Abstract

The invention provides a method and a device for eliminating shutdown impact of a vibration sieve, belonging to vibration damping method and device. The vibration sieve is connected with a fixed bottom plate by a spring and is connected with a piston rod; a piston cylinder body is connected with the fixed bottom plate; a bypass electromagnetic valve is connected between a rod chamber oil hole and a rod-less chamber oil hole in the piston cylinder body; the rod chamber oil hole is connected with a damping electromagnetic valve that is connected with one end of a first absorber and a second absorber; the first absorber is connected in parallel with the second absorber; and the other ends of the first absorber and the second absorber are connected with the rod-less chamber oil hole. The method and the device have the advantages that the impact load generated by the vibration sieve is converted into hydraulic energy; the vibration energy is moved out of a vibration source; the vibration energy is absorbed by bidirectional self-tuning of the two absorbers, so that the impact load is instantaneously converted into the heat energy that is released; and the vibration impact force generated by shutdown is not directly acted on the motor and the vibration mechanism, thus reducing maintenance quantity and failure rate.

Description

Technical field [0001] The invention relates to a vibration damping method and device, in particular to a method and device for eliminating the impact of a vibrating screen during shutdown. Background technique [0002] Currently used vibrating screens, especially vibrating screens with high-power vibration sources, often fail in motors and vibrating mechanisms in applications. People usually consider them to be inherent shortcomings of vibrating screens. Most of them take measures to increase maintenance to delay the occurrence of failures. Important occasions must be maintained every day. In fact, this is a misunderstanding that people recognize, because the vibration energy needs a certain time to gradually attenuate when the machine is stopped, and the vibration mechanism will immediately stop working, so that the vibration energy will generate an impact force on the vibration mechanism. After long-term impact, the fasteners of the vibrating mechanism are easily loosened, ca...
