Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a vibrating screen with an easy-to-disassemble and assemble screen mesh. Background Technology

[0002] A mine is an independent production and operation unit with a certain scale and mining boundaries that extracts ore. They play a vital role in resource development and economic production. A mine typically includes one or more mining workshops responsible for the extraction and preliminary processing of ore. In addition, mines also have auxiliary workshops, such as maintenance and storage facilities, to support the main mining operations. A ore processing plant is usually closely connected to the mine; its main function is to process and sort the extracted ore to improve its grade and recovery rate.

[0003] Vibrating screens are important raw material screening devices in mineral sand production, used to screen and collect large-volume and small-volume mineral sands. For example, Chinese Patent Publication No. CN221515181 U discloses "a mining vibrating screen that is easy to disassemble and assemble". Through the cooperation of knobs, threaded rods and internal threaded fixing tubes, the position of the connecting plate can be fixed, thereby fixing the position of the movable plate and the triangular pressure plate. In turn, the triangular pressure plate fixes the position of the screen plate. The triangular pressure plate fixes the position of the screen plate without affecting the screening of ore. The two opposing fixing components are used to fix the same screen plate. When disassembling the screen plate, only the two triangular pressure plates need to be removed, which makes it easy for workers to quickly disassemble and assemble the screen plate.

[0004] However, in actual use, the triangular pressure plate is easily deformed by the impact of ore after long-term use, making it difficult to remove and affecting the efficiency of disassembly and assembly. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as the triangular pressure plate being easily deformed by the impact of ore, making it difficult to remove the triangular pressure plate and affecting the disassembly and assembly efficiency. Therefore, this invention proposes a vibrating screen that facilitates the disassembly and assembly of the screen mesh.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a vibrating screen with easy-to-assemble and disassemble screen, including a support frame, a mounting frame connected to the support frame via a connecting structure, a drive structure that cooperates with the mounting frame on the support frame, a screen inside the mounting frame, a baffle rotatably connected to one side of the mounting frame via an L-shaped frame, a slot opened in the mounting frame, the screen movably inserting into the slot, the baffle contacting the screen, a discharge port on one side of the mounting frame, and a fixing structure that cooperates with the baffle on the mounting frame.

[0008] Furthermore, the fixing structure includes a fixing frame, and the mounting frame has a mounting groove that mates with the fixing frame.

[0009] Furthermore, a rotating shaft is fixedly installed in the mounting groove, the rotating shaft is rotatably connected to the fixing frame, and a torsion spring is provided between the rotating shaft and the fixing frame.

[0010] Furthermore, the fixing frame includes a plug-in part that is rotatably connected to the rotating shaft and a limiting part that connects with the baffle, and a connecting plate is provided between the limiting part and the plug-in part.

[0011] Furthermore, the connecting plate is threaded with a hand-tightening bolt, and the baffle is provided with a threaded hole corresponding to the baffle.

[0012] Furthermore, a support rod is fixedly installed inside the mounting frame, and the upper end of the support rod is in contact with the screen.

[0013] The vibrating screen proposed in this utility model, which facilitates the assembly and disassembly of the screen mesh, has the following advantages:

[0014] In this utility model, the screen is initially fixed by setting a slot, making the connection between it and the mounting frame more stable. The position of the screen is restricted by setting a baffle to prevent it from separating from the mounting frame and falling off.

[0015] Secondly, in this utility model, the baffle is limited and fixed by setting a fixed frame and a baffle to prevent the baffle from opening when the vibrating screen is in use. A torsion spring is set to prevent the fixed frame from loosening or misaligning. A hand-tightened bolt is set to form an integral structure between the fixed frame and the baffle, which is more solid and stable. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A vibrating screen with an easy-to-assemble and disassemble screen includes a support frame 1. The support frame 1 is connected to an mounting frame 3 via a connecting structure 2. The support frame 1 is provided with a drive structure that cooperates with the mounting frame 3. A screen 4 is installed inside the mounting frame 3. A baffle 5 is rotatably connected to one side of the mounting frame 3 via an L-shaped frame. The L-shaped frame and the baffle 5 are rotatably connected via a rotating shaft. When the baffle 5 needs to be opened, it is opened by rotating along the rotating shaft of the L-shaped frame. A slot 31 is provided inside the mounting frame 3. The screen 4 is movably inserted into the slot 31. The baffle 5 is in contact with the screen 4. A discharge port 6 is provided on one side of the mounting frame 3. A fixing structure 7 that cooperates with the baffle 5 is provided on the mounting frame 3.

[0023] In this utility model, the screen 4 is initially fixed by the slot 31, making its connection with the mounting frame 3 more stable. The position of the screen 4 is restricted by the baffle 5 to prevent it from separating from the mounting frame 3. The baffle 5 is limited and fixed by the fixing structure 7 in cooperation with the baffle 5 to prevent the baffle 5 from opening when the vibrating screen is in use.

[0024] Furthermore, in this embodiment, the fixing structure 7 includes a fixing frame 71, and the mounting frame 3 is provided with a mounting groove 72 that cooperates with the fixing frame 71. The fixing frame 71 contacts the baffle 5 under the action of gravity and limits the position of the baffle 5.

[0025] Furthermore, in this embodiment, a rotating shaft 73 is fixedly installed in the mounting groove 72. The rotating shaft 73 is rotatably connected to the fixing frame 71. A torsion spring 74 is provided between the rotating shaft 73 and the fixing frame 71. The torsion spring 74 applies force to the fixing frame 71, making it in close contact with the baffle 5, so as to prevent the fixing frame 71 from loosening or misaligning.

[0026] It should be noted that, in this embodiment, the fixing frame 71 includes a plug-in part 711 rotatably connected to the rotating shaft 73 and a limiting part 712 that connects with the baffle 5. A connecting plate 713 is provided between the limiting part 712 and the plug-in part 711, forming an L-shaped structure between the limiting part 712 and the connecting plate 713, and an L-shaped structure between the connecting plate 713 and the plug-in part 711. When the baffle 5 tends to rotate and open, the connecting plate 713 is pulled to make it move, but it cannot move under the action of the plug-in part 711 and the rotating shaft, thereby fixing the baffle 5.

[0027] Furthermore, in this embodiment, a hand-tightening bolt 75 is threaded onto the connecting plate 713, and a threaded hole corresponding to the baffle 5 is provided on the baffle 5. By rotating the hand-tightening bolt 75, it is inserted into the threaded hole on the baffle 5, thereby forming an integral structure with the fixing bracket 71 and the baffle 5, which is more solid and stable.

[0028] More specifically, in some embodiments, a support rod 8 is fixedly installed inside the mounting frame 3. The upper end of the support rod 8 contacts the screen 4 to support the screen 4 and prevent the screen 4 from deforming too much after long-term use and becoming difficult to remove.

[0029] Working method: During operation, the screen 4 is initially fixed by the slot 31 to make the connection between it and the mounting frame 3 more stable. The position of the screen 4 is restricted by the baffle 5 to prevent it from separating from the mounting frame 3. The fixing frame 71 contacts the baffle 5 to limit the position of the baffle 5. When the baffle 5 tends to rotate and open, the connecting plate 713 is pulled to make it move, but it cannot move under the action of the insertion part 711 and the rotating shaft, thus fixing the baffle 5.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
