Изобретение относитс к рабочему оборудованию одноковшового экскаватра с noBOpoTHfcJM ковшом и может быть использовано при разработке липких грунтов.The invention relates to the working equipment of a single bucket excavator with a noBOpoTHfcJM bucket and can be used in the development of sticky soils.

Известен ковш, установленный на руко ти, включающий днище цилиндрической формы, боковые стенки и очистное устройство, всшолненное в виде размещенной внутри ковша и жес ко закрепленной на руко ти рамки с двухсторонними заостренньами кромками . При каждом рабочем цикле ковша экскаватора без дополнительного привода на очистное устройство происходит очистка ковша о неподвижнуюA bucket mounted on a handle is known, which includes a bottom of a cylindrical shape, side walls and a cleaning device, complete in the form of a frame placed inside and fixed on the handle of a frame with double-sided pointed edges. At each working cycle of the excavator bucket without additional drive to the cleaning device, the bucket is cleaned on a fixed

Наиболее близким- техническим решением к предлагаемому вл етс рабочее оборудование экскаватора, включающее руко ть и поворотный ковш, содержащий верхний каркасный по с, режущий козырек и шарнирно соединенное с ним листЛое днище ц2 The closest technical solution to the present invention is the working equipment of the excavator, which includes a handle and a swivel bucket, containing the upper frame in c, the cutting visor and the bottom of hinge 2 hinged to it.

Недостаток такого оборудовани заключаетс в недостаточной эффективности разгрузки ковша, поскольку днищу в процессе разгрузки обеспечиваетс незначительное выталкивающее перемещение.The disadvantage of such equipment lies in the insufficient efficiency of the unloading of the bucket, since the bottom in the process of unloading provides a slight pushing movement.

Цель изобретени - повышение эффективности разгрузки ковша.The purpose of the invention is to increase the efficiency of unloading the bucket.

Указанна цель достигаетс тем, что руко ть выполнена с продольными направл ющими, а листовое днище имеет установленные в направл ющих ползуны и посредством шарнирных т г соединено с каркасным по сом.This goal is achieved by the fact that the handle is made with longitudinal guides, and the sheet bottom has slides installed in the guides and is connected to the frame brace by means of hinges.

На фиг. 1 изображено рабочее оборудование экскаватора, вид сбоку; на фиг. 2 - то же, вид сзади; на фиг. 3 - сечение А-А на фиг. 1.FIG. 1 shows the working equipment of the excavator, side view; in fig. 2 - the same, rear view; in fig. 3 is a section A-A in FIG. one.

ковш, состо щий из двух параллельных боковых стенок 1, соединенных между собой посредством полос 2 и режущего козырька 3. К стенкам 1 прикреплены боковые ножи 4. Ковш посредствомa bucket consisting of two parallel side walls 1 interconnected by means of strips 2 and a cutting visor 3. Side knives 4 are attached to the walls 1. Bucket by

Claims

The hinge 5 is attached to the handle 6 .. A sheet bottom 8 is attached to the cutting visor 3 by means of the hinge 7, the other end of which is connected to the rods 10 by means of the axis 9. Axis 9 is installed between the arm 6 and the restriction band 12. The bucket eye 11 and the arm eye 13 are interconnected by a hydraulic cylinder 14. The process of unloading the bucket is as follows. When retracted, the hydraulic cylinder 14 forces the bucket to rotate around the hinge 5. The ribs 10 move the axis 9 along the arm b to the extreme upper position. During the turn, the bucket 8 moves along the arm 6 following the axis 9 and gradually straightens The position shown in FIG. 1 thin lines. The soil, under the action of the straightening bottom 8, will be forcibly unloaded from the bucket. During ram up movement of the hydraulic cylinder 14, the bucket returns to its original position. In this case, the axis 9 moves along the handle 6 from the upper position to the lower position and moves together with the bottom B, which in the extreme position bends and occupies the position of the bottom of the bucket. Bucket unloading is automatic. The bottom 8 is returned to its original position, occurs gradually under the impact. - ton g 10 and the soil filling the bucket, which in the process of digging presses on the bottom 8. When the bottom 8 is bent, not only is the full unloading and cleaning of the side walls 1, but also shaking out soil adhering to the bottom. During the reverse course of the bottom, the remains of the ground adhering to the walls 1 were worn out. Claims of the excavator's working equipment, including a handle and a swivel bucket, containing a top framed c, cutting visor and a pivotally connected lugs, which are made so that, in order to increase the efficiency of unloading the bucket, the handle is made with longitudinal guides, and the sheet bottom has slides installed in the guides and, by means of hinges, is connected to the frame under ccm.
