Description

The invention relates to equipment for the mining industry, namely to bending scraper conveyors.

The purpose of the invention is to increase the operational reliability of the stav by taking into account the formation hypsometry.

Figure 1 shows the junction of two sections of the stavka scraper bending conveyor, top view; figure 2 is a section aa in figure 1.

Becoming a scraper bending conveyor includes interconnected locks of section 1 with bottoms 2 and sidewalls 3. Between the sidewalls of 3 sections 1 there are inserted lattices 4 with bottoms 5 and sidewalls 6. Each lock for connecting sections 1 is made in the form of two located between the bottoms 2 and 5 sections and insert pans of semicircular plates

7, the diameters of which are equal to the width of the bottoms of 2 sections. On the lower sides of the semicircular plate 7 is made with arc ledges

8, arranged concentrically to the arc surfaces of the plates 7, and on the straight sides, the semicircular plates 7 are made with loops 9 engaged with each other and connected by means of a horizontal finger 10 with the possibility of mutual rotation of the sections 1 in a vertical plane. The bottoms of the 2 sections are made with arc grooves 11, the length of which is greater than the length of the arc protrusions 8 located in the arc grooves 11 with the possibility of mutual rotation of the sections 1 in the horizontal plane.

Becoming a scraper bending conveyor works as follows.

When the conveyor sections are turned in a vertical plane, the semicircular plates 7 receive angular displacements around the finger 10. When the conveyor sections are turned in a horizontal plane, the semicircular plates 7 together with the finger 10 and the arc protrusions 8 are rotated around the vertical axis. The transverse movement of one section of the conveyor relative to another neighboring section of the design is excluded. Linear movements of the section relative to each other are possible within the guaranteed gaps. This constructive implementation of the connecting nodes of the stavka eliminates the occurrence of bending moments when moving the conveyor along the formation hypsometry, provides mutual linear displacement of the sections within the guaranteed gaps along the conveyor, eliminates lateral shifts of adjacent sections at the joints, which ensures normal passage of the combine at the joints of the sections and allows the conveyor to bend in mutually perpendicular planes, spillage of the transported material from the transport the groove to the idle branch, and the presence of bevels at the ends of the bottom of the detachable pan, converging to the center of rotation of the section (Fig. 1), provides a smooth, without jolting, stroke of the traction body of the conveyor.
