Abstract

The invention belongs to the technical field of greenhouse temperature rising equipment, in particular relates to a mechanical straw temperature rising device for a sunlight greenhouse and solves the problem that the conventional sunlight greenhouse is difficult and expensive to warm. The mechanical straw temperature rising device for the sunlight greenhouse comprises a furnace outer cylinder, wherein the furnace outer cylinder is provided with a fuel port and an ash outlet; a furnace grate assembly is arranged between the fuel port and the ash outlet; a conical primary burner, a cylindrical secondary burner, a reversely conical fire extinction dust reducer and a conical secondary heat exchanger are arranged inside the furnace outer cylinder from bottom to top; a hot air outlet is formed on the furnace outer cylinder; and a plurality of vertical tube nests are arranged outside the secondary burner. The device has the advantages that: various waste straws in rural areas are utilized asfuels to supply heat to the sunlight greenhouse in winter, the heat energy utilization rate is high, the sunlight greenhouse is uniformly heated, has no dust discharge and is environment-friendly, and a good growth environment is provided for crops; and agricultural output is improved, farmer benefits are improved, and socialistic new countryside construction is powerfully promoted.

Description

technical field [0001] The invention belongs to the technical field of greenhouse warming equipment, and in particular relates to a solar greenhouse mechanical straw warming device. Background technique [0002] my country's facility agriculture has developed rapidly in recent years, and it is another important measure to benefit the people after the implementation of my country's grain production increase plan. However, due to the high energy prices at present, the problem of difficult and expensive heating in winter in my country's protected agricultural solar greenhouses has become a major problem that plagues the sustainable development of this industry. According to statistics, due to the limitation of heating costs in China, 85% of solar greenhouses in my country do not have heating devices, and the indoor temperature in winter nights is usually below 9°C. The low temperature environment in the greenhouse limits the growth of agricultural products. If the indoor tempe...
