Abstract
Abstract A soil sampling device secured to a vehicle for taking soil samples while the vehicle is moving is provided with a housing having a first and second portion. The first portion has a chamber extending outwardly therefrom and the second portion has a soil inlet opening. Soil retaining baffles are disposed within the second portion adjacent the soil inlet opening. The housing is pivotally connected to a mounting bar and brace, which is secured to the vehicle. A hydraulic piston rotates the housing so that the second portion strikes the ground and a small portion of soil is injected into the inlet opening and retained by the soil retaining baffles. The housing is rotated and the captured soil is directed to the chamber whereupon the soil sampler is in position to take another soil sample.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
140 words
A soil sampling device secured to a vehicle for taking soil samples while the vehicle is moving, comprising: a housing having a first and a second portions in open communication with each other, said second portion having a soil inlet means therein; soil retaining means disposed within said second portion adjacent said soil inlet means; a chamber extending outwardly from said first portion and in communication therewith; baffle means interposed between said chamber and said first portion and extending across one end of said chamber; mounting means attached to the vehicle; and means secured between said mounting means and said housing for selectively rotating said housing between an upright and an inverted positions, whereby when said housing is rotated to an upright position said second portion strikes the ground and soil inters said soil inlet means for capturing said soil.
Claim 2
Dependent Claim
140 words
A soil sampling device secured to a vehicle for taking soil samples while the vehicle is moving, comprising: a housing having a first and a second portions in open communication with each other, said second portion having a soil inlet means therein; soil retaining means disposed within said second portion adjacent said soil inlet means; a chamber extending outwardly from said first portion and in communication therewith; baffle means interposed between said chamber and said first portion and extending across one end of said chamber; mounting means attached to the vehicle; and means secured between said mounting means and said housing for selectively rotating said housing between an upright and an inverted positions, whereby when said housing is rotated to an upright position said second portion strikes the ground and soil inters said soil inlet means for capturing said soil.
