The outer sides of both ends of the inner rotating column 15 are rotatably connected to the inner side of the bracket 17, which plays a role in stabilizing the material transportation of the conveying belt 14. The shape of the movable concave frame 9 is an inverted "concave" shape, and the shape of the blocking plate 10 is the same as that of the movable concave frame 9. The outer side of the blocking plate 10 slides on the inner side of the feed port 3, blocking the lower end of the baffle 11 and the upper end of the feed port 3. The ends are flush, which prevents the material from overflowing. The outer side of the main shaft of the second motor 18 is rotatably connected to the inner side of one end of the movable concave frame 9. The outer side of one end of the cylindrical rotating rod 19 is rotatably connected to the inner side of one end of the movable concave frame 9. The cylindrical rotating rod 19 is in the shape of a cylinder. The number of the knocking rods 20 is two rows, and the number of the knocking rods 20 in each row is several, which is convenient for crushing large pieces of material. The number of dust extraction holes 13 opened on the inner side of the upper end of the movable concave frame 9 is several, and the dust extraction holes 13, the inner side of the movable concave frame 9, the fan 21, and the dust conveying soft The tube 22 is connected to the inner side of the material processing device 1, and one end of the dust conveying hose 22 is fixedly connected to the inner side of the upper end of the material processing device 1, so that the dust generated when the material inside the movable concave frame 9 is knocked is transported to the inside of the material processing device 1.

It is convenient to squeeze the movable solid block 6 and the stop rod button 8 when the movable concave frame 9 moves to control the start and stop of the inner rotating column 15.

[0024] Working process: When the device is in use, the external power supply is energized. When the conveyor belt 14 transports the material normally, the first motor 16 fixedly connected to one side of the bracket 17 is started. The main shaft of the first motor 16 rotates to drive the inner rotating column 15 fixedly connected to the end of the main shaft to rotate. The outer sides of the two ends of the inner rotating column 15 are rotatably connected to the inner side of one end of the bracket 17, which has the effect of stabilizing the rotation of the inner rotating column 15. The lower end of the bracket 17 is fixedly connected to the ground. The conveyor belt 14 rotates to transport the material to the inside of the feeding port 3 opened on the inner side of the material processing device 1. When the material is blocked, the material gathers on the inner side of the lower end of the movable concave frame 9 and the front end of the blocking baffle 11. Under the thrust of the conveyor belt 14, The material squeezes the blocking baffle 11, and the movement of the blocking baffle 11 drives the movable concave frame 9 fixedly connected on the outside to move, and the movement of the movable concave frame 9 drives the material blocking plate 10 fixedly connected on one side to move, and the outer side of the material blocking plate 10 slides on the inner side of the feeding port 3, and the material blocking plate 10 prevents the material from overflowing. At the same time, when the movable concave frame 9 moves, the movable concave frame 9 drives the movable solid block 6 fixedly connected on one side to move, and the movement of the movable solid block 6 drives the limiting column block 5 fixedly connected on one side to move, and the limiting column block 5 squeezes the spring 7, and the spring 7 has the effect of resetting the movable solid block 6. When one side of the limiting column block 5 contacts the stop rod button 8 fixedly connected to the inner side of one end of the hollow rod 4, the stop rod button 8 is released. The button 8 sends a signal to the inner rotating column 15 to stop the movement of the inner rotating column 15. At this time, the metal detector 12 fixedly connected to the inner side of the upper end of the movable concave frame 9 detects whether there is metal inside the material. If there is metal, the metal is removed manually. If there is no metal, the second motor 18 fixedly connected to one side of the movable concave frame 9 is started. The main shaft of the second motor 18 rotates to drive the cylindrical rotating rod 19 fixedly connected to the end of the main shaft to rotate. The rotation of the cylindrical rotating rod 19 drives the knocking rod 20 fixedly connected to the outside to rotate. When the conveying belt 14 works normally, the knocking rod 20 is in a horizontal state and does not hinder the normal transportation of the material. The knocking rod 20 rotates to knock the material. At the same time, the materials are sorted. For example, coal is crushed, while large pieces of plastic are normally difficult to crush. Therefore, whether there is plastic is manually observed and cleaned. When the second motor 18 rotates, the fan 21 fixedly connected to the upper end of the movable concave frame 9 is started. The fan 21 draws air into the movable concave frame 9. The dust flows into the movable concave frame 9 from the dust extraction holes 13 opened on the inner side of the upper end of the movable concave frame 9. The dust is conveyed to the inside of the dust hose 22 through the fan 21 conveyor belt. The dust hose 22 is a soft tube body, which is convenient for the movement of the movable concave frame 9. The dust is transported from the inside of the dust hose 22 to the inside of the material processing device 1. The start-stop button 2 fixedly connected to one side of the material processing device 1 controls the inner rotating column 15.
