Description

The invention relates to a lifting machinery industry, namely to belt conveyors, with a steeply inclined and horizontal transporting bulk material prone to sticking with large pieces.

The aim of the invention is to increase the efficiency of the conveyor by eliminating the stitching of spillage.

FIG. 1 shows a general view of a steeply inclined belt conveyor, side view; in fig. 2 is a section along A-A in FIG. 1; FIG. 3 is a view along arrow B of FIG. one; in fig. 4 shows a section along BB in FIG. one.

A steeply inclined belt conveyor consists of a stand 1, a pull body 2 in the form of bundles of ropes, crossbars 3 attached to them, a driving and tension drum 4 and 5, and a loading body in the form of tapes 6 and 7, which are hinged at one side along the outer edge 8 to the individual ropes of the traction bodies 2. The paws-traverses 9 are attached by clamps 10 to the same ropes of the traction organs 2, Cross-beams 3

they have wheels 11 at their ends, which rest on the guides 12 of the cargo and idler parts of the conveyor belt. The tape 6 in the working position is superimposed by its edge 13 on the edge of the tape 7. On the working side of the belt web there are flexible partitions 14 attached in the middle part to the crossbars 3 by the clamps 15, and on the sides attached to the traction bodies 2 by clamps 16 (Fig. 3) . The drive drum 4 in its middle part is made with an annular groove 17 (Fig. 1 and 4). In front of the drive drum 4, between the working and idle branches of the conveyor, a bypass discharge drum 18 is reinforced. The ring groove 17 and drum 18 bends around the closed web 19 with cheeks 20 (Fig. 4),

The web 19 is provided with partitions 21 with columns 22, which have stop pins 23 from the back side of the mounting side (Fig. 1). The pillars 22 are attached to the web 19 by hinges 24. On the inner side of the web (FIG. 4), there are fastening chains 25 (the web elements can be

fastened together and without chains), Under the discharge drum 18 above the working branch of the conveyor is installed 26 (Fig. 1). For feeding the cargo to the lower branch of the conveyor there is a bunker-feeder 27. Under the conveyor branch at the loading point there is a damping device 28.

The conveyor works as follows. - .. - -

The turning of the drum 4 together with the traction bodies 2 sets in motion the entire closed conveyor belt. After bending from top to bottom of the tension drum 5, the wheels 11 of the crossbars 3 are mounted on the guides 12 of the loading part of the conveyor belt. The belts 6 and 7 are then placed under the action of centrifugal force and own weight on the cross-arms 9 to form a groove.

Bulk cargo on the moving cargo branch comes from the feeder bunker 27. During the loading process, crossmembers 3 play the role of grates, partially absorbing the blows of large pieces as they are dumped into the load-carrying chute. The shock-absorbing device 28 in the place of loading also protects the belts 6 and 7, the cross member 9 from the occurrence of residual deformations in them, perceiving the energy of the blows of large pieces. Upon further transportation, the large pieces abut the cross-beams 3, keeping the small fractions of the load from sliding. In the case of transporting only a small bulk cargo, it is kept from slipping along the belts 6 and 7 by flexible partitions 14. The spilling of small fractions of the cargo is prevented by overlapping the edge 13 of the belt on the belt 7,

When a working branch with a load enters the drive drum 4 due to centrifugal force and supported by partitions 14 and 21, the flow of goods rises around the axis of rotation and rolls onto the web 19. At the same time, rotation of the legs 22 of the partitions 21 around the hinges 24 in the opposite direction is prevented by fi rests on the elements of the web 19. The load of the cargo in the slots on the sides of the web 19 protects its cheeks 20. In order to prevent pieces of cargo from being disassembled between

by partitions 21 in the straight part of the web 19, the legs 22 are able to pivot around the hinges 24 forward along the traffic flow. When rounding the blade 19 around the discharge bypass drum

18 provides the best conditions for transshipping cargo to receiving material loader 26.

In the process of moving the conveyor belt from bottom to top around the drum 4, the belts 6 and 7 are straightened, transferred and laid onto the cross-pieces 3 due to their own weight and tension. At the same time, the flexible partitions 14 are folded under the strips 6 and 7. From excessive sagging in

The side of the cargo branch is held by the clamps 15 and the clamps 16

In the process of moving the idle branch, the web is self-cleaning by scattering the adhering cargo particles on the cargo branch of the conveyor.

The use of the proposed technical solution allows more than 5% increase in the operational performance of the conveyor by reducing

forced pipeline stops due to spillage with spillage.
