Abstract

The crop testing and evaluation system includes a plurality of measuring and testing devices that measure the weight, moisture content, and test weight of a crop. Other measuring devices that test the crop for characteristics such as protein content, sugar content, oil content and color may also be included. Mounting accessories are included in the system for attaching the measuring devices to the crop gathering compartment of a harvesting vehicle. As the crop is harvested and fed to the compartment, periodic readings of the measuring devices are taken by a microprocessor and supplied to a computer for analysis and evaluation. Preferably, the microprocessor and computer are positioned in the cab of the harvesting vehicle within reach of the harvest operator. The present invention also provides an efficient method of evaluating research products, such as plant hybrids and varieties.

Claims

1. A method of harvesting and analyzing harvest data in a field of plant hybrids or varieties, which comprises:

(a) harvesting the experimental plots of said plant hybrids or varieties with a combine having a testing and evaluating assembly removably attached thereto, and a computer on line with said assembly,

(b) recording the harvest data obtained from said harvesting of experimental plots,

(c) storing said harvest data in said computer, and

(d) generating reports in said field, wherein said testing and evaluating assembly comprises;

first crop collection means for collecting a first quantity of the crop;

weighing means for determining a weight of the first quantity of crop collected by said first crop collection means and outputting a first signal corresponding to the weight;

an attachment assembly comprising a support frame which is removably attached to the outer perimeter of a crop storage tank and at least two suspension members coupled to said frame, said weighing means and said first crop collection means, such that said first crop collection means is suspended in said crop storage tank; and

processing means for receiving and processing said first signal and determining a quality of the crop based on said first signal.

2. The method of claim 1, wherein said testing and evaluating assembly is removably suspended from the top of said crop storage tank.

3. The method of claim 1, wherein said testing and evaluating assembly has the capacity of holding in excess of 400 pounds of grain in said first crop collection means.

4. The method of claim 1, wherein said testing and evaluating assembly is removably attached to the inside of said crop storage tank.

5. The method of claim 1 wherein the harvesting of two or more of said experimental plots is accomplished in one continuous process across the test, without pausing or stopping between said plots.

6. A method of harvesting and analyzing harvest data in a field of plant hybrids or varieties, which comprises:

(a) harvesting said plant hybrids or varieties with a combine having a testing and evaluating assembly attached thereto, and a computer on line with said assembly,

(b) recording the harvest data obtained from said harvest of said plant hybrids or varieties,

(c) storing said harvest data in said computer, and

(d) generating reports in said field, wherein said testing and evaluating assembly comprises;

a vehicle having a crop storage tank therein;

weighing means coupled to said crop storage tank for determining a weight of a first quantity of crop collected in said crop storage tank and outputting a first signal corresponding to the weight;

first means for attaching said weighing means to said vehicle; and

processing means, coupled to the weighing means, for receiving and processing said first signal and determining a quality of the crop based on said first signal.

7. The method of claim 6, wherein said reports are generated by a spread sheet or database software package.

8. The method of claim 6, wherein said computer is located on said combine.

9. The method of claim 6, wherein said method of harvesting and analyzing harvest data is accomplished in one continuous process across said field, without pausing or stopping.
