[0030] Embodiment 1

[0031] like Figure 1 to Figure 2As shown, a soil improvement medium conveying device according to an embodiment of the present invention comprises a fixed seat 1; a conveying box 11 is fixedly connected to the outside of the fixed seat 1; a material leakage port is opened at the top of the conveying box 11; a servo motor 12 is fixedly connected to the inside of the fixed seat 1; a connecting shaft 13 is fixedly connected to the output end of the servo motor 12, and the connecting shaft 13 is located inside the conveying box 11; a spiral blade 14 is fixedly connected to the outside of the connecting shaft 13; two sets of fixing rings 15 are fixedly connected to the outside of the connecting shaft 13 near the servo motor 12; a plurality of blowing The fan blade 16; the outside of the fan blade 16 is equipped with an electric heating wire; the current shield machine usually uses a shaft screw conveyor to transport the slag during tunnel excavation, but because the shield machine is prone to encounter moisture underground during excavation, some moist slag will be excavated, and when the shaft screw conveyor is transporting moist slag, some of the slag will adhere to the spiral blades, resulting in an increase in the load of the screw conveyor, and even accumulation and blockage when transporting the slag. Therefore, the specific implementation method of the embodiment of the present invention is to use the fixed seat 1 as the fixed support of the servo motor 12, and the conveying box 11 and the fixed seat 1 The two groups of fixed rings 15 fixed to the outside of the connecting shaft 13 rotate accordingly, and multiple groups of blowing fan blades 16 rotate to draw air from the air outlet of the conveying box 11 into the interior of the conveying box 11, generating wind force to blow air forward. The blowing fan blades 16 are equipped with electric heating wires to generate heat energy, so that hot air flows in the conveying box 11, and the wet slag leaking from the conveying box 11 is dried by the hot air, and part of the slag is dried. When the connecting shaft 13 rotates, it drives the spiral blades 14 to promote the transportation of the slag. When the slag enters the leakage port of the conveying box 11, the bacterium subtilis, polymyxin and nystatin are also added from the leakage port of the conveying box 11, and are stirred and mixed with the slag along with the spiral blades 14, which plays a role in improving the fermentation medium of the slag. At the same time, when the blowing fan blades 16 rotate to blow hot air, the conveying box 11 is used to wrap the slag, and the spiral blades 14 are used to stir the slag, so as to further improve the drying and mixing effect of the wet slag.

[0032] like Figures 2 to 4As shown, the outside of the connecting shaft 13 is fixedly connected with multiple sets of fixing frames 2, and are located at the spiral blades 14; the outside of the fixing frame 2 is fixedly connected with a connecting seat 21; the outside of the connecting seat 21 is fixedly connected with multiple sets of cutting blades 22; when a large amount of wet slag is transported inside the conveying box 11, since the wet slag is easy to stick together into blocks and is easy to cause blockage after being dried inside the conveying box 11, the slag is transported by the spiral blades 14. Therefore, the connecting shaft 13 rotates to drive the fixing frame 2 to rotate at the same time, and the multiple sets of cutting blades 22 on the connecting seat 21 cut the transported slag, so that the block slag is cut into small pieces, thereby reducing the block slag. The situation of block slag forming blockage.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, the outside of the spiral blade 14 is fixedly connected with multiple groups of fixed shafts 3; the outside of the fixed shaft 3 is fixedly connected with multiple groups of flow sheets 31; the shape of the flow sheet 31 is curved; when part of the slag is transported at the spiral blade 14, since part of the slag cannot be completely cut, the fixed shaft 3 fixed to the outside of the spiral blade 14 is used as a support rod, and the multiple groups of flow sheets 31 are fixed to the outer surface of the fixed shaft 3, and the arc of the flow sheet 31 is relied on to penetrate the slag blocks and slag balls, thereby breaking the slag blocks and slag balls, reducing the residual block slag, thereby improving the effect of the slag improvement medium, and at the same time, the rotation of the multiple groups of flow sheets 31 can be used to scrape out the debris in the slag, which is convenient for subsequent cleaning.

[0034] like Figure 2 and Figure 6 As shown, a plurality of storage grooves are opened inside the spiral blade 14; a plurality of knocking balls 4 are placed inside the spiral blade 14 and are located in the storage grooves; when transporting partially sticky debris, since some of the debris will adhere to the outer wall of the spiral blade 14, excessive adhesion of the debris will affect the transporting effect of the spiral blade 14, so a plurality of storage grooves are opened inside the spiral blade 14, and knocking balls 4 are placed in each storage groove. When the spiral blade 14 rotates with the connecting shaft 13, the knocking balls 4 shake up and down inside the spiral blade 14 and knock on the inner wall of the spiral blade 14, which is transmitted to the outer wall of the spiral blade 14 to generate vibration, so as to achieve the effect of vibrating the outer wall of the spiral blade 14 to remove the debris, thereby improving the transporting effect of the debris.

[0035] The spiral blade 14 is provided with an overflow groove 5 inside and located at the storage groove; a sealing block 51 is fixed inside the spiral blade 14 and located at the overflow groove 5; when conveying the slag with strong adhesion, since the slag adheres to the outer wall of the spiral blade 14 and is difficult to clean, a small amount of lubricating oil, as well as liquids of Bacillus subtilis, polymyxin and nystatin are poured into the storage groove in advance, and when the spiral blade 14 rotates, the sealing block 51 is provided with fine holes, and the lubricating oil overflows from the small holes of the sealing block 51 to the outside. The flow adheres to the outer wall of the spiral blade 14. The adhered debris is affected by the lubricating oil and its adhesion is reduced, thereby reducing the situation of debris adhering to the outer wall of the spiral blade 14. The liquids of thallus, polymyxin and nystatin will also be discharged and mixed with the debris for fermentation, thereby improving the effect of medium improvement. At the same time, the overflow groove 5 is opened in an L shape. When the debris enters the small hole, it will not directly enter the storage tank. When the lubricating oil flows back, it will impact the debris and discharge it, thereby sealing the debris and reducing the blockage of the holes in the sealing block 51.

