When using screw unloading machine to unload powder material, the powder material is usually transported upward by screw auger. However, due to the small size of powder particles, part of the powder may move to the pipe wall under the pushing action of the screw auger, some of which may fall from the gap between the screw auger and the pipe wall, and may accumulate at the bottom of the conveying pipe. These accumulated powder will occupy the space at the bottom of the pipe, not only need to be transported by the screw auger again, but also hinder the new powder in the cabin from entering the pipe, resulting in the decrease of the overall conveying efficiency.

[0011] The material taking assembly is rotationally arranged at the inner wall of the material taking assembly and the outer wall of the feeding pipe, and is used for pushing the powder material in the cabin into the conveying assembly.

[0012] When it is necessary to unload the cabin, the material taking assembly is inserted into the powder material, then the material is pushed into the conveying assembly by the material taking assembly, and then the material is conveyed upward by the conveying assembly to unload the material in the cabin.

[0016] The sliding member comprises a sliding frame slidingly connected to the inner wall of the rotating rod, and the bottom of the sliding frame is fixedly connected with a connecting frame.

[0017] During the conveying of the powder, the powder is blocked by the material blocking assembly, then the conveyed powder is extruded by the extrusion assembly to make the powder agglomerate and reduce the flowability, so that the powder falling from the gap between the spiral auger and the inner wall of the feeding pipe is reduced when the powder is discharged.

[0018] Preferably, the anti-blocking assembly comprises:

[0019] The pushing assembly is fixedly arranged at the inner wall of the air pressure cylinder, and is used for pushing the discharged powder to flow quickly.

[0022] Wherein, when the upward conveying material is discharged, the flow speed of the powder material is accelerated by the pushing assembly, effectively preventing the powder from agglomerating, reducing the flowability of the powder, and making it difficult to flow in the discharge chute, which may cause the powder to accumulate in the discharge chute position, affecting the discharge of the powder, and the fallen powder is pushed by the air jet assembly to move towards the direction of the rotating rod, so that it is conveyed again, the scattered material is recovered, and the conveying efficiency is improved.

[0023] Preferably, the conveying assembly comprises a belt pulley set arranged at the top of the feeding pipe, the inner wall of the belt pulley set is fixedly connected with the outer wall of the rotating rod, and the outer wall of the spiral auger is fixedly connected with a motor one;

[0024] The top output end of the motor one is fixedly connected with the bottom of the belt pulley set, and the inner wall of the feeding pipe is provided with a discharge chute.

[0025] Preferably, the material taking assembly comprises a gear ring rotatably connected to the outer wall of the feeding pipe, the bottom of the gear ring is fixedly connected with a material taking head, and the inner wall of the feeding pipe is rotatably connected with a gear rod;

[0026] The top of the feeding pipe is fixedly connected with a motor two, the bottom output end of the motor two is fixedly connected with the top of the gear rod, and the outer wall of the gear rod is meshingly connected with the outer wall of the gear ring;

[0027] Wherein, when the ship cabin needs to be unloaded, the motor two is started, the gear ring is rotated by the gear rod, the material taking head is rotated, the powder material is pushed into the feeding pipe, and then the motor one is started, the rotating rod and the spiral auger are rotated by the belt pulley set, and the powder material is conveyed upward.

[0028] Preferably, the material blocking assembly comprises a spring ring slidably connected to the inner wall of the air pressure cylinder, and the top of the spring ring is slidably connected with the bottom of the concave-convex ring;

[0029] Wherein, when the spiral auger conveys the powder material, the material will rotate around the center of the rotating rod, the powder material is affected by the centrifugal force, part of the material will move towards the inner wall of the feeding pipe, and the moving material will be blocked by the spiral baffle, at the same time, when the rotating rod rotates, the concave-convex ring will also rotate, when the convex position of the concave-convex ring contacts with the spring ring, the spring ring will be pressed to descend, and the spring ring will accumulate the elastic force.

