Multi-span greenhouse

Abstract

The invention discloses a multi-span greenhouse, and belongs to the technical field of planting greenhouses. The multi-span greenhouse comprises a plurality of independent greenhouses, a film rolling device and a ventilation device, the multiple independent greenhouses are installed together at equal intervals, the film rolling device is arranged at the side ends of the independent greenhouses, and the ventilation device is arranged at the top ends of the independent greenhouses; each independent greenhouse comprises a plurality of main stand columns, a plurality of side auxiliary stand columns, a greenhouse head end stand column and a greenhouse face, the multiple main stand columns are arranged on the ground at equal intervals, the multiple side auxiliary stand columns are distributed in the middles of the main stand columns at equal intervals, and by symmetrically arranging the two rows of the multiple main stand columns, the greenhouse faces are arranged on the main stand columns to form the independent greenhouses, the side auxiliary stand columns and the greenhouse head end stand columns can play a role in fixing the greenhouse faces, and the multiple independent greenhouses can be installed together to form the multi-span greenhouse.

Description

technical field [0001] The invention relates to the technical field of planting greenhouses, in particular to a multi-span greenhouse. Background technique [0002] Planting greenhouses are generally used to grow vegetables, cultivate fruit seedlings, saplings, and potted plants. It is a frame-covered structure with excellent thermal insulation performance. Through the use of greenhouses, people can eat off-season vegetables, which can significantly improve the survival rate and quality of fruit seedlings, saplings, and potted plants. Traditional planting greenhouses generally use bamboo or steel structures covered with one or more layers of plastic film to form a greenhouse space. The outer film can well prevent the loss of carbon dioxide produced by the growth of internal plants, so that the shed has a good Insulation effect. At present, the technology of using plastic greenhouses to grow vegetables in various regions of our country has been widely popularized. Among the...
