[0002] A concrete batching plant, also known as a commercial concrete plant or concrete mixing plant, is a complete set of equipment for centralized mixing of concrete. Its core function is to mix raw materials such as cement, sand, gravel, and water in a precise ratio to produce concrete that meets the requirements of the project. Currently, concrete batching plants usually require conveying equipment to transport the produced concrete to transport vehicles.
[0003] However, the concrete conveying equipment used in current batching plants is usually a fixed structure. Since the height of the tank inlet of the transport vehicles produced by different manufacturers often varies, the fixed conveying equipment cannot be adjusted according to the height of the tank inlet. As a result, the concrete is prone to splashing due to the large drop during the conveying process, which not only wastes materials but also increases the difficulty of cleaning up afterward.

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.
[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0022] Example 1:
[0023] Please see Figures 1-4 As shown, this utility model provides a concrete conveying device suitable for a mixing plant, including a shaftless screw conveyor 1 and a concrete silo 2. A hopper 8 is fixedly connected to the left end of the top of the shaftless screw conveyor 1, and a fixed frame 22 is fixedly connected to the right end of the top of the shaftless screw conveyor 1. Both sides of the fixed frame 22 are provided with through slots 5. An installation frame 7 is fixedly installed at the lower right end of the concrete silo 2. A support plate 19 is fixedly connected to the lower right end of the installation frame 7. A fixed box 11 is fixedly connected to the upper right end of the installation frame 7. A drive motor 12 is fixedly installed on the right side of the outer surface of the fixed box 11. A first bevel gear 13 is fixedly installed at the output end of the drive motor 12. An adjusting screw 17 is movably connected between the left end of the bottom of the fixed box 11 and the left end of the top of the support plate 19 through a bearing. A second bevel gear 15 is fixedly installed at the top of the adjusting screw 17. A moving plate 21 is threadedly connected to the middle end of the adjusting screw 17. A T-shaped rod 6 is fixedly connected to the right end of the bottom of the moving plate 21.
[0024] In this technical solution, the hopper 8 is designed to collect the concrete discharged from the bottom of the concrete silo 2 via the discharge valve during concrete conveying. During the operation of the shaftless screw conveyor 1, the concrete inside the hopper 8 is conveyed to the right and falls into the transport vehicle through the discharge port on the right. Simultaneously, the drive motor 12, first bevel gear 13, second bevel gear 15, adjusting screw 17, moving plate 21, T-shaped rod 6, through groove 5, and fixed frame 22 allow operators to easily adjust the height of the discharge port on the right side of the shaftless screw conveyor 1 according to the height of the transport vehicle's inlet. This effectively prevents concrete from splashing due to large drop during conveying, greatly meeting the usage requirements of the concrete mixing plant.
[0025] It should be noted that, firstly, the concrete silo 2 in the concrete mixing plant can be used to temporarily buffer the concrete mixed by the concrete mixer, effectively solving the problem of time difference in the scheduling of transport vehicles; secondly, the shaftless screw conveyor 1, as existing technology, is a continuous conveying device that uses the rotation of the screw blades to push materials. During the concrete conveying process, the screw blades can be driven by a motor to rotate, thereby pushing the concrete to move and be conveyed.
[0026] Example 2:
[0027] Based on Embodiment 1, this utility model is as follows: Figures 1-4As shown, a second corrugated telescopic sleeve 18 is fixedly sleeved between the bottom left end of the movable plate 21 and the top left end of the support plate 19. Both ends of the second corrugated telescopic sleeve 18 are fixedly fitted with second metal clamps. A first corrugated telescopic sleeve 16 is fixedly sleeved between the top left end of the movable plate 21 and the bottom left end of the outer surface of the fixed box 11. Both ends of the first corrugated telescopic sleeve 16 are fixedly fitted with first metal clamps. A guide rod 20 is fixedly connected between the top middle end of the support plate 19 and the bottom middle end of the outer surface of the fixed box 11. The middle end of the movable plate 21 is slidably connected to the middle end of the guide rod 20. Both sides of the hopper 8... A support shaft 9 is fixedly connected, and a support frame 10 is movably connected to the surface of the support shaft 9 via a bearing. The top of the support frame 10 is fixedly installed at the bottom of the concrete silo 2. Support columns 3 are fixedly connected to the four sides of the lower end of the concrete silo 2. A base plate 4 is fixedly connected between the bottoms of the four support columns 3. A stabilizing shaft 14 is fixedly installed on the left side of the first bevel gear 13. The left side of the stabilizing shaft 14 is movably connected to the left side of the inner cavity of the fixed box 11 via a bearing. The first bevel gear 13 meshes with the second bevel gear 15. The lower end of the T-shaped rod 6 is slidably connected to the surface of the through groove 5, and the upper end of the T-shaped rod 6 is slidably connected to the right end of the support plate 19.
[0028] In this technical solution, the first corrugated telescopic sleeve 16 and the second corrugated telescopic sleeve 18 effectively protect the area around the adjusting screw 17 from dust, preventing dust from adhering and affecting the normal use of the adjusting screw 17. The guide slide rod 20 supports and guides the moving plate 21, preventing it from rotating or tilting during movement. The support shaft 9 and support frame 10 support the left end of the hopper 8 and the shaftless screw conveyor 1. The support column 3 and the base plate 4 support the bottom of the concrete silo 2. The stabilizing shaft 14 supports the left side of the first bevel gear 13, preventing it from tilting due to force.
[0029] The working principle of this utility model is as follows: By setting up the hopper 8, the concrete discharged from the bottom of the concrete silo 2 through the discharge valve can be collected during the concrete conveying process. During the operation of the shaftless screw conveyor 1, the concrete inside the hopper 8 can be conveyed to the right and fall into the transport vehicle through the discharge port at the right end. When it is necessary to adjust the conveying height of the shaftless screw conveyor 1 according to the height of the inlet of the transport vehicle, the drive motor 12 is started by the external controller, which drives the first bevel gear 13 to rotate. The rotation of the first bevel gear 13 drives the second bevel gear 15 and the adjusting screw 17 to rotate. The rotation of the adjusting screw 17 can drive the moving plate 21 and the T-shaped rod 6 to move. At the same time, the T-shaped rod 6 can drive the fixed frame 22 and the right end of the shaftless screw conveyor 1 to move through the through groove 5, so that the staff can easily adjust the height of the right end discharge port of the shaftless screw conveyor 1 according to the height of the inlet of the transport vehicle.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
