Abstract
The driving mechanism has a drive shaft which rotates a driving block. A cam is mounted for rotation to the driving block and is received in a slot of a follower. As the cam rotates, it rolls backwards and forwards in the slot and causes the follower to rotate. A connecting rod is affixed to the follower and is rotated by it. The connecting rod rotates about an axis parallel to, but offset from, the axis about which the drive shaft rotates. The rate of rotation of the drive shaft is unvarying whereas the connecting rod rotates at a varying rate. A crank is affixed to the connecting rod and imparts reciprocating motion to the tray. A link can be substituted for the cam.
Claims5
A driving apparatus for a shaking tray on which particulate material advances, comprising
- a cam;
- a drive shaft rotating about an axis and causing said cam to rotate;
- a follower having a slot formed therein for receipt of said cam, said cam as it rotates, moving backward and forward in said slot and imparting rotation of 360 degrees to said follower;
- a connecting rod affixed to said follower and being rotated 360 degrees thereby upon rotation of said follower, said connecting rod rotating about a stationary axis parallel to but offset from the axis of rotation of said drive shaft;
- a crank connected to said connecting rod and adapted to be operatively connected to the shaking tray for imparting reciprocating motion to said tray upon rotation of said crank by said connecting rod.
