Description

five

The invention relates to earthmoving machines, and more specifically to single-bucket excavators with devices for controlling the depth of digging.

The purpose of the invention is to simplify the design.

FIG. 1 shows a device for controlling the depth of digging; side view; in fig. 2 - the same view in nlan.

The device consists of a tank 3 10 with liquid rigidly fixed on the excavator 2 from a tank 3 of a lever 5 pivotally mounted on the top cover 4 of the tank 3, the lower end 6 of which has a counterweight 7 located in the tank 3 with the fluid. The upper end 8 of the lever 5 is rigidly connected

trench digging depth on the hands1) / 1P :. 1 k) c-pt device for control: 1I deaf digging. In this case, the capacitance 3 is rigidly fixed to the angle 1 so that the horizontal uiTpnx 11 of the receiving mirror 10 coincides with a given digging depth h increased by the distance from the copier cable 12 to the ground surface, equal to Hb. Then, along the future trench, the G2 cable is installed at hi from nova soil.

Trenching is done in the usual way. The digging depth is controlled by means of a guide mirror 13, when approximately 0.5-1.0 m remains to the design bottom of the trench and a reflected image appears in the guide mirror 13 by a housing 9 that has windows. In one is the circumference of the copier rope 12. For control, the receiving mirror 10c of the digging depth of the handle 1 of the excavator 2 is not mounted.

with a horizontal stroke of 1 1, oriented to the vertical position,

in the direction of the copier rope 12, and in the other, the deepening of the bottom of the trench is done to

with the possibility of changing the inclination and fixed reflected images of the horizontal section in the vertical plane and the orientation line 1, the rod 15 and the copier rope 12.

in the direction of the cab 14 of the excavator 2. Since the housing with mirrors is connected

Harned with counterweight, it occupies a vertical position, which provides the necessary accuracy in determining the depth of digging.

The guide mirror 13 is tilted in such a way that it provides sight

Located opposite the receiving mirror 10, the window of the housing 9 has a horizontal rod 15 fixed opposite the horizontal tip 11.

The device works as follows.

On the excavator arm, starting from the teeth of the shovel, divisions are made that determine the depth of digging. In accordance with a given
