ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a soil sampler.
While the invention is referred to as a soft soil sampler, it will be appreciated that the device can be used to obtain samples of hard, compacted or frozen ground such as permafrost, or samples of a variety of other materials such as peat, muskeg and shale. Accordingly, the term “soil”, as used herein, should be given a broad interpretation.
2. Discussion of the Prior Art
Soil or core samplers are by no means new. Examples of such devices are disclosed by U.S. Pat. No. 2,701,121 issued to A. D. Bull on Feb. 1, 1955; U.S. Pat. No. 2,709,368, issued to D. E. Wolpert on May 1, 1955; U.S. Pat. No. 2,868,019, issued to A. D. Bull on Jan. 13, 1959; U.S. Pat. No. 3,817,334, issued to Henry Bolt on Jun. 18, 1974; U.S. Pat. No. 4,191,263, issued to T. J. Malterer on Mar. 4, 1980; U.S. Pat. No. 4,316,393, issued to H. Philipenko on Feb. 23, 1982; U.S. Pat. No. 4,333,541, issued to J. G. Doty on Jun. 8, 1982; U.S. Pat. No. 4,482,021, issued to Roman Repski on Nov. 13, 1984; U.S. Pat. No. 5,213,169, issued to M. E. Heller on May 25, 1993; U.S. Pat. No. 5,394,949, issued to N. A. Wright et al on Mar. 7, 1995 and 5,435,399, issued to G. G. Peterson et al on Jul. 25, 1995. In general, the patented devices are somewhat complicated, and often cumbersome and consequently can be used on a truck or other large vehicle only.
Accordingly, a need still exists for a soil sampler which can be used on a variety of vehicles, including small trucks, trailers or all terrain vehicles.
GENERAL DESCRIPTION OF THE INVENTION
An object of the present invention is to meet the above defined need by providing a relatively simple, lightweight soil sampler, which can be mounted on a variety of vehicles.
Another object of the invention is to provide a soil sampler constructed of a few, structurally simple components which are easy to assemble and to operate.
Accordingly, the invention relates to a soil sampler comprising an elongated mast; a carrier for mounting the mast on a vehicle; a carriage slidable on said mast; a hammer on said carriage for movement with said carriage; a core tube slidable on said carriage beneath said hammer, whereby, when the carriage is moved downwardly to a position in which the core tube engages the ground, continued downward movement of the carriage brings the hammer into engagement with the core tube and actuation of said hammer drives the core tube into the ground; a winch on said mast; and a cable connecting said winch to a top end of said carriage for moving said carriage upwardly to draw the core tube from the ground.
