DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When mixing concrete, a mixing device is needed. The mixing device provided by the utility model can achieve that after mixing the concrete, the force-bearing plate 13 and the mixing blade 503 are overlapped by squeezing the annular frame 10, and the inner wall of the mixing box 3 is scraped by driving the L-shaped scraper 14 to rotate, so as to avoid the inner wall being adsorbed and then directly cleaned, resulting in material waste.

[0026] like Figure 1 - Figure 5As shown, the utility model provides a technical solution: a concrete mixing device, comprising a bottom plate 1 and an annular frame 10, a U-shaped frame 2 is fixedly connected to the upper side of the bottom plate 1, a mixing box 3 is rotatably matched on the inner wall of the U-shaped frame 2, a sealing cover 4 is arranged on the upper side of the mixing box 3, a stirring mechanism 5 is arranged on the sealing cover 4, a feeding pipe 6 is arranged on the upper side of the sealing cover 4, a discharge valve 7 is arranged on one side of the mixing box 3, an annular groove 8 is provided on one side of the inner wall of the mixing box 3, a rotating block 9 is slidably matched on the inner wall of the annular groove 8, a lifting groove 11 is provided on one side of the annular frame 10, a limiting rod 12 matched with the rotating block 9 is fixedly connected to the inner wall of the lifting groove 11, a spring 22 is arranged between the lifting groove 11 and the rotating block 9, a force plate 13 is fixedly connected to one side of the inner wall of the annular frame 10, an L-shaped scraper 14 in contact with the mixing box 3 is fixedly connected to the lower side of the annular frame 10, a turning mechanism 15 is arranged between the bottom plate 1 and the mixing box 3, and a linkage mechanism 16 is arranged on the upper side of the sealing cover 4.

[0027] By setting up the linkage mechanism 16, when stirring and discharging, the linkage mechanism 16 can be pressed down to squeeze the annular frame 10 and the L-shaped scraper 14 to move downward, and overlap with the stirring mechanism 5 through the force plate 13. Then, the stirring mechanism 5 can drive the L-shaped scraper 14 to scrape the inside of the mixing box 3, so as to clean the inner wall of the mixing box 3, thereby reducing the waste caused by excessive material adsorbed by the inner wall of the mixing box 3 after discharging, resulting in subsequent direct cleaning.

[0028] The stirring mechanism 5 includes a driving motor 501 fixedly connected to the upper side of the sealing cover 4, a stirring rod 502 fixedly connected to the output end of the driving motor 501 and located at the lower side of the mixing box 3, and a plurality of stirring blades 503 fixedly connected to the stirring rod 502. The stirring rod 502 drives the stirring blades 503 to rotate to achieve stirring of the concrete.

[0029] like Figure 2 As shown, the linkage mechanism 16 includes a threaded rod 161 threadedly engaged with the upper side of the sealing cover 4, and an extrusion block 162 fixedly connected to the lower end of the threaded rod 161. The extrusion block 162 is driven to move downward by rotating the threaded rod 161, so as to change the position of the annular frame 10.

[0030] The upper end of the threaded rod 161 is fixedly connected with a rotating button 18, and an anti-slip pad 19 is installed on the outer side of the rotating button 18. A circular groove 20 is opened on the lower side of the extrusion block 162, and a rolling ball 21 is rotatably fitted on the inner wall of the circular groove 20. The rolling ball 21 contacts with the upper side of the annular frame 10 to improve the smoothness of the rotation of the annular frame 10.

[0031] like Figure 3As shown, the flipping mechanism 15 is rotatably matched with two hydraulic cylinders 151 on the upper side of the bottom plate 1, and an extension plate 152 is fixedly connected to one side of the mixing box 3 and rotatably matched with the output ends of the two hydraulic cylinders 151. By controlling the side length of the hydraulic cylinders 151, the mixing box 3 can be pushed to flip, thereby realizing the convenience of pouring materials.

[0032] like Figure 3 As shown in the sealing cover 4 , two load-bearing plates 17 in contact with the extension plate 152 are fixedly connected to the upper side of the bottom plate 1 . During the stirring process, the load-bearing plates 17 facilitate supporting the lower side of the extension plate 152 .

[0033] Working principle: When in use, first pour the corresponding raw materials through the feed pipe 6, and then start the driving motor 501 to drive the stirring rod 502 and the stirring blade 503 to rotate and stir the materials to achieve mixing;

[0034] When it is necessary to discharge the material, the discharge valve 7 can be opened, and the material will be discharged from the discharge valve 7 first. When the material remaining on the inner wall of the mixing box 3 is small, the extension plate 152 can be pushed by starting the hydraulic cylinder 151 to push the mixing box 3 to reverse on the inner wall of the U-shaped frame 2, so that the material on the inner wall of the mixing box 3 can flow out faster and more thoroughly.

[0035] When the material on the inner wall is almost poured out, the threaded rod 161 is rotated to push the extrusion block 162 downward, and the annular frame 10 is pushed downward. During the movement, the spring 22 contracts, and the L-shaped scraper 14 and the force plate 13 move downward, so that the force plate 13 overlaps with the uppermost stirring blade 503. Then the drive motor 501 is slowly started to drive the L-shaped scraper 14 to scrape the inner wall, and then the material is discharged by the discharge valve 7, so as to avoid waste caused by subsequent cleaning of the adsorbed material on the inner wall of the mixing box 3, and at the same time improve the cleaning effect of the inner wall of the mixing box 3.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
