Description

Technical Field

[0001] This utility model relates to the field of block breaking machine technology, and in particular to a quick-release pull-out block breaking machine housing. Background Technology

[0002] A pulverizer is a device that can break hard raw materials or lumps into small particles or powder using mechanical force.

[0003] In existing industrial material handling equipment, the briquetting machine is a key device for processing agglomerated materials. Its core function is to standardize the particle size of materials through a combination of screening and crushing. However, traditional briquetting machines generally suffer from prominent problems in actual operation, such as material accumulation on the screen surface and material stagnation in the gaps between the support columns. As the part that directly contacts the material, the flat or simple arc-shaped structure of the screen causes the material to accumulate around the screen holes. The support column structure located below the screen usually adopts a uniformly arranged cylindrical design, and the right-angle gap area formed between the support column and the bottom surface of the screen becomes a high-incidence area for material stagnation. After long-term operation, the hardened material accumulation not only blocks the screen holes but also causes the screen to deform or even break due to continuous material compression. Although existing technologies have attempted to alleviate material accumulation by increasing the screen hole size or increasing the vibration frequency, the former reduces screening accuracy, and the latter accelerates equipment wear. Neither of these methods fundamentally solves the problem of material retention in the gaps between the screen surface and the support structure, resulting in high equipment maintenance frequency and low operating efficiency, which has become a key technical bottleneck restricting the performance improvement of briquetting machines.

[0004] Therefore, there is an urgent need to provide a quick-release pull-out housing for the shredder to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a quick-release pull-out block breaking machine housing.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a quick-release pull-out block breaking machine housing, including a housing body, two fixed shafts installed inside the housing body, a screen fixedly connected to the outside of the two fixed shafts, and baffles in contact with the screens fixedly connected to both sides of the inner wall of the housing body, and a scraper connected to the top of the screen;

[0007] A drive mechanism for moving the scraper is installed on the outside of the main body of the casing, and a limiting mechanism for limiting the scraper is connected between the scraper and the main body of the casing.

[0008] Multiple arc-shaped fixing blocks that are fixedly connected to the bottom of the screen are fixedly connected to the outside of the two fixed shafts, and multiple sliding plates that are respectively in contact with the fixing blocks are slidably connected to the outside of the two fixed shafts.

[0009] Two of the aforementioned slide plates are connected to the main body of the casing by an elastic mechanism for resetting the slide plates.

[0010] The present invention is further configured such that: a hopper for conveying materials is installed at the bottom of the main body of the casing; a screen is used for screening materials; a fixed shaft is used for supporting the screen; a scraper is used for scraping the screen; a stop block is used to reduce dead corners of accumulation; the fixed block and the sliding plate are arranged at equal intervals; the sliding plate is used for scraping the fixed shaft; a support frame is connected to the bottom of the main body of the casing; and a crusher for breaking up blocks is slidably installed inside the support frame.

[0011] The above technical solution involves crushing lumpy materials with a pulverizer, then screening them through a screen. The crushed particles fall into the bottom hopper and are discharged. The pulverizer on the support frame can slide and adjust its position axially to ensure that the distance between it and the screen adapts to different material characteristics. The screen is supported by a fixed shaft, and a stop block blocks the gap between the screen and the machine body. When the scraper moves, it sweeps and cleans the screen surface, and when the slide plate slides on the fixed shaft, it cleans the gap between the fixed shaft and the screen. The two work together to prevent material from accumulating on the screen surface and the fixed shaft. This layout improves screening efficiency and reduces equipment downtime for cleaning through functional zoning and multi-stage cleaning.

[0012] The present invention is further configured such that: the driving mechanism includes two first brackets respectively fixedly connected to the two outer sides of the main body of the housing, each of the two first brackets is equipped with an electric push rod, the output ends of the two electric push rods are fixedly connected to a moving shaft, the front end of the moving shaft is fixedly connected to two pull rods, the two pull rods pass through the rear end of the main body of the housing and the other end is fixedly connected to the rear end of the scraper.

[0013] Through the above technical solution, the driving mechanism drives the scraper to move. When the screen needs to be cleaned, the electric push rod drives the moving shaft to move, which in turn drives the scraper to move along the screen surface via the pull rod. During the movement of the scraper, its bottom remains in contact with the upper surface of the screen, scraping away the material layer accumulated around the screen holes. The linear motion trajectory of the moving shaft is controlled by the extension and retraction of the electric push rod, ensuring that the scraper covers the entire working area of ​​the screen. This driving method achieves timed or on-demand cleaning through automated control, avoiding manual intervention. At the same time, the thrust of the electric push rod can be adjusted to adapt to the adhesion characteristics of different materials, keeping the screen continuously unobstructed.

