Description

Technical Field

[0001] The utility model relates to a digging device, in particular to a digging device used for agricultural planting. Background Art

[0002] In the process of agricultural planting, shovels are often used to turn the soil or dig holes. When digging, the shovel is pressed down into the soil with the foot, and then the soil and the shovel are lifted up using the arm strength and waist strength to achieve the purpose of digging. However, the disadvantage of this structure is that when turning the soil upward, the human body is used as a fulcrum and the arm is used as a lever. The arm strength and waist strength are applied to turn the soil up, which requires the whole body to exert strength, the labor intensity is high, and the arms and waist bear greater force. These two parts feel more tired and are prone to injury. Utility Model Content
