DETAILED DESCRIPTION
[0031] like Figures 1-8 As shown, an intelligent synchronous mortar grouting equipment includes a dry powder bin 3, a mixing tank 12 and a slurry storage tank 13.
[0032] Two dry powder silo hoisting hooks 2 are symmetrically fixedly mounted on either side of the dry powder silo 3. A horizontal screw conveyor 4 is installed below the dry powder silo 3 and communicates with the interior thereof. The horizontal screw conveyor 4 and the dry powder silo 3 are integrally designed to ensure timely material delivery. The horizontal screw conveyor 4 is connected to the mixing tank feed port 11 mounted at one end of the mixing tank 12 via an angled screw conveyor 7.
[0033] Specifically: A horizontal screw conveyor motor reducer 1 for driving the internal spiral rotation is installed at one external end of the horizontal screw conveyor 4, and a horizontal screw conveyor discharge port 5 is provided at the other end of the horizontal screw conveyor 4. An inclined screw conveyor feed port 6 is provided on the lower side of the inclined screw conveyor 7, and the inclined screw conveyor feed port 6 and the horizontal screw conveyor discharge port 5 are disconnectably connected, so as to facilitate the quick replacement of the dry powder bin 3 by hoisting through the dry powder bin hoisting hook 2, thereby ensuring the timeliness of material supply. An inclined screw conveyor motor reducer 9 for driving the internal spiral rotation is installed on the upper end of the inclined screw conveyor 7, and an inclined screw conveyor discharge port 10 is provided on the upper side of the inclined screw conveyor 7, and the inclined screw conveyor discharge port 10 is directly opposite the mixing tank feed port 11.
[0034] During operation, the horizontal screw conveyor 4 is driven by the horizontal screw conveyor motor reducer 1 to drive the internal screw of the horizontal screw conveyor 4 to carry the material to the horizontal screw conveyor discharge port 5 and convey the material to the inclined screw conveyor feed port 6. After the material reaches the horizontal screw conveyor discharge port 5 and is conveyed to the inclined screw conveyor feed port 6, the inclined screw conveyor motor reducer 9 drives the internal screw of the inclined screw conveyor 7 to convey the material from the inclined screw conveyor discharge port 10 to the mixing tank feed port 11. After the material enters the mixing tank 12, it is slurried and stirred.
[0035] The interior of the stirring tank 12 is relatively rotatably installed with a first stirring tank stirring shaft 28 and a second stirring tank stirring shaft 29. The end of the stirring tank 12 away from the stirring tank feed port 11 is installed with a first stirring tank drive motor 25 and a second stirring tank drive motor 26 for driving the first stirring tank stirring shaft 28 and the second stirring tank stirring shaft 29 to rotate respectively. In addition, a grease pump 27 is installed on the outside of the stirring tank 12 between the first stirring tank drive motor 25 and the second stirring tank drive motor 26.
[0036] During the slurrying and stirring process, the first stirring tank driving motor 25 drives the first stirring tank stirring shaft 28 to rotate clockwise, and the second stirring tank driving motor 26 drives the second stirring tank stirring shaft 29 to rotate counterclockwise, so that the material circulates in the stirring tank 12 to achieve a uniform slurrying effect.
[0037] The slurry storage tank 13 is disposed below the mixing tank 12, and the bottom ends of the mixing tank 12 are connected to the slurry storage tank 13 via a first mixing tank discharge butterfly valve 8 and a second mixing tank discharge butterfly valve 16, respectively. The two ends of the slurry storage tank 13 are respectively provided with a first slurry storage tank slurry outlet 93 and a second slurry storage tank slurry outlet 100. A mortar pump rack 18 is disposed below the slurry storage tank 13, and a first mortar delivery pump 20 and a second mortar delivery pump 21 for delivering slurry are mounted on the base of the mortar pump rack 18.

