[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-5 The utility model provides the following technical solutions: a device for preventing the coal drop pipe from being blocked in a coal bunker, comprising a coal drop pipe 1, an opening 2 being formed at the bottom of the coal drop pipe 1, a shell 3 being provided at the bottom of the coal drop pipe 1, two connecting rods 4 being passed through the bottom of the shell 3, and connecting sleeves 5 being connected to the outer walls of the two connecting rods 4;

[0025] The two ends of the two connecting rods 4 are respectively connected to a vibration plate 6 and a limit block 7. The outer wall of the connecting rod 4 is sleeved with a spring 8. The outer wall of the connecting sleeve 5 is connected to a connecting plate 9. The outer wall of the housing 3 is mounted with a motor 10. The output end of the motor 10 is connected to a rotating rod 11. One end of the rotating rod 11 is connected to an eccentric shaft 12.

[0026] It should be noted that the anti-blocking device is composed of a shell 3, a connecting rod 4, a connecting sleeve 5, a vibration plate 6, a limit block 7, a spring 8, a connecting plate 9, a motor 10, a rotating rod 11, an eccentric shaft 12, a mounting seat 15, a bidirectional screw 16, a threaded connecting block 17, an L-shaped plug 18, and a guide rod 19.

[0027] Preferably, the vibration plate 6 can form an elastic structure with the housing 3 through the connecting rod 4, the connecting sleeve 5, the limit block 7, and the spring 8. One end of the rotating rod 11 forms a rotating connection structure with the housing 3 through a bearing. The eccentric shaft 12 is located directly below the connecting plate 9.

[0028] It should be noted that the vibration plate 6 is adapted to the size of the opening 2 .

[0029] During specific use, the motor 10 drives the rotating rod 11 to rotate, so that the eccentric shaft 12 can continuously strike the connecting plate 9. Since the vibration plate 6 and the shell 3 are in an elastic structure, the vibration plate 6 can be driven to vibrate continuously as the eccentric shaft 12 strikes the connecting plate 9. Therefore, when the coal slides to the corner of the coal drop pipe 1, the continuous vibration of the vibration plate 6 can avoid coal blockage.

[0030] It should be noted that the motor 10 is connected to an external power supply and a control switch, and there are two springs 8 on the outer walls of the two connecting rods 4 respectively.

[0031] Preferably: the outer wall of the coal drop pipe 1 is connected to a fixing block 13, a limiting slot 14 is provided at the end of the fixing block 13, the end of the shell 3 is connected to a mounting seat 15, one end of the mounting seat 15 is penetrated by a bidirectional screw rod 16, the outer wall of the bidirectional screw rod 16 is threadedly connected to two threaded connection blocks 17, the tops of the two threaded connection blocks 17 are connected to an L-shaped plug block 18, a guide rod 19 is provided inside the mounting seat 15, the ends of the two threaded connection blocks 17 are sleeved on the outer wall of the guide rod 19, and the limiting slot 14 is adapted to the size of one end of the L-shaped plug block 18.

[0032] When in use, by rotating the bidirectional screw rod 16 counterclockwise, the two threaded connection blocks 17 threadedly connected to the outer wall can move toward each other along the guide rod 19. As the two threaded connection blocks 17 move toward each other, one end of the L-shaped plug block 18 on the top thereof will be disengaged from the inside of the limiting slot 14, thereby making it possible to conveniently remove the anti-blocking device.

[0033] On the contrary, when installing the anti-blocking device, first, embed the vibration plate 6 into the opening 2, and then rotate the bidirectional screw 16 clockwise so that the two threaded connection blocks 17 threadedly connected to the outer wall can move toward each other along the guide rod 19. As the two threaded connection blocks 17 move toward each other, one end of the L-shaped plug 18 on the top will be inserted into the limiting slot 14, thereby achieving fixation.

[0034] Working principle: First, the vibration plate 6 is embedded in the opening 2, and then the two-way screw rod 16 is rotated clockwise so that the two threaded connection blocks 17 connected to the outer wall can move toward each other along the guide rod 19. As the two threaded connection blocks 17 move toward each other, one end of the L-shaped plug block 18 on the top will be inserted into the limit slot 14, so that the anti-blocking device is installed at the bottom of the corner of the coal drop pipe 1. The motor 10 drives the rotating rod 11 to rotate, so that the eccentric shaft 12 can continuously knock the connecting plate 9. Since there is an elastic barrier between the vibration plate 6 and the shell 3, Structure, so as the eccentric shaft 12 strikes the connecting plate 9, it can drive the vibrating plate 6 to vibrate continuously, so that when the coal slides to the corner of the coal drop pipe 1, the continuous vibration of the vibrating plate 6 can avoid coal blockage, and finally, by rotating the bidirectional screw 16 counterclockwise, the two threaded connection blocks 17 threadedly connected on the outer wall can move toward each other along the guide rod 19. As the two threaded connection blocks 17 move toward each other, one end of the L-shaped plug 18 on the top will be disengaged from the inside of the limit slot 14, so that the anti-blocking device can be easily disassembled.

[0035] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
