Abstract

The utility model relates to a stratum heating device of agricultural greenhouse. The utility model discloses by heat pipe furnace or ordinary water heating stove, the heating pipeline is constituteed to the pipeline, be equipped with the water pump on the pipeline, blast pipe and temperature meter, heat the water of suitable temperature in heat pipe furnace or ordinary hot-water stove, flow into the pipeline through the delivery port, flow through the water pump again after soil heat absorption and get back to in heat pipe furnace or ordinary hot-water stove, can improve the temperature of stratum in the big-arch shelter greatly like this, the phenomenon of "head heat foot cold" in having solved the growth of vegetables in the canopy, the energy saving improves the output of vegetables, easily generally promote.

Description

Booth stratum heating device

The utility model relates to a kind of stratum heating device of agricultural booth.

The northern area of China climate cold, the people that live in here are difficult to have multiple fresh vegetables in winter, and since greenhouse by solar heat plastics booth occurred, this problem had obtained improving greatly.But in some area, though the environmental temperature in the canopy is higher, ground temperature is not high, the phenomenon of " a hot pin is cold " promptly occurs, still influences the particularly ordinary production of melon-fruit-like vegetable of vegetables, has directly influenced the output of vegetables yet.The employing that has the in recent years methods such as a heatable brick bed, electrical heating of lighting stove, light a fire increase ground temperature, but because difficult control of temperature or promote the use of because of fuel, the too high large tracts of land that is difficult to of power cost.

The heating device that the purpose of this utility model is to provide a kind of energy savings, can improves and control the inner greenhouse ground temperature.

The utility model is finished like this: form heating pipe line by hot-water heating stove, pipeline, water pump, blast pipe and water thermometer are housed on the pipeline.Also can connect one on the pipeline and be sheathed on the black plastic pipeline that directly can shine sunlight in the canopy, on the black plastic pipeline control valve is housed.For improving hot benefit, the hot-water heating stove can use the heat pipe-type stove.

The advantage that compared with the prior art the utility model has energy savings, can improve yield of vegetables, cost is low, be easy to promote.

Description of drawings

Fig. 1 is a combination schematic diagram of the present utility model

Fig. 2 is the combination schematic diagram of another embodiment of the utility model

The figure number explanation

1--hot-water heating stove 2--delivery port 3--pipeline 4--water pump

5--blast pipe 6--black plastic pipeline 7--water thermometer 8--control valve

Describe in detail below in conjunction with embodiment

Select for use the heat pipe oven 1 of light water radiator or hot high efficiency to form heating pipe line with the pipeline 3 that is embedded in underground appropriate depth.Water pump 4, blast pipe 5 and water thermometer 7 are housed on the pipeline.Be heated to the water of proper temperature from heat pipe oven or light water radiator 1, flow in the pipeline 3 through delivery port 2, the water pump 4 of flowing through again after the soil heat absorption is got back in heat pipe oven or the light water radiator 1.In pipeline, be equipped with blast pipe 5, can discharge the air that current enter in flowing.On heat pipe oven or the common water heater 1 water thermometer 7 is housed, is used to observe the water temperature in the stove.

Another embodiment: on the basis of a last embodiment, in canopy, increase the black plastic pipeline 6 that a cover can directly absorb sunlight, control valve 8 is housed on it.When stopping by day heating hot-water heating stove 1, utilize the direct irradiation of the sun, after 6 heat absorptions of black plastic pipeline,, be embedded in the underground pipeline 3, can reach and improve in the canopy and the effect of formation temperature through control valve 8 inflows with the heating of the water in the pipe to plastic greenhouse.

Claims

1. a booth stratum heating device is characterized in that: form heating pipe line by hot-water heating stove (1), pipeline (3), water pump (4), blast pipe (5) and water thermometer (7) can be housed on the pipeline.

2. booth according to claim 1 stratum heating device is characterized in that also can connecting on the pipeline cover and is set up in the interior black plastic pipeline (6) of canopy.

3. booth according to claim 2 stratum heating device is characterized in that being equipped with on the black plastic pipeline (6) control valve (8).

4. booth according to claim 1 stratum heating device is characterized in that hot-water heating stove (1) can adopt the heat pipe oven of hot high efficiency.
