SU1283304A1 - Scraper bucket - Google Patents

Abstract

The invention relates to a land-lift technique and increases productivity by reducing the resistance of the bucket to filling with soil. For this, the main bottom of the bucket consists of a rear fixed part 6 and a front pivotally controlled (BEAM) 7 with a steering hinge (FB) 8 o The FB 8 is located in the plane of the main bottom. The BEAM 7 has a primary 14 and an additional 15 cutting knives. The lobov surface of the additional cutting knife 15 is matched to the underside of the BEAM 7. When the BEAM 7 device is operated, it works as the bottom. Simultaneously with turning up the additional bottom 4, the bucket 1 is lowered. Knife 14 PUCH 7 goes deep into the ground. When filling the half of the BUC 7 bucket with the help of hydraulic cylinders 10 through the WB 8 and the levers 9 rotates, moves the soil to the back of the bucket and places it on the fixed part 6 of the bottom. As the bucket 7 is filled with soil, the BEAM 7 rises and becomes an intermediate wall. The soil is transported to the place of discharge. 7 il. (L with:

The invention relates to a earthmoving machinery, specifically to scrapers, intended for cutting layers of the soil, filling it with a bucket, transporting it and layer-by-layer dumping.

The purpose of the invention is to increase productivity by reducing the resistance of the bucket to the soil.

Figure 1 shows the scraper bucket in the transport position without soil, figure 2 - the same, when filling the back of the soil with the ground; fig.Z-the same, when filling the front; figure 4 - transportation of soil scraper; figure 5 and 6 - unloading of the soil; figure 7 - section aa in figure 4.

The scraper's bucket 1 includes side walls 2 having hinges 3, on which an additional bottom plate 4 with a 5-turn actuator is rotatably controlled. Between the side walls 2 there is a main bottom, consisting of the rear fixed part 6 and the front pivoting part 7, made in the form of a blade and rigidly fixed on the axis of the hinge 8. On the same axis, on the outside of the side walls 2, the front pivot arm is rigidly mounted parts and hydraulic cylinders 10. The bucket has a retractable rear wall 11 with a hydraulic cylinder 12 mounted on the bumper 13. The front pivoting part 7 of the bottom is equipped with cutting - the main 14 and additional 15. The fixed part of the bottom is equipped with a stop 16.

actively moving the soil to the back of the bucket and placing it on the non-moving part of the 6 bottom. At the same time, the additional bottom 4 is positioned in a position to set the soil in the front part of the bucket (Fig. 3). The soil is cut by the knife 15 and lifted along the dump surface of the rotary part of the bottom, filling the front part of the bucket. As the front part of the bucket is filled by turning the additional bottom 4, the loading slot completely overlaps and the soil is transported (Fig. 4) to the place of unloading. The unloading is carried out by rotating the additional bottom 4, from which the soil is poured into the formed gap. The layout is made with a knife 15. Then, as far as unloading the front part of the bucket, the rotary part 7 of the bottom is brought into a horizontal position (up to the stop 16), aligning it with the fixed rear part 6 of the bottom (Fig.6) and extending by means of hydraulic cylinders 12 of the rear wall 11 pushes the primer out of the back of the bucket, which is planned with a knife 14.

Invention Formula The scraper bucket, which includes side and rear sliding walls, a main bottom with a front cutting knife, located in front of the main pivotally controlled additional bottom and a front wall, characterized in that Bucket scraper works as follows. At the beginning of the junc- tion (Fig.), Simultaneously with the additional bottom 4 turning upwards, the bucket 1 is lowered, at this time the knife 14 of the rotary part 7 of the bottom deepens into the ground, which fills the rear part of the bucket. When half of the bucket is filled, the turning part of the bottom with the help of hydraulic cylinders 10 through the hinge 8 and the levers 9 rotates, thereby raising In order to maintain performance by reducing the bucket primer filling resistance, the main bucket bottom is made from the rear fixed part and the front rotatable part with the hinge pointing, located in the plane of the main bottom, which has an additional cutting knife fixed on the rear edge of its front part, at the same time, the frontal surface of the additional cutting knife matches the underside of the latter. / 7 P P 7 9 8.1516 S 6 Fiz.2 in s // 72 73 qtyuff. / (UUL /// PG / / 777 777/7777 7777 777/7 //// / L // // // // // // V //// G5J6 6 .6 Js jL VNIIPI Order 7387/25 Circulation 606 Polygr. pr-tie, Uzhgorod, st.
