Description

Technical Field

[0001] This utility model relates to the field of ornamental tree planting, and in particular to a soil screening device for ornamental tree planting. Background Technology

[0002] Ornamental trees refer to all woody plants that can be appreciated for their beauty, including various trees, shrubs, woody vines, and bamboo. It is not a single species, but a general term for trees that have ornamental value. In the process of planting ornamental trees, soil quality directly affects the survival rate and growth status of the trees. High-quality planting soil needs to have good aeration, drainage, and nutrient balance. Natural soil often contains impurities such as stones, root debris, and construction waste. If unscreened soil is used directly, it can easily lead to poor root development, poor drainage, or the breeding of pests and diseases, thereby affecting the ornamental effect and the overall quality of the garden landscape.

[0003] According to Chinese Patent No. CN209034455U, a soil screening device for planting golden fruit ornamental trees includes a base with universal wheels welded to all four corners, an "L"-shaped support rod welded to one side of the top of the base, an installation opening at the center of the top of the base, and bearings welded to the inner wall of the installation opening and the end of the support rod away from the base. A can with an opening at the top is sleeved inside the two bearings, and a top cover is snapped onto the top of the can. Although the above patent solution includes a metal mesh box that is easy to remove, the metal mesh box contains a connecting rod and a breaker hammer. Each time the metal mesh box is removed, the breaker hammer needs to be disassembled first, which makes removal inconvenient. Therefore, we propose a soil screening device for planting ornamental trees to solve the above problems. Utility Model Content
