Description

.Изобретение относится к землеройным, строительным и горным машинам, а именно к сменному рабочему оборудованию экскаваторов-драглайнов, предназначенных для производства всКрышных и других видов земляных работ.. The invention relates to earthmoving, construction and mining machines, namely to replaceable working equipment of dragline excavators, designed for the production of Roof and other types of earthwork.

Известен ковш экскаватора-драглайна, содержащий днища с режущей кромкой и боковые и заднюю стенки [1].Known bucket excavator dragline containing bottoms with a cutting edge and side and rear walls [1].

Недостатком конструкции такого ковша является необходимость специальных операций по очистке ковша от налипания в нем грунта в процессе работы экскаватора.The disadvantage of the design of such a bucket is the need for special operations to clean the bucket from sticking soil in it during the operation of the excavator.

Наиболее близким.к предлагаемому по технической сущности и достигаемому результату является ковш экскаватора-драглайна, который содержит днище с режущей кромкой, боковые и заднюю стенки и узел самоочистки ковша. Последний содержит расположенный во внутренней полости ковша и шарнирно закрепленный в верхней части задней стенки секционный щит [2].The closest to the proposed technical essence and the achieved result is a dragline excavator bucket, which contains a bottom with a cutting edge, side and rear walls and a bucket self-cleaning unit. The latter contains located in the inner cavity of the bucket and pivotally mounted in the upper part of the rear wall of the sectional shield [2].

Недостатком известного ковша является его неудовлетворительная самоочистка, которая обусловлена лишь соб ственным· весом щита и налипаемого на нем грунта.A disadvantage of the known bucket is its unsatisfactory self-cleaning, which is due only to the proper weight of the shield and soil adhering to it.

Цель изобретения - повышение качества очистки внутренней поверхности ковша.The purpose of the invention is improving the quality of cleaning the inner surface of the bucket.

- Поставленная цель достигается тем, ^э что днище и нижняя часть задней стенки выполнена с продольными прорезями, а узел самоочистки выполнен из контактирующих с внутренней и внешней I» поверхностями днища поперечных балок с двухсторонними режущими кромками, при этом балки связаны между собой посредством расположенных в прорезях стягивающих колец.- The goal is achieved, ^e that the bottom and lower part of the rear wall is provided with longitudinal slots, and the self-cleaning assembly is made of the contact with the internal and external I »surfaces of the bottom cross beams with bilateral cutting edges, wherein the beams are interconnected by means arranged in the slots tightening rings.

На фиг. 1 изображен предлагаемый ковш, вид сбоку; на фиг. 2 — ковш, вид сверху; на фиг. 3 и 4 - ковш в процессе работы.In FIG. 1 shows a proposed bucket, side view; in FIG. 2 - bucket, top view; in FIG. 3 and 4 - the bucket during operation.

Ковш экскаватора-драглайна вклю20 чает днище 1 с режущей кромкой 2, боковые стенки 3 и заднюю стенку 4. В днище 1 и нижией части задней стенки 4 выполнены продольные прорези 5, в которых расположены кольца 6, стя^ гивающие балки 7 и 8, которые выполч йены с двухсторонними режущими кром->The excavator dragline bucket 20 includes a bottom 1 with a cutting edge 2, side walls 3 and a rear wall 4. In the bottom 1 and the lower part of the rear wall 4 there are longitudinal slots 5, in which there are rings 6, tightening beams 7 and 8, which Yen with double-sided cutting chrome->

Ковш работает следующим образом.The bucket works as follows.

При движении ковша по забою балки и 8 за счет воздействия на послед3 нюю грунта под днищем 1 перемещаются к расположенным на задней стенке 4 концам прорезей 5. При разгрузке бал-¹ки 7 и 8 под действием собственного веса перемещаются в исходное, положение и, срезая налипший грунт, производят очистку ковша от налипшего грунта При забрасывании ковша в забой он протаскивается по забою на задней стенке 4 или днище 1 в сторону от базовой машины, в результате чего балкам 7 и 8 обеспечивается надежное сме-γθ щение в исходное положение.When the bucket movement slaughter beam 8 and by affecting the posled3 nyuyu soil under the bottom 1 to move on the rear wall 4 of the ends of the slits 5. When unloading bal- ¹ ki 7 and 8 by their own weight are moved to the initial, position and cutting adhering soil, the bucket is cleaned of adhering soil When throwing the bucket into the face, it is dragged along the face on the rear wall 4 or bottom 1 to the side of the base machine, as a result of which beams 7 and 8 provide reliable displacement to the initial position.

Claims

The invention relates to earthmoving, construction and mining machines, in particular to a replaceable working equipment of dragline excavators intended for the production of all-purpose and other types of earthworks. The excavator dragline bucket is known, which contains the bottom with a cutting edge and the side and rear walls 1. The design of such a bucket is lacking in that it is necessary to perform special operations to clean the bucket from sticking in it during the operation of the excavator. The closest to the proposed technical essence and the achieved result is the bucket of a dragline excavator, which contains a bottom with a cutting edge, side and rear walls and a self-cleaning unit of the shaft. The latter contains a sectional shield 2 located in the internal cavity of the bucket and hinged in the upper part of the rear wall. A disadvantage of the known bucket is its poor self-cleaning, which is caused only by proper weight of the shield and the soil adhering to it. The purpose of the invention is to improve the quality of cleaning the inner surface of the bucket. The goal is achieved by the fact that the bottom and the lower part of the rear wall are made with longitudinal slits, and for: self-cleaning is made of cross-beams in contact with the inner and outer surfaces of the bottom with double-sided cutting edges, while the beams are interconnected by Slot x retaining rings. FIG. 1 depicts the proposed1 "LY bucket, VIA from the side; in fig. 2 - a ladle, top view; in fig. 3 and 4 - bucket in the process. The coitt of the dredge excavator includes a bottom 1 with a cutting edge 2, side walls 3 and a rear wall 4. In the bottom 1 and the lower part of the rear wall 4, longitudinal slots 5 are made, which have rings b, pulling heads 7 and 8, which are with double-sided chrome-bucket cutters, the bucket works as follows. When the bucket moves along the face, the heads 7 and 8, due to the impact on the soil after the bottom 1, move to the 4 ends of the slots 5 located on the rear wall. When unloading, the beams 7 and 8 under the action of their own weight move to their original position, and the bucket is cleaned from sticking soil. When throwing the bucket into the bottomhole, it is dragged along the face of the bottom wall 4 or bottom 1 away from the base machine, as a result of which the bars 7 and 8 provide a reliable movement to its original position. Claims of a dragline excavator bucket with a cutting edge, side and rear walls and a self-cleaning unit, characterized in that, in order to improve the quality of cleaning its inner surface, the bottom and bottom of the rear wall are made with longitudinal slits, and the node Self-cleaning is made of transverse beams in contact with the inner and outer surfaces of the bottom with double-sided cutting edges, while the beams are interconnected by means of tension rings located in the slots.
