Abstract

A soil sampling apparatus comprising a motorized vehicle may be used to remove soil samples at intervals over a field of interest. The apparatus comprises a sampling assembly that rotates and extends downwardly into the soil to collect a sample. The probe assembly is raised to dump the sample into a collection assembly, which transfers the sample to a bagging assembly, where the sample may be bagged for later analysis.

Claims

1. A soil sampling apparatus, comprising:

(a) a motorized vehicle, wherein said motorized vehicle comprises a bed and a cab;

(b) a probe assembly mounted to said bed of said vehicle, wherein said probe assembly comprises a soil sample probe, and wherein said probe assembly is rotatable and extendible to move from a first upright, retracted position to a second downwardly pointed, extended position whereby said probe is extended into the soil;

(c) a collection assembly mounted to said bed of said vehicle, wherein a portion of said collection assembly extends into said cab of said vehicle, and whereby soil deposited in said probe assembly may be collected; and

(d) a bagging assembly mounted to said cab of said vehicle, whereby soil deposited from said collection assembly may be bagged for later analysis.

2. The soil sampling apparatus of claim 1, wherein said probe assembly comprises a probe shaft pivotally connected to said motorized vehicle.

3. The soil sampling apparatus of claim 2, further comprising a guide plate rotatably connecting said probe shaft and said vehicle, wherein said probe shaft may extend and retract with respect to said guide plate.

4. The soil sampling apparatus of claim 3, further comprising at least one roller attached to said guide plate and in contact with said probe shaft.

5. The soil sampling apparatus of claim 2, further comprising a probe arm connected to said probe shaft and to said vehicle.

6. The soil sampling apparatus of claim 5, wherein said probe arm is hingeably articulated.

7. The soil sampling apparatus of claim 6, further comprising a hydraulic cylinder in communication with said probe arm.

8. The soil sampling apparatus of claim 1, wherein said probe comprises a probe tip comprising a distal end and a hollow interior having a diameter that is greater at a point further from said distal end of said tip than appoint closer to said distal end of said tip.

9. The soil sampling apparatus of claim 8, wherein said probe further comprises a hollow tube attached to said probe tip, and wherein said probe tip is removably attached to said hollow tube.

10. The soil sampling apparatus of claim 1, further comprising a plurality of probe assemblies.

11. The soil sampling apparatus of claim 1, wherein said collection assembly comprises a transverse auger tray positioned beneath said probe when said probe is in said first position.

12. The soil sampling apparatus of claim 11, wherein said collection assembly further comprises an auger positioned within said transverse auger tray.

13. The soil sampling apparatus of claim 12, wherein said collection assembly further comprises a rotor within a rotor housing, said rotor positioned beneath and extending partially into said transverse auger tray such that said transverse auger is operable to deliver soil to said rotor.

14. The soil sampling apparatus of claim 13, wherein said collection assembly further comprises a rotor brush in contact with said rotor and operable to clean said rotor.

15. The soil sampling apparatus of claim 13, wherein said collection assembly further comprises a longitudinal auger tray beneath said rotor housing.

16. The soil sampling apparatus of claim 15, wherein said collection assembly further comprises a longitudinal auger with said longitudinal auger tray.

17. The soil sampling apparatus of claim 16, further comprising at least one chopping blade with a chopping blade housing, said chopping blade positioned at an end of said longitudinal auger tray such that said longitudinal auger is operable to deliver soil to said chopping blade.

18. The soil sampling apparatus of claim 17, further comprising a chopping blade brush in contact with said chopping blade and operable to clean said chopping blade.

19. The soil sampling apparatus of claim 17, wherein said bagging assembly further comprises a rotatable bag tray positioned beneath said chopping blade housing to receive soil from said chopping blade assembly.

20. The soil sampling apparatus of claim 19, further comprising a plurality of bags positioned on said bag tray.
