TRENCHER Russian patent published in 2022 - IPC E02F3/08 E02F5/06 

FIELD: earthmoving machines.

SUBSTANCE: invention relates to earthmoving equipment and can be used for digging trenches in soils with various properties. The trencher contains the base machine and working equipment, which includes cutting, raking and dump conveying bodies mounted on a frame connected to the base machine pivotally. The trencher is equipped with a hydraulic distributor for lifting working equipment, an adjustable hydraulic throttle and a support roller in the rear of the frame. The cutting body is made in the form of cutters with cutting teeth arranged along a helical line and with the possibility of synchronous rotation in opposite directions. The hydraulic distributor is connected in one of the positions of the spool by a hydraulic line, through an adjustable hydraulic throttle, with the stem cavity of the hydraulic cylinder, the hydraulic motor control, the drive of the running equipment of the base machine. A spring and a mechanism for regulating its elastic force are installed in the piston cavity of the hydraulic cylinder.

EFFECT: increase in reliability by simplifying the kinematic scheme and increasing productivity by automating workflow management.
