Cold region fruit tree winter protection equipment

Abstract

The invention discloses cold region fruit tree winter protection equipment which comprises two arc-shaped plates, fixing structures are arranged on the two sides of the outer surfaces of the two arc-shaped plates, the opposite faces of the two arc-shaped plates are in lap joint, and five arc-shaped shells are arranged on the upper surfaces of the two arc-shaped plates. According to the scheme, the automatic air supply device is arranged, in the high-temperature environment and the low-temperature environment, the device can control the controller according to the principle of thermal expansion and cold contraction, then the fan and the heating piece are controlled to operate through the controller in the low-temperature environment, air at the air inlet can be heated through the heating piece, and the temperature of the air at the air inlet can be increased; the hot air is sprayed out by the fan through the air outlet head, so that the fruit tree can be protected, the device stops operating in a high-temperature environment, and the device can realize autonomous control operation by adopting the principle of thermal expansion and cold contraction, so that the device has higher application value.

Description

technical field [0001] The invention relates to the technical field of agriculture, more particularly, to a winter protection device for fruit trees in cold regions. Background technique [0002] Fruit trees in cold regions, also known as fruit trees in cold regions, are a class of fruit trees native to and mainly distributed in cold temperate regions. They are generally deciduous, such as small apples, autumn pears, hawthorns, etc. Most of the fruit trees in cold regions have a trunk diameter of no more than 20 cm within 20 years. cm, after entering the winter, the fruit branches and leaves fall, the trunk will be exposed to direct sunlight, the temperature difference between day and night is large, the fruit tree itself cannot adapt quickly, which will affect the growth of the fruit tree. [0003] At present, in the prior art, in order to reduce the adverse effect of low temperature on the trunk, the surface of the trunk is generally wrapped with thermal insulation cotton ...

AI Technical Summary

Problems solved by technology

[0002] Cold region fruit trees are also called frigid region fruit trees, a type of fruit trees native to and mainly distributed in cold temperate regions, generally deciduous, such as small apples, autumn pears, hawthorns, etc. , and the trunk diameter of most fruit trees in cold regions does not exceed 20 cm within 20 years. After entering winter, the branches and leaves of the fruit trees will fall, the trunk will be exposed to direct sunlight, and the temperature difference between day and night is large. growth

[0003] At present, in order to reduce the adverse effects of low temperature on the trunk in the prior art, it is generally used to wrap insulation cotton and straw rope on the surface of the trunk to keep it warm , but in actual use, it is not only labor-intensive to wind and dismantle, but also cannot be reused, resulting in a waste of resources. At the same time, it can only passively protect the trunk. When the weather is hot, it is difficult to ventilate the fruit trees. When the temperature is extremely low, it can't play a good protective effect, and when the wind is strong, it can't support the trunk stably, making the overall protective effect poor. Therefore, a new winter protective equipment for fruit trees in cold regions is studied. To solve the above problems is of great significance to the protection of fruit trees in cold regions
