[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a high-efficiency raw material conveying mechanism for concrete, comprising a cleaning shell 1, the left and right sides of the inner bottom wall of the cleaning shell 1 are fixedly connected with return springs 3, the top walls of the two return springs 3 are fixedly connected with displacement shells 4, the left and right sides of the bottom wall of the displacement shell 4 are threaded with threaded knobs 5, the tops of the two threaded knobs 5 are threadedly connected with cleaning brushes 6, the left and right sides of the cleaning shell 1 are fixedly connected with connecting blocks 7, the two connecting blocks 7 are fixedly connected with fixed frames 8 on the far sides, the front and rear sides of the two adjacent fixed frames 8 are rotatably connected with belt rollers 9, and the right side of the right fixed frame 8 is fixedly connected with the right side of the right fixed frame 8. A servo motor 10 is fixedly connected, and the output end of the servo motor 10 is fixedly connected to the right side of the front belt roller 9. The outer walls of the two belt rollers 9 are rotatably connected through a conveyor belt 11. A collecting component is arranged on the rear side of the cleaning shell 1, and the collecting component includes a magnet block 12. The front side of the magnet block 12 is fixedly connected to the rear side of the cleaning shell 1, and a collecting shell 13 is arranged on the rear side of the magnet block 12. A magnet slot 14 is opened on the front side of the collecting shell 13, and the rear side of the magnet block 12 is engaged with the magnet slot 14; an iron sheet that is magnetically matched with the magnet block 12 is fixedly connected in the magnet slot 14, and the rear side of the magnet block 12 is magnetically matched with the magnet slot 14.

[0039] Specifically, by starting the servo motor 10, the two belt rollers 9 are driven, and the conveyor belt 11 rotates accordingly, so that the concrete materials can be smoothly transported. Through the clever design of the two reset springs 3, they continuously squeeze the displacement shell 4, so that the cleaning brush 6 installed on the inner wall of the displacement shell 4 through the two threaded knobs 5 fits tightly to the surface of the object to be cleaned. Even if the cleaning brush 6 is worn during use, it can still fit tightly to the surface of the conveyor belt 11 due to the displacement force of the displacement shell 4, thereby increasing the service life of the device. In addition, the continuous movement of the conveyor belt 11 enables the cleaning brush 6 to effectively remove the concrete materials remaining on its surface, reducing the situation where materials are left on the surface of the conveyor belt 11, significantly improving work efficiency, and reducing the burden on staff. This improvement ensures the continuous and efficient operation of the entire conveying system, laying a foundation for improving production efficiency and reducing labor intensity.

[0040] Reference Figure 1 , the top walls of the two fixing frames 8 are fixedly connected with baffles 17;

[0041] Specifically, the two baffles 17 are used to prevent the concrete materials from falling during transportation.

[0042] Reference Figure 1 , Figure 2 and Figure 4 A screening mechanism 2 is provided at the rear side of the right fixed frame 8, and the screening mechanism 2 includes two rotating columns 201, and the sides of the two rotating columns 201 that are far away from each other are respectively fixedly connected to the adjacent sides of the two fixed frames 8, and a screening shell 202 is rotatably connected between the adjacent two rotating columns 201, and the left and right ends of the rear side of the bottom wall of the screening shell 202 are rotatably connected to electric telescopic rods 203, and the output ends of the two electric telescopic rods 203 are rotatably connected to rotating members 204, and the bottom walls of the two rotating members 204 are fixedly connected to support rods 205; a mounting plate 206 is fixedly installed on the rear side of the inner bottom wall of the screening shell 202;

[0043] Specifically, the core part of the device is a screening shell 202, and the concrete material is fed into the screening shell 202 through the conveyor belt 11. The screening shell 202 is designed to have a certain inclination angle, which can speed up the screening rate and improve work efficiency. During the screening process, impurities such as stones are screened out, and concrete materials that meet the requirements can fall to the bottom of the screening shell 202. In order to further optimize the screening effect, we use an electric telescopic rod 203 to adjust the angle of the screening shell 202. By starting the electric telescopic rod 203, the angle of the screening shell 202 is changed through the coordinated action of the rotating part 204 and the support rod 205. This design can not only adjust the screening rate as needed, but also effectively avoid the situation where stones block the screening shell 202. Through the application of this new concrete screening device, we can complete the screening of concrete materials more efficiently and ensure that the quality of concrete meets the requirements, thereby reducing the labor costs of workers and improving work efficiency. The screening shell 202 is formed into a square shell through the fixed installation plate 206, and the screened stones can be collected for unified processing.

[0044] Reference Figure 1 and Figure 4 The front side of the left fixing frame 8 is fixedly connected with a control switch 15, and the control switch 15 is electrically connected to the servo motor 10 and the electric telescopic rod 203 respectively; the front side of the control switch 15 is provided with a protective shell 16, and the left side of the protective shell 16 is rotatably connected to the front side of the left fixing frame 8 through a hinge; the front and rear sides of the bottom of the two fixing frames 8 are fixedly connected with corner pads 18;

[0045] Specifically, through the control switch 15 electrically connected to the servo motor 10 and the electric telescopic rod 203 respectively, the control switch 15 can complete the opening and closing of the device, the protective shell 16 can protect the control switch 15 and prevent accidental touch, and the multiple corner pads 18 can achieve a certain buffering and shock absorption when the device is working.

[0046] Working principle: When starting the conveying work, the front belt roller 9 is driven by starting the servo motor 10, and then the rear belt roller 9 and the conveyor belt 11 complete the rotation, and then the work of conveying concrete materials can be completed. The elastic force of the two return springs 3 can continuously squeeze the displacement shell 4, so that the displacement shell 4 can be displaced after being squeezed under the action of the elastic force, so that the cleaning brush 6 fixed by the two threaded knobs 5 can fit tightly to the surface of the cleaned object. At the same time, even if the cleaning brush 6 is worn and consumed, under the force of the displacement of the displacement shell 4, the cleaning brush 6 can still fit the surface of the conveyor belt 11, so that the service life of the device is improved. Through the movement of the conveyor belt 11, the cleaning brush 6 completes the cleaning of the surface of the conveyor belt 11, which reduces the situation of concrete materials remaining on the surface of the conveyor belt 11, thereby improving The working efficiency is improved, the workload is reduced, and the concrete material is transported into the interior of the screening shell 202 through the conveyor belt 11, so that the device can screen the gravel in the concrete raw material. The screening shell 202 has a certain inclination angle, which speeds up the screening rate. By collecting the concrete material at the bottom of the screening shell 202, the purpose of screening and collecting the concrete material is achieved. By starting the electric telescopic rod 203, under the action of the rotating part 204 and the support rod 205, the angle of the screening shell 202 can be changed, and then the purpose of changing the screening rate can be achieved by changing the inclination angle. At the same time, the situation of gravel blocking the screening shell 202 is reduced, thereby avoiding the quality of the mixed concrete not meeting the requirements and reducing the labor cost of workers. By installing the mounting plate 206, the gravel can be uniformly collected and processed.
