According to the description of a mining belt conveyor frame with a material drop buffer structure disclosed on the patent website (authorization announcement number: CN 215905227 U), "The utility model discloses a mining belt conveyor frame with a material drop buffer structure, including a belt conveyor main frame, a material drop buffer structure is arranged at the tail of the belt conveyor main frame, and the material drop buffer structure includes a bracket body, a plurality of buffer strips arranged side by side are arranged in the middle of the bracket body, and the length direction of the buffer strips is parallel to the conveying direction of the belt conveyor, and a plurality of buffer rollers are arranged side by side on the outer side of the buffer strips located at the edge, and the rolling axis of the buffer rollers is perpendicular to the conveying direction of the belt conveyor. The buffer rollers on both sides are symmetrically arranged and the overall structure is an inverted trapezoidal structure with a wide top and a narrow bottom. The bottom of each buffer roller is connected to the bracket body through a roller seat with an adjustable inclination angle. The utility model can adjust the inclination angle of each buffer roller through the roller seat, so that the gradient change of the inclination angle of each buffer roller is adjusted according to the on-site conditions, which improves the stress state of the belt when it runs to the buffer bed and prolongs the service life of the buffer bed and the conveying belt."

In view of the above description, the applicant believes that the following problems exist: when the device is in use, a plurality of rubber buffer seats are arranged between the bracket body and the main frame of the belt conveyor. As shown in the figure, the rubber buffer seat includes a top cover, a bottom support and a rubber block. The top cover is threadedly connected to the bracket body by a stud welded on the top, and the bottom support is threadedly connected to the main frame of the belt conveyor by a stud welded on the bottom.