[0030] Preferably, the extrusion assembly comprises an F-shaped rod fixedly connected to the top of the spring ring, the inner wall of the F-shaped rod is rotatably connected with the outer wall of the sliding frame, and the inner wall of the rotating rod is slidably connected with two extrusion blocks;

[0031] The side wall of each of the two extrusion blocks is rotatably connected with a connecting rod, the inner wall of each of the two connecting rods is rotatably connected with the bottom of the connecting frame, and the outer wall of the rotating rod is fixedly connected with a blocking block;

[0032] Wherein, the spring ring drops, which drives the F-shaped rod to drop, the F-shaped rod pushes the sliding frame to drop, the connecting frame pushes the connecting rod to rotate, the connecting rod pushes the extrusion block to move towards the spiral baffle, with the continuous rotation of the concave-convex ring, when the concave-convex ring is in contact with the spring ring, the spring ring is released by the elastic force, and the spring ring is reset, the sliding frame is lifted, the extrusion block is reset, and the concave-convex ring extrudes the extrusion block again. The extrusion block reciprocates, and when the powder moves to the position of the baffle, part of the powder is blocked by the baffle, and the extrusion block moves towards the spiral baffle, which extrudes the powder, blocks the powder through the spiral cover, and avoids the overflow of the powder from the top of the spiral baffle. Then, the powder is continuously conveyed, and when the powder moves to the position of the discharge slot of the feeding pipe, the powder falls into the discharge slot, and the material moves along the discharge slot towards the spiral ship unloader, the powder material is discharged through the spiral ship unloader, the powder is blocked by the spiral baffle, the powder is concentrated, the falling powder in the conveying process is reduced, and then the extrusion block extrudes the powder to make the powder agglomerate, so that the powder bulk density is reduced. When the powder is discharged to the position of the discharge slot, the falling powder is reduced, which effectively prevents the falling of a large amount of powder from the gap between the spiral auger and the inner wall of the feeding pipe, and the powder is accumulated at the bottom of the feeding pipe, which affects the conveying efficiency of the powder.

[0033] Preferably, the pushing assembly comprises a jet pipe connected through the inner wall of the air cylinder, and a plug rod is slidably connected to the inner wall of the jet pipe;

[0034] The top of the plug rod is fixedly connected to the bottom of the spring ring, and a plurality of air supplement pipes are connected through the inner walls of the air cylinder and the feeding pipe;

[0035] When the spring ring drops and passes through the air supplement pipe, the bottom of the spring ring is in a sealed state, and the spring ring is extruded by the gas in the air cylinder. At this time, the extruded gas is blocked by the plug rod. As the spring ring drops, the plug rod drops, and with the continuous movement of the plug rod, the plug rod is separated from the jet pipe, and the blocking of the gas is cancelled. At this time, the high-pressure gas enters the jet pipe, and the powder in the discharge slot is pushed out by the jet pipe, which effectively prevents the powder from agglomerating and reducing the flowability of the powder, and the powder may be accumulated in the discharge slot, which affects the discharge of the powder.

[0036] Preferably, the jet assembly comprises a spring air blocking block slidably connected to the inner wall of the arc-shaped block, a plurality of air inlet holes are formed in the inner walls of the arc-shaped block and the feeding pipe, and the top of the arc-shaped plate is fixedly connected to the bottom of the spring ring;

[0037] The arc-shaped block and the inner wall of the feeding pipe are both provided with exhaust holes, and the inner wall of the feeding pipe is fixedly connected with an air pressure ring, and the inner wall of the air pressure ring is provided with a plurality of jet holes one;

