[0002] A concrete batching plant, also known as a commercial concrete plant or concrete mixing plant, is a complete set of equipment for centralized concrete mixing. Its core function is to mix raw materials such as cement, sand, gravel, and water in precise proportions to produce concrete that meets engineering requirements. However, during the process of feeding and batching aggregates at a concrete batching plant, the aggregates produced after crushing recycled concrete are often reused. Since these aggregates often contain small particles or fine materials that do not meet the particle size requirements, if these unqualified aggregates are included in subsequent production steps, they will seriously affect the quality of the concrete.

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.

[0021] Example 1:

[0022] Please see Figures 1-4 As shown, this utility model provides an aggregate feeding and batching mixing plant based on a concrete mixing plant, including a screening box 3 and a concrete mixer 1. A belt conveyor 6 is fixedly installed between the lower right end of the outer surface of the screening box 3 and the upper left end of the concrete mixer 1. A guide platform 5 is fixedly connected to the left end of the top of the screening box 3. A screen plate 4 is movably connected to the middle end of the screening box 3. Fixing frames 8 are fixedly connected to both sides of the screen plate 4. A fixing rod 10 is fixedly connected to the right end of the fixing frame 8. A rotating wheel 18 is movably connected to the two fixing rods 10 near each other through a bearing. A working box 9 is fixedly connected to the middle end of the outer surface of the screening box 3. A drive motor 12 is fixedly installed on the right side of the outer surface of the working box 9. A first bevel gear 13 is fixedly installed at the output end of the drive motor 12. A second bevel gear 14 meshes with the surface of the first bevel gear 13. A rotating shaft 15 is fixedly installed at the middle end of the second bevel gear 14. Turntables 16 are fixedly connected to both ends of the rotating shaft 15.

[0023] In this technical solution, the guide platform 5 is used to collect the aggregate falling from the bucket of the loader, allowing it to fall down the inclined plane onto the screen plate 4. As the aggregate rolls down the inclined plane of the screen plate 4, the screen plate 4 can remove small particles mixed in with the aggregate. Under the action of the belt conveyor 6, the aggregate after screening from the screening box 3 can be transported from left to right into the hopper of the concrete mixer 1. At the same time, through the configuration of the drive motor 12, the first bevel gear 13, the second bevel gear 14, the rotating shaft 15, the turntable 16, the rotating wheel 18, the fixed rod 10, the fixed frame 8, and the screen plate 4, the screen plate 4 can more quickly remove small particles from the aggregate under the action of movement, effectively improving the effect of removing small particles from the aggregate. Thus, under the overall coordination, the effect of removing small particles mixed in with the aggregate during the aggregate feeding and batching process in the concrete mixing plant is achieved, effectively ensuring the quality of subsequent concrete production.

[0024] It should be noted that, firstly, the concrete mixer 1, as existing technology, is used in the concrete batching plant for the thorough mixing of concrete raw materials, and weighing sensors are installed around the concrete mixer 1 and between the surrounding support frame to weigh the aggregates added inside during the feeding and batching process; secondly, during the process of conveying aggregates from bottom to top, the belt conveyor 6 has baffles installed on its surface to ensure that the aggregates can be conveyed and fed normally.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, guide sleeves 19 are fixedly connected to both sides of the working box 9. The inner cavity of the guide sleeve 19 is movably connected to the guide wheel 20 through the bearing. The surface of the guide wheel 20 is movably connected to the surface of the fixed rod 10. The lower end of the inner cavity of the screening box 3 is fixedly connected to the guide frame 7. The left end of the bottom of the screen plate 4 is movably connected to the left end of the top of the guide frame 7. The bottom of the outer surface of the screening box 3 is fixedly connected to the support base plate 2. The bottom of the belt conveyor 6 is fixedly installed on the right end of the top of the support base plate 2. The two sides of the rotating shaft 15 are movably connected to the support plate 17 through the bearing. The right side of the support plate 17 is fixedly connected to the right side of the inner cavity of the working box 9. The right end of the fixed frame 8 is fixedly connected to the left side of the fixed rod 10. The turntable 16 is inclined. The left end of the turntable 16 is movably connected to the surface of the rotating wheel 18.

[0027] In this technical solution, the guide sleeve 19 and guide wheel 20 are used to guide the fixed rod 10, reducing the probability of the fixed rod 10 tilting due to force. The guide frame 7 is used to guide the small particles falling from the screening box 3. The support base plate 2 is used to support the bottom of the screening box 3 and the belt conveyor 6. The support plate 17 is used to support both sides of the rotating shaft 15, preventing the rotating shaft 15 from tilting due to force.

[0028] The working principle of this utility model is as follows: the guide platform 5 can collect the aggregate falling from the bucket of the loader, and allow the aggregate to fall down the inclined plane onto the screen plate 4. While rolling down the inclined plane of the screen plate 4, the screen plate 4 can screen out small particles mixed in with the aggregate. Under the action of the belt conveyor 6, the aggregate after screening in the screening box 3 can be transported from left to right into the hopper of the concrete mixer 1. At the same time, by starting the drive motor 12, the first bevel gear 13 can be driven to rotate. The rotation of the first bevel gear 13 can drive the second bevel gear 14, the rotating shaft 15 and the turntable 16 to rotate. While the turntable 16 is rotating, it can push the rotating wheel 18, the fixed rod 10, the fixed frame 8 and the screen plate 4 to reciprocate along the through holes on both sides of the screening box 3. Under the action of the screen plate 4, the small particles in the aggregate can be screened out more quickly, effectively improving the screening effect of small particles in the aggregate.

[0029] 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.
