[0035] like Figure 1-11 As shown, the intelligent control component 8 includes a PLC control module 38, which is fixedly connected to the top of the main plate 1. A battery 39 is also fixedly connected to the top of the main plate 1. The horizontal adjustment component 9 includes a connecting plate 40, which is arranged below the main plate 1. Short columns 41 are evenly fixed at the four corners of the top of the connecting plate 40. The top of the short column 41 is fixedly connected to a screw 42, and a lifting block 43 is threadedly connected to the screw 42.

[0036] When in use, firstly, the PLC control module 38 is programmed with data. During use, the PLC control module 38 controls the grouting pump 31 to extract water and raw materials from the storage box 1 28 and the storage box 2 29 according to the predetermined programming. The two groups of grouting pumps 31 work asynchronously, that is, water or raw materials enter the mixing barrel 15 from the conduit 30 in batches. When the water or raw materials enter the mixing barrel 15, their own gravity forces the mixing barrel 15 to press the spring 10 downward. At this time, the slide column 14 slides along the socket 13 to play a role of limiting and stabilizing. At this time, the distance sensor 27 measures the distance data between the bottom of the mixing barrel 15 and the bottom of the main barrel 3 and transmits it to the mixing barrel 15. PLC control module 38, PLC control module 38 calculates whether the proportioning is completed according to the pre-compiled distance and weight comparison relationship, and starts motor 23 after the proportioning is completed. Motor 23 drives bevel gear three 24 to rotate to generate a force and drives bevel gear one 21 and bevel gear two 22 to rotate at the same time. Bevel gear one 21 drives shaft 20 to rotate in one direction, shaft 20 drives stirring rod 25 to rotate, bevel gear two 22 drives rotating sleeve 19 to rotate in another direction, rotating sleeve 19 drives stirring frame 49 to rotate, thereby playing the function of two-way stirring. After the stirring is completed, discharge pump 34 is started, and the mixed materials are discharged from The hose 33 is discharged through the discharge cone head 35. Because the discharge cone head 35 is connected to the end of the hose 33 by a thread, the discharge cone head 35 of different sizes can be replaced according to actual needs. After use, the discharge cone head 35 is placed through the support ring 36. When leveling is required, first start the electric telescopic rod 47 to roughly level it, then rotate and remove the screw 45. At this time, rotate the lifting block 43 so that the lifting block 43 rises with the screw 42 to play a role of fine-tuning. Repeat the steps of rotating the first group of lifting blocks 43 for the other groups of lifting blocks 43 to rotate to the appropriate position. During the leveling process, you need to observe the level at all times The instrument 46 is convenient for precise leveling. After the leveling is completed, the lifting block 43 and the connecting plate 40 can be fixed again with the screws 45. In summary, the device can achieve the functions of precise automatic weighing and material proportioning by combining the distance measuring sensor 27, the PLC control module 38, the grouting pump 31 and the discharge pump 34 through electrical connection, which can free up manpower and improve accuracy. By setting up a two-way stirring component 5, the material entering the mixing barrel 15 can be fully stirred in both directions. By setting up a horizontal adjustment component 9, the entire device in the mine can be horizontally leveled, further improving the uniformity of mixing.
