Description

Technical Field

[0001] The utility model relates to the technical field of agricultural hole digging, in particular to an agricultural hole digging device with a function of adjusting depth. Background Technique

[0002] The hole digging technology has a long history in agriculture. In the early days, people dug holes with tools such as shovels. With the development of technology, hole diggers have gradually been applied to agriculture, especially in the planting of horticultural crops such as fruit trees, vegetables, and flowers. Agricultural hole digging technology is mainly divided into two categories: manual and mechanical. Manual hole diggers are more common and are suitable for small-scale or complex terrains. Mechanical hole diggers, on the other hand, have higher production efficiency and operation quality and are widely used in large-scale planting and agricultural mechanization operations. Agricultural hole digging technology is an important part of agricultural mechanization. In recent years, by optimizing the structure and function of hole diggers to improve their production efficiency and operation quality, the hole digging technology has also been continuously innovated and improved, playing an important role in promoting agricultural modernization and improving agricultural production efficiency.
