Description
The utility model relates to a kind of device of frost protection infringement in crops and orchard production, belongs to the frost protection field.
Be the most tender and lovely, the easiest seasons that come to harm of crops spring, therefore prevents that in spring the frost of crops and orchard production process is one of primal problem.
Two kinds of dissimilar frosts are arranged: a kind of is heat release or radiation frost; A kind of is that convection current rises and freezes.The former is that the earth produces in fine day release heat in evening, and this is the inverse process that the solar radiation on daytime heats up the earth.At this moment, be the earth to the atmosphere release heat, air turns cold from bottom to top extremely lentamente.Therefore the temperature of air layer is low than the temperature of top air layer below, and people are called temperature inversion layer to this bottom air layer colder than top.About 10 meters of temperature inversion layer built on stilts, thick about 30 meters.It is higher about 5 ℃ than surface temperature.On this temperature inversion layer, temperature begins again to descend.Second kind is that convection current rises and freezes, and it takes place when bulk cold air group or polar air are come crops or orchard.
People prevent the method and apparatus of frost injury always in searching.The most general method is to burn with bavin, with various fuel heaters, windmill or propeller, uses helicopter that flies in the sky, orchard or the like.
To go up frost be highly effective to heater to anti-, but they have a common shortcoming, and that is exactly owing to the thermal efficiency is low excessively, consumes a large amount of fuel and cause operating cost very high.To very high temperature, the very fast rising of hot-air produces chimney " effect " to heater air heat.Like this ambient air is not just produced the radiation exothermic effect.Because heater consumes a large amount of fuel, thereby produces a large amount of pollutions.
Except heater, be exactly helicopter and propeller.They all are that hot-air is blown down from temperature inversion layer, and it is mixed with subaerial colder air.
Except device recited above; the inventor also knows uruguayanly a kind ofly have Patent right device and be used for protecting the mandarin orange planting garden; this device also be utilize temperature inversion layer than hot-air; with one 10 meters or 10 meters high above funnels; a fan blower is arranged at the bottom of funnel; allow cold air down blow to crops or orchard, with frost protection by making hot air.
The inventor knows that also there is a grower in Chilean EI Olivar county, use be a kind of axial flow blower that belongs to the turbine sprayer, he has added a heater on axial flow blower, in order to hot-air is blowed to his vineyard.Soon just abandoned this way.This is because the area that this method can be controlled is too little.The inventor also once tried similarly method before 5 years, but did not obtain fruitful result.
The inventor also learns a kind of device from chilean patents application number NO 682-94, has wherein used a movable machine to blow hot-air, and movable machine is driven by tractor.The grower who has this device has spoken of drawing, but never sees drawing.This grower also speaks of fan blower and says that the angle of attack of blower vane can change.Therefore this is an axial blower obviously, use with the grower in EIOlivar one county and the previous proof fan blower of the inventor be similar.
Along with the development of new irrigation technique, people use the moistening crop of irrigation sprinkler to avoid the injury of frost.But problem is, in some cases, is imperfect with next moistening crop of irrigation sprinkler or fruit tree, because this may cause mycosis, and in winter, people often do not have enough water to use.
The inventor also retrieves in the CAR of Universidad Catolica abstract system, has found the article of 147 pieces relevant " avoiding frost ", and wherein having only two pieces of articles is to control frost with special device.Wherein one piece of what was published in the Republic of Georgia " Tractory-i-sel ' skokho-syainestevernye-Mashing " literary composition and has spoken of a static machine YOP-2 and a movable machine YOP-2M in 1991.Static machine is arranged on the tower, the pipe that this machine is 1 meter rotation with hot-air by a diameter, cover 200 meters radius areas, this device is better than traditional fan blower or propeller, because the frost that traditional fan blower or propeller cause convection current is inoperative.Wherein the machine of Yi Donging is placed on the trailer, and it produces the mist that sprays to the crop sky.This for this reason device per hectare will be used the water of 90-100 metric ton (MT).
The purpose of this utility model be to provide a kind of prevent effectively crops and orchard produce in by device that frost injured.
The device of frost protection during a kind of crops that the utility model provides and orchard produce utilizes centrifugal blower to be inserted into cold air group the inside to one deck hot-air (also being the hot-air bag).This centrifugal blower has two outlets and a heater, centrifugal blower is installed on the tractor, wear with the speed about 10Km per hour that to cross the air that the crop field blows out be not have disturbance, promptly do not breathe heavily stream, therefore a removable very long segment distance also can form a kind of air layer that is referred to as the hot-air bag.This hot-air bag is lower, because its inertia, it can be flow through crops or orchard by the same direction that fan blower blows out.
Temperature when hot-air leaves fan blower is 80 ℃, its very fast and cold air mixing, and therefore after about 2 meters of process, temperature has dropped to about 25 ℃.After arriving 10 meters, temperature no longer is higher than 10 ℃, highly locates at this, and the level of this air is still very high to speed, so its continues to advance along same direction, but it is no longer to rising.When speed descended, the temperature difference of this air and surrounding air also descended.Their density is similar, thereby the air continuation is moved in the horizontal direction and on same height, and this is this device and traditional difference just.Its purport is nothing but that the hot-air of temperature inversion layer is mixed with the cold air that contacts crop.Because the air turbulence that they blow out is very big, so be highly effective to Air mixing.Axial flow blower or propeller as for the grower in chilean patents application 682-904 number and EI Olivas county all do not have practical effect, because the area that can control is too little, can only mixes air and can not form hot air layer (or air bag).
More particularly, the device of frost protection during a kind of crops that the utility model provides and orchard produce, can below natural temperature inversion layer, produce or create the temperature inversion layer of a low clearance artificially, and do not exist under the convection current frost situation of natural temperature inversion layer, can simply create the temperature inversion layer of a low clearance.
