[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See also Figures 1-7 A factory-based fully automatic seedling raising control system is installed in a seedling raising equipment 1. The seedling raising equipment 1 includes a mounting hood 11 and a light-transmitting protective plate installed on the front side of the mounting hood 11. The mounting hood 11 is evenly equipped with multiple layers of seedling raising trays.

[0037] It includes a light control component, a humidity control component, a temperature control component installed in the installation cover 11 and a ventilation component installed on the back side of the seedling raising equipment 1.

[0038] The lighting control component includes a fluorescent lamp 21, a tray bracket 22, a lifting bracket 23, and a supporting link 24. The tray bracket 22 includes multiple layers rotatably installed in the mounting machine cover 11. The seedling tray is assembled on the tray bracket 22. Fluorescent lamps 21 are installed on the top of each layer of the tray bracket 22. The lifting bracket 23 is slidably installed on the inner side of the mounting machine cover 11. The supporting link 24 includes multiple groups, and the two ends of the supporting link 24 are respectively hinged with the tray bracket 22 and the lifting bracket 23.

[0039] The humidity control component includes a plurality of spray pipes 31 fixed in the mounting hood 11 and arranged above each layer of tray brackets 22; the temperature control component includes a plurality of air distribution plates 41 fixed in the mounting hood 11 and arranged below each layer of tray brackets 22; and the ventilation component is assembled on the back side of the mounting hood 11.

[0040] With the help of the seedling raising control system, the light intensity, temperature, humidity and ventilation status of the seedlings on each layer of the seedling raising tray loaded in the seedling raising equipment 1 can be adjusted to ensure that the seedlings can grow normally.

[0041] For the seedling raising equipment 1, the setting of the machine cover 11 can ensure that the seedlings planted in the seedling raising tray grow stably in an independent environment suitable for their growth characteristics, and the light-transmitting arc plate installed on the front side can ensure that the seedlings absorb sufficient sunlight.

[0042] As for the light control component, its tray bracket 22 can ensure that the seedling tray is stably loaded thereon. By controlling the vertical lifting posture of the lifting bracket 23, the tray brackets 22 of each layer can be driven to deflect synchronously through the supporting connecting rod 24, so that the seedlings planted in the seedling tray can adapt to the irradiation angle of sunlight to ensure that the seedlings can absorb a sufficient amount of sunlight.

[0043] Assembly openings 221 are evenly arranged on the tray support 22 , which can ensure that the seedling raising tray can be stably installed in the assembly openings 221 .

[0044] On rainy days or other occasions when sunlight is insufficient, the fluorescent lamp 21 can be controlled to start working to provide additional light for the seedlings planted in the seedling raising tray below.

[0045] For the humidity control component, the water can be evenly sprayed into each seedling tray through the spray pipe 31 for the seedlings to absorb. For the temperature control component, the air distribution plate 41 can spray the set air heated to the set temperature upward into the installation cover 11 to evenly increase the ambient temperature of each part of the installation cover 11, ensuring that the seedlings are always grown at the optimal temperature.

[0046] When the temperature and humidity of the internal environment of the installation hood 11 need to be lowered and the seedlings need to be ventilated, the ventilation component is controlled to achieve forced circulation of the temperature inside and outside the installation hood 11 to reduce the internal environment temperature and humidity and replace the internal air.

[0047] The seedling raising control system provided in the present application is used in conjunction with various types of sensors installed on each layer of the tray bracket 22, including temperature sensors, humidity sensors, light sensors, and carbon dioxide concentration sensors, to detect the ambient temperature, humidity, light intensity, and carbon dioxide concentration inside the installation hood 11, and transmit the output to the processor. The processing seat makes operating instructions for the light control component, humidity control component, temperature control component, and ventilation component based on the various data, so as to improve the internal environmental state of the installation hood 11 when each component is running.

[0048] In order to facilitate the removal of the seedling raising tray in the installation machine cover 11 and to facilitate the control of the overall movement of the seedling raising equipment 1, the following technical solution is provided.

Both the upper protective plate 121 and the lower protective plate 122 are made of light-transmitting plastic plates, and a metal frame is provided at their outer edges to ensure the overall strength of the light-transmitting arc plate. Hydraulic spring rods can be assembled on the upper protective plate 121 and the lower protective plate 122, and the other ends of the hydraulic spring rods are hinged to the installation hood 11 to ensure the stability of the self-position and attitude of the upper protective plate 121 and the lower protective plate 122 in the open state.

[0051] The setting of the universal wheel 13 facilitates the movement of the entire seedling-raising device 1 in the workshop of the seedling-raising factory. And a braking brake is equipped on the universal wheel 13. In the locked state of the braking brake, the seedling-raising device 1 can be fixed to restrict its ineffective movement and ensure the stable operation of the seedling-raising device 1.

[0052] To ensure that the lifting bracket 23 in the light control component can stably move up and down in the vertical direction, the following technical solution is provided.

[0053] An assembly cavity 14 is provided at the bottom of the installation hood 11. The light control component further includes a telescopic cylinder 25 arranged in the assembly cavity 14.

[0055] The matching combination of the guide seat 112 and the guide through groove 231 can ensure the stable up and down movement of the lifting bracket 23 in the vertical direction. During the process of controlling the telescopic cylinder 25 to expand and contract, the lifting bracket 23 can be driven to stably move up and down in the vertical direction, and then drive the tray brackets 22 of each layer to deflect synchronously through the support link 24.

[0056] To ensure the stable installation of the spray pipe 31 and the fluorescent lamp 21 in the installation hood 11, and at the same time to realize the independent water supply to each layer of the spray pipe 31 to independently adjust the humidity of the seedlings in each layer of the seedling-raising trays, the following technical solution is provided.

[0057] A plurality of horizontally arranged mounting plates 15 are fixedly installed in the mounting hood 11. The mounting plates 15 are arranged above the corresponding tray support plates.

[0058] The arrangement of the mounting plate 15 can ensure the stable installation of the spray pipe 31 and the fluorescent lamp 21 above the corresponding tray support 22. After the water supply main pipe 32 extends out of the mounting hood 11, it is connected to a water source. When the water supply pump 34 works, clean water can be transported through the water supply main pipe 32 and the water supply branch pipes 33 to the spray pipes 31 of each layer. By independently controlling the electromagnetic switch valve A331 on each spray branch pipe, the sprinkling state of each spray branch pipe can be independently adjusted.

[0059] To ensure that the temperature control component can extract external air and heat it to a specific temperature, ensure that the heated air can be stably supplied to each layer of air distribution plate, and at the same time facilitate the independent adjustment of the painting state of each layer of air distribution plate, the following technical solutions are provided.
