Abstract
The invention discloses a greenhouse heating device. The device comprises a greenhouse and a heating system, a temperature sensor is arranged in the greenhouse, and the heating system comprises a heater, a water tank, a water pump and a cooling coil, wherein a temperature sensor is arranged at an inlet of the heater, an inlet of the water tank is connected with an outlet of the heater, a temperature sensor is arranged at an outlet of the water tank, a water level sensor is arranged in the water tank, an inlet of the water pump is connected with an outlet of the water tank, the cooling coil isinstalled under the ground of the greenhouse, an inlet of the cooling coil is connected with an outlet of the water pump, and an outlet of the cooling coil is connected with the inlet of the heater. According to the greenhouse heating device, the cooling coil is installed under the ground in the greenhouse, an existing terrestrial heat line can be replaced, planting soil in the greenhouse is heated, the temperature of the soil is raised, and growth of crops is promoted. The heating system is simple in structure, in the cooling coil, water serves as a heat-carrying medium, leakage cannot occur,safety and reliability are achieved, environmental friendliness is achieved, and pollution does not exit.
Description
technical field [0001] The invention relates to the field of agricultural planting equipment, in particular to a greenhouse heating device. Background technique [0002] The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, the greenhouse has been used for potted flower and cut flower cultivation; fruit tree production is used for cultivating grapes, strawberries, watermelons, melons, peaches and citrus, etc.; The growth of crops is affected by many factors such as the length of light time, carbon dioxide concentration, temperature, and humidity. The optimal growth environment for different crops is often different, which requires us to create different growth environments for different crops. Among them, temperature plays a decisive role in the growth of crops. When planting crops, in order to shorten the germination time of seeds and inc...
