[0002] Concrete glue reducer refers to a chemical admixture that can effectively reduce the amount of gel material while keeping the water-cement ratio basically unchanged and the slump and 28d compressive strength of concrete unchanged. It is a new type of concrete additive different from concrete water reducer. It can destroy small-volume aggregates, allowing cement particles to fully participate in the hydration reaction and reduce the amount of cementitious material cement.

[0003] When discharging the gel reducer, a discharging device can be used to better quantitatively discharge the gel reducer, ensure its discharging rate, and further improve the production efficiency of concrete. However, in the prior art, since the concrete gel reducer has a certain viscosity, when discharging the concrete gel reducer, the concrete gel reducer will adhere to the side wall of the quantitative box, resulting in inaccurate discharging.

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-6 As shown, a quantitative discharging device for concrete glue reducing agent comprises a motor 1 and a collecting barrel 2, the motor 1 is assembled and connected to the upper side of the collecting barrel 2, the output shaft of the motor 1 is drivingly connected to a rotating shaft 11, a screw 12 is fixedly connected to the lower part of the rotating shaft 11, the screw 12 is threadedly connected to a threaded sleeve 13, a tapered sleeve 14 is fixedly connected to the lower end of the threaded sleeve 13, a first baffle plate 15 is fixedly connected to the upper part of the tapered sleeve 14, the first baffle plate 15 is slidably connected to the side wall of the collecting barrel 2, a second baffle plate 16 rotatably connected to the threaded sleeve 13 is arranged above the first baffle plate 15, a plurality of evenly arranged discharging holes 17 are arranged at the same position of the first baffle plate 15 and the second baffle plate 16, a rotating mechanism 3 is arranged on the upper side of the second baffle plate 16, the threaded sleeve 13 is provided with a positioning ring 18 on the upper side of the second baffle plate 16, a conical barrel 21 is arranged at the lower end of the collecting barrel 2, the internal cavity of the conical barrel 21 is consistent with the shape of the conical sleeve 14, and a discharging portion 22 is arranged at the lower end of the conical barrel 21;

[0029] The collecting barrel 2 is provided with a transparent window 24 , and a scale 241 is provided on the surface of the transparent window 24 .

[0030] The technical solution of this embodiment is adopted, the rubber reducing agent is installed in the collecting barrel 2, the rotating shaft 11 is located in the middle of the collecting barrel 2, the motor 2 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the screw 12 to rotate. The screw 12 is threadedly connected with the threaded sleeve 13 and the tapered sleeve 14, and the first baffle plate 15 is slidably connected with the collecting barrel 2. The first baffle plate 15 and the collecting barrel 2 cannot rotate relative to each other, so the threaded sleeve 13 will not rotate. When the screw 12 rotates, the threaded sleeve 13 moves up and down relative to the screw 12. The positioning ring 18 is used to fix the upper and lower directions of the second baffle plate 16 and the first baffle plate 15, so that the second baffle plate 16 moves up and down with the first baffle plate 15, and the second baffle plate 16 is rotatably connected with the threaded sleeve 13, so the rotating mechanism 3 is used to drive the second baffle plate 16 to rotate, so that the discharge holes 17 of the first baffle plate 15 and the second baffle plate 16 are staggered. In the initial state, the first baffle plate 15 and the second baffle plate 16 are arranged so that the discharge holes 17 of the first baffle plate 15 and the second baffle plate 16 are staggered. The discharge holes 17 of the second baffle plates 16 are staggered, so that the glue reducing agent is located above the second baffle plate 16 of the collecting barrel 2. By rotating the rotating mechanism 3, the first baffle plate 15 is aligned with the second baffle plate 16, and the glue reducing agent falls from the discharge hole 17 to the bottom of the collecting barrel 2. When it is necessary to discharge, the first baffle plate 15 is aligned with the second baffle plate 16 to let the glue reducing agent fall below the collecting barrel 2. The scale of the glue reducing agent is observed through the transparent window 24, and the glue reducing agent reaches the indicated level. After setting the scale, the second baffle plate 16 is rotated by the rotating mechanism 3 so that the second baffle plate 16 blocks the discharge hole 17 and opens the discharge part 22. Then, the threaded sleeve 13 is moved downward along the screw 12 by controlling the motor 1, and the second baffle plate 16, the first baffle plate 15 and the tapered sleeve 14 are moved downward to scrape off the rubber reducing agent adhering to the side wall of the collecting barrel 2. Finally, the tapered sleeve 14 reaches the cavity of the conical barrel 21 to discharge all the rubber reducing agent at the bottom of the collecting barrel 2.

[0031] Reference Figure 1 : A feeding port 23 is provided on the upper side of the collecting barrel 2.

[0032] In this embodiment, the rubber reducing agent enters into the collecting barrel 2 from the feed inlet 23 .

[0033] Reference Figure 1-4 The rotating mechanism 3 includes a retractable rotating rod 31, an arc groove 32 is opened on the upper part of the collecting barrel 2, the center of the arc groove 32 and the center of the first baffle plate 15 are located on the same axis, the rotating rod 31 is slidably connected to the arc groove 32, the rotating rod 31 is fixedly connected to the arc baffle 33 on the lower side of the collecting barrel 2, and a positioning mechanism 34 is provided at the upper end of the rotating rod 31.

[0034] In this embodiment, the arc baffle 33 is used to cover the arc groove 32. The arc baffle 33 is larger than the arc groove 32. When the rotating rod 31 is located at both ends of the arc groove 32, the arc baffle 33 can cover the arc groove 32. The positioning mechanism 34 is used to fix the position of the rotating rod 31.

[0035] Reference Figure 5 The rotating rod 31 includes a sliding rod 311 and a sliding rod sleeve 312. The lower end of the sliding rod sleeve 312 is fixedly connected to the second baffle plate 16. The sliding rod 311 is fixedly connected to the upper side of the collecting barrel 2 with a positioning sleeve 313 which is slidably connected to the upper side of the collecting barrel 2.

[0036] In this embodiment, the slide bar 311 slides in the slide bar sleeve 312. When the second material baffle plate 16 moves downward, the slide bar sleeve 312 moves downward along with the second material baffle plate 16. The positioning sleeve 1313 is used to prevent the slide bar 311 from moving downward.

[0037] Reference Figure 4 The positioning mechanism 34 includes a straight slot plate 341, one end of the straight slot plate 341 is fixedly connected to the upper end of the rotating rod 31, and the other end is slidably connected to a positioning rod 342. The lower end of the positioning rod 342 is provided with an arc plate 343 fixedly connected to the upper side of the collecting barrel 2, and both ends of the arc plate 343 are provided with positioning holes with the same diameter as the lower end of the positioning rod 342.

[0038] In this embodiment, the positioning holes at both ends of the arc plate 343 are used to position the positioning rod 342. When the positioning rod 342 is in one positioning hole, the discharge holes 17 of the first baffle plate 15 and the second baffle plate 16 are in the same position. When the positioning rod 342 is in the other positioning hole, the second baffle plate 16 blocks the discharge hole 17 of the first baffle plate 15. When moving the position of the positioning rod 342, first move the positioning rod 342 upward so that the lower end of the positioning rod 342 falls off the positioning hole, then move the positioning rod 342 in the direction of the other positioning hole, and then lower the positioning rod 342. The positioning rod 342 falls into the positioning hole under the action of gravity.

[0039] Reference Figure 1 The discharge portion 22 includes a discharge valve 221 and a discharge pipe 222, and the discharge valve 221 is assembled and connected with the discharge pipe 222.

[0040] In this embodiment, the discharge valve 221 is used to control the discharge of material from the discharge pipe 222 .

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
