Frost is a short-term cold disaster caused by the southward movement of cold air or radiation cooling, which causes the temperature of soil and plant surface and surrounding air layer to drop below 0℃ in a short time, resulting in plant damage or death.orchard fan greatly reduces the agricultural loss so this article introduces structure and characteristics of orchard fan.
The following knowledge points are listed below:
Structure of orchard fan
Characteristics of orchard fan
Frost is one of the agricultural meteorological disasters.As the global climate warms, some of the climatic characteristics of frosts change and the impact of freakish years increases.In recent years, traditional frost prevention methods such as fumigation, irrigation and mulching have good effects on crops, but they are time-consuming and laborious, and some of them are easy to cause environmental pollution.Orchard fan's invention solves this problem. Orchard fan disturbs the air in the near-ground inversion layer to achieve forced convection of cold and warm air at the upper and lower levels, which can effectively raise the temperature of crop canopy and avoid and reduce frost damage.Let's take a look at the structure and characteristics of orchard fan.
Orchard fan arrangement structure, its structure includes: (1), the post adjustment bracket (3) and (1) through the post (2) the adjustable bolt connection, fan motor (4) and fan blade (5) tighten on the adjusting bracket (3), tea fruit (6), the support frame (7), (8) transmission system, set up in an underground electric motor (9), the support frame (7) on the up and down fully the ram (11), (8) through the transmission system connected to the electric motor (9) of the axial flow fan (10), placed in tea tree (6) canopy temperature sensor (12);The adjusting bracket can adjust the Angle between the fan and the horizontal ground;The number of temperature sensors (12) is odd and randomly placed on the fruit tree.Orchard fan startup and shutdown are controlled by an intelligent system and connected to the temperature sensor: orchard fan is enabled when the temperature of half or more of the temperature sensors reaches 2℃.
Orchard fan includes standing orchard fan and suction orchard fan;The vertical orchard fan column and adjusting bracket are fixed by adjustable bolts to adjust the Angle between the fan motor and the horizontal plane;The height of the suction orchard fan air duct is higher than that of the vertical orchard fan.Temperature sensors placed on the canopy of the tea fruit tree are used to directly and accurately identify whether the temperature meets the criteria for orchard fan to be turned on.Three or more vertical orchard fans are arranged around the suction and drainage orchard fans to form a small airflow loop, which can cause the airflow to spiral downward and pressure the airflow to flow rapidly towards the middle, which is convenient for the suction and drainage orchard fan to improve the anti-frost effect, and enables the surrounding orchard fan to form a small airflow rotation.The vertical orchard fan is not boxed to ensure uniform wind speed and increase its service life.The air flow generated by each group of fans rotates in the opposite direction, causing friction in the air, forming convection and raising the temperature.
Orchard fan is a special equipment that USES steel pipes to support fans 6m above the ground. The whole machine is mainly composed of columns, machines, fans, controllers and other auxiliary accessories. The wind direction and Angle can be adjusted to adapt to different terrain.The orchard fan is mostly used in orchards and is designed for water resistance, safety and durability.Compared with the traditional frost prevention measures, orchard fan has an input long-term benefit, a high degree of automation, simple operation, easy to maintain, and advantages of the reduction of labor intensity, and frost prevention effect is good, can effectively solve the use of large conventional frost prevention high equipment cost, transportation, loading and unloading of red tape and artificial expected frost time reliability problems.
