[0019] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0020] As Figure 1-2As shown in the figure, a device for preventing materials from falling into the counterweight drum includes a counterweight drum 12 and a belt 3 wound around the outside of the counterweight drum 12. It also includes a bracket, which consists of four columns 1 and two groups of crossbars 2. Each group of crossbars 2 includes at least three parallel ones. The crossbars are perpendicular to the columns 1. The two groups of crossbars 2 are parallelly arranged and passed through the vertical section of the belt 3. The two ends of the crossbars 2 are respectively fixedly connected to the columns 1. A horizontal baffle belt 4 is arranged on the bottom surface of the uppermost crossbar 2. A fastening bolt 8 is arranged between the horizontal baffle belt 4 and the crossbar 2. Upper connectors 9 and lower connectors 10 are respectively arranged between the upper and lower surfaces of the horizontal baffle belt 4 and the crossbar 2. The upper connectors 9 and lower connectors 10 are connected to the horizontal baffle belt 4 and the crossbar 2 through the fastening bolt 8. The two ends of the horizontal baffle belt 4 are attached to the inner wall of the belt 3. The horizontal baffle belt 4 is perpendicular to the inner wall of the vertical section of the belt 3. Herringbone cleaners 5 are respectively arranged on the two groups of crossbars 2. The central axis of the herringbone cleaner 5 is parallel to the column 1. The end angle direction of the herringbone cleaner 5 is opposite to the movement direction of the belt 3, that is, the end angle directions of the two herringbone cleaners 5 are opposite. The rubber surface of the herringbone cleaner 5 is attached to the inner wall of the belt 3. An adjusting screw 6 is passed through the crossbar 2 and connected to the herringbone cleaner 5. A nut 7 is arranged at the end of the adjusting screw 6 away from the herringbone cleaner 5. A spring 11 is arranged between the nut 7 and the crossbar 2.

[0021] When the belt conveyor is running, the falling materials are blocked by the horizontal baffle belt 4 to prevent large materials from falling into the counterweight drum 12 and getting stuck between the belt 3 and the counterweight drum 12, causing the belt 3 to run off or the belt 3 to be perforated. Fine materials fall on the horizontal baffle belt 4 during the operation. Some fine materials slide through the gap between the horizontal baffle belt 4 and the running belt 3 and are cleaned to the outside of the counterweight drum 12 by the herringbone cleaner 5 below to prevent them from entering the counterweight drum 12 facility.

[0022] Adjustment and maintenance method: When there is a lot of material accumulation above the horizontal baffle belt 4, clean it after stopping the machine. When the gap between the horizontal baffle belt 4 and the running belt 3 exceeds 20 mm, replace the horizontal baffle belt 4 with a waste belt. The herringbone cleaner 5 is connected by a spring 12 and an adjusting screw 6. When the rubber of the herringbone cleaner 5 is worn and there is an obvious gap between the herringbone cleaner 5 and the running belt 3, the rubber of the herringbone cleaner 5 should be replaced.
