Description

Technical Field

[0001] This utility model relates to the field of seedbed technology, and more specifically to a fully automatic three-dimensional seedbed. Background Technology

[0002] Currently, vertical farms and plant factories are typical representatives of smart agriculture, and corresponding three-dimensional agricultural production devices present a variety of related products, achieving water and fertilizer supply and plant lighting within a three-dimensional space. Water and fertilizer supply generally falls into two categories: one is an integrated water and fertilizer supply pipeline circulation system within a single three-dimensional seedling rack design; the other is an integrated water and fertilizer supply pipeline system for individual seedling racks, with multiple racks combined to form a large-scale system. While the former has lower overall costs, a malfunction in any part of the supply pipeline will prevent the entire seedling rack from receiving normal water and fertilizer. Therefore, the larger the scale, the higher the risk, which explains the scarcity of integrated three-dimensional cultivation products on the market and the relatively small scale of three-dimensional cultivation spaces. Furthermore, product solutions with integrated water and fertilizer supply pipelines for individual seedling racks, combined with multiple racks to form a large-scale system, are relatively more expensive, require more maintenance on larger scales, and thus have higher investment costs. Moreover, there are no control systems on the market that can individually control the cultivation conditions of each layer within a three-dimensional cultivation space. Utility Model Content

[0003] In view of this, and in response to the problems that arise in various three-dimensional cultivation methods for various products, this utility model provides a fully automatic three-dimensional seedbed with simple structure, convenient maintenance, and low investment cost, which can realize the fully automatic cultivation of plant seedlings in three-dimensional space.

[0004] To achieve the above objectives, this utility model provides a fully automatic three-dimensional seedbed, including a seedling rack with several seedling areas arranged in layers on the rack. Each layer of the seedling area is equipped with a seedling mechanism and a sprinkler irrigation mechanism. The seedling mechanism includes a tidal tray with a drainage trough at its bottom. Lights mounted on the seedling rack are installed above each layer of the seedling area. A main sprinkler irrigation pipe and a main drainage pipe are arranged vertically along the seedling rack. The sprinkler irrigation mechanism is connected to the main sprinkler irrigation pipe, and the drainage trough is connected to the main drainage pipe.

[0005] The bottom of the seedling rack is equipped with a water tank and an electrical control cabinet, and the seedling rack is equipped with an operating machine that is electrically connected to the electrical control cabinet.

[0006] Preferably, each layer of the seedling area is provided with a mesh screen, and the tidal tray is placed on the mesh screen.

[0007] Preferably, solenoid valves are installed on the pipelines connecting the main irrigation pipeline to the irrigation mechanisms at each level.

[0008] Preferably, the water tank is equipped with a peristaltic pump.

[0009] Preferably, there are two water tanks, one of which is a foliar fertilizer tank and the other is an irrigation tank.

[0010] Preferably, the sprinkler irrigation mechanism includes a sprinkler pipe and a nozzle, wherein the nozzle is installed at the end of the sprinkler pipe.

[0011] Preferably, the water tank is provided with two buoyancy on / off signal terminals, one high and one low, and the bottom of the main sprinkler pipe is connected to one of the three-way connectors. The other two of the three-way connectors are connected to the diaphragm water pumps respectively through solenoid valves.

[0012] Preferably, the circuit control cabinet is installed in a horizontal waterproof electrical control cabinet. The electrical control cabinet is equipped with a branching device and a relay. The load end of the relay is connected to the water pump, solenoid valve and light in the seedling rack. The signal control end of the relay and the buoyancy signal monitoring end in the water tank are converged through the electrical control cabinet to the operating machine arranged on the seedling rack column.

[0013] Preferably, the operator is an HMI-PLC integrated machine.

[0014] Preferably, the main irrigation pipe and the main drainage pipe are arranged on one side of the seedling rack, and the circuit line that is electrically connected to the circuit control cabinet is placed on the other side of the seedling rack.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of an exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see the appendix Figure 1-3 The present invention discloses a fully automatic three-dimensional seedbed, which includes a seedling rack 1, and several seedling areas 2 are distributed in layers on the seedling rack 1. The seedling areas 2 are used to cultivate plants. Each layer of seedling area 2 is equipped with a seedling mechanism and a sprinkler irrigation mechanism 6.

[0023] The seedling raising mechanism includes a tidal tray 3, the bottom of which is provided with a drainage trough 4. Above each layer of the seedling raising area 2, there is a light 5 installed on the seedling rack 1 (the wiring is waterproofed with hot melt glue to prevent abnormal irrigation from causing a short circuit). The seedling rack 1 is arranged with a main irrigation pipe and a main drainage pipe in a vertical row. The irrigation mechanism 6 is connected to the main irrigation pipe, and the drainage trough 4 is connected to the main drainage pipe.

