However, greenhouse seedling production requires a large amount of energy to maintain the indoor temperature, but the large space inside the greenhouse results in low overall heating efficiency. Current seedbed seedling production has significant shortcomings in terms of heating, heat preservation, and watering, often leading to uneven germination rates and low marketable yields.

[0056] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0057] This utility model embodiment provides a smart seedbed with automatic heating, heat preservation and water replenishment functions. Its structure and connection relationship are described in detail below with reference to the accompanying drawings.

[0058] refer to Figures 1 to 3 This utility model embodiment provides a smart seedbed with automatic heating, heat preservation, and water replenishment functions, including a seedbed body 1, an electric heating wire system, and several heat preservation layers 21.

[0059] The seedbed body 1 includes a base plate 10 and side plates 11 arranged around the base plate 10. The top end of the seedbed body 1 is equipped with a push-pull panel 12.

[0060] The electric heating wire heating system includes a heating wire mesh 2, which is disposed in the bottom plate 10 and / or side plate 11 of the seedbed body 1;

[0061] Several insulation layers 21 are respectively laid inside the side panels 11 around the seedbed body 1 and inside the sliding panel 12, and the insulation layer 21 is provided with insulation material.

[0062] When the heating wire mesh 2 is energized, it heats the interior of the seedbed 1, while the insulation layer 21 above and around the seedlings reduces heat loss. This embodiment of the invention discloses a smart seedbed with automatic heating, insulation, and water replenishment functions, which not only achieves heating but also ensures insulation, solving the significant shortcomings in insulation and heating aspects of seedbed cultivation.

[0063] Specifically, the seedbed body 1 includes a base plate 10, four side plates 11, and a push-pull panel 12. The base plate 10 is a rectangular plate, the four side plates 11 are respectively arranged on the four sides of the base plate 10, and the push-pull panel 12 is arranged at the top end of the seedbed body 1.

[0064] In order to ensure that the heating system provides uniform and continuous heat to maintain a suitable temperature inside the seedbed for seedling growth, one specific implementation is that the bottom plate 10 of the seedbed body 1 is made of polystyrene board.

[0065] The heated wire mesh 2 is arranged inside the bottom plate 10 of the seedbed body 1 to generate heat;

[0066] The bottom surface of the base plate 10 of the seedbed body 1 below the heated wire mesh 2 is covered with a heat-reflective film 20 to reflect heat.

[0067] To effectively retain heat within the seedbed and reduce heat loss, the insulation material within the insulation layer 21 is polyurethane foam, mineral wool, or glass wool. These insulation materials effectively isolate external temperature fluctuations, ensuring a stable internal temperature for the seedbed.

[0068] To maintain the temperature within the seedbed within a preset range and ensure that seedlings at different growth stages can grow in the most suitable temperature environment, this intelligent seedbed with automatic heating, heat preservation, and water replenishment functions also includes a temperature control system. The temperature control system includes a temperature sensor, a first control unit, and a display screen 3.

[0069] The heated wire mesh 2 is equipped with an energizer switch, and the temperature sensor, the energizer switch of the heated wire mesh 2, and the display screen 3 are respectively connected to the first control unit via wires.

[0070] The temperature sensor is installed inside the seedbed body 1 to monitor the temperature inside the seedbed in real time.

[0071] The first control unit is used to transmit the temperature value collected by the temperature sensor to the display screen 3, and to control the power switch of the heating wire mesh 2 to be turned on or off.

[0072] The display screen 3 is disposed on the surface of the side plate 11 of the seedbed body 1 and is used to display the temperature value collected by the temperature sensor.

[0073] To ensure that the seedlings receive adequate water, operators need to precisely adjust the irrigation amount based on the guidance data. Therefore, the intelligent seedbed with automatic heating, heat preservation and water replenishment functions also includes an automatic water replenishment system, which includes a water loss measuring device and an automatic watering device.

[0074] In order to accurately measure the water loss of the seedbed 1, the water loss measuring device includes at least one seedling tray 41 and at least one gravity sensor 42, wherein the seedling tray 41 is mounted on the bottom plate 10 or side plate 11 of the seedbed 1 via the gravity sensor 42.

