STAND FOR INVESTIGATING UNDERWATER SOIL CUTTING

摘要

The invention relates to the construction and mining and can be used in the stands for the study of the underwater cutting soil. The aim of the invention is to increase the productivity and precision studies. The stand comprises an airtight casing 1 with a ground 10 connected by a conduit 5 with a fluid source. Inside the housing 1 is a rod (SB) 12 for longitudinal movement with the help of the screw shaft 14 with a nut 13. The perpendicular 12 to the axis W is mounted cantilevered arm 17, on the free end of which is fastened symmetrically operating members 21 and 22. A nut 13 threaded binding mechanism linked to a rod 12 via a clutch 23. The working parts 21 and 22 are rotatable together with W 12 about the axis of the latter. For this 12 W mounted in the housing on bearings and provided with a drive 25. At the forward progress W 12 interacts with the soil working member 21, and the reverse - the body 22 is performed in both directions of undisturbed soil cutting, thus eliminating secondary operations to conduct reflux stroke. 2 yl.
