(54) BUCKET EXCAVATOR-DRAGLINE

one

The invention relates to earthmoving machines and, in particular, to single-bucket excavator draglines.

Known working body excavatordragline, including a bucket, open in front and connected with. hauling, lifting and tilting ropes 1.

However, such working bodies do not work efficiently enough, since a significant part of the soil gathered into the bucket when digging, pours out of the bucket when it is raised up and transported.

Also known is a dragline excavator bucket containing side walls, the bottom with a knife, an arch and a damper with a roller on it fixed by means of levers, a suspension, cocTOsniryio from hauling, tipping and lifting ropes, as well as a damper control rope connected to the lifting rope 2.

However, a known working body does not work well on dry and wet soils, since the track roller buries

In loose soil or sticky on sticky wet soils and therefore the resistance to digging the soil increases dramatically. In addition, in order to increase the effort to close the flap, the latter should have considerable weight.

The purpose of the invention is to increase productivity and reduce weight.

The goal is achieved by the fact that in a bucket of a dragline, including

10 side walls, a bottom with a knife, an arch, a flap connected by an axis to the front part of the walls, and by means of a control cable — to a hoisting cable, hauling and tilting ropes, an arch

15, the bucket is equipped with blocks, and the flap walls on opposite sides of the axis have levers, some of which are connected to a cable and others with a tipping cable that bends around

20 arches.

Claims (2)

At the same time, the levers connected to the traction rope are adjustable. holes. 3 In FIG. 1 shows an excavator bucket of a dragline, side view; in fig. 2 - the same, the process of transportation and unloading, the bucket contains side walls 1, as well as a knife 2, an arch 3, a flap 4 and walls 5, pivotally mounted and the front of the side walls 1 of the bucket using axles 6, the flap has an eye 7 with a rope 8 of the flap control, which is fastened with the other end to the tipping block 9. The latter is mounted on the hoisting rope 10 which is fixed in the lugs 11 of the side walls 1 of the bucket. T 1-star rope .12 is fixed on the lever 13 of shorter length, and the tilting rope 14 bends around the tilting block 9 (on the lifting rope 10) and blocks 15 on the arch of the bucket 3 and is connected to the arms of the levers 16 more length. The smaller arms of the arms have a number of holes 17 for shifting the draft rope 12 when operating on different soils. The work of the dragline excavator is as follows. When Konainra soil lifting 10 and tipping 11 ropes are weakened, the bucket moves along the bottom of the bottom using a traction rope 12. In this case, the knife 2 cuts off the chips of the rope that enters the gap between the knife 2 and the lower edge of the valve 4, which is formed by turning the valve 4 clockwise under the action of the cable 12, the rotation of the valve 4 proceeds until the holes 17 and the axis 6 are located along the line of action of the rope 12. After the bucket is filled, it occurs. tension lifting of the Sh1y 1O and tilting 14 ropes. The latter acts on the levers 16 and turns them and the flaps 4 counterclockwise until its lower edge comes in contact with the knife 2, cutting off the bucket in the front part from requesting the ground. This rotation ensures that the length of the tipping rope 14 greater than 1.5-2 times the length of the arms of the arms 13 of the fastening of the rope 12, After closing the valve 14, raising the bucket with the rope 10 into the transport position is carried out in the usual way. When unloading the ground, the cable 12 is weakened As a result, the tipping cable 14 and the bucket is tipped down by the knife 2. In this case, the tilting gate 4 is held by the control cable 8, and a large gap is formed between its lower edge and the knife 2, which ensures free flow of soil from the bucket. The invention increases the efficiency of the excavator on dry and wet soils, since in the working organ the flap is lifted by a rope and its closure is tilted, which eliminates the additional support roller and reduces the weight of the flap. Claims 1. Dragline excavator bucket, incl. Tea side walls, knife bottom, arch, damper connected with the axle to the front part of the walls, and control cable with a lifting rope, traction and tipping rope, characterized in that in order to increase productivity and reduce weight, the bucket arch is provided with blocks, and the flap walls on opposite sides of the axis have ridges, some of which are connected to the cable and others to the tipping cable that bends around the arch blocks, 2 Bucket, n, 1 , about tl and ch and y and also with the fact that levers, connected to the cable, they have adjustment holes.
