Abstract
A mobile soil sampling device is mounted on the side of a vehicle such as an ATV or UTV and includes an upstanding frame member which is vertically movable with respect to the vehicle by means of a parallel arm linkage and actuator. A vertically disposed and rotatable auger is mounted on the frame member and is moved upwardly and downwardly with respect thereto through the use of a motor and pinion gear with the pinion gear engaging a gear rack on the frame member. The auger is rotated so as to dig into the ground to the desired depth with the soil sample being conveyed upwardly into a vacuum collection chamber with the soil sample being conveyed to a vacuum chamber mounted on the vehicle. A sample collection device is mounted beneath the vacuum chamber for receiving the desired soil samples. An auger flute cleaning apparatus is mounted on the device to remove soil from the flutes of the auger as the auger is raised from a soil penetration position. The soil removed from the auger by the flute cleaning apparatus drops downwardly into the collection chamber.
