermore, the system also includes a floating component, which serves as another break point in the circuit system. The ammeter in the circuit system is connected to the energized part of the floating component. A metal contact is provided at the upper end of the floating component. When the floating component slides downward and the drop height causes the metal contact to contact the wire, the circuit is connected. If the floating component is too low or too high, the metal contact will not contact the wire, and the circuit is broken. Finally, the energized part of the floating component is connected to the negative terminal of the power supply.

[0009] Furthermore, the system also includes a water level signal sensor and a filling indicator light. The filling indicator light is located on the outer wall of the storage tank, and the water level signal sensor is located on the inner wall of the storage tank to obtain water level information. The water level signal sensor has a fixed water level standard threshold, and the filling indicator light lights up when the water level in the storage tank is lower than the set threshold.

[0010] Furthermore, the float is positioned below the standard water level and two body lengths below the float itself. The metal contacts are located at the electrical connection point, ensuring a circuit path.

[0011] Furthermore, the spiral cultivation tube is made of rigid material, and there are two spiral cultivation tubes. The two spiral cultivation tubes are set vertically and are positioned opposite each other around the center of the return tube. Multiple cultivation holes are opened on the outer side of the upper end of the two spiral cultivation tubes, and the cultivation holes are arranged in a spiral array at equal intervals. A nutrient solution outlet pipe with the same trajectory as the spiral cultivation tube is provided inside the spiral cultivation tube. It is specified that the outer diameter of the outlet pipe is much smaller than the inner diameter of the spiral cultivation tube. A liquid mist conversion nozzle is provided on the lower side of each cultivation hole of the two spiral cultivation tubes. The liquid mist conversion nozzle is the outlet of the outlet pipe.

[0012] Furthermore, the vibrating plate vibrates at a high frequency and with a low amplitude, with a vibration time of 5 seconds.

[0013] Furthermore, the device also includes plant LED lights, which are arranged around the outer wall of the return pipe and are fixedly connected to the return pipe.

[0014] Compared with the prior art, the advantages of this invention are: First, the spiral structure of this design can effectively help vegetables receive sunlight evenly.

[0015] Second, the spiral upper and lower layer structure allows for the planting of more vegetables in a smaller space, solving the problem of large land requirements and a limited variety of vegetables.

[0016] Third, this method is a soilless cultivation method, which can effectively prevent soil continuous cropping obstacles and soil-borne diseases, and save water, fertilizer and labor, and is not limited by natural conditions.

[0017] Fourth, this hydroponics solution uses aerosols to supplement the vegetables with nutrient solution. It also solves the problem of residual droplets in the pipes caused by the nutrient solution being sprayed out as aerosols. The solution is collected again through a spiral structure and a shaking diversion method, and then recycled, thus achieving environmental protection. Attached Figure Description

[0020] Example 1:

[0021] Please see Figure 1-4 A smart and environmentally friendly courtyard cultivation device, comprising a liquid storage tank 1, a return pipe 2, and a spiral cultivation pipe 3.

[0022] The storage tank 1 is frustum-shaped and filled with nutrient solution. A filling indicator light 13 is installed on the outside of the storage tank 1, and a water level sensor 12 is installed inside to obtain water level information. The water level sensor 12 has a fixed water level threshold. The filling indicator light 13 illuminates when the water level in the storage tank 1 is below the set threshold. The specific implementation principle and component structure are conventional and will not be elaborated here. A floating component 11 is installed inside the storage tank 1. The floating component 11 includes a float plate 113, a sliding column 111, and a metal contact plate 112. The floating component 11 is made of a material with a density less than that of the nutrient solution, allowing it to float on the nutrient solution. The sliding column 111 is located above the float plate 113 and is fixedly connected to it. The sliding column 111 penetrates the upper surface of the storage tank 1 and is slidably connected to it. A metal contact plate 112 is located on the outer periphery of the upper end of the sliding column 111.

[0023] The return pump 22 and the return pipe 2 are cylindrical hollow tubes, vertically arranged, penetrating the upper surface of the storage tank 1, with the lower end of the return pipe 2 located at the bottom of the storage tank 1. The return pump 22 is fixedly connected to the outside of the return pipe 2, and a gap exists between the lower end of the return pipe 2 and the bottom of the storage tank 1, allowing the return pipe 2 to completely draw back the nutrient solution from the storage tank 1 through the return pump 22. A filter screen is installed at the bottom of the return pipe 2, which filters out plant residue and other substances carried down by the filtered liquid droplets. Vibrating plates 21 are symmetrically arranged on both sides of the outer periphery of the return pipe 2, and are fixedly connected to the return pipe 2. The return pump 22 is installed on the outer wall of the return pipe 2, and the output end of the vibration motor 24 of the return pump 22 is electrically connected to the receiving end of the vibration plate 21. Note: The vibration motor 24 requires a start signal to drive the vibration plate 21 to vibrate. The plant LED light 23 is installed around the outer wall of the return pipe 2 and is attached to the surface. The plant LED light 23 is fixedly connected to the return pipe 2.

