Description

Technical Field

[0001] This utility model relates to the field of concrete mixing plant technology, and more specifically, to a metering hopper for a concrete mixing plant with good stability. Background Technology

[0002] The metering hopper is a key component of a concrete batching plant. Its main function is to accurately measure and dispense the various raw materials required for concrete production, such as cement, aggregates (sand and stone), water, and admixtures. This equipment is typically installed on the automated production line of a concrete batching plant and is a crucial link in ensuring the accurate execution of the concrete formula.

[0003] Patent CN215319651U discloses a metering hopper for a concrete mixing plant, including a support, a hopper body on the support, an electric valve at the lower end of the hopper body, baffles on both sides of the hopper body, multiple pressure sensors between the baffles and the support, a feeding port at the upper end of the hopper body, and an air outlet pipe at the upper end of the hopper body. The air outlet pipe extends vertically upward and is equipped with a filter cover extending vertically. The filter cover includes an inner skeleton and a filter mesh surface attached to the outer layer of the skeleton. A drive motor is installed on the outer wall of the upper end of the hopper body, on one side of the air outlet pipe. A connecting spring is installed on the drive motor, one end of which is connected to the output shaft of the drive motor. A rubber vibrating ball for striking the outer wall of the filter cover is installed on the end of the connecting spring away from the drive motor.

[0004] Although the device has many beneficial effects, the following problems still exist: Although the metering hopper can bend by connecting springs so that the rubber vibrating ball can strike the filter cover back and forth, thus facilitating the treatment of attached dust and reducing the possibility of air pipe blockage, the metering hoppers used in traditional concrete mixing plants often face many design challenges. Due to the different physical properties of raw materials, such as the large differences in density and particle size distribution of aggregates (sand, stone), the fluidity and hygroscopicity of cement, and the viscosity of admixtures, these factors directly affect the metering accuracy and stability of the metering hopper.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution:

[0029] A stable measuring hopper for a concrete mixing plant includes four first connecting frames 1, symmetrically distributed, with a third connecting frame 14 fixedly connected between each adjacent first connecting frame 1. Second connecting frames 2 are fixedly connected to the outer surfaces of the four first connecting frames 1, located below the four third connecting frames 14. A measuring hopper body 3 is fixedly connected to the top of the four third connecting frames 14. The measuring hopper body 3 has a conical structure at its bottom, and a bottom plate 15 is fixedly connected to the bottom of the measuring hopper body 3. The bottom plate 15 is hollow and has a splash guard 17 at its bottom. The hopper body also includes:

[0030] The reinforcing component, located on the outer surface of the four first connecting frames 1, is used to enhance the stability of the connection between the metering hopper body 3 and the four first connecting frames 1;

[0031] The protective mounting assembly, located between the four first connecting frames 1, is used to install the splash guard 17 on the bottom of the base plate 15, facilitating the replacement of the splash guard 17. The metering hopper body 3 is supported by four symmetrically distributed first connecting frames 1 and further reinforced by the second connecting frames 2 and the third connecting frames 14, ensuring the stability of the metering hopper during the concrete mixing process.

[0032] Furthermore, the reinforcement components include reinforcing blocks 4, reinforcing blocks 12, and placement slots 13. Reinforcing blocks 4 are fixedly connected between the two first connecting frames 1. The four reinforcing blocks 4 are located between the second connecting frame 2 and the four third connecting frames 14. Placement slots 13 are opened on the outer surfaces of the four reinforcing blocks 4 that are close to each other. Reinforcing blocks 12 are inserted into the interior of the four placement slots 13. The reinforcing blocks 12 are placed in the placement slots 13 on the reinforcing blocks 4, and then fixed by the second bolts 11, which can enhance the connection strength between the first connecting frames 1, thereby improving the overall stability of the metering hopper.

[0033] Furthermore, the outer surfaces of the four reinforcing blocks 4 are all threadedly connected to the corresponding reinforcing blocks 12 with second bolts 11. The four reinforcing blocks 12 are all inclined near the outer surface of the metering hopper body 3. The inclined arrangement of the reinforcing blocks 12 helps to fit with the conical outer surface of the metering hopper body 3.

