Description

Technical Field

[0001] The invention belongs to the field of garden machinery, and in particular relates to a front-suspended jujube tree pruning machine for pruning jujube tree branches. Background Art

[0002] "The world's red dates are in China, and China's red dates are in Xinjiang." China's red date planting area and output rank first in the world. Red dates are one of Xinjiang's specialty fruits, and Xinjiang is China's largest high-quality red date planting base.

[0003] The dwarfing and densely planted trunk shape is the main planting model for jujube in the Corps. Jujube tree pruning is a key link in the standardized management of jujube orchards, and it is highly seasonal. Traditional manual pruning is time-consuming, labor-intensive, and inefficient, and cannot meet the production requirements of large-scale jujube planting. In addition, the problem of high production costs due to labor shortage is becoming increasingly prominent, and the economic benefits of jujube continue to decline. It is urgent to develop mechanical equipment for jujube orchard pruning to replace manual work.

[0004] Due to the high density and hardness of jujube branches, existing fruit tree pruning machines (reciprocating and rotary types) are mainly suitable for pruning grape and other fruit trees, and are difficult to meet the requirements of pruning jujube trees. Current pruning machines are not suitable for pruning jujube branches. The main problems are: first, the branches cannot be effectively cut off (if they are not cut off, they are easily pulled and damaged); second, the three-dimensional contouring and layered pruning of the crown cannot be achieved.

[0005] There are no mature machines for the whole process of jujube operation in foreign countries that can be introduced and imitated. Domestic universities and scientific research institutions have studied and trial-produced machines for jujube harvesting, spraying and fertilizing, but there are few studies on mechanized pruning of jujube. With the rapid development of standardization, scale and industrialization of newly built jujube orchards, the whole process of mechanized management of jujube orchards is imperative. Manual pruning and existing pruning equipment can no longer meet the pruning technology requirements of standardized orchard construction. Efficient, universal and highly chemical pruning equipment is urgently needed to replace traditional operation machines.

[0006] Therefore, there is an urgent need on the market for a hanging type jujube tree pruning machine that is specialized in pruning jujube tree branches before being applicable to jujube tree pruning. Summary of the invention
