FIELD: construction industry.
SUBSTANCE: invention refers to the field of construction mechanisation and may be used for trenches excavation for strip foundation upon individual housing construction. Device for trenches excavation contains towing machine, screw unit connected to towing machine power-takeoff shaft and installed to be enabled to change inclination to ground surface to 45°, ball joint, dipper assembly. Device is provided with single-axle trailer with tank for balance weight which is connected to towing machine by rods fixed correspondingly on single-axle trailer by shackles, and on towing machine - by double shackles with holes of oval form which minor diametre is equal to diametre of link pin. At that rods are reinforced by stiffeners of triangular form. Dipper assembly are arranged at an angle to each other, movably attached to rods and are enabled for movement in vertical plane by means of control columns. On the part of trailer dipper assembly are reinforced by beam. Screw unit is connected to towing machine power-takeoff shaft via Hooke clutch and is connected to single-axle trailer by means of ball joint installed on screw and telescopic hydraulic cylinder-limit stop.
EFFECT: simplification of device for trenches excavation.
