[0021] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0022] according to Figure 1-5 As shown, this embodiment proposes a solution: a dry-mixed mortar proportioning and mixing device, including a base 1, a mixing cylinder 2 disposed inside the base 1, side plates 3 fixedly installed on the left and right sides of the base 1 and fitted to the mixing cylinder 2, a stirring mechanism 4 for stirring inside the mixing cylinder 2 fixedly installed on the surface of the left side plate 3, a discharge pipe 5 connected to the mixing cylinder 2 fixedly installed on the surface of the right side plate 3, three discharge ports 6 fixedly installed on the top of the mixing cylinder 2, a lifting plate 7 slidably connected to the inner sidewalls of the two side plates 3 near the top, three proportioning boxes 8 engaged inside the lifting plate 7, an annular locking block 9 fixedly installed near the center of the surface of the proportioning box 8, two positioning holes opened on the left side of the annular locking block 9, a locking groove adapted to the annular locking block 9 opened on the top of the lifting plate 7, a driving component disposed inside the side plate 3 for adjusting the height of the lifting plate 7, and a positioning component disposed inside the lifting plate 7 for positioning the annular locking block 9.

[0023] In this embodiment, the proportioning box 8 is engaged with the groove on the top of the lifting plate 7 by the annular locking block 9 on its surface, and the annular locking block 9 is positioned by the positioning component, so that the proportioning box 8 remains stable during the lifting process, ensuring that the raw materials can accurately enter the mixing cylinder 2, thereby improving the stability and efficiency of the proportioning. The dry mortar raw materials are placed inside the proportioning box 8 and proportioned by the proportioning box 8, which improves the proportioning efficiency and accuracy. The lifting plate 7 is driven by the drive component to descend to a suitable height, so that the raw materials fall into the mixing cylinder 2 through the discharge port 6 for subsequent mixing. Compared with the traditional method of pouring in batches and then stirring, this structure can stir in time after the raw materials enter, shortening the overall mixing time, improving the mixing efficiency, and enhancing the practicality of the device.

[0024] A feed pipe is fixedly installed on the top of the mixing tank 8, and a discharge pipe is fixedly installed on the bottom of the mixing tank 8. An observation window 10 is opened on the left side of the mixing tank 8. An annular baffle that matches the discharge port 6 is fixedly installed on the bottom of the mixing tank 8. The raw materials enter through the feed pipe at the top of the mixing tank 8. The staff can observe the amount of raw materials through the observation window 10 on the left side. The raw materials are discharged through the discharge pipe at the bottom. The annular baffle at the bottom matches the discharge port 6 to ensure that the raw materials fall accurately.

[0025] The drive assembly includes two lifting blocks 11. A lifting groove is provided on the inner side of the side plate 3 for the lifting blocks 11 to slide up and down. The side wall of the lifting block 11 is fixedly connected to the surface of the lifting plate 7. A first lead screw 12 is threaded through the inner side of the front lifting block 11 and connected to it. A drive motor 13 is fixedly installed on the top of the front lifting block 11 to drive the first lead screw 12 to rotate. A sliding rod is threaded through the inner side of the rear lifting block 11 and connected to it. The top and bottom ends of the first lead screw 12 are fixedly connected to the inner side wall of the adjacent lifting groove. When the drive motor 13 starts, it drives the first lead screw 12 to rotate. The front lifting block 11, threaded to the first lead screw 12, slides up and down in the lifting groove on the inner side of the side plate 3. The rear lifting block 11 slides synchronously along the sliding rod, thereby driving the lifting plate 7 to rise and fall. This allows the mixing box 8 to be quickly lowered to the appropriate position, saving time and manpower and improving work efficiency.

