[0034] In use, a certain amount of concrete raw materials is put into the mixing barrel 1, and then the concrete quick-setting agent powder is put into the top surface of the ingredient column 2 through the material conveying pipe 25, and the concrete quick-setting agent powder enters the quantitative hole 21, and the U-shaped plate 24 arranged at the quantitative hole 21 can prevent the concrete quick-setting agent powder above the quantitative hole 21 from separating from the top surface of the ingredient column 2; during the process of putting the concrete quick-setting agent powder into the quantitative hole 21 through the material conveying pipe 25, the rotating disc 22 is driven to rotate by the first stepper motor arranged below, and the scraper 23 is driven to reciprocate at a certain angle on the top surface of the ingredient column 2, and when the scraper 23 rotates, the concrete quick-setting agent powder above the quantitative hole 21 is pushed in the U-shaped plate 24, so that the concrete quick-setting agent powder above the quantitative hole 21 is close to the inner wall of the U-shaped plate 24, and when the quantitative hole 21 is filled with the concrete quick-setting agent powder, the quantitative hole 21 is scraped flat by the scraper 23, and then the feeding of the quantitative hole 21 is stopped; then the second stepper motor is started, and the annular baffle 31 is driven to rotate, the leakage hole on the annular baffle 31 is vertically coincided with the lower hole of the quantitative hole 21, and the concrete quick-setting agent powder filled in the quantitative hole 21 falls into the lower mixing barrel 1, and the mixing assembly in the mixing barrel 1 mixes the concrete quick-setting agent powder with the concrete raw materials; the content of the quantitative hole 21 is a specified value, and the worker only needs to fill the quantitative hole 21 and then put it into the mixing barrel 1, so as to complete the quantitative batching and mixing of the concrete raw materials and the concrete quick-setting agent powder, and the concrete quick-setting agent does not need to be weighed and transported separately, which is simple and convenient for the production of a large amount of quick-setting concrete.

[0035] As Figure 5As shown, the annular peripheral surface of the ingredient column 2 is provided with a plurality of vibrators 3; when the feed pipe 25 feeds the concrete accelerator powder into the quantitative hole 21, the vibrator 3 is started, and the vibrator 3 is vibrated to drive the ingredient column 2 to vibrate synchronously; when the concrete accelerator powder enters the quantitative hole 21, the quantitative hole 21 vibrates synchronously, and the internal concrete accelerator powder is close to each other by the vibration force, preventing the hollow inside the quantitative hole 21 after filling the concrete accelerator powder, and affecting the accuracy of the quantitative hole 21.

[0036] A pair of pushing plates 4 is attached to the surface of the U-shaped plate 24 facing the quantitative hole 21, and a pair of first telescopic rods 41 is attached to the surface of the U-shaped plate 24. The output end of the first telescopic rod 41 penetrates the U-shaped plate 24 and is connected with the vertical surface of the pushing plate 4; when the concrete accelerator powder is repeatedly fed into the quantitative hole 21, the first telescopic rod 41 is started, and the first telescopic rod 41 drives the pushing plate 4 to move back and forth, which is synchronized with the direction of the scraper 23, so that the pushing plate 4 is not blocked by the scraper 23 when moving, and the pushing plate 4 pushes the concrete accelerator powder near the U-shaped plate 24 at the hole of the quantitative hole 21 into the inside of the quantitative hole 21 when moving, realizing the full use of the concrete accelerator powder that has not entered the quantitative hole 21, and avoiding the accumulation of concrete accelerator powder on the top surface of the ingredient column 2.

