[0002] Greenhouses are facilities that can transmit light and keep warm, and are used to grow plants. In seasons that are not suitable for plant growth, they can provide a greenhouse growth period and increase production. They are mostly used for the cultivation or seedling raising of warm-loving vegetables, flowers, trees and other plants in low-temperature seasons. Greenhouses can provide good growth regulation for crops, so that crops can be harvested more often in a year; multiple harvests mean multiple plantings; a steel pipe support frame is set up in the greenhouse to support the greenhouse or provide support for crops, allowing them to grow in a certain direction.

[0003] Through searching, Chinese patent announcement No. CN117044445B discloses a soil loosening device for greenhouse planting, including a vehicle body, a conveyor belt is provided on the upper surface of the vehicle plate of the vehicle body, one end of the conveyor belt is located at one end of the vehicle plate, the other end of the conveyor belt is located at the other end of the vehicle plate, and a rotary digging unit is provided at one end of the vehicle plate; the rotary digging unit includes two No. 1 electric push rods and one No. 2 electric push rod; the No. 1 electric push rod is symmetrically fixedly arranged on the vehicle plate, the lower end of the cylinder body of the No. 1 electric push rod is fixedly connected with a cross plate, a rectangular hole is provided in the middle of the cross plate, the clearance in the rectangular hole matches the outer surface of the cylinder body of the No. 2 electric push rod, and the lower end of the cylinder body of the No. 2 electric push rod is fixedly connected with a connecting plate; the setting of the rotary digging unit can be used for rotary digging and loosening soil at a specified position of the greenhouse, and there is no need to loosen the soil of the entire greenhouse as a whole. At the same time, the soil loosening device provided in this embodiment can adapt to the corner positions with limited space due to the structural setting, and can be flexibly moved to each position in the greenhouse.

[0004] With respect to the above-mentioned related technologies, the following defects are found:
