[0026] See also Figure 1-5 A pneumatic conveying stabilization device includes a conveying pipeline 1, which is fixedly connected to an air supply pipe 2. One end of all the air supply pipes 2 is connected to a high-pressure main pipeline. When blockage occurs inside the conveying pipeline 1, the high-pressure main pipeline introduces high-pressure gas into the conveying pipeline 1 through the air supply pipe 2, thereby achieving the effect of reducing the blockage of the conveying pipeline 1. An automatic air supply component 100 is provided on the air supply pipe 2. A protection box 3 is fixedly connected to the conveying pipeline 1 on one side of the air supply pipe 2. A sealing door panel 4 is rotatably connected to one side of the protection box 3 through a hinge, and a dredging component 200 is installed inside the protection box 3.

[0027] The dredging component 200 includes an electric push rod 201 symmetrically fixedly mounted on the top wall of the protection box 3. The input end of the electric push rod 201 is connected to the battery through an external cable. The output ends of the two electric push rods 201 are fixedly mounted with the same sealing plate 202. The sealing plate 202 is used to seal the connection between the bottom of the protection box 3 and the conveying pipe 1 when there is no blockage. The top of the sealing plate 202 is symmetrically fixedly mounted with a support rod 203. The upper end surfaces of the two support rods 203 are fixedly mounted with the same storage box 204. A driving motor 205 is fixedly mounted on one side of the storage box 204. A protective box is provided on the outside of the driving motor 205. The input end of the driving motor 205 is connected to the battery through an external cable, and the output end of the driving motor 205 passes through the interior of the storage box 204 through a bearing and is fixedly installed with a screw rod 206.

A driving toothed pulley 210 is fixedly installed on the top of the driven bevel gear 209. An extension box 211 is fixedly installed on one side of the sliding block 207. One end of the extension box 211 movably passes through the outside of the storage box 204, and the top of one side of the extension box 211 is rotatably connected to the outside of the storage box 204. The wall is rotatably connected to a driven toothed pulley 212, a toothed synchronous belt 213 is installed between the driving toothed pulley 210 and the driven toothed pulley 212, an extension rod 214 is fixedly installed on the toothed synchronous belt 213, and one side of the top of the extension rod 214 is fixedly installed on the toothed synchronous belt 213 through a connecting block, and a clearing component 300 is installed at one end of the extension rod 214. The clearing component 200 can effectively drive the clearing component 300 to extend to the blocked position for clearing. When it is necessary to drive the clearing component 300 to extend to the blocked position for clearing, the electric push rod 201 is started to drive the storage box 204 to descend to the conveying pipeline. 1, and then start the driving motor 1 205 to drive the screw rod 206 to rotate. The screw rod 206 drives the extension box 211 on the side of the sliding block 207 to move while rotating, and at the same time drives the driving bevel gear 208 to rotate. The driving bevel gear 208 drives the driving toothed belt pulley 210 on the driven bevel gear 209 to rotate. The driving toothed belt pulley 210 drives the driven toothed belt pulley 212 to rotate through the toothed synchronous belt 213. The top of the extension rod 214 is fixedly installed on the driven toothed belt pulley 212, thereby driving the extension rod 214 to move, thereby driving the clearing assembly 300 to extend to the blocked position in the conveying pipeline 1 for clearing.

[0028] Example 2:

[0029] See also Figure 1-5, this embodiment provides a technical solution based on the first embodiment: the unblocking component 300 includes a fixed box 301 fixedly installed at one end of the second extension frame 215, a second drive motor 302 is fixedly installed inside the fixed box 301, the input end of the second drive motor 302 is connected to the battery through an external cable, the output end of the second drive motor 302 passes through the outside of the fixed box 301 through a bearing and is fixedly installed with a rotating rod 303, a dredging rod 304 is fixedly installed on the outer surface of the rotating rod 303, the automatic air supply component 100 includes an air pressure tube 101 fixedly connected to the conveying pipeline 1, a piston plate 102 is slidably connected to the air pressure tube 101, the piston plate 102 matches the inner wall of the air pressure tube 101, and a piston plate 102 is fixedly installed on the top of the piston plate 102. The outer surface of the sliding rod 103 is located inside the air pressure tube 101 and is provided with a spring 105. The air supply tube 2 is rotatably connected to a sealing plate 106 that matches the inner wall of the air supply tube 2. One side of the sealing plate 106 passes through the outside of the air supply tube 2 through a connecting rod and is fixedly provided with a driving gear 107 that is meshed with the rack 104. A sensor 108 is fixedly installed on the inner wall of the air supply tube 2. When the sealing plate 106 completely blocks the air supply tube 2, one side of the sealing plate 106 contacts the sensor 108. The automatic air supply component 100 can effectively perform automatic air supply dredging when the delivery pipeline 1 is blocked. When the delivery pipe 1 is blocked and the air is automatically replenished and unblocked, the local air pressure in the delivery pipe 1 rises. At this time, due to the pressure increase on the side of the piston plate 102 close to the delivery pipe 1, the piston plate 102 in the air replenishment pipe 2 moves in the direction away from the delivery pipe 1, thereby driving the rack 104 on the top of the sliding rod 103 to move. Because the rack 104 is meshed with the driving gear 107, the blocking plate 106 at one end of the driving gear 107 is driven to rotate, thereby rotating the blocking plate 106. After the blocking plate 106 rotates, the air replenishment pipe 2 is connected, and the high-pressure main pipeline transports high-pressure gas to the delivery pipe 1, thereby automatically replenishing and unblocking the delivery pipe 1 when it is blocked. The screw rod 206 thread penetrates the driving bevel gear 208 and the sliding block 20 On one side of 7, the bottom wall of the sliding block 207 fits with the bottom wall of the storage box 204, the driving bevel gear 208 and the driven bevel gear 209 are meshed and connected, the driving toothed pulley 210 and the driven toothed pulley 212 are connected through a toothed synchronous belt 213, the extension rod 214 slides through to the side of the extension box 211, a connecting rod is fixedly installed on one side of the storage box 204, the screw rod 206 is rotated away from one end of the driving motor 205 and is connected to one side of the connecting rod, a groove 5 for easy movement is opened at the bottom of the extension box 211, a telescopic plate 6 is fixedly installed on the moving groove 5, a controller is provided on one side of the air supply pipe 2, and the driving motor 1 205, the electric push rod 201, the driving motor 2 302 and the sensor 108 are all electrically connected to the controller.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] During operation, when the delivery pipe 1 is partially blocked, the local air pressure rises. At this time, the pressure on the side of the piston plate 102 close to the delivery pipe 1 increases, causing the piston plate 102 in the air supply pipe 2 to move away from the delivery pipe 1, thereby driving the rack 104 on the top of the sliding rod 103 to move. Because the rack 104 is meshed with the driving gear 107, it drives the blocking plate 106 at one end of the driving gear 107 to rotate, thereby rotating the blocking plate 106. After the blocking plate 106 rotates, the air supply pipe 2 is connected, and the high-pressure main pipeline transports high-pressure gas into the delivery pipe 1, thereby automatically replenishing air and clearing the delivery pipe 1 when it is blocked. At the same time, when the blocking plate 106 rotates, the sensor 108 cannot sense the blocking plate 106, and then the electric push rod 201 is started by the controller. The storage box 204 is driven to descend into the conveying pipe 1, and then the driving motor 1 205 is started to drive the screw rod 206 to rotate. While rotating, the screw rod 206 drives the extension box 211 on the side of the sliding block 207 to move, and at the same time drives the driving bevel gear 208 to rotate. The driving bevel gear 208 drives the driving toothed belt pulley 210 on the driven bevel gear 209 to rotate. The driving toothed belt pulley 210 drives the driven toothed belt pulley 212 to rotate through the toothed synchronous belt 213, and is fixedly installed on the driven toothed belt pulley 212 through the top of the extension rod 214, thereby driving the extension rod 214 to move, thereby driving the unblocking component 300 to extend to the blocked position in the conveying pipe 1, and then starting the driving motor 2 302 to drive the dredging rod 304 for further dredging, thereby achieving pneumatic stable conveying.
