Description

(54) MACHINE FOR DEVELOPMENT OF SOIL

one

The invention relates to earthmoving machines and can be used to develop and move soil in excavation and construction works, digging canals, trenches and mining minerals with a large amount of earthworks.

A known machine for developing a trench, for example a dragline, consisting of a chassis with a cargo boom, a bucket, driven by a cargo and haul rope Cl.

The disadvantage of this machine is the complexity of the constructive execution of the pivot platform, the placement of booms, counterweight, traction winches and other equipment on it, which creates a large area of kinematic elements moving into spatial space, which consumes a relatively large amount of electricity.

A known machine for the development of a tire containing a chassis with a working equipment of a dragline having a boom rope and a bucket 2 associated with it.

The disadvantage of this machine is its idle cycles with an empty bucket, which leads to a decrease in productivity as well as impossible. to increase the width of the operated exit due to the restriction of the boom.

The purpose of the invention is to increase the productivity and the width of the penetration being worked.

The goal is achieved

0 in that the excavation machine containing the undercarriage with the working equipment of a dragline having an arrow, the haul rope and the bucket I associated with it are provided with an additional

5 running gear with dragline working equipment having an arrow, a haul rope and a bucket connected to it, with the buckets interconnected. In addition, the buckets are connected

0 articulated.

FIG. 1 shows a machine, a general view of FIG. 2 - the same top view.

The machine includes running gears 1 and 2, on which booms 3 and 4 are installed, counterweights 5 and 6, traction winches 7 and 8 with traction ropes 9 and 10, and buckets 11 and 12 connected by a hinge 13.

The machine works as follows

The buckets 11 and 12, moving with the help of the traction winch 8 and the ropes 9 and 10, are loaded with soil, cutting or assembling the latter. Winch 7 is braked, ropes 9 and 10 are tightened and buckets 11 and 12 are torn from the ground.

Further, the bucket under the action of force: the metal in the hinge 13 is folded and, in this form, is transported to the place of unloading without spillage. When the bucket approaches the place of unloading, the winch 7 is disengaged, the ropes 9 are loosened, the bucket overturns and the rock is poured into the dump. After unloading, the bucket using the winch 7 moves in the direction of the machine 1, and the cycle is repeated.

The width and depth of the array under development is regulated by the distance between the running gears of the machine.

The use of the proposed invention allows excavation of minerals from deep pits, build canals, dams, conduct stripping works with a large amount of earthworks with a relatively high productivity and low energy consumption.
