Abstract

A soil sampler assembly includes a utility vehicle and a soil sampler module coupled to the utility vehicle. The utility vehicle includes a cab, and the soil sampler module is configured to deposit a soil sample in the cab. For example, the soil sampler assembly includes a conveyor system configured to convey the soil sample to the cab. The conveyor system includes a central conveyor and a lateral conveyor that feeds the central conveyor. The central conveyor is on a travel track. The soil sampler assembly further includes a sampler arm assembly. The sampler arm assembly includes a power cylinder, a guide cylinder, a transfer block, and a probe. The probe has a tip, and the tip of the probe includes an outer surface defining an outer taper bore and an inner surface defining an inner taper bore.

Claims

1. A soil sampler assembly comprising:

a utility vehicle, the utility vehicle comprising a cab;

a soil sampler module coupled to the utility vehicle, the soil sampler module configured to deposit a soil sample in the cab; and

a conveyor system configured to convey the soil sample to the cab, the conveyor system including a central conveyor belt extending longitudinally through the soil sampler module and a lateral conveyor belt extending through the soil sampler module from a side of the soil sampler module to the conveyor belt at an orientation at least substantially perpendicular to the central conveyor belt.

2. The soil sampler assembly as recited in claim 1, wherein the utility vehicle comprises a diesel powered power vehicle.

3. The soil sampler assembly as recited in claim 1, wherein the central conveyor belt is on a travel track.

4. The soil sampler assembly as recited in claim 1, wherein the soil sampler module comprises a power sprocket for powering the conveyor system and a drive sprocket for driving a conveyor of the conveyor system, and a ratio of the power sprocket to the drive sprocket is about two-to-one (2:

1).

5. The soil sampler assembly as recited in claim 1, further comprising a sampler arm assembly, wherein the sampler arm assembly is supported by at least one of the utility vehicle or the soil sampler module.

6. The soil sampler assembly as recited in claim 5, wherein the sampler arm assembly comprises an auger.

7. The soil sampler assembly as recited in claim 5, wherein the sampler arm assembly comprises a proximity switch.

8. The soil sampler assembly as recited in claim 1, further comprising a probe coupled to the soil sampler module, the probe configured to obtain a core comprising the soil sample.

9. The soil sampler assembly as recited in claim 8, wherein the probe tapers to define a tip comprising an outer surface defining an outer taper bore and an inner surface defining an inner taper bore.

10. The soil sampler assembly as recited in claim 9, wherein a ratio of an inside diameter of the inner surface distal to the end of the tip to an inside diameter of the inner surface proximal to the end of the tip is between about two-to-one (2:

1) and about one and two-thirds-to-one (1.67;

1), and the inner surface of the inner taper bore extends farther with respect to the length of the probe than the outer surface of the outer taper bore.

11. The soil sampler assembly as recited in claim 9, wherein the soil sampler module comprises a brush positioned proximate to the tip of the probe when the probe is oriented in a generally vertical orientation.

12. The soil sampler assembly as recited in claim 1, further comprising a self-resetting knockout peg assembly configured to at least one of eject the soil sample from the soil sampler module onto the conveyor system or perform a reset operation when the soil sample contacts a knockout peg but is not ejected from the soil sampler module.

13. A soil sampler assembly comprising:

a utility vehicle comprising a cab;

a soil sampler module coupled to the utility vehicle, the soil sampler module configured to deposit a soil sample in the cab;

a conveyor system configured to convey the soil sample to the cab, the conveyor system including a central conveyor belt extending longitudinally through the soil sampler module and a lateral conveyor belt extending through the soil sampler module from a side of the soil sampler module to the conveyor belt at an orientation at least substantially perpendicular to the central conveyor belt; and

a sampler arm assembly coupled to the soil sampler module, the sampler arm assembly configured to collect the soil sample.

14. The soil sampler assembly as recited in claim 13, wherein the utility vehicle comprises a diesel powered power vehicle.

15. The soil sampler assembly as recited in claim 13, wherein the soil sampler module comprises a power sprocket for powering the conveyor system and a drive sprocket for driving a conveyor of the conveyor system, and a ratio of the power sprocket to the drive sprocket is about two-to-one (2:

1).

16. The soil sampler assembly as recited in claim 13, wherein the sampler arm assembly comprises a probe configured to obtain a core comprising the soil sample.

17. The soil sampler assembly as recited in claim 16, wherein the probe tapers to define a tip including an outer surface defining an outer taper bore and an inner surface defining an inner taper bore, wherein a ratio of an inside diameter of the inner surface distal to the end of the tip to an inside diameter of the inner surface proximal to the end of the tip is between about two-to-one (2:

1) and about one and two-thirds-to-one (1.67;

1) and the inner surface of the inner taper bore extends farther with respect to the length of the probe than the outer surface of the outer taper bore.

18. The soil sampler assembly as recited in claim 13, further comprising a knockout peg assembly configured to eject the soil sample from the soil sampler module onto the conveyor system, wherein the knockout peg assembly is configured to extend a shaft into a tip of the probe.

19. A soil sampler assembly comprising:

a diesel powered power vehicle including a cab;

a soil sampler module coupled to the diesel powered power vehicle, the soil sampler module configured to deposit a soil sample in the cab;

a conveyor system configured to convey the soil sample to the cab, the conveyor system including a central conveyor belt extending longitudinally through the soil sampler module and a lateral conveyor belt extending through the soil sampler module from a side of the soil sampler module to the conveyor belt at an orientation at least substantially perpendicular to the central conveyor belt; and

a sampler arm assembly coupled to the soil sampler module, the sampler arm assembly configured to collect the soil sample.

20. The soil sampler assembly as recited in claim 19, wherein the soil sampler module comprises a power sprocket for powering the conveyor system and a drive sprocket for driving a conveyor of the conveyor system, and a ratio of the power sprocket to the drive sprocket is about two-to-one (2:

1), wherein the sampler arm assembly comprises a drill, wherein the drill comprises a probe configured to obtain a core comprising the soil sample, and wherein the probe comprises a tip including an outer surface defining an outer taper bore and an inner surface defining an inner taper bore, wherein a ratio of an inside diameter of the inner surface distal to the end of the tip to an inside diameter of the inner surface proximal to the end of the tip is between about two-to-one (2;

1) and about one and two-thirds-to-one (1.67;

1).
