Description
Technical field
The present invention relates to a kind of three-dimensional motion vibratory sieve mechanism, specifically, is that parallel kinematic vibratory sieve for parallel-connection structure, parallel kinematic amusement equipment, parallel robot etc. provide a kind of three-dimensional motion mechanism.
Background technology
Most typical traditional vibratory sieve is mainly circular shale shaker and linear vibrating screen at present, by inertia vibration generator, produce vibration, complex structure, its movement locus is approximately circle or straight line, owing to being motion in one dimension, and amplitude is little, and materials overturning is insufficient, sieve aperture is easily blocked by " sieve grain ", thereby causes screening efficiency lower.
Number of patent application 2006100881264 provides a kind of two degrees of freedom space mechanism for parallel kinematic equipment, the output movement of its platform is a translation in space, two rotations, wherein, one is dependent motion, because the motion of each member is in three dimensions, therefore the space that, machine accounts for is larger.The present invention designs a kind of plane variable freedom three-dimensional motion vibratory sieve mechanism, and its output movement is two translations, a rotation, and all moving links of machine, in a plane, are applicable to the less occasion in vertical direction space.
Summary of the invention
The object of the invention is to provide a kind of plane and becomes the controlled three-dimensional motion vibratory sieve of input mechanism,
Technical scheme of the present invention is: a kind of plane becomes the controlled three-dimensional motion vibratory sieve of input mechanism, comprise screen frame (6), frame (0), first, second side chain that structure is identical, and the 3rd side chain, one end of the member two (2) of the first side chain is with revolute pair three (R
3) connecting screen frame (6), the other end is with revolute pair two (R
