When one end of the first movable shaft 58 moves to a certain position inside the second conveying shaft 55, the first movable shaft 58 is connected to the second convex rib through the groove 513 to drive the second conveying shaft 55 to rotate. The first movable shaft 58 and the second movable shaft 59 are connected by a synchronization rod 510; the feeding pipe 7 is connected to the feeding pipe 3;The middle part of the feed box 1 is provided with a partition to divide it into two parts, which are respectively connected to the feed pipe 3 and the return pipe 4. The bottom of the part of the feed box 1 connected to the feed pipe 3 is in a closed state, and the bottom of the part of the feed box 1 connected to the return pipe 4 is in an open and closed state. The outer sides of the first conveying shaft 52 and the second conveying shaft 55 are both provided with forward blades for feeding. A motor 51 is fixed to one side of the mixing box 2, and a first fixed shaft 56 is installed on the output end of the motor 51. A fixed seat 53 is fixed to one side of the mixing box 2, and a second fixed shaft 57 is rotated on the fixed seat 53. The first movable shaft 58 is installed on the second fixed shaft 57. The first fixed shaft 56 is connected to the second fixed shaft 57 through a synchronous belt 511. The fixed seat 5 A hydraulic rod connected to the synchronization rod 510 at its output end is fixed on one side of 3. The second movable shaft 59 and the first movable shaft 58 are rotatably mounted on the synchronization rod 510. Second ribs on the outside of the first movable shaft 58 are distributed at one end and the middle part, and the second rib in the middle part of the first movable shaft 58 is connected through the stirring shaft 54. When the second rib on one end of the first movable shaft 58 is connected to the groove 513, the first movable shaft 58 drives the second conveying shaft 55 to rotate through the second rib. When the first rib on the second movable shaft 59 is connected to the first conveying shaft 52, the first conveying shaft 52 is driven to rotate. When the first rib on the second movable shaft 59 moves into the empty groove 512, it moves relative to the first conveying shaft 52.

[0029] See Figures 1 to 7 As shown, the shield slag enters from the feed box 1. Due to the design of the partition, the shield slag will not enter the outside of the second conveying shaft 55. When the first-level stirring is performed initially: the first fixed shaft 56 is driven to rotate by the output end of the motor 51, and the first fixed shaft 56 drives the second movable shaft 59 to rotate. The second movable shaft 59 drives the first conveying shaft 52 to rotate through the first convex rib. The first conveying shaft 52 drives the shield slag from the feed box 1 to the mixing box 2 through the outer forward blades. At this time, the shield slag inside the feed pipe 3 can be sprayed with additives through the feeding pipe 7. Through the cooperation of the first conveying shaft 52 and the feeding pipe 7, the additives can be evenly sprayed at each place during the shield slag feeding process, avoiding uneven additives, resulting in different additive amounts at different places in the shield slag, and affecting its subsequent processing.

[0030] At the same time, in the process of feeding the shield slag through the first conveying shaft 52 and spraying the additive, the additive can be sprayed evenly to achieve a better dispersion effect, and at the same time, the shield slag and the additive can be mixed more fully, thereby improving the mixing effect of the additive and the shield slag;

[0031] In addition, the motor 51 drives the first fixed shaft 56 to rotate, the first fixed shaft 56 drives the second fixed shaft 57 to rotate, and the second fixed shaft 57 drives the first movable shaft 58 to rotate. At this time, the first movable shaft 58 only drives the stirring shaft 54 ​​to rotate without driving the second conveying shaft 55 to rotate, so that the shield muck entering the mixing box 2 can be stirred by the stirring shaft 54, thereby completing the first stage of stirring of the shield muck; at the same time, further improving the fusion effect of the additives and the shield muck; making the secondary mixing more thorough and the effect better;