[0039] When the spring ring descends, it drives the arc-shaped plate to descend, and when the arc-shaped plate covers the air inlet hole, it will extrude the gas in the arc-shaped block. The extruded gas will be blocked by the spring air blocking block, so the gas pressure will increase until the convex position of the arc-shaped plate contacts the spring air blocking block during the descending process, which will push the spring air blocking block to descend and accumulate the elastic force. After the spring air blocking block descends, it will cancel the blocking of the gas, so that the high-pressure gas enters the exhaust hole and enters the air pressure ring through the exhaust hole. When the rotating rod rotates, it will drive the connecting rod to rotate, and the connecting rod will drive the blocking ring to rotate. When the blocking ring rotates, the jet holes two in the blocking ring are connected with the jet holes one in the air pressure ring, and the high-pressure gas will be sprayed out through the jet holes one and the jet holes two in the direction of the rotating rod. When the falling powder contacts the gas, it will be affected by the gas thrust and move towards the rotating rod, so that the powder falls again on the surface of the screw auger, so that the screw auger can transport the powder again, recycle the scattered material and improve the conveying efficiency.

[0040] The present application has the following beneficial effects:

[0041] (1) When the present application is used, the device is installed with the screw unloader together. When it is necessary to unload the powder in the cabin, the powder material in the cabin is pushed into the feeding pipe by the material taking assembly, and then the rotating rod and the screw auger are rotated by the conveying assembly to convey the powder upward. At the same time, the concave-convex ring is rotated by the rotating rod, the spring ring is extruded to descend, the extrusion block is extruded by the reciprocating assembly, the powder is agglomerated, the powder bulk density is reduced, and the powder flowability is reduced. When the powder is discharged to the discharge slot, the powder falling from the gap between the screw auger and the inner wall of the feeding pipe is reduced, the powder accumulated at the bottom of the feeding pipe is effectively prevented, and the conveying efficiency of the powder is affected.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0059] Embodiment one, please refer to Figures 1-5The application discloses a continuous quantitative unloading device for bulk cargo at a wharf, which comprises a feeding pipe 111, a rotating rod 112 rotatably connected to the inner wall of the feeding pipe 111, and a spiral auger 113 arranged on the inner wall of the feeding pipe 111 and fixedly connected to the outer wall of the rotating rod 112.

[0060] The unloading mechanism 1 is provided with the conveying assembly 11 rotatably arranged on the inner wall of the unloading mechanism 1 and the material taking assembly 12 arranged on the outer wall of the unloading mechanism 1, and the conveying assembly 11 is used for conveying powder materials.

[0061] The blocking mechanism 2 is arranged on the inner wall of the unloading mechanism 1 and used for blocking the powder during the conveying of the conveying assembly 11.

[0062] The anti-blocking assembly 3 is arranged on the inner wall of the unloading mechanism 1 and used for pushing the powder to flow rapidly.

[0063] The spiral baffle 211 is fixedly connected to the outer wall of the spiral auger 113, the spiral cover plate 212 is fixedly connected to the top of the spiral baffle 211, the concave-convex ring 213 is fixedly connected to the outer wall of the rotating rod 112, and the air pressure cylinder 214 is fixedly connected to the inner wall of the feeding pipe 111.

[0064] When it is needed to unload the ship cabin, the powder materials are pushed into the conveying assembly 11 by the material taking assembly 12, and then the powder materials are conveyed upwards by the conveying assembly 11, during the conveying process, the powder is blocked by the blocking mechanism 2, so that the powder is effectively prevented from falling from the gap between the spiral auger 113 and the inner wall of the feeding pipe 111, the powder is accumulated at the bottom of the feeding pipe 111, and the conveying efficiency of the powder is affected, finally, the materials flow rapidly by the anti-blocking assembly 3.

[0065] The unloading mechanism 1 comprises:

[0066] The conveying assembly 11 is rotatably arranged on the outer wall of the feeding pipe 111 and used for conveying the powder materials upwards.

[0067] The material taking assembly 12 is rotatably arranged on the outer wall of the feeding pipe 111 and used for pushing the powder materials in the ship cabin into the conveying assembly 11.

[0068] When it is needed to unload the ship cabin, the material taking assembly 12 is inserted into the powder materials, then the materials are pushed into the conveying assembly 11 by the material taking assembly 12, and finally the materials are conveyed upwards by the conveying assembly 11 to unload the ship cabin.

[0069] The blocking mechanism 2 comprises:

[0070] The material blocking assembly 21 is fixedly arranged at the outer wall of the spiral auger 113 and used for blocking the powder from falling off;

[0071] The extruding assembly 22 is slidably arranged at the inner wall of the rotating rod 112 by a sliding piece and used for extruding the powder;

[0072] The sliding piece comprises a sliding frame 221 slidably connected at the inner wall of the rotating rod 112, and the bottom of the sliding frame 221 is fixedly connected with a connecting frame 223.

[0073] During the powder conveying process, the powder is blocked by the material blocking assembly 21, then the conveyed powder is extruded by the extruding assembly 22 to make the powder agglomerate and reduce the flowability, so that the powder falling off from the gap between the spiral auger 113 and the inner wall of the feeding pipe 111 is reduced when the powder is discharged.

[0074] The anti-blocking assembly 3 comprises:

[0075] The pushing assembly 31 is fixedly arranged at the inner wall of the air pressure cylinder 214 and used for pushing the discharged powder to flow quickly;

[0077] The fixing piece comprises an arc-shaped block 321 fixedly connected at the bottom of the air pressure cylinder 214, and an arc-shaped plate 322 slidably connected at the inner wall of the arc-shaped block 321.

[0078] When the upwardly conveyed material is discharged, the pushing assembly 31 is used to accelerate the flow speed of the powder material, so that the powder flowability is effectively prevented from being reduced after the powder agglomerates, the powder is difficult to flow in the discharge slot, and the powder may be gathered at the discharge slot position to affect the discharge of the powder. The air jet assembly 32 is used to push the falling powder to move towards the direction of the rotating rod 112, so that the powder is conveyed again, the scattered material is recovered, and the conveying efficiency is improved.

[0079] In the second embodiment, please refer to Figures 1-10 On the basis of the first embodiment, the conveying assembly 11 comprises a belt pulley set 114 arranged at the top of the feeding pipe 111, the belt pulley set 114 is fixedly connected with the outer wall of the rotating rod 112 at the inner wall thereof, and the outer wall of the spiral auger 113 is fixedly connected with a motor one 115.

[0080] The top output end of the motor one 115 is fixedly connected with the bottom of the belt pulley set 114, and the inner wall of the feeding pipe 111 is provided with a discharge slot.

[0081] The taking-out assembly 12 comprises a gear ring 121 rotatably connected at the outer wall of the feeding pipe 111, the bottom of the gear ring 121 is fixedly connected with a taking-out head 122, and the inner wall of the feeding pipe 111 is rotatably connected with a gear rod 124;

[0082] The top of the feeding pipe 111 is fixedly connected with a motor two 123, the bottom output end of the motor two 123 is fixedly connected with the top of the gear rod 124, and the outer wall of the gear rod 124 is meshedly connected with the outer wall of the gear ring 121;

[0083] When it is needed to unload the cabin, the motor two 123 is started, the gear ring 121 is rotated through the gear rod 124, the taking-out head 122 is rotated, the powder material is pushed into the feeding pipe 111, and then the motor one 115 is started, the rotating rod 112 and the spiral auger 113 are rotated through the belt pulley set 114, and the powder material is conveyed upwards.

[0084] The material blocking assembly 21 comprises a spring ring 215 slidably connected at the inner wall of the air pressure cylinder 214, and the top of the spring ring 215 is slidably connected with the bottom of the concave-convex ring 213;

[0085] When the spiral auger 113 conveys the powder material, the material is rotated around the center of the rotating rod 112, the powder material is affected by the centrifugal force, part of the material moves towards the inner wall of the feeding pipe 111, the moved material is blocked by the spiral baffle 211, and meanwhile, the concave-convex ring 213 is rotated when the rotating rod 112 rotates, the convex position of the concave-convex ring 213 is in contact with the spring ring 215, the spring ring 215 is pressed to descend, and the spring ring 215 accumulates the elastic force.

