The number of driven pulleys 8 is two and the two driven pulleys 8 are respectively arranged on both sides of the driving pulley 7. The two driven pulleys 8 are rotatably connected to the two sides inside the protective shell 10. The outsides of the two driven pulleys 8 are both transmission-connected with belts 9 and are both transmission-connected to the driving pulley 7 through the belts 9. The active end of the driving assembly is provided with a stirring and feeding mechanism that can stir the mortar in the mixing barrel 2. The stirring and feeding mechanism includes a first spiral rotating rod 11, a second spiral rotating rod 12, a fixing frame 13 and a stirring plate 14. The first spiral rotating rod 11 is fixedly connected to the bottom end of the driving pulley 7, and the fixing frame 13 is fixedly connected to the first spiral rotating rod 11. A stirring plate 14 is fixedly connected to the side and outer surface of the rotating rod 11, there are two second spiral rotating rods 12, and the two second spiral rotating rods 12 are respectively fixedly connected to the bottom ends of the two driven pulleys 8, the first spiral rotating rod 11 and the second spiral rotating rod 12 are both penetrated into the interior of the mixing barrel 2, there are three conical feeding tubes 5, and the three conical feeding tubes 5 are respectively vertically corresponding to the first spiral rotating rod 11 and the two second spiral rotating rods 12, the bottoms of the first spiral rotating rod 11 and the two second spiral rotating rods 12 are respectively inserted into the interiors of the three conical feeding tubes 5, when the driving motor 6 drives the active pulley 7 and the first spiral rotating rod 11 to rotate clockwise, the driven pulleys 8 and the first spiral rotating rod 12 on both sides can be driven by the belt 9. The two spiral rotating rods 12 rotate clockwise synchronously, so that the stirring plate 14 can stir the mortar in the mixing barrel 2, and the first spiral rotating rod 11 and the second spiral rotating rod 12 can transfer the mortar at the bottom of the mixing barrel 2 upward, so that the upper and lower parts of the mortar are mixed more evenly; when the driving motor 6 drives the active pulley 7 and the first spiral rotating rod 11 to rotate counterclockwise, the driven pulleys 8 and the second spiral rotating rod 12 on both sides can be driven by the belt 9 to rotate counterclockwise synchronously, so that the first spiral rotating rod 11 and the second spiral rotating rod 12 can transfer the mortar in the mixing barrel 2 from top to bottom, and when the electromagnetic valve 18 at the bottom of the conical discharge pipe 5 is opened, the mortar can flow into the quantitative barrel 15 faster, thereby improving the construction efficiency;

[0023] The lower surface of the mixing barrel 2 is fixedly connected with a conical discharge pipe 5, and the bottom end of the conical discharge pipe 5 is connected with a quantitative mechanism for quantitatively storing mortar through a thread. The quantitative mechanism includes a quantitative barrel 15, a distance sensor 16 and a discharge pipe 17. The center of the circle on the upper surface of the quantitative barrel 15 is connected to the bottom of the conical discharge pipe 5 through a thread. The upper surface of the quantitative barrel 15 is provided with a through hole to ensure that the internal air pressure is consistent with the external pressure, and a scale line is provided on the side, so that the amount of mortar in the quantitative barrel 15 can be easily observed from the outside. The distance sensor 16 is fixedly installed on the quantitative barrel 1 5 and the sensing direction vertically corresponds to the inner bottom wall of the quantitative barrel 15. When the mortar enters the quantitative barrel 15, since the electromagnetic valve 18 at the bottom is in a closed state, the original air inside the quantitative barrel 15 will be discharged from the through hole at the top to ensure that the mortar can fall normally. The distance sensor 16 can detect the distance between itself and the mortar surface in the quantitative barrel 15 in real time, so that the content of the mortar stored in the quantitative barrel 15 can be known in real time. When the required content of mortar is reached, the electromagnetic valve 18 at the bottom of the conical discharge pipe 5 can be controlled to close.

