A thermal insulation device for overwintering passion fruit planting

Abstract

The invention discloses a heat preservation device for overwintering planting of passiflora edulia Sims and particularly relates to the field of crop planting equipment. The device comprises a shell, the shell comprises a left shell body and a right shell body, and heat preservation air-returning mechanisms are arranged in the left shell body and the right shell body; hot air mechanisms are arranged at the bottoms of the outer sides of the left shell body and the right shell body, and a PLC is fixedly arranged at the top of the outer side of the right shell body; the heat preservation air-returning mechanisms comprise air cavities. According to the heat preservation device, a motor drives impellers to rotate, air of an external environment is sucked into heating air cavities for heating and is blown to stems of plants of the passiflora edulia Sims through second air outlets for heat preservation, the heating face is even, and the heat preservation effect is good. Meanwhile, the hot air can also enter the first air cavity through an air returning port and is outward blown to branches and leaves of the plants of the passiflora edulia Sims through first air outlets at different angles, invasion of cold air to the branches and leaves of the plants of the passiflora edulia Sims can be effectively reduced, and the branches and leaves are prevented from being damaged due to freezing.

Description

technical field [0001] The invention relates to the field of crop planting equipment, more specifically, the invention relates to a heat preservation device for overwintering passion fruit planting. Background technique [0002] Passion fruit (Passiflora edulia Sims) is a tropical and subtropical vine with strong adaptability and stress resistance, fast growth, few pests and diseases, and various varieties. The temperature requirements of passion fruit are basically the same as those of ordinary tomatoes. It has wide adaptability and is suitable for planting in the north and south. In the north, it is better to survive the winter in a greenhouse. In the south, it is necessary to cover the cold before the frost period above 1400m above sea level, so that it can survive the winter safely, otherwise the upper part of the main stem Most of the branches and side branches were frozen, and even the whole plant was frozen to death. [0003] The invention patent of patent applicatio...

Problems solved by technology

[0004] However, when it is actually used, there are still many disadvantages, such as only the stalk of the passion fruit plant can be kept warm, and its heat preservation effect is poor, and the branches and leaves are also easy to be frozen.
