Description

Technical Field

[0001] The utility model relates to the technical field of seedling cultivation, in particular to a constant temperature device for cultivating seedlings. Background Technique

[0002] With the increasing severity of environmental pollution, garden construction is particularly important, which can effectively prevent soil erosion and purify the air. However, during the process of seedling cultivation, especially for temperature-sensitive seedlings, special cold protection measures are often required. With the development of agricultural technology and the growth of market demand, the traditional seedling cultivation methods have gradually been unable to meet the needs of modern agricultural production. In order to improve the quality and production efficiency of seedlings, it has become a trend to use modern greenhouse greenhouses for constant temperature cultivation of seedlings.

[0003] Under high-temperature conditions, seedlings may experience heat stress, resulting in growth retardation, leaf wilting, and even death. Under low-temperature conditions, the growth of seedlings will also be affected, and they may even die due to freezing damage. By providing an ideal growth environment for the seedlings in the greenhouse, but the greenhouse is too large, and it takes a lot of energy to switch the sunshade net and the heat preservation film. By automatically and precisely controlling the growth temperature of the seedlings, the healthy growth of the seedlings can be promoted while saving energy. Content of the Utility Model

[0027] Furthermore, the thermal sensing controller 2 includes two single detection thermal sensing controllers for detection and control, and is used to make circuit control instructions according to the temperature in the greenhouse.

[0028] Furthermore, the temperature control mechanism 3 includes a sliding frame 301, the sliding frame 301 is fixedly connected to the left and right sides of the seedling-raising shed 1, a sunshade net retracting rod 303 and a heat preservation film retracting rod 304 are rotatably connected to the sliding frame 301, the sunshade net retracting rod 303 is arranged above the heat preservation film retracting rod 304, the sunshade net retracting rod 303 and the heat preservation film retracting rod 304 are meshed and connected, a film reel rod 305 and a net reel rod 306 are slidably connected to the sliding frame 301, the film reel rod 305 is connected to the heat preservation film retracting rod 304 through the heat preservation film, the net reel rod 306 is connected to the sunshade net retracting rod 303 through the sunshade net, the net reel rod 306 is arranged above the film reel rod 305, the sunshade net retracting rod 303 and the heat preservation film retracting rod 304 reach opposite rotation directions through the meshing relationship, and the temperature in the shed is detected by the thermal sensing controller 2 (the sensor and control element can select the GS1-4G temperature sensor and the AC contactor) and the detection result is converted into an electric signal to control the rotation of the motor inside the motor housing 302, and the motor drives the sunshade net retracting rod 303 and the heat preservation film retracting rod 304 to perform retracting and releasing actions to complete the temperature adjustment in the shed.

[0029] Embodiment 2:

[0030] Please refer to Figures 1-5, and in combination with Embodiment 1, it is further obtained that the spray fertilization mechanism 4 includes a stepping motor 401, the stepping motor 401 is fixedly connected to the carriage 301, the output end of the stepping motor 401 is fixedly connected to a stirring rod 404, a water collecting tank 402 is fixedly connected to the carriage 301, the stirring rod 404 is rotatably connected in the water collecting tank 402, a fertilizer tank 403 is installed above the water collecting tank 402, a baffle 408 is fixedly connected to the stirring rod 404, a spray pipe 405 is fixedly connected below the stepping motor 401 on the water collecting tank 402, the spray pipe 405 is communicated with the water collecting tank 402, a sleeve gear 406 is rotatably connected to the spray pipe 405, a vortex plate 407 is fixedly connected to the sleeve gear 406. After the temperature in the shed is higher than the temperature setting of the thermal sensing controller 2, the thermal sensing controller 2 controls the synchronous rotation of the output end of the stepping motor 401. The sleeve gear 406 pumps the rainwater inside the water collecting tank 402 to the spray pipe 405 through the vortex plate 407 under the output of the stepping motor 401. The pressure of the rainwater increases in the spray pipe 405 and forms a spray from the spray pipe 405 to cool down the shed. At the same time, the baffle 408 rotates during the output of the stepping motor 401. After the baffle 408 rotates and disengages from the fertilizer tank 403 during the rotation process, the inner notch of the fertilizer tank 403 is opened, and the fertilizer falls into the water collecting tank 402. The fertilizer is sent into the greenhouse in the form of a spray through the stirring of the stirring rod 404 and the thrust of the vortex plate 407. While cooling down, the demand of the wood seedlings for phosphate fertilizer under high temperature conditions is met, and the growth environment of the wood seedlings is improved.

[0031] Further, the thermal sensing controller 2 is electrically connected to the motor inside the motor housing 302 and the stepping motor 401 respectively.

[0032] Further, the middle part of the sunshade net is fixedly connected to the sunshade net retractable rod 303 and the insulation film retractable rod 304, and the middle part of the insulation film is fixedly connected to the insulation film retractable rod 304.

[0033] Further, the baffle 408 is used to plug the notch of the fertilizer tank 403 at intervals.

[0034] During the actual operation process, when this device is in use, the temperature set by the thermal sensing controller 2 is generally from 15 degrees to 30 degrees. The rotation angle that the stepper motor 401 can set is an integer multiple of one revolution. When the temperature inside the shed is higher than the maximum value of the set temperature, the thermal sensing controller 2 controls the operation of the motor inside the motor housing 302 and the stepper motor 401 through the received electrical signal. The motor inside the motor housing 302 drives the sunshade net retractable rod 303 and the insulation film retractable rod 304 to rotate through meshing. The rotation directions of the sunshade net retractable rod 303 and the insulation film retractable rod 304 are opposite. According to the rotation direction of the motor, the sunshade net retractable rod 303 unfolds the sunshade net during rotation, and the insulation film retractable rod 304 retracts the insulation film during rotation, so as to isolate the solar radiation inside the shed and reduce the temperature inside the shed. When the temperature is lower than the set value, the thermal sensing controller 2 controls the sunshade net retractable rod 303 to retract and the insulation film retractable rod 304 to unfold, so as to achieve the purpose of keeping the shed warm and increasing the temperature through sunlight. At the same time, during the rotation of the output end of the stepper motor 401, the stirring rod 404 drives the baffle 408 to rotate. During the rotation of the baffle 408, it disengages from the notch of the fertilizer tank 403, and the fertilizer inside the fertilizer tank 403 falls into the water collecting tank 402. The vortex plate 407 squeezes the water inside the water collecting tank 402 through the output of the stepper motor 401 and forms a spray, fertilizing the seedlings in the high-temperature environment while cooling down, and improving the utilization effect of the fertilizer.
