Special climbing ladder for nut picking

Abstract

The invention provides a special climbing ladder for nut picking. The special climbing ladder is characterized by comprising a main supporting frame, wherein an auxiliary supporting frame is assembledto the top of the main supporting frame; the main supporting frame and the auxiliary supporting frame adopt cylindrical structures; the pore diameter of the auxiliary supporting frame is greater thanthat of the main supporting frame; spacing holes are formed in the surfaces of the main supporting frame and auxiliary supporting frame; a pedal is arranged in the spacing hole; the spacing hole andthe pedal adopt rectangular structures; a base is arranged at the bottom of the main supporting frame; a bottom plate is arranged at the tail end of the base; a plurality of groups of fixed pieces aredownward vertically arranged at the bottom of the bottom plate; a tension piece is arranged between the bottom plate and the base. The special climbing ladder can meet the requirements on different heights when nuts, such as Chinese torreya, pecans and Chinese chestnuts, are picked through the assembly of the main supporting frame and the auxiliary supporting frame according to variable landforms, such as mountains and sloping lands, in which nut trees mainly grow, is simple in design structure and convenient to carry and dismount, can effectively enhance the self stability and firmness through a single column structure, guarantees the picking safety, and deserves promotion.

Description

technical field [0001] The invention belongs to the technical field of forestry, in particular to a special climbing ladder suitable for picking nuts. Background technique [0002] Nuts are popular as a high-value food, and the planting of nut trees is becoming more and more common. However, in many cases, the picking of nuts needs to be done manually. Torreya trees are mainly distributed in mountainous areas such as Mount Huangshan, Wuyi Mountain, and Huiji Mountain in my country. In order to pick the fruits of the Torreya tree, it is necessary to climb and pick them with the help of a ladder. Because the Torreya tree grows in mountainous areas, the ground is rough, and the trunk of the Torreya tree is high and straight. It is difficult for the existing parallel double-column climbing ladder to reach the height of the fruit-bearing tree canopy, and it is difficult to fix the ladder in the nut forest, it is easy to tilt, and the stability is poor, which leads to potential safe...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the shortcomings of the existing ladders, such as many stress points, unsuitability for handling in mountainous areas and forests, poor stability, and insufficient height, which cannot meet the needs of nut picking, the present invention designs a special climbing ladder, which can realize the operation of ladders in mountainous areas with varied terrains. Fixed, and at the same time meet the needs of climbing. In order to adapt to the height of nut trees, the ladder of the present invention can be assembled at different heights. It is simple and convenient to operate and has strong practicability. It solves the problem of fixing the ladder in mountainous terrain and at the same time ensures the safety of the picking process , the specific plan is as follows:
