[0018] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0019] Reference Figure 1-3The utility model embodiment of an anti-overflow device comprises: a conveyor belt 1, a fixed rod 2 is arranged on the right side of the conveyor belt 1, a bottom plate 3 is fixedly connected to the bottom of the fixed rod 2, the conveyor belt 1 is located above the bottom plate 3, a flap assembly is arranged on the left side of the fixed rod 2, the flap assembly is at an angle of 60 degrees with the conveyor belt 1, the flap assembly comprises a large round tube 4, an iron plate 5, a small round tube 6 and a positioning fixing pin 7, the right side wall of the large round tube 4 is rotatably connected to the fixed rod 2, an iron plate 5 and a small round tube 6 are fixedly connected to the circumferential surface of the large round tube 4, the iron plate 5 is located above the conveyor belt 1, the iron plate 5 is rectangular, and occupies three quarters of the length of the large round tube 4, when there are debris or large pieces on the conveyor belt 1 stuck in the chute, When the material is piled up, the iron plate 5 is lifted up, thereby causing the large round tube 4 and the small round tube 6 to rotate. The small round tube 6 is located on the left side of the conveyor belt 1. The iron plate 5 and the small round tube 6 are arranged in parallel. A positioning fixing pin 7 is fixedly connected to the small round tube 6. A signal sensor device 8 is fixedly connected to the top of the bottom plate 3. The signal sensor device 8 is small in size and sensitive in signal sensing. It is connected to the external control system and can transmit signals to the control system and stop the conveyor belt 1. The signal sensor device 8 is located in front of the positioning fixing pin 7.

[0020] Working principle: Materials are transported on the conveyor belt 1. If there are debris or large pieces of materials stuck in the chute, the materials will pile up. At this time, the piled materials will gather quickly and lift up the upper iron plate 5. The angle of the iron plate 5 will increase. At this time, the large round tube 4, the small round tube 6 and the adjustment fixing pin 7 will rotate. The adjustment fixing pin 7 will touch the signal sensor 8. The signal sensor 8 will generate a signal and transmit it quickly to indicate a fault, thereby causing the conveyor belt 1 to stop urgently to prevent material overflow, so as to achieve timely discovery and the operator can clean up the debris or large pieces of materials in time to avoid material overflow.
