Description

Self-propelled layering jujube tree trimming machine

Technical Field

The utility model belongs to the garden machine field, concretely relates to front suspension type jujube tree trimming machine for pruning jujube tree branch.

Background

"world red date is in China, and Chinese red date sees Xinjiang". The planting area and the yield of Chinese red dates are the first in the world, the red dates serve as one of special Xinjiang forest fruits, and Xinjiang is the largest high-quality red date planting base in China. According to the latest new year book of Xinjiang and military grouping statistics, the method comprises the following steps: the planting area of Xinjiang red dates in 2017 is 714.4 ten thousand mu, the yield is 347 ten thousand tons, the army is 161.3 ten thousand mu, and the yield is 182 ten thousand tons. The yield of the southern Xinjiang red dates accounts for about 97% of the total yield of the whole Xinjiang, so the red date industry is an important support industry for the development of southern Xinjiang agriculture.

The dwarf dense planting trunk shape is the current planting mode of main pushing of the war group red dates. The pruning of the jujube trees is a key link of the standardized management of the jujube garden, and the seasonality is strong. Traditional artifical pruning wastes time and energy, inefficiency, can not satisfy the production requirement that the red date scale was planted, moreover because the problem that the labour is in short supply and leads to manufacturing cost to be high is outstanding day by day, red date economic benefits continuously descends, awaits urgently to research and develop the pruning mechanical equipment of jujube garden and replace manual work.

Because the texture density of red date branch is high, hardness is big, current fruit tree trimming machine (reciprocating type, rotary knife formula) mainly is applicable to fruit tree pruning such as grape and prunes the operation, is difficult to satisfy the requirement of jujube tree pruning, and present trimming machine is not applicable to the pruning of jujube branch, and the main problem lies in: firstly, the branch can not be effectively cut off (the branch is continuously easy to pull and damage), and secondly, the tree crown three-dimensional profiling layered pruning can not be realized.

Aiming at the whole-course operation machine tool of the red dates, no mature machine tool can be introduced and imitated abroad, relevant machines for harvesting, spraying, fertilizing and the like of the red dates are trial-produced in relevant colleges and universities and research units at home, but the relevant research on the mechanical trimming of the red dates is less. With the rapid development of standardization, scale and industrialization of a newly-built jujube garden, the whole-course mechanical management of the jujube garden is imperative, manual pruning and the existing pruning equipment cannot meet the technical requirements of the standardized garden building, and efficient, universal and high-degree pruning equipment is urgently needed to replace the traditional operation equipment.

Therefore, there is a need in the market for a self-propelled layered jujube tree trimmer that can be applied to pruning jujube trees.
