Abstract

A combine side-shaking control system includes a sieve for separating crop material from other materials and configured to move in a fore-aft direction. At least one side-shaking assembly includes a mounting device attached to a combine chassis, a lower plate configured to rotate about a lower plate axis and an upper plate configured to (i) have an upper plate rotational motion and rotate responsive to the rotation of the lower plate and (ii) have an upper plate substantially linear motion in a substantially linear direction. A fixed arm is rotatably coupled to the upper plate and attached to the sieve. An actuation device is configured to rotate the lower plate about the lower plate axis. Responsive to the rotation of the upper plate, the sieve is controlled to move diagonal to the fore-aft direction in the substantially linear direction of the upper plate substantially linear motion.

First claim

What is claimed is:

1. A combine side-shaking control system, comprising:
(I) a sieve for separating crop material from other materials and configured to move in a fore-aft direction;
(II) at least one side-shaking assembly comprising:
a mounting device attached to a combine chassis;
a lower plate rotatably coupled to the mounting device and configured to rotate about a lower plate axis;
an upper plate coupled to the lower plate and configured to (i) have an upper plate rotational motion and rotate responsive to the rotation of the lower plate and (ii) have an upper plate substantially linear motion in a substantially linear direction,
a first pivot arm (i) coupled to the lower plate at a first lower plate pivot portion and (ii) coupled to the upper pivot plate at a first upper plate pivot portion; and
a second pivot arm (i) coupled to the lower plate at a second lower plate pivot portion spaced from the first lower plate pivot portion and (ii) coupled to the upper pivot plate at a second upper plate pivot portion spaced from the first upper plate pivot portion; and
a fixed arm rotatably coupled to the upper plate and attached to the sieve; and

(III) an actuation device (i) attached to the combine chassis, (ii) coupled to the lower plate and (iii) configured to rotate the lower plate about the lower plate axis,
wherein, responsive to the rotation of the upper plate, the sieve is controlled to move diagonal to the fore-aft direction within a plane including the sieve in the substantially linear direction of the upper plate substantially linear motion.

2. The combine side-shaking control system of claim 1 ,
wherein the sieve is further controlled to move in the substantially linear direction of the upper plate substantially linear motion which is substantially perpendicular to the first pivot arm and the second pivot arm.

3. The combine side-shaking control system of claim 1 , wherein
the lower plate and the upper plate are configured to rotate between a non-engaging position and at least one engaging position;
the upper plate is configured to (i) have a non-engaging motion in a non-engaging substantially linear direction and (ii) have an engaging motion in an engaging substantially linear direction different from the non-engaging substantially linear direction;
the sieve is controlled to (i) remain stationary or move in the fore-aft direction when the lower plate and the upper plate are in the non-engaging position, and (ii) move diagonal to the fore-aft direction in the engaging substantially linear direction of the upper plate substantially linear motion when the lower plate and the upper plate are in the at least one engaging position.

4. The combine side-shaking control system of claim 3 , wherein
the at least one engaging position further comprises a first engaging position and a second engaging position;
the lower plate and the upper plate are further configured to (i) rotate to the first engaging position and (ii) rotate to the second engaging position;
the upper plate is configured to (i) have a first engaging motion in a first engaging substantially linear direction and (ii) have an second engaging motion in a second engaging substantially linear direction different from the first engaging substantially linear direction; and
