[0037] The raw material stirring device for bridge channel grouting comprises a base 1, a stirring barrel 3, a support plate 10, a stirring assembly 4 and a vibrating rod 11;

[0038] The base 1 is connected to a rotating disk 2 and a rotating plate 12 for rotation. A mixing barrel 3 can be placed on the rotating disk 2 to mix the raw materials. A support plate 10 is fixedly connected to the top of the rotating plate 12. The support plate 10 can be driven to rotate by the rotating plate 12. A lifting groove 1001 is provided on the rotating plate 10. The lifting groove 1001 is vertical and has a lifting plate 5 inside. The lifting plate 5 passes through the lifting groove 1001 horizontally, and two slide bars 8 and a threaded rod 9 are provided inside the lifting groove 1001. The lifting plate 5 has sliding holes and threaded holes. The slide bars 8 and the threaded rod 9 The sliding hole and the threaded hole are respectively passed through, and the rotation of the threaded rod 9 can drive the lifting plate 5 to move up and down outside the sliding rod 8, and a lifting motor 15 is fixedly connected to one side of the support plate 10, and a transmission gear 14 is fixedly connected to the output shaft of the lifting motor 15 and the lower end of the threaded rod 9. The two transmission gears 14 are meshed, and the lifting motor 15 can drive the transmission gear 14 to rotate, thereby driving the threaded rod 9 to rotate, so that the lifting plate 5 is lowered or raised, thereby driving the stirring assembly 4 and the lower end of the vibration rod 11 to enter or leave the stirring barrel 3.

[0039] In addition, in order to increase the stability of the lifting plate 5;

[0040] A threaded barrel 13 is provided at the bottom of the lifting plate 5, and a support rod is fixedly connected to the threaded barrel 13. The upper end of the support rod is fixed to the bottom of the lifting plate 5, and the threaded rod 9 is threadedly connected to the threaded barrel 13. The threaded barrel 13 can improve the stability of the lifting plate 5 on the threaded rod 9.

[0041] The stirring assembly 4 includes a stirring shaft, a plurality of first stirring rods 401 and two second stirring rods 402, each of the first stirring rods 401 is arranged at intervals along the axis of the stirring shaft, each of the second stirring rods 402 is fixedly connected to one end of each of the first stirring rods 401, a through hole is opened at one end of the lifting plate 5, a fixed cylinder is fixedly connected to the through hole, the stirring shaft passes through the fixed cylinder and is rotatably connected to the fixed cylinder, so that the stirring shaft rotates smoothly on the lifting plate 5, and a stirring motor 7 is installed on the lifting plate 5, and a pulley is provided on the upper end of the stirring shaft and the output shaft of the stirring motor 7. A transmission belt is provided in the mixing barrel 3, and the mixing shaft can be driven to rotate through the mixing motor 7 and the transmission belt, thereby driving the first mixing rod 401 and the second mixing rod 402 to move, and the raw materials inside the mixing barrel 3 are stirred. During stirring, the supporting plate 10 can be driven to rotate slightly through the rotating plate 12, so that the lifting plate 5 is deflected, and the stirring component 4 is driven to approach the barrel wall of the mixing barrel 3. At this time, the mixing barrel 3 can also be driven to rotate through the rotating disk 2, so that the raw materials close to the barrel wall of the mixing barrel 3 are stirred by the stirring component 4, thereby enhancing the stirring and mixing effect of the device on the raw materials.

[0042] Two vibrating rods 11 are provided and are installed at intervals at the bottom end of the lifting plate 5 along the length direction of the lifting plate 5. After the stirring assembly 4 fully stirs and mixes the raw materials, the stirring assembly 4 is lifted by the lifting plate 5, and then the support plate 10 is rotated 180°, and the vibrating rod 11 comes to the top of the mixing barrel 3. Then, the lifting plate 5 is lowered to allow the lower end of the vibrating rod 11 to be inserted into the interior of the mixing barrel 3, and the slurry after stirring and mixing is vibrated to remove the bubbles inside.

[0043] The working principle of the raw material stirring device for bridge channel grouting is as follows: when in use, the stirring barrel 3 is first placed on the rotating disk 2, and then the raw materials are added to the stirring barrel 3, and the transmission gear 14 is driven to rotate by the lifting motor 15, thereby driving the threaded rod 9 to rotate, so that the lifting plate 5 descends outside the sliding rod 8, driving the stirring assembly 4 to descend, and the first stirring rod 401 and the second stirring rod 402 enter the interior of the stirring barrel 3.

At this time, the stirring barrel 3 can also be driven to rotate by the rotating disk 2, so that the stirring component 4 can stir the raw materials close to the barrel wall of the stirring barrel 3, thereby enhancing the stirring and mixing effect of the device on the raw materials;

[0045] After the stirring is completed, the transmission gear 14 is driven to rotate in the opposite direction by the lifting motor 15, thereby driving the threaded rod 9 to rotate in the opposite direction, so that the lifting plate 5 rises outside the sliding rod 8, driving the stirring assembly 4 to leave the stirring barrel 3, and then the supporting plate 10 is driven to rotate 180° by the rotating plate 12, so that the vibrating rod 11 comes to the top of the stirring barrel 3, and then the lifting plate 5 is lowered, so that the lower end of the vibrating rod 11 is inserted into the slurry in the stirring barrel 3, and the vibrating rod 11 works to vibrate the slurry, thereby expelling the bubbles inside it and improving the slurry quality;

[0046] Finally, the vibrating rod 11 is driven to leave the mixing barrel 3 by the lifting plate 5, and the slurry stirred and mixed inside the mixing barrel 3 can be discharged for use. When the next slurry configuration is required, the mixing barrel 3 containing the mixed slurry can be removed, and then a new mixing barrel 3 can be placed for the next slurry configuration, thereby improving the slurry configuration efficiency.
