Technical Field

[0001] The utility model relates to the technical field of agricultural tools, in particular to a novel ladder. Background Art

[0002] Fruit trees refer to trees with edible fruits, and are a general term for perennial plants and their rootstocks that can provide edible fruits and seeds, such as apple trees, pear trees, citrus trees, apricot trees, peach trees, etc. In order to increase economic income, planting fruit trees has become an effective way for farmers to increase their income. At present, fruit trees are generally planted in mountainous areas. The fruits on the fruit trees need to be picked after they are ripe. Due to cost reasons, manual picking is the most commonly used method.

[0003] At present, the special picking ladder adopts a tripod structure design, and does not need to be set up during picking. However, the support rod of the existing picking ladder is connected to the climbing frame by thin wire binding, and can only be placed at a maximum angle. Not only is the connection strength insufficient, but the height of the picking ladder cannot be positioned. At present, when pruning or picking fruits on pyramid-shaped trees, in most cases, manual ladders are required for auxiliary operations. However, most of the existing ladders are herringbone ladders. Due to the large number of branches and trunks of the tree, this herringbone ladder cannot be placed inside the tree and can only be placed around the crown of the tree, resulting in a small range of manual pruning or picking. At the same time, since the middle part of the crown of the pyramid-shaped tree is higher and farther away from the periphery, it is difficult to manually prune or pick fruits in the middle part of the crown using the existing ladder.
