[0014] The present invention also discloses a method for using an anti-clogging pneumatic ash conveying device, which uses the anti-clogging pneumatic ash conveying device and comprises the following steps:

[0015] S1. When the material falls into the barrel, the air compressor is started, and the air compressor delivers pressurized air to the inside of the air guide pipe, and then the powder is delivered to the designated position through the delivery pipe. In this process, the two driving motors are started, and the output end of one driving motor drives one winding roller to reel in one traction rope, and the output end of the other driving motor drives another winding roller to release another traction rope, thereby pulling the sliding ring to move laterally inside the delivery pipe, and then the agglomerated material inside the delivery pipe is suspended by the conical scraper block, thereby preventing the agglomerated material from accumulating inside the delivery pipe, thereby improving the patency of the delivery pipe;

[0016] When the sliding ring moves horizontally to the maximum position, the two output ends of the driving motor rotate in opposite directions, thereby driving the sliding ring to reset, and reciprocating in this way, thereby achieving the effect of clearing the inside of the conveying pipe;

[0017] S2. When the sliding ring moves laterally, since the second spur rack is fixed, the first spur gear is driven to drive the rotating rod to rotate in a circle, thereby driving the two crushing rollers to rotate in a circle through the connecting block, so as to crush the material inside the conveying pipe. At the same time, the conical scraper block can guide the agglomerated material to the inner side of the sliding ring through the inner slope during the scraping process inside the conveying pipe, so that the two crushing rollers can crush it, thereby avoiding the internal blockage of the conveying pipe during the conveying process, thereby ensuring the normal operation of the conveying pipe, and there is no need to stop the machine to dredge the inside of the conveying pipe, thereby improving the overall operation efficiency of the device;

[0018] S3, when the connecting block rotates in a circle, it drives the auxiliary wheel to rotate. When the auxiliary wheel contacts the arched ramp, when the auxiliary wheel moves along the lowest point of the arched ramp to the highest point, it will push the sliding seat to drive the two crushing rollers to move horizontally. When the auxiliary wheel gradually moves from the highest point of the arched ramp to the lowest point, the connecting spring will push the crushing roller to reset, and the reciprocating movement will expand the range of crushing the agglomerated materials, thereby reducing the accumulation of agglomerated materials, thereby further improving the efficiency of ash conveying;

[0019] When the sliding seat drives the two crushing rollers to move in the direction of the third spur rack, it drives the second spur gear to move synchronously, so that the second spur gear is driven to rotate by the third spur rack, and then drives the other second spur gear to rotate synchronously, so that the two crushing rollers can rotate to actively crush, thereby further improving the effect of crushing the agglomerated materials;

[0020] S4. When the sliding ring moves toward the discharge port of the conveying pipe, it drives the power star ring to move synchronously. When the first spur rack contacts the third spur gear, the third spur gear will be driven to drive the rotating shaft to rotate, and then the swing rod will drive the stripper plate and the connecting plate to swing toward the inside of the conveying pipe. In this process, the stripper plate is resisted by the inner wall of the conveying pipe, thereby pushing the sliding rod to slide relative to the connecting plate, so that the stripper plate is always in contact with the inner wall of the conveying pipe under the action of the auxiliary spring. In this way, the stripper plate gradually swings, and the agglomerated materials accumulated at the discharge port of the conveying pipe can be pushed into the inside of the conveying pipe, so that the conical scraper block can shovel it away, thereby avoiding the blockage of the discharge port of the conveying pipe, thereby further improving the overall dredging effect of the device, so that the device can carry out stable ash conveying.

