[0001] This utility model relates to the field of sand and gravel production technology, and in particular to a crushing device for sand and gravel production with a dust-proof structure. Background Technology

[0002] Sand and gravel production refers to the process of processing natural ores or construction waste into sand and gravel products that meet the particle size specifications required for construction, road, water conservancy and other engineering projects through a series of physical processing techniques. Sand and gravel production crushing devices with dust-proof structures are equipment specially designed for the crushing process in sand and gravel production. Based on traditional crushing devices, they are special machines that reduce or suppress dust emission during the crushing process by integrating dust-proof structures.

[0003] Existing sand and gravel production crushing equipment with dust-proof structures typically installs filters inside the dust suction pipe or dust suction chamber during use to filter dust. These filters need to be cleaned or replaced regularly to ensure stable filtration. However, the filters in existing technologies are generally fixed inside the pipe with screws, which makes disassembly and cleaning complex and time-consuming, thus affecting the convenience of maintenance and cleaning. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the disassembly and maintenance process of the filter screen is relatively complicated and time-consuming, which will result in low replacement efficiency. To this end, we propose a crushing device for sand and gravel production with a dust-proof structure.

[0005] To achieve the above objectives, this application adopts the following technical solution: a crushing device for sand and gravel production with a dust-proof structure, comprising a fixed support; a crushing component is installed at the top of the fixed support, a hopper is installed at the top of the crushing component, a dust collection component is installed at the rear end of the crushing component, a dust collection chamber is installed at the top of the dust collection component, a dust conveying pipe is installed at the rear end of the dust collection component, the end of the dust conveying pipe is fixedly connected to the top of the dust collection chamber, a replacement groove is provided on one side of the dust collection chamber, and the interior of the replacement groove is slidably connected. The dust collection chamber is equipped with a filter screen. A fixed block is fixedly connected to one side of the dust collection chamber. Traction grooves are opened on both sides inside the fixed block. Traction blocks are slidably connected inside the traction grooves. A toggle plate is fixedly connected between the opposite surfaces of the traction blocks. A locking post is installed at the top of the toggle plate. A locking plate that locks into the locking post is rotatably connected to one side of the fixed block. A limit rod is fixedly connected to the bottom of the toggle plate. A through groove that slidably connects to the limit rod is opened at the bottom of the fixed block. A limit groove that inserts into the limit rod is opened at the top of the filter screen.

[0006] Preferably, the fixed block has a guide groove inside, and a guide block is fixedly connected to one side of the actuating plate, with the inside of the guide groove slidably connected to the guide block.

[0007] Preferably, an energy storage spring is sleeved on the surface of the limiting rod, and the top and bottom ends of the energy storage spring are respectively fixedly connected to the inside of the actuating plate and the fixing block.

[0008] Preferably, the surface of the snap-fit ​​post is fitted with a rubber sleeve.

[0009] Preferably, the front and rear ends of the replacement slot are provided with movable slots, the front and rear ends of the filter screen are fixedly connected with movable blocks, and the interior of the movable slot is slidably connected to the movable blocks.

[0010] Preferably, the surface of the filter screen is coated with an epoxy resin coating.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, when the operator needs to replace the filter screen inside the dust collection chamber, the locking plate is rotated to disengage it from the locking post, thus releasing the fixed actuating plate. The actuating plate is then moved to pull the limiting rod out of the limiting groove, releasing the filter screen. The filter screen can then be pulled out of the dust collection chamber for replacement or cleaning. After completion, the filter screen is slid back into the dust collection chamber through the replacement slot, and the actuating plate is moved again to insert the limiting rod into the limiting groove, securing the filter screen. This facilitates convenient filter screen replacement. When the filter screen becomes clogged with accumulated impurities, the operator only needs to release and move the actuating plate to release the filter screen, enabling convenient cleaning or replacement. This effectively improves the ease of use and maintenance efficiency of the device. Attached Figure Description

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0021] Reference Figures 1-4As shown, this utility model provides a technical solution: a crushing device for sand and gravel production with a dust-proof structure, including a fixed support 1; a crushing component 2 is installed at the top of the fixed support 1, a hopper 3 is installed at the top of the crushing component 2, a dust collection component 4 is installed at the rear end of the crushing component 2, a dust collection chamber 5 is installed at the top of the dust collection component 4, a dust conveying pipe 6 is installed at the rear end of the dust collection component 4, the end of the dust conveying pipe 6 is fixedly connected to the top of the dust collection chamber 5, a replacement groove 7 is opened on one side of the dust collection chamber 5, a filter screen 8 is slidably connected inside the replacement groove 7, a fixed block 9 is fixedly connected to one side of the dust collection chamber 5, traction grooves 10 are opened on both sides inside the fixed block 9, traction blocks 11 are slidably connected inside the traction grooves 10, a lever 12 is fixedly connected between the opposite faces of the traction blocks 11, a locking post 13 is installed at the top of the lever 12, a locking plate 14 that is locked to the locking post 13 is rotatably connected to one side of the fixed block 9, and a limit rod 15 is fixedly connected to the bottom end of the lever 12. The bottom of block 9 has a through groove 16 that slides with the limiting rod 15, and the top of filter 8 has a limiting groove 17 that inserts into the limiting rod 15. When the operator needs to replace the filter 8 inside the dust collection chamber 5, the locking plate 14 is rotated to disengage from the locking post 13, thus releasing the fixed actuating plate 12. Then, the actuating plate 12 is moved to pull the limiting rod 15 out of the limiting groove 17, thus releasing the fixed filter 8. The filter 8 can then be pulled out of the dust collection chamber 5. After replacement or cleaning, the filter screen 8 is slid back into the dust collection chamber 5 through the replacement slot 7, and the actuating plate 12 is moved again to insert the limiting rod 15 into the limiting slot 17 to fix the filter screen 8, thus achieving convenient replacement of the filter screen 8. When the filter screen 8 is clogged with a lot of impurities, the staff only needs to release the fixation of the actuating plate 12 and move it to release the filter screen 8 from the fixed state, thus achieving convenient cleaning or replacement of the filter screen 8, effectively improving the ease of use and maintenance efficiency of the device.

