The present invention relates to the field of soil sampling, and more particularly, to a soil sample collection device, comprising : a housing provided with an inner cavity; A drill rod arranged in the inner cavity in a penetrating manner, wherein one end of the drill rod is a sampling end, and the sampling end can extend out of the first end of the shell; A first hydraulic cylinder including a first piston, wherein the first piston reciprocates to drive the drill rod to rotate around its axis and move toward the first end of the housing; A second hydraulic cylinder provided with a second piston, a first end of the second hydraulic cylinder being provided with a manual device driving the second piston to reciprocate; The first end of the first hydraulic cylinder is communicated with the second end of the second hydraulic cylinder through the fluid flow channel, and the diameter of the second piston is larger than that of the first piston, so that the technical problem that manual operation of the soil collecting device is laborious and inconvenient is solved.