[0021] The working principle and beneficial effects of the present invention are:

[0022] 1. By setting a breaker, when the sliding ring moves horizontally, the second spur rack is fixed, thereby driving the first spur gear to drive the rotating rod to rotate in a circle, thereby driving the two crushing rollers to rotate in a circle through the connecting block, so as to crush the materials inside the conveying pipe. At the same time, the conical scraper block can guide the agglomerated materials to the inside of the sliding ring through the inner slope during the scraping process inside the conveying pipe, so that the two crushing rollers can crush them, thereby avoiding the internal blockage of the conveying pipe during the conveying process, thereby ensuring the normal operation of the conveying pipe, and there is no need to stop the machine to dredge the inside of the conveying pipe, thereby improving the overall operation efficiency of the device;

[0023] 2. By setting up a cleaning mechanism, two driving motors are started, and the output end of one driving motor drives a winding roller to wind up a traction rope, and the output end of the other driving motor drives another winding roller to release another traction rope, thereby pulling the sliding ring to move laterally inside the conveying pipe, and then the agglomerated materials inside the conveying pipe are suspended by the conical scraper block, thereby preventing the agglomerated materials from accumulating inside the conveying pipe, thereby improving the patency of the conveying pipe;

[0024] 3. By setting up the coordination of parts such as the arched ramp, when the connecting block rotates in a circle, it drives the auxiliary wheel to rotate. When the auxiliary wheel contacts the arched ramp, it moves along the lowest point of the arched ramp to the highest point, which pushes the sliding seat to drive the two crushing rollers to move horizontally. When the auxiliary wheel gradually moves from the highest point of the arched ramp to the lowest point, the connecting spring pushes the crushing roller to reset, and the reciprocating movement is carried out, thereby expanding the range of crushing the agglomerated materials, thereby reducing the accumulation of agglomerated materials, and further improving the efficiency of ash conveying;

[0025] When the sliding seat drives the two crushing rollers to move in the direction of the third spur rack, it drives the second spur gear to move synchronously, so that the second spur gear is driven to rotate by the third spur rack, and then drives another second spur gear to rotate synchronously, so that the two crushing rollers can rotate to actively crush, thereby further improving the effect of crushing the agglomerated materials;

[0026] 4. By setting a material-pickup piece, when the sliding ring moves toward the discharge port of the conveying pipe, it drives the power star ring to move synchronously. When the first spur rack contacts the third spur gear, it drives the third spur gear to drive the rotating shaft to rotate, and then drives the material-pickup plate and the connecting plate to swing toward the inside of the conveying pipe through the swing rod. In this process, the material-pickup plate is resisted by the inner wall of the conveying pipe, thereby pushing the sliding rod to slide relative to the connecting plate, so that the material-pickup plate is always attached to the inner wall of the conveying pipe under the action of the auxiliary spring. In this way, the material-pickup plate gradually swings, and the agglomerated materials accumulated at the discharge port of the conveying pipe can be pushed into the conveying pipe, so that the conical scraper block can shovel it away, thereby avoiding blockage of the discharge port of the conveying pipe, thereby further improving the overall dredging effect of the device, so that the device can carry out stable ash conveying.

When the auxiliary wheel 31 contacts the arched ramp 32, the auxiliary wheel 31 moves along the lowest point of the arched ramp 32 to the highest point, which pushes the sliding seat 28 to drive the two crushing rollers 13 to move horizontally. When the auxiliary wheel 31 gradually moves from the highest point of the arched ramp 32 to the lowest point, the connecting spring 29 pushes the crushing roller 13 to reset, and the reciprocating movement is carried out, thereby expanding the range of crushing the agglomerated materials, thereby reducing the accumulation of agglomerated materials, and further improving the efficiency of ash conveying;

[0059] When the sliding seat 28 drives the two crushing rollers 13 to move toward the third spur rack 27, it drives the second spur gear 26 to move synchronously, so that the second spur gear 26 is driven to rotate by the third spur rack 27, and then drives the other second spur gear 26 to rotate synchronously, so that the two crushing rollers 13 can rotate to actively crush, thereby further improving the effect of crushing the agglomerated materials;

[0060] S4. When the sliding ring 11 moves toward the discharge port of the conveying pipe 2, it drives the power star ring 19 to move synchronously. When the first spur rack 20 contacts the third spur gear 35, it will drive the third spur gear 35 to drive the rotating shaft 36 to rotate, and then drive the material stripping plate 15 and the connecting plate 16 to swing toward the inside of the conveying pipe 2 through the swing rod 14.

