Abstract
A sampling head for a vehicle mounted mechanized soil sample collecting unit includes an auger mounted at one end of a drive shaft supported on a positioning arm on the vehicle. The drive shaft is connected to an auger head which is driven into the soil. A linear power source, such as a hydraulic cylinder is used to provide vertical force to drive the auger head into the soil. A separate rotational power source is used to rotate the drive shaft and auger head. The soil from the drilling process is collected in a receptacle and can be transferred into a separate container for soil analysis.
Claims15
a soil sampling head for use on a mechanized soil sampling device such that the sampling head is positioned on the soil for collecting a soil sample, said head comprising:
- a receptacle positioned on the soil;
- an auger vertically aligned and adapted to be selectively advanced through the receptacle and into the soil for drawing soil upwardly into said receptacle;
- a drive shaft vertically aligned with and connected to an upper end of the auger;
- a linear power source connected to said drive shaft for forcing said auger into the soil;
- and
- a rotating power source connected to said drive shaft for simultaneously rotating said auger, said rotating power source remaining stationary relative to the linear movement imparted to said drive shaft by said linear power source, whereby driving said auger into the soil and withdrawing the auger from the soil deposits a sample of soil in the receptacle.

- a linear power source connected to said drive shaft for forcing said auger into the soil said drive shaft defining a longitudinal axis;
- and
- a rotating power source connected to said drive shaft for simultaneously rotating said auger, said rotating power source having an output shaft defining a longitudinal axis which is offset from the longitudinal axis of said drive shaft, whereby driving said auger into the soil and withdrawing the auger from the soil deposits a sample of soil in the receptacle.
