Abstract
Description
Technical Field
[0001] This utility model relates to the field of aggregate batching technology, and in particular to an aggregate batching device for a hydraulic engineering station. Background Technology
[0002] A hydraulic mixing plant, also known as a hydraulic engineering station, is a specialized concrete mixing equipment used in water conservancy engineering construction. It primarily produces high-quality concrete, especially in water conservancy projects such as reservoirs, dams, and hydropower stations. Large aggregates used in hydraulic engineering refer to aggregate materials with larger particle sizes used in the construction of hydraulic engineering projects. These aggregates are mainly used in the preparation of concrete and other structural materials and play a crucial role in water conservancy projects. The proportioning of aggregates has a significant impact on the performance of concrete. Proper proportioning can reduce the void volume between aggregates, thereby reducing the amount of cement paste used, saving costs, and improving the workability and durability of the concrete.
[0003] A search revealed Chinese patent application number 202321811514.6, which discloses a mixed aggregate batching device. The device includes an aggregate batching and mixing box with two first grooves on each of its left and right sides. An aggregate mixing trough is located at the top of the box. The bottom of the mixing trough has holes and a discharge port. A pull handle is installed on the side of the discharge baffle. This mixed aggregate batching device has the following drawbacks: it lacks an effective screening device, making it impossible to screen aggregates according to their size. This can easily result in the mixing of aggregates of varying sizes, affecting the proportion of large aggregates. Errors in the proportioning can then impact the actual use of the aggregates. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a large aggregate batching device for hydraulic engineering stations.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A large aggregate batching device for a hydraulic engineering station includes a screening component. The screening component includes a base, a screening chamber on the top outer wall of the base, a feeding port on the top of the screening chamber, and a connecting frame installed on the inner wall of the screening chamber.

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.
[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0024] Example 1
[0025] A large aggregate batching device for a hydraulic engineering station, such as Figure 1-4As shown, the system includes a screening assembly, which includes a base 1. A screening chamber 15 is bolted to the top outer wall of the base 1. A feeding port is opened at the top of the screening chamber 15. A connecting frame 22 is bolted to the inner wall of the screening chamber 15. Multiple sets of connecting frames 22 are symmetrically installed on both sides of the inner wall of the screening chamber 15. A spring damper 21 is bolted to the top outer wall of the connecting frame 22. A screen plate 18 is installed at the top of the spring damper 21. Several sets of vibrators 24 are bolted to the bottom outer wall of the screen plate 18. Two sets of discharge ports are opened on one side of the screening chamber 15. The two sets of discharge ports are located above and below the screen plate 18, respectively. A sealing assembly for facilitating discharge is provided on one side of the screening chamber 15. A batching assembly for configuring large aggregates is provided on one side of the base 1.
[0026] In use, large aggregates can be poured into the screening bin 15 through the feeding port at the top of the screening bin 15 for screening. By starting several sets of vibrators 24, the screen plate 18 can be vibrated. By setting spring dampers 21, the normal vibration of the screen plate 18 is avoided. The vibration of the screen plate 18 causes the large aggregates falling on it to vibrate synchronously. Through vibration, aggregates smaller than the filter hole diameter of the screen plate 18 are screened out, thus completing the screening of large aggregates. After screening, the problem of fine aggregates mixed in with large aggregates can be solved. The screening completes the grading of large aggregates, thus avoiding affecting the proportion of large aggregates during batching. It can ensure the performance and durability when mixed with concrete, and ensure normal operation in actual use.
[0027] The enclosed assembly includes a fixed frame 20, and multiple sets of fixed frames 20 are arranged and installed sequentially on one outer wall of the screening chamber 15. A rotary motor 16 is fixed to one side of the outer wall of the fixed frame 20 by bolts. A rotary shaft 13 is connected to the output end of one side of the rotary motor 16. One end of the rotary shaft 13 is rotatably installed through the fixed frame 20. A sealing baffle 17 is installed at one end of the rotary shaft 13. The installation position and size of the sealing baffle 17 are adapted to the discharge port of the screening chamber 15.
