[0003] Traditional conveyors usually weld the adjustable leg beams and flat roller seats directly to the legs. This fixed structure easily causes interference between the conveyor belt and the beams or flat rollers during operation, thus affecting the normal operation of the conveyor. Therefore, in order to adapt to changes in roadway terrain and avoid the above problems, we propose an assembled belt conveyor with adjustable legs, which can achieve flexible height adjustment without causing interference between the conveyor belt and other components.

The side surface of the trough body of the lower leg is also provided with equidistant bolt holes. The upper leg and the lower leg on the same side are slidably adjusted and assembled and fixed through the adapted bolt holes, thereby achieving the effect of adjusting the height of the overall bracket. The lap plate is fixed to the two ends of the crossbeam, and the lap plate There are slot-shaped mounting through holes on both sides, and the slot-shaped mounting through holes of the lap plate are respectively adapted to the equally spaced bolt holes of the upper leg or the lower leg. The crossbeam is installed between the upper legs or the lower legs on both sides through the lap plate to avoid interference between the crossbeam and the conveyor belt of the conveyor. There are also slot-shaped mounting through holes on the side walls of the flat roller hanging ears, and the slot-shaped mounting through holes of the flat roller hanging ears are respectively adapted to the equally spaced bolt holes of the upper leg or the lower leg. The flat roller hanging ears are installed between the upper legs or the lower legs on both sides according to on-site requirements. Flat rollers are assembled on the flat roller hanging ears on both sides to support the conveyor belt, and the connecting bolts are adapted to the bolt holes of the upper leg and the lower leg for adjustment and fixing.

[0006] Optionally, the upper supporting legs, lower supporting legs and cross beam are all made of channel steel, and the flat roller hanging ears are made of angle steel.

[0007] Optionally, the groove body of the upper leg is larger than the groove body of the lower leg, and the groove bodies of the upper leg and the corresponding lower leg on the same side are in the same direction, and the lower leg is slidably sleeved in the groove body of the corresponding upper leg.
