(5) КОВШ ЭКСКАВАТОРА-ДРАГЛАЙНА(5) BUCKET EXCAVATOR-DRAGLINE

Изобретение относитс к землеройным , строительным и горным машинам , а именно к сменному рабочему оборудованию экскаваторов-драглайнов предназначенных дл производства вскрьниных и других видов земл ных ра бот. Известен ковш экскаватора-драглай на, который включает днище, боковые и заднюю стенки и упр жь 11. у Недостатком этой конструкции вл етс налипание грунта в ковше, очистка которого возможна только вручную. Наиболее близким к предлагаемому по технической сущности и достигаемо му результату вл етс ковш экскаватора-драглайна , который включает днище, боковые и заднюю стенки, упр жь и узел самоочистки ковша в ви де состо щего из секций, соединенных между собой посредством звеньев цепей , расположенного во внутренней полости ковша и шарнирно закрепленного в верхней части задней стенки f2j. Недостатком конструкции такого ковша вл етс неудовлетворительна самоочистка ковша из-за пассивности очистки, происход щей под действием собственного веса щита и налипшего на него грунта. Цель изобретени - повышение качества очистки ковша. Указанна цель достигаетс тем, что задн часть днища и нижн часть задней стенки выполнены с вырезом и имеют жестко закрепленные на боковых стенках поперечные оси, а узел самоочистки ковШа выполнен из установленных на ос х с возможностью вращени валиков.. На фиг. 1 изображен ковш экскаватора-драглайна , вид сбоку; на фиг. 2 то же, вид сверху. Ковш экскаватора-драглайна включает днище 1, боковые 2 и заднюю 3 стенки и упр жь 4. В задней части днища 1The invention relates to earthmoving, construction and mining machines, namely, to replaceable working equipment of dragline excavators intended for the production of open-pit and other types of earthworks. The bucket of a dragline excavator is known, which includes the bottom, side and rear walls, and the tension 11. The disadvantage of this design is that the soil sticks to the bucket, which can only be cleaned manually. The closest to the proposed technical essence and the achieved result is the dragline excavator bucket, which includes the bottom, side and rear walls, cushioning and a self-cleaning unit of the bucket in the form of sections interconnected by means of chain links located in the internal cavity of the bucket and hinged at the top of the rear wall f2j. A disadvantage of the design of such a bucket is the poor self-cleaning of the bucket due to the passivity of the cleaning, which occurs under the action of its own weight of the shield and the soil adhering to it. The purpose of the invention is to improve the quality of cleaning the bucket. This goal is achieved by the fact that the rear part of the bottom and the lower part of the rear wall are made with a cut-out and have transverse axes rigidly fixed on the side walls, and the self-cleaning unit of the bucket is made of axles mounted on the axes with the possibility of rotation. 1 shows a dragline excavator bucket, side view; in fig. 2 the same, top view. The dragline excavator bucket includes bottom 1, side 2 and rear 3 walls, and tension 4. At the rear of the bottom 1

Claims

The claims are not cut-out in which the rollers 5 are mounted rotatably on the axles 6, rigidly fixed to the side walls 2 of the bucket. The bucket works as follows. When the bucket moves along the bottom during digging, the rollers 5 of the bottom 1 are driven into rotation as a result of friction against the soil, due to which the soil at the beginning of digging does not remain at the rear of the bottom 1, but moves along the bucket. With the further entry of soil into the bucket under its action, the rollers 5 of the rear wall 3 come into rotation. The rotation of the rollers 5 during digging ensures a constant movement of soil in the bucket at the rear wall 3, and, consequently, its cleaning. 20 Dredger excavator bucket, including a bottom with a cutting edge, side and rear walls and a bucket self-cleaning unit, with the aim of improving the quality of cleaning the bucket, the back of the bottom and bottom the rear wall is made with a cutout and has transverse axes rigidly fixed to the side walls, and the bucket self-cleaning unit is made and mounted on the axles with the possibility of rotation of the rollers. 5 Sources of information taken into account in the examination
