[0033] Embodiment 1

[0034] Referring to Figures 1-8, a first embodiment of the present application provides a coal hopper coal pipe dredging device, comprising,

[0035] The main mechanism 100 comprises a raw coal hopper 101 and a connecting component 102 adapted and installed at the bottom end of the raw coal hopper 101.

[0036] The anti-blocking mechanism 200 comprises a rotating component 201 adapted and installed outside the connecting component 102, a power component 202 adapted and installed inside the rotating component 201, and an auxiliary component 203 adapted and installed inside the rotating component 201.

[0037] Specifically, the connecting component 102 comprises a first coal falling pipe 102a bolted to the bottom end of the raw coal hopper 101, and a tooth disc 102b fixedly connected to the bottom end of the first coal falling pipe 102a.

[0038] Further, the rotating component 201 comprises a transition pipe 201a rotatably connected to the outside of the first coal falling pipe 102a, and a second coal falling pipe 201b fixedly connected to the bottom end of the transition pipe 201a.

[0039] Still further, the rotating component 201 further comprises a baffle 201c fixedly connected to the inside of the transition pipe 201a, and a support assembly 201d adaptively installed on the outside of the transition pipe 201a.

[0040] Preferably, the support assembly 201d comprises a mounting cylinder 201d-1 fixedly connected to the outside of the transition pipe 201a, and a mounting disc 201d-2 fixedly connected to the inside of the mounting cylinder 201d-1.

[0041] It should be noted that the support assembly 201d further comprises a limiting column 201d-3 fixedly connected to the outside of the mounting disc 201d-2, and a first ball 201d-4 fixedly connected to the outside of the mounting disc 201d-2.

[0042] Among them, the first ball 201d-4 can slide in the spiral groove 203b and the ring groove 203c.

[0043] In addition, the power component 202 comprises a motor 202a adaptively installed on the outside of the mounting cylinder 201d-1, a square column 202b fixedly connected to the output shaft of the motor 202a, and a spring 202c arranged on the outside of the square column 202b.

[0044] Among them, the auxiliary component 203 comprises a cylinder 203a slidably connected to the outside of the square column 202b, a spiral groove 203b opened on the outside of the cylinder 203a, and a ring groove 203c opened on the outside of the cylinder 203a.

[0045] Among them, the two ends of the spring 202c are fixedly connected to the inside of the square column 202b and the cylinder 203a respectively.

[0046] Finally, the auxiliary component 203 further comprises a drill bit 203d fixedly connected to the outside of the cylinder 203a, and a transmission assembly 203e adaptively installed on the outside of the cylinder 203a.

[0047] When the coal falling pipe is blocked, the staff starts the motor 202a in the forward direction, the motor 202a drives the square column 202b to rotate, the square column 202b drives the cylinder 203a to rotate, because the first ball 201d-4 is arranged in the spiral groove 203b, under the guidance of the spiral groove 203b, the cylinder 203a rotates forward, and stretches the spring 202c, so that the drill bit 203d rotates and inserts into the blocked coal, and the coal is dredged.

[0048] When the cylinder 203a moves to the limit position, the cylinder 203a continues to rotate, which makes the first ball 201d-4 enter the ring groove 203c from the spiral groove 203b and slide in the ring groove 203c, as shown in FIG. 8.

[0049] In the case of continuous forward rotation of the motor 202a, the cylinder 203a will not reverse and reset, so the cylinder 203a will continue to rotate and will not retract.

[0050] In summary, starting the motor 202a in the forward direction can make the drill bit 203d rotate and insert into the blocked coal, and the drill bit 203d will not retract.

[0051] Embodiment 2

[0052] Referring to FIG. x-FIG. x, it is the second embodiment of the present application, which is different from the first embodiment: the working process of the transmission assembly 203e is provided.

[0053] Further, the transmission assembly 203e includes a bevel gear 203e-1 sleeved outside the cylinder 203a, a limiting groove 203e-2 opened in the bevel gear 203e-1, and a second ball 203e-3 fixedly connected in the bevel gear 203e-1.

[0054] Among them, the second ball 203e-3 can slide in the spiral groove 203b and the ring groove 203c.

[0055] During the process of the motor 202a rotating in the forward direction and the cylinder 203a rotating forward, the second ball 203e-3 also slides in the spiral groove 203b.

[0056] When the first ball 201d-4 enters the ring groove 203c, the second ball 203e-3 is still in the spiral groove 203b, as shown in FIG. 8.

[0057] At this time, the cylinder 203a continues to rotate, because the cylinder 203a cannot advance any more, so the second ball 203e-3 cannot continue to slide in the spiral groove 203b, so that when the cylinder 203a rotates, the side wall of the spiral groove 203b will extrude the second ball 203e-3, and drive the bevel gear 203e-1 to rotate synchronously.

[0058] Since the raw coal hopper 101 is connected with other components in the coal combustion system, the raw coal hopper 101 will not move, and the rotation of the bevel gear 203e-1 will drive the transition pipe 201a to rotate under the action of the gear plate 102b engaged therewith, and the rotation of the transition pipe 201a will drive the drill bit 203d to rotate and dredge in the coal, thereby completing the all-around dredging and making the dredging effect better.

[0059] In summary, by starting the motor 202a, the drill bit 203d can be inserted into the blocked coal and rotated after insertion, and the cooperation of the bevel gear 203e-1 and the gear plate 102b can realize the 360° rotation of the drill bit 203d, thereby making the dredging effect better.

[0060] Embodiment 3

[0061] Referring to FIGS. 1-8, the third embodiment of the present application is different from the second embodiment in that a reset process is provided.

[0062] After the dredging is completed, the motor 202a is reversed, and under the rebounding force of the spring 202c, the lower surface of the ring groove 203c is tightly attached to the first ball 201d-4. When the first ball 201d-4 is aligned with the spiral groove 203b, the first ball 201d-4 will enter the reversed spiral groove 203b, and continue to reverse, so that the cylinder 203a is reversed and retracted until it returns to the initial position.

[0063] In addition, during the reverse rotation of the cylinder 203a, the second ball 203e-3 moves along the spiral groove 203b. Since a large force is required to drive the second coal drop pipe 201b to rotate, the sliding friction between the second ball 203e-3 and the spiral groove 203b is not enough to cause the second coal drop pipe 201b to reverse during the movement of the second ball 203e-3 along the spiral groove 203b.
