Design And Research Of Stripping Device For Automatic Machine Of Surface Soil Stripped

With the development of Agriculture, The quality of the agricultural land surface planting soil replacement and transplantation application gradually be developed and recycling In the construction of high standard farmland demonstration project. Meanwhile transplantation and recycling of used gradually developed, with the help of precise planting soil agricultural machinery automation, its replace extensive planting soil is adapt to the new trend of modern agricultural development. At present, no reports of relevant for overburden stripping machine dedicated machinery, and products, so now the overburden stripping operations is the main tool construction machinery excavator or used for extensive stripping, stripping effect is poor, serious damage to soil structure, soil fertility to short time to recover after stripping.Surface planting soil demand at present, the existing topsoil stripping equipment cannot meet the demand of agronomy and soil sustainable utilization principle, in order to achieve both peel can meet the demand of agronomy and soil protection, stripped the soil, this paper developed a controllable, overburden stripping depth on soil ecological destruction is small, simple operation, easy maintenance, small size and high efficiency of an automated topsoil stripping equipment automatically, can make stripping machine in the process of operation, can realize the adjustment of the depth and the vibration frequency and very smooth stripped topsoil, guarantee the unsoiled meets the requirements. Mainly by the crawler drive, steering, hydraulic depth adjusting mechanism, the oscillating stripping mechanism, The device using two-dimensional vibration drag reduction principle to design the high frequency vibration stripping device, stripping device adopts the coupled mechanism to realize two dimensional vibration cutting;The profiling wheel, photoelectric sensor, hydraulic cylinder parts is simple and efficient stripping depth adjusting mechanism. In this paper.The main content for the stripping mechanism design and research, in the further study of the two-dimensional vibration based on the principle of drag reduction of stripping knife under various working conditions of kinematics analysis, analyzed the knife plate in various working condition of bearing, two-dimensional vibratory cutting soil is proved the correctness of the mechanism of drag reduction. Based on the coupled dynamics theory the stripping mechanism is obtained and the constraint equations for the plate spring body then build the stripping mechanism kinematics equation. Stripping machine for the overall scheme design and 3d modeling, the stripping mechanism through ADAMS kinematics, dynamics simulation analysis after point marker point velocity, acceleration and constraint reaction curve, to rest in the process of its motion stability analysis are done on the structure and optimized. On the basis of the analysis on the vibration characteristics of its unstable modal and vibration mode, demonstrates the presence of resonance. Of its key parts such as plate spring and stripping knife in finite element analysis and concluded that the stress concentration and easy broken parts and optimization. The rationality of the design are verified through the experiment and data analysis.Throughout the content of this article, from the perspective of the theory research, on the basis of mechanism analysis application of three-dimensional modeling software to complete the mechanism of the construction of the virtual machine, using the simulation software to complete the mechanism kinematic characteristics, dynamic characteristics and vibration characteristic analysis. Through the simulation results of the unreasonable structure, parameter optimization and modification, scheme is verified by experiments, and the feasibility and rationality of the save the design cost and time. In this paper, the results of the study and for the application of two dimensional vibration cutting and resistance principle provide theoretical guidance. Provide a reference for the coupled mechanical system design and using for reference.