[0032] After a certain amount of shield slag is processed in the first stage inside the mixing box 2, when the secondary mixing is carried out: the synchronous rod 510 is driven to move by the hydraulic rod, and the synchronous rod 510 drives the second movable shaft 59 and the first movable shaft 58 to move. At this time, the first convex rib on the second movable shaft 59 moves to the empty groove 512. At this time, the second movable shaft 59 no longer drives the first conveying shaft 52 to rotate, and the first conveying shaft 52 cannot carry out shield slag feeding; at the same time, the second convex rib on one end of the first movable shaft 58 is connected to the groove 513, and the first movable shaft 58 drives the second movable shaft 59 through the second convex rib The conveying shaft 55 rotates, and the second conveying shaft 55 rotates to transport the shield slag after the primary stirring inside the mixing box 2 to the inside of the feed box 1 for subsequent processing, and can load the shield slag inside the return pipe 4 and perform secondary stirring, thereby automatically performing the primary stirring and secondary stirring of the shield slag, which can greatly improve the uniformity of its stirring and improve the effect of its subsequent processing; through the above-mentioned multi-stage stirring, additives and water can be added in appropriate amounts, and can be mixed more evenly with the shield slag; greatly improving the processing of the shield slag;

[0033] The cooling assembly 6 is installed on one side of the feed box 1 and cooperates with the stirring mechanism 5 to optimize the stirring work; the cooling assembly 6 includes a first storage barrel 61 located on one side of the feed box 1, and a threaded shaft 63 is passed through the interior of the first storage barrel 61. When the first conveying shaft 52 rotates, the threaded shaft 63 moves along the first conveying shaft 52, and a piston disk 65 sliding inside the first storage barrel 61 is installed on the threaded shaft 63. A return air pipe 64 is installed on one side of the first storage barrel 61, and both ends are connected to the first storage barrel 61. The two connecting points of the return air pipe 64 and the first storage barrel 61 are respectively located on both sides of the piston disk 65. The cooling assembly 6 also includes a second storage barrel 62 located on one side of the feed box 1, and a push rod 66 that moves following the threaded shaft 63 is passed through the second storage barrel 62. An adjusting block 67 extending to the inside of the second conveying shaft 55 is installed on one end of the push rod 66. The outer side of the adjusting block 67 is an inclined surface, and a water outlet is provided on one end of the second conveying shaft 55. Figure 8 As shown, an air inlet is provided at one end of the first conveying shaft 52;

[0034] See Figures 3 to 8As shown, when the shield slag is stirred at the first level, the first conveying shaft 52 rotates. Since the inner thread of the first conveying shaft 52 is connected to the threaded shaft 63 through a ball nut pair, when the first conveying shaft 52 stirs the shield slag at the first level, the threaded shaft 63 moves along the axis of the first conveying shaft 52. At the same time, the threaded shaft 63 drives the piston plate 65 to move, and the piston plate 65 squeezes the gas inside the first storage barrel 61. When the first level of stirring is about to end, when one end of the threaded shaft 63 moves to a certain position inside the first conveying shaft 52, the closed state between one end of the threaded shaft 63 and one end of the first conveying shaft 52 is cancelled. At this time, the interior of the first conveying shaft 52 is connected to the interior of the first storage barrel 61. At this time, the cooling gas inside the first storage barrel 61 will enter the interior of the first conveying shaft 52, so that the first conveying shaft 52 after the first level of stirring of the shield slag can be cooled, thereby improving the service life of the first conveying shaft 52. In addition, the cooling gas can be selected according to actual conditions. For example, low-temperature nitrogen at -20°C can quickly cool down.

[0035] When performing secondary stirring, the second conveying shaft 55 rotates to perform secondary stirring on the shield slag inside the return pipe 4 and feed it into the feed box 1. At this time, the threaded shaft 63 has driven the push rod 66 to move to a certain position, and the push rod 66 drives the adjusting block 67 to move to a certain position. Since the outer side of the adjusting block 67 is designed with an inclined surface, the amount of water entering through the second fixed shaft 57 can be controlled. While the second conveying shaft 55 rotates to perform secondary stirring on the shield slag inside the return pipe 4, water is injected through the gap between the adjusting block 67 and the inside of the second conveying shaft 55. While the water cools it down through the inside of the second conveying shaft 55, it flows out from the water outlet after flowing to the other end of the second conveying shaft 55, thereby humidifying the shield slag before the secondary stirring; so that it reaches a uniform plastic state, and the continuous rotation of the stirring shaft 54, combined with the two-stage feeding and stirring of the second conveying shaft 55 and the first conveying shaft 52, can further improve the uniformity of the shield slag.