[0022] Reference Figure 5 As shown in this embodiment: a guide groove 18 is provided inside the fixed block 9, and a guide block 19 is fixedly connected to one side of the actuating plate 12. The guide groove 18 is slidably connected to the guide block 19. Through the setting of the guide groove 18 and the guide block 19, the actuating plate 12 can form a stable guiding effect when sliding inside the fixed block 9, so that the limiting rod 15 will not deviate from its movement trajectory when inserted into the limiting groove 17, effectively ensuring the stability of the filter screen 8 fixing process.

[0023] Reference Figure 5As shown in this embodiment: an energy storage spring 20 is sleeved on the surface of the limiting rod 15. The top and bottom ends of the energy storage spring 20 are fixedly connected to the inside of the actuating plate 12 and the fixing block 9, respectively. With the setting of the energy storage spring 20, when the filter screen 8 needs to be removed for replacement or cleaning, the actuating plate 12 is released. At this time, the elastic force stored in the energy storage spring 20 is released, which drives the limiting rod 15 to be pulled out from the inside of the limiting groove 17, thereby achieving quick release of the limit when the filter screen 8 needs to be removed, further improving the operating efficiency.

[0024] Reference Figure 4 As shown in this embodiment: a rubber sleeve 21 is installed on the surface of the snap-fit ​​post 13. By setting the rubber sleeve 21, the snap-fit ​​plate 14 will not shake or shift when snapping with the snap-fit ​​post 13, thereby effectively ensuring the stability of the toggle plate 12 and the limit rod 15 during the fixing process, thereby improving the fixing effect of the filter screen 8.

[0025] Reference Figure 3 As shown in this embodiment: the front and rear ends of the replacement slot 7 are provided with movable slots 22, and the front and rear ends of the filter screen 8 are fixedly connected with movable blocks 23. The interior of the movable slot 22 is slidably connected to the movable block 23. Through the setting of the movable slot 22 and the movable block 23, the filter screen 8 can have a stable limiting effect during the process of pulling out or putting in, thereby making the filter screen 8 more stable and efficient during the installation or removal process, and effectively improving the operational stability.

[0026] Reference Figure 3 As shown in this embodiment, the surface of the filter screen 8 is coated with an epoxy resin coating. By coating the surface of the filter screen 8 with an epoxy resin coating, the surface of the filter screen 8 can have more wear-resistant properties. In this way, when the fine particles in the sand and dust rub against the surface of the filter screen 8, the wear on the surface of the filter screen 8 can be greatly reduced, and the service life of the filter screen 8 can be extended.

[0027] Working principle: When the operator needs to replace the filter 8 inside the dust collection chamber 5, the locking plate 14 is rotated to disengage from the locking post 13, thus releasing the fixed actuating plate 12. The actuating plate 12 is then moved to pull the limiting rod 15 out of the limiting groove 17, releasing the filter 8. The filter 8 can then be pulled out of the dust collection chamber 5 for replacement or cleaning. After completion, the filter 8 is slid back into the dust collection chamber 5 through the replacement groove 7, and the actuating plate 12 is moved again to insert the limiting rod 15 into the limiting groove 17, securing the filter 8. The filter 8 can be easily replaced. When the filter 8 becomes clogged due to excessive impurities, the operator only needs to release and move the actuating plate 12 to remove the filter 8 from its fixed state, enabling convenient cleaning or replacement. This effectively improves the ease of use and maintenance efficiency of the device. The guide groove 18 and guide block 19 provide a stable guide for the actuating plate 12 as it slides within the fixed block 9, preventing the limiting rod 15 from deviating from its trajectory during insertion into the limiting groove 17, thus ensuring the filter 8 remains secure. To ensure stability during the fixing process, the energy storage spring 20 is used. When the filter screen 8 needs to be removed for replacement or cleaning, the actuating plate 12 is released, and the stored elastic force of the energy storage spring 20 is released, causing the limiting rod 15 to be pulled out from the limiting groove 17. This achieves quick release of the limiting position when the filter screen 8 needs to be removed, further improving operational efficiency. The rubber sleeve 21 ensures that the locking plate 14 will not shake or shift when it is locked with the locking post 13, thus effectively ensuring the stability of the actuating plate 12 and the limiting rod 15 during the fixing process. The qualitative design enhances the fixing effect of the filter screen 8. By setting the moving groove 22 and the moving block 23, the filter screen 8 can have a stable limiting effect during the pulling out or putting in process, thereby making the installation or removal of the filter screen 8 more stable and efficient, effectively improving operational stability. By applying an epoxy resin coating to the surface of the filter screen 8, the surface of the filter screen 8 can have more wear-resistant properties, thereby greatly reducing the wear on the surface of the filter screen 8 when fine particles in sand and dust rub against it, and extending the service life of the filter screen 8.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
