Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural seedling raising, and specifically relates to an efficient agricultural seedling raising device based on the Internet of Things. Background Technique

[0002] Seedling raising is an important link in agricultural production, which refers to cultivating plant seedlings under suitable conditions for subsequent transplantation into fields or other growth environments. During the seedling raising process, in addition to the selection of seeds and soil, environmental parameters such as seedling raising temperature and humidity will have a greater impact on the seedling raising effect.

[0003] If manual detection and regulation of the environmental parameters of seedling raising are adopted, it will consume a large amount of labor costs. Therefore, the existing seedling raising environment monitoring is mostly based on the Internet of Things technology. The Internet of Things technology can collect the environmental parameters during the seedling raising process in real time through sensing devices, realize remote monitoring and management, and can effectively improve the efficiency and quality of agricultural production.

[0004] Although the seedling raising device based on the Internet of Things effectively improves the efficiency and quality of agricultural production, most of the existing seedling raising devices based on the Internet of Things are simple plastic tray seedling raising devices. These devices have poor permeability during the seedling raising process. When there is too much water, it is easy to cause the bed soil to be blocked, affecting the emergence of all seedlings, and thus reducing the efficiency of seedling raising.

[0005] Therefore, it is necessary to propose a seedling raising device that conducts remote monitoring and management of seedling raising based on the Internet of Things technology and can improve the permeability during the seedling raising process. Content of the Utility Model

[0006] In order to solve the above problems, the purpose of the utility model is to propose an efficient agricultural seedling raising device based on the Internet of Things, which discharges the excess water during the seedling raising process through the water outlet holes and water outlet grooves, reducing the possibility of the bed soil being blocked; by connecting the device to the Internet of Things, real-time monitoring of the plant state and intelligent adjustment of the plant environment are realized.

[0007] In order to achieve the above purpose, the technical solution of the utility model is as follows: An efficient agricultural seedling raising device based on the Internet of Things, including a seedling raising cabinet with a hollow interior. A controller is fixedly connected to the side wall of the seedling raising cabinet. An Internet of Things module for transmitting and receiving signals is provided inside the controller. The input end of the Internet of Things module is electrically connected to the output end of the controller, and the output end of the Internet of Things module is electrically connected to the input end of the controller. A plurality of partition plates are fixedly connected inside the seedling raising cabinet, and the partition plates divide the inner side wall of the seedling raising cabinet into a plurality of seedling raising cavities; a heat storage layer is fixedly connected to the inner wall of each seedling raising cavity, a water and fertilizer mixing component for mixing water and fertilizer is provided at the top of each seedling raising cavity, a collection component for collecting and transmitting the plant state to the controller is symmetrically provided on the inner side wall of each seedling raising cavity, and a seedling raising component for cultivating plants is provided at the bottom of each seedling raising cavity.

[0008] The following principles and beneficial effects are achieved by adopting the above solution:

[0009] Basic principle: The controller controls the acquisition component in the seedling-raising cavity to collect images of the state of the plants in the seedling-raising component, and sends the collected image information to the controller. After receiving the plant image information, the controller sends a search signal to the Internet of Things through the Internet of Things module. The Internet of Things conducts a search for the relevant plant state and organizes the retrieved materials into feedback information. After the organization is completed, the Internet of Things sends the feedback information to the Internet of Things module, and the Internet of Things module sends the feedback information to the controller. At this time, the controller analyzes the plant state based on the feedback information and the plant image information, and obtains an analysis result. When the plant lacks water, the controller controls the water and fertilizer mixing component to release water and irrigate the plant; when the plant lacks nutrients, the controller controls the water and fertilizer mixing component to fertilize the plant; when the plant lacks both nutrients and water, the controller controls the water and fertilizer mixing component to release and mix water and fertilizer at the same time. At this time, the controller controls the water and fertilizer mixing component to pour the water and fertilizer mixture onto the plant. When the temperature in the seedling-raising cabinet rises, the heat storage layer will accumulate part of the heat in the heat storage layer.