[0024] In this embodiment, the fully automatic three-dimensional seedbed has four layers, each layer is provided with a support beam 7, a stainless steel mesh 8 is provided on the support beam 7, a tidal tray 3 is placed on each mesh 8, and a plant cultivation light 5 and a uniformly arranged sprinkler mechanism are placed under each mesh 8, wherein the water outlet of the sprinkler mechanism is below the light 5.

[0025] The side of the upright seedling rack 1 is arranged with a vertical arrangement of the main sprinkler irrigation pipe and the main drainage pipe connecting to the tidal tray 3. There are solenoid valves (ball valve type) on the pipeline from the main sprinkler irrigation pipe to each layer of sprinkler mechanism, and the drainage trough 7 of each layer of tidal tray 3 is connected to the main drainage pipe by a drainer.

[0026] The bottom layer of seedling rack 1 consists of two black water tanks, an electrical control cabinet, a tap water inlet valve, water tank 1 (irrigation tank), and water tank 2 (foliar fertilizer tank). Two peristaltic pumps are connected to water tank 2 and the concentrate supply box, respectively. Two buoyancy control signal terminals (high and low) are located within the water tanks. One end of the main sprinkler irrigation pipe is connected to a T-junction at its bottom, and the other two ends are connected to two solenoid valves (ball valve type). Each solenoid valve is connected to a 60W or 100W diaphragm pump (the appropriate pump can be selected based on the specific floor height; for example, a 60W pump can be used at 3 meters). The pump's suction pipe is connected to each of the two water tanks. For ease of placement, the total volume of the two water tanks and the electrical cabinet at the bottom layer does not exceed the volume of the bottom layer itself. The tap water inlet valve is connected via a T-junction to two water pipes located in the two water tanks, each with a solenoid valve pre-installed. The overall water system (main irrigation pipe and main drainage pipe) is located on one side of the seedling rack 1, while the electrical wiring is located on the other side of the seedling rack 1 and is electrically connected to the electrical control cabinet located in the horizontal waterproof electrical control cabinet. The electrical control cabinet contains branching equipment, 24-volt power supply, relays, etc. The relay load terminals are connected to the water pump, solenoid valve, and lights 5 in the entire seedling rack 1. The signal control terminals and the buoyancy signal monitoring terminals in the water tank are connected to the manipulator 9 mounted on the upright of the seedling rack 1 through the electrical control cabinet. The manipulator 9 is an HMI-PLC integrated machine.

[0027] In this example, the operator 9 is equipped with a specific PLC control program and HMI human-machine interface program. The operator can set the real-time clock on the operator 9 and perform fully automatic settings and manual operation of sprinkler irrigation, fertilization and supplemental lighting functions. The sprinkler irrigation function parameters include: selection of different sprinkler layers, setting of sprinkler irrigation time for different sprinkler layers, setting of sprinkler irrigation at intervals of hours or days. After the sprinkler irrigation parameters are set, the operator 9 will call the various hardware facilities such as the solenoid valve in this utility model to perform sprinkler irrigation actions for different selected seedling areas 2 at different times according to the program settings. When the water tank 1 detects no water, the irrigation action will be paused, the solenoid valve at the front of the water tank 1 will be opened, and the irrigation program will continue to be completed after the water tank 1 is full. The operating unit 9 has a separate human-machine interface for fertilization settings. Based on the aforementioned sprinkler irrigation function, it adds setting parameters for the volume of two concentrated fertilizer solutions added to water tank 2. After the automatic fertilization function is set on the operating unit 9, it calls the diaphragm pump on water tank 2 and the three-way solenoid valve that switches the main pipeline according to the set time. According to the program settings, it sequentially performs foliar fertilizer application operations at different times for different selected seedling areas 2. When water tank 2 detects no fertilizer solution, the operating unit 9 will, according to the program settings, activate the two peristaltic pumps and the front-end water injection solenoid valve to add different concentrated fertilizer solutions and water to water tank 2 respectively. After mixing evenly, it continues to complete the fertilization operation. The fully automatic supplemental lighting function on the operating unit 9, based on the set real-time clock and on / off clock, allows different selected seedling areas 2 to perform two supplemental lighting on and off operations. The interval between the on and off of lights in different layers can also be set on the operating unit 9 (to prevent electrical accidents caused by the simultaneous on of high-power supplemental lights in different layers). In this example, irrigation, fertilization, and supplemental lighting are all individual functions, which can be operated simultaneously and alternately after being set on the operator 9.

[0028] It should be noted that the water systems (sprinkler irrigation main pipes and drainage main pipes) between multiple fully automatic three-dimensional seedbeds can be connected through pipelines, and the working status of all water systems can be controlled through a single circuit control cabinet.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.
