[0029] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0030] like Figures 1 to 6 As shown, This utility model provides a split-branch type casting hopper, including a distributor 1, a distributor screen 2, a fine aggregate guide box 4, and a coarse aggregate guide box 5;
[0031] The material distributor 1 includes a material distribution shell 101 and a coarse aggregate discharge port 102. The material distribution screen 2 is installed inside the material distributor 1. The material distribution screen 2 is designed as an arch shape with an upward convex side. The material distribution screen 2 is used to screen the concrete. Fine aggregates no larger than 15mm can pass through the material distribution screen 2 and enter the fine aggregate guide box 4. Therefore, the mesh size of the material distribution screen 2 is slightly smaller than or equal to 15mm. The material distribution screen 2 includes a high point and a low point. The interval between the low point and the material distribution shell 101 is the coarse aggregate discharge port 102. The coarse aggregates enter the coarse aggregate guide box 5 from the coarse aggregate discharge port 102. The particle size of the coarse aggregates is greater than 15mm.
[0032] Specifically, the material distribution screen 2 divides the concrete into fine aggregate with a particle size of less than or equal to 15 mm and coarse aggregate with a particle size greater than 15 mm. The fine aggregate passes through the mesh of the material distribution screen 2 and enters the fine aggregate guide box 4, while the coarse aggregate enters the coarse aggregate guide box 5 from the coarse aggregate discharge port 102. The fine aggregate is used to pour into the outer 60 mm of the CL mesh frame plate, that is, the fine aggregate enters the protective layer 60 mm outside the insulation board, while the coarse aggregate is used to pour into the inner 200 mm of the CL mesh frame plate, that is, the coarse aggregate enters the structural layer 200 mm inside the insulation board.
[0033] To allow concrete to pass through the distribution screen 2, a top cover 3 is installed on the top of the distributor 1. The top cover 3 includes a cover body 301 and a concrete inlet 302. The cover body 301 covers the top of the distributor 1, and the concrete inlet 302 is located directly above the middle part of the distributor 1 and directly above the highest point of the distribution screen 2. With the top cover 3 installed on the top of the distributor 1, concrete enters the interior of the distributor 1 through the concrete inlet 302 and falls into the middle of the distribution screen 2. The concrete moves along the distribution screen 2 and is eventually separated into coarse aggregate and fine aggregate, which are discharged from the coarse aggregate discharge port 102 and the mesh of the distribution screen 2, respectively. This maximizes the screening of the concrete and prevents fine aggregate from being discharged directly from the coarse aggregate discharge port 102 without passing through the mesh.
[0034] It should be noted that the mesh of the material distribution screen 2 is connected to the fine aggregate guide box 4, and the concrete inlet 302 is connected to the coarse aggregate guide box 5. The fine aggregate guide box 4 includes a fine aggregate box body 401 and a fine aggregate outlet 402.
[0035] To improve the ease of moving the device, a movable frame 6 is provided on the lower side of the fine aggregate guide box 4 and the coarse aggregate guide box 5. The bottom of the fine aggregate guide box 4 is inclined downwards, and the bottom of the coarse aggregate guide box 5 is inclined downwards. The movable frame 6 is equipped with caster assemblies.
[0036] In order to allow coarse and fine aggregates to be poured at the same time, the distance between the outlet of the coarse aggregate guide box 5 and the fine aggregate outlet 402 of the fine aggregate guide box 4 needs to be adjusted according to the actual situation. Specifically, an outer guide tube 7 is provided on the lower side of the fine aggregate box 401. The angle of inclination of the outer guide tube 7 to the lower side is equal to or greater than the angle of inclination of the fine aggregate box 401 to the lower side. In this way, after the fine aggregate enters the outer guide tube 7, it will continue to move downward along the guide tube 8.
[0037] More specifically, a guide tube 8 is inserted inside the outer guide tube 7, the outer guide tube 7 and the guide tube 8 are slidably connected, and the guide tube 8 is installed on the fine aggregate box 401. A movable plate 9 is installed inside the outer guide tube 7, and a limiting plate 10 is provided on the guide tube 8 at the position corresponding to the movable plate 9. The limiting plate 10 is used to limit the movement distance of the movable plate 9 and the outer guide tube 7 to prevent the outer guide tube 7 from completely separating from the fine aggregate box 401.
[0038] It should be noted that the outer guide tube 7 is connected to an adjustment unit 11. The adjustment unit 11 is used to adjust the distance between the outer guide tube 7 and the fine aggregate outlet 402. The adjustment unit 11 includes a first connecting plate 1101, a second connecting plate 1102, and a telescopic rod 1103. The first connecting plate 1101 is movably installed on the outer guide tube 7. The first connecting plate 1101 and the second connecting plate 1102 are movably connected through a rotating shaft. The second connecting plate 1102 is movably connected to the fine aggregate box 401. The rotating shaft is movably connected to the output end of the telescopic rod 1103.
[0039] When the telescopic rod 1103 is activated, it can push the outer guide tube 7 through the first connecting plate 1101 and the second connecting plate 1102 to move along the guide tube 8, adjust the position of the outlet of the outer guide tube 7, and thus adjust the final outlet position of the fine aggregate to adapt to the outlet of the coarse aggregate guide box 5. In this way, the coarse aggregate and fine aggregate can be poured at the same time.
[0040] In summary, the present invention provides a split-type pouring hopper, in which the internal distribution screen 2 divides the concrete into fine aggregate with a particle size less than or equal to 15mm and coarse aggregate with a particle size greater than 15mm. The fine aggregate passes through the mesh of the distribution screen 2 and enters the fine aggregate guide box 4, while the coarse aggregate enters the coarse aggregate guide box 5 from the coarse aggregate discharge port 102. The fine aggregate is used for pouring to the outer 60mm of the CL mesh frame plate, that is, the fine aggregate enters the protective layer of the outer 60mm of the insulation board, while the coarse aggregate is used for pouring to the inner 200mm of the CL mesh frame plate, that is, the coarse aggregate enters the structural layer of the inner 200mm of the insulation board. By dividing the concrete into coarse and fine aggregates and pouring them separately to two areas, the advantages and disadvantages of coarse and fine aggregates can be fully utilized, and the insulation board formed after pouring has better insulation performance.
[0041] When the telescopic rod 1103 is activated, it can push the outer guide tube 7 through the first connecting plate 1101 and the second connecting plate 1102 to move along the guide tube 8, adjust the position of the outlet of the outer guide tube 7, and thus adjust the final outlet position of the fine aggregate, so that it can adjust its position according to the outlet position of the coarse aggregate guide box 5, and can simultaneously carry out the pouring work of coarse aggregate and fine aggregate.
[0042] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
