Embodiment Construction
[0008] The specific implementation of the present application will be described below with reference to FIG. 1 .
[0009] As can be seen from Figure 1, it is generally composed of a roller frame, two symmetrical inclined intermediate rollers 7 and two symmetrical inclined side rollers 6, and the groove angle α of the inclined intermediate rollers 7 is 25 °; the groove angle β of the inclined side roller 6 is 60°. The roller frame is welded by the side pillar 2, the outer plate 3, the inner plate 4, the middle vertical plate 5 and the bottom frame 1, and the tops of the side pillar 2, the outer plate 3, the inner plate 4 and the middle vertical plate 5 are all There is a U-shaped groove, and the 6 shafts of the two inclined side rollers are respectively inserted into the U-shaped grooves at the top of the side pillar 2 and the side plate 4. The groove angle β is 60° to ensure the flexible operation of the side rollers. Two inclined intermediate rollers The shafts of the roller...

The invention discloses a belt conveyer four-linked-deep-groove upwards supporting roller group which is mainly applied to the transportation of mine materials. The structure of the invention comprises a supporting roller frame, two symmetrical lateral supporting rollers which are obliquely arranged and two symmetrical middle supporting rollers which are obliquely arranged, wherein, the groove angle of the obliquely arranged middle supporting roller is 25 degrees, and the groove angle of the obliquely arranged lateral supporting roller is 60 degrees. In the invention, the two obliquely arranged symmetrical supporting rollers are used to replace the prior flat arranged middle supporting roller and increases the groove angle of the two lateral supporting rollers at the same time, which increases the groove depth of the transportation section and the area of material flow section to improve the transporting capability of a conveyer and the friction coefficient of the materials and a conveyer belt, at the same time the transportation angle is improved with the maximum upwards transporting angle of 17 degrees, the maximum downwards transporting angle of 15 degrees, and the maximum upwards transporting angle of a deep-groove supporting roller can be 29 degrees while the maximum downwards transporting angle can be 25 degrees, which realizes the materials transportation with large inclined angle.
Description
technical field [0001] The present application belongs to material conveying machinery, in particular to belt conveyors. Background technique [0002] The "DTII general-purpose fixed belt conveyor" currently used in coal mines, the upper idler group is composed of an idler frame, a flat middle idler and two symmetrical inclined side idlers. There are two kinds of trough angles, 35° and 45°, the maximum inclination angle of the upward movement is 17°, and the maximum inclination angle of the downward movement is 15°, and has been widely used. Due to the limitation of section shape, it cannot adapt to larger transportation angle and transportation volume. Contents of the invention [0003] The purpose of this application is to solve the technical problem that the belt conveyor cannot be transported at a large inclination angle, and to provide a four-connected deep groove upper idler set for the belt conveyor. [0004] In order to achieve the above purpose, the application ...
