[0017] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] Please see Figure 1 A preferred embodiment of the sieving system of this application includes a protective cover 10, a sieving machine 20 arranged inside the protective cover 10, a weighing device 30 mounted on the protective cover 10, and a calculation module (not shown) connected to the sieving machine 20 and the weighing device 30 by signal connection. The weighing device 30 acquires the weight data of the material after sieving by the sieving machine 20, and the calculation module calculates the weight of the aggregate based on the weight data. In this embodiment, the calculation formula used by the calculation module is: weight of aggregate = weight of (standard sieve + aggregate) - weight of standard sieve, where the weight of (standard sieve + aggregate) is the weight obtained after weighing by the weighing device 30. The weighing device 30 is equipped with a weight sensor, which acquires the weight obtained after weighing, and the weight sensor is connected to the calculation module by signal connection. The protective cover 10 is equipped with a display module 40, and the calculation module is connected to the display module 40 by signal connection. The display module 40 displays the weight of the aggregate calculated by the calculation module. In other embodiments, the calculation module and the display module 40 may also be integrated into a single module, which will not be described in detail here. Furthermore, the calculation module includes a storage unit for storing the calculated weights of the aggregates and correspondingly numbering each aggregate according to its weight. The storage unit employs existing technology, which will not be elaborated upon here.

[0019] The shaking screen machine 20 includes a base 21, a vibration mechanism (not shown) disposed within the base 21, several supports 22 vertically fixed to the base 21, and a positioning component 23 disposed on the supports 22 for positioning. The base and vibration mechanism utilize existing technology. The positioning component 23 includes a fixed plate 231, a floating plate 232 disposed below the fixed plate 231, an elastic element 233 disposed between the fixed plate 231 and the floating plate 232, a locking structure 234 disposed between the floating plate 232 and the fixed plate 231 for locking and unlocking the floating plate 232 and the fixed plate 231, and a locking structure 235 disposed on the supports 22 for fixing the fixed plate 231 to the supports 22. The design of the locking structure 234 and the locking structure 235 makes the installation and disassembly of the positioning component 23 more convenient, and also facilitates the maintenance and upkeep of the shaking screen machine 20.

[0020] It should be noted that this shaking screen system, by placing the shaking screen 20 inside the protective cover 10 and integrating the weighing device 30 and the calculation module, achieves the purpose of directly calculating the mass of the aggregate inside the screen when weighing after shaking screening. In this way, through integrated design, continuous operation of screening and weighing is realized, reducing the steps of manually transferring aggregate, thereby improving the efficiency of aggregate detection. Furthermore, by setting a positioning component 23 on the shaking screen 20, after the screen plate is installed on the shaking screen 20, the elastic element 233 of the positioning component 23 pushes the floating plate 232 to abut against the screen plate (not shown) to apply a certain pressure to the screen plate, thereby improving the clamping effect. Also, due to the presence of the locking structure 235, before installation, the floating plate 232 and the fixed plate 231 are locked by the locking structure 235, so that the elastic element 233 is in a minimum pre-compression state. After the positioning component 23 is installed above the screen plate, the locking structure 235 is unlocked. This facilitates the installation of the positioning component 23 while improving the clamping effect after unlocking. In summary, the shaking screen system of this application can improve the efficiency of aggregate detection and effectively solve the problem of poor screen plate clamping effect.

[0021] In one embodiment, the locking structure 234 includes an insertion block 2341 disposed on the floating plate 232, an insertion groove (not shown) disposed on the fixed plate 231, a locking opening (not shown) formed on the insertion block 2341, and a locking block 2342 disposed on the fixed plate 231. The locking block 2342 is movable on the fixed plate 231 to be inserted into the locking opening. The fixed plate 231 has a T-shaped groove 2311 formed therein. The locking block 2342 includes a base plate and a T-shaped block formed on the base plate. The T-shaped block is inserted into the T-shaped groove 2311, which extends toward the locking opening. A locking tongue is formed on the base plate, and the locking tongue protrudes from the T-shaped block. To prevent the T-shaped block from detaching from the T-shaped slide 2311, the T-shaped slide 2311 is arranged on the side wall of the positioning plate 231 in a 90-degree counterclockwise rotation. Specifically, its horizontal section is arranged on the inner side of the fixing plate 231, and its vertical section is arranged outward.

[0022] To facilitate the mounting of the fixing plate 231 on the bracket 22, the fixing plate 231 is provided with a through hole corresponding to the bracket 22. The locking structure 235 includes an external thread section formed on the bracket 22 and a locking nut threadedly connected to the external thread section.

[0023] In this embodiment, the fixed plate 231 includes a first cylindrical base and three first transverse plates extending outward from the side of the first cylindrical base. Correspondingly, the floating plate 232 includes a second cylindrical base and three second transverse plates extending outward from the side of the second cylindrical base. Elastic elements, specifically springs, are provided between the first and second cylindrical bases and between the first and second transverse plates. The aforementioned locking structure 234 is formed between each of the first and second transverse plates. There are six supports, three of which pass through through holes into the fixed plate 231. To ensure stability, the shaking screen 20 also includes collars 236 fitted onto the six supports. The collars 236 have corresponding holes for the six supports and are positioned above the positioning plate 231. Locking nuts are located above the collars 236.

[0024] The protective cover 10 has a housing space 11 for accommodating the shaking screen machine 20. The protective cover 10 also has a door 12 for opening or closing the housing space 11. In this embodiment, noise-reducing material is provided inside the protective cover 10. An opening element 13 for controlling the start-up of the shaking screen machine 20 is provided on the side wall of the protective cover 10. This design makes the shaking screen machine 20 easy to operate.

[0025] The weighing device 30 is arranged on top of the protective cover 10, and a vibration damping pad (not shown) is provided between the weighing device 30 and the protective cover 10. The integrated design enables continuous operation of screening and weighing, reducing the steps of manually transferring aggregates and thus improving the efficiency of aggregate testing. By providing a vibration damping pad between the weighing device 30 and the protective cover 10, the impact of vibration on the weighing results is reduced, improving the accuracy of weighing.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
