First Claim
Patent Images
1. A position adjustment assembly for an agricultural product conveyor, which delivers a product to a storage system, such as an air cart, comprising:
- an inner arm having a first end rotatably coupled to the air cart and second end spaced from the agricultural product conveyor;
an outer arm having a first end spaced from the agricultural product conveyor and rotatably coupled to the second end of the inner arm at a pivot point and a second end rotatably coupled to the agricultural product conveyor;
andan intermediate link having a first end operatively connected to the air cart for guiding movement thereof, a second end operatively connected to the outer arm, and a length, the intermediate link further including a lateral positioning assembly to vary the length of the intermediate link;
wherein the outer arm rotates with respect to the second end of the inner arm about the pivot point in response to the lateral positioning assembly varying the length of the intermediate link.

15. A method of delivering product to an air cart from a supply vehicle via an agricultural product conveyor, comprising the steps of:
-
pivotably connecting a first end of an inner arm to the air cart; pivotably connecting a second end of the inner arm to an outer arm; pivotably connecting a second end of the outer arm to the product conveyor; connecting a cam to the arm cart; positioning a follower on a first end of an intermediate link in the cam and connecting a second end of the intermediate link to a first end of the outer arm; adjusting a position of the product conveyor with respect to the air cart according to the steps of; controlling a first linear actuator to rotate an inner arm relative to the air cart; and controlling a second linear actuator to vary a length of an intermediate link, wherein; the follower of the intermediate link follows the cam in response to rotation of the inner arm relative the cart, and an angle between the inner arm and an outer arm is adjusted in resonse to the varying of the length of the intermediate link. - View Dependent Claims (16, 17)
