After the raw materials are added to the stirring device, they are easy to accumulate, the workability of the concrete is reduced, and the materials are easy to adhere to the inner wall of the mixing barrel, which is inconvenient to clean and causes waste. Since fiber concrete contains long fibers, the fibers are not easy to disperse in the mixing barrel. Secondly, for the currently commonly used vertically arranged mixing barrel, the concrete may be unevenly mixed due to the limitation of the rotation path of the stirrer, and the movement trajectory of the stirring blade is limited. The stirring speed and efficiency are usually lower than those of a horizontal mixer, which affects the stirring efficiency.

[0024] The support assembly 1 includes a bottom plate 101, the surface of the bottom plate 101 is connected to the support frame 4, universal wheels 102 are provided on both sides of the surface of the bottom plate 101 away from the support frame 4, the side wall of the bottom plate 101 is connected to an extension plate 103, and the surface of the extension plate 103 is threadedly connected with a positioning bolt 104, one end of the positioning bolt 104 is connected to a support foot 105, and the other end of the positioning bolt 104 is connected to a knob 106, such as Figure 7 As shown; the mixing barrel 2 and the support frame 4 are fixed by bolts.

[0028] Another technical solution adopted by the present invention is a fiber concrete mixing method, using a fiber concrete mixing device, and the specific operating steps are as follows: Step 1: Place cement and sand for preparing fiber concrete in the feed hopper 309, put fiber into the fiber feed barrel 308, turn on the drive motor 5, the feed motor 303 and the feed valve 3010, and mix the fiber, cement and sand in the mixing barrel 2 for no more than 0.5 min; Step 2, add the mixed liquid into the mixing barrel 2 through the water inlet pipe 13 and mix and stir for 2.4-2.6 minutes; Step 3: open the cap 8013, start the discharging motor 809, and collect the fiber concrete obtained after mixing.

[0029] The mixing and stirring rate in step 1 is 20-50 r / min, and the mixing and stirring rate in step 2 is 20-50 r / min. The mixed solution is a solution obtained by mixing water and an additive.

[0030] Among them, admixtures mainly include water reducers and air entraining agents. Preservatives, accelerators or retarders can be added according to actual needs to increase the performance of concrete.

[0031] The transmission shaft 302 is provided with a guide piece 307, which rotates under the action of the feed motor 303 to ensure that the raw materials put into the mixing barrel 2 can enter the mixing barrel 2 smoothly and not agglomerate in the fiber feed barrel 308; the first synchronous wheel 304 and the second synchronous wheel 306 rotate together and are connected to the synchronous belt 305, one end of one transmission shaft 302 is connected to the feed motor 303, but driven by the synchronous belt 305, the two transmission shafts 302 arranged parallel to each other will rotate synchronously; the raw materials can be weighed and put into the feed hopper 309, which is convenient for adding to the fiber feed barrel 308. The glass window 11 can observe the stirring situation in the mixing barrel 2 in real time. The discharge port 801 and the movable door 803 cooperate. When cleaning is needed, the movable door 803 is opened to clean the mixing barrel 2.

[0032] The first rotating gear 807 is meshed with the third rotating gear 8011, and the second rotating gear 808 is meshed with the fourth rotating gear 8012; the discharging motor 809 rotates to drive the third rotating gear 8011 and the fourth rotating gear 8012 to rotate, and the inner walls of the first discharging barrel 804 and the second discharging barrel 806 are both provided with stirring blades 8014. When the stirring blades 8014 are in fish scale shape and are respectively at 45°~60° to the inner walls of the first discharging barrel 804 and the second discharging barrel 806, the discharging effect is better. When discharging, the mixed fiber concrete can be stirred again, which has the effect of uniform discharging and preventing the fiber concrete from sticking to the inner wall of the discharging barrel; the gear intervals of the third rotating gear 8011 and the fourth rotating gear 8012 are different, so that the first discharging barrel 804 and the second discharging barrel 806 can rotate at different speeds.

[0033] The setting of the universal wheel 102 facilitates the movement of the stirring device; the rotation of the knob 106 adjusts the height of the extension plate 103 to adapt to the bottom plate 101 of different heights; the setting of the supporting foot 105 realizes the supporting effect on the bottom plate 101, ensuring the stability of the stirring device during the stirring process; there are two spiral blades 701, and the directions of rotation are opposite. This setting ensures that during the stirring process, the raw materials will gather in the middle of the stirring barrel 2. The spiral blade 701 is spiral and will rotate in the direction of the vortex during the rotation process; the rotation angle of the spiral blade 701 is 40°~50°, and the best rotation angle is 45°. The rotation directions of the two spiral blades 701 are relatively set, and the rotation diameter gradually decreases in the direction away from the inner wall of the mixing barrel 2, ensuring that the raw materials and fibers are concentrated in the middle of the mixing barrel 2 during the mixing process. The turning plate 704 and the wedge-shaped blade 706 play a stirring role, making the mixing more uniform; the scraper 703 scrapes the raw materials attached to the inner wall of the mixing barrel 2 and continues to stir. The setting of the turning plate 704 stirs the raw materials gathered in the middle to enhance the stirring effect; the setting of the wedge-shaped blade 706 stirs the raw materials scraped off by the scraper 703; the setting of the shaft seat 707 ensures the stability of the rotating shaft 6 during the rotation process.

[0034] There is a gap of 2 to 5 mm between the scraper 703 and the inner wall of the mixing barrel 2, which avoids direct contact between the scraper 703 and the inner wall of the mixing barrel 2 during the mixing process, and prevents the material from being stuck in the gap, ensuring easy cleaning. In step 1 of the fiber concrete mixing method, the mixing and stirring rate can be different. In the initial stage, the stirring speed is relatively low to ensure that the materials are mixed evenly; the speed is accelerated in the subsequent stage to make it mixed more thoroughly. There are many types of fibers added to fiber concrete, including glass fiber, polyvinyl alcohol fiber, polypropylene fiber, etc. The stirring speed can be adjusted according to the different requirements of the materials and the observation through the glass window 11, so that the fibers and aggregates are evenly distributed, avoiding stratification or fiber breakage caused by improper stirring speed. The second discharging barrel 806 and the first discharging barrel 804 are at an angle of 45° to 60° with the vertical direction of the mixing barrel 2. The discharging effect is best when the angle is 50°, which can ensure smooth discharging after the mixing is completed. There are no less than two support rods 3011, and the support rods 3011 are arranged relatively to each other, which can ensure that the force supporting the feed hopper 309 is uniform. The flange 3012 is used to connect to an external fiber pneumatic conveying device.
