The invention relates to construction and is intended for excavating EKN trenches in the ground during the construction of waterproof curtains and underground weapons using the wall in the soil method. I The aim of the invention is to reduce the power consumption of the device.

FIG. I presents the device for the penetration of trenches in the ground, common Ivd; in fig. 2 is a section A-A in FIG. 1 ta of FIG. 3 shows a section BB in FIG. one.

The device includes a chassis trolley 1 with a drive 2, on which an axis 4 of the hinge is placed in under the hips. On axis 4 of the hinge, gear 5 is fixed coaxially with it, and an electronic actuator 6 is attached. With gear 5, rails 7 of the mechanical displacement, fixed on the upper tube 8 of the air-lift rod and fixed axle 9 with the actuator 10 in, are kinematically connected. | rascheni. The upper 8 airlift pipe is installed in the 1I supports with axle axial longitudinal displacement, and the cutting rods c) are installed in them with the Esenz 12 gauge, equipped with the option of a Tseni, the lower 13 airlift tube is fitted coaxially with the upper 8 sec the possibility of axial displacement relative to each other and ajecTKO is associated with the support 1 1,

Erlift becoming from the top 8 and bottom 13 pipes and the support | 1} connected with it. The unit of the rods is formed by the working organ of the device.

Device for trenching BJ soil works as follows.

The cutting rods, rotated by the drive 10, by the cutters 12, destroy the ground Hia bottom 14. To cover the entire height, the cutting rods are moved up and down with an amplitude not less than the distance between adjacent cutters. Such movements are carried out by means of an actuator 6, which provides a reciprocating motion of the gear 5 mounted on the axis 14 of the hinge. The reciprocating motion of the gear 5 is converted into a reciprocating movement of the upper pipe 8 of the air-lift stand and cutting rod block 9 kinematically associated with it. At the same time, the displacement of the upper pipe 8 of the lift rod and the cutting rod block 9 is carried out in opposite directions their mass, reducing energy consumption during operation of the device. The greatest compensation, and consequently, energy savings, is achieved when the ratio of the mass of the upper tube 8 of the airlift to the mass of the block of the cutting rods with the lower tube of the 13 airlift of stav is equal to one. The lower pipe of the air-lift stavil is moved together with the block of the cutting rods 9, - ensuring the selection of destructible soil in the zone of its most intensive discharge. Moving the trolley J with the drive 2, the continuous trench is sinking.

Invention Formula 1 A device for driving trenches in the ground, including a undercarriage, an operating member hinged on the undercarriage consisting of an air-lift stand with holders and a block of cutting rods installed in the holders, and a mechanism for displacing the operating member mounted on the hinge axis, characterized in that. In order to reduce the power consumption of the device, the air-lift device is made of two coaxially mounted with the possibility of moving the upper and lower tubes relative to each other, and the mechanism is not. movement is made in the form of a gear mounted on the hinge axis, and kinematically connected racks with it, secured on the cutting shaft block and the upper tube of the air-lift rod, 146 . u 14655264 Thereby, the upper pipe of the air-lift stavion is mounted in the cage with the possibility of axial movement, and the lower pipe of the air-lift rod is rigidly connected to the cage. 2. The device according to claim 1, about t l. and - it is so that the mass ratio of the upper pipe of the air-lift stav and the block of the cutting rods with the lower pipe of the air-lift stav is equal to one. .S bb
