Description

Technical Field

[0001] The utility model relates to the technical field of fruit tree pruning, in particular to a pruning device which is convenient for pruning fruit trees at high places. Background Art

[0002] Fruit tree pruning plays an important role in improving light energy utilization, balancing growth and fruiting, controlling crown size, cultivating tree shape, preventing diseases and pests, and promoting flower bud differentiation. It is an indispensable technical measure in fruit tree management. Nowadays, most pruning is done with pruning shears. For higher positions, most pruning equipment still uses pruning shears as the head. After searching, an apple tree pruning device with publication number CN217790470U and a handheld fruit tree pruning machine with publication number CN113348893B, and an orchard pruning tool with publication number CN209268097U all use pruning shears as the head. The present invention relates to a pruning shears. However, this type of pruning requires a shearing operation similar to that of scissors every time, which is sometimes cumbersome to operate, especially for pruning at higher positions, where positioning is difficult to align. For this reason, a pruning device with both sickle and scissors modes is designed. The sickle can be used to quickly hook the branches of the fruit trees that need to be pruned at a high position and locate the length. When the hardness of the fruit tree branches is moderate, the sickle can be used to cut them directly. When the branches are soft or hard, the scissors mode can be used for pruning and shearing. The pruning device is flexible and easy to operate, has high pruning accuracy, and is convenient for pruning fruit trees at high positions. Utility Model Content

[0013] The pruning device is convenient for pruning fruit trees at high places. Through the long pole, the U-shaped seat and the sickle, the fruit tree branches that need to be pruned at high places can be quickly hooked by the sickle. When the hardness of the fruit tree branches is moderate, the fruit tree branches can be directly pruned down by pulling and rubbing the long pole. When the hardness of the fruit tree branches is relatively soft or relatively hard, the shearing drive mechanism is started to drive the cutter hidden in the U-shaped seat to rotate out, and the cutter is rotated out from the bottom to cooperate with the sickle to shear the fruit tree branches. The pruning device is convenient for pruning fruit trees at high places and has both sickle and scissors dual modes for pruning. The fruit tree branches that need to be pruned at high places can be quickly hooked by the sickle and the length can be positioned. When the hardness of the fruit tree branches is moderate, the branches can be directly cut down by the sickle.
