[0028] 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.

[0029] Example 1:

[0030] Please see Figures 1-5A concrete aggregate screening device for construction includes a main body 1, a running mechanism, and a replacement mechanism. The running mechanism includes a running frame 2, a first spring 3, a protective box 4, and a vibrator 5. The running frame 2 is mounted on the main body 1 and slidably connected to the main body 1. The first spring 3 is fixedly mounted in the running frame 2, with its other end fixedly connected to the main body 1. The protective box 4 is fixedly mounted on the running frame 2, and the vibrator 5 is fixedly mounted in the protective box 4. The replacement mechanism includes a mounting rod 6, a screen 7, a fixing frame 8, a second spring 9, a fixing bolt 10, and a discharge assembly. The mounting rod 6 is mounted on the main body 1 and rotatably connected to the main body 1. One end of the screen 7 is connected to the mounting rod 6. The fixing frame 8 is mounted on the running frame 2 and slidably connected to the running frame 2. The second spring 9 is fixedly mounted inside the running frame 2, with its other end fixedly connected to the fixing frame 8. The fixing bolt 10 is fixedly mounted on the fixing frame 8.

[0031] In this embodiment, the operating mechanism includes a running frame 2, a first spring 3, a protective box 4, and a vibrator 5. During use, the vibrator 5 installed in the protective box 4 operates, allowing the running frame 2 to slide inside the main body 1. When the running frame 2 shakes up and down, the first spring 3 is compressed. Furthermore, the connecting plate 15 on the running frame 2 slides on the through rod 14, making the sliding of the running frame 2 inside the main body 1 more stable. In order to prevent pressure on the protective box 4 when the running frame 2 slides, the blocking rod 27 at the bottom of the running frame 2 contacts the main body 1 before the protective box 4. Under the action of the first spring 3, the shaking frequency of the running frame 2 is higher.

[0032] In this embodiment, the replacement mechanism includes a mounting rod 6, a screen 7, a fixing frame 8, a second spring 9, fixing bolts 10, and a discharge assembly. In use, the screen 7 is first installed onto the mounting rod 6. The fitting plate 19 on the screen 7 is directly inserted into the mounting hole 18 of the mounting rod 6. When the screen 7 is installed onto the running frame 2, it contacts the placement plate 16, and the other end of the screen 7 directly contacts the running frame 2. The protective plate 20 at one end of the screen 7 also contacts the running frame 2. When the other end of the screen 7 is installed, it can be pulled... The slot 23 at the bottom of the fixed frame 8 allows the fixed frame 8 to slide in the running frame 2 and compress the second spring 9. When the screen 7 is fully installed on the running frame 2, the fixed frame 8 can be released, allowing the compressed second spring 9 to push the fixed frame 8 so that the fixed frame 8 engages with the first locking hole 21 in the screen 7. After the screen 7 is fixed, the fixing bolt 10 can be installed on the fixed frame 8, and the fixing bolt 10 also engages with the threaded hole 22, so that the fixed frame 8 can be fixed to the main body 1.

[0033] In this embodiment, the discharge assembly includes a locking block 11, a third spring 12, and a discharge component 13. In use, the discharge component 13 can be installed on the main body 1. The positioning block 24 on the discharge component 13 is connected to the positioning hole 26 on the main body 1. Pulling the locking block 11 can compress the third spring 12. When it is fully installed on the main body 1, the locking block 11 is released, so that the locking block 11 is connected to the second locking hole 25 on the discharge component 13. This allows the discharge component 13 to be fixed on the main body 1, facilitating the direct discharge of sand and gravel from the running frame 2 to the main body 1. Concrete is discharged from the discharge port 17 of the running frame 2 to the bottom of the main body 1, facilitating the separation of sand and gravel from concrete.

[0034] Example 2:

[0035] In summary, during use, firstly, install the screen 7 onto the running frame 2. The fitting plate 19 on the screen 7 is directly inserted into the mounting hole 18 of the mounting rod 6. When the screen 7 is installed onto the running frame 2, it contacts the placement plate 16, and the other end of the screen 7 directly contacts the running frame 2. The protective plate 20 at one end of the screen 7 also contacts the running frame 2. When the other end of the screen 7 is installed, the pull groove 23 at the bottom of the fixing frame 8 can be pulled, allowing the fixing frame 8 to slide within the running frame 2 and compressing the second spring 9. At this point, the screen 7 is fully installed. When the entire assembly is installed onto the running frame 2, the fixing frame 8 is released, allowing the compressed second spring 9 to push the fixing frame 8 so that it engages with the first locking hole 21 in the screen 7. After the screen 7 is fixed, the fixing bolt 10 can be installed onto the fixing frame 8, and the fixing bolt 10 also engages with the threaded hole 22, thus fixing the fixing frame 8 to the main body 1. Next, the discharge component 13 is installed, and the positioning block 24 on the discharge component 13 engages with the positioning hole 26 on the main body 1. The locking block 11 is then pulled to engage with the screen 13. The third spring 12 can be compressed. When fully installed on the main body 1, the locking block 11 is released, allowing it to engage with the second locking hole 25 on the discharge component 13. This allows the discharge component 13 to be fixed to the main body 1, facilitating the direct discharge of sand and gravel from the running frame 2 to the main body 1. Concrete is discharged from the outlet 17 of the running frame 2 to the bottom of the main body 1, facilitating the separation of sand and gravel from concrete. After the discharge component 13 and the screen 7 are installed, the material can be placed into the screen 7, and the device can be operated. At this time, the vibrator installed in the protective box 4... When device 5 operates, the running frame 2 can slide inside the main body 1. When the running frame 2 shakes up and down, the first spring 3 is compressed. Secondly, the connecting plate 15 on the running frame 2 slides on the through rod 14, making the sliding of the running frame 2 inside the main body 1 more stable. When the running frame 2 slides, in order to prevent pressure on the protective box 4, the blocking rod 27 at the bottom of the running frame 2 contacts the main body 1 before the protective box 4. Under the action of the first spring 3, the shaking frequency of the running frame 2 is higher, resulting in higher separation efficiency of concrete and sand in the material.

[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