[0010] Beneficial effects: 1. By connecting the device to the Internet of Things, the present utility model realizes the real-time monitoring of the plant state and the intelligent adjustment of the plant environment, improves the efficiency of seedling raising, and the Internet of Things technology can ensure the stability of the seedling-raising environment, reducing the abnormal growth of crops caused by human factors or environmental mutations, thus helping to improve the quality and consistency of seedling raising.

[0011] 2. In the present utility model, the design of the heat storage layer enables the heat energy to be accumulated in the heat storage layer while the temperature in the seedling-raising cabinet rises, reducing the loss of energy. And when the temperature in the seedling-raising cabinet drops, the heat storage layer can release heat to balance the internal temperature of the seedling-raising cabinet.

[0012] 3. In the present utility model, the design of several seedling-raising cavities realizes the batch selection of plants, improving the production efficiency while reducing the excessive consumption of resources caused by multiple seedling raisings.

[0013] Furthermore, the water-fertilizer mixing components each include a partition board and a mixing isolation board fixedly connected to the inner side wall of the seedling-raising cavity from top to bottom in sequence. Both the partition board and the mixing isolation board divide the interior of the seedling-raising cavity into a liquid storage cavity, a mixing cavity, and an irrigation cavity from top to bottom in sequence. At the top of the partition board, a water-fertilizer separation board is fixedly connected, and the water-fertilizer separation board divides the liquid storage cavity into a water storage cavity and a fertilizer storage cavity; at the bottom of the partition board, a number of electric sliding tables are fixedly connected, and at the bottom of the partition board, a first through hole and a second through hole are respectively opened. The first through hole and the second through hole are respectively located at the bottom of the water storage cavity and the bottom of the fertilizer storage cavity. Below the partition board, a first sliding plate and a second sliding plate corresponding to the first through hole and the second through hole are respectively provided. At the top of the first sliding plate and the second sliding plate, a slider is fixedly connected, and the slider is slidably matched with the electric sliding table. The input ends of the electric sliding tables are signal-connected to the output end of the controller; at the bottom of the mixing isolation board, a number of spray heads are fixedly connected, and the spray heads are communicated with the mixing cavity. The input ends of the spray heads are signal-connected to the output end of the controller.

[0014] Beneficial effects: The design of separating the water storage cavity and the fertilizer storage cavity ensures that water and fertilizer remain independent before mixing, reducing the possibility of chemical reactions or precipitation caused by premature mixing of water and fertilizer, thus ensuring the accuracy of the water-fertilizer ratio. At the same time, the design of the mixing cavity enables water and fertilizer to be fully mixed after entering, forming a uniform water-fertilizer mixed solution, and being evenly sprayed into the irrigation cavity through the spray heads, providing precise and efficient irrigation services for the plants.

[0015] Furthermore, at the bottom of the mixing isolation board, a number of LED lights are fixedly connected, and the input ends of the LED lights are signal-connected to the output end of the controller.

[0016] Beneficial effects: The controller realizes the adjustment of the light intensity of the plants by controlling the LED lights, thereby better simulating the real light environment.

[0017] Furthermore, the acquisition component includes a number of infrared cameras symmetrically and fixedly connected to the inner side wall of the irrigation cavity. At the top of the infrared cameras, a temperature and humidity sensor is fixedly connected. The output ends of the temperature and humidity sensors are connected to the input end of the controller, and the output ends of the infrared cameras are connected to the input end of the controller.

[0018] Beneficial effects: The infrared cameras first collect the image information of the plants and send the image information to the controller. At this time, the controller sends search information to the Internet of Things through the Internet of Things module. After the Internet of Things completes the search, it sorts the searched materials into feedback information and sends it back to the Internet of Things module, and the Internet of Things module sends the feedback information to the controller. After receiving the feedback information, the controller analyzes the state of the plants according to the image information of the plants, obtains the analysis result, and finally controls the device to adjust the growth conditions of the plants.

