[0002] A greenhouse is a constant temperature protection structure for growing vegetables or fruits. It is mainly composed of a steel frame structure and a protective film on the outside. People can grow vegetables and fruits of all seasons in a greenhouse to meet people's needs for off-season fruits and vegetables in different seasons, especially in winter. With the rapid development of modern agriculture, greenhouses have become an important part of efficient agriculture. In order to efficiently spray water, spray pesticides or transport crops in the greenhouse, tracks are usually set up in the greenhouse for the trolley to travel and provide convenience.
