[0045] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0046] like Figures 1 to 6 As shown, the belt conveyor provided in this embodiment includes a track base 1, a driven wheel group 2, a belt 3, a lifting mechanism 4 and a second driving component 5; the driven wheel group 2 is installed on the track base 1; the belt 3 is wound around the driven wheel group 2, and the belt 3 includes a transmission section 31 and a circulation section 32, the transmission section 31 and the circulation section 32 are connected end to end, and the transmission section 31 is located above the circulation section 32; the lifting mechanism 4 includes a first driving component, a top plate 41 and a first tensioning wheel 42, the top plate 41 is installed at the output end of the first driving component, the top plate 41 abuts against the transmission section 31, the first tensioning wheel 42 is installed on the top plate 41, the first tensioning wheel 42 abuts against the circulation section 32, and the first driving component can drive the top plate 41 to lift the transmission section 31 in the vertical direction; the second driving component 5 is used to drive the belt 3 to rotate around the driven wheel group 2.

[0047] Specifically, the material is placed on the conveying section 31. After the belt conveyor is started, the second drive assembly 5 drives the belt 3 to rotate around the driven wheel group 2, thereby conveying the material; when the horizontal height of the material needs to be raised, the first drive assembly drives the top plate 41 to lift the conveying section 31 in the vertical direction, and the conveying section 31 is raised to a preset horizontal height so that the material can be processed or assembled at the preset horizontal height. When the conveying section 31 is lifted, the circulation section 32 has a tendency to follow the rise. Since the first tensioning wheel 42 abutting the circulation section 32 can rise with the top plate 41, the circulation section 32 can also rise to prevent the belt 3 from being torn; when the horizontal height of the conveying section 31 needs to be lowered, the first drive assembly drives the top plate 41 to descend to a preset horizontal height in the vertical direction, and the first tensioning wheel 42 abutting the circulation section 32 can descend with the top plate 41. The first tensioning wheel 42 tightens the belt 3 to prevent it from being loose.

[0048] In this embodiment, the first tensioning wheel 42 can rise and fall in the vertical direction following the top plate 41 , so that the belt 3 can always be kept taut and prevented from breaking during the process of the horizontal height of the conveying section 31 .

[0049] In this embodiment, the second driving assembly 5 includes a motor and a transmission wheel. The transmission wheel is sleeved on the output end of the motor and is connected to the belt 3. The motor drives the transmission wheel to drive the belt 3 to rotate around the driven wheel assembly 2.

[0050] Optionally, a vertical guide rail 6 is provided between the track base 1 and the top plate 41, and the vertical guide rail 6 is used to vertically guide the top plate 41. The vertical guide rail 6 can guide the top plate 41 to prevent the top plate 41 from deviating from a preset sliding direction.

[0051] Optionally, the first driving component includes a first driving member 43 and a guide wheel 44. The first driving member 43 is installed on the track base 1 in the horizontal direction. An inclined groove 4101 is provided on the top plate 41. The guide wheel 44 is connected to the output end of the first driving member 43 and is accommodated in the inclined groove 4101. The first driving member 43 is used to drive the guide wheel 44 to move in the horizontal direction. The guide wheel 44 can lift the top plate 41 in the inclined groove 4101.

[0052] The track base 1 extends in the horizontal direction. In this embodiment, the first driving member 43 is horizontally installed on the track base 1 to fully utilize the space in the length direction of the track base 1; the guide wheel 44 is accommodated in the inclined groove 4101. When the guide wheel 44 slides in the inclined groove 4101, the force generated by the guide wheel 44 on the top plate 41 can be decomposed into a vertical component and a horizontal component. Due to the guiding effect of the vertical guide rail 6 on the top plate 41, the top plate 41 can only move in the vertical direction. Therefore, when the first driving member 43 drives the guide wheel 44 to move in the horizontal positive direction, the guide wheel 44 slides to the bottom of the inclined groove 4101, and the top plate 41 rises. When the first driving member 43 drives the guide wheel 44 to move in the horizontal reverse direction, the guide wheel 44 slides to the top of the inclined groove 4101, and the top plate 41 descends. The aforementioned horizontal positive direction and horizontal reverse direction are two opposite directions, one of which is the same as the material conveying direction, and the other is opposite to the material conveying direction.

[0053] In some other embodiments, the first driving member 43 is installed on the track base 1 along the vertical direction.

[0054] In this embodiment, the first driving member 43 is a cylinder. In some other embodiments, the first driving member 43 is a linear motor or a linear electric cylinder.

The horizontal guide rail 7 guides the mounting plate 45 to prevent the guide wheel 44 mounted on the mounting plate 45 from deviating from the preset sliding direction.

[0056] Optionally, the first drive assembly further includes a spring 46, which is disposed between the first drive member 43 and the mounting plate 45, and is used to elastically push the mounting plate 45. The power transmitted by the spring 46 can buffer the power output by the first drive member 43 and prevent the mounting plate 45 from starting suddenly.

The spring 46 is used to push the second limit member 49 so that the second limit member 49 is always in contact with the side of the connecting platform 451 away from the first limit member 48. When the output end of the first driving member 43 extends out, the connecting shaft 47 moves synchronously. At this moment, the connecting platform 451 is separated from the first limit member 48 and the spring 46 is compressed. Afterwards, since the spring 46 has elastic potential energy to restore its original state, the spring 46 pushes the second limit member 49 and the connecting platform 451 toward the first limit member 48.

[0059] Optionally, the track base 1 is provided with an avoidance opening 11 , the connecting platform 451 passes through the avoidance opening 11 , the first driving member 43 and the mounting plate 45 are respectively located on both sides of the track base 1 , and the mounting plate 45 , the top plate 41 and the belt 3 are located on the same side of the track base 1 .
