Description

The invention relates to loading machines and can be used in working agencies of earth-moving machines.

Designs of loading machines are known in which, in order to reduce the resistance to the introduction of the working body into the lumpy bulk cargo, the front cutting edge performs transverse oscillations in the vertical plane 1.

Closest to the present invention is a loader bucket, comprising a bottom and a movable cutting part, connected by rods with vibration exciters 2.

A disadvantage of the known constructions is the inability to control the direction of oscillation of the active edge of the bottom of the bucket. When scooping packed cargo, coke and baths are the most effective, coinciding with the direction of bucket insertion. When scooping bulk and bulk cargo, the effect is only oscillations in the vertical plane in a direction close to perpendicular to the bottom of the bucket. Thus, buckets can be used on loads of only a certain type.

The purpose of the invention is to expand the technological capabilities of the bucket.

This goal is achieved by the fact that 1; 1 tangles are rigidly connected to the movable cutting part and pivotally to vibration excitators, the housings of which are hingedly connected to the bottom, and the bucket is equipped with directional bushings through which the rods are passed, As the sleeve is mounted on the bottom by means of a transverse axis, which has an adjustable detachable pin for tight connection with the days

15 soup or barbell.

20 of FIG. one; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 - loader bucket for development with cargo.

The loader bucket includes a movable cutting part 1, made separately from the bottom 2 of the bucket, two rods 3 rigidly connected to the cutting part, mounted in guide sleeves 4. The guide sleeves are fixed on axles 5, and the last

30 through sleeves 6 - on brackets 7 mounted on the bottom of the bucket. The brackets have eyelets 8 with holes. Drillings were performed in axis x 5: mutually perpendicular — in the middle section and one at a time — at the ends of the axes. One of the middle drillings is intended for the passage of the rod, the other two - for the installation of a removable adjustable finger 9. Radial drillings are also performed in the rods. The rods 3 are equipped with devices that regulate their length, including coupling 10 with left and right threads and screws 11 and 12 , and pivotally connected to the rods of synchronously operating exciters 13. Two brackets 14 and 15 are provided for fastening the exciters on the bucket. From the bottom, the rods with exciters are covered by a casing 16. The device operates as follows. When loading dense packed loads, when longitudinal oscillations are most effective, vibration exciters 13 are fixed on brackets 14 °, fingers 9 are installed in aligned holes of axes 5 and eyelets 8 thus fixing guide sleeves 4. When vibration exciters are turned on, their rods through rods 3 communicate cutting parts reciprocating movement in the direction of bucket insertion. When loading loose, easily flowing loads, when the cutting edge oscillates in the plane most effective, the exciter 13 is fixed on the brackets 15 perpendicular to the bottom of the bucket on the brackets 15, and using the clutches 10, the axial axial rods of the exciters, 13 and the axes of the rods 3, and the finger 9 sets in the combined drilling

fj rods 3 and axles 5, secured the rods motionless relative to the axes. In the reciprocating movement of the rods of the vibration exciters, the rods perform oscillating movements around the axes 5. The cutting part of the bucket is then driven into an oscillatory movement in a plane perpendicular to the bottom of the bucket. The application of the proposed loader bucket, Edge, the possibility of vibration in different planes, allows the technological capabilities of the bucket to be expanded when it is used on soils of various densities. Claims of the loader bucket, including the bottom and the movable cutting part, connected by rods with vibration exciters, are characterized in that, in order to expand its technological capabilities, the rods are rigidly connected to the movable cutting part and hingedly to vibration exciters, the bodies of which are pivotally connected with the bottom, and the bucket is provided with guide sleeves mounted on the bottom, through which the rods are passed, each guide sleeve is mounted on the bottom by means of a transverse axis, which has an adjustable finger for hard connection to the bottom or bar.
