Abstract

The subject of the application is a device for digging trenches, which may be a drainage canal, a path for laying electric cables, optical fibers, etc. The device for digging trenches comprising a support frame (12), a cutting disc (1) with a hemispherical cover (16) and with cutting knives (3, 4) arranged around it on the circumference at equal intervals, an actuator (5) for lifting and lowering parts of the support frame (12) is characterized in that it has a sliding skid (6), the front part of which is pivotally mounted to the bracket, and the rear part is pivotally mounted to the guide mounting (15) and the actuator (5). The guide (15) consists of two closed profiles, an outer and an inner profile placed therein, which is extended or retracted by means of a hydraulic actuator (5). The supporting frame (12) has two lower hooks (8) and one upper hook (1), which is connected to it via a connecting element (9), and the supporting frame (12) has reinforcement in the form of a support (11).The device is equipped with two support feet: rear (6) and front (7).
