The invention discloses an automatic
greenhouse based on electromagnetic suction, and relates to the technical field of agricultural equipment. The automatic
greenhouse comprises a
supporting wall, a vaulting shaft, a base and a heat preservation quilt. A folding rod is arranged on the top of the
supporting wall and used for folding and unfolding the heat preservation quilt; one end of the vaulting shaft is connected with the
supporting wall, the other end of the vaulting shaft is fixed to the base, a layer of
electromagnetic coil is wound around the surface of the vaulting shaft, and the heat preservation quilt is sucked and fixed after being powered on; The folding rod and a screw rod are drive by a motor to fold or unfold the heat preservation quilt. By arranging the motor, the folding rod and the screw rod, the heat preservation quilt can be folded and unfolded, the automatic
greenhouse has the advantages of being simple, practical and easy to operate, the distance between the heat preservation quilt and the vaulting shaft is limited through a pressing rod, the layer of
electromagnetic coil is wound around the surface of the vaulting shaft, and an iron sheet on the heat preservation quilt is attracted through
electromagnetism, so that the heat preservation quilt is fixed, a film can be fixed without manpower, operation procedures are simplified, workloads of workers are reduced, and the working efficiency can be improved.
