A four connecting rod shale shakers of equiarm not for peanut harvester

The utility model discloses a four connecting rod shale shakers of equiarm not for peanut harvester has swing mechanism, and top and swing joint that this swing lies in the screen cloth are in the mount, swing mechanism is including the first initiative pendulum rod, second initiative pendulum rod, first driven pendulum rod, the driven pendulum rod of second and the support that lie in both sides, first, two distances of taking the initiative the first end of first end to the driven pendulum rod of pendulum rods equal the distance that seconds ends first, two initiative pendulum rods were held to seconds first, two driven pendulum rods, distances first, that two first ends to the seconds first, two initiative pendulum rods of taking the initiative pendulum rods are held are greater than the distance that first ends first, two driven pendulum rods were held to seconds first, two driven pendulum rods. These asymmetric two liang of correspondences of four connecting rod davits, can make the shale shaker in the motion process except that traditional planar motion, still form a space balleting that is favorable to reinforceing its vibration screening effect.