[0038] Example two

[0039] As shown in Figure 5As shown, the comparative example one, wherein another embodiment of the present application is: the inside of the quantitative hole 21 is inserted with a plurality of filling barrels 6, the inner diameter of the plurality of filling barrels 6 decreases in turn; in the production of quick-setting concrete, it is necessary to first prepare the concrete quick-setting agent, and when the inventory of the concrete quick-setting agent is insufficient, the concrete raw materials can be directly mixed with the concrete quick-setting agent processing raw materials, which can optimize the production process. Specifically, the various processing raw materials of the concrete quick-setting agent are put into different quantitative holes 21, and at the same time, the filling barrels 6 are inserted into different quantitative holes 21 according to the need for each time, so that the capacity of the quantitative hole 21 changes each time, and the number of the dosing column 2 in different quantitative holes 21 can also be replaced as needed. The concrete quick-setting agent processing raw materials are directly mixed with the concrete raw materials, which optimizes the batching process.

[0040] As shown in Figures 1 to 3 The support 12 includes a support rod 121, a drive motor 122 and a friction wheel 123. The bottom end of the support rod 121 is vertically installed on the top surface of the receiving member 11. The drive motor 122 is located between the support rod 121 and the friction wheel 123. The output end of the drive motor 122 is installed at the center of the bottom surface of the friction wheel 123. The annular surface of the dosing column 2 is provided with an annular groove 29. The friction wheel 123 is embedded in the annular groove 29 and can drive the annular groove 29 to rotate when rotating. During the batching process, the drive motor 122 is started, the drive motor 122 drives the friction wheel 123 to rotate, the friction wheel 123 drives the annular groove 29 to rotate through friction, and then the dosing column 2 is rotated. When the orifice below the quantitative hole 21 on the dosing column 2 drops the concrete quick-setting agent processing raw materials, different concrete quick-setting agent processing raw materials are stacked in the mixing barrel 1, which is beneficial to the rapid mixing of the concrete quick-setting agent processing raw materials and the concrete raw materials in the mixing barrel 1 by the stirring assembly in the mixing barrel 1.

[0041] As shown in Figure 5 The folding plate 28 is rotatably connected between the scraper 23 and the U-shaped plate 24. The folding plate 28 is connected by two rotatably connected plate members. The connection between the U-shaped plate 24 and the folding plate 28 is located at the end of the U-shaped plate 24. When the scraper 23 reciprocates, the concrete quick-setting agent processing raw materials put in different quantitative holes 21 are different. The folding plate 28 between the scraper 23 and the U-shaped plate 24 limits the concrete quick-setting agent processing raw materials from separating from the surrounding area of the U-shaped plate 24 and the folding plate 28, effectively reducing the probability of independent mixing of different concrete quick-setting agent processing raw materials on the top surface of the dosing column 2.

[0042] As shown in Figure 6As shown, the bottom surface of the annular baffle 31 is provided with a plurality of vertical baffles 7, after the annular baffle 31 is rotated to open the lower aperture of the quantitative hole 21, the raw material powder falling off from the lower aperture of the quantitative hole 21 is thrown out by centrifugal force when the dosing column 2 rotates, and the raw material powder after being thrown out can be blocked by the vertical baffles 7; the concrete accelerator processing raw material falling off from the lower aperture of the quantitative hole 21 is thrown out under the action of centrifugal force when the quantitative hole 21 rotates, and then is blocked by the vertical baffles 7, and finally falls into the mixing bucket 1, avoiding the situation that a large amount of concrete accelerator processing raw material is thrown out and falls off from the mixing bucket 1, and ensuring the dosing effect.

[0043] As shown, Figure 4 As shown, the annular surface of the dosing column 2 is fixedly connected with a plurality of fixed parts 81, the end of the fixed part 81 away from the dosing column 2 is fixedly connected with the second telescopic rod 8, the top end of the output end of the second telescopic rod 8 is fixedly connected with the connecting frame 82, the bottom end of the connecting frame 82 is fixedly connected with the scraping plate 83, and the size diameter of the scraping plate 83 is the same as the inner diameter of the innermost filling cylinder 6 in the quantitative hole 21; when the second telescopic rod 8 drives the scraping plate 83 to move downward through the connecting frame 82, the scraping plate 83 can completely enter the quantitative hole 21; the material conveying pipe 25 includes a first pipe 251 and a second pipe 252, the second pipe 252 is inserted into the first pipe 251, and a third telescopic rod 27 is arranged between the first connecting part 26 and the second pipe 252; when the concrete accelerator processing raw material falls off in the quantitative hole 21, the second telescopic rod 8 is controlled, the second telescopic rod 8 drives the scraping plate 83 to move downward through the connecting frame 82, and then extends into the quantitative hole 21 to remove the concrete accelerator processing raw material remaining on the inner wall of the quantitative hole 21, so as to ensure that the quantitative hole 21 completely falls; in addition, when the filling cylinder 6 is inserted into the quantitative hole 21, the size of the scraping plate 83 is adjusted so that the diameter of the scraping plate 83 is matched with the inner diameter of the filling cylinder 6, and the concrete accelerator processing raw material remaining on the inner wall of the filling cylinder 6 can also be removed; it should be noted that when the scraping plate 83 moves downward, the second pipe 252 needs to be driven to move away from the moving path of the scraping plate 83 through the third telescopic rod 27, so as to avoid that the second pipe 252 blocks the movement of the scraping plate 83, and the position of the first pipe 251 will not block the movement of the scraping plate 83; at the same time, when the scraping plate 83 moves downward, the scraping plate 23 needs to be driven to move away from the aperture position of the quantitative hole 21 through the rotating disc 22 and the first stepping motor, so as to also avoid that the scraping plate 23 blocks the movement of the scraping plate 83.

[0044] The connecting position of the fixed part 81 on the annular surface of the dosing column 2 is higher than the height of the friction wheel 123, and the fixed part 81 and the connected second telescopic rod 8 are not blocked by the friction wheel 123 when the dosing column 2 rotates; the fixed part 81 and the second telescopic rod 8 are prevented from being blocked by the friction wheel 123 when the dosing column 2 rotates synchronously, so as to ensure the implementability of the device.

[0045] When working, a certain amount of concrete raw materials is put into the mixing barrel 1, and then the concrete accelerator powder is put into the top surface of the batching column 2 through the feeding pipe 25. The concrete accelerator powder enters the quantitative hole 21, and the U-shaped plate 24 arranged at the hole of the quantitative hole 21 can prevent the concrete accelerator powder above the quantitative hole 21 from separating from the top surface of the batching column 2. During the process of putting the concrete accelerator powder into the quantitative hole 21 through the feeding pipe 25, the rotating disc 22 is driven to rotate by the first stepping motor arranged below, and the rotating disc 22 drives the scraper 23 to reciprocate at a certain angle on the top surface of the batching column 2. When the scraper 23 rotates, the concrete accelerator powder above the hole of the quantitative hole 21 is pushed in the U-shaped plate 24, so that the concrete accelerator powder above the hole of the quantitative hole 21 is close to the inner wall of the U-shaped plate 24. After the quantitative hole 21 is filled with the concrete accelerator powder by the feeding pipe 25, the hole of the quantitative hole 21 is scraped flat by the scraper 23, and at this time, the feeding of the quantitative hole 21 is stopped. Then, the second stepping motor is started, and the annular baffle 31 is driven to rotate. The leakage hole on the annular baffle 31 coincides with the hole below the quantitative hole 21 in the vertical direction, and the concrete accelerator powder filled in the quantitative hole 21 falls into the mixing barrel 1 below. The mixing assembly in the mixing barrel 1 mixes the concrete accelerator powder with the concrete raw materials. The content of the quantitative hole 21 is a specified value, and the worker only needs to fill the quantitative hole 21 and then put it into the mixing barrel 1, so as to complete the quantitative batching and mixing of the concrete raw materials and the concrete accelerator powder. It is not necessary to weigh the concrete accelerator separately and then transport and mix. The operation is simple and beneficial to the production of a large amount of rapid-hardening concrete. When the concrete accelerator powder is put into the quantitative hole 21 by the feeding pipe 25, the vibrator 3 is started, and the vibrator 3 drives the batching column 2 to vibrate synchronously. When the concrete accelerator powder enters the quantitative hole 21, the quantitative hole 21 vibrates synchronously, and the concrete accelerator powder inside moves close to each other by the vibration force, so as to prevent the hollow inside the quantitative hole 21 after filling the concrete accelerator powder.

