Design And Research On The Tomato Turning Vine Machine

Xinjiang is China's processing tomato production in main producing areas is the implementation of the whole tomato industry demonstration zone mechanization. For the mechanization of tomato harvesting of existing field operations and reduce labor intensity and improve production efficiency. Papers on the mechanism's research of tomato turning vine, design tomato turning vine machine, to solve the mechanization of tomato harvesting is currently the main problems. Paper closely linked to Xinjiang tomato cropping patterns and growth conditions to study the core work components of tomato turning vine machine - the separating vine device and pushing vine device structure and working principle. Analysis of nearside vine process, study the mechanism of nearside vine. Determine the structure of the various components of size, operating parameters and their impact on the course of their work a major factor. Analysis of structure movement and force, use the methods of computer simulation to optimize the structure parameters. Obtain valuable structure, parameters and analytical methods to make physical prototype and develop products in the future. This paper studies include:(1) Tomato turning vine machine of mechanism and virtual prototyping technology of the theory in-depth study, on this basis the use of Pro/E three-dimensional physical design software to complete the prototype of tomato turning machine modeling, and virtual assembly of the constructions to form a tomato turning machine's virtual prototype model assembly. Moreover,Structure and mechanical analysis carried out.(2) Designed the separating vine device, analyzed the structure of and the working principle. Analysis of Analysis of the size of the separating vine's front rake and separate angle to make influence of raising vine and pushing vine. The movement condition of pushing vine roller in the work of analysis. And analysis of pushing vine roller's weight and installation angle to make influence of pushing vine roller by force. With an analysis of the experimental method of rattan on tomato vine off from the force required. In addition, to make the theoretical analysis about pushing vine roller on the tomato's the impact force.(3) The establishment of a rack of statics model to determine the calculation content of static: there are two conditions for the calculation of statics, an analysis of the conditions of the main beam results by force. Make an analysis to the rack of the modal analysis. Make an analysis to the previous six-and-order natural frequency and vibration mode. Optimization of the rack's construction makes use of design of optimization.(4) Used the Pro/E software and ADAMS software's specific interface module Mech/Pro, success to solve the question Pro/E and ADAMS software soft pieces of data transmission. The virtual assembly model of the tomato turning machine which establishes in Pro/E inducts to the ADAMS software, exerts the restraint, the force and the movement incentive. Soft pieces of the use of ADAMS on the tomato turning machine virtual prototype machine for dynamic simulation and kinematics, dynamics analysis. Get pushing vine roller trajectory figure, the force curve, the separating vine device's force curve and the movement curves figures, analysis of the results of figures. They provide a detailed for reference the design of the physical prototype.
