SYSTEM FOR CHOPPING AND SPREADING RESIDUE

摘要

A system of chopping and spreading residue for an agricultural combine comprises a chopper disposed in front of a residue accelerator at the rear of an agricultural combine. The chopper is disposed to receive crop residue from a threshing and separating section of the combine and to chop that residue into smaller portions, the residue accelerator is disposed behind the chopper to receive the chopped crop residue from the chopper, and to accelerate it.

主权项

1. A system of chopping and spreading residue in an agricultural combine comprises:
a chopper (102) disposed in a crop residue flow path to receive crop residue from a threshing and separating mechanism, the chopper having a rotational axis that extends horizontally and transversely to a harvesting direction of travel; a residue accelerator (104) disposed downstream of the chopper to receive chopped residue from the chopper and to accelerate the chopped residue; a residue spreader (112) disposed downstream of the residue accelerator (104) to spread the chopped residue accelerated by the residue accelerator (104); wherein the residue accelerator (104) further comprises an elongate drum (118) having a rotating axis that is disposed horizontally and transversely to the harvesting direction of travel of the agricultural combine, a plurality of rings (120) extending about the elongate drum (118) and fixed to the elongate drum (118), a plurality of vanes (122) extending between and fixed to each adjacent pair of rings (120), a vane extension (124) removably fixed to each of the plurality of vanes (122).
