The top shell 1 is fixedly installed above the chute 9, and the side shells 4 are symmetrically arranged inside the chute 9. The rotating shaft 7 is rotatably connected between the side shells 4, and the flap 6 is fixedly connected to the outside of the rotating shaft 7. The upper shell 2 and the lower shell 5 are fixedly installed inside the chute 9, the sensor base 3 is installed on the side shell 4, the sensor base 3 is provided with an induction switch 8, and the flap 6 is provided with a limit feeler 10.

[0021] It should be noted that: a square hole is cut above the normal material level of the hopper, where the material cannot be flushed but can be reached after blocking, the top shell 1 is installed on the opening of the square chute 9, and then the flap 6 and the rotating shaft 7 are installed on the side shell 4 facing the inside of the hopper. When the rear end of the sensor base 3 is against the side plate of the hopper, the upper shell 2 is welded to the side plate of the hopper, and the flap 6 can easily rotate around the rotating shaft 7. Finally, the induction switch 8 is connected to the pull rope switch of the belt conveyor or the power supply of the machine-side operation box. When the material rises and squeezes the flap 6, the flap 6 rotates around the rotating shaft 7, and the limit feeler 10 welded on the flap 6 rotates synchronously with the flap 6 and touches the induction switch 8 at the same time, sending a stop signal to make the belt conveyor stop urgently.

[0022] See also Figures 1 to 3 , the rear end of the sensor base 3 is against the hopper side plate, and the upper shell 2 is welded to the hopper side plate;

[0023] It should be noted that the rear end of the sensor base 3 is against the hopper side plate, so that the sensor base 3 can be stably fixed on the hopper side plate, and is not easy to shake or shift, which ensures that the induction switch 8 can work stably and is firmly and conveniently welded and fixed;

[0024] See also Figures 1 to 3 , the top shell 1, the upper shell 2, the side shell 4 and the lower shell 5 are all welded and fixed to the chute 9;

[0025] It should be noted that: welding fixation ensures the stability and reliability of the device structure;

[0026] See also Figures 1 to 3 , both the upper shell 2 and the sensor base 3 are provided with openings, and the openings of the upper shell 2 and the sensor base 3 are processed by taper wire;

[0027] It should be noted that the openings are taper-threaded to facilitate the passage and fixation of cables or other connectors;

[0028] See also Figures 1 to 3 , the flap 6 and the rotating shaft 7 are fixed by welding;

[0029] It should be noted that: it is ensured that the flap 6 can stably rotate around the rotation axis 7;

[0034] The working principle of the belt conveyor chute blockage alarm trip device provided by the utility model is as follows: the device is mainly composed of a top shell 1, an upper shell 2, a sensor base 3, a side shell 4, a lower shell 5, a flap 6, a rotating shaft 7, a chute 9, an induction switch 8 and a limit feeler 10 and other components. During the operation of the belt conveyor, the flap 6 easily rotates around the rotating shaft 7 to ensure that the material passes through the chute 9 smoothly. When the material accumulates in the chute 9 and causes blockage, the material rises and squeezes the flap 6, causing it to rotate around the rotating shaft 7. At the same time, the limit feeler 10 welded on the flap 6 also As the flap 6 rotates synchronously, once the limit feeler 10 touches the induction switch 8 installed on the sensor base 3, the induction switch 8 immediately sends a signal, and the signal is transmitted to the pull rope switch of the belt conveyor or the power supply of the machine-side operation box through the control system, triggering a stop command to make the belt conveyor stop urgently. During the whole process, various components of the device work together to realize real-time monitoring of the blockage of the chute 9 and automatic alarm tripping function. Through this mechanism, the device can effectively prevent the occurrence of problems such as material overflow and equipment damage, and ensure the safe and stable operation of the belt conveyor.