[0086] The pressing assembly 22 comprises an F-shaped rod 222 fixedly connected at the top of the spring ring 215, the inner wall of the F-shaped rod 222 is rotatably connected with the outer wall of a sliding frame 221, and the inner wall of the rotating rod 112 is slidably connected with two pressing blocks 225;

[0087] The side wall of each of the two pressing blocks 225 is rotatably connected with a connecting rod 224, the inner wall of each of the two connecting rods 224 is rotatably connected with the bottom of a connecting frame 223, and the outer wall of the rotating rod 112 is fixedly connected with a stop block 226;

[0088] The descent of spring ring 215 causes F-shaped rod 222 to descend, which in turn pushes sliding frame 221 to descend, causing connecting frame 223 to descend. Connecting frame 223 then pushes connecting rod 224 to rotate, causing connecting rod 224 to push extrusion block 225 towards spiral baffle 211. As the concave-convex ring 213 continues to rotate, when the concave position of the concave-convex ring 213 contacts spring ring 215, the spring ring 215's rebound force is released, causing it to return to its original position. This allows sliding frame 221 to rise, thus extruding the extrusion block 225. Block 225 returns to its original position until the concave-convex ring 213 presses the extrusion block 225 down again. This process is repeated, allowing the extrusion block 225 to extend and return to its original position. When the powder moves to the position of the stop block 226, some of the powder will be blocked by the stop block 226. As the extrusion block 225 moves towards the spiral baffle 211, it will compress the powder. The spiral cover plate 212 blocks the powder, preventing it from overflowing from the top of the spiral baffle 211. After that, the powder continues to be conveyed. When the powder moves to the discharge chute position of the feeding pipe 111, as... Figure 5 As shown in the state of G, the powder will fall into the discharge chute, allowing the material to move along the discharge chute towards the screw unloader. The screw unloader will then discharge the powder material. The screw baffle 211 will block the powder, causing it to concentrate and reducing the amount of powder falling during the conveying process. Then, the extrusion block 225 will compress the powder, causing it to agglomerate and reducing its looseness and fluidity. When the powder is discharged towards the discharge chute, the amount of powder falling from this point will be reduced, effectively preventing a large amount of powder from falling through the gap between the screw auger 113 and the inner wall of the feeding pipe 111, which would cause powder to accumulate at the bottom of the feeding pipe 111 and affect the powder conveying efficiency.

[0089] The pushing component 31 includes a jet pipe 311 that is connected through the inner wall of the air cylinder 214, and a blocking rod 312 is slidably connected to the inner wall of the jet pipe 311.

[0090] The top of the blocking rod 312 is fixedly connected to the bottom of the spring ring 215, and several air supply pipes 313 are connected through the inner wall of the air cylinder 214 and the feeding pipe 111.

[0091] When the spring ring 215 descends, after it passes the air supply pipe 313, the bottom of the spring ring 215 is sealed. As the spring ring 215 descends, it compresses the gas inside the air cylinder 214. The compressed gas is blocked by the blocking rod 312. As the spring ring 215 descends, it drives the blocking rod 312 to descend as well. With the continuous movement of the blocking rod 312, it separates from the jet pipe 311, removing the obstruction to the gas. At this time, the high-pressure gas enters the jet pipe 311 and is sprayed onto the powder in the discharge trough, pushing the powder to move. This effectively prevents the powder from agglomerating, which would reduce its fluidity and make it difficult to flow in the discharge trough, potentially causing the powder to accumulate at the discharge trough position and affecting the discharge of the powder.

[0092] The jet assembly 32 includes a spring-loaded air block 324 that is slidably connected to the inner wall of the arc-shaped block 321. Both the arc-shaped block 321 and the inner wall of the feeding pipe 111 are provided with a number of air inlets 323. The top of the arc-shaped plate 322 is fixedly connected to the bottom of the spring ring 215.

[0093] Both the arc-shaped block 321 and the inner wall of the feeding pipe 111 are provided with exhaust holes 325. An air pressure ring 326 is fixedly connected to the inner wall of the feeding pipe 111. Several air jet holes are provided on the inner wall of the air pressure ring 326.

