Compression rolls on baler pick up

摘要

A baler comprises a pick-up assembly configured to pick-up crop material; a compression assembly comprising at least one pair of opposing compression rollers configured to generate a pressure on the crop material as it passes between the compression rollers; and a bale chamber, wherein the pre-compressed crop forms a bale. The compression rollers define an adjustable gap therebetween. By adjusting the gap, pressure exerted on the crop material as it passes between the compression rollers may be controlled, resulting in bales of varying density.

1. A baler comprising:
a pick-up assembly; a bale chamber configured for forming bales; a compression assembly located between the pickup assembly and bale chamber configured for pre-compressing crop prior to entering the bale chamber, the compression assembly comprising at least one pair of opposing compression rollers configured to generate a pressure on crop material passed therethrough, wherein at least one of the at least one pair of compression rollers is mounted to a member moveable with respect to the other compression roller forming an adjustable gap therebetween, the compression assembly being configured to pre-compress the crop material passed therethrough; a pressure sensor connected to a controller, wherein the pressure sensor detects the pressure generated by the at least one pair of opposing compression rollers of the compression assembly on the crop material passed therethrough; and wherein the controller is configured to control an actuator connected to the at least one moveably mounted one of the pair of compression rollers such that pressure generated by the at least one pair of opposing compression rollers on the crop material passed therethrough is generally maintained.
