Description
Technical field
The utility model relates to a kind of crops frost damage protection-gear, especially can prevent and kill off the air duct device of tea, fruit tree cold in the late spring Spring frost.
Background technology
Production brings serious harm to the Spring frost in early spring to agriculture and forestry plant, particularly enormous economic loss is caused in tea place and orchard.Under early spring inversion condition, in continuous heavenwards radiation in night, cause near-earth temperature to descend fast because plant absorbs a large amount of solar radiations daytime this moment, forms the low temperature inversion of relative superiority or inferiority on the air themperature field often in the generation of Spring frost.The cold air of near-earth constantly deposits at the more low-lying place of landform, causes freeze injury further to aggravate.And tea tree and fruit tree cold resistance the poorest opportunity (as bud-leaf sprouting period or florescence) be at a time when the late frost period happening with increasing frequency, and freeze injury directly threatens its g and D, thereby influences output, quality or listing phase.
Traditional sootiness or method such as pour water, antifrost effect is poor, also can cause environmental pollution; Application number is the frost prevention method that 200610135267.7,200510051371.3 and 87106933.4 Chinese patent discloses spraying respectively and covered, but its operation wastes time and energy, and labor productivity is low; Grant number is 99242734.7 utility model, then discloses the demisler by fuel Heating, and obviously its cost is higher, and the labour intensity of night time operation is big.
The method and apparatus of external mechanization frost prevention, the temperature field characteristic distributions of inversion when all making full use of into frost by machinery (as blower fan) disturbance near-earth temperature inversion layer air, imports the below plant canopy with the top high temperature air, effectively improve its temperature, avoid or alleviate frost damage.The patent No. is the United States Patent (USP) of US5244346 and US4501089, discloses respectively to utilize axial flow blower or subsidiary centrifugal blower that the top warm air is blowed to the device of below, is used to prevent and kill off fruit tree and oenin freeze injury.The patent No. is the Japan Patent of JP2007000096, JP2000050749 and JP10113076, then discloses the overhead fan that is used for Japanese tea place and orchard frost prevention.External frost prevention cost of goods manufactured is all higher.At home, grant number is 200810124434.7 patent of invention, discloses a kind of method for controlling fan system and device of preventing frost damage of plant; Grant number is 200810061122.6 patent of invention, discloses a kind of fresh tea anti-frost fan.But being still by overhead fan, its core technology carries out frost prevention.More than domestic and international mechanization frost prevention method and apparatus, cost is higher, and is not easy to installation and maintenance, so large-scale promotion application is limited.Overhead in addition fan frost prevention owing to its structural characteristics, the blind area of frost prevention inevitably can occur.
Summary of the invention
Above prior art antifrost effect is poor in order to overcome, cost height, installation and maintenance inconvenience, problems such as blind area occur, and the utility model provides a kind of novel suction-discharge type frost prevention air duct device.It is installed on the ground in tea place or orchard, is convenient to operation and maintenance, and the frost prevention area is big, and the cost of unit frost prevention area is low.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of tea fruit garden is made up of axial flow blower, air duct, electromotor, transmission system and bracing frame with suction-discharge type frost protection air duct, axial flow blower links to each other with electromotor by transmission system, the axial flow blower outside is provided with penetrating air duct up and down, the top opening of air duct is an exhaust outlet, lower opening is an air guide hole, and air duct and axial flow blower are separately fixed on the bracing frame.Axial flow blower is parallel to ground and is installed in the air draft tube, is connected to by transmission system on the output shaft of electromotor; The air duct lower edge apart from ground level greater than 0.4 meter.Air duct is by regulating bolt on bracing frame, and the distance of air duct distance bracket bottom can be by regulating the bolt adjustment.
During use the frost prevention air duct is installed on hypsography low-lying place in the tea fruit garden, or is installed on and flatly goes up, and periphery is aided with shelter forest or artificial air partition,, improve antifrost effect to prevent that cold air constantly flows at a distance.
The beneficial effect that the utility model had is: by axial flow blower disturbance air, to the top, tea place, stop temperature to continue to reduce the air suction of near-earth Cryogenic air layer, and then alleviate or prevent frost.Its manufacturing cost and use cost is lower, only is 1/5 of traditional overhead frost prevention fan; Be installed on the ground easy to use and maintenance; Have bigger frost prevention area than overhead fan, cut the blind area of having avoided overhead fan frost prevention to occur.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a frost prevention technical schematic diagram of the present utility model.Wherein, 1 is that axial flow blower, 2 is that air duct, 21 is that exhaust outlet, 3 is that air guide hole, 4 is that electromotor, 5 is that transmission system, 6 is that bracing frame, 7 is that air partition, 8 is that tea fruit is set.