[0036] A plurality of metal strips 6 are fixedly connected to the interior of the spiral blade 14; the metal strips 6 and the knocking balls 4 fit together; when the knocking balls 4 are stored inside the spiral blade 14, as the spiral blade 14 rotates, the knocking balls 4 are driven to slide on the inner wall of the spiral blade 14, and the plurality of metal strips 6 and the knocking balls 4 are driven to rub against each other. The metal strips 6 generate heat energy after being rubbed for a long time, which is then conducted to the outer wall of the spiral blade 14, thereby heating the outer wall of the spiral blade 14 and drying the slag attached to the outer wall of the spiral blade 14, further reducing the adhesion effect of the slag, and at the same time improving the fermentation medium of the slag.

[0037] like Figures 1 to 3 As shown, the interior of the conveying box 11 is fixedly connected with a material guide box 7, and is located at the material leakage port; the interior of the material guide box 7 is fixedly connected with a guide plate 71; the interior of the guide plate 71 is fixedly connected with a filter screen plate 72; when the slag is introduced into the interior of the conveying box 11 from the material leakage port at the top of the conveying box 11, since there will be more large pieces of debris in the slag, which will affect the conveying of the spiral blades 14, the material guide box 7 is used as a guide, and the slag falls on the guide plate 71 and the filter screen plate 72 when entering the interior of the material guide box 7. The filter screen plate 72 filters larger debris, thereby reducing the possibility of debris clogging the interior of the conveying box 11.

[0038] A magnetic block 8 is fixedly connected to the outside of the spiral blade 14 and is located below the material guide box 7; a spring piece 81 is fixedly connected to the outside of the filter screen plate 72; a magnetic ball 82 is fixedly connected to the outside of the spring piece 81; the magnetic block 8 and the magnetic ball 82 can attract each other when they are close to each other; when larger block slag is stuck in the hole of the filter screen plate 72, the spiral blade 14 is used to rotate to drive the magnetic block 8 to approach the magnetic ball 82, and the magnetic block 8 is magnetically attracted to the magnetic ball 82, and the spring piece 81 is pulled and bent by the magnetic ball 82. When the spiral blade 14 continues to rotate and drives the magnetic block 8 away from the magnetic ball 82, the spring piece 81 drives the magnetic ball 82 to reset and rebound, knocking and vibrating the outer wall of the filter screen plate 72, thereby achieving the effect of vibrating and cleaning the block slag.

[0039] A friction plate 9 is fixedly connected to the inside of the filter screen plate 72; the friction plate 9 is located above the magnetic ball 82; when the magnetic ball 82 strikes and vibrates the filter screen plate 72 for a long time, the filter screen plate 72 is easily damaged by the strikes, so the friction plate 9 is fixed to the middle position of the filter screen plate 72, and the friction plate 9 is used to replace the filter screen plate 72 and strike the magnetic ball 82, thereby reducing the wear of the filter screen plate 72. At the same time, the friction plate 9 is tightly connected to the filter screen plate 72, and a strong vibration is generated when the magnetic ball 82 strikes the friction plate 9, thereby improving the filtering effect of the filter screen plate 72.

[0040] Embodiment 2

[0041] like Figure 7 As shown, compared with Example 1, another embodiment of the present invention is: a scraper plate 91 is fixedly connected to the outside of the spiral blade 14; the scraper plate 91 is in the shape of a blade; when the spiral blade 14 rotates inside the conveying box 11 to convey the debris, since the debris is easily accumulated inside the conveying box 11, a large amount of accumulation may cause blockage, so the scraper plate 91 is fixed to the outer wall of the spiral blade 14, and when the spiral blade 14 rotates, the scraper plate 91 is driven to scrape the debris at the same time, thereby playing the role of scraping and conveying the debris.

[0042] During the working process, first, the output end of the servo motor 12 rotates on the side of the fixed seat 1, driving the connecting shaft 13 to rotate inside the conveying box 11. The connecting shaft 13 drives the spiral blades 14 and the fixed ring 15 to rotate at the same time, and multiple sets of fan blades 16 rotate to blow air into the conveying box 11, and cooperate with the electric heating wire to generate heat energy. The slag falls from the guide box 7 and falls on the guide plate 71 and the filter screen 72. The large pieces of debris in the slag are filtered by the filter screen 72, and then fall into the inside of the conveying box 11 and are dried by the hot air. The spiral blades 14 rotate to spirally convey the slag, and the magnetic block 8 intermittently attracts the magnetic ball 82. As the spring piece 81 pulls the magnetic ball 82 to reset its elastic force, it hits the friction plate 9 to generate a strong The strong vibration shakes the debris stuck on the filter plate 72 to the inside of the conveying box 11. In the process of the spiral blade 14 rotating to convey the debris, the multiple groups of cutting blades 22 cut the debris, and the multiple groups of flow slices 31 break the debris blocks. The subtilis fungus, polymyxin and nystatin are mixed in the debris to improve the medium improvement effect on the debris. At the same time, in the process of the spiral blade 14 rotating, the knocking ball 4 continuously knocks on the inside of the spiral blade 14 to reduce the adhesion of the debris on the outer wall of the spiral blade 14. The lubricating oil overflows from the blocking block 51 to further reduce the adhesion of the debris. The knocking ball 4 cooperates with the multiple groups of metal strips 6 to generate heat energy through long-term continuous friction, thereby improving the drying effect of the debris on the outer wall of the spiral blade 14.
