Abstract
A draper assembly for a crop pick-up has an endless draper belt assembly wrapped around a smaller front roller and a larger rear drive roller where the endless draper belt assembly is formed by four endless belts connected side by side at spaced positions along their length for common movement around the rollers. A tracking guide device is defined by a plurality of plastic guide elements mounted in a row on an inside surface of one belt at longitudinally spaced positions along the belt length which cooperates with a groove in the drive roller so that there are least two guide elements in the groove at any point in time. The guide elements are wider than their length and can be fastened through the belt so as to connect to the mounting of some of the fingers on the exterior of the belt.
Claims19
A crop pick-up for a harvesting machine comprising:
- a front roller;
- a rear roller parallel to and spaced from the front roller;
- one of the front and rear rollers being a driven roller for driven rotation around its axis;
- an endless draper belt assembly wrapped around the front and rear rollers so that rotation of the driven roller acts to drive the belt assembly to carry crop rearwardly from the front roller to the rear roller;
- the endless draper belt assembly comprising a plurality of endless belts arranged side by side across the front and rear rollers so as to define two side belts and at least one intermediate belt;
- each belt comprising a belt length wrapped around the rollers and connected at ends of the belt length to form the respective endless belt;
- each endless belt being connected to its respective next adjacent endless belts at spaced positions along its length so as to connect the endless belts for common movement around the rollers;
- each of the front and rear rollers having a peripherally extending guide groove therein;
- and a plurality of guide elements mounted in a row along an inside surface of one of the endless belts for tracking in the guide grooves in the front and rear rollers;
- the guide elements being separate each from the next so as to be fastened at spaced positions along said one of the endless belts;
- the guide elements being fastened each by a respective separate fastener passing through said one of the endless belts.
