(54) СКРЕПЕРНЫЙ ПОЕЗД(54) NUCLEAR TRAIN

Изобретение относитс к землеройнотранспортным машинам, в частности к скреперам .The invention relates to earthmoving machinery, in particular scrapers.

Известен двухишлевой KOBLU скрепера, св занный с т говой рамой на ходовой части 1.A two-pointed KOBLU scraper is known, associated with a traction frame on running gear 1.

В таком ковше выполнение в дниш,е двух щелей лТ,л прохождени грунта св зано с повышением емкости ковша н снижением трени в грунте при его загрузке.In such a bucket, the execution in the bottom, e of the two slots LT, l of soil penetration is associated with an increase in the capacity of the bucket and a decrease in friction in the soil when it is loaded.

Наиболее близким к изобретению вл етс скреперный поезд, содержащий т гач св занную с ним раму на ходовой части, к которой прикреплены ковши 1i гидроцилиндры их поворота 2.Closest to the invention is a scraper train containing a pull-out frame associated with it a frame on the undercarriage to which the buckets 1i are attached are the hydraulic cylinders of their turn 2.

В поезде используютс два т гача, что ограничивает емкость ковша, сцепл емого с одним из т гачей.The train uses two tons of gacha, which limits the capacity of the bucket that is engaged with one of the tons of gachets.

Целью изобретени вл етс повышение эффективности разработки грунта и его перемещени путем увеличени емкости скреперного поезда. The aim of the invention is to increase the efficiency of excavation and its movement by increasing the capacity of the scraper train.

Это достигаетс тем, что рама снабжена жестко прикрепленными к ней и вертикально установленными кронп1тейнами, на которых подвешены ковши, шариирно св занныеThis is achieved by the fact that the frame is provided with rigidly attached to it and vertically mounted crown, on which buckets are hung, which are sariirno connected

посредством поворотных рычагов один с другим , при этом рама выполнена П-образной, к верхней части которой прикреплены кронштейны и гидроцилиндры поворота ковшей, шарнирно св занные с периферийными част ми переднего и заднего ковшей, а нижние концы рамы св заны с ходовой частью и между ними установлены ковши.by means of pivoting levers with one another, the frame being made U-shaped, to the upper part of which are attached the brackets and hydraulic cylinders for turning the buckets, hingedly connected to the peripheral parts of the front and rear buckets, and the lower ends of the frame are connected to the chassis and between them buckets are installed.

На фиг. 1 изображен скреперный поезд, общий вид; иа фиг. 2 - то же, вид сверху; на фиг. 3 - сцепное устройство ковшей; на фиг. 4 - скреперный поезд, рабочее положение .FIG. 1 shows a scraper train, general view; FIG. 2 - the same, top view; in fig. 3 - bucket hitch; in fig. 4 - scraper train, working position.

Claims

The scraper train includes a torque gauge 1, the thrust force of which is transmitted through the towing bracket 2 and the drawbar 3 to the U-shaped frame 4 supported by the front 5 and rear 6 axles of the chassis 7. On the frame 4 are vertically mounted brackets 8, on which using the hinges 9, the buckets 10 are swiveled with the possibility of their rotation (forward and backward) relative to the hinge 9. Each bucket 10 includes the front flap 11, the rear movable wall 12, which is extended and retracted by double-acting hydraulic cylinders 13. At the bottom of the bucket 1 0 there are front 4 and rear 15 cutting edges. The buckets 10 are connected to each other by means of a pulling frame 16, levers 17 and a coupling device 18. The tempered frame 16 is connected rigidly with a hinge 9 to the bucket 10. The buckets 10 are controlled by two front hydraulic cylinders 20 that turn the buckets and two rear hydraulic cylinders 21 The hitch device 18 consists of a pull rod 22 fixed with the help of angles 23 and plates 24 in the rear part of the bucket 10. On the slide 22 a slider 25 is mounted with a hinge 26 for fastening the lever 17 of the rear bucket 10. On both sides of the slider 25 there are damping springs 27 with krychshkam 28. Scraper train operates as follows. When the front 20 and rear 21 hydraulic cylinders are turned on, by supplying the working fluid to the overpressure cavities, the force developed by the hydraulic cylinders 20 and 21 is transferred to the buckets 10, which are rotated relative to the hinges 9 (see Fig. 4, position I). The front flaps 11 of the first and third buckets 10 open. During the movement of the tractor 1, the process of digging with the scraper train is carried out. In this case, the cutting edge 14 of the front bucket 10 of the scraper, whose width is equal to-half the width of the bucket 10, performs a blocked cutting, and the soil cut by it enters the front part of the bucket. The first pair of buckets 10 digs at the same level, while the rear cutting edge 15 of the second scraper bucket 10 carries out semi-blocks and cutting, filling the rear part of the second bucket. The second pair of buckets is filled in the same way, only the digging process is carried out at the second, lowest level. After the buckets 10 are half full, the front flaps 1I of the first and third buckets are closed, the hydrocyliidry 20 and 21 are reversed and the buckets 10 are returned to their original position. The rear loading slots in the second and fourth gauges are covered by non-voluntary movement of the rear movable walls by 12 hydraulic cylinders 13. Next, the front flaps 11 are opened in the second and fourth KOBUjax. When the hydraulic cylinders 20 and 21 are pulled in, the buckets 10 are turned in the opposite direction before the cutting edges 14 and 15 are introduced into the ground. The process of filling the buckets 10 is carried out in the same order, but if in the first case the front part of the bucket was filled, the rear part is now filled and vice versa (see Fig. 4, position P). After filling the buckets 10, the front flaps 11 close, and the rear movable walls 12 close the loading slots and carry out the transportation process. The unloading of the buckets is carried out by moving the rear moving walls 12. The invention will increase the productivity of the earthmoving and transshipment work by 60% by increasing the total capacity of the scraper train and the volume of soil being transported. At the same time, the cost of the developed soil is reduced by half compared to the cost of working the soil with single scrapers with the capacity of the bucket of the capacity of one scoop train bucket. Claims of invention Scraper train containing a frame and a frame associated with it on a chassis, to which double-slot ladles and hydraulic cylinders of their rotation are attached, characterized in that, in order to increase the efficiency of excavation and its mixing, by increasing the capacity of the train, the frame equipped with brackets rigidly attached to it and vertically mounted, with buckets attached to the pores that are articulated by pivoting levers to one another, while the frame is U-shaped, to the top of which are attached brackets and hydraulic cylinders for bucket turning, pivotally connected to the peripheral parts of the front and rear buckets 11 (her, and the lower frames are connected to the chassis and buckets are installed between them.