[0019] Furthermore, the seedling-raising component includes a seedling-raising frame fixedly connected to the lower part of the inner side wall of the irrigation cavity. The seedling-raising frames are all filled with soil, and a number of water outlet holes are opened at the bottom of each seedling-raising frame. Water outlet grooves are opened below each seedling-raising frame, and the water outlet grooves all extend outside the seedling-raising cabinet.

[0020] Beneficial effects: The design of the water outlet holes and the water outlet grooves enables excess water in the soil to flow out through the water outlet holes and the water outlet grooves during the seedling-raising process, thereby reducing the possibility of the plants being affected by excess water and improving the survival rate of the plants.

[0021] Furthermore, the capacities of the water storage cavity and the fertilizer storage cavity are both 10 - 20 liters.

[0022] Beneficial effects: The design that the capacities of the water storage cavity and the fertilizer storage cavity are both not less than 10 liters ensures the sufficient supply of water and nutrients for the plants. In dry seasons or seasons with rapid water evaporation, the larger water storage capacity helps to maintain the humidity of the soil or medium, reducing the risk of seedling growth retardation or death due to water shortage. At the same time, the larger fertilizer storage capacity makes the fertilization process of the equipment more flexible and accurate.

[0023] Furthermore, the fertilizer selected is liquid compound fertilizer.

[0024] Beneficial effects: Compound fertilizers have the characteristics of stable nutrient content, long-lasting fertilizer efficiency, and convenient use, and can provide various required nutrients for plants at the same time.

[0025] Furthermore, ventilation fans are symmetrically and fixedly connected to the side walls of the irrigation cavity, and the input ends of the ventilation fans are all in signal connection with the output end of the controller.

[0026] Beneficial effects: The controller can control the start and stop of the ventilation fans, thereby ventilating the inside of the irrigation cavity, promoting gas exchange inside the irrigation cavity, and reducing the occurrence of plant diseases.

[0027] Furthermore, a heat exchanger is fixedly connected to one side wall in the length direction of the seedling-raising cabinet, and the input end of the heat exchanger is in signal connection with the output end of the controller.

[0028] Beneficial effects: When the temperature inside the seedling-raising cabinet is low, the controller controls the heat exchanger to start, exchanges the heat from the heat storage layer, and heats the internal temperature of the seedling-raising cabinet.

[0029] Furthermore, the heat storage layer is composed of a number of zeolites filled.

[0030] Beneficial effects: Zeolite, as a heat storage material, has the characteristics of large energy storage density and high efficiency. During the process of adsorbing and releasing water molecules, zeolite can store and release a large amount of heat energy, and zeolite has the characteristics of high stability and long service life, and can still maintain a good heat storage effect after multiple cycles of use.

Specific embodiments

[0036] The following is a further detailed description through specific embodiments:

[0037] Embodiment 1:

[0038] Basically as shown in the attached Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 Shown:

[0039] An agricultural high-efficiency seedling-raising device based on the Internet of Things, including a seedling-raising cabinet 1 with a hollow interior. The side wall of the seedling-raising cabinet 1 is bolted and fixed with a controller 15. The model of the controller 15 is preferably JY-0099336. An Internet of Things module for transmitting and receiving signals is provided inside the controller 15. The input end of the Internet of Things module is electrically connected to the output end of the controller, and the output end of the Internet of Things module is electrically connected to the input end of the controller; A plurality of partition plates are welded on the inner side wall of the seedling-raising cabinet 1, and the inner part of the seedling-raising cabinet 1 is divided into a plurality of seedling-raising cavities by the plurality of partition plates; A heat storage layer is adhered to the inner wall of each seedling-raising cavity, and the heat storage layer is composed of a plurality of zeolites filled.

