Technical Field
[0001] This utility model relates to the field of concrete mix proportioning technology, specifically a quantitative device for large-volume concrete mix proportioning. Background Technology
[0002] Different projects have different requirements for concrete strength (such as C20, C30, etc.). Therefore, it is necessary to adjust the ratio of cement, aggregate, and water to precisely control the compressive strength after hardening and ensure structural safety. Hence, a mix proportioning device is needed to mix concrete.
[0003] For example, patent CN212948434U discloses a concrete quantitative proportioning device for building construction. It includes a concrete proportioning mechanism, a concrete mixing mechanism, a concrete discharging mechanism, a mixing tank, mixing pipes, a mixing motor, a mixing shaft, and spiral mixing blades. This device achieves quantitative mixing of cement and aggregate, ensuring stable concrete quality. The concrete discharging mechanism allows for different discharging methods to suit various construction conditions and adapt to different construction sites.
[0004] The concrete quantitative proportioning device proposed in the aforementioned patent works by adding concrete material into a proportioning box, and then using a motor installed in the proportioning box to drive a conveyor belt to feed the material. This setup results in a fast material feeding speed, but the amount of material falling cannot be controlled, making it inconvenient to use.
[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content
[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a quantitative device for large-volume concrete mix design, which solves the problem that the concrete material is fed at a fast speed, the amount of material falling cannot be controlled, and the device is inconvenient to use.
[0007] The technical solution adopted by this application to solve its technical problem is: a quantitative device for large-volume concrete proportioning, including a mounting base plate and a support frame fixedly installed on the upper part of the mounting base plate. A mixing box is fixedly installed on the upper part of the mounting base plate. A first motor is fixedly installed on one end of the outer wall of the mixing box. A stirring rod is installed on the output end of the first motor. A discharge pipe is fixedly installed on the lower end of one side of the outer wall of the mixing box. When the discharge pipe is not in use, it is sealed by a sealing plug. The first motor drives the stirring rod to mix the material accumulated in the mixing box evenly. Feeding components are fixedly installed on both sides of the upper end of the support frame. The feeding components are set to be suitable for quantitatively discharging the material to be proportioned.
[0008] The feeding assembly includes a receiving mechanism and a filtering mechanism in the inner cavity of the receiving mechanism connected by a thread. The filtering mechanism is used to filter impurities in the material entering the inner cavity of the receiving mechanism. A discharge mechanism is installed at the bottom of the inner cavity of the receiving mechanism to discharge the material evenly.
[0009] Furthermore, the housing mechanism includes a housing and a fixed frame fixedly installed in the middle of the inner wall of the housing.
[0010] Furthermore, threaded rods are fixedly installed at the four corners of the upper end of the fixed frame, and a material discharge groove is opened in the middle of the bottom surface of the housing.
[0011] Furthermore, the filtration mechanism includes a filter screen and circular grooves formed at the four upper corners of the filter screen. The filter screen is configured to filter material impurities entering the inner cavity of the housing.
[0012] Furthermore, the material discharge mechanism includes a second motor and a first limiting plate installed at the output end of the second motor, with a fixed shaft fixedly installed at one end of the first limiting plate.
[0013] Furthermore, multiple partitions are fixedly installed in a circular pattern at equal intervals around the outer wall of the fixed shaft, and a second limiting disc is fixedly installed at the other end of the fixed shaft.
[0014] The beneficial effects of this application are as follows: This application provides a quantitative device for the proportioning of large-volume concrete. By adding the material into the inner cavity of the housing, the material will be filtered by the filtration mechanism and injected into the upper end of the fixed shaft and the partition. At this time, the second motor is started to drive the first limiting plate, the fixed shaft, the partition and the second limiting plate to rotate. Since the partition is circular and fixedly installed on the outer wall of the fixed shaft at equal intervals, when the fixed shaft drives the partition to rotate, the partition will cause the material to be fed in a uniform and quantitative manner.