[0026] A driven rod 14 is slidably connected to the inner side of the side plate 3. The right end of the driven rod 14 passes through the inner side of the side plate 3 and is fixedly installed with a drive plate 15. A sealing plate 16 adapted to the discharge port 6 is fixedly installed on the left side of the drive plate 15. A second lead screw 17 is threadedly connected to the inner side of the driven rod 14. The left end of the second lead screw 17 is rotatably connected to the inner wall of the side plate 3. A rotating gear 18 is fixedly installed on the outer surface of the second lead screw 17. A toothed block 19 is meshed on the rear side of the rotating gear 18. The front side of the toothed block 19 is fixedly connected to the surface of the adjacent lifting block 11. When the lifting block 11 slides downward, the toothed block 19 on its surface drives the rotating gear 18. Rotating the screw 17 causes the second lead screw to rotate. The driven rod 14, which is threadedly connected to the second lead screw 17, drives the drive plate 15 to move to the right. The driven rod 14 slides synchronously. The sealing plate 16 on the left side of the drive plate 15 disengages from the insertion groove inside the discharge port 6, facilitating the discharge of materials from the mixing tank 8. No additional power is needed to control the opening and closing of the discharge port 6. This achieves linkage with the lifting plate 7. The sealing plate 16 automatically opens when discharging materials and automatically seals when not discharging materials. This avoids the cumbersome steps of opening and closing the discharge port in traditional batch operations, while preventing the raw materials in the mixing drum 2 from overflowing, thus improving the convenience of operation and the utilization rate of raw materials.

[0027] The inner side of the discharge port 6 is provided with a plug groove that matches the sealing plate 16. The inner side of the rear side plate 3 is provided with a rotating port that allows the rotating gear 18 to rotate. The rear side of the rear side plate 3 is provided with a connecting groove that allows the tooth block 19 to slide up and down. The rotating gear 18 and the tooth block 19 can move through the connecting groove and the rotating port.

[0028] The positioning assembly includes a threaded rod 20, with its left and right ends rotatably connected to the inner wall of the lifting plate 7. A movable plate 21, which is slidably connected to the inner wall of the lifting plate 7, is threaded onto the surface of the threaded rod 20. A positioning rod 22, which is adapted to the positioning hole, is fixedly installed on the right side of the movable plate 21 near the front and rear sides. A knob for driving the threaded rod 20 to rotate is rotatably connected to the left side of the lifting plate 7. A connecting hole for the positioning rod 22 to pass through is opened on the inner side of the lifting plate 7. Rotating the knob on the left side of the lifting plate 7 drives the threaded rod 20 in the positioning assembly to rotate, causing the movable plate 21 to slide on the inner wall of the lifting plate 7. The positioning rod 22 on the right side of the movable plate 21 is inserted into the positioning hole on the left side of the annular locking block 9, thus completing the positioning of the mixing box 8.

[0029] The above embodiment discloses a dry-mixed mortar proportioning and mixing device, wherein the proportioning box 8 is engaged in the slot at the top of the lifting plate 7 by the annular locking block 9 on its surface. Rotating the knob on the left side of the lifting plate 7 drives the threaded rod 20 in the positioning assembly to rotate, causing the moving plate 21 to slide on the inner wall of the lifting plate 7. The positioning rod 22 on the right side of the moving plate 21 is inserted into the positioning hole on the left side of the annular locking block 9, completing the positioning of the proportioning box 8. The raw material enters through the feed pipe at the top of the proportioning box 8. The operator can observe the amount of raw material through the observation window 10 on the left side. The raw material is discharged through the discharge pipe at the bottom. The annular baffle at the bottom is adapted to the discharge port 6 to ensure that the raw material falls accurately. The drive motor 13 is started, driving the first lead screw 12 to rotate. The front lifting block 11, which is threadedly connected to the first lead screw 12, slides up and down in the lifting groove on the inner side of the side plate 3. The rear lifting block 11 slides along the sliding rod. Synchronous sliding causes the lifting plate 7 to rise and fall, quickly lowering the mixing tank 8 to the appropriate position, saving time and manpower and improving work efficiency. At the same time, when the lifting block 11 slides down, the toothed block 19 on its surface drives the rotating gear 18 to rotate, causing the second lead screw 17 to rotate. The rear driven rod 14, which is threadedly connected to the second lead screw 17, drives the drive plate 15 to move to the right. The front driven rod 14 slides synchronously, and the sealing plate 16 on the left side of the drive plate 15 disengages from the insertion groove inside the discharge port 6, facilitating the discharge of the mixing tank 8. No additional power is needed to control the opening and closing of the discharge port 6, realizing linkage with the lifting plate 7. When discharging, the sealing plate 16 automatically opens and automatically seals when not discharging, avoiding the cumbersome steps of opening and closing the discharge port in traditional batch operations. At the same time, it prevents the raw materials in the mixing drum 2 from overflowing, improving the convenience of operation and the utilization rate of raw materials.
