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

A kind of can the green house of vegetables of snow melt

Technical field

The invention belongs to agricultural technology field, be specifically related to a kind of can the green house of vegetables of snow melt, prevent green house of vegetables from too much caving in because accumulated snow.

Background technology

Nowadays along with the development of green house of vegetables, people can have increasing vegetables in improper season in the winter of cold.But, at vast northern area, due to cold weather, the heat insulation effect of green house of vegetables just seems most important, and, because green house of vegetables is in order to get better light, all plastic foil is laid on as on the arch bar of support frame, the weight capacity of its plastic foil is poor, therefore after snowing heavily, easily because accumulated snow causes and caves on green house of vegetables, very large economic loss is brought to vegetable grower, and the snow removing device cost of more existing peripheral hardwares is too large at present, and be not suitable for the ceiling environment of green house of vegetables, use pretty troublesome, therefore need to provide a kind of green house of vegetables that can remove the snow in time, the generation of accumulated snow just can be avoided snowy while, thus avoid green house of vegetables to be crushed by accumulated snow.

Summary of the invention

The object of this invention is to provide a kind of can the green house of vegetables of snow melt, by arranging heat abstractor below the plastic foil of green house of vegetables, improving the temperature of plastic foil self, by the snow melt on the plastic film that falls, and then avoiding the formation of too much accumulated snow.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of can the green house of vegetables of snow melt, at the back of booth, cob wall is set, and to booth two ends, horizontal flue is set respectively from cob wall middle part along cob wall length direction, and be connected by the exhaust opening of blower fan with the heating furnace being located at booth two ends, horizontal flue is provided with multiple vertical flue, vertical flue upper end passes and is communicated with radiator from cob wall, described radiator is be arranged in parallel by the main pipeline be interconnected and branch pipe(tube) and forms, and branch pipe(tube) is symmetricly set on the both sides of main pipeline, main pipeline is fixed in the groove for the arch bar upper surface of supporting plastic film, the smoke exhaust pipe arranged along booth length direction and the outlet of described radiator, cigarette in heating furnace enters in radiator by horizontal flue and vertical flue, by the plastic foil heating above radiator, to avoid the formation of accumulated snow.

Further, the length of described radiator is 1/4 ~ 1/6 of arch bar length.

Further, the tank for collecting snowmelt is set in the lower end of booth sunny side side, and the snowmelt of collection can be utilized to irrigate.

Further, in described green house of vegetables growing vegetables face lower than ground level.

Compared with prior art, the present invention has following beneficial effect:

First, the present invention arranges flue in insulation cob wall, and the high-temperature flue gas produced by heating furnace imports in the radiator below plastic foil, plastic foil is heated, thus the snow fallen on the plastic film is melted in time, and along under the slope current of plastic foil, thus avoid on booth, produce too much accumulated snow;

Second, in the present invention, the length of radiator is 1/4 ~ 1/6 of arch bar length, the decay of heat can be reduced on the one hand, ensure that heat is better concentrated on a heat sink, play the object of snow melt, on the other hand, plastic foil due to green house of vegetables be one domatic, by being melted the normal erosion of snow-broth, can avoid forming accumulated snow on domatic, therefore not needing the length of radiator to be arranged to the object that length the same as arch bar can play snow removing;

3rd, in cob wall, arrange the insulation effect that flue can improve cob wall, and in the present invention, growing vegetables face is lower than ground level, belongs to semi-underground structure, ground temperature is minimum by ectocine, further strengthens the insulation effect to green house of vegetables.

Embodiment

Below in conjunction with accompanying drawing, by embodiment, the present invention is further illustrated.

As shown in the figure, a kind of can the green house of vegetables of snow melt, adopt semi-underground type, namely a heatable adobe sleeping platform is excavated on ground, be growing vegetables face in heatable adobe sleeping platform, trapezoidal cob wall is built in the shade surface barrier, sunny side builds brick wall by laying bricks or stones, the pillar for supporting plastic film and arch bar is fixedly installed between cob wall and brick wall, and plastic foil is fixedly installed on arch bar, build respectively at the two ends of heatable adobe sleeping platform and build gable, and the surge chamber for being incubated, and heating furnace is set in surge chamber, flue is built by laying bricks or stones in described cob wall, flue comprises horizontal flue and the vertical flue be arranged on horizontal flue, horizontal flue is two, cob wall one end is extended to along its length respectively in the middle part of cob wall, and be communicated with by the outlet flue of blower fan with described heating furnace, vertical flue is evenly arranged on horizontal flue, and upwards pass cob wall and be communicated with the radiator be arranged on below plastic foil, radiator makes serpentine configuration by the metal that thermal conductivity is good, its length is 1/6 of described arch bar, radiator is connected to form by main pipeline and branch pipe(tube), main pipeline is fixedly installed in the groove of described arch bar upper surface, the both sides being arranged on main pipeline of branch pipe(tube) symmetry, the entrance of radiator is located on main pipeline, the outlet of radiator is arranged on branch pipe(tube), and the smoke exhaust pipe passing through booth with is communicated with, the high-temperature flue gas produced through heating furnace enters in radiator by flue, by the plastic foil heating above radiator, melt the accumulated snow fallen on the plastic film, snowmelt collects by the tank of green house of vegetables sunny side side the irrigation being used for vegetables.

In order to improve snow melt ability, the bottom portion of groove on described arch bar top offers multiple louvre, so that heat in radiator can heat radiating via hole, plastic film above Fast Heating arch bar, by snow melting, meanwhile, in order to strengthen the bearing capacity at arch bar upper grooves place, between groove both sides and bottom portion of groove louvre, bury reinforcing bar underground respectively.

As distortion, the entrance of described radiator arranges valve, in described cob wall, the end of horizontal flue is connected with smoke exhaust barrel, and exhaust valve is set in smoke exhaust barrel, when not needing to carry out snow removing, can radiator valve be closed, open exhaust valve, while ensureing to heat cob wall, stop the heating of radiator.