[0014] The present invention is further configured such that: the limiting mechanism includes a plurality of second brackets fixedly connected to the front end of the bottom of the main body of the casing, and each of the plurality of second brackets has a shaft fixedly connected inside it, and the plurality of shafts pass through the scraper and the other end is fixedly connected to the rear end of the inner wall of the main body of the casing.

[0015] Through the above technical solution, the function of the limiting mechanism is to limit and guide the scraper. When the scraper moves, shaft two acts as a guide shaft through the scraper, and the second bracket fixes the position of shaft two, ensuring that the scraper can only move linearly along the axial direction. The clearance fit between shaft two and the scraper restricts its degree of freedom and prevents the scraper from deflecting during movement. This limiting structure ensures uniform contact pressure between the scraper and the screen through physical constraints, avoiding incomplete cleaning or screen scratches caused by scraper tilting, improving the cleaning effect while protecting the equipment structure.

[0016] The present invention is further configured such that: the plurality of sliders are divided into two groups and correspond to two fixed shafts respectively; the bottom of the two groups of sliders are respectively fixedly connected to a pull shaft; the two pull shafts pass through the rear end of the main body of the housing; and the other end of the two pull shafts is fixedly connected to a handle; the handle is used to pull the slide plate to move.

[0017] With the above technical solution, when it is necessary to clean the fixed shaft, pull the handle to move the shaft, causing the slide plate to slide along the fixed shaft. When the slide plate moves, it contacts the surface of the fixed shaft, pushing out the material stuck on the fixed shaft. The two sets of slide plates correspond to the two fixed shafts respectively, and complete cleaning is achieved by pulling synchronously. After the slide plate slides into place, release the handle, and the spring force of the elastic mechanism will make the slide plate automatically return to its original position. This operation is manually triggered and uses the relative movement between the slide plate and the fixed shaft to clear the gap and avoid the risk of material accumulation caused by material hardening.

[0018] The present invention is further configured such that: the elastic mechanism includes two third brackets fixedly connected to the bottom sides of the inner wall of the main body of the housing, and each of the two third brackets is fixedly connected to a shaft three that is fixedly connected to the rear end of the inner wall of the main body of the housing. The bottom of each of the two slide plates is fixedly connected to a plate two. The two shaft three passes through the two plates two respectively. A spring is sleeved on the outside of each of the two shaft three. The two ends of the spring are fixedly connected to the rear end of the plate two and the rear end of the inner wall of the main body of the housing respectively.

[0019] Through the above technical solution, the function of the elastic mechanism is to drive the skateboard to automatically reset; when the skateboard slides, the second plate moves along the third axis and compresses the spring; when the external force is removed, the elastic potential energy of the spring is released, pushing the second plate to drive the skateboard back to the initial position; the third axis, as a guide axis, ensures the stability of the skateboard's movement trajectory, and the preload of the spring keeps the skateboard in contact with the fixed plate when it is not in operation; this elastic reset mechanism realizes the automatic return of the skateboard through energy storage and release, ensuring that the skateboard can return to the effective working position after each cleaning and maintaining continuous cleaning capability.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model achieves automatic scraping of accumulated material on the screen surface through a scraper and a drive mechanism, avoiding screen hole blockage; the limiting mechanism ensures linear movement of the scraper, maintaining uniform contact with the screen and preventing incomplete cleaning or screen scratches; the sliding plate and elastic mechanism enable manual ejection and automatic reset of stuck material on the fixed shaft, preventing material hardening and jamming.

[0022] 2. This utility model reduces the dead angle of material accumulation between the screen and the main body of the machine by using a stop block, further reducing the risk of material accumulation; the position of the crusher can be adjusted by sliding to adapt to different material characteristics and improve screening efficiency; the coordinated action of each mechanism effectively solves the problems of material accumulation on the screen surface and material stagnation in the gaps of the support structure in traditional crushers, reduces the frequency of equipment maintenance, improves operating efficiency, and extends the service life of the screen.

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0033] Please see Figures 1-8 This embodiment of a quick-release pull-out shredder housing includes a housing body 1. Two fixed shafts 2 are installed inside the housing body 1. A screen 3 is fixedly connected to the outside of the two fixed shafts 2. Stops 4 that contact the screen 3 are fixedly connected to both sides of the inner wall of the housing body 1. A scraper 5 is connected to the top of the screen 3. A drive mechanism 6 for driving the scraper 5 is installed outside the housing body 1. The drive mechanism 6 includes two first brackets 601 fixedly connected to both sides of the outside of the housing body 1. An electric push rod 602 is installed inside each of the two first brackets 601. A moving shaft 603 is fixedly connected to the output end of each of the two electric push rods 602. Two pull rods 604 are fixedly connected to the front end of each moving shaft 603, and the two pull rods 604 pass through... The rear end of the main body 1 and the other end are fixedly connected to the rear end of the scraper 5. The function of the drive mechanism 6 is to drive the scraper 5 to move. When it is necessary to clean the screen 3, the electric push rod 602 drives the moving shaft 603 to move, and the pull rod 604 drives the scraper 5 to move along the surface of the screen 3. During the movement of the scraper 5, its bottom keeps in contact with the upper surface of the screen 3, scraping off the material layer accumulated around the screen holes. The linear motion trajectory of the moving shaft 603 is controlled by the extension and retraction of the electric push rod 602 to ensure that the scraper 5 covers the entire working area of ​​the screen 3. This drive method realizes timed or on-demand cleaning through automatic control, avoiding manual intervention. At the same time, the thrust of the electric push rod 602 can be adjusted to adapt to different material adhesion characteristics and keep the screen 3 continuously unobstructed.

