Tilt grain conveyor , when the belt is pulled off due to an accident , the belt material , and to produce it at the decline clogging . To prevent pulling up the rear of the
conveyor decline required to set traps for 90 degree turn conveyor broken belt protection. Role trap is broken belt , the automatic action to seize the conveyor belt
The conveyor belt to stop. It therefore requires quick response, there is as small as possible braking time and braking distance. In normal operation the belt conveyor belt is
not worn , no additional resistance , without reducing the productivity of the conveyor . Material filled extent and reliability of its work without the belt
Conveyor installation angle impact . Trap can be used , such as a wedge and wheel stop mode .
1 ) It is 90 degree conveyor a wedge-shaped trap consists of two rollers mounted on brackets , guide ramps , locking mechanism and glide board composed . When pulled off the conveyor belt ,
detected by the speed sensor , and to disengage the locking device , slide the bracket down the conveyor belt was caught between the wedge and skateboards
. Completion of the conveyor belt arresting work .
2 ) It consists of upper and lower rollers catcher wheel brake , limit switches , spring preload and compression pulley components. The upper and lower sides of the belt brake
wheel grip , which can be rotated about its axis relative to the conveyor belt for rotation without sliding . When broken belt , the conveyor and material gravity is run by
upward
Into sliding down due to the brake drum rotates in only one direction can not be rotated in reverse direction , the brake wheel and the belt slip , slide under the action of
friction , to rotate with the wheel brake lever , two wheel brake soon the conveyor belt grip , played the role of conveyor arrest . In braking delivery
With the same limit switch signals .