[0040] At the top of each seedling-raising cavity, a water and fertilizer mixing component for mixing water and fertilizer is provided. Each water and fertilizer mixing component includes a barrier plate 5 and a mixing isolation plate 6 welded to the inner side wall of the seedling-raising cavity from top to bottom in sequence. A plurality of LED lamps 7 are bolted and fixed to the bottom of the mixing isolation plate 6, and the input ends of the LED lamps 7 are signal-connected to the output end of the controller 15.

[0041] The barrier plate 5 and the mixing isolation plate 6 both divide the interior of the seedling cultivation cavity into a liquid storage cavity, a mixing cavity, and an irrigation cavity from top to bottom in sequence. The top of the barrier plate 5 is welded with a water-fertilizer separation plate 3, and the water-fertilizer separation plate 3 divides the liquid storage cavity into a water storage cavity and a fertilizer storage cavity; several electric sliders are bolted and fixed to the bottom of the barrier plate 5, and a first through hole and a second through hole are respectively formed at the bottom of the barrier plate 5. The first through hole and the second through hole are respectively located at the bottom of the water storage cavity and the bottom of the fertilizer storage cavity. A first sliding plate 4 and a second sliding plate 2 corresponding to the first through hole and the second through hole are respectively arranged below the barrier plate 5. Sliders are welded to the tops of the first sliding plate 4 and the second sliding plate 2, and the sliders are slidably matched with the electric sliders. The model of the electric slider is preferably ZDM120, and the input ends of the electric sliders are signal-connected to the output end of the controller 15.

[0042] Several nozzles 8 are bolted and fixed to the bottom of the mixing isolation plate 6. The model of the nozzle 8 is preferably ZSTKX-15. The nozzles 8 are all communicated with the mixing cavity, and the input ends of the nozzles 8 are signal-connected to the output end of the controller 15.

[0043] Collection components for collecting and sending the plant state to the controller are symmetrically arranged on the inner side walls of the irrigation cavity. The collection components include several infrared cameras 13 symmetrically bolted and fixed to the inner side walls of the irrigation cavity. The model of the infrared camera 13 is preferably 4MM B12HV3 POE. Temperature and humidity sensors 12 are bolted and fixed to the tops of the infrared cameras 13. The model of the temperature and humidity sensor 12 is preferably LFH10A. The output ends of the temperature and humidity sensors 12 are signal-connected to the input end of the controller 15, and the output ends of the infrared cameras 13 are signal-connected to the input end of the controller 15.

[0044] Seedling cultivation components for cultivating plants are arranged at the bottom of the irrigation cavity. The seedling cultivation components include seedling cultivation frames 9 welded to the lower parts of the inner side walls of the irrigation cavity. The seedling cultivation frames 9 are filled with soil, and several water outlet holes are formed at the bottoms of the seedling cultivation frames 9. Water outlet grooves 10 are formed below the seedling cultivation frames 9, and the water outlet grooves 10 all extend outside the seedling cultivation cabinet 1.

[0045] The specific implementation process is as follows: The staff operates the controller 15 to start the equipment. At this time, the infrared camera 13 collects the plant state in real time to obtain the image information of the plant and sends the image information to the controller 15. After receiving the image information of the plant, the controller 15 first sends a search signal to the Internet of Things through the Internet of Things module. The Internet of Things searches for various state information of the plant and sorts the searched data into feedback information and sends it back to the Internet of Things module. The Internet of Things module sends the feedback information to the controller 15. After receiving the feedback information, the controller 15 analyzes the state of the plant according to the feedback information and the image information of the plant.

