DETAILED DESCRIPTION

[0022] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0023] See also Figure 1-2The belt conveyor roller structure that is convenient for lifting and adjusting comprises a roller mounting seat 4, on the top of which a roller 1 is rotatably mounted through a bearing seat 3 and a bearing 2; the bottom center of the roller mounting seat 4 is connected to the piston rod 12 of a lifting cylinder 16 through a piston rod connecting seat 11, and the lifting cylinder 16 is fixedly mounted on a frame plate 8; a lifting guide mechanism 13 is installed between the roller mounting seat 4 and the frame plate 8, and the lifting guide mechanism 13 is symmetrically distributed on both sides of the piston rod 12; a synchronous locking mechanism 14 is arranged outside the lifting guide mechanism 13 and between the roller mounting seat 4 and the frame plate 8. The roller structure can be conveniently adjusted in height, so as to adjust the support height of the conveying belt, so as to ensure that the belt can be adjusted in time when it deviates, so as to ensure the normal conveying process of the belt. When the roller needs to be adjusted, the roller mounting seat 4 on the top is driven by the lifting cylinder 16, and the roller 1 on the top is driven to lift and lower by lifting and lowering the roller mounting seat 4, thereby realizing the adjustment of the belt height.

[0024] Further, an auxiliary mounting seat 17 is provided at the top of the roller mounting seat 4 and at the side of the roller 1. The auxiliary mounting seat 17 can be used to install a motor, and then the main shaft of the roller 1 is driven to rotate by the motor.

[0025] Further, the lifting cylinder 16 is mounted on the frame plate 8 via a cylinder fixing seat 18. The cylinder fixing seat 18 ensures reliable fixing and installation of the lifting cylinder 16, thereby ensuring the stability of the lifting cylinder 16.

The above-mentioned lifting guide mechanism can ensure stability during the lifting process. During the lifting adjustment process, the guide rod 10 can slide inside the guide sleeve 9, thereby ensuring the stability and reliability of the roller mounting seat 4 during the lifting process.

[0027] Furthermore, the synchronous locking mechanism 14 includes a locking screw 7, the top end of which is hinged to the bottom end of the roller mounting seat 4 through a ball hinge 6, and the locking screw 7 is threadedly matched with the threaded sleeve on the frame plate 8. The synchronous locking mechanism 14 can ensure that the height of the roller mounting seat 4 is locked after the height adjustment is completed. During the working process, the locking screw 7 is synchronously rotated during the lifting process of the lifting cylinder 16, so that the locking screw 7 is synchronously lifted and lowered.
