(54) КОВШ ЗЕМЛЕРОЙНОЙ МАШИНЫ(54) DIGGER BUCKET

1one

Изобретение относитс к землеройному машиностроению и может быть использовано в многоковшовых цепных экскаваторах с принудительной разгрузкой грунта из- ковшей, в частности в многоковшовых каналоочистител х .The invention relates to earthmoving machinery and can be used in multi-bucket chain excavators with forced soil unloading with ivy, in particular in multi-bucket channel cleaners.

Известны ковши с принудительной разгрузкой , состо ш,ие из боковых стенок с дниш ,ем и задней стенки. При движении ковша, задн стенка взаимодействует с толкателем , закрепленным на ковшовой раме, и поворачивает заднюю стенку. При этом грунт выталкиваетс из ковша. Возврат задней стенки в исходное положение осуш,ествл етс под действием собственного веса 1.Known buckets with forced discharge, consisting of side walls with the bottom and rear wall. When the bucket moves, the rear wall interacts with the pusher mounted on the bucket frame and rotates the rear wall. The soil is then pushed out of the bucket. The return of the rear wall to its original position is dried under its own weight 1.

Наиболее близким к предлагаемому вл етс ковш землеройной машины, содержаш ,ий дниш,е, боковые стенки и выталкиватель в виде криволинейной поворотной стенки, шарнирно установленной в ковше и имеюш .ей нижнюю и боковые грани 2.Closest to the present invention is a bucket of a digging machine, containing, its bottom, e, side walls and an ejector in the form of a curvilinear pivot wall hinged in the bucket and having lower and side faces 2.

Недостатком этого ковша вл етс неудовлетворительна эффективность его очистки при работе на грунтах, имеюших волокнистые включени в виде водорослей или травы.The disadvantage of this bucket is the unsatisfactory efficiency of its cleaning when working on soils that have fibrous inclusions in the form of algae or grass.

Цель изобретени - повышение эффективности выгрузки грунта, имеющего волокнистые включени .The purpose of the invention is to increase the efficiency of unloading soil having fibrous inclusions.

Эта цель достигаетс тем, что в ковше землеройной машины, содержащем дниш,е,This goal is achieved by the fact that in the digger bucket containing the bottom, e,

5 боковые стенки и выталкиватель в виде криволинейной поворотной стенки, шарнирно установленной в ковше и имеющей нижнюю и боковые грани, кажда грань поворотной стенки выполнена волнообразной по длине и скошенной в сторону днища ковша, причем волнообразные грани образуют с внутренней поверхностью ковша острый угол.5 side walls and an ejector in the form of a curved rotary wall hinged in a bucket and having lower and side faces, each edge of the swing wall is wavy in length and sloping towards the bottom of the bucket, and the wave-like edges form an acute angle with the inner surface of the bucket.

На фиг. 1 изображен ковш, разрез; на фиг. 2 - вид А на фиг. 1.FIG. 1 shows a bucket, a cut; in fig. 2 is a view A of FIG. one.

Ковш состоит из двух боковых стенок 1,The bucket consists of two side walls 1,

Claims

15 the bottom 2 and the pivot rear wall 3, made in the form of a curvilinear surface with lower and side faces 4. Wall 3 has a protrusion 5 and a power spring 6, which are integrally formed. The wall rotates around an axis 7 supported on the side walls of the bucket 1. The bucket is attached to two traction chains 8 with the help of the hinge lever 9 and the hinge 10. The unloading process is carried out using a roller pusher 11 fixed on the bucket frame 12. The bucket works as follows in a way. When the bucket moves, the protrusion 5 interacts with the roller pusher 11 and drives the rear wall 3, while its face 4, forming an acute angle with the inner surface of the bucket, cuts the soil from the bottom 2 and side walls 1. The cropped soil moves upward along the curvilinear rear wall 3, prevents sticking. At the same time, plant residues trapped between the front surface, the face 4 of the wall 3 and the inner surface of the bucket, due to the wave shape of the face 4, are displaced into the depressions of the face and, forming a wedge, are cut by the edge of the face 4. As a result, the plant mass is pushed out of the bucket and cleaning the bucket surface occurs more efficiently. The use of a bucket in multi-bucket channel-cleaning excavators allows to reduce the power consumption of unloading, to prevent sticking of the rear wall and to increase the capacity of buckets with the same metal intensity. Claims of the excavation bucket comprising a bottom, side walls and an ejector in the form of a curvilinear turning wall, hinged in the bucket and having bottom and side faces, characterized in that, in order to increase the efficiency of unloading the soil having fibrous inclusions, each face of the turning wall made wavy in length and beveled towards the bottom of the bucket, and the wave-like faces form an acute angle with the inner surface of the bucket.
