Technical Field

[0001] This utility model relates to the field of screening machine technology, and in particular to a drum sand screening machine. Background Technology

[0002] Traditional screens are usually fixed with a large number of bolts. When the screen needs to be replaced, the operator has to spend a lot of time and effort to unscrew each bolt. This is not only cumbersome, but also inefficient, which greatly affects the continuous operation time of the equipment and increases the equipment maintenance cost and downtime losses.

[0003] Therefore, this application provides a drum sand screening machine to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a drum sand screening machine, which aims to solve the problem that traditional screens are usually fixed with a large number of bolts, and when the screen needs to be replaced, the operator has to spend a lot of time and effort to unscrew many bolts one by one, which is cumbersome.

[0006] Preferably, the screening assembly includes a screen, a primary fixing component, a secondary fixing component, a plug-in component, and an overlapping component. The primary fixing component and the secondary fixing component are detachably installed on both ends of the screen. A plug-in component is provided on the outer wall of the primary fixing component. The plug-in component is rotatably connected to the connecting rod through a C-shaped groove at its end.

[0007] The outer wall of the secondary fastener is provided with an overlapping member, and the outer wall of the overlapping member is provided with a C-shaped groove and overlaps with another set of connecting rods;

[0008] Furthermore, the connection between the secondary fixing component and the support rod is detachable.

[0009] Preferably, a slot is provided on the end face of the screen, and a primary locking strip and a secondary locking strip adapted to the slot are provided on the end face of the primary fixing member and the secondary fixing member, respectively.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] This invention, through a unique screening component design, utilizes the cooperation of primary and secondary fixing components with the slots and strips of the screen, as well as the connection methods of plug-in and overlapping components with the connecting rods. Combined with the fixing bolts and nuts in the limiting component, it changes the traditional method of fixing the screen entirely with bolts. When replacing the screen, simply unscrew the nuts to release the limiting of the overlapping components, allowing for quick disassembly and installation of the screen. This significantly improves screen replacement efficiency, saves considerable time and labor costs, reduces equipment downtime, and enhances equipment operational continuity and production efficiency. The screen disassembly and assembly process requires no complex tools or cumbersome operating procedures, allowing operators to easily complete the task, greatly reducing labor intensity, minimizing the risk of errors due to complex operations, improving operational safety and accuracy, and making equipment maintenance easier and more convenient.

[0020] 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.

[0021] Example: Reference Figure 1-4 The illustrated rotary sand screening machine includes a fixed plate 1 and a drive shaft 2. Three sets of fixed plates 1 are connected by support rods 3. The drive shaft 2 is connected to the fixed plate 1 by a support rod. Two sets of adjacent fixed plates 1 (outer walls) are connected by a screening assembly 7. A connecting rod 4 is provided on the fixed plate 1 (the position of the connecting rod 4 corresponds one-to-one with the position of the support rod 3, with the support rod 3 located inside and the connecting rod 4 located outside). The screening assembly 7 is hinged to the connecting rod 4, and the free end of the screening assembly 7 is detachably connected to the support rod 3.

[0022] As one embodiment of this example, the screening component 7: In order to facilitate the disassembly and assembly of the screen 8, a primary fixing member 9 and a secondary fixing member 11 are detachably installed on both ends of the screen 8, respectively. A connector 10 is provided on the outer wall of the primary fixing member 9, and the connector 10 is rotatably connected to the connecting rod 4 through the C-shaped groove at the end.

[0023] The outer wall of the secondary fastener 11 is provided with an overlapping member 12, and the outer wall of the overlapping member 12 is provided with a C-shaped groove and overlaps on another set of connecting rods 4;

[0024] Furthermore, the secondary fixing component 11 and the support rod 3 are detachably connected.

[0025] As one embodiment of this invention, slots 800 are provided on the end face of the screen 8, and primary locking strips 900 and secondary locking strips 1100 adapted to the slots 800 are provided on the end faces of the primary fixing member 9 and the secondary fixing member 11, respectively, thereby realizing the assembly of the screening component 7.

[0026] As one embodiment of this example, the overlapping member 12 is provided with a through hole 1200, which is connected to the support rod 3 through a limiting component.

[0027] As one implementation method in this embodiment, the limiting component includes a fixing bolt 5 and a nut 6. The fixing bolt 5 is installed on the support rod 3, and the through hole 1200 is adapted to the fixing bolt 5. Then, the nut 6 is threaded onto the fixing bolt 5. The nut 6 is used to press the overlapping piece 12 to achieve fixation. Compared with the original method of using bolts to install and fix the screen 8, this method is convenient, quick, time-saving and labor-saving.

[0028] The working principle of this practical application is as follows: When the screen 8 needs to be replaced after long-term use, unscrew the nut 6 on the fixing bolt 5 to release the limit on the overlapping part 12. Then, with the connecting rod 4 where the plug-in part 10 is located as the center, pry the screen 8 outward to separate the overlapping part 12 from the other set of connecting rods 4. The through hole 1200 separates from the fixing bolt 5. Then, slide the screen 8 in one direction to separate the slot 800 from the first-level locking strip 900. Then, slide the second-level locking strip 1100 out of the other set of slots 800 to remove the screen 8. Connect the slot 800 on the new screen 8 with the first-level locking strip 900 and the second-level locking strip 1100. Then, assemble the entire screening assembly 7 through the first-level fixing part 9 and the second-level fixing part 11. Rotate around the connecting rod 4 as the center to make the overlapping part 12 re-overlap with the other set of connecting rods 4. The fixing bolt 5 passes through the through hole 1200 and is tightened with the nut 6 to complete the replacement operation.