[0028] During use, the two sets of rotating motors 16 control the rotation of the two sets of rotating shafts 13, which in turn control the rotation of the two sets of sealing baffles 17, thereby controlling the opening and closing of the two sets of discharge ports. After screening, the sealing baffle 17 below the screen plate 18 can be opened first, controlling one set of discharge ports to open. After opening, finer aggregates can be collected. After that, the sealing baffle 17 above the screen plate 18 can be opened. By opening the discharge port above the screen plate 18, coarser aggregates can be collected, thus facilitating the discharge. After collection, the sealing baffle 17 is rotated to close the discharge port again, thus avoiding affecting normal screening.
[0029] The batching assembly includes a support rod 3, which is provided in multiple sets and is fixed to the top outer wall of the base 1 by bolts. A batching bin 8 is installed on the top of the support rod 3. A support frame 10 is fixed to the top outer wall of the batching bin 8 by bolts. A speed-regulating motor 11 is installed on the top of the support frame 10. The output end of the speed-regulating motor 11 is connected to a drive shaft 12. One end of the drive shaft 12 is rotatably installed through the support frame 10. Several sets of stirring blades 19 are arranged sequentially on the drive shaft 12. An opening is provided on one side of the batching bin 8. A hinge 9 is installed on one side of the batching bin 8. A discharge gate 7 is installed at one end of the hinge 9. The size and position of the discharge gate 7 are adapted to the opening of the batching bin 8.
[0030] When in use, large aggregates can be added into the batching bin 8. Large aggregates of different coarseness can be added according to the ratio. After the addition is completed, the speed-regulating motor 11 starts to control the drive shaft 12 and the stirring blade 19 to rotate. The addition of large aggregates can be stirred by the rotation of the stirring blade 19. The stirring makes them fully mixed, thus completing the batching of large aggregates. After the batching is completed, the discharge gate 7 is turned to open the opening of the batching bin 8, so as to collect the batched large aggregates. The design of multiple sets of stirring blades 19 can increase the efficiency and effect of stirring.
[0031] For ease of relocation, such as Figure 4 As shown, the bottom outer wall of the base 1 is fixed with casters 2 by bolts, and multiple sets of casters 2 are arranged in sequence.
[0032] When in use, the device can be pushed or pulled to move it. The universal wheels 2 rotate in contact with the ground, which can drive the device to move easily and complete the displacement conveniently.
[0033] To prevent the discharge gate 7 from opening accidentally, such as Figure 1 , 2 As shown, a fixing block 6 is fixedly installed on one side of the outer wall of the batching bin 8 by bolts. An installation shaft 5 is installed on one side of the fixing block 6. A limit frame 4 is rotatably installed at one end of the installation shaft 5. The size and position of the limit frame 4 are adapted to the discharge gate 7.
[0034] During use, a certain amount of damping is provided between the limit frame 4 and the mounting shaft 5 to prevent unnecessary rotation of the limit frame 4. By controlling the rotation of the limit frame 4, it can be limited after the discharge gate 7 is closed, which can effectively prevent the discharge gate 7 from being accidentally opened during batching. When it is necessary to open, the limit frame 4 can be rotated.
[0035] To facilitate the addition of large aggregates, such as Figure 2 , 3 As shown, an auxiliary frame 14 is fixed to the top outer wall of the screening chamber 15 by bolts, and the auxiliary frame 14 gradually expands from bottom to top.
[0036] In use, the size of the top opening of the screening bin 15 can be increased by the auxiliary frame 14 with the opening gradually widening upward, thereby avoiding leakage when large aggregates are poured in due to the small opening. At the same time, the upward-sloping auxiliary frame 14 can play a protective role during vibrating screening, preventing large aggregates from being vibrated out.
[0037] Example 2
[0038] To facilitate the collection of the screened aggregates, refer to Figure 3 , 4 A large aggregate batching device for a hydraulic engineering station. This embodiment makes the following improvements compared to embodiment 1: the bottom inner wall of the screening bin 15 is fixed with a discharge rack 23 by bolts, and the discharge rack 23 is triangular in shape.
[0039] During use, the triangular discharge rack 23 inside the screening bin 15 can assist in the discharge of materials. Its downward slope facilitates the discharge of large aggregates after screening, effectively preventing large aggregates from accumulating inside the screening bin 15.