[0046] When the leaves of the plant wilt and the leaf color turns dark green or dark brown, the controller 15 determines that the plant is in a water-deficient state. At this time, the controller 15 controls the electric slide table to start. At this time, the electric slide table drives the slider on the first slide plate 4 to move, and the slider on the first slide plate 4 drives the first slide plate 4 to move, releasing the water in the water storage cavity to irrigate the plant. When spots appear on the leaves of the plant, the leaf color turns yellowish or shows chlorosis, the controller 15 determines that the plant is currently in a state of lacking fertilizer. At this time, the controller 15 controls the electric slide table to start. At this time, the electric slide table drives the slider on the second slide plate 2 to move, and the slider on the second slide plate 2 drives the second slide plate 2 to move, releasing the compound liquid fertilizer in the fertilizer storage cavity to fertilize the plant. The controller 15 will adjust the release of water and compound liquid fertilizer according to the plant state. For example, when the plant shows characteristics of both water deficiency and fertilizer deficiency at the same time, the controller 15 will control the electric slide table to start, so that the electric slide table drives the slider on the first slide plate 4 and the slider on the second slide plate 2 to move respectively. At this time, the slider on the first slide plate 4 drives the first slide plate 4 to move, releasing water, and the slider on the second slide plate 2 drives the second slide plate 2 to move, releasing the compound liquid fertilizer, allowing the water and compound liquid fertilizer to be mixed in the mixing cavity. After the mixing is completed, the staff operates the controller 15 to open the nozzle 8, so that the mixed solution of water and compound liquid fertilizer is sprayed on the plant through the nozzle 8.

[0047] The controller 15 can adjust the light intensity of the LED lamp 7 to ensure that the light conditions of the plant are met during the seedling raising process.

[0048] When the plant releases carbon dioxide, the temperature inside the seedling raising cabinet 1 will rise according to the increase in the concentration of carbon dioxide. At this time, the zeolite can absorb heat as a heat storage material to control the temperature inside the seedling raising cabinet 1.

[0049] When there is too much water inside the irrigation cavity, the excess water will flow out through the water outlet holes and the water outlet groove 10, reducing the situation where the growth of the plant is affected due to excessive water.

[0050] Embodiment 2:

[0051] Basically as shown in the appendix Figure 2 shown:

[0052] The difference from the above embodiment is that the capacities of the water storage cavity and the fertilizer storage cavity are both 10 - 20 liters. In this embodiment, a capacity of 20 liters is selected, and the fertilizer selected is liquid compound fertilizer.

[0053] The specific implementation process is as follows: When the plant needs to be fertilized, the controller 15 analyzes the specific needs and growth stage of the crop based on the feedback information, and precisely controls the mixing ratio of water and fertilizer to ensure that the crop obtains an appropriate amount of nutrients. The design of selecting the fertilizer as liquid mixed fertilizer reduces the possibility of the fertilizer clogging the second through hole and increases the overall stability of the equipment.

[0054] Example 3:

[0055] Basically as shown in the appended Figure 2 and Figure 4 figure:

[0056] The difference from the above embodiment is that ventilation fans 11 are symmetrically fixedly connected to the side walls of the irrigation chamber by bolts. The model of the ventilation fan 11 is preferably the SF2-2-120W / 220V duct type, and the input ends of the ventilation fans 11 are all signal-connected to the output end of the controller 15.

[0057] The specific implementation process is as follows: When the temperature in the seedling raising cabinet 1 sensed by the temperature and humidity sensor 12 is higher than 30 °C, the controller 15 controls the ventilation fan 11 to start to cool the inside of the seedling raising cabinet 1.

[0058] Example 4:

[0059] Basically as shown in the appended Figure 1 and Figure 4 figure:

[0060] The difference from the above embodiment is that a heat exchanger 14 is fixedly connected to one side wall in the length direction of the seedling raising cabinet 1 by bolts. The model of the heat exchanger 14 is preferably SRPDX18, and the input end of the heat exchanger 14 is signal-connected to the output end of the controller 15.

[0061] The specific implementation process is as follows: When the temperature in the seedling raising cabinet 1 sensed by the temperature and humidity sensor 12 is lower than 15 °C, the controller 15 controls the heat exchanger 14 to start. Since the heat storage layer stores the accumulated heat in the heat exchanger 14, when the air in the seedling raising chamber passes through the heat exchanger 14, it will be heated by the heat exchanger 14 and returned to the seedling raising chamber to heat the inside of the seedling raising cabinet 1.
