[0033] Reference Figure 1-5 as well as Fig. 9 A slurry collecting seat 5 matching with the discharge port of the mixing drum 3 is fixedly installed on the body 2, a slurry lowering pipe 6 is fixedly connected to the slurry collecting seat 5, a dispersion seat 9 is installed on the body 2 through a fixed component, and a dispersion structure is installed on the dispersion seat 9;

[0034] The following points are worth noting:

[0035] 1. A retaining frame 17 that matches the upper end of the mixing drum 3 is fixedly mounted on the slurry collecting seat 5.

[0036] 2. The specific shape of the retaining frame 17 is Figure 1 as well as Figure 2 It can be directly seen in the figure that the shape allows the concrete slurry to slide down along the inner wall of the retaining frame 17 to the slurry collecting seat 5 better after it contacts the inner wall of the retaining frame 17 .

[0037] 3. A groove is provided on the slurry collecting seat 5. Figure 1 It can be seen that the configuration is wide at the top and narrow at the bottom, so that the slurry entering the slurry collecting seat 5 can be better passed through the lower slurry pipe 6 and enter the dispersion seat 9.

[0038] 4. The fixing assembly consists of a plurality of fixing rods 7 and a plurality of fixing rods 8. Four fixing rods 7 are fixedly installed on the outer wall of the vehicle body 2 away from the front end 1, and the length of the two upper fixing rods 7 is less than the length of the two lower fixing rods 7. A fixing rod 2 8 fixedly connected to the dispersion seat 9 is fixedly installed on the side surface of the four fixing rods 7 close to the dispersion seat 9.

[0039] 5. The dispersion structure consists of a connecting blind hole 10, a lower pulp chamber 11, a connecting chamber 12, a pulp outlet groove 13, a servo motor 14, a rotating shaft 15 and an adjusting rod 16. The dispersion seat 9 is provided with a connecting blind hole 10, a lower pulp chamber 11, a connecting chamber 12 and a pulp outlet groove 13, and the lower pulp chamber 11 is connected to the connecting blind hole 10 and the connecting chamber 12, and the connecting chamber 12 is connected to the pulp outlet groove 13.

The end of the rotating shaft 15 away from the servo motor 14 is rotatably installed on the inner wall of the connecting chamber 12, and an adjusting rod 16 is fixedly installed on the rotating shaft 15.

[0040] 6. The arrangement of the dispersion structure can play a certain role in limiting and guiding the flow direction of the slurry when it flows out of the dispersion seat 9, so that the slurry can fall more dispersedly on the road surface where it is needed.

[0041] 7. A layer of elastic pad 18 is fixedly installed on both sides of the adjustment rod 16.

[0042] Reference Figure 1 , Figure 3 , Figure 6 as well as Figure 7 The dispersion seat 9 is fixedly mounted with a mounting plate 20 through two fixing frames 19, and a scraping seat 1 23 is mounted on the mounting plate 20 through a height adjustment structure, and both ends of the scraping seat 1 23 are mounted with a scraping seat 2 26 through a disassembly structure;

[0043] The following points are worth noting:

[0044] 1. The height adjustment structure consists of a servo motor 21, a screw, a ball nut and a mounting groove 22. The servo motor 21 is fixedly mounted on the upper surface of the mounting plate 20, and the driving end of the servo motor 21 is fixedly mounted with a screw. A mounting groove 22 is opened on the scraping seat 23, and a ball nut matching the screw is installed in the mounting groove 22.

[0045] 2. The purpose of the height adjustment structure is to adjust the height of the lower end of the scraping seat 23 as needed, so as to facilitate better use.

[0046] 3. The upper end of the scraping seat 23 is arranged in an arc shape, so that the slurry is not easy to adhere to its outer wall.

[0047] 4. The disassembly and assembly structure consists of a slot 24 and a block 25. A slot 24 is provided at both ends of the scraping seat 23. A block 25 matched with the slot 24 is fixedly installed at one end of each of the two scraping seats 26.

[0048] 5. The setting of the second scraping seat 26 is convenient for use according to the width of the road. Specifically, the scraping seats 26 of different lengths can be set for use; or multiple scraping seats 26 can be set for use. At this time, a clamping groove 24 is also set on the side of the scraping seat 26 away from the clamping block 25, so that multiple scraping seats 26 can be clamped together for use.

[0049] Reference Figure 3 as well as Figure 8 A mounting frame 29 is installed on each of the first and second scraping seats 23 and 26 through a disassembly assembly component, a sliding plate 31 is installed on each mounting frame 29 through a lifting assembly, and a plurality of combing rods 32 are fixedly installed on each sliding plate 31 at equal intervals;

[0050] The following points are worth noting:

[0051] 1. The disassembly and assembly components are composed of a second card slot 27 and a second card block 28. The outer walls of the first scraping seat 23 and the second scraping seat 26 are each provided with a second card slot 27. The outer wall of each mounting frame 29 is fixedly provided with a second card block 28 that matches the second card slot 27.

[0052] 2. The disassembly and assembly components are arranged so that when multiple scraping seats 26 are installed, multiple sliding plates 31 can be arranged for use (used in conjunction with the above-mentioned arrangement of multiple scraping seats 26).

[0053] 3. The lifting component is an electric push rod 30 , which is fixedly mounted on the mounting frame 29 , and the lower end of the electric push rod 30 passes through the upper end of the mounting frame 29 and is fixedly connected to the upper surface of the sliding plate 31 .

[0054] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0055] In the present invention, when it is used, an appropriate scraping seat 26 is selected according to the width of the highway, and the height of the scraping seat 23 is adjusted according to the required laying height of the concrete slurry. The servo motor 21 is turned on, and the servo motor 21 works to adjust the height of the scraping seat 23 through the cooperation of the screw rod and the ball nut.

[0056] The matching mounting frame 29 is installed on the scraping seat 1 23 and the corresponding scraping seat 2 26, and then the electric push rod 30 is turned on as needed, and the height of the lower end of the combing rod 32 is adjusted by the operation of the electric push rod 30, so as to facilitate the screening of large particles in the slurry as needed.

[0057] After the mixing drum 3 has worked for a period of time, the mixed concrete can be transported to the slurry collecting seat 5, and the concrete slurry then enters the dispersion seat 9 through the lower slurry pipe 6. At this time, the servo motor 14 is turned on, and the servo motor 14 drives the adjusting rod 16 to rotate through the rotating shaft 15. The rotation of the adjusting rod 16 allows the slurry to slide out better along the surface of the adjusting rod 16 (which has an inclination after rotation), thereby achieving the effect of dispersing the concrete slurry, so that the concrete slurry can slide out from the dispersion seat 9 at different angles, thereby greatly reducing the occurrence of a large amount of concrete slurry gathering.

[0058] At the same time, as the vehicle body moves, the comb rod 32 and the first and second scraping seats 23 and 26 are driven to move together, so as to screen out large particles of the scattered concrete slurry and further scrape and disperse it.
