Abstract

An automated programmable processor-controlled system and related methods for packaging an agricultural sample such as soil which may be tested for various chemical properties such as plant available nutrients. The packaging system includes a sample packaging apparatus which allows raw bulk sample material collected in the agricultural field to be expediently and conveniently containerized for processing and analysis. The apparatus may include a die block disposed between bulk material and sample collection chambers. A sample blade mechanism inserts a sample blade array through the bulk material chamber and die block. The sample blades extrude the sample material from the bulk material chamber through die slots in the die block, thereby forming plugs or blanks of the material collected in the sample collection chamber coupled to the sample container. A cleaning blade mechanism inserts a cleaning blade array through the die slots after the extrusion for removing residual soil or debris.

First claim

1 . An agricultural sample packaging apparatus comprising:
a bulk material chamber configured for receiving a sample; a sample collection chamber; a die block disposed between the bulk material and sample collection chambers, the die block including a plurality of through die slots in communication with the bulk material and sample collection chambers; a sample blade mechanism comprising a plurality of elongated sample blades movably insertable through the bulk material chamber and die slots from a first side of the die block, wherein the sample blades are operable to extrude the sample from the bulk material chamber through the die slots and into the sample collection chamber.

2 . The apparatus according to claim 1 , wherein the apparatus comprises a rotatable carousel including a container holder configured to removably hold a sample container.

3 . The apparatus according to claim 2 , wherein the carousel is rotatable between an inward closed position in which the sample container is positioned beneath the sample collection chamber and an outward open position in which the sample container is not beneath the sample collection chamber.

4 . The apparatus according to claim 2 , wherein the apparatus comprises a cleaning blade mechanism comprising a plurality of elongated cleaning blades movably insertable through the sample collection chamber and die slots from a second side of the die block.

5 . The apparatus according to claim 2 , further comprising a compaction piston-plunger configured to compress the sample in the bulk material chamber.

6 . The apparatus according to claim 5 , further comprising a sample transfer piston-plunger configuration to force the sample downwards and outwards from the sample collection chamber.

7 . The apparatus according to claim 2 , further comprising a programmable controller configured to control operation of the sample packaging apparatus.

8 . The apparatus according to claim 2 , wherein the sample is soil.

9 . The apparatus according to claim 2 , wherein the apparatus comprises a support frame configured for mounting to a mobile vehicle.

10 . The apparatus according to claim 1 , wherein each of the sample blades comprises a compression spring.

11 . The apparatus according to claim 10 , wherein each sample blade comprises a bifurcated end comprising a pair of the springs which act on a pair of spaced apart spring plates coupled to each sample blade.

12 . A method for packaging an agricultural sample comprising:
adding a sample to a bulk material chamber; inserting a plurality of sample blades through the bulk material chamber; forcing the sample through a die block with the sample blades forming sample material plugs; and collecting the sample material plugs in a sample collection chamber.

13 . The method according to claim 12 , further comprising before the insertion step, a step of rotating a carousel holding a sample container and positioning the sample container beneath the sample collection chamber.

14 . The method according to claim 13 , further comprising depositing the sample material plugs in the sample container.
