| The inertia reciprocating vibrating screen is a common screening machinery and equipment,with its smooth vibration,simple structure,high efficiency in engineering practice is widely used.However,with the development of science and technology and the continuous improvement of people’s needs,the vibration motor bearing life is short,work noise,high energy consumption and a series of shortcomings for people criticized.Therefore,based on the study of inertial reciprocating vibration machinery and anti-resonance theory,a basic mechanism design of anti-resonance vibrating screen is proposed.The rotating machine with deflection block is installed on the motor rack and In the frame of the rubber spring,while the metal coil spring to connect the vibration box and motor rack,which can greatly reduce the vibrating screen work motor vibration,thereby enhancing the life of motor bearings,while reducing noise and energy saving.Firstly,the anti-resonant vibrating screen is modeled in mathematics and mechanics to understand the vibration phenomena and characteristics of the vibration model under different conditions,and analyze the relationship between the parameters that affect the vibration and its internal existence.Secondly,after theoretical calculations and engineering tests,a single metal coil spring can be used only in industries with amplitudes of no more than 2 mm,and when more than 2mm,the sieves will be separated from the springs,not only the original Two degrees of freedom vibration mechanics and mathematical model,but also has a certain risk.In order to further enhance its engineering application value and the scope of use,now with two springs composed of "eight" shaped spring configuration structure to improve the original spring mechanism,analysis and verification of the actual composition of the composition of the stiffness coefficient.Finally,the stability and feasibility of the structure are verified by the method of engineering prototype experiment,and the law of the actual vibration phenomenon is analyzed. |
