Ditchless drainlayer

摘要

A ditchless drainlayer comprising a frame mounting a cutter-type working element for laying drainpipes. It is provided with a hydraulic cylinder for changing its angular position and a transmitter of its angular position with an amplifier-converter. Also, a device for controlling the height of the working element made as a support connected to said working element, swivels around the horizontal transverse axis and is provided with a cylinder for turning said support. The swivelling support is connected by its turning cylinder and by an additional amplifier-converter with a transmitter of the height of the working element installed on said element. The support is shaped as blades diverging in both directions from the working element, and said blades are rigidly attached to the connecting link which is articulated to the working element by two rods arranged one above the other, whose extensions converge in front of the machine as it goes, while the transmitter of the angular position of the working element is connected by its own amplifier-converter with the hydraulic cylinder intended to change the angular position of the working element.
