The Design Of Portable Red Chinese-dates Vibration Harvester

As people health consciousness gradually strengthened, jujube large popular in recent years. Plant code and the expansion of the social demand, the traditional way of manual picking cannot meet the demand of market in China, red jujube harvest mechanization development become inevitable trend. At present, the vibrating red jujube harvest ways mainly include: pneumatic type, continuous, impingement. Continuous is the wide application in the field of vibrating harvest way. The method is based on a certain frequency of excitation force is used for Chinese jujube branches, subject branches to the role of force and reciprocating motion, because the red jujube has certain quality, when the red jujube and their branches have relative motion, red date inertia force is greater than the handle and place the adhesion strength of the branches, red jujube was dumped, complete and in the separation of stems.Work of this paper is to research and development for domestic dwarf dense planting cultivation mode using red harvester for basic research, first of all, on the analysis of the present situation of domestic and foreign research situation, combining with xinjiang dwarf dense planting jujube planting patterns, the physical and mechanical characteristics of red jujube, the test is measured and summarizes the relationship between the size of the red Chinese-dates separation force, determine the scope of the out of the red jujube separation force.Second, handheld red harvester vibration for the overall design, and using Solidworks software of 3 d modeling of the whole machine, complete the virtual assembly of the machine; Using the Adams software to harvest trajectory simulation, using Slidworks simulation modal of eccentric connecting rod intensity and eccentric connecting rod are analyzed; Draw connecting rod working when the maximum stress occurs in the end, but the maximum stress is far less than its yield strength; By Solidworks 3 d software with the Simulation of plug-in for handheld red harvester vibration modal of the transmission rod is analyzed, the working frequency of transmission rod away from its first six order natural frequency, thus the normal work of the eccentric vibration mechanism when will have resonance and lever.Finally, combining with the theory of mechanical design and mechanical analysis of design a handheld jujube harvest machine vibration, and making the prototype, a field experiment and repeatedly. Using computer virtual simulation technology and test results of the method of combining the harvest the machine performance to carry on the quantitative system research, through the analysis of test data, to complete the optimization of organization structure and performance parameters of the harvest.Handheld red harvester vibration design combines the characteristics of the current Chinese jujube development, on the design content mainly to apply vibration principle of red jujube harvest machine, improve the efficiency of the harvest, reduce the labor intensity of farmers, and greatly reduces the harvesting operation cost.
