[0001] The utility model relates to the technical field of vegetable planting, in particular to an automatic ventilation device for a vegetable planting greenhouse. Background Art

[0002] Vegetable greenhouse technology is an agricultural technology that uses greenhouse conditions to improve the efficiency and yield of vegetable cultivation. The main goal is to create a microclimate suitable for plant growth by controlling environmental factors such as temperature, humidity, and light. At present, there are basically two ways to ventilate vegetable greenhouses. One is to use ventilation fans for ventilation. Installing ventilation fans can easily lead to air circulation at the installation location of the ventilation fans. When encountering vegetable greenhouses in cold weather, the internal temperature drops sharply at night, seriously affecting the growth of vegetables in the vegetable greenhouse. The other method is to flip up the thermal insulation plastic film on the top of the vegetable greenhouse for ventilation during the day and re-cover it at night. The process is relatively cumbersome, which increases the workload of the personnel involved, thereby reducing the use effect of the ventilation device of the vegetable greenhouse.

[0003] Therefore, it is necessary to develop an automatic ventilation device for vegetable growing greenhouses. Utility Model Content

[0010] Preferably, a water baffle is installed above the outer wall of one side of the ventilation box, and a ventilation port is opened on the surface of the outer wall of one side of the ventilation box.

[0011] Preferably, the output shaft of the motor is fixedly connected to one end of the rotating shaft via a coupling, and a movable seat is installed on the outer wall of the rotating shaft.

[0012] Preferably, a threaded hole is provided at the center of the surface of the movable seat, and the inner wall of the threaded hole is threadedly connected to the outer wall of the rotating shaft.

[0013] Preferably, a connecting rod is installed at the bottom of the movable seat, a fixed seat is installed at the bottom end of the connecting rod, and one side outer wall of the fixed seat is fixedly connected to the upper side outer wall of the baffle.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The fan is driven by a motor to move the baffle out of the vent hole and move it to the outside of the vent hole so that the vent hole is not blocked. The ventilation of the vegetable growing greenhouse can be carried out normally. The ventilation of the vegetable growing greenhouse can be carried out by the fan. No human operation is required during the ventilation. Only the electrical equipment such as the motor and the fan need to be operated automatically to reduce the workload of the personnel involved.
