Embodiment Construction

[0013] specific implementation plan

[0014] refer to figure 1 , this embodiment of the present invention comprises by fan 1 (unloading cast chassis and column that are not utilized for the present invention by electric exhaust fan just), fan seat 2, fan cover 3, suction pipe 4, mast 5, hoisting rope 5a, Pulley 5b; Fan seat 2 is close to the big end of the tapered pipe 20 of a section film system of the periphery of hole neck 2a left and right sides of the bottom respectively, and the small end of tapered pipe 20 is enclosed within the periphery of exhaust ring 21, and tapered pipe 20 inserts length ( The big and small ends) are about 2cm, and the rubber ring A is hooped on the periphery of the insertion part to achieve connection and airtightness. In the same way: the periphery of the other end of the exhaust ring 21 is put on (film system) horizontal tube 22, and the outer end of the horizontal tube 22 is to be enclosed within the periphery of one end of the next joint exha...

Abstract

The invention provides a frost-resistant fan which can be stored and delivered easily. A hoist rope goes around pulleys at a masthead to lift a supporting bamboo which is used for keeping an inhalation tube straight and lift an inhalation opening to the height of 7.7m (far higher than a mast). The lower end of the inhalation tube is connected with a fan shell and a fan base which are arranged on the ground; the fan in the fan base utilizes an electric blower in seasonal idle and removes a cast iron bottom plate and a vertical column which are not adopted by the invention. When a temperature controlled probe detects the temperature in a tea bush is lower than 3.5 DEG C, the fan then starts to run and the inhalation tube sucks the air not less than 5 DEG C from the upper space and transmitsthe air through a transverse tube and an exhaust ring to the tea bush to increase the temperature and blow away frost and coldness. The fan has the advantage that the price of each fan is less than one twentieth of that of an imported fan.

Description

technical field [0001] The invention belongs to the field of anti-frost technology for spring tea, which utilizes the electric exhaust fan for blowing grains or barnyardgrass in summer and autumn, and temporarily changes it to an early-spring anti-frost fan for tea trees during the seasonal idle period; once the frost period is over, the electric exhaust fan is still restored function of the wind. Background technique [0002] On May 30, 2008, Zhejiang Science and Technology News: The project of "Building China's White Tea City in Anji" has been signed; the current output value of Anji tea is 675 million yuan. This shows that the production value of spring tea is very high, and frost protection is very important, so it is indeed a good idea to import frost-proof fans of 20,000 yuan each from Japan. [0003] According to statistics from the Provincial Department of Agriculture, more than one million acres of tea gardens have been damaged by freezing in Zhejiang Province. In...
