Plane type variable input and controllable 3D movement vibrating sieve mechanism

Abstract

The invention provides a plane type variable input and controllable 3D movement vibrating sieve mechanism. The mechanism comprises a sieving frame (6), a rack (0), a first branch chain, a second branch chain and a third branch chain, wherein the three branch chains have the same structure. The mechanism is characterized in that one of the ends of parts (2, 3) of the first branch chain and the second branch chain is respectively connected with the sieve frame (6) through rotating pairs (R3, R4), and while the other one of the ends of parts (2, 3) of the first branch chain and the second branch chain is respectively connected with one of the ends of the parts (1, 4) through rotating pairs (R2, R5); the other one of the ends of the parts (1, 4) is respectively connected with the rack (0) through rotating pairs (R1, R6); one end of a part (5) of the third branch chain is connected with the sieve frame (6) through the rotating pair (R7) and while the other end of the part (5) is connected to one end of a part (7) through a rotating pair (R8); the other end of a part (7) is connected with the rack (0) through a rotating pair (R9); the axes of all rotating pairs are parallel; the rotating pairs (R3, R4, R7) are not in a straight line; driving rods (1, 4, 7) can be controlled to move, and then the sieve frame can gain two-translation and one-rotating type output.

Description

technical field [0001] The invention relates to a three-dimensional motion vibrating screen mechanism, in particular, it provides a new type of three-dimensional motion mechanism for parallel structure parallel motion vibrating screens, parallel motion entertainment equipment, parallel robots and the like. Background technique [0002] At present, the most typical traditional vibrating screens are mainly circular vibrating screens and linear vibrating screens. Vibrations are generated by inertial exciters, and the structure is complex. Insufficient turnover of materials, the sieve holes are easily stuck by "sieve grains", resulting in low screening efficiency. [0003] Patent application number 2006100881264 provides a two-degree-of-freedom space mechanism for parallel motion equipment. The output motion of the platform is one translation and two rotations in space, and one of them is a dependent motion. Since the motion of each component is in three dimensions In the space...

[0002] At present, the most typical traditional vibrating screens are mainly circular vibrating screens and linear vibrating screens. Vibrations are generated by inertial exciters, and the structure is complex. Insufficient turnover of materials, sieve holes are easily stuck by "sieve grains", resulting in low screening efficiency

[0003] Patent application number 2006100881264 provides a two-degree-of-freedom space mechanism for parallel motion equipment. The output motion of the platform is one translation and two rotations in space, and one of them is a dependent motion. Since the motion of each component is in three dimensions space, therefore, the machine occupies a larger space
