Embodiment Construction

[0013] refer to figure 1 The sugarcane harvester 10 illustratively includes a cutter 12, a left crop divider reel and a right crop divider reel 14 (the left crop divider reel 14 is not shown), an upper push-down roller and a lower push-back roller (pull down rollers not shown), undercutter assembly 16, feeder 18, chopper 20, primary extractor 22, elevator 24 and secondary extractor 26. The tip cutter 12 cuts off the leafy tip of the sugarcane plant. The left and right crop divider reels 14 lift the sugarcane beads to feed the throat of the harvester 10 .

[0014] The undercutter assembly 16 is used to cut off the sugarcane stalk pushed forward by the knockdown rollers and feed the cut sugarcane stalk to the feeder 18 . The feed system 18 receives the pile of chopped sugar cane from the undercutter assembly 16 and feeds the pile of chopped sugar cane back. The chopper 20 receives the pile of chopped cane from the feeder 18 and cuts the cane stalks into short lengths. Downst...

Abstract

A chopper system for a sugarcane harvester comprises a chopper and a timing-adjustment tool. The chopper comprises a first chopper drum mounted for rotation about a first axis of rotation and comprising blades, a second chopper drum mounted for rotation about a second axis of rotation and comprising blades that cooperate with the blades of the first chopper drum to sever sugarcane stalks into billets upon rotation of the first and second chopper drums respectively about the first and second axes of rotation, and a gearbox that coordinates rotation of the first and second chopper drums relative to one another to establish a timing of operation between the blades of the first and second chopper drums. The timing-adjustment tool removably mounts to the chopper to adjust the timing of operation.

Description

technical field [0001] The present disclosure relates to a chopper for a sugarcane harvester. Background technique [0002] Sugarcane harvesters typically have a chopper that is used to cut a bunch of sugarcane stalks into sections called "shorts". The chopper has a first chopper drum and a second chopper drum, each chopper drum having a set of blades and being rotatable about a respective axis of rotation. The blades of the chopper drum cooperate to chop the stalk into short pieces. Blade wear affects the timing of operation between the blades of the first chopper drum and the blades of the second chopper drum, thereby affecting the cut quality of the stalks. Contents of the invention [0003] According to one aspect of the present disclosure, a chopper system for a sugarcane harvester is disclosed. The chopper system includes a chopper and a timing adjustment tool. The chopper includes a first chopper drum mounted to rotate about a first axis of rotation and comprisi...
