Description

Technical Field

[0001] The present invention relates to the technical field of agricultural planting, in particular to a soil loosening device for greenhouse planting. Background Art

[0002] Greenhouses are facilities used for cultivating plants, allowing light to pass through and retaining heat. They provide a growth period and increase yields during seasons unsuitable for plant growth. They are often used for cultivating or raising seedlings of warm-loving vegetables, flowers, and trees during cooler months. Greenhouses provide optimal growth regulation for crops, allowing for multiple harvests per year; multiple harvests also require multiple plantings. Steel pipe support frames are installed within greenhouses to support the greenhouse and provide support for crops, allowing them to grow in a defined pattern.

[0003] Through searching, Chinese patent announcement No. CN117044445B discloses a soil loosening device for greenhouse planting, comprising a vehicle body, a conveyor belt being provided on the upper surface of the vehicle plate of the vehicle body, one end of the conveyor belt being located at one end position of the vehicle plate, the other end of the conveyor belt being located at the other end position of the vehicle plate, and a rotary digging unit being provided at one end position of the vehicle plate; the rotary digging unit comprises 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 to a cross plate, a rectangular hole is provided in the middle of the cross plate, the clearance in the rectangular hole fits 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 to a connecting plate; the setting of the rotary digging unit can be used for rotary digging and loosening soil at a specified position in the greenhouse, and there is no need to loosen the soil for the entire greenhouse. 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] The following defects are found in the above-mentioned related technologies:

[0005] 1. When loosening the soil, it is impossible to selectively avoid the route of buried pipes, which can easily damage the irrigation pipes buried under the soil layer.
