Abstract

The invention relates to conveyor transport and allows to simplify the design and increase reliability. The loading device contains inclined grate bars / K / 1, mounted on the base between the conveyors 12,13 through fastening elements in the form of a guide / H / 7 with a hole. Under the middle part K 1 there are supports in the form of arcuate base 3 mounted on the axles with the possibility of rotation and fixation. The tilting moment from the lower shoulder K 1 is less than the tilting moment of the upper shoulder. The upper arms K 1 are mounted in the openings H 7 transversely and made at the end with the tide to hold them in H 7. The pieces of material are fed from the conveyor 12 to the part K 1 that rotates around the base 3. Those grate bars that hold piece of cargo. This provides an independent oscillation K 1 relative to each other in the supports along the arc of a circle whose radius is the distance between the support and H 7. The angle of inclination K 1 increases, which contributes to a better rolling of the pieces and dropping them from a lower height onto the conveyor body 13. Due to the increasing lengths of the shoulders K 1, the direction of the rolling of the pieces is oriented towards the center of the load-carrying body, ensuring the necessary formation of the cargo flow. 1 hp f-ly, 3 ill.

Description

This invention relates to a loading device for conveyors for loose soils.

The aim of the invention is to simplify the design and increase reliability.

Figure 1 shows the device, side view; FIG. 2 is a section A-A in FIG. one; on fig.Z - section bb in figure 2.

The device contains inclined rotary curved grate 1 (FIG. 1) mounted with the middle part on the supports 2 in the form of an arcuate base 3 and forming two shoulders levers (FIG. 2). The grid bars are mounted relative to each other with a gap of 4 increasing to the lower ends of the grid bars. The ends of the arcuate base 3 are installed in the axis x 5 with the possibility of rotation and rigid fixation in a predetermined position. This provides a different arrangement of the supports 2 relative to the ends of the grate bars and, therefore, is not (the trays are loaded into the loading device. The upper ends of the grate 1 are installed in the openings 6 of the guide 7 with the gap 8 between the upper-) edge of the grate 1 and the upper edge 9 the holes 6 and have tides 10 for holding the grate 1 in the Hole 6. The hole guides with hundreds of holes are the fixing elements of the ttpai grate. The upper arm of each grate 1 is made with a mass exceeding the mass of its lower furnace, i.e. the overturning moment of the upper furnace is greater than the overturning moment of the lower grate shoulder. Therefore, the second support point of the grate is the bottom edge 11 of the hole 6 in the guide 7. The conveyor 12 delivers the load To the loading device, and the load 13 receives the load.

The device works as follows.

Small pieces of bulk cargo transported by conveyor 12 (soil fall onto conveyor 13 through the upper part of the grate 1. The middle pieces, however, not passing through the inter-grate space, roll down the grates

1and, falling on their lower ends, change the mass of the lower arms of the grate. Grate bars turn around pylons

2 to the size of the gap 8. At the same time, the grate bars that hold the piece of cargo turn. This

An independent oscillation of the grate 1 relative to each other in the supports 2 along the arc of a circle, the radius of which is the distance between the support 2 and the guide 7, by the size of the gap 8. lower height on the loading body of the receiving conveyor 13. When transporting larger pieces of soil, the latter, having a large kinetic energy, hit the lower ends of the grate. The grate rotates sharply around the supports 2 and the upper ends hit the face 9 in the holes 6 of the guide 7. The kinetic energy of the piece of soil is extinguished and it rolls onto the load-carrying organ of the conveyor 13 from a small height. Due to such sharp shocks, the soil sticking to the grate bounces off and the grate self-cleans.

When large and medium pieces of transported soil fall on the grate due to the increasing lengths of the arms and, consequently, their masses at the grates located closer to the longitudinal axis of the device, and due to the lotiness in the grate installation, the direction of rolling of the soil pieces is oriented to provide the necessary the formation of cargo traffic. Pieces of soil fall on the carrying body from a smaller height, reducing wear on the latter. The filling of the space under the grid-irons is practically excluded, since the supports of the grid-bars are located high above the load-carrying bodies. By turning the arcuate base 3 in the axis x 5, it is possible to displace the supports 2 with the grid bars 1 and, consequently, change the tray and mass of the bars of the grid bars.
