Lever type soil-sampling ring cutter device

Abstract

The invention relates to a lever type soil-sampling ring cutter device. A separable lever device is added on a soil-sampling ring cutter and comprises a movable handle and a supporting column, wherein the supporting column is vertical to the base and is fixedly connected with the base; the movable handle is positioned at the upper part of the supporting column and is movably connected with the supporting column by a bolt; a sleeve capable of sliding along the movable handle is arranged at the middle position of the movable handle; a movable bolt on the sleeve is connected with a force applying rod; and a ring cutter is arranged under a pressure applying plate. When in soil sampling, a soil sample is arranged on the base of the ring cutter device, then an edge of the ring cutter is downwards arranged on the soil sample, the handle is pulled upwards to enable the pressure applying plate to be just arranged on the ring cutter, the movable handle is pulled downwards by force to enable the pressure applying plate to apply pressure uniformly on the ring cutter, so that the ring cutter enters the soil sample. The lever type soil-sampling ring cutter device provided in the invention has the advantages that by the improvement on the ring cutter, the common manual pressing mode can be used, the ring cutter can be smoothly pressed into the hard soil sample for sampling; in the whole sampling process, the force applying is uniform, and the efficiency and the quality of sampling are improved.

Description

technical field [0001] The invention relates to the field of civil engineering sampling tools, in particular to a soil-taking ring knife device. Background technique [0002] The ring knife is a kind of test equipment used for soil engineering tests. It is mainly used to prepare soil samples for testing such as soil density and water content. A ring knife is essentially a rigid, open-ended cylindrical sleeve with a sharper edge at one end. In specific use, a relatively large soil sample is prepared first, and then the ring knife is placed on the soil sample, the cutting edge is in contact with the surface of the sample, and then pressed down firmly to make the ring knife enter the soil sample. In the process of forcing the knife changer to move downward, the blade of the ring knife cuts into the surrounding soil samples. When the ring knife completely enters and penetrates the soil sample layer, the soil sample in the ring knife is taken out to make a complete sample. soil...

Problems solved by technology

In the traditional experiment, the ring knife is pressed down into the soil sample by manual direct pressing. However, if the soil is hard, it is difficult to manually press the ring knife into the sample.
