摘要: An automated soil sampler is removably mounted on an agricultural tractor and collects soil samples in a farm field while the tractor is driven through the field. At a periodic interval, the soil sampler momentarily lowers a soil collection knife into the soil to collect a soil sample, raises the collection knife out of the soil, and transfers the collected soil sample into a bar-coded storage container. The GPS location of the soil sample is associated with the storage container's bar-code in a data file. The interval between successive periodic soil samples corresponds to a determined forward displacement of the tractor. Storage containers that have received soil samples are moved to a storage area until all of the soil samples for a given field have been collected.

摘要: An automatic soil sampler for taking samples of topsoil has a soil breakdown assembly that cuts a shallow furrow in the soil and moves debris to the side. Soil is collected with a sampling knife having a series of empty chambers adapted to receive samples of topsoil. A rotating discus is disposed opposite the soil sampling empty chambers for urging soil into the soil sampling empty chambers. A cup carrousel carries empty identified cups for receiving soil samples. A delivery assembly places one of the empty identified cup in a cup receiving station. A filling assembly connects the knife chambers carrying collected soil samples with the cup receiving station. The cups are filled with soil samples in a collecting station. Each filled cup has its identifier sent to memory along with the location at which the sample was taken.
