SU755961A1 - Bucket for loading lump material - Google Patents

Description

The invention relates to the working bodies of bucket loaders used for scooping, sorting and loading bulk materials into vehicles.

Known loader loading machine, equipped with a vibrator associated with a solid bottom of the bucket to reduce the introduction of the bucket into the immersed material [1]. However, the solid bottom of the bucket does not allow removal of small bulk material from the bucket that fell into it when scooping.

Closest to the invention to the technical essence and the achieved result is a bucket for loading bulk material, including rear and side walls and a bottom with teeth, made in the form of a lattice [2].

The disadvantages of this bucket are great resistance to the introduction of the bucket teeth into the material, as well as the jamming of pieces between the grid elements when loading and sorting the material, which reduces the efficiency of the bucket.

The purpose of the invention is to increase efficiency by reducing efforts

inserting the bucket teeth into the submersible material and preventing jams of material between the grid elements.

This goal is achieved by the fact that the lattice is made of fixed sections,

₅ rigidly attached to the rear wall of the bucket, and movable sections, each of which is pivotally mounted on the bucket with the possibility of its rotation in the longitudinal-vertical plane relative to the fixed sections by means of a vibrating mechanism. The vibration mechanism is made in the form of a double-acting hydraulic cylinder, the body of which is rigidly fixed on the rear wall of the bucket, and the stem is pivotally connected to the rear end of the corresponding movable section. The rear wall of the bucket is made with slots through which the rear ends of the movable sections pass.

FIG. 1 shows the proposed bucket, side view; in fig. 2 - the same, top view.

The bucket contains a slatted bottom 1,

20 consisting of three fixed sections 2

and two movable sections 3, which have a hinge connection between themselves 4. To the extreme fixed sections of the bottom two side walls 5 are rigidly attached, which between

they are rigidly connected by crossbars 6, to which the rear 7 and the upper 8 walls of the bucket are welded. On the rear wall of the bucket are fixed two vibration mechanisms, made in the form of double-acting hydraulic cylinders 9, which are connected via hinges 10 and rods 11 to the rear ends of 12 movable sections passing through slots 13 of the rear wall of the bucket.

The bucket works as follows.

When a bucket is inserted into a stack of bulk material, hydraulic cylinders 9 are double-acting, which, through hinges 10 and rods 11, act on the rear ends 12 of moving sections 3, telling them to oscillate relative to hinges 4. At the same time, the front edges of moving sections vibrate, reducing the bucket penetration forces in the stack of materials.

When fully buried in the stack of material, the bucket turns to the side of the loading equipment and rises to the height required for unloading. During the movement of the bucket from the stack to the vehicle, shaking the scooped soil into the bucket through the gaps of the bottom and rear wall of the bucket. In case of sticking of pieces of material in the slots 13 of the rear wall 7, the ends 12 of the movable sections 3, which are in oscillatory motion, knock them outward or inward of the bucket and, therefore, the jamming of the vibration mechanism is excluded.

When unloading stones into a vehicle, bucket vibrations may be stopped. In case of material getting stuck in the bucket when unloading the stones in order to speed up its emptying, you should also turn on the vibration mechanism.

The invention makes it possible to ensure a reduction in the implementation effort to 4 ° / _o and the clogging of lump materials in soils from 30% to 5% and an increase in the fill factor by 8-10%.
