Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0025] Referring to Figures 1-3 , a double-liquid grouting machine comprises:

[0026] The rack body 1 is provided with two storage tanks 2, and the top of each storage tank 2 is communicated with a liquid injection pipe, through which the corresponding raw materials can be injected into the two storage tanks 2, facilitating the subsequent mixing of the two raw materials.

[0027] The conveying assembly and the stirring assembly include communication pipes 3, a stirring box 5, a stirring motor 6, a stirring shaft 7, a gear assembly 9, rotating shafts 10, and helical conveying blades 11. The two communication pipes 3 are communicated at the bottom of the storage tanks 2 one by one, and each of the two communication pipes 3 is installed with an electromagnetic valve 4 at the end close to the storage tank 2. When the electromagnetic valve 4 is turned on, the raw materials in the storage tank 2 can flow outwards through the communication pipe 3, facilitating the subsequent mixing of the two raw materials.

[0028] The stirring box 5 is fixedly connected to the middle part of the rack body 1, and the two communication pipes 3 are communicated at the two sides of the stirring box 5 away from the storage tanks 2. The two communication pipes 3 are both meandering pipes and are symmetrically arranged. The stirring motor 6 is installed at the top outside of the stirring box 5, and the output end of the stirring motor 6 is coaxially fixedly connected with the stirring shaft 7. The end of the stirring shaft 7 away from the stirring motor 6 is sealingly penetrated into the stirring box 5 and is connected with the gear assembly 9 at the part of the stirring shaft 7 extending into the stirring box 5. The two output ends of the gear assembly 9 are both connected with the rotating shafts 10, and the ends of the two rotating shafts 10 away from the gear assembly 9 extend into the communication pipes 3 and are both coaxially fixedly connected with the helical conveying blades 11. The helical conveying blades 11 are gap-rotationally matched with the inner wall of the communication pipe 3. When the stirring motor 6 works, the output end of the stirring motor 6 rotates to drive the stirring shaft 7 to rotate. The stirring shaft 7 rotates to drive the two rotating shafts 10 to rotate through the gear assembly 9. The rotating shafts 10 rotate to drive the helical conveying blades 11 to rotate. Under the rotating pushing action of the helical conveying blades 11, the raw materials in the storage tanks 2 are sucked and pushed into the stirring box 5, facilitating the subsequent stirring and mixing of the two raw materials.

[0029] The gear assembly 9 includes a gear box 91, a first bevel gear 92, and a second bevel gear 93. The gear box 91 is sealingly rotationally matched with the stirring shaft 7 and the two rotating shafts 10. The first bevel gear 92 and the second bevel gear 93 are both located in the gear box 91. The stirring shaft 7 is coaxially fixedly connected with the first bevel gear 92. The two rotating shafts 10 are both coaxially fixedly connected with the second bevel gears 93. The first bevel gear 92 is meshed with the two second bevel gears 93 at the two sides thereof. The stirring shaft 7 rotates to drive the first bevel gear 92 to rotate, which drives the two second bevel gears 93 to rotate, thereby driving the two rotating shafts 10 to rotate, improving the power for the helical conveying blades 11 to work.

The input end of the gas pump 21 is communicated with the sealing groove 18. The sealing groove 18 is communicated with an air inlet pipe 22, and the air inlet pipe 22 is provided with an air inlet valve 23. When the gas pump 21 works, the gas pump 21 pumps the sealing groove 18 to reduce the air pressure in the sealing groove 18, so as to overcome the elastic force of the fixed spring 20 to pull the sealing sliding block 19 to slide away from the inner wall of the communication pipe 3 under the action of the air pressure, so that the pushing effect of the part of the spiral conveying blade 11 corresponding to the sealing sliding block 19 on the raw materials is reduced, the output speed of the two raw materials is different, and finally the mixing ratio of the two raw materials is adjusted.

[0033] The plurality of fixed springs 20 have different elastic coefficients, so that under different air pressures in the sealing groove 18, a corresponding number of sealing sliding blocks 19 are separated from the inside of the communication pipe 3, the fine control of the mixing ratio of the two raw materials is improved, the sealing sliding block 19 is arc-shaped near the side close to the inside of the communication pipe 3, and the inner side of the sealing sliding block 19 is flush with the inner wall of the communication pipe 3.

[0034] The grouting assembly comprises a grouting barrel 14, a screw pump 15 and a mixer 16, the grouting barrel 14 is fixedly connected at the bottom of the frame body 1, the screw pump 15 is arranged in the grouting barrel 14, a liquid conveying pipe 13 is communicated between the input end of the grouting barrel 14 and the bottom of the stirring box 5, the output end of the grouting barrel 14 is communicated with the mixer 16, and the output end of the mixer 16 is communicated with a grouting pipe; the mixed raw materials are input into the grouting barrel 14 through the liquid conveying pipe 13, the mixed raw materials are pushed outwards by the screw pump 15, and the grouting operation is completed.

[0036] Meanwhile, the stirring shaft 7 drives the axial blades 8 to rotate, the axial blades 8 rotate to form an axial stirring and mixing effect on the two kinds of raw materials in the stirring box 5, the two rotating shafts 10 drive the two radial blades 12 to rotate, the two radial blades 12 rotate to push the two kinds of raw materials to flow, the mixing of the two kinds of raw materials is accelerated, and the mixing effect of the two kinds of raw materials is improved.

[0037] When it is necessary to control the mixing ratio of the two kinds of raw materials, the air pump 21 is started, the input end of the air pump 21 sucks air to the sealing groove 18, the air pressure in the sealing groove 18 is reduced, so that the sealing sliding block 19 is pulled to slide under the action of the air pressure and overcomes the elastic force of the fixed spring 20; for the fixed spring 20 with a small elastic coefficient, the sealing sliding block 19 is pulled to slide a large distance and is separated from the inner wall of the communicating pipe 3, so that the pushing effect of the spiral conveying blade 11 on the raw materials is reduced, the conveying speed of the raw materials is reduced, the output speeds of the two kinds of raw materials are different, the mixing ratio of the two kinds of raw materials is adjusted, the mixing effect of the two kinds of raw materials is improved, and the grouting effect is improved.
