By setting the assembly plate 14, the grouting pump can be conveniently assembled on the mobile base plate 11. A stirring mechanism 5 is provided on the slurry making tank 12, and a vibration mechanism 7 is provided between the mobile base plate 11 and the slurry making tank 12.

One end of the lifting sleeve 52 is rotatably installed on the rotating ring 65. By driving the reciprocating screw 57 to rotate, the reciprocating screw 57 can make the movable block 63 move in the thread groove of the reciprocating screw 57. The movable block 63 moves back and forth up and down in the groove (there are two mirror-image thread grooves on the reciprocating screw 57. When the movable block 63 rises along one thread groove to the end of the thread groove, the movable block 63 enters the end of the other thread groove. As the reciprocating screw 57 rotates, the movable block 63 rotates and completely enters the other thread groove, and descends vertically along the other thread groove to achieve reciprocating lifting). The movable block 63 can make the sliding seat 59 reciprocate and rise and fall through the connecting shaft 62. The sliding seat 59 can make the lifting sleeve 52 and the stirring blade 53 reciprocate and rise and fall on the stirring rod 51 through the connecting frame 64 and the rotating ring 65, thereby stirring the raw materials in the pulping tank 12 in all directions.

[0028] A plurality of slots 54 are provided on the stirring rod 51, and a plurality of blocks 55 are fixedly provided on the inner wall of the lifting sleeve 52. The blocks 55 are slidably provided in the slots 54.

[0029] Guide grooves 6 are provided on both sides of the device box 56, and guide blocks 61 are fixedly provided on both sides of the sliding seat 59. The guide block 61 is slidably set at one end of the guide groove 6.

A transmission belt 68 is installed between the two toothed pulleys 67. By starting the servo motor 66, the driving shaft of the servo motor 66 can rotate the stirring rod 51. By setting the toothed pulley 67 and the transmission belt 68, the stirring rod 51 can make the reciprocating screw 57 rotate synchronously through the toothed pulley 67 and the transmission belt 68.

[0031] The vibration mechanism 7 includes a rotating shaft 71, which is rotatably mounted on the movable base plate 11. A plurality of eccentric wheels 72 are fixedly provided on the rotating shaft 71. A plurality of push plates 73 are fixedly provided on the outer wall of the pulping tank 12. The eccentric wheels 72 correspond horizontally to the push plates 73. By driving the rotating shaft 71 to rotate, the rotating shaft 71 can rotate the eccentric wheels 72. When the eccentric wheels 72 come into contact with the push plates 73, the pulping tank 12 can be pushed to move horizontally through the push plates 73. A number of fixed plates 74 are fixedly provided on the upper surface of the movable base plate 11, a number of fixed seats 75 are fixedly provided on the outer wall of the pulping tank 12, and a spring rod 76 is fixedly provided between the fixed plate 74 and the fixed seat 75. By setting the spring rod 76, when the pulping tank 12 is pushed to move horizontally toward one side of the spring rod 76, the spring rod 76 is squeezed and contracted. When the pushing of the pulping tank 12 stops, the extension and reset of the spring rod 76 can make the pulping tank 12 move horizontally in the opposite direction and reset, thereby making the pulping tank 12 and the raw materials inside it vibrate.

[0032] A plurality of slide grooves 77 are provided on the upper surface of the movable base plate 11, and a plurality of bases 79 are fixedly provided at the bottom end of the pulping tank 12. A slider 78 is fixedly provided at one end of the base 79, and the slider 78 is slidably provided at one end of the slide groove 77. By setting the slide groove 77 and the slider 78, the slider 78 can slide horizontally along the inner wall of the slide groove 77, so that the pulping tank 12 can be kept moving in the horizontal direction through the base 79, and the pulping tank 12 can be supported by the base 79 at the same time.

[0033] The open end of the pulping tank 12 is rotatably installed with a No. 1 transmission shaft 8, and the top of the movable base plate 11 is rotatably installed with a No. 2 transmission shaft 81. One end of the No. 1 transmission shaft 8 is slidably arranged in the inner cavity of one end of the No. 2 transmission shaft 81, and the other end of the No. 1 transmission shaft 8 and the end of the stirring rod 51 close to the servo motor 66 are fixedly provided with a No. 1 bevel gear 82, and the two No. 1 bevel gears 82 are meshed and connected. The other end of the No. 2 transmission shaft 81 and one end of the rotating shaft 71 are fixedly provided with a No. 2 bevel gear 83, and the two No. 2 bevel gears 83 are meshed and connected. When the stirring rod 51 rotates, the stirring rod 51 can rotate the No. 1 transmission shaft 8 through the two No. 1 bevel gears 82, and the No. 1 transmission shaft 8 can make the No. 2 transmission shaft 81 rotate synchronously, and the No. 2 transmission shaft 81 can make the rotating shaft 71 rotate through the two No. 1 bevel gears 82. At the same time, when the pulping tank 12 vibrates, one end of the No. 1 transmission shaft 8 can slide horizontally in the No. 2 transmission shaft 81 to ensure power transmission.

[0034] Working principle: During the municipal pipeline grouting operation, before the grouting operation, the raw materials and water for preparing the cement slurry are first added to the slurry tank 12, and then the servo motor 66 is started. The drive shaft of the servo motor 66 rotates the stirring rod 51, and the stirring rod 51 rotates the lifting sleeve 52 and the stirring blade 53 through the block 55. The stirring blade 53 stirs the raw materials and water in the slurry tank 12 at a high speed; At the same time, the stirring rod 51 rotates the reciprocating screw 57 synchronously through the two toothed pulleys 67 and the transmission toothed belt 68. The reciprocating screw 57 causes the movable block 63 to move up and down reciprocatingly in the threaded groove of the reciprocating screw 57. The movable block 63 causes the sliding seat 59 to move up and down reciprocatingly through the connecting shaft 62. The sliding seat 59 causes the lifting sleeve 52 and the stirring blade 53 to move up and down reciprocatingly on the stirring rod 51 through the connecting frame 64 and the rotating ring 65. The stirring blade 53 stirs the raw materials and water in the slurry tank 12 in an all-round manner during the process of rotating and synchronously reciprocating and lifting, thereby improving the stirring effect of the raw materials and water, and further improving the preparation effect and efficiency of the cement slurry. At the same time, the stirring rod 51 rotates the No. 1 transmission shaft 8 through the two No. 1 bevel gears 82, and the No. 1 transmission shaft 8 rotates the No. 2 transmission shaft 81 synchronously. The No. 2 transmission shaft 81 rotates the rotating shaft 71 through the two No. 1 bevel gears 82, and the rotating shaft 71 rotates the eccentric wheel 72. When the eccentric wheel 72 contacts the push plate 73, the eccentric wheel 72 pushes the slurry making tank 12 to move horizontally through the push plate 73, and the slurry making tank 12 contracts the spring rod 76 through the fixed seat 75. When the eccentric wheel 72 is staggered with the push plate 73, the spring rod 76 extends and resets, causing the slurry making tank 12 to move in the opposite direction and reset. As the eccentric wheel 72 rotates, the slurry making tank 12 and the raw materials and water in the slurry making tank 12 vibrate, further improving the preparation effect of the cement slurry.
