The pull rope interlocking type coal blockage device capable of realizing rapid rework according to claim 1, wherein two symmetrical inclined plates of the blanking barrel (12) are provided with U-shaped notches at the top edges, two ends of the movable shaft (121) are welded at the tops of two sides of the U-shaped notches, and a gap is reserved between the middle part of the movable shaft (121) and the bottom edges of the U-shaped notches so as to facilitate smooth rotation of the turnover plate.
4. The pull rope interlocking type coal blockage device capable of realizing rapid rework according to claim 1, wherein one end of the pull rope (9) is connected with four steel wire ropes, and the four steel wire ropes are respectively connected to four corners of an inclined plate at an opening at the top end of the blanking barrel (12).
5. The use method of the pull rope interlocking type coal plugging device capable of being reworked quickly according to claim 1 is characterized in that the following three working states are switched according to the actual coal plugging condition of the blanking pipe (4):
s1, initial state: the pull rope (9) bears the self-weight tension of the blanking barrel (12), and the tension is not enough to start and stop the pull rope switch (8);
s2, starting and stopping states: when coal blockage occurs in the blanking pipe (4), coal in the square observation hole (5) is uniformly sprinkled into the V-shaped groove, the turnover plate (122) is switched between material receiving and material discharging in the blanking process, the turnover plate (122) generates short-time vibration, and the hollow iron ball II (124) is impacted and vibrated by the hollow iron ball I (123), so that the uniform coal breakage and the cleaning of the coal blockage are promoted; when the bearing weight in the blanking barrel (12) exceeds the start-stop pulling force requirement of the pull-cord switch (8), the blanking barrel (12) quickly falls, and a certain gap is reserved between the drawing plate (13) and the material receiving plate (18) and between the drawing plate and the jacking movable gas rod (17), so that the start-stop process of the pull-cord switch (8) is prevented from being stopped;
s3, a relaxed state: the pulling plate (13) is opened, so that the materials quickly fall onto the material receiving plate (18), the coal materials of the blanking barrel (12) are received, pressure is generated to lead the material receiving movable air rod (19) to descend, correspondingly, the lifting movable air rod (17) quickly ascends, the empty blanking barrel (12) is lifted to the height of tight fit of the hollow iron ball I (123) and the hollow iron ball II (124), the loose state of the pull rope (9) can meet the zero-tension reopening requirement of the pull rope switch (8), the pull rope switch (8) is restarted, the belt conveyor is returned to operate, then the materials on the material receiving plate (18) are cleaned, and the blanking barrel (12) is returned to the initial state.