[0034] Furthermore, the reinforcement components also include reinforcing plates 5 and first bolts 6. The outer surfaces of the four first connecting frames 1 are slidably engaged with reinforcing plates 5, and the outer surfaces of the four reinforcing plates 5 are threaded with multiple first bolts 6. The four reinforcing plates 5 are arranged in a "U" shape. The multiple first bolts 6 pass through the corresponding first connecting frame 1 and are threadedly connected to the metering hopper body 3. The four reinforcing plates 5 are located between the four third connecting frames 14 and the four reinforcing blocks 4. The reinforcing plates 5 are connected to the first connecting frames 1 by the first bolts 6 to form an additional support structure. The "U" shape design of the reinforcing plates 5 not only increases the strength of the connecting frames but also provides a larger support area, further enhancing the stability of the metering hopper.

[0035] Furthermore, the protective mounting assembly includes a handle 7, a threaded rod 8, and a support plate 10. Two symmetrically distributed threaded rods 8 are rotatably connected between the second connecting frame 2 and the reinforcing block 4. The outer surfaces of the two threaded rods 8 are threaded with the support plate 10. Two symmetrically distributed handles 7 are rotatably connected to the bottom of the second connecting frame 2. The two handles 7 are fixedly connected to the corresponding threaded rods 8. By rotating the handles 7, the threaded rods 8 can be driven to rotate.

[0036] Furthermore, two symmetrically distributed guide columns 9 are fixedly connected between the second connecting frame 2 and the reinforcing block 4. The two guide columns 9 are slidably connected to the corresponding support plates 10. Both support plates 10 are arranged in an L-shape. The two support plates 10 are in active contact with the bottom of the splash guard 17, causing the support plates 10 to slide on the guide columns 9.

[0037] Furthermore, an opening and closing plate 16 is slidably connected inside the base plate 15. The opening and closing plate 16 is arranged in an L-shape and is slidably connected inside the base plate 15. When the metering hopper body 3 reaches a certain weight, the opening and closing plate 16 can be opened, thereby allowing the concrete inside the metering hopper body 3 to flow out.

[0038] Working Principle: When workers need to use this stable concrete mixing plant metering hopper, the hopper body 3 is supported by four symmetrically distributed first connecting frames 1, and further reinforced by second connecting frames 2 and third connecting frames 14, ensuring the stability of the metering hopper during concrete mixing. The bottom of the metering hopper body 3 has a conical structure to facilitate the flow of concrete materials. The reinforcing block 12 is placed in the groove 13 on the reinforcing block 4, and then fixed by the second bolt 11, which enhances the connection strength between the first connecting frames 1, thereby improving the overall stability of the metering hopper. The inclined arrangement of the reinforcing block 12 helps to fit with the conical outer surface of the metering hopper body 3, further enhancing the stability of the metering hopper body 3 during use. The reinforcing plate 5 is connected to the first connecting frame 1 by the first bolt 6, forming an additional support structure. The "U"-shaped structure design of the reinforcing plate 5 not only increases the strength of the connecting frame, but also provides greater support. The support area further enhances the stability of the metering hopper. By rotating the handle 7, the threaded rod 8 can be driven to rotate, thereby causing the support plate 10 to slide on the guide column 9. This allows the user to adjust the position of the support plate 10 as needed. The splash guard 17 is placed on the two support plates 10, so that the inner wall of the splash guard 17 contacts the outer surface of the support plate 10. During the movement of the two support plates 10, the splash guard 17 contacts the bottom of the base plate 15. The L-shaped structure design of the support plate 10 enables it to stably support the splash guard 17. The splash guard 17 is used to prevent concrete from splashing out during the outflow process. When necessary, it can be replaced or maintained by rotating the handle 7 in the opposite direction, causing the two support plates 10 to descend, and then the splash guard 17 can be taken out for replacement or cleaning and maintenance. The opening and closing plate 16 is slidably connected to the inside of the base plate 15. When the metering hopper body 3 reaches a certain weight, the opening and closing plate 16 can be opened, thereby allowing the concrete inside the metering hopper body 3 to flow out.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
