Abstract

Use: development of gounds in underwater slaughter. The device includes a cutter with a support ring and a drive shaft. The suction pipe is made with a slit-shaped tip. The latter has an orifice, which is blocked by two elements. Top and bottom walls of the tip are made congruent. The tip elements form its side walls, each element is made in a semi-ellipse and telescopically connected to the upper and lower walls, 9, or „

Description

 The invention relates to hydraulic construction and is intended for the development of soils in the underwater bottom.

The purpose of the invention is to increase the efficiency of the development of the soil by reducing the pressure loss when the soil enters the mouth of the tip.