[0094] A blocking ring 327 is rotatably connected to the inner wall of the feeding pipe 111. Three air jet holes are opened on the inner wall of the blocking ring 327. Two connecting rods 328 are fixedly connected to the side wall of the blocking ring 327. The side walls of the two connecting rods 328 are fixedly connected to the outer wall of the rotating rod 112.

[0095] When the spring ring 215 descends, it causes the arc-shaped plate 322 to descend as well. Once the arc-shaped plate 322 covers the air inlet 323, it compresses the gas inside the arc-shaped block 321. This compressed gas is blocked by the spring-loaded air-blocking block 324, thus increasing the gas pressure. The pressure increases until the protruding part of the arc-shaped plate 322 contacts the spring-loaded air-blocking block 324 during its descent, pushing the block down and accumulating rebound force. After the block down, it releases its obstruction of the gas, allowing the high-pressure gas to enter the exhaust port 325 and then the pressure ring 326. Simultaneously, when the rotating rod 112 rotates, it drives the connecting rod 328 to rotate, which in turn drives the blocking ring 327 to rotate. During the rotation of the blocking ring 327, the second air jet hole inside the blocking ring 327 connects with the first air jet hole inside the pressure ring 326, as follows: Figure 8 As shown in the state of H, high-pressure gas will be ejected from the nozzle 1 and nozzle 2 towards the rotating rod 112. When the falling powder comes into contact with the gas, it will be affected by the gas thrust, causing the powder to move towards the rotating rod 112, so that the powder falls again onto the surface of the auger 113, allowing the auger 113 to transport the powder again, recover the scattered material, and improve the conveying efficiency.

[0096] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0097] A specific application of this embodiment is as follows: When using this invention, the device is installed together with a screw unloader. When it is necessary to unload powder from the ship's hold, the screw unloader inserts the feeding pipe 111 and the pick-up head 122 into the powder material in the ship's hold. Then, the motor 115 is started to drive the pulley group 114 to rotate. The pulley group 114 causes the rotating rod 112 and the screw auger 113 to rotate. Then, the motor 123 is started to drive the gear rod 124 to rotate, causing the gear ring 121 to rotate, which in turn causes the pick-up head 122 to rotate, pushing the powder material in the ship's hold into the feeding pipe 111. The screw auger 113 then contacts the powder and conveys the powder upward.

[0098] As the auger 113 conveys powdered materials, it causes the materials to rotate around the center of the rotating rod 112. Due to centrifugal force, some of the powdered materials move towards the inner wall of the feeding pipe 111. This moving material is blocked by the spiral baffle 211. Simultaneously, the rotation of the rotating rod 112 causes the concave-convex ring 213 to rotate. When the protruding part of the concave-convex ring 213 contacts the spring ring 215, it compresses the spring ring 215, causing it to descend and accumulate rebound force. The descent of the spring ring 215 causes the F-shaped rod 222 to descend as well. 22 will push the sliding frame 221 down, causing the connecting frame 223 to fall. The connecting frame 223 will push the connecting rod 224 to rotate, causing the connecting rod 224 to push the pressing block 225 to move towards the spiral baffle 211. As the concave and convex ring 213 continues to rotate, when the concave position of the concave and convex ring 213 contacts the spring ring 215, the rebound force of the spring ring 215 will be released, causing it to return to its original position, causing the sliding frame 221 to rise, causing the pressing block 225 to return to its original position, until the concave and convex ring 213 presses the pressing block 225 down again. This process is repeated, causing the pressing block 225 to extend and return to its original position.

