Front suspension type jujube tree pruning machine special for jujube tree branch pruning

Abstract

The invention discloses a front suspension type jujube tree pruning machine special for jujube tree branch pruning. The machine comprises a walking mechanism and a pruning device, the pruning device comprises an upper fixing base, a lower fixing base and a pruning mechanism fixing frame, the upper fixing base is connected with an upper connecting base through a hinge base A, and the lower fixing base is connected with a lower connecting base through a hinge base A. Profiling wheels are arranged below the lower fixing base and can rotate, an oil cylinder base is arranged on the upper fixing base or the lower fixing base, a pruning mechanism is arranged on the pruning mechanism fixing frame, the pruning mechanism comprises an annular waistband and a saw blade, a gap is formed in the surfaceof the waistband, the annular waistband and the saw blade are arranged coaxially, and a rotating shaft is arranged on the saw blade. The rotating shaft is driven by a driving mechanism to drive the saw blade to rotate with the rotating shaft as the circle center, branching comb teeth are arranged on the outer surface of the waistband, the branching comb teeth comprise a comb handle and branching teeth, one end of the comb handle is fixed to the outer side of the waistband, and the branching teeth are fixed to the comb handle and symmetrically arranged at the two sides of the gap.

Description

technical field [0001] The invention belongs to the field of garden machinery, and in particular relates to a front-mounted jujube pruning machine for pruning jujube branches. Background technique [0002] "The world's jujubes are in China, and Chinese jujubes are in Xinjiang." China's jujube planting area and output rank first in the world. Jujube is one of the characteristic forest fruits in Xinjiang, and Xinjiang is the largest high-quality jujube planting base in China. According to the latest statistical yearbook of Xinjiang and XPCC, in 2017, the planting area of ​​jujube in Xinjiang was 7.144 million mu, with an output of 3.47 million tons, of which 1.613 million mu of XPCC, with an output of 1.82 million tons. The output of red dates in southern Xinjiang accounts for about 97% of the total output in Xinjiang, so the red date industry is an important pillar industry for the agricultural development of southern Xinjiang. [0003] Dwarf dense planting trunk shape is c...

AI Technical Summary

Problems solved by technology

Traditional manual pruning is time-consuming, laborious, and inefficient, and cannot meet the production requirements of large-scale planting of jujubes. Moreover, the problem of high production costs due to labor shortages has become increasingly prominent. The economic benefits of jujubes have continued to decline. It is urgent to develop jujube pruning machinery and equipment to replace humans. job

[0004] Due to the high density and high hardness of jujube branches, the existing fruit tree pruning machines (reciprocating type, rotary knife type) are mainly suitable for fruit tree pruning operations such as grapes, and it is difficult to meet the requirements of jujube tree pruning. The current pruning machine is not suitable for jujube trees. The pruning of tree branch, main problem is: the one, can not effectively cut off branch (cutting constantly and easily pull damage), the 2nd, can not realize three-dimensional profiling layered pruning of crown,

With the rapid development of standardization, scale and industrialization of new jujube orchards, it is imperative to mechanize the entire process of jujube orchard management. Manual pruning and existing pruning equipment can no longer meet the pruning technical requirements of standardized garden construction, and there is an urgent need for efficient, versatile and Huagao pruning equipment replaces traditional work tools
