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

Известен ковш скрепера, с двухножевой системой загрузки 1.The scraper bucket is known, with a two-knife loading system 1.

Однако этот скрепер обладает недостаточной производительностью, так как наполнение ведетс лишь за счет т говой силы.However, this scraper has insufficient productivity, since the filling is carried out only by pulling force.

Наиболее близким техническим решением к изобретению вл етс скрепер, включающий базовую машину и ковш, содержащий боковые стенки и установленный на них загрузочный механизм с режущим ножом 2.The closest technical solution to the invention is a scraper comprising a base machine and a bucket containing side walls and a loading mechanism mounted thereto with a cutting knife 2.

Недостатком известного скрепера вл етс невозможность многократного перемещени грунта внутрь ковша и невозмож .ность загрузки с помощью загрузочного механизма удлиненных ковшей, что снижает его производительность.A disadvantage of the known scraper is the impossibility of repeatedly moving the soil inside the bucket and the impossibility of loading with the help of the loading mechanism elongated buckets, which reduces its productivity.

Целью изобретени вл етс повышение производительности за счет увеличени сместимости ковша и уменьшени энергоемкости его заполнени .The aim of the invention is to increase productivity by increasing the bucket's displaceability and reducing the energy intensity of its filling.

Указанна цель достигаетс тем, что в скрепере, включающем базовую машину иThis goal is achieved by the fact that in the scraper, which includes the base machine and

основной ковш, содержащий боковые стенки и установленный на них загрузочный механизм с режущим ножом и приводом, загрузочный механизм выполнен в виде поворотного дополнительного ковша .с выдвижной плитой, расположенной под его днищем.the main bucket containing side walls and a loading mechanism mounted on them with a cutting knife and a drive, the loading mechanism is designed as a rotating additional bucket. With a sliding plate located under its bottom.

Привод поворотного ковша имеет гидродвигатели с шестерн ми, установленными с каждой стороны дополнительного ковша, а верхние кромки боковых стенок ковша выполнены в виде дуги окружности с центром, совпадающим с осью поворота дополнительного ковща, и снабжены зубчатыми рейками , взаимодействующими с -щестерн ми.The rotary bucket drive has hydraulic motors with gears installed on each side of the additional bucket, and the upper edges of the side walls of the bucket are made in the form of an arc of a circle with the center coinciding with the axis of rotation of the additional bucket and are equipped with gear racks that interact with the gears.

На фиг. 1 изображен скрепер с загрузочным механизмом; на фиг. 2 и 3 - схемы 15 работы загрузочного механизма.FIG. 1 shows a scraper with a loading mechanism; in fig. 2 and 3 are diagrams 15 of the operation of the loading mechanism.

Claims

The scraper includes a base machine 1, a tangent frame 2 with a main bucket 3 mounted on it with a retractable rear wall 4 and a hydraulic cylinder 5 for its drive. The bucket is deepened by a hydraulic cylinder 6. On the side walls of the 7 bucket, a loading device 8 is installed, made in the form of a rotating additional bucket 9 with a sliding plate 10 located in rails located under the bottom of the additional bucket 9. The plate is moved by the hydraulic cylinder 10 through two shoulders 11 mounted on the hinges 12. Each lever is made with a groove 13. In the upper part of the additional bucket, on each side are installed hydraulic motors 14 with gears 15, which engage with the Knotted rails 16, made on the upper edges of the side walls of the main bucket. An additional bucket is mounted on the side walls of the bucket by means of levers 17. Buckets are equipped with cutting knives 18 and 19. The scraper works as follows. At the beginning of digging, the additional bucket is in the Lower position, the sliding plate is located in the main bucket. After filling the additional bucket and increasing the pulling force, the additional bucket is turned over the main bucket. In this case, the retractable damper mixes the soil inside the main bucket, and the soil in the additional bucket pours into the back of the main bucket. The movement of the scraper at this moment continues, and the ground, cut with a knife of the main bucket, sinks into its front part. After unloading the soil from the additional bucket, it returns to its original position, and its knife is buried in the ground. The ground at that moment between the knives of the bucket is cut by the knife of the main bucket, after which the sliding plate is pushed back into the main bucket, and the cycle is repeated. At the end of the digging, after the main and additional buckets are filled, the buckets are raised to the transport position and the ground is transferred to the place of discharge. The soil is unloaded by a retractable rear wall. The use of a loading mechanism in the form of an additional swivel bucket with a sliding plate improves productivity by reducing the energy intensity of the digging and increasing the capacity of the bucket. Claim 1. Scraper, comprising a base machine and a main bucket, containing side walls and a loading mechanism with a cutting knife and drive mounted on them, characterized in that, in order to increase productivity, the loading mechanism is made in the form of a rotary supplement with a sliding plate, located under its bottom. 2. A scraper according to claim 1, characterized in that the rotary bucket drive has hydraulic motors with gears mounted on each side of the additional bucket, and the upper edges of the side walls of the bucket are made in the form of an arc of a circle with a center. Coincident with the axis of rotation of the additional bucket, and equipped with gear racks, interacting with the gears. Sources of information taken into account in the examination 1.
