Description

Technical Field

[0001] The invention relates to the technical field of garden planting, and in particular to a garden planting pit digging device and a pit digging method thereof. Background Art

[0002] Landscape greening includes: gardens, urban greening, scenic spots and landscaping, and garden trees are more commonly used in garden and forest greening. Garden trees are usually woody plants suitable for planting and application in urban gardens and scenic areas, including various trees, shrubs and vines. Planting garden trees first requires digging holes in the land. Usually, digging holes is done manually. The labor intensity of workers digging holes is high and the labor efficiency is very low, so it has been gradually eliminated. Subsequently, many mechanical digging devices were introduced, such as directly using excavators to dig holes. However, due to terrain restrictions and requirements for the size and shape of the pits, the shape of the pit can be round or square, but the pit wall should be vertically downward to avoid digging into a pot-bottom shape that is large on the top and small on the bottom. Therefore, it often cannot meet the operation requirements and requires subsequent manual repairs.

[0003] A landscaping digging device with application number 202211676594.9 and a method of using the same include: a frame, a digging barrel slidably connected to the frame, an electric push rod fixedly connected to an inner wall of one side of the frame, and an output shaft of the electric push rod fixedly connected to the digging barrel, a digging structure arranged in the digging barrel for automatically performing digging operations, and a planting structure arranged in the frame for automatically completing the planting of seedlings.

[0004] A digging device for landscaping planting with application number 202221540312.8 includes a mobile body, a gear column is fixedly connected to the mobile body, and a lifting plate is slidably provided on the outside of the mobile body, a prismatic sleeve is fixedly connected to the bottom surface of the lifting plate, a lifting slide is slidably provided in the prism sleeve, a transmission shaft is rotatably provided in the lifting slide, and a plurality of rotating parts are rotatably connected to one end of the prism sleeve.

[0005] However, pit digging and planting often requires steps such as digging holes, taking soil, planting, and filling holes.
