Vegetable greenhouse capable of melting snow

Abstract

The invention discloses a vegetable greenhouse capable of melting snow. A radiator is arranged below a plastic film of the vegetable greenhouse to raise the temperature of the plastic film, in order to melt the snow on the plastic film and further avoid accumulation of too much snow; an earth wall is arranged on the shade side of the greenhouse; horizontal flues are respectively arranged from the middle part of the earth wall to the two ends of the greenhouse in the earth wall length direction and connected with smoke vents of heating furnaces arranged at the two ends of the greenhouse; a plurality of vertical flues are arranged on the horizontal flues; upper ends of the vertical flues penetrate through the earth wall and then are communicated with the radiator; the radiator is formed by arranging a master pipeline and branched pipelines, which are interconnected, in parallel; the smoke vent in the greenhouse length direction is communicated with an outlet of the radiator; the smoke in the heating furnaces passes through the horizontal flues and the vertical flues and then enters into the radiator, so as to heat the plastic film above the radiator and avoid snow accumulation.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a vegetable greenhouse capable of melting snow, which prevents the vegetable greenhouse from collapsing due to excessive snow accumulation. Background technique [0002] Nowadays, with the development of vegetable greenhouses, people can eat more and more off-season vegetables in the cold winter. However, in the vast northern regions, due to the cold weather, the thermal insulation effect of the vegetable greenhouses is very important. Moreover, in order to better light the vegetable greenhouses, plastic films are laid on the arches as the supporting framework. The load-bearing capacity of the plastic film is poor, so after heavy snowfall, the vegetable greenhouses are prone to collapse due to snow accumulation, which brings great economic losses to the vegetable farmers. At present, some existing peripheral snow removal devices are too expensive and not The roof...
