Description
Technical Field
[0001] The utility model relates to the technical field of granary protection and dust removal, and particularly relates to a protection and dust removal device for a granary ventilation opening. Background Art
[0002] China is a large agricultural country with a long history of grain production and storage. Among them, the storage of grain is a continuation of agricultural cultivation, and the storage technology has developed along with the development of agriculture. A granary is a place for grain storage. An air vent needs to be arranged in the granary to facilitate the air change in the granary. When arranging the air vent, a protection and dust removal device needs to be arranged.
[0003] In the prior art, Chinese Patent Publication No. CN108781788B discloses a protection and dust removal device for a granary ventilation opening, which includes an installation frame. The inner walls of the opposite sides of the installation frame are provided with receiving grooves. A plurality of prismatic rubber rods are arranged in the installation frame. The two ends of the rubber rod are respectively connected with the inner walls of the two receiving grooves. A movable block is slidably sleeved on the rubber rod. The invention makes the movable block move back and forth on the rubber rod through the cooperation of a motor, a rotating shaft, a wire winding cylinder and a connecting rope, so as to generate static electricity through the friction between the first hair layer and the rubber rod. In this way, the static electricity can adsorb the dust in the ventilation opening and cause harm to pests and birds, etc., so as to prevent dust and birds from entering the granary. In addition, the movable block moving back and forth can push the dust on the rubber rod into the receiving groove, which is convenient for people to deal with the dust and the corpses of pests, without the need for complex operations such as replacing the mesh plate and cleaning the mesh plate, and at the same time, it can prevent pests and birds from entering the granary.
[0004] However, when the utility model is actually used, dust removal is carried out by means of static electricity, and the dust removal effect may be limited, resulting in poor dust removal. There are gaps between the rubber rods. Therefore, when the air flow rate is too fast, it is easy to directly enter the ventilation opening without being adsorbed in time. Therefore, improvement is needed. Summary of the Utility Model