[0024] The discharge pipe 17 is fixedly installed at the bottom of the quantitative barrel 15. The number of quantitative mechanisms is three and the three quantitative mechanisms are respectively connected to the three conical discharge pipes 5. The bottoms of the conical discharge pipe 5 and the discharge pipe 17 are fixedly installed with electromagnetic valves 18 that can control their on and off. The outside of the quantitative mechanism is provided with a vibration mechanism that can vibrate it and the two ends of the vibration mechanism are sleeved on the outside of the support rod 3. The vibration mechanism includes an outer frame 19, an inner frame 20, a spring 21 and a vibration motor 22, a drive motor 6, a distance sensor 16, and an electromagnetic valve 1 8 and the vibration motor 22 are electrically connected to the external control unit through wires, both sides of the outer frame 19 are fixedly connected with sleeves 23, and the sleeves 23 on both sides are respectively sleeved on the outside of the support rods 3 on both sides, and the side threads of the sleeves 23 are threaded with locking bolts, and one end of the locking bolt passes through the sleeves 23 and is pressed against the side of the support rod 3, so that the outer frame 19 can be fixed at a specific position on the support rod 3. The number of springs 21 is several, and the springs 21 are fixedly connected to the inner side wall of the outer frame 19. The inner frame 20 is arranged inside the outer frame 19 and is connected to the spring The end of the spring 21 away from the outer frame 19 is fixedly connected, the inner frame 20 is sleeved on the outside of the three quantitative barrels 15, the vibration motor 22 is fixedly installed on the inner side wall of the outer frame 19 and the output end is fixedly connected to the inner frame 20. After the outer frame 19 is fixed, it is connected to the inner frame 20 only through the spring 21, so the inner frame 20 will shake when subjected to external force, and the movable end of the vibration motor 22 is connected to the inner frame 20, so driving the vibration motor 22 to run can cause high-frequency vibration to the inner frame 20. The inner frame 20 is sleeved on the three quantitative barrels 15. The outside of the measuring barrel 15 can therefore exert a high-frequency vibration effect on the quantitative barrel 15, so that the mortar in the quantitative barrel 15 can be subjected to high-frequency vibration and become more solid, making the data detected by the distance sensor 16 more accurate, thereby improving the accuracy of the mortar quantification. When the mortar reaches the specified amount, the electromagnetic valve 18 at the bottom of the conical discharge pipe 5 is closed, and the electromagnetic valve 18 at the bottom of the quantitative barrel 15 is opened, thereby discharging the mortar into the container below, and the three quantitative barrels 15 can simultaneously discharge three groups of mortars in a quantitative manner, greatly speeding up the construction efficiency.

[0025] In summary, the use steps of the quantitative feeding device for anti-cracking mortar with a stirring structure are as follows:

[0026] 1. When it is necessary to take out the mortar quantitatively, the driving motor 6 is controlled to operate so that the driving pulley 7 and the driven pulley 8 rotate counterclockwise synchronously, and the container containing the quantitative mortar is placed below the corresponding quantitative barrel 15 on the base 1, and then the electromagnetic valve 18 at the bottom of the corresponding conical discharge pipe 5 is opened as needed to allow the mortar to flow into the quantitative barrel 15 below;

[0027] 2. At the same time, the vibration motor 22 runs to vibrate the inner frame 20 and the quantitative barrel 15 at high frequency to ensure that the mortar in the quantitative barrel 15 is vibrated and compacted. Then, after the distance sensor 16 detects that the distance from the upper surface of the mortar reaches the required value of the mortar content, the control unit controls the electromagnetic valve 18 at the bottom of the upper conical discharge pipe 5 to close, and at the same time, opens the electromagnetic valve 18 at the bottom of the quantitative barrel 15 to discharge the quantitative mortar into the container below;

[0028] 3. The three conical discharge pipes 5 and the electromagnetic valve 18 at the bottom of the quantitative barrel 15 can work independently, so multiple groups of quantitative mortar can be taken out at the same time without affecting each other, thereby improving construction efficiency;

[0029] 4. When there is no need to take out a certain amount of mortar, the driving motor 6 can be controlled to drive the active pulley 7 and the driven pulley 8 to rotate clockwise, so that the first spiral rotating rod 11 and the second spiral rotating rod 12 can drive the mortar in the mixing barrel 2 to turn from the bottom to the top, thereby ensuring that the mortar in the mixing barrel 2 flows at all times to avoid solidification.