[0024] The spiral cultivation tube 3 includes a tube body, a water storage hopper 31, an electrical wire 32, and a drive control system 33. A nutrient solution outlet pipe with the same trajectory as the spiral cultivation tube 3 is located inside the spiral cultivation tube 3; the outer diameter of the outlet pipe is specified to be much smaller than the inner diameter of the spiral cultivation tube. The upper end of the spiral cultivation tube 3 is connected to the upper end of the return pipe 2, and the lower end of the spiral cultivation tube 3 is connected to the upper end of the storage tank 1. The spiral cultivation tube 3 and the return pipe 2 are fixedly connected. There are two spiral cultivation tubes 3, centered on the circle of the return pipe 2, arranged at opposite angles and vertically. Multiple cultivation holes are opened on the outer side of the upper end of the two spiral cultivation tubes 3. Each cultivation hole is equipped with a liquid mist conversion nozzle on its lower side. The liquid mist conversion nozzle serves as the outlet of the outlet pipe; liquid mist conversion nozzles are conventional technology in this field and will not be described in detail here.

[0025] like Figure 2 As shown: A downwardly recessed water storage hopper 31 is detachably provided at the lower end of the wall of a spiral cultivation tube 3. The water storage hopper 31 is made of waterproof and deformable material. The inner wall of the water storage hopper 31 is water-repellent. A braking component is provided on the outside of the water storage hopper 31. The water storage hopper 31 has a large tilt angle when it is set.

[0026] like Figure 4 A circuit system is provided on the lower side of the water storage tank 31 shown. The circuit is in series, with the positive terminal of the power supply connected to the water storage tank 31 via a wire 32. Both ends of the water storage tank 31 are provided with metal contacts. The metal contact at one end of the water storage tank 31 is connected to the wire 32 at the positive terminal of the power supply, and the metal contact at the other end of the water storage tank 31 is connected to a resistor via a wire 32. The water storage tank 31 is a break in the circuit. When the water storage tank 31 is full of water and forms a horizontal surface, the metal contacts at both ends conduct electricity when they come into contact with water, thus connecting the circuit. When there is no water in the water storage tank 31 or the water level does not reach the height of the metal contacts, the circuit is open. The circuit resistor is connected to the ammeter. The input terminal of the drive control system 33 is electrically connected to the signal output terminal of the ammeter. The ammeter is then connected to the contact point of the floating component 11. The floating component 11 is another open circuit point. A metal contact 112 is provided at the upper end of the floating component 11. When the floating component 11 slides downward and the drop height causes the metal contact 112 to contact the wire 32, the circuit is connected. If the floating component 11 is too low or too high, the metal contact 112 does not contact the wire 32, and the circuit is open. Finally, the contact point of the floating component 11 is connected to the negative terminal of the power supply. The drive control system 33 is located on the upper surface of the liquid storage tank 1. When the drive control system 33 receives a current signal, it can brake the braking component at the outer end of the water storage tank 31, pushing the droplets inside the water storage tank 31 up and flowing down the wall of the spiral cultivation tube 3. At the same time, the drive control system 33 sends a start signal, and the vibration motor 24 receives the start signal to control the vibrating plate 21 to vibrate at small amplitudes and multiple frequencies.

[0027] Working principle: Nutrient solution is stored in the storage tank 1 and flows back into the discharge pipe of the spiral cultivation tube 3 through the return pipe 2. Nutrients are supplied to the plants through the liquid mist conversion port. The liquid droplets remain inside the spiral cultivation tube 3, and due to the slow downward flow of the spiral tube structure, a concentrated portion is collected in the water storage hopper 31. When the water storage hopper 31 is full, the circuits at both ends are connected. One end of the wire 32 is connected to a power source, and the other end is connected to the drive control system 33. A water level signal sensor 12 is installed on the inner wall of the storage tank 1. When the floating component 11 is below the height of the water level signal sensor 12, the metal contact 112 is not at the contact point. When the floating component 11 is below the standard water level and two body lengths below the floating component 11, the metal contact 112 is at the contact point, thus establishing a circuit. All circuits are connected, the drive control system 33 sends a start signal and drives the braking component to brake and push up the water storage hopper 31; the vibration motor 2424 receives the vibration signal and drives the vibrating plate 21 to emit low amplitude, high frequency and short duration vibration, so as to completely drain the water in the spiral cultivation tube 3 through vibration, and achieve the effect of secondary recycling.
