The utility model relates to the technical field of soil sampling devices, in particular to an efficient
cutting ring soil sampling device. According to the technical scheme, the device comprises a fixed sleeve, a knock-down hammer is movably sleeved with the fixed sleeve, the upper end of the knock-down hammer is fixedly connected with a connecting rod, and the upper end of the connecting rod penetrates through the fixed sleeve and extends to be connected with double handles; the first spring sleeves the outer wall of the connecting rod, the lower end of the first spring is fixedly connected with the knock-down hammer, and a limiting
assembly for adjusting the elasticity of the first spring is arranged at the upper end of the fixed sleeve; the fixed cylinder is fixedly arranged at the lower end of the fixed sleeve, and a
cutting ring for sampling soil is arranged in the fixed cylinder in a sliding manner. According to the utility model, the
cutting ring is knocked into soil by utilizing the
free falling motion of the knock-down hammer and converting
gravitational potential energy into
kinetic energy, so that compared with direct manual pressing, the labor cost is greatly saved, and the soil sampling efficiency is improved.
