Frost prevention equipment for teaching

Abstract

The invention discloses frost prevention equipment for teaching. The frost prevention equipment comprises a box body, temperature sensors, flues, a cigarette lighter, a controller and a battery, wherein the four temperature sensors are provided, are respectively located at corners above the box body and are located in a protective cover; the two flues are provided, are located above the box body and are communicated with a combustion chamber in the box body; the cigarette lighter is located inside the box body and is respectively connected with the controller and the battery which are locatedin the box body; the controller is connected with the temperature sensors and is powered by the battery; the bottom of the box body is further provided with four bases; and two sides of the box body are further provided with handles. The frost prevention equipment is reasonable in design, simple in structure and use and capable of effectively reducing the phenomenon that crops are destroyed by frosts; and the cigarette lighter is reasonably adopted to light a smoke formation material and generate smoke by which the temperature above a farmland or a planting greenhouse is increased and frost injury is avoided, so that the planted plants are protected.

Description

technical field [0001] The invention relates to an equipment for protecting crops, in particular to an anti-frost equipment for teaching. Background technique [0002] With the development of society and the improvement of living standards, people can eat summer vegetables in winter, and vegetables in any season in summer. Most of these crops are cultivated in greenhouses, but in winter Whether planting crops in greenhouses or in farmland, there may be frost disasters. In the traditional way in rural areas, igniting smoking materials (such as dried wheat straw or straw, etc.) is often used to form smoke above the crops through the smoking materials. Layer, through the smoke layer to protect the crops, which can reduce the frost disaster caused by the crops, and can also kill insects through the smoke; but this traditionally requires manual ignition of the smoke material, and the need to manually judge the air temperature, which cannot be done Real-time monitoring, if the ma...

AI Technical Summary

Problems solved by technology

[0003] Therefore, in order to solve the deficiency of the above-mentioned manual smoking material, the present invention provides a kind of reasonable design, simple structure, easy to use, and can effectively reduce the phenomenon that crops are damaged by frost. The smoky material is ignited and produces smoke. Through the smoke, the temperature above the farmland or the greenhouse can be increased to prevent frost damage and protect the plants so that they can still thrive in frosty weather without being damaged by frost.
