Abstract

This invention relates to earth moving machinery. The goal is to increase machine performance. It includes a running gear with engines 1, working member 2, hydraulic cylinder (HZ) 3 of the drive of working member 2, and pump 5 driven by thrusters 1. Pump 5 is adjustable and has a feed control mechanism consisting of actuating HZ 8, a rod cavity which has a spring 9 and a rod is kinematically connected to the pump 5, from the driver HZ 10 and from the kinematically connected to the HZ 10 rod of the adjusting Bi .HTa 12 and the pointer with the scale 13. The latter is graduated in units of the slope of the bottom of the trench. Piston cavities HZ 8 and 10 are interconnected. A pump valve 5 is connected with a cavity of HZ 3 with a hydraulic valve 4. With a piston cavity of HZ 3 and a hydraulic valve 4, pump 5 is outputted through a non-return valve 6. Rotating screw 12, piston HZ 10 and arrow pointer are lowered to a predetermined slope value controlled by a scale 13. HZ piston 10. Coming down, closes the lower compensation hole and displaces the process fluid in HZ8. The HZ8 rod moves the pump 5 to the position corresponding to the feed required to provide the gradient of the trench bottom as specified on a scale of 13. 1 il.

The invention relates to the earthmoving TiexHHKe, namely, machines for digging grades.

The aim of the invention is to increase the productivity of the trenching machine.

The drawing shows a machine for digging trenches.

The machine for digging trenches includes one part with movers 1, working

the arrow indicator associated with it is lowered to a predetermined slope value controlled on a scale of 13. The piston of the hydraulic cylinder 10, falling down, closes the lower compensation hole and then starts to displace the working fluid into the hydraulic cylinder 8, the rod of which moves the adjustable pump 5 to the position corresponding to the feed required to provide the slope given on a scale of 13

Fgan 2 and hydraulic cylinder 3 of the drive worker 10 bottom of the trench. When the machine is mixed, the body, which is communicated by the piston and rod 5, delivers the specified amount of working

It has cavities with a hydraulic distributor 4. liquid through a check valve 6 in the piston Adjustable pump 5 driven by the moving cavity of the hydraulic cylinder 3, which connectors 1 of the running part are connected to the piston cavity of the hydraulic cylinder 3 of the actuator actuator and with the valve 4, and through the hydraulic valve 7 with a drain. Pump 5 is equipped with a feed control mechanism composed of an actuating hydraulic cylinder.
