[0037] At the upper part of the central position of the inner surface of the spraying machine housing 11, a turntable 21 is connected. In the middle of the bottom end of the turntable 21, a rotating rod 22 is connected. At the upper and lower parts of the outer surface of the rotating rod 22, support rods 24 are circumferentially and equally spaced. The scraping plate 25 is connected to the outside of the two support rods 24. The scraping plate 25 is attached to the inner surface of the spraying machine housing 11. On the outer surface of the rotating rod 22, mixing rods 23 are circumferentially and equally spaced;

[0038] The concrete material and water body can be uniformly poured into the interior of the spraying machine housing 11, and the scraping plate 25 is attached to the inner wall of the spraying machine housing 11. By rotating, the scraping plate 25 is used to scrape the concrete attached to the inner wall of the spraying machine housing 11.

[0039] It further includes a fixing component, the fixing component includes an inner groove 31, a limiting semi-ring 32, an inserting rod 33, a fixing ring 34, and a support block 35;

[0040] In the middle of one side of the outer surface of the support rod 24, an inner groove 31 is opened. At the upper and lower parts of one side of the outer surface of the scraping plate 25, support blocks 35 are connected. On the outside of the support blocks 35, inserting rods 33 are connected. The inserting rods 33 are connected to the inside of the inner groove 31 by insertion. On the outer surface of the inserting rods 33, fixing rings 34 are connected;

[0041] After long-term use, the fixing ring 34 is removed, and then the scraping plate 25 is pulled outwards, so that the inserting rods 33 and the support blocks 35 are separated from the inner groove 31, and the scraping plate 25 can be separately removed.

[0042] At both ends of the outer surface of the support rod 24, limiting semi-rings 32 are connected, and the limiting semi-rings 32 are attached to one side of the outer surface of the inserting rods 33;

[0043] After the insertion rod 33 is inserted into the inner groove 31, the insertion rod 33 will be attached to the inner wall of the limit semi-ring 32, and the limit semi-ring 32 is used to play a limiting role.

[0044] The body component further includes a spray head 12, a support base 13, moving wheels 14 and a push handle 15;

[0045] One end of the top of the support base 13 is connected to a spraying machine housing 11, the other side of the outer surface of the support base 13 is connected to a push handle 15, and a group of moving wheels 14 are symmetrically connected to the bottom of the support base 13;

[0046] The staff holds the push handle 15 and uses the moving wheels 14 at the bottom to move the spraying machine housing 11 to the position where it is needed.

[0047] The working principle is as follows. First, the insertion rod 33 and the support block 35 are inserted into the inner groove 31, and the fixing ring 34 will be fixed on the outer surface of the insertion rod 33 to fix the inserted insertion rod 33. In this way, the scraper 25 will be installed on the outside of the support rod 24;

[0048] The concrete mixing material and water are uniformly poured into the spraying machine housing 11. Through the operation of the motor, the rotating rod 22 rotates 360 degrees. The mixing rod 23 on the outer surface of the rotating rod 22 is used to mix the concrete mixing material and water. The scraper 25 scrapes the concrete mixing material and water attached to the inner wall of the spraying machine housing 11, so that the concrete mixing material and water can be better mixed together, increasing the strength of the mixed concrete, greatly improving the construction efficiency, reducing the labor intensity, and improving the project quality.

[0049] Please refer to Figure 1 、 Figure 2 、 Figure 4 As shown in

The damping ring 42 is connected to the lower part of the outer surface of the damping rod 44. A limit block 45 is fixedly connected to the top of the damping rod 44;

[0051] By moving the damping ring 42 outside the damping rod 44, the scraper 25 can be pulled out or pushed into the spraying machine housing 11.

[0052] The inside of the limit block 45 is evenly provided with a slot 46, and the top of the damping ring 42 is evenly connected with an insertion ring 43. The insertion ring 43 is connected to the inside of the slot 46 by insertion.

[0053] When the damping ring 42 is lifted upward, the insertion ring 43 will be inserted into the inside of the slot 46 to fix the lifted damping ring 42.

[0054] Working principle: First, the damping ring 42 can move up and down outside the damping rod 44. After long-term use, the damping ring 42 is lifted upward, so that the insertion ring 43 is inserted into the inside of the slot 46 to fix the lifted damping ring 42, making the internal scraper 25 exposed, which is convenient for the staff to detach the scraper 25 separately for maintenance.

[0055] Finally, the damping ring 42 is moved downward, so that the scraper 25 is moved into the inside of the spraying machine housing 11 for subsequent scraping work.
