Description

Technical Field

[0001] The utility model relates to the technical field of mandarin orange pruning tools, in particular to a mandarin orange branch and leaf pruning device. Background Art

[0002] Wogan is a late-maturing hybrid citrus variety and a relatively common type of fruit. When planting Wogan, in order to ensure that the nutrients of the Wogan plant can be normally supplied to the fruit part, and also to reduce the nutrient consumption of other branches, it is usually necessary to prune other messy branches. When pruning, corresponding pruning devices are usually used.

[0003] Common pruning devices are generally pruning machines. When using such pruning machines, workers need to hold them in their hands to perform pruning operations. However, since the branches of the mandarin orange are relatively high, when workers use pruning machines to perform pruning operations, the pruning machines are not high enough, so workers need to use corresponding ladders to climb to the corresponding heights to perform pruning operations. Climbing to the corresponding heights is high-altitude work and is very dangerous. There are also some vehicle-type pruning devices, which are large in size. Most of the mandarin oranges are planted in mountains or on land with a certain slope. At this time, vehicle-type pruning devices are difficult to move normally to mountainous areas for pruning operations, which brings inconvenience to users. In view of this, we propose a branch and leaf pruning device for mandarin oranges. Utility Model Content
