[0029] The shell 1 is composed of an upper expansion shell and a lower transport shell. The upper expansion shell of the shell 1 is an inverted trapezoidal structure. The decompression part 8 is arranged in the middle position of the upper expansion shell of the shell 1. The guide plate 84 is set at an inclined angle. The front and rear end surfaces of the guide plate 84 and the middle plate 81 are in contact with the front and rear inner walls of the shell 1. Through this arrangement, the decompression part 8 can hinder and reduce pressure on most of the materials entering the shell 1 and guide them; the height dimension of the guide block 4 is the same as the groove height dimension of the guide groove 2, and the outer end surface of the guide block 4 is in contact with the inner wall of the guide groove 2. Through this arrangement, the displacement stability of the guide block 4 is improved. The first buffer spring 5 is arranged on the inner side of the guide groove 2, and the first buffer spring 5 is arranged on the side of the guide block 4 away from the middle plate 81. Through this arrangement, the two sides of the deformed decompression part 8 can be buffered; the rotating block 85 is a circular block structure, and the rotating block 85 is inserted into the inner side of the rotating hole of the guide block 4. Through this arrangement, the guide plate 84 and the guide block 4 can be rotatably connected. The middle plate 81 and the fixed plate 9 are upper and lower The alignment setting, the limit guide rod 10 is composed of an upper damping rod and a lower limit block. The limit guide rod 10 is vertically set in the longitudinal direction. Through this setting, the displacement of the middle plate 81 can be guided and limited, so that the middle plate 81 can only move up and down. At the same time, the limit guide rod 10 can apply a damping effect to the buffer. The second buffer spring 11 is arranged between the upper end surface of the fixed plate 9 and the lower end surface of the middle plate 81. Through this setting, the displacement of the middle plate 81 can be buffered; the upper side of the middle plate 81 is fixedly connected with a buffer pad 82, through which the material falling on the middle plate 81 can be buffered, the outer side of the guide block 4 is fixedly connected with a connecting rod 6, and the other end of the connecting rod 6 is fixedly connected with a guide bar 7 on both sides of the pressure reducing part 8, the guide bar 7 is set at an inclined angle, the upper end side surface of the guide bar 7 is in contact with the inner wall of the shell 1, and the guide bar 7 is arranged on the upper side of the guide groove 2. Through this setting, the guide groove 2 exposed on both sides of the pressure reducing part 8 can be blocked to prevent the material from entering the guide groove 2.
[0030] Working process: The decompression operation of the decompression plate in the hopper above the belt conveyor for the conveyed material is as follows. Note 1: The limit guide rod 10 guided by the fixed plate 9 can guide the middle plate 81 of the decompression part 8 to move up and down, so that the middle plate 81 can only move up and down when the decompression part 8 blocks and guides the falling materials, and the middle plate 81 that moves up and down is buffered in the middle by the second buffer spring 11 (the buffer is damped by the limit guide rod 10). Note 2: When the decompression part 8 is subjected to upper pressure, the plate 81 will move downward, and the downward pressure of the middle plate 81 will cause the guide plates 84 on both sides to expand to both sides, and push the guide blocks 4 on both sides to move guided by the shaft rod 3, The buffer spring 5 is squeezed, and the two sides of the pressure reducing part 8 can be buffered by the first buffer springs 5 on both sides. It can be known from Notes 1 and 2 that when the pressure reducing part 8 contacts with the material, the pressure on the pressure reducing part 8 itself can be reduced by its own deformation and the buffering of the auxiliary structure. When the material is conveyed downward through the shell 1, most of it will fall on the pressure reducing part 8. The obstruction and guidance of the pressure reducing part 8 can prevent the material conveyed downward from being directly pressed onto the conveying belt on the lower side. Through the above operation, the pressure reducing plate in the hopper above the belt conveyor can reduce the pressure and divert the material transmitted downward, so that the conveying belt that receives the falling material can maintain smooth operation, thereby avoiding the occurrence of scaffolding at the lower discharge port of the hopper.
