Agricultural intelligent ventilation control device

The utility model discloses an agricultural intelligent ventilation control device which comprises a greenhouse body, ventilation boxes are embedded in the two sides of the greenhouse body, through arrangement of a temperature sensor and an air quality sensor, the air quality and the temperature in the greenhouse can be monitored in real time, and when the air quality is poor or the temperature is too high, the ventilation boxes can be turned on and turned off. By setting data of the switch box, the fan body can be automatically started to rotate, air circulation in the greenhouse can be accelerated, the purposes of improving the air quality and reducing the temperature are achieved, after the temperature or the air quality reaches a set value, the fan can be automatically stopped, and the fan is prevented from being damaged. Meanwhile, a switch box can automatically start a motor to drive a threaded rod to rotate, rotation of the threaded rod can drive a threaded sleeve which is moved in a limited mode to mo
