Plant assisting anti-frost device

Abstract

The invention discloses a plant assisting anti-frost device which comprises a stand column and a rotary shaft on the top of the stand column. The rotary shaft is connected with an axial flow draught fan through a swing rod hinged to the rotary shaft. A gear box, a motor and a gear box motor output shaft are further arranged on the top of the stand column. The gear box motor output shaft is connected to an upper obtaining power source in the gear box. The gear box motor output shaft is movably connected with the rotary shaft through a transmission shaft. The bottom of the stand column is connected with a lifting device. The lifting device comprises a lifting motor, a motor shaft and a worm. One end of the motor shaft is connected to the output end of the lifting motor. The other end of the motor shaft is connected with the worm. The bottom of the rotary shaft is connected with a lifting shaft core. The bottom of the lifting shaft core is provided with a lifting cam. The lifting cam and the worm are matched and rotate. By means of the plant assisting anti-frost device, the blind area of the anti-frost device is compensated for, the use efficiency of the plant anti-frost system is further improved, and the growth state, the survival rate and quality of plants are increased.

Description

technical field [0001] The invention relates to the technical field of plant frost protection, in particular to an auxiliary plant frost protection device. Background technique [0002] The growth of plants requires a balanced supply of sunlight, water, soil and other climatic conditions. Especially for the growth of tea trees, the requirements for climate are relatively high. When encountering frosty weather, a large number of tea trees will be frozen to death and it is difficult to survive. With the development of agricultural science and technology, a special intelligent anti-frost system equipment has been developed to treat tea trees with anti-frost treatment. For this kind of equipment, refer to the authorized patent, CN201310288428-a fan system control method for preventing plant frost damage And device and CN101322466B a kind of fan system control method and device for preventing plant frost damage, above-mentioned two patents have disclosed the system structure of a...

Problems solved by technology

The temperature rise effect on the canopy and 3m above it is greater than that at 2m, but frost damage still occurs within 5m in front of the wind turbine. The main reason is that the wind turbine is installed at a high altitude, and there is a large pitch angle, resulting in no air flow in this range Disturbance, so that the cold air in the canopy cannot mix and heat up with the air flow of higher air temperature above
