Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of landscaping, in particular to a pruning machine for landscaping. BACKGROUND

[0002] Landscaping is a beautiful natural environment created by engineering technology and artistic means in a certain region, through landform modification including mountain building, rock stacking, rock arrangement, tree and plant planting, building construction, and garden road arrangement.

[0003] The growth rate of plants is different in different seasons, and they are prone to horizontal growth, which can affect pedestrian passage. When pruning is needed, the existing pruning machine can only prune thin branches, and tools are needed to prune thick branches.

[0004] In order to overcome the above defects, the prior art (application number: CN118402394A, application date: March 6, 2023, Chinese patent) discloses a rear suspension type pruning machine. The invention provides a rear suspension type pruning machine, which comprises a mounting frame, a clamping assembly, a lifting assembly, a servo motor, a saw blade and a jacking assembly, etc. The mounting frame is provided with a clamping assembly for clamping branches. The mounting frame is provided with a lifting assembly. The lifting assembly is provided with a servo motor to control the lifting of the servo motor. The saw blade is connected to the output shaft of the servo motor through a coupling to drive the saw blade to rotate. When the saw blade moves upward with the servo motor, it can cut the branches. The jacking assembly is used to lift the end of the branch. The clamping assembly of the invention can clamp the branches to be cut, and then the saw blade can cut the branches. No manual high-altitude operation is required, which can improve safety. When the end of the branch droops, the second electric push rod can drive the jack rod to move upward to slightly lift the branch, preventing the saw blade from being stuck in the branch.

[0005] Although the prior art can solve the above problems, the height adjustment design for different pruning requirements is too complex. When facing plants of different heights, the pruning height needs to be different. The prior art cannot well adjust the height, which affects the pruning efficiency. Moreover, the cleaning design after cutting is lacking. The surface of the branch is covered with smaller branches, leaves and even vines. If not cleaned in time, it may cause the machine to jam and not work normally. INVENTION CONTENTS
