Full-automatic rotating soil cutter and utilization method thereof

Abstract

The invention belongs to the field of geotechnical engineering triaxial test soil sample preparation devices and relates to a full-automatic rotating soil cutter and a utilization method thereof. Thefull-automatic rotating soil cutter comprises a mounting frame, a drive gear column, a threaded rod, a first driven gear disc, a soil cutting knife, an upper fixing plate mounting shaft and a lower fixing plate mounting shaft. The mounting frame comprises an upper mounting plate and a lower mounting plate, and the upper mounting plate and the lower mounting plate are in opposite arrangement; the drive gear column is arranged between the upper mounting plate and the lower mounting plate and can be driven to rotate by an external driving mechanism; one end of the threaded rod is mounted on the upper mounting plate while the center of the other end of the threaded rod is provided with a through hole; the first driven gear disc is in transmission connection with the drive gear column; the soilcutting knife is mounted on the lower surface of the first driven gear disc; the upper fixing plate mounting shaft is mounted on the upper mounting plate while an upper fixing plate is mounted at theother end of the upper mounting plate; one end of the lower fixing plate mounting shaft is mounted on the lower mounting plate while a lower fixing plate is mounted at the other end of the lower fixing plate mounting shaft. Soil disturbance and damages in soil sample preparation can be avoided.

Description

technical field [0001] The invention belongs to the field of soil sample preparation devices for triaxial tests of geotechnical engineering, and relates to a fully automatic rotary soil cutter and a using method thereof, which are suitable for clay, grass charcoal and loamy sandy soil. Background technique [0002] At present, the application of this device in many geotechnical projects is becoming more and more mature. At this time, people pay more attention to the guarantee of its accuracy and the maintenance of the original structure and state of the soil. In the prior art, the cutting structure of the soil sample is relatively simple, the work efficiency is low, the precision error is large, the effect is not ideal, and the limitation of the requirements for the soil sample is relatively large. A ring-knife soil cutter disclosed in Chinese patent CN206710168U includes a handle and a soil cutter housing fixed at the lower end of the handle. An outer edge cover extends ou...

Problems solved by technology

And when the existing soil cutter cuts the soil sample along the leaning plate, the soil body to be cut off on the predetermined sample is easy to bring down the soil body on the final soil sample, especially the bottom of the soil sample is prone to soil caving, if the soil sample If the bottom of the soil collapses or is seriously disturbed, the soil sample cannot be used or seriously affects the experimental results.