9. A method for using an anti-clogging pneumatic ash conveying device, characterized in that: The anti-clogging pneumatic ash conveying device according to claim 8 comprises the following steps: S1. When the material falls into the barrel (1), the air compressor (4) is started, and the air compressor (4) delivers pressurized air to the inside of the air guide tube (3), and then the powder is delivered to the designated position through the conveying tube (2). In this process, the two driving motors (6) are started, and the output end of one driving motor (6) drives a winding roller (7) to wind up a traction rope (8), and the output end of the other driving motor (6) drives another winding roller (7) to release another traction rope (8), thereby pulling the sliding ring (11) to move laterally inside the conveying tube (2), and then the agglomerated material inside the conveying tube (2) is suspended by the conical scraper block (12), thereby preventing the agglomerated material from accumulating inside the conveying tube (2), thereby improving the patency of the conveying tube (2); When the sliding ring (11) moves horizontally to the maximum position, the output ends of the two driving motors (6) rotate in opposite directions, thereby driving the sliding ring (11) to reset, and in this way the sliding ring (11) reciprocates, thereby achieving the effect of clearing the inside of the conveying pipe (2); S2. When the sliding ring (11) moves laterally, since the second spur rack (22) is fixed, the first spur gear (23) is driven to drive the rotating rod (24) to rotate in a circle, thereby driving the two crushing rollers (13) to rotate in a circle through the connecting block (25), thereby crushing the material inside the conveying pipe (2). At the same time, the conical scraper block (12) can guide the agglomerated material to the inside of the sliding ring (11) through the inner slope during the scraping process inside the conveying pipe (2), so that the two crushing rollers (13) can crush it, thereby avoiding the conveying pipe (2) from being blocked during the conveying process, thereby ensuring the normal operation of the conveying pipe (2) without stopping the machine to clear the inside of the conveying pipe (2), thereby improving the overall operation efficiency of the device; S3, when the connecting block (25) rotates in a circle, the auxiliary wheel (31) is driven to rotate. When the auxiliary wheel (31) contacts the arched ramp (32), the auxiliary wheel (31) moves along the lowest point of the arched ramp (32) to the highest point, and pushes the sliding seat (28) to drive the two crushing rollers (13) to move laterally. When the auxiliary wheel (31) gradually moves from the highest point of the arched ramp (32) to the lowest point, the connecting spring (29) pushes the crushing roller (13) to reset, and the two crushing rollers (13) are reciprocated, thereby expanding the range of crushing the agglomerated materials, thereby reducing the accumulation of agglomerated materials, and further improving the efficiency of ash conveying; When the sliding seat (28) drives the two crushing rollers (13) to move in the direction of the third spur rack (27), it drives the second spur gear (26) to move synchronously, thereby driving the second spur gear (26) to rotate by the third spur rack (27), and then driving the other second spur gear (26) to rotate synchronously, so that the two crushing rollers (13) can rotate by themselves to actively crush, thereby further improving the effect of crushing agglomerated materials; S4. When the sliding ring (11) moves toward the discharge port of the conveying pipe (2), it drives the power star ring (19) to move synchronously. When the first spur rack (20) contacts the third spur gear (35), the third spur gear (35) drives the rotating shaft (36) to rotate, and then drives the material-pickup plate (15) and the connecting plate (16) to swing toward the inside of the conveying pipe (2) through the swing rod (14). In this process, the material-pickup plate (15) is resisted by the inner wall of the conveying pipe (2), thereby pushing the sliding ring (11) to rotate. The movable rod (17) slides relative to the connecting plate (16), so that the material-discharging plate (15) is always in contact with the inner wall of the conveying pipe (2) under the action of the auxiliary spring (38). The material-discharging plate (15) gradually swings, and the agglomerated materials accumulated at the discharge port of the conveying pipe (2) can be pushed into the inside of the conveying pipe (2), so that the conical scraper block (12) can shovel them away, thereby avoiding the discharge port of the conveying pipe (2) from being blocked, thereby further improving the overall dredging effect of the device, so that the device can carry out stable ash conveying.
