When the magnet bar 7 is inserted into the scraping through hole 811, the scraping bar 835 is vertically arranged and abuts against the peripheral wall of the magnet bar 7.
As the wiper 835 wipes off the concrete slurry adhering to the peripheral wall of the magnet bar 7, a portion of the concrete slurry slides down the peripheral wall of the wiper 832, which will affect the rotation of the wiper 832 once the concrete slurry slides into the slot of the wiper groove 812. Therefore, in order to prevent the concrete slurry from sliding to the junction of the lower end surfaces of the slurry scraping ring groove 812 and the slurry scraping plate 81, and simultaneously guide the concrete slurry sliding on the slurry scraping ring groove 832 to drop, referring to fig. 4 and 5, the section of the slurry guiding plate 833 along the axis direction of the hinge rotating rod 831 is triangular, and one side of the slurry guiding plate 833 facing away from the slurry scraping ring groove 832 is pointed, so that one inclined edge of the slurry guiding plate 833 is connected with the slurry scraping ring groove 832, when the concrete slurry flows to the tip of the slurry guiding plate 833, the concrete slurry is prevented from sliding into the slurry scraping ring groove 812 due to the shape of the slurry guiding plate 833, and the rotating space of the slurry scraping ring groove 832 is protected. Meanwhile, one end of the slurry guiding plate 833 corresponding to the slurry scraping through hole 811 is a slurry guiding convex surface 836, so that the sliding track of the concrete slurry on the slurry guiding plate 833 is shortened, and the concrete slurry is guided to drop quickly.
In order to avoid the concrete paste adhering to the scraping teeth 832 and the paste guiding plate 833, the paste guiding plate 833 and the scraping teeth 832 are coated with a nano coating with hydrophobic property. The nano-coating causes the concrete slurry to roll down in a drop-like fashion, reducing the amount of adhesion of the concrete slurry to the surfaces of the scraping teeth 832 and the slurry guiding plate 833. On the one hand, the rotation of the follow-up scraping teeth 832 is facilitated, and on the other hand, the waste amount of concrete slurry is further reduced.
The implementation principle of the embodiment of the application for the ultra-high performance concrete fiber orientation device is as follows: when magnet strip 7 rises from mould 9, lifting unit 3 drives backup pad 2 and rises, the pole section that connecting rod 821 is located the regulation pole 822 reduces, magnet strip 7 rises and magnet strip 7's week wall and scrape tooth 832 slip and support tightly, thereby scrape the concrete thick liquid of adhesion on the magnet strip 7 through scraping thick liquid strip 835 and scrape away magnet strip 7, the concrete thick liquid of scraping partly drip in mould 9, can avoid concrete thick liquid to splash to the outside of mould 9 through scraping thick liquid board 81, another part then flows down along the perisporium of scraping tooth 832, can block concrete thick liquid flow to scraping thick liquid annular 812 and scraping thick liquid board 81 lower terminal surface junction through guiding thick liquid convex surface 836 and can guide concrete thick liquid drip in mould 9 through guiding thick liquid convex surface 836, can avoid concrete thick liquid adhesion on scraping thick liquid subassembly 8 through the nano-coating, thereby reduce the quantity of concrete adhesion on the magnet on the whole, reduce the waste cost of concrete.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