[0099] When the powder moves to the position of the stop 226, some of the powder will be blocked by the stop 226. When the extrusion block 225 moves towards the spiral baffle 211, it will extrude the powder. The spiral cover plate 212 will block the powder, preventing the powder from overflowing from the top of the spiral baffle 211. Then, the powder continues to be conveyed. When the powder moves to the discharge chute position of the feeding pipe 111, as... Figure 5 As shown in the state of G, the powder will fall into the discharge chute, allowing the material to move along the discharge chute towards the screw unloader. The screw unloader will then discharge the powder material. The screw baffle 211 will block the powder, making it concentrated and reducing the amount of powder falling during the conveying process. Then, the extrusion block 225 will compress the powder, causing it to agglomerate and reducing its looseness and fluidity. When the powder is discharged towards the discharge chute, the amount of powder falling from this location will be reduced, effectively preventing a large amount of powder from falling through the gap between the screw auger 113 and the inner wall of the feeding pipe 111, which would cause powder to accumulate at the bottom of the feeding pipe 111 and affect the powder conveying efficiency.

[0100] Secondly, when the spring ring 215 descends, when the spring ring 215 passes through the air supplement pipe 313, at this time, the bottom of the spring ring 215 is in a sealed state, and the spring ring 215 will be squeezed when it descends. The gas in the air cylinder 214, at this time, the squeezed gas will be blocked by the blocking rod 312, because the spring ring 215 will drive the blocking rod 312 to descend when it descends, with the continuous movement of the blocking rod 312, the blocking rod 312 will be separated from the air jet pipe 311, canceling the blockage of the gas, at this time, the high-pressure gas will enter the air jet pipe 311, and will be sprayed out of the air jet pipe 311 to the powder in the discharge chute, pushing the powder to move, effectively preventing the powder from agglomerating, which will reduce the flowability of the powder, making it difficult to flow in the discharge chute, which may cause the powder to accumulate in the discharge chute, affecting the discharge of the powder;

[0101] Secondly, when the spring ring 215 descends, it will drive the arc plate 322 to descend, when the arc plate 322 covers the air inlet hole 323, it will squeeze the gas in the arc block 321, and the squeezed gas will be blocked by the spring gas blocking block 324, so the gas pressure will increase, until the convex position of the arc plate 322 contacts the spring gas blocking block 324 during the descending process, which will drive the spring gas blocking block 324 to descend, making it accumulate the rebound force, after the spring gas blocking block 324 descends, it will cancel the blockage of the gas, allowing the high-pressure gas to enter the exhaust hole 325, and then enter the air pressure ring 326 through the exhaust hole 325, at the same time, when the rotating rod 112 rotates, it will drive the connecting rod 328 to rotate, and then drive the blocking ring 327 to rotate through the connecting rod 328, when the blocking ring 327 rotates, the air jet hole two inside the blocking ring 327 and the air jet hole one inside the air pressure ring 326 are connected, as shown in the state of H in the middle, the high-pressure gas will be sprayed out of the air jet hole one and the air jet hole two towards the direction of the rotating rod 112, when the falling powder contacts the gas, it will be affected by the gas thrust, making the powder move towards the direction of the rotating rod 112, so that the powder falls again on the surface of the spiral auger 113, making the spiral auger 113 transport the powder again, recycling the scattered material and improving the transportation efficiency; Figure 8

[0102] Secondly, the connecting rod 328 will make the spraying position of the air jet hole two always above the spiral auger 113, so that the gas is sprayed above the spiral auger 113, which is convenient for the falling powder material to move to the surface of the spiral auger 113, effectively preventing the spiral auger 113 from rotating, and the gas from being sprayed, which will push the falling powder into contact with the spiral baffle 211, the gas will generate a strong thrust, causing a small amount of powder to adhere to the surface of the spiral baffle 211, when there is a lot of powder adhering to the surface of the spiral baffle 211, it may cause the spiral baffle 211 to rotate, and the powder to rub against the wall of the feeding pipe 111, part of the powder will fall off during the rubbing process, allowing the powder to enter the air pressure ring 326, causing the air pressure ring 326 to be blocked, affecting the discharge of the gas; ​

[0103] Wherein, after the spring ring 215 resets, the air supplement pipe 313 will be in communication with the inside of the air cylinder 214, so that the outside air enters the air cylinder 214 to supplement the air, and after the spring ring 215 resets, the arc-shaped plate 322 is reset to make the air inlet hole 323 in communication with the inside of the arc-shaped block 321 to supplement the air.