[0025] like Figure 1 As shown, a quantitative device for mass concrete mix proportioning includes a mounting base plate 1 and a support frame 2 fixedly mounted on the upper end of the mounting base plate 1. A mixing chamber 3 is fixedly mounted on the upper end of the mounting base plate 1. A first motor 4 is fixedly mounted on one end of the outer wall of the mixing chamber 3. A stirring rod 5 is mounted on the output end of the first motor 4. A discharge pipe 6 is fixedly mounted on the lower end of one side of the outer wall of the mixing chamber 3. When not in use, the discharge pipe 6 is sealed with a sealing plug. The first motor 4 drives the stirring rod 5 to mix the materials accumulated in the mixing chamber 3 evenly. Feeding components 7 are fixedly mounted on both sides of the upper end of the support frame 2. The feeding components 7 are set to be suitable for quantitatively discharging the materials to be proportioned.
[0026] like Figure 2As shown, the feeding assembly 7 includes a receiving mechanism 71 and a filtering mechanism 72 threadedly connected to the inner cavity of the upper end of the receiving mechanism 71. The filtering mechanism 72 is configured to filter material impurities entering the inner cavity of the receiving mechanism 71. A discharge mechanism 73 is installed at the bottom of the inner cavity of the receiving mechanism 71. The discharge mechanism 73 is configured to discharge the material evenly.
[0027] like Figure 3 As shown, the material discharge mechanism 73 includes a second motor 731 and a first limiting plate 732 installed at the output end of the second motor 731. A fixed shaft 733 is fixedly installed at one end of the first limiting plate 732.
[0028] Multiple partitions 734 are fixedly installed in a circular pattern at equal intervals around the outer wall of the fixed shaft 733, and a second limiting plate 735 is fixedly installed at the other end of the fixed shaft 733. The second motor 731 drives the first limiting plate 732, the fixed shaft 733, the partitions 734 and the second limiting plate 735 to rotate together, wherein one end of the second limiting plate 735 is movably installed through a movable shaft and the side wall of the feed chute 714.
[0029] In this application, by adding material into the inner cavity of the housing 711, the material is filtered by the filter mechanism 72 and then injected into the upper end of the fixed shaft 733 and the partition 734. At this time, the second motor 731 is started to drive the first limiting plate 732, the fixed shaft 733, the partition 734 and the second limiting plate 735 to rotate. Since the partition 734 is fixedly installed on the outer wall of the fixed shaft 733 in a circular shape with equal spacing, when the fixed shaft 733 drives the partition 734 to rotate, the partition 734 will drive the material to be fed evenly and quantitatively.
[0030] like Figure 2 As shown, the housing mechanism 71 includes a housing 711 and a fixed frame 712 fixedly installed in the middle of the inner wall of the housing 711.

[0032] like Figure 3 As shown, the filter mechanism 72 includes a filter screen plate 721 and circular grooves 722 formed at the four corners of the upper end of the filter screen plate 721. The threaded rod 713 is movably installed in the inner cavity of the circular groove 722 and is fixed by a nut. The filter screen plate 721 is designed to filter impurities that enter the inner cavity of the housing 711.
[0033] In this application, after the material enters the upper part of the filter plate 721, the filter installed on the upper part of the filter plate 721 will screen out impurities and larger material pieces in the material. This setting facilitates the partition plate 734 to discharge the material better. At the same time, the filter plate 721 can be removed from the upper part of the fixed frame 712 by rotating the nut from the outer surface of the threaded rod 713, so as to clean the filter plate 721. It is convenient to use.
[0034] In summary: By cooperating with the housing 711, the filter mechanism 72, the fixed shaft 733, the partition 734, the second motor 731, and the second limit plate 735, the partition 734 drives the material to be fed evenly and quantitatively. By cooperating with the filter screen 721, the threaded rod 713, and the fixed frame 712, the filter screen 721 can be removed from the top of the fixed frame 712 for cleaning.
