Mechanical auxiliary negative pressure collecting jujube leaf separation automatic jujube-picking machine

Abstract

The invention discloses a mechanical auxiliary negative pressure collecting jujube leaf separation automatic jujube-picking machine. The machine comprises a mechanical arm, wherein the mechanical armis attached with a jujube-conveying pipe; the front part and the rear part of the jujube-conveying pipe are respectively connected with an air-suction negative-pressure pipe; the air-suction negative-pressure pipe is connected with the fan; one end of the jujube conveying pipe is communicated with the jujube suction opening on the mechanical arm, the other end is communicated with the jujube leafseparation device, the front part of the jujube suction opening is provided with a jujube claw, and the jujube leaf separation device is used for separating the jujube and the jujube leaf, and a red jujube grading device is arranged at the next station of the jujube leaf separation device, the red jujube grading device is used for grading the red jujube; and the tail end of the red jujube gradingdevice is provided with a red jujube collecting device. The machie adopts a negative-pressure air-suction type jujube-absorbing and a jujube claw auxiliary picking mode, so that the working efficiencyis improved, the hard contact of the picking device and the red jujube is avoided, the peel of the jujube is protected, and the jujube picking is more thorough.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a mechanically assisted negative pressure collection jujube leaf separation automatic jujube picking machine. Background technique [0002] In recent years, the market demand for jujubes has become higher and higher. Different jujube tree planting scales have been formed in various parts of my country according to their own conditions, which has created huge profits. However, jujube picking has become a major problem for farmers. [0003] The ripening time of jujube is generally from the middle and late September to the first ten days of October every year. At present, the known methods of picking jujube trees are mostly divided into two types: the first is manual picking, and this picking method is usually a multi-person cooperation. Climbing to the jujube tree and picking them off one by one by hand, or knocking off the dates with bamboo poles or wooden sticks, the workload...

AI Technical Summary

Problems solved by technology

It can be foreseen that in the next 3 to 5 years, after the newly planted jujube trees enter the full fruit period, there will be problems in fruit harvesting operations due to labor shortages and untimely harvesting, which will directly affect the quality of jujubes and cause a lot of losses

This is because jujube picking is a labor-intensive operation. Because the market has high requirements for the appearance of the fruit, there should be no mechanical damage such as bruises, scratches, and fracturing. It is necessary to be careful when harvesting. The above reasons determine the quality of jujubes. Picking is a time-consuming, labor-intensive and labor-intensive operation

The speed of manual picking of red dates is very slow. When large-scale development of jujube trees is planted, it is necessary to rely on mechanized picking to improve efficiency.

Due to the large amount of labor in jujube picking, the production cost is too high, and it is impossible to provide consumers and dried fruit processing enterprises with raw materials with sufficient quantity, superior quality and relatively low price, which is very unfavorable for enterprises to directly participate in market competition

[0005] At present, the jujube mechanical picking technology in the domestic and foreign markets has a single function; the structure of the separation device is too complicated, and the separation effect is not ideal; it has little effect in reducing the workload of jujube farmers and improving work efficiency, and farmers are not very satisfied
