detailed description

The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

As shown in Figure 1, a dual-sieve body self-balancing digging harvester drive vibration device includes a front sieve bed 1 and a rear sieve bed 2 connected front and back, and the front sieve bed 1 and rear sieve bed 2 are arranged in parallel up and down. Cloth, and the rear end of the front sieve bed 1 and the front end of the rear sieve bed 2 overlap up and down. The front ends of the left and right side panels of the front sieve bed 1 and the rear sieve bed 2 are respectively connected to the bottom ends of a pair of front double connecting rods 3 and the bottom ends of a pair of rear double connecting rods 4. The rear ends of the left and right side panels of the sieve bed 2 are respectively connected with a boom 5, and a connecting rod 6 is respectively connected between the hinge point in the middle of the front double connecting rod 3 on the same side and the top of the rear double connecting rod 4.