[0046] Wherein in the process of repeatedly putting the concrete accelerator powder into the quantitative hole 21, the first telescopic rod 41 is started to drive the pushing plate 4 to move back and forth, and the moving direction is synchronous with the direction of the scraper 23, so as to avoid the pushing plate 4 being blocked by the scraper 23 when moving, and the concrete accelerator powder near the U-shaped plate 24 at the hole of the quantitative hole 21 is pushed into the inside of the quantitative hole 21 when the pushing plate 4 moves; wherein in the process of putting the concrete accelerator powder filled in the quantitative hole 21 into the mixing barrel 1 below, when there is a large air flow outside, a guide pipe 5 is arranged at the bottom surface of the annular baffle 31, the guide pipe 5 is communicated with the material leakage hole, the bottom end of the guide pipe 5 extends into the inside of the mixing barrel 1, and when the material leaks from the quantitative hole 21, the concrete accelerator powder enters into the inside of the mixing barrel 1 through the guide pipe 5, so as to reduce the influence of the outside air flow on the concrete accelerator powder feeding; wherein in the production of the quick-setting concrete, the concrete accelerator ingredients need to be prepared in advance, when the inventory of the concrete accelerator is insufficient, the concrete raw materials can be directly matched with the concrete accelerator processing raw materials, so as to optimize the production process, and specifically, the concrete accelerator processing raw materials are put into the quantitative hole 21, at the same time, the filling cylinder 6 is inserted into different quantitative holes 21 according to the need of each time, so that the capacity of each time of the quantitative hole 21 is changed, and the number of the ingredient columns 2 of different quantitative holes 21 can also be replaced according to the need;

[0047] Wherein in the process of preparing the ingredients, the driving motor 122 is started to drive the friction wheel 123 to rotate, the friction wheel 123 drives the annular groove 29 to rotate through friction, and then the ingredient column 2 is rotated, when the hole below the quantitative hole 21 on the ingredient column 2 falls the concrete accelerator processing raw materials, different concrete accelerator processing raw materials are superimposed in the mixing barrel 1, which is beneficial to the mixing assembly in the mixing barrel 1 to quickly mix the concrete accelerator processing raw materials in the barrel with the concrete raw materials; wherein the concrete accelerator processing raw materials put on different quantitative holes 21 are different when the scraper 23 moves back and forth, the folding plate 28 arranged between the scraper 23 and the U-shaped plate 24 limits the concrete accelerator processing raw materials from separating from the surrounding area of the U-shaped plate 24 and the folding plate 28; wherein the concrete accelerator processing raw materials are thrown out under the action of the centrifugal force when the quantitative hole 21 falls the concrete accelerator processing raw materials from the hole below, and then are blocked by the vertical baffle 7, and finally fall into the mixing barrel 1; wherein when the concrete accelerator processing raw materials fall in the quantitative hole 21, the second telescopic rod 8 is controlled, the second telescopic rod 8 drives the scraper 83 to move downward through the connecting frame 82, and then extends into the quantitative hole 21 to remove the residual concrete accelerator processing raw materials on the inner wall of the quantitative hole 21, so as to ensure that the quantitative hole 21 falls completely; wherein the prevention fixing part 81 is prevented from being blocked by the friction wheel 123 when the ingredient column 2 rotates synchronously with the second telescopic rod 8, so as to ensure the implementability of the device.