[0075] In one specific implementation, the seedling tray 41 is disposed within the seedbed body 1 with an annular space between them, and the gravity sensors 42 are evenly spaced within the annular space between the seedling tray 41 and the seedbed body 1, such as... Figure 2 As shown, each gravity sensor 42 is equipped with an upper fixing member 421 and a lower fixing member 422 at both ends. The upper fixing member 421 of the gravity sensor 42 is fixed to the side plate 11 of the seedbed body 1, and the lower fixing member 422 of the gravity sensor 42 is fixed to the side wall of the seedling tray 41, as shown. Figure 4 As shown.

[0076] The gravity sensor 42 can collect the weight change of the seedling tray 41 in real time to reflect the change in water content, and then guide whether watering is needed based on the change in water content in the seedling tray 41.

[0077] In one specific implementation, the seedling tray 41 is installed on the bottom plate 10 or side plate 11 of the seedbed body 1 using a single-point pressure or pull, three-point pressure or pull, or four-point pressure or pull method via a gravity sensor 42.

[0078] In one specific implementation, when there is only one gravity sensor 42, the single gravity sensor 42 is fixed on the base plate 10 of the seedbed body 1, and the seedling tray 41 is directly set on the single gravity sensor 42 using a single-point pressure method.

[0079] One specific implementation is that when the number of gravity sensors 42 is four, such as... Figure 2 As shown, four gravity sensors 42 are evenly spaced at the four corners of the rectangular annular space between the seedling tray 41 and the seedbed body 1, and the two ends of each gravity sensor 42 are fixedly connected to the seedling tray 41 and the seedbed body 1 respectively.

[0080] Among them, the bottom of the side plate 11 of the seedbed body 1 is respectively equipped with a crossbeam 110, the upper fixing part 421 of the four gravity sensors 42 is respectively suspended on the crossbeam 110 of the four side plate 11 of the seedbed body 1, and the lower fixing part 422 of the four gravity sensors 42 is respectively fixed to the outer wall of the seedling tray 41.

[0081] Specifically, the automatic watering device includes a second control unit 50, a water tank 51, a water pump 52, several nozzles 53, several flow meters 54, and several solenoid valves 55.

[0082] The seedbed 1 is equipped with a bed frame 13, and the water tank 51 is located below the bed frame 13;

[0083] The water pump 52 is installed inside the water tank 51;

[0084] Several nozzles 53 are arranged inside the seedbed body 1 and are evenly spaced on the seedling tray 41;

[0085] The outlet of the water pump 52 is connected to several nozzles 53 through a pipe, and a flow meter 54 and a solenoid valve 55 are respectively installed on the pipe connecting the water pump 52 and each nozzle 53.

[0086] Each of the gravity sensor 42, the water pump 52, the plurality of flow meters 54, and the plurality of solenoid valves 55 is respectively connected to the second control unit 50 via wires, such as Figure 5 As shown.

[0087] When the gravity sensor 42 transmits the real-time weight change of the seedling tray 41 to the second control unit 50 to reflect the change in water content, the second control unit 50 determines whether watering is needed based on the change in water content in the seedling tray 41. If watering is needed, the second control unit 50 controls the water pump 52 to start and opens the solenoid valve 55 of the corresponding nozzle 53 to deliver water from the water tank 51 to the corresponding nozzle 53 until the water volume monitored by the flow meter 54 corresponds to the weight change of the seedling tray 41.

[0088] The water loss measuring device and the automatic watering device together constitute an automatic water replenishment system. The water loss measuring device is used to measure the water loss of the seedbed 1, and the automatic watering device is used to automatically water the seedbed 1.

[0089] To display the water replenishment status of the automatic water replenishment system, the display screen 3 is connected to the second control unit 50. In addition to displaying the current temperature and heating temperature, the display screen 3 can also display the water replenishment status. When it is in the water replenishment status, the green light is on.

[0090] To prevent seedlings from becoming leggy due to lack of light, it is sometimes necessary to provide them with sufficient light, especially when light conditions are poor, such as on cloudy or rainy days, during short winter days, or in environments with insufficient indoor light. Therefore, this intelligent seedbed with automatic heating, insulation, and watering functions also includes a supplemental lighting device.

[0091] The supplemental lighting device includes two tracks and several supplemental lights 61. The two tracks are respectively set on the top surface of the side plates 11 on both sides of the seedbed body 1, and the push-pull panel 12 is set on the tracks on both sides.

[0092] Several of the aforementioned supplementary lights 61 are evenly distributed on the bottom surface of the push-pull panel 12.

[0093] The insulation layer 21 of the sliding panel 12 helps to improve the insulation effect of the seedbed to meet the growth needs of different plants. The supplementary light 61 on the bottom surface of the sliding panel 12 can cover the entire seedbed with light and can be used for supplementary lighting of the seedbed.

