High-speed water jet type high-altitude nursery stock pruning device

Abstract

The invention relates to a high-speed water jet type high-altitude nursery stock pruning device. The high-speed water jet type high-altitude nursery stock pruning device comprises a high-pressure water source pump, a conveying pipeline and a spray head, the spray head is fixed in a spray nozzle fixing hole of a positioning ring, the positioning ring is fixed to the upper end surface of an upper buckling circular ring to form a water cutting type annular cutting mechanism, the upper buckling circular ring and a lower buckling circular ring are utilized to form a crawling and rotating device, afirst telescopic device, a second telescopic device and a third telescopic device are arranged between the upper semicircular rings and the lower semicircular rings of the upper buckling circular ringand the lower buckling circular ring, a first crawling wheel is arranged at the tail end of the first telescopic device, a second crawling wheel is arranged at the tail end of the second telescopic device, rolling wheels are arranged on the opening sides of the upper buckling circular ring and the lower buckling circular ring, and a steering wheel is arranged at the tail end of the third telescopic device.

Description

technical field [0001] The invention relates to the technical field of high-altitude seedling pruning devices, in particular to a high-altitude seedling pruning device for high-speed water jetting. Background technique [0002] At present, in terms of tree pruning, it mainly relies on manual pruning, which is carried out by means of chain saws, knives, and axes. It requires the use of ropes, escalators, and even cranes. The operation cost of the above method is high, and the pruning precision is poor. The operation habit of pruning seedlings only needs to be pruned. Generally, the branches below the top of the seedlings are pruned. As the tree grows taller, it is necessary to remove the head and non-main branches in the mobile load value to ensure the survival rate of the mobile. In order to reduce the damage to the roots, it is necessary to excavate the roots with soil, but if the seedlings are not pruned, it is easy to produce heads. Heavy, resulting in insufficient suppo...

[0002] At present, in terms of tree pruning, it mainly relies on manual pruning, which is carried out by means of chain saws, knives, and axes. It requires the use of ropes, escalators, and even cranes. The operation cost of the above method is high, and the pruning precision is poor. The operation habit of pruning seedlings only needs to be pruned. Generally, the branches below the top of the seedlings are pruned. As the tree grows taller, it is necessary to remove the head and non-main branches in the mobile load value to ensure the survival rate of the mobile. In order to reduce the damage to the roots, it is necessary to excavate the roots with soil, but if the seedlings are not pruned, it is easy to produce heads. Heavy, resulting in insufficient support, prone to root breakage, damage to the roots and a decrease in survival rate, so a high-altitude seedling pruning device suitable for high-speed water injection of vertical seedlings is needed
