Problems solved by technology

[0003] Coal mines and coal preparation plants need to use various belt conveyors. When using the existing large-inclination belt conveyor, the folds on the folded ring edge of the skirt belt and between the folded ring edge, the vertical partition and the endless base belt Some pulverized coal or coal particles are often entrained in the included angle, and these entrained pulverized coal or coal particles are still partially retained when passing through the discharge port with the skirt belt, and the remaining coal powder or coal particles are turned downward with the skirt belt. state, and gradually fall off to the ground below the frame of the belt conveyor with a large inclination angle. On the one hand, it will cause a waste of coal resources, and on the other hand, it will also pollute the ground and air on the site.

Embodiment approach 1

[0019] Implementation mode one: if Figure 1-2 As shown, the large-inclination belt conveyor includes a frame, a driving roller 1, a driven roller 2 and a skirt belt 3, and the frame includes a horizontal feed section 4, an intermediate inclined section 5 and a discharge section 6, and the discharge section The section 6 is higher than the horizontal feeding section 4, and the two ends of the middle inclined section 5 are respectively connected to the horizontal feeding section 4 and the discharging section 6, and the driving roller 1 shaft is mounted on the head end of the horizontal feeding section 4, and the driven roller 2 shafts are installed at the tail end of the discharge section 6, and the skirt belt 3 includes an annular base belt 31, and the outer surface of the annular base belt 31 is provided with two parallel pleated ring edges 32, and between the two parallel pleated ring edges 32 The annular base belt 31 is also provided with a plurality of vertical partitions ...

Embodiment approach 2

[0024] Implementation mode two: if image 3 , 4 As shown: the main shaft 71 between the two small pressure wheels of the upper corner pressure wheel 7 is provided with a plurality of protruding coal racks 11, and each coal rack 11 is composed of two fan-shaped racks 101 and two fan-shaped racks. Two connecting rods 102 between the racks 101 are formed. The above-mentioned coal racks 11 are evenly arranged around the main shaft 71. When the lower skirt belt 3 passes by, the above-mentioned coal racks 11 are pushed into each of the lower skirt belts 3 one by one. In the feeding grid 12 formed by the adjacent vertical partitions 33 and the endless base belt 31 .

[0025] A coal collecting hopper 13 is arranged below the upper corner pressure wheel 7, and the coal collecting hopper 13 communicates with the matching downstream coal hopper 14 of this large-inclination belt conveyor.

Abstract

The invention relates to a large-inclination-angle belt conveyor. By using an existing large-inclination-angle belt conveyor, waste of coal resources and pollution to the field are likely to happen. The large-inclination-angle belt conveyor comprises a rack, a driving roller, a driven roller and a skirt belt. The rack comprises a horizontal feeding section, a middle inclined section and a discharging section. The driving roller is arranged at the head end of the horizontal feeding section through a shaft. The driven roller is arranged at the tail end of the discharging section through a shaft.The axial line height of the driving roller is lower than the axial line height of an upper corner pressing wheel. The tail end of the discharging section is inclined downwards. The discharging section is inclined downwards. When the skirt belt passes through the driving roller, corrugated ring edges are downward and fully expanded, so that coal powder or coal particles are more favorable for falling off. Most of the entrained coal powder or coal particles can fall into a matched downstream coal chute in time. The large-inclination-angle belt conveyor has the beneficial effects of being simple in structure, low in coal resource waste and small in on-site pollution and is widely applicable to coal enterprises such as large coal mines and coal plants.

Description

technical field [0001] The invention relates to a belt conveyor with a large inclination angle. Background technique [0002] For ordinary belt conveyors, the maximum inclination angle should not exceed 19 degrees. The large-inclination belt conveyors all use skirt belts. The main body of the skirt belt is an annular base belt. plate. The belt conveyor with this structure can realize large inclination angle conveying. As in the 015.01.07 authorized announcement, the Chinese utility model whose authorized announcement number is CN204078741U discloses a kind of belt conveyor with large inclination angle. [0003] Coal mines and coal preparation plants need to use various belt conveyors. When using the existing large-inclination belt conveyor, the folds on the folded ring edge of the skirt belt and between the folded ring edge, the vertical partition and the endless base belt Some pulverized coal or coal particles are often entrained in the included angle, and these entrain...