[0094] As one specific implementation, a handle 14 is provided on the push-pull panel 12 for the convenience of the operator. When the operator holds the handle 14 and pushes or pulls, the push-pull panel 12 opens and closes respectively.

[0095] The sliding panel 12 is designed to maximize space utilization and allows for quick opening and closing, facilitating the management of the seedbed. To ensure the secure installation of the insulation material, fixing devices are also provided on both sides of the sliding panel 12.

[0096] To improve the automation level of the push-pull panel 12 in opening and closing, thereby reducing operational workload, the push-pull panel 12 is equipped with an automatic operation system, which includes a third control unit, a drive mechanism, and a sensing mechanism.

[0097] The drive mechanism and the sensing mechanism are configured with the push-pull panel 12, and the drive mechanism and the sensing mechanism are respectively connected to the third control unit;

[0098] The drive mechanism is used to drive the push-pull panel 12 to open and close;

[0099] The sensing mechanism is used to sense when the push-pull panel 12 needs to be opened or closed and to send the sensing information to the third control unit;

[0100] The third control unit is used to control the drive mechanism according to the sensing information to realize the opening or closing of the push-pull panel 12.

[0101] Specifically, the driving mechanism is a linear motor, the push-pull panel 12 is equipped with a push-pull rod, and the output shaft of the linear motor is fixedly connected to the push rod of the push-pull panel 12;

[0102] The sensing mechanism is an infrared sensor, and the infrared rays emitted by the infrared sensor are directed at the top of the push-pull panel 12.

[0103] The infrared sensor and the linear motor are respectively connected to the third control unit via wires.

[0104] When the infrared sensor detects that an operator's hand has passed over the push-pull panel 12, the infrared sensor sends the sensing information to the third control unit. The third control unit controls the linear motor to start, and the linear motor pushes or pulls the push-pull panel 12 through the push-pull rod, thereby realizing the automatic opening or closing of the push-pull panel 12.

[0105] Optionally, the first control unit, the second control unit, and the third control unit can be three different controllers, or they can be the same controller.

[0106] Since the seedling growth cycle is divided into three modes—germination mode, growth mode, and hardening mode—the third control unit in the temperature control system can be set according to each of these three modes. The temperature can be freely set according to different seedling crops in each mode, ensuring that seedlings at each growth stage can grow under the most suitable temperature conditions.

[0107] To address the specific growth needs of solanaceous and cucurbit seedlings, the temperature control system has been configured with detailed temperature parameters. For example, for solanaceous plants: in germination mode, the nighttime substrate temperature is maintained at 25-30℃; in growth mode, the nighttime air temperature is maintained at 18-22℃; and in hardening-off mode, the nighttime air temperature is maintained at 12-15℃. For cucurbits: in germination mode, the nighttime substrate temperature is maintained at 28-30℃; in growth mode, the nighttime air temperature is maintained at 15-18℃; and in hardening-off mode, the nighttime air temperature is maintained at 14-16℃.

[0108] In summary, the intelligent seedbed with automatic heating, heat preservation, and water replenishment functions disclosed in this utility model embodiment utilizes the heating wire mesh 2 of the electric heating system to generate heat, achieving heating, and the heat preservation layer 21 to reduce heat loss and ensure heat preservation effect. Together, they achieve efficient heating and heat preservation. The temperature control system ensures that seedlings at different growth stages can grow in the most suitable temperature environment. The water loss measuring device of the automatic water replenishment system measures the water loss of the seedbed body 1, and the automatic watering device automatically waters the seedbed body 1, achieving automatic water replenishment. The supplementary lighting device uses supplementary lighting lamps 61 to provide supplementary lighting for the seedlings. The automatic operation system of the push-pull panel ensures the automatic operation of the push-pull panel 12.

[0109] The intelligent seedbed with automatic heating, heat preservation, and water replenishment functions disclosed in this embodiment of the utility model achieves intelligent control and convenient management of the seedbed through the heating of the wire mesh 2, the heat preservation of the insulation layer 21, the water replenishment of the automatic water replenishment system, the supplementary lighting 61, and the automatic operation of the push-pull panel automatic operation system. It can meet the needs of seed germination in the substrate, prevention of excessive growth, and seedling hardening in the seedling trays, providing a higher quality and more efficient seedling solution for agricultural planting.