[0039] After the slurry is prepared in the mixing tank 12, the prepared slurry is transported to the slurry storage tank 13 for storage by controlling the first mixing tank discharge butterfly valve 8 and the second mixing tank discharge butterfly valve 16. The first slurry storage tank slurry outlet 93 and the second slurry storage tank slurry outlet 100 are respectively connected to the first mortar delivery pump slurry inlet 17 and the second mortar delivery pump slurry inlet 22 by bolts, so that the slurry in the slurry storage tank 13 can be injected into the working point from the first mortar delivery pump slurry outlet 14 and the second mortar delivery pump slurry outlet 23 after the first mortar delivery pump 20 and the second mortar delivery pump 21 work.
[0040] The mixing tank 12 is fixedly mounted on a mixing tank frame 19, and a load cell 15 is mounted above the mixing tank frame 19 for fixedly supporting the mixing tank 12. A mixing tank water supply valve and a flow meter 24 are mounted on the outer side of the slurry storage tank 13, which are connected to the mixing tank 12. This allows the mixing tank water supply valve and the flow meter 24 to supply water to the mixing tank normally without affecting the weighing of the mixing tank by the load cell 15.
[0041] A reducer fixing plate 91 is fixedly mounted on one end of the upper portion of the slurry storage tank 13. A slurry storage tank scraper motor reducer 90 is fixedly mounted on the outer side of the reducer fixing plate 91. A reducer shaft 94 is mounted on the output end of the slurry storage tank scraper motor reducer 90. The reducer shaft 91 is connected to a lead screw 97 via a coupling 95. A fixed bearing seat 96 and a support bearing seat 98 are mounted on the upper portion of the slurry storage tank 13. The lead screw 97 is rotatably mounted between the fixed bearing seat 96 and the support bearing seat 98. A scraper assembly 92 is threadedly mounted on the lead screw 97. The slurry storage tank scraper motor reducer 90, fixed to the reducer fixing plate 91, drives the lead screw 97 via the reducer shaft 94 and the coupling 95 to achieve linear reciprocating motion of the scraper assembly 92, thereby achieving the purpose of cleaning the slurry inside the slurry storage tank 13 and eliminating residue.
[0042] The scraper assembly 92 includes a slide 120, with channel steel wheels 125 rotatably mounted on both sides of the slide 120. The wheel seats of each channel steel wheel 125 are fixedly connected to the slide 120 via a channel steel wheel fixing nut 126. The two channel steel wheels 125 are adapted to the channel steels 99 on both sides of the slurry storage tank 13. The channel steel wheels 125 can provide support and guidance inside the channel steels 99 on both sides of the slurry storage tank 13. A screw nut 123 is fixedly mounted in the middle of the upper portion of the slide 120 via a screw nut fixing bolt 124. The screw nut 123 is adapted to the screw 97 and is sleeved on the outside of the screw 97. When the screw 97 rotates, the scraper assembly 92 is driven to perform linear motion. A scraper 121 is fixedly provided below the slide 120 via scraper fixing bolts 122 , and a scraper edge rubber strip 127 is fixedly installed on the outer periphery of the scraper 121 via scraper edge rubber strip fixing bolts 128 .
[0043] The working process of this utility model is as follows:
[0044] After setting the slurry ratio, water is quantitatively added to the mixing tank 12 through the mixing tank water valve and flow meter 24. After the water is added, the material in the dry powder bin 3 is driven by the horizontal screw conveyor motor reducer 1 to drive the internal screw of the horizontal screw conveyor 4 to the horizontal screw conveyor discharge port 5 and convey the material to the inclined screw conveyor feed port 6. The inclined screw conveyor motor reducer 9 then drives the internal screw of the inclined screw conveyor 7 to convey the material from the inclined screw conveyor discharge port 10 to the mixing tank feed port 11. After the material enters the mixing tank 12, it is slurried and stirred. The required material weight is measured by the weighing sensor 15. When the weight reaches the set target value, the horizontal screw conveyor 4 and the inclined screw conveyor 7 stop conveying the material. The mixing tank 12 is started for mixing and slurrying. After the slurrying is completed, it is discharged into the slurry storage tank 13 through the first mixing tank discharge butterfly valve 8 and the second mixing tank discharge butterfly valve 16. The slurry is then discharged by the first mortar delivery pump 20 and the second mortar delivery pump 21.
