Abstract

The invention discloses an adjustable granary ventilation opening device, and relates to the technical field of granary ventilation equipment. The adjustable granary ventilation opening device comprises a mounting outer cylinder, an adjusting sleeve ring and a second support, a first support is arranged on the inner side wall of the other end of the mounting outer cylinder, a plurality of rotatingshafts are symmetrically arranged on the first support and fixedly connected with fan blades, the adjusting sleeve ring is rotatably connected with one end of the mounting outer cylinder, driving gears are arranged on the inner side wall of the adjusting sleeve ring, the second support is arranged on the inner side wall of one end of the mounting outer cylinder, a plurality of fixing seats are symmetrically arranged on the second support and rotatably connected with nuts, driven gears are fixedly connected onto the nuts and internally engaged with the driving gears, lead screws are arranged in the nuts in a matched manner, a shaft ejector sleeve is arranged at one end of each lead screw, two pull rods are rotatably connected onto each shaft ejector sleeve, and one end of each pull rod isrotatably connected onto the inner side face of the corresponding fan blade. The fan blades are rotatably adjusted by gear components, lead screw components and the like, and the air quantity of an air opening is adjusted.

Description

technical field [0001] The invention belongs to the technical field of granary ventilation equipment, in particular to an adjustable granary vent device. Background technique [0002] A large amount of rice and other grains are placed in the granary. In order to avoid moisture, the granary is usually a relatively sealed space. In this way, the grain is prone to mold and insects if it is stored for a long time, which will affect the storage time of the grain. The grain needed for this needs regular ventilation. [0003] The current way is to open a through hole on the wall of the granary, and install the vent at the through hole. The existing vent generally includes a shell that matches the shape of the through hole. The shell is provided with an air passage, and the entrance of the air passage A sealing cover is provided, and the air passage is sealed by the sealing cover and the sealing strip at the entrance. When the granary needs to be ventilated, the sealing cover is ope...
