[0035] Reference Figure 2The conveyor belt mechanism includes a circulating conveyor belt support 22, which supports a stone conveyor belt 23 and a recycling conveyor belt 24. The stone conveyor belt 23 is mounted on top of the circulating conveyor belt support 22, conveying stones sliding off the rail steel 12 to the recycling conveyor belt 24. The recycling conveyor belt 24 then conveys the stones to the rear for further crushing and screening. Two stone baffles 25 are fixedly connected to the top of the circulating conveyor belt support 22.
