Triaxial vibration-decreasing/vibration-isolating platform of hammer crusher

Abstract

The invention discloses a triaxial vibration-decreasing/vibration-isolating platform of a hammer crusher, wherein, the whole platform structure belongs to the space redundancy 3-DOF translational mechanism, converting the spatial vibration caused by all excitation forces during the working process of the hammer crusher to triaxial wire vibration by the constraint of the space redundancy 3-DOF translational mechanism, then converting the triaxial wire vibration of a moving platform to uniaxial wire vibration of a mechanical active pair through mutual transitive relations between the moving platform of space redundancy 3-DOF translational mechanism and kinematics and mechanics of the mechanical active pair; buffering and vibration isolation are realized by elastic cells of the active pair and decreasing vibration can be realized through consuming vibrational energy of the system by damping elements of the active pairs, frictional damping of all kinematic pairs, or damping elements connected directly with the moving platform, thus reducing the spatial vibration of the hammer crusher and harm to ambient environment effectively, economically and reliably. The invention has the advantages of rational design, light weight, low cost, small volume and easy assembly and maintenance management, etc.

Description

technical field [0001] The invention relates to a multi-axial vibration reduction and vibration isolation device for a ring hammer type coal crusher, belonging to the research field of crushing machinery vibration control technology and devices. Background technique [0002] The ring hammer coal crusher uses the ring hammer suspended on the high-speed rotating wheel to impact and crush the material first, and the impacted material is squeezed, sheared, and ground between the ring hammer and the sieve plate to be crushed. After further crushing and reaching the required particle size, it will be discharged through the screen plate and the grids of the upper and lower discharge plates; the sundries that cannot be broken will enter the iron discarding room through the ring hammer, and will be cleaned regularly manually. Compared with the impact type, hammer type, jaw type and roller type coal crushers, the ring hammer type coal crusher has adjustable discharge particle size, ea...
