Description

A semi-automatic jujube fruit picking and transporting trolley

technical field

The invention relates to the field of mechanical equipment, in particular to a semi-automatic jujube fruit picking and transporting trolley for agricultural fruit picking and harvesting, which is suitable for all kinds of jujube fruits that can be picked by traditional stick percussion or vibration picking methods.

Background technique

my country is a big country producing jujubes, and jujube trees are unique fruit trees in my country. There are 23 million mu of jujube trees in my country, with a yield of 46 billion kilograms, accounting for more than 98% of the world's planting area. Therefore, how to efficiently pick jujube fruits is an important issue in current jujube fruit harvesting, and it is also an important problem that the majority of jujube farmers urgently need to solve. Jujube fruit harvesting mainly adopts the hand picking method, the knocking method and the ethylene drop method. Among them: the hand-picking method is suitable for lower jujube trees, and the fruit that meets the requirements can be accurately harvested according to the needs. The fruit quality is high, but the work efficiency is low; the knocking method is suitable for taller jujube trees. If the jujube is damaged, the jujube can be placed under the tree by using a pole to shake the branches, which will cause great damage to the jujube tree; the fall-inducing method is to use ethephon to accelerate the harvesting, and the effect is good. It is not suitable for some varieties with thin peels. . However, these methods have the defects of high labor intensity, poor protection of jujube fruit, and low picking efficiency, resulting in a corresponding reduction in the economic benefits of fruit farmers.
