Loose materials stower-gripper

FIELD: materials handling facilities.

SUBSTANCE: invention relates to devices for taking loose materials from pile and stowing them in layers differing in content of useful component in each layer with simultaneous averaging in process of taking material from pile and it can be used in open stores. Proposed loose material stower-gripper has boom of gripper and boom of stower of lift-lower type turnable in horizontal plane by slewing circle installed on base and drives to turn booms of gripper and stower. Slewing circle is made in form of fixed rings rigidly secured to each other and to frame of base, two coaxially arranged movable rings with gear rims resting of fixed rings through solids of revolution. Movable rings are non-connected mechanically, one movable ring being furnished with external teeth rim coupled with gripper boom turning drive, and the other is provided with internal teeth rim coupled with stower boom turning drive. Each toothed rim has independent self-contained system to regulate geometrical parameters of mating of solids of revolution with movable and fixed rings. Base be made in form of self-propelled chassis or stationary portal. Gripper boom has gripping member of rotary or scraper type.

EFFECT: reduced overall dimensions of stower-gripper, facilitated maintenance.

The invention relates to a device for sampling bulk material from a pile and laying it layers with different content of useful component in each layer, while averaging in the process of sampling from stacks and can be used for open storage.

Known stacker-Zaborski for bulk materials according to German patent DE 3732671 A1 (publ. 13.04.89), which includes the arrow of zaborska and boom stacker, rotary frame supporting the boom stacker through a rotation device, which relies on the turntable supporting boom zaborska, and between the rotating bed and turntable set your device as a drive rotating frame. This stacker-Zaborski closest to the offer.

This stacker-Zaborski for bulk material has large dimensions, as the boom stacker and zaborska is provided with a separate support-rotating devices located at a certain distance from each other.

The invention solves the problem of reducing the size of the stacker-zaborska and simplify its maintenance.

To achieve this, the technical result in the stacker-zaborska for bulk materials containing boom zaborska and boom stacker made lifting and lowering and rotating the horizontal plane by means mounted on the base means of a turntable, and drives rotation of the shafts of zaborska and stacker, in addition, the rotation device includes a stationary ring fixed between itself and the frame base means, and two coaxially arranged and kinematically unrelated movable ring with toothed crowns resting on the stationary ring via the rolling elements, one movable ring is provided with a ring gear with external teeth connected to the drive rotation arrows of zaborska, and the other movable ring is provided with a ring gear with internal teeth connected to the drive rotation of the boom stacker. Rotation device has a spacer for adjusting the position of the fixed rings relative to the rolling elements. The base means may be provided in the form of a self-propelled chassis or stationary portal. The arrow of zaborska intake has a rotary body or scraper type.

Distinctive features of the proposed stacker-zaborska for bulk materials from the above known closest to him, is to provide a turntable fixed rings rigidly mounted between and on the frame base means, and two coaxially arranged and kinematically interconnected movable rings with toothed crowns, operamini the stationary ring via the rolling elements, one mobile ring provided with a ring gear with external teeth connected to the drive rotation arrows of zaborska, and the other movable ring is provided with a ring gear with internal teeth connected to the drive rotation of the boom stacker. Rotation device has a spacer for adjusting the position of the fixed rings relative to the rolling elements. The base means may be provided in the form of a self-propelled chassis or stationary portal. The arrow of zaborska intake has a rotary body or scraper type.

Analysis of scientific-technical and patent literature shows that in the technique known rotation device for lifting machines. In particular, Standard series RD 900 (standard Germany, p.160-164) certifies that the rotation device includes a stationary ring and one movable ring with a ring gear supported on the stationary ring via the rolling elements in the form of rollers. This is a sliding ring can have an inner gear and outer.

Due to the presence of two rings with a toothed crowns offer the rotation device can be installed in zaboric-stacker for granular materials, with two arrows, one for intake, one for its installation.

Below is an example embodiment of the invention, n is excluding other options within the formula, with reference to figures 1 to 4, which shows:

figure 1 - General view of the stacker-zaborska for bulk materials;

figure 2 - installation of a turntable on the base means;

figure 3 is an enlarged view of a turntable in the incision;

figure 4 - drives rotation of the shafts stacker and zaborska.

Stacker-Zaborski for bulk materials, including boom zaborska 1, boom stacker 2 and drives the rotation shafts of zaborska 3 and stacker 4. Arrows of zaborska 1 and stacker 2 is made lifting and lowering by means of the braces 5 and 6, and rotatable in a horizontal plane by means mounted on self-propelled chassis 7 turntable 8. Rotation device made in the form of stationary rings 9-11, fixed between each other by bolts and nuts 12 and the frame 13 self-propelled chassis, and two rings 14,15 serrated crowns. Movable ring 14 fitted with a toothed crown 16 with outer teeth connected to the drive rotation arrows of zaborska 3, and the movable ring 15 provided with a ring gear 17 with the internal teeth connected to the drive rotation of the boom stacker 4. Movable ring located coaxially and supported on the stationary ring through the rollers 18-20, kinematically connected to each other. Rotation device is fitted with a gasket 21 for p is the regulation of the gap between the fixed rings 9, 10 and rollers 18, 19 and gasket 22 to regulate the gap between the fixed rings 10 and 11 and the rollers 18, 20. The arrow of zaborska 1 and boom stacker 2 is provided with flanges (not shown)resting on the annular support 23, 24 (figure 2), and fastened thereto by bolts. Annular bearings 23, 24 are fixed on the movable rings 14, 15 by bolts 25. The arrow of zaborska 1 has an intake body in the form of the rotor 26.

The work of the stacker-zaborska for bulk materials is carried out as follows. Self-propelled chassis 7 Zaborski-stacker is installed around the pile of loose material. When enabled, the drive rotation arrows of zaborska 3 gear 27 rotates the ring gear 16, which rotates the arm zaborska 1, rigidly mounted on a movable ring 14, and stops it in the place where you want to make a fence of bulk material bucket wheel 26. For packing granular material in a stack in a specific location enables the drive rotation of boom stacker 4. Gear 28 of the actuator 4 rotates the ring gear 17 and with it the boom stacker 2, rigidly mounted on a movable ring 15. The rotation of the movable ring 15 is independent of the rotation of the movable ring 14, as they are not tied in a single kinematic chain.

The use of the present invention allows to significantly simplify the design of the stacker-zaborska for seputeh the material and, at least to halve the weight of a turntable.

SUBSTANCE: method relates to blending of loose material in pile. When two flows of loose material are used, filling of pile is carried out in layers along ring divided into three sectors. In first sector filling is done by shuttle arc movement to form lower part of pile by first flow. In second sector upper part of pile is filled by shuttle arc movements onto lower part of pile made by first flow by second flow with provision of longitudinal shifting between upper and lower parts of pile and forming ready pile in second sector. In third sector, end unloading along ring towards second sector is carried out simultaneously.

EFFECT: increased quality of blending at use of one-layer pile.
