[0032] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0033] Example 1

[0034] Reference Figures 1 to 8 , which is the first embodiment of the present invention, provides a device for dredging the coal hopper drop pipe, comprising:

[0035] The main body 100 includes a raw coal hopper 101 and a connecting component 102 adapted to be installed at the bottom end of the raw coal hopper 101;

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

[0037] Specifically, the connecting component 102 includes a first coal dropping pipe 102a bolted to the bottom end of the raw coal hopper 101, and a gear plate 102b fixedly connected to the bottom end of the first coal dropping pipe 102a.

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

[0039] Furthermore, the rotating component 201 further includes a baffle 201c fixedly connected to the interior of the transition pipe 201a, and a support assembly 201d adapted to be installed on the outside of the transition pipe 201a.

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

[0041] It should be noted that the support assembly 201d further includes a limiting post 201d-3 fixedly connected to the outside of the mounting plate 201d-2, and a first round bead 201d-4 fixedly connected to the outside of the mounting plate 201d-2;

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

[0043] In addition, the power component 202 includes a motor 202a adapted to be mounted 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] The auxiliary component 203 includes a cylinder 203a slidably connected to the outside of the square column 202b, a spiral groove 203b provided on the outside of the cylinder 203a, and an annular groove 203c provided on the outside of the cylinder 203a.

[0045] 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 includes a drill bit 203d fixedly connected to the outside of the cylinder 203a, and a transmission assembly 203e adapted to be installed on the outside of the cylinder 203a.

[0047] When the coal drop pipe is blocked, the staff starts the motor 202a to rotate forward, and the motor 202a drives the square column 202b to rotate, and the square column 202b drives the cylinder 203a to rotate. Since the first ball 201d-4 is set inside 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 to clear the coal.

[0048] When the cylinder 203a moves to the limit position, the cylinder 203a continues to rotate, causing the first ball 201d-4 to enter the annular groove 203c from the spiral groove 203b and slide inside the annular groove 203c. Figure 8 shown.

[0049] When the motor 202a continues to rotate forward, the cylinder 203a will not reverse and reset, so the cylinder 203a will continue to rotate forward and will not retract.

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

[0051] Example 2

[0052] Reference Figures 1 to 8 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that it provides a working process of the transmission component 203e.

[0053] Furthermore, the transmission assembly 203e includes a bevel gear 203e-1 sleeved on the outside of the cylinder 203a, a limiting groove 203e-2 provided inside the bevel gear 203e-1, and a second ball 203e-3 fixedly connected to the inside of the bevel gear 203e-1;

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

[0055] When the motor 202a rotates forward and the cylinder 203a rotates forward, the second ball 203e-3 will also slide inside the spiral groove 203b.

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

[0057] At this time, the cylinder 203a continues to rotate. Since the cylinder 203a can no longer move forward, the second ball 203e-3 cannot continue to slide in the spiral groove 203b. As a result, when the cylinder 203a rotates, the side wall of the spiral groove 203b squeezes the second ball 203e-3 and drives the bevel gear 203e-1 to rotate synchronously.

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

[0059] In summary, by starting the motor 202a, the drill bit 203d can be rotated and inserted into the blocked coal. After insertion, the drill bit 203d can be rotated 360 degrees with the cooperation of the bevel gear 203e-1 and the toothed disc 102b, thereby achieving a better dredging effect.

[0060] Example 3

[0061] Reference Figures 1 to 8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that a reset process is provided.

[0062] After the dredging is completed, the motor 202a is reversed. Under the action of the rebound force of the spring 202c, the lower surface of the annular groove 203c will be close to the first round ball 201d-4. When the first round ball 201d-4 is aligned with the spiral groove 203b, the first round ball 201d-4 will enter the reversed spiral groove 203b. Continuing to reverse, the cylinder 203a can be reversed and retracted until it returns to its initial position.

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

[0064] It is important to note that the construction and arrangement of the present application, as illustrated in various exemplary embodiments, are illustrative only. Although only a few embodiments are described in detail in this disclosure, those reading this disclosure will readily appreciate that numerous modifications are possible (e.g., variations in the size, dimensions, structure, shape, and proportions of various components, as well as parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, orientation, etc.) without materially departing from the novel teachings and advantages of the subject matter described herein.
