Abstract

A system and method for preparing a sample area of a bale in order to more accurately evaluate the plant material incorporated into the bale. A baler receives, compresses, shapes, and secures material into the bale. A cutter mechanism cuts a portion of the material in the bale into similarly-sized particles. A mixer mechanism mixes the particles into a homogenous aggregate. A compression mechanism compresses the homogenous aggregate into the bale. An NIR testing system receives and analyzes near-infrared radiation reflected by the homogenous aggregate, and generates evaluation data reflecting properties of the material. The cutter may include knives mounted in a compression chamber of the baler. The mixer may be a relief feature on a center rail, the compressor may be a projecting feature on the center rail, and an NIR sensor may be mounted to the center rail so as to press against the surface of the bale.

First claim

The invention claimed is:

1 . A system incorporated into a baler machine configured to receive a plant material and to compress, shape, and secure the plant material into a bale, the system comprising:
a cutter mechanism configured to cut a portion of the plant material in the bale into similarly-sized particles of the plant material; a mixer mechanism configured to mix the similarly-sized particles of the portion of the plant material into a homogenous aggregate of the portion of the plant material; a compression mechanism configured to compress the homogenous aggregate of the portion of the plant material into the bale; and a near-infrared testing system configured to receive near-infrared radiation reflected by the homogenous aggregate of the portion of the plant material, analyze the near-infrared radiation, and generate evaluation data reflecting one or more properties of the plant material in the bale, wherein the baler machine includes a compression chamber in which the plant material is compressed, shaped, and secured into the individual bale, and the cutter mechanism is positioned in the compression chamber so as to cut the portion of the plant material in the bale without damaging a binding material which secures the plant material into the bale, and the compression chamber includes a center rail structure, and the mixer mechanism is a relief feature on the center rail structure which allows the plant material to expand and mix after cutting.

2 . The system of claim 1 , wherein the cutter mechanism includes one or more serrated knives mounted in a fixed position such that bale moves against and is cut by the one or more serrated knives.

3 . The system of claim 2 , wherein the serrated knives are spring-loaded so as to control an amount of cutting force applied to the portion of the plant material in the bale.

4 . The system of claim 1 , wherein the relief feature is further configured to allow any plant material falling from the cutter mechanism to be regathered and mixed.

5 . The system of claim 1 , wherein the compression mechanism is a projecting feature on the center rail structure which physically pushes against the bale to compress the homogenous aggregate of the portion of the plant material so as to present a substantially flattened surface to a near-infrared sensor of the near-infrared testing system.

6 . The system of claim 5 , wherein the near infrared sensor is mounted to the center rail so as to cause the near-infrared sensor to exert a pressure against the surface of the bale.

7 . The system of claim 6 , wherein the near-infrared sensor is located on a floating assembly mounted to the center rail and configured to allow for controlling the pressure exerted against the surface of the bale.

8 . A system comprising:
a baler machine configured to receive a plant material and to compress, shape, and secure the plant material into a bale; a cutter mechanism including one or more serrated knives configured to cut a portion of the plant material in the bale into similarly-sized particles of the plant material; a mixer mechanism configured to mix the similarly-sized particles of the portion of the plant material into a homogenous aggregate of the portion of the plant material; a compression mechanism configured to compress the homogenous aggregate of the portion of the plant material into the bale; and a near-infrared testing system configured to receive near-infrared radiation reflected by the homogenous aggregate of the portion of the plant material, analyze the near-infrared radiation, and generate evaluation data reflecting one or more properties of the plant material in the bale, wherein
the baler machine includes a compression chamber in which the plant material is compressed shaped, and secured into the individual bale;
the cutter mechanism is positioned in the compression chamber so as to cut the portion of the plant material in the bale without damaging a binding material which secures the plant material into the bale; the compression chamber includes a center rail structure; the mixer mechanism is a relief feature on the center rail structure which is configured to allow the plant material to expand and mix after cutting; the compression mechanism is a projecting feature on the center rail structure which physically pushes against the bale to compress the homogenous aggregate of the portion of the plant material so as to present a substantially flattened surface to a near-infrared sensor of the near-infrared testing system; and the near infrared sensor is mounted to the center rail so as to cause the near-infrared sensor to exert a pressure against the surface of the bale.

9 . A method comprising:
receiving, compressing, shaping, and securing with a baler machine a plant material into a bale; cutting with a cutter mechanism a portion of the plant material in the bale into similarly-sized particles of the plant material; mixing with a mixer mechanism the similarly-sized particles of the portion of the plant material into a homogenous aggregate of the portion of the plant material; compressing with a compression mechanism the homogenous aggregate of the portion of the plant material into the bale; and receiving and analyzing with a near-infrared testing system near-infrared radiation reflected by the homogenous aggregate of the portion of the plant material, and generating with the near-infrared testing system evaluation data reflecting one or more properties of the plant material in the bale, wherein the baler machine includes a compression chamber in which the plant material is compressed, shaped, and secured into the individual bale, and the cutter mechanism is positioned in the compression chamber so as to cut the portion of the plant material in the bale without damaging a binding material which secures the plant material into the bale, and wherein the compression chamber includes a center rail structure, and the mixer mechanism is a relief feature on the center rail structure which is configured to allow the plant material to expand and mix after cutting.

10 . The method of claim 9 , wherein the cutter mechanism includes one or more serrated knives mounted in a fixed position such that bale moves against and is cut by the one or more serrated knives.

11 . The method of claim 10 , wherein the serrated knives are spring-loaded so as to control an amount of cutting force applied to the portion of the plant material in the bale.

12 . The method of claim 9 , wherein the relief feature is further configured to allow any plant material falling from the cutter mechanism to be regathered and mixed.

13 . The method claim 9 , wherein the compression mechanism is a projecting feature on the center rail structure which physically pushes against the bale to compress the homogenous aggregate of the portion of the plant material so as to present a substantially flattened surface to a near-infrared sensor of the near-infrared testing system.

15 . The method of claim 14 , wherein the near-infrared sensor is located on a floating assembly mounted to the center rail and configured to allow for controlling the pressure exerted against the surface of the bale.
