[0004] To achieve the above object, the utility model is implemented by the following technical scheme:

[0005] A kind of belt conveyor arc turning device, including base, at least one group of carrier roller assembly installed in carrying layer and at least one group of return assembly installed in idle layer, the carrier roller assembly includes carrier roller frame, vertical roller, compression roller and bearing carrier roller, the vertical roller and the compression roller are installed in the two sides of the carrier roller frame, the bearing carrier roller is arranged in the bottom side of the carrier roller frame with U type, and the mounting angle of the bearing carrier roller with the carrier roller frame is adjustable, and the bearing carrier roller of belt conveyor turning device arc turning place inner arc one side is higher than the bearing carrier roller of outer arc one side.

[0006] Further, the bearing carrier roller is three-union carrier roller, four-union carrier roller, five-union carrier roller or six-union carrier roller, and the two bearing carrier rollers at both ends are installed on the two columns of the carrier roller frame by pin shaft.

[0007] Further, the column can be fixedly installed by lifting on the carrier roller frame, and the column is in the vertical ground direction.

[0008] Due to the adoption of the above technical scheme, the utility model has the beneficial effects that:

[0009] The arc line turning device of the belt conveyor effectively prevents the material from scattering at the turning position due to the higher bearing carrier roller on the inner arc side than the bearing carrier roller on the outer arc side. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0013] The utility model will be further explained in connection with the drawings and examples.

[0014] As shown in Figure 1 and Figure 2 An arc line turning device of a belt conveyor, comprising a base 1, at least one group of roller assemblies 2 installed on a carrying layer Y and at least one group of return assemblies 3 installed on an empty layer K, the roller assembly 2 comprises a roller frame 201, an upright roller 202, a compression roller 203 and a bearing carrier roller 204, the upright roller 202 and the compression roller 203 are installed on both sides of the roller frame 201, the bearing carrier roller 204 is arranged in a U shape at the bottom side of the roller frame 201, and the bearing carrier roller 204 is a three-roller carrier, a four-roller carrier, a five-roller carrier or a six-roller carrier.

[0015] The installation angle a, b, c, d of the bearing carrier roller 204 and the roller frame 201 is adjustable, the roller frame 201 comprises two upright columns 205 at both ends, the two bearing carrier rollers 204 at both ends are installed on the two upright columns 205 of the roller frame 201 through the pin shaft 206, and the angle a, b of the two bearing carrier rollers 204 at both ends and the two upright columns 205 is adjustable.

[0016] The load roller 204 on the inner side of the arc of the belt conveyor turning device is higher than the load roller 204 on the outer side of the arc. Preferably, the column 205 on the inner side of the arc is raised to raise the load roller 204 mounted on the column 205, and after the load roller 204 is raised to a specified height, the angle between the column 205 and the load roller 204 is adjusted so that the column 205 is perpendicular to the ground, and the column 205 is fixed. As shown in Figure 2 before the raising, the angle between the column 205 on the inner side of the arc and the load roller 204 is a=35°, and after the raising, the angle between the column 205 on the inner side of the arc and the load roller 204 is b=21°, the angle is reduced, the column 205 is always kept perpendicular to the ground, the equipment occupies a small space, and the belt conveyor arc turning device can be smoothly installed in an extremely limited environment, and large-angle arc turning operation of the belt conveyor is realized.

[0017] Correspondingly, the angle c, d between the column 205 on the outer side of the arc and the load roller 204 can also be adjusted.
