Abstract

The invention provides a soil grinding and crushing device and method. The soil grinding and crushing device comprise a feeding funnel, a coarse grinding cylinder, a fine grinding cylinder, a discharging device and a supporting frame which are arranged from top to bottom. The feeding funnel is of an up-and-down through chamfered platform structure, and a first coarse grinding roller and a second coarse grinding roller which are arranged side by side and have parallel axes are arranged in the coarse grinding cylinder. A first fine grinding roller and a second fine grinding roller which are arranged side by side and have parallel axes are arranged in the fine grinding cylinder. The discharging device comprises a first discharging box and a second discharging box which are arranged up and down, a grid screen is arranged at the bottom of the first discharging box, a discharging port is formed in the side surface of the bottom of the second discharging box, the supporting frame is fixed atthe bottom of the discharging device, a motor is mounted on the supporting frame, the motor drives the first coarse grinding roller to move through a first transmission device, and the motor drives the first fine grinding roller to move through a second transmission device. Air-dried soil needs to be ground and crushed before remolded soil samples are prepared in geotechnical tests.

Description

Technical field [0001] The invention relates to the technical field of geotechnical indoor geotechnical tests, in particular to a soil grinding and crushing device and a grinding and crushing method. Background technique [0002] When conducting direct shear, consolidation, unconfined and triaxial tests on remodeled soil samples such as cohesive soil, silt soil, and silt soil, the soil needs to be air-dried and ground and then passed through a certain particle size sieve After that, the soil can be mixed with water for sample preparation. [0003] At present, there is a lack of specialized processing machinery for soil powder grinding treatment. If some existing powder grinding machines used in other fields are used, the soil powder grinding treatment cannot be done well, which will cause some problems, such as grinding accuracy. Uncontrollable, complicated and large machinery, overly complicated operation and not economical enough to use. If some micro grinders are used to grind...
