The limiting sliding sleeve is fixedly connected to the conveyor chain, the limiting sliding sleeve is movably connected to the mounting frame, the first fixed pulley and the adjusting shaft are rotatably connected to the mounting frame, the first fixed pulley is located above the limiting sliding sleeve, and the adjusting shaft is located below the limiting sliding sleeve.

[0006] One end of the rope is wound around the first fixed pulley and fixedly connected to the limiting sliding sleeve, and the other end of the rope is wound around the adjusting shaft for at least three turns and then fixedly connected to the limiting sliding sleeve.

[0007] Preferably, the conveying chain includes a left conveying chain and a right conveying chain. In each adjusting device, the number of the first fixed pulley, the limiting sleeve and the rope is two, the number of the adjusting shaft is one, and the two ropes in each adjusting device are wound around the same adjusting shaft.

[0012] Beneficial effect: Compared with the prior art, the utility model forms a lifting mechanism through a rope, a first fixed pulley, and an adjusting shaft. When the height of the conveying chain needs to be adjusted, the adjusting shaft is rotated by a wrench to pull the rope, thereby driving the limiting sliding sleeve columns connected to the two ends of the rope to perform lifting movements. At the same time, since the two ends of the left and right conveying chains are respectively driven by the same adjusting shaft, the left and right conveying chains can always maintain the same height. By converting torque into linear motion, adjustment is more convenient and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS
