When the distance between the two pulleys 3 needs to be adjusted, it is only necessary to manually hold the turntable 5 to drive the adjusting rod 4 to rotate, and at the same time, the adjusting rod 4 and the pulley 3 fixed thereon can be moved in the upper and lower directions of the limit plate 21.

[0024] When it is necessary to increase the adjustable range of the rope length, three, four, ..., or other number of adjusting rods 4 can be provided on the limiting plate 21 , and the design can be based on actual engineering needs.

[0025] The utility model provides a rope length adjustment device for a belt conveyor, which further comprises a housing 2 . The housing 2 comprises two upper and lower limit plates 21 . A pulley 3 is arranged inside the housing 2 .

[0026] A rotary disk 5 is fixed to one end of the adjusting rod 4 away from the housing 2 .
