Description

TECHNICAL FIELD

[0001] The present application belongs to the field of continuous conveying of bulk materials, and particularly relates to a self-adaptive compression wheel set for a compression device of a compression belt conveyor. BACKGROUND

[0002] The compression belt conveyor is used for large-angle continuous conveying of bulk materials, and the large-angle continuous conveying of the bulk materials is achieved by exerting pressure on the bulk materials by a cover belt. The pressure exerted on the bulk materials by the cover belt is partly provided by the self-gravity of the cover belt and partly provided by a compression device. At present, the compression device exerts pressure on the cover belt by a plurality of compression roller sets installed thereon, such as CN203306593U and CN207030175U. The compression rollers of the compression roller set are installed on a compression roller frame in the form of ordinary carrier rollers and provide pressure on the cover belt by being pressed against the cover belt by the compression roller frame. The compression roller set using carrier rollers to press against the cover belt has the following problems:

[0003] 1. During the conveying of the bulk materials by the compression belt conveyor, the conveying amount of the bulk materials and the particle size of the bulk materials are constantly changing, which causes the enclosed space between the cover belt and the carrier belt to constantly change, resulting in random transverse displacement of the cover belt. The transverse arrangement of the compression roller axes of the compression roller sets in the compression devices of patents CN203306593U and CN207030175U only allows the cover belt to move in the longitudinal direction; however, in the transverse direction, the cover belt is affected by the frictional force generated by the contact pressure between the compression rollers and the cover belt, and it is difficult for the cover belt to move smoothly, and this frictional force also accelerates the wear of the compression rollers and the cover belt.

[0004] 2. During the adjustment of the positions and angles of the compression rollers of the compression roller sets of the compression devices of patents CN203306593U and CN207030175U, the end faces of the carrier rollers are easily in contact with the conveying belt, which causes scratches on the cover belt and seriously affects the safe operation of the compression belt conveyor. SUMMARY

[0005] In view of the deficiencies of the prior art, the purpose of the present application is to provide a self-adaptive compression wheel set for a compression device of a compression belt conveyor.

[0006] The technical scheme adopted by the present application is as follows: a self-adaptive compression wheel set for a compression device of a compression belt conveyor, which comprises universal wheels, a guide mechanism, springs, and a compression wheel frame, the universal wheels are installed below the guide mechanism in sliding connection with the compression wheel frame, springs are arranged between the compression wheel frame and the guide mechanism, the upper end face of the spring is in contact with the compression wheel frame, the lower end face of the spring is in contact with the pressure receiving surface of the guide mechanism, and the springs provide pressure to make the wheel bodies of the universal wheels tightly adhere to the surface of the cover belt.

[0007] In the above scheme, the guiding mechanism consists of a universal wheel mounting base, a guide sleeve, and a guide column. The universal wheel mounting base is provided with bolt holes corresponding to the mounting bolt holes on the universal wheel, and the universal wheel is fixed to the guiding mechanism by bolt connection. The guide sleeve and the guide column are arranged concentrically and are respectively welded to the universal wheel mounting base, while the universal wheel mounting base is in contact with the lower end face of the spring.

[0008] In the above scheme, the guiding mechanism consists of a caster wheel mounting base, a guide column, and a spring seat. The caster wheel mounting base is provided with bolt holes corresponding to the mounting bolt holes on the caster wheel. The caster wheel is fixed to the guiding mechanism by bolt connection. The guide column is welded to the caster wheel mounting base. After the guide column passes through the two guide holes of the pressure roller frame and the spring seat and spring between the two guide holes, the spring seat contacts the lower end face of the spring. After allowing sufficient travel for the caster wheel, the spring seat is fixed to the guide column.

[0009] In the above scheme, the guide post slides within the guide hole located in the pressure roller frame.

[0010] In the above scheme, a limiting device is installed on the pressure roller frame to restrict the swing angle of the caster wheel.

[0011] In the above scheme, a connecting piece is also welded onto the pressure roller frame for hinged connection with the pressure belt frame of the pressure belt device to allow for oscillation to adapt to changes in the shape of the cover belt.

[0012] In the above scheme, the connecting component is a hinge bracket.

[0013] In the above scheme, the connecting component is a hinge shaft hole.

[0014] In the above scheme, a guide limiting member is connected to the top of the guide mechanism to prevent the guide mechanism from disengaging from the pressure roller frame. The beneficial effects of this invention are: the adaptive pressure roller assembly for the belt pressing device of a belt conveyor includes casters installed below the guide mechanism. The swinging motion of the casters minimizes the frictional restriction on the lateral movement of the conveyor belt by the pressing device, reducing the resistance to the lateral movement of the cover belt, making the lateral movement of the cover belt more free, and improving the smoothness of the cover belt's movement; replacing idlers with casters completely avoids the problem of the outer edge of the idler side of conventional belt pressing devices easily scratching the cover belt, significantly improving the operational safety and reliability of the belt conveyor; springs are provided between each caster and the pressure roller frame, which helps to balance the pressure between each caster, ensuring good contact between each caster and the cover belt and effectively transmitting the pressing force.
