Second support wheel 42 is oppositely arranged, and both axis form an included angle A, and the scope of the included angle A is 120 °~160 °,
Multigroup support wheel 40 is used to support the conveyer belt 10, and the conveyer belt 10 in the presence of deadweight, do not propped up by its middle part
Support causes middle part V-shape to be showed so as to overall, to sinking to prevent that coal charge drops from both sides during transporting coal.
Both ends are respectively arranged with baffle plate 80 vertically for the driving wheel 20 and the driven pulley 30, and the baffle plate 80 is higher by institute
Surface 20cm~30cm of driving wheel 20 or the driven pulley 30 is stated, when sideslip occurs for the conveyer belt 10, the conveyer belt
10 can extrude the baffle plate 80.The drive system 50 connects the driving wheel 20, for driving the driving wheel 20 to operate, institute
State pull switch system 60 and connect the drive system 50, for controlling the work and shutdown of the drive system 50.
The sideslip adjustment control system 70 includes multiple pressure sensors 71, a deviation switch 72 and a controller 73,
Multiple pressure sensors 71 are respectively arranged on each baffle plate 80, specifically, the pressure sensor 71 is arranged at
The inner side of baffle plate 80, and positioned at the baffle plate 80 and the driving wheel 20 or the junction of the driven pulley 30, when the transmission
When sideslip occurs for band 10, the pressure sensor 71 on the baffle plate 80 can be extruded, the degree of the sideslip of conveyer belt 10 is not