[0036] Working principle: Shield slag enters from the feed box 1. Due to the design of the partition, the shield slag will not enter the outside of the second conveying shaft 55. When the first-level stirring is performed initially: the first fixed shaft 56 is driven to rotate by the output end of the motor 51, and the first fixed shaft 56 drives the second movable shaft 59 to rotate. The second movable shaft 59 drives the first conveying shaft 52 to rotate through the first convex rib. The first conveying shaft 52 drives the shield slag from the feed box 1 to the mixing box 2 through the outer forward blades. At this time, additives can be sprayed on the shield slag inside the feed pipe 3 through the feeding pipe 7. Through the cooperation of the first conveying shaft 52 and the feeding pipe 7, additives can be evenly sprayed at every place during the shield slag feeding process.

[0037] In addition, the motor 51 drives the first fixed shaft 56 to rotate, the first fixed shaft 56 drives the second fixed shaft 57 to rotate, and the second fixed shaft 57 drives the first movable shaft 58 to rotate. At this time, the first movable shaft 58 only drives the stirring shaft 54 ​​to rotate without driving the second conveying shaft 55 to rotate. As a result, the shield-bored soil entering the mixing box 2 can be stirred by the stirring shaft 54, thereby completing the first stage of stirring of the shield-bored soil.

[0038] After a certain amount of shield slag is processed in the first stage inside the mixing box 2, when the secondary mixing is carried out: the synchronous rod 510 is driven to move by the hydraulic rod, and the synchronous rod 510 drives the second movable shaft 59 and the first movable shaft 58 to move. At this time, the first convex rib on the second movable shaft 59 moves to the empty groove 512. At this time, the second movable shaft 59 no longer drives the first conveying shaft 52 to rotate, and the first conveying shaft 52 cannot load the shield slag; at the same time, the second convex rib on one end of the first movable shaft 58 is connected to the groove 513, and the first movable shaft 58 drives the second conveying shaft 55 to rotate through the second convex rib. The rotation of the second conveying shaft 55 can transfer the shield slag after the primary mixing in the mixing box 2 to the inside of the feeding box 1 for subsequent processing, and can load the shield slag in the return pipe 4 and perform secondary mixing, thereby automatically performing the primary mixing and secondary mixing of the shield slag, which can greatly improve its mixing uniformity and improve the effect of its subsequent processing;

[0039] During the first-stage stirring of the shield slag, when the first conveying shaft 52 rotates, since the inner thread of the first conveying shaft 52 is connected to the threaded shaft 63 through a ball nut pair, when the first conveying shaft 52 stirs the shield slag for the first stage, the threaded shaft 63 moves along the axis of the first conveying shaft 52, and at the same time, the threaded shaft 63 drives the piston plate 65 to move, and the piston plate 65 squeezes the gas inside the first storage barrel 61. When the first-stage stirring is about to end, when one end of the threaded shaft 63 moves to a certain position inside the first conveying shaft 52, one end of the threaded shaft 63 will cancel the closed state with one end of the first conveying shaft 52. At this time, the interior of the first conveying shaft 52 will be connected to the interior of the first storage barrel 61. At this time, the cooling gas inside the first storage barrel 61 will enter the interior of the first conveying shaft 52, so that the first conveying shaft 52 after the first-stage stirring of the shield slag can be cooled, thereby improving the service life of the first conveying shaft 52.

[0040] When performing secondary stirring, the second conveying shaft 55 rotates to perform secondary stirring on the shield slag inside the return pipe 4 and feed it into the feed box 1. At this time, the threaded shaft 63 has driven the push rod 66 to move to a certain position, and the push rod 66 drives the adjusting block 67 to move to a certain position. Since the outer side of the adjusting block 67 is designed with an inclined surface, the amount of water entering through the second fixed shaft 57 can be controlled. While the second conveying shaft 55 rotates to perform secondary stirring on the shield slag inside the return pipe 4, water is injected through the gap between the adjusting block 67 and the inside of the second conveying shaft 55. While the water cools it down through the inside of the second conveying shaft 55, it flows out from the water outlet after flowing to the other end of the second conveying shaft 55, thereby humidifying the shield slag before the secondary stirring; so that it reaches a uniform plastic state, and the continuous rotation of the stirring shaft 54, combined with the two-stage feeding and stirring of the second conveying shaft 55 and the first conveying shaft 52, can further improve the uniformity of the shield slag.
