The invention relates to the technical field of agricultural production equipment, in particular to an intelligent constant-temperature greenhouse capable of automatically removing snow. The greenhouse comprises a greenhouse body, a constant temperature module, a supporting module, two unwinding modules, two tight supporting modules, two auxiliary elastic tightening assemblies, a snow removing mechanism, and a snow sweeping reciprocating mechanism. The constant temperature module is arranged on the greenhouse body, the supporting module is arranged across the greenhouse body, and the top of the supporting module is provided with a pressure sensor; and the two unwinding modules are symmetrically arranged at the two sides of the supporting module, the two tight supporting modules are symmetrically arranged at the two sides of the supporting module, the two auxiliary elastic tightening assemblies are symmetrically arranged at the two sides of the supporting module, the snow removing mechanism is arranged on the supporting module, and the snow sweeping reciprocating mechanism is arranged on the supporting module. The output end of the snow sweeping reciprocating mechanism is connectedwith a non working part of the snow removing mechanism. According to the technical scheme, greenhouse body protection can be automatically conducted on the greenhouse, accumulated snow is removed in real time, and the production effect of agricultural and sideline products is effectively guaranteed and improved.
