Abstract
The patent of the invention discloses an automatic soil density measurer based on a cutting-ring method. The automatic soil density measurer specifically comprises a table body, wherein the table body is in a cuboid square column shape integrally; an overhanging beam, which is overhung and suspended, is arranged on the top surface of the table body; and a rotatable base is arranged at the bottom of the table body. A cylindrical electromagnet, which moves up and down, is arranged at the end part of the overhanging and suspended square beam and a steel-made cutting ring is adsorbed at the lower part of the electromagnet. A detachable working table is arranged under the cutting ring and is divided into two parts; a detachable scraping knife is arranged on the working table on the outer side; a round hole is drilled in the center of the working table; and a weighing device is arranged under the round hole. Compared with a traditional soil density measurer with a cutting-ring method, the automatic soil density measurer has relatively great advantages that all experiment instruments of soil density measurement are highly integrated and thus are prevented from losing and missing; a field test can be carried out and errors caused by the fact that operation of field technical staff is improper when soil density is determined are avoided; and the automatic soil density measurer provides a reliable way for rapidly measuring the density of a lot of soil samples.
