[0033] Embodiment 1

[0034] Referring to FIGS. 1-4, a first embodiment of the present application provides a coal chute dredging anti-blocking device, which comprises a connecting unit 100, including a fixed top frame 101 and a swing frame 102 symmetrically installed at the bottom thereof.

[0035] The driving unit 200 comprises a motor 201 and a poking rod 202, the motor 201 is symmetrically fixed on the outer wall of the coal chute, one end of the poking rod 202 is connected with the output shaft of the motor 201, and the other end is connected with the swing frame 102.

[0036] The dredging unit 300 comprises a coal poking plate 301 and a top coal piece 302, the coal poking plate 301 is arranged between the swing frames 102 and connected with the poking rod 202, and the top coal piece 302 is movably installed at the bottom end of the swing frame 102.

[0037] The coal falling unit 400 comprises a coal falling pipe 401 and a shunt pipe 402 symmetrically fixed at the bottom thereof, the shunt pipe 402 is communicated with the coal falling pipe 401, and the fixed top frame 101 is fixed at the top of the coal falling pipe 401.

[0038] Among them, the fixed top frame 101 is fastened by bolts at the top inlet of the coal falling pipe 401, the swing frame 102 is symmetrically installed at the bottom thereof and close to the side wall of the coal falling pipe 401, so as to prevent too close to the middle of the coal falling pipe 401 and affect the coal falling efficiency.

[0039] The coal conveying belt 500 in FIG. 1 is used for conveying coal blocks.

[0040] Further, the swing frame 102 can swing left and right, alternately stirring in the two coal discharge pipes, dredging coal blocks on both sides at the same time, and improving the dredging efficiency.

[0041] Among them, the motor 201 adopts a servo motor with large power and torque, which can provide high-precision control and fast dynamic response capability.

[0042] Further, the motor 201 is externally connected with a control unit, which can control the motor 201 to rotate unidirectionally or alternately forward and reverse, so as to facilitate manual or intelligent control of the dredging work of the dredging unit 300.

[0043] The two ends of the coal poking plate 301 are fixed with the two sides of the swing frame 102, and the coal poking plate 301 is preferably provided with two plates, which can be flexibly folded to assist in turning over the coal blocks in the coal falling pipe 401, and improve the flowability of the coal blocks.

[0044] Further, the top coal member 302 is arranged at the bottom of the swing frame 102, can move up and down following the swing of the swing frame 102, and pushes the coal blocks in the two side diversion pipes 402 during the movement, so that the coal blocks are more quickly discharged from the diversion pipes 402.

[0045] Referring to FIG. 4, in the use process, the motor 201 is started, and the swing frame 102 swings left and right under the control of the poking rod 202. The poking rod 202 drives the coal poking plate 301 to turn over in the coal falling pipe 401. When the angle between the coal poking plates 301 is reduced, large coal blocks are crushed. When the coal poking plate 301 swings to the left side, most of the coal blocks can be discharged from the right side diversion pipe 402, and vice versa.

[0083] The top fixed frame 101a can be rectangular or annular, and is made according to the shape of the coal falling pipe 401. The cross beam 101b extends slightly to the middle of the coal falling pipe 401, and the bearing plate 101c is inserted downward into the coal falling pipe 401, so as to facilitate the swing frame 102 to work in the central area of the coal falling pipe 401.

[0084] The toggle lever 202 comprises a toggle plate 202a, and connecting shafts 202b and a pushing slide column 202c fixed at both side ends of the toggle plate 202a.

[0085] The toggle lever 202 is a "Z" bending lever as a whole. When the motor 201 drives the connecting shafts 202b to rotate, the toggle plate 202a drives the pushing slide column 202c to move in the slide hole 102a-2. At this time, the overall height of the pushing slide column 202c depends on the rotating angle of the motor 201, that is, the inner-embedded slide pushing piece 301c and the movable lever 301b can keep the same height with the pushing slide column 202c through the rotating sleeve ring 301c-2a.

[0086] The rest of the structure is the same as that of the embodiment 2.
