Detailed Description of the Embodiment

[0023] To make the technical personnel in the technical field more clear and definite about the technical solution of the utility model, the following further describes the utility model in detail in combination with the embodiments and the drawings, but the embodiments of the utility model are not limited thereto.

[0024] Such as Figures 1-4As shown in the figure, this embodiment provides a full-section belt-breaking arrest device for an upward-conveying trough-shaped conveyor belt, which includes a conveying frame 1, conveying rollers 2 installed along the length direction of the conveying frame 1 to support the conveyor belt, and a conveyor belt on top of the conveying rollers 2. An installation frame 3 is fixed between the two sides of the conveying frame 1 and above the conveyor belt. A lower support plate 4 is fixed to the inner bottom of the conveying frame 1 below the installation frame 3. A groove 5 matching the conveyor belt is formed at the top of the lower support plate 4. A hydraulic cylinder 7 is vertically installed at the middle position of the top of the installation frame 3. An upper pressing block 6 is vertically slidably installed between the two sides of the installation frame 3. The bottom of the upper pressing block 6 is engaged with the top of the lower support plate 4. The output end of the hydraulic cylinder 7 is connected to the upper pressing block 6. Slopes are symmetrically arranged at the bottom ends on both sides of the upper pressing block 6. Scrapers 15 are symmetrically attached to both sides of the upper pressing block 6. The bottom ends of the two groups of scrapers 15 are attached to each other. A rotating rod 14 is fixed to the top of each scraper 15. Above the rotating rods 14, mounting rods 13 parallel to the length direction of the upper pressing block 6 are provided, and the rotating rods 14 are rotatably installed on the mounting rods 13. An elastic reset member for controlling the lifting of the mounting rod 13 is provided at the top of the upper pressing block 6.

[0025] Overall working principle: When the detection system detects a full-section break of the conveyor belt, the hydraulic cylinder 7 is controlled to start. The hydraulic cylinder 7 drives the upper pressing block 6 to move downward. The scraper 15 will first pass through the material and contact the surface of the conveyor belt, and will continue to extend as the hydraulic cylinder 7 extends. Under the control of the elastic reset member, at this time, the upper pressing block 6 continues to move downward, while the scraper 15 is squeezed to both sides, and the scraper 15 opens to both sides, pushing the material to the outside and cleaning the extrusion position. After the two groups of scrapers 15 are fully unfolded and cleaned, at this time, the upper pressing block 6 will contact the surface of the conveyor belt and cooperate with the lower support plate 4 for extrusion and positioning.

[0026] In this embodiment, rotating rollers 9 are rotatably installed on both inclined surfaces and the bottom plane inside the groove 5, and the tops of the rotating rollers 9 are in contact with the bottom of the conveyor belt.

[0027] Local working principle: The use of the rotating rollers 9 can provide a supporting force for the bottom of the conveyor belt and prevent friction and wear between the conveyor belt and the lower support plate 4.

[0028] In this embodiment, anti-slip patterns are evenly arranged inside the groove 5, and the anti-slip patterns are parallel to the length directions of the sides and the bottom of the groove 5.

[0029] Local working principle: The setting of the anti-slip patterns can increase the frictional resistance between the conveyor belt and the groove 5 and improve the positioning stability of the conveyor belt.

[0030] In this embodiment, sliding rods 8 are vertically slidably installed at both ends of the top of the installation frame 3, and the bottom ends of the sliding rods 8 are fixedly connected to the top of the upper pressing block 6.

[0031] Local working principle: The setting of the sliding rod 8 ensures the stability of the vertical sliding of the upper pressing block 6.

[0032] In this embodiment, rubber strips 16 are provided along the length direction at the bottom of the scraper 15, and the sides of the two groups of rubber strips 16 are mutually attached.

[0033] Local working principle: The use of the rubber strips 16 can avoid abrasion on the top of the conveyor belt and facilitate the outward opening of the scraper 15.

[0034] In this embodiment, the elastic reset member includes a through groove 10, a slider 11 and a spring 12. The through groove 10 is opened at the middle position of the upper pressing block 6 and penetrates through both sides of the upper pressing block 6. A slider 11 is vertically slidably arranged inside the through groove 10, and the bottom end of the slider 11 is attached to the inner bottom of the through groove 10. A spring 12 is provided between the top of the slider 11 and the top of the through groove 10.

[0035] Local working principle: After the bottom of the scraper 15 is subjected to resistance, as the upper pressing block 6 continues to move downward, the scraper 15 will move upward. At this time, the slider 11 moves upward inside the through groove 10 and squeezes the spring 12, ensuring that the upper pressing block 6 can slide out from between the two groups of scrapers 15. After the conveyor belt is repaired, the use of the spring 12 can facilitate the reset of the scraper 15.

[0036] In this embodiment, the springs 12 are symmetrically arranged at both ends of the top of the slider 11, and the length of the slider 11 is equal to the thickness of the upper pressing block 6.

[0037] Local working principle: Since the length of the slider 11 is equal to the thickness of the upper pressing block 6, the mounting rod 13 will slide along the surface of the upper pressing block 6, ensuring the stability of the slider 11 during sliding.

[0038] The above is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and its concept of the present utility model, makes equivalent substitutions or changes, all belong to the protection scope of the present utility model.
