Temperature and humidity control machine based on modern agricultural greenhouse

Abstract

The invention discloses a temperature and humidity control machine based on a modern agricultural greenhouse, wherein a shell is fixedly installed in a ceiling, an air inlet with a downward opening is formed in a bottom surface of the sell, an air outlet is formed in a rear side of the air inlet, a ventilation mechanism capable of controlling air temperature in the greenhouse and dehumidifying is disposed between the air outlet and the air inlet, when a thermometer detects a temperature difference, the thermometer sends a signal to a first motor, a condenser pipe and a heating wire through an electric wire and a control circuit, the first motor drives a first cone pulley to rotate by the rotation of a power shaft, the first cone pulley drives a transmission shaft to rotate through a second cone pulley so as to achieve a ventilation function of the air in the greenhouse, a spray mechanism is disposed in the temperature and humidity control machine disclosed by the invention, which can spray by using water in a water cavity, but also can drive a thread block and an atomizer to move left and right by using a rotating rod, the humidification range is increased to ensure a more uniform humidification effect in the greenhouse, a rotating mechanism can control a baffle in the ceiling can be controlled to rotate for opening while dehumidifying, and the evaporation of water droplets sprayed by the spray mechanism is accelerated by enhancing the illumination.

Description

technical field [0001] The invention relates to the field of temperature and humidity control in greenhouses, in particular to a temperature and humidity control machine based on modern agricultural greenhouses. Background technique [0002] Based on the rapid development of modern agricultural technology, greenhouse technology has developed rapidly. Greenhouse technology allows people to eat off-season vegetables in the current season. As people's living conditions get better and better, people have higher requirements for the variety and quality of greenhouse plants. It is getting higher and higher, and the temperature in the greenhouse is higher than the outside temperature. If the humidity in the greenhouse is too high, water droplets will condense on the roof of the greenhouse. The condensed water dripping on the leaves will affect the quality of vegetables, and the temperature and humidity in the greenhouse are generally high. It is derived from the induction, and it i...

[0002] Based on the rapid development of modern agricultural technology, greenhouse technology has developed rapidly. Greenhouse technology allows people to eat off-season vegetables in the current season. It is getting higher and higher, and the temperature in the greenhouse is higher than the outside temperature. If the humidity in the greenhouse is too high, it is easy to condense water droplets on the roof. The condensed water dripping on the leaves will affect the quality of vegetables, and the temperature and humidity in the greenhouse are generally high. Derived from induction, it is easy to produce observation deviations, resulting in reduced vegetable production, etc., which reduces economic benefits

[0003] Although the general greenhouse temperature and humidity controller is efficient enough to control the humidity in the greenhouse, it is difficult to reuse the water collected during dehumidification, resulting in a waste of water resources. When humidifying, the general greenhouse temperature and humidity controller It is difficult to humidify the shed on a large scale, which may cause the moisture in a certain area to be too concentrated, resulting in an uneven humidification effect in the shed. Secondly, the general greenhouse temperature and humidity controller cannot control the light intensity in the shed. When the humidified water does not evaporate fast enough, it may form stagnant water