[0034] like Figure 3 As shown, a limiting mechanism 7 for limiting the scraper 5 is connected between the scraper 5 and the main body 1. The limiting mechanism 7 includes multiple second brackets 701 fixedly connected to the bottom front end of the main body 1. Each of the multiple second brackets 701 has a shaft 702 fixedly connected inside it. The shafts 702 pass through the scraper 5 and are fixedly connected at their other ends to the rear end of the inner wall of the main body 1. The function of the limiting mechanism 7 is to limit and guide the scraper 5. When the scraper 5 moves, the shafts 702 act as guide shafts through the scraper 5. The second brackets 701 fix the position of the shafts 702, ensuring that the scraper 5 can only move linearly along the axial direction. The clearance fit between the shafts 702 and the scraper 5 restricts its degree of freedom and prevents the scraper 5 from deflecting during movement. This limiting structure ensures uniform contact pressure between the scraper 5 and the screen 3 through physical constraints, avoiding incomplete cleaning or scratches on the screen 3 caused by the tilting of the scraper 5, improving the cleaning effect while protecting the equipment structure.

[0035] like Figures 4-6As shown, multiple sliders are divided into two groups, each corresponding to one of the two fixed shafts 2. The bottom of each group of sliders is fixedly connected to a pull shaft 703. The two pull shafts 703 pass through the rear end of the main body 1, and the other end of each pull shaft 703 is fixedly connected to a handle 704. The handle 704 is used to pull the slide plate 9. When cleaning the fixed shaft 2 is required, pulling the handle 704 moves the pull shaft 703, causing the slide plate 9 to slide along the fixed shaft 2. When the slide plate 9 moves, it contacts the surface of the fixed shaft 2, pushing out the material stuck on the fixed shaft 2. The two groups of slide plates 9 correspond to the two fixed shafts 2 respectively, achieving comprehensive cleaning through synchronous pulling. After the slide plate 9 slides to its position, releasing the handle 704 causes the spring force of the elastic mechanism 10 to automatically reset the slide plate 9. This operation is manually triggered, utilizing the relative movement between the slide plate 9 and the fixed shaft 2 to clear the gap and avoid the risk of material accumulation caused by material hardening.

[0036] like Figures 4-5 As shown, multiple arc-shaped fixing blocks 8 are fixedly connected to the outside of the two fixed shafts 2 and fixedly connected to the bottom of the screen 3. Multiple sliding plates 9 are slidably connected to the outside of the two fixed shafts 2, each in contact with the fixing blocks 8. An elastic mechanism 10 for driving the sliding plates 9 to reset is connected between the two sliding plates 9 and the main body 1. The elastic mechanism 10 includes two third brackets 1001 fixedly connected to the bottom sides of the inner wall of the main body 1. A shaft 1002 fixedly connected to the rear end of the inner wall of the main body 1 is fixedly connected to the inside of each of the two third brackets 1001. A plate 1003 is fixedly connected to the bottom of each of the two sliding plates 9. The two shafts 1002 pass through the two plates 1003 respectively. A spring 10 is sleeved on the outside of each of the two shafts 1002. 04. The two ends of spring 1004 are fixedly connected to the rear end of plate 2 1003 and the rear end of the inner wall of the main body 1, respectively. The function of elastic mechanism 10 is to drive the slide plate 9 to automatically reset. When the slide plate 9 slides, plate 2 1003 moves along shaft 3 1002 and compresses spring 1004. When the external force is removed, the elastic potential energy of spring 1004 is released, pushing plate 2 1003 to drive slide plate 9 back to the initial position. Shaft 3 1002 serves as a guide shaft to ensure the stability of the movement trajectory of slide plate 9. The preload of spring 1004 keeps slide plate 9 in contact with fixed block 8 when not in operation. This elastic reset mechanism realizes the automatic return of slide plate 9 through energy storage and release, ensuring that slide plate 9 can return to the effective working position after each cleaning and maintain continuous cleaning capability.

[0037] like Figures 1-8As shown, a hopper 11 for conveying materials is installed at the bottom of the main body 1 of the machine casing. A screen 3 is used to screen materials. A fixed shaft 2 is used to support the screen 3. A scraper 5 is used to scrape the screen 3. A stop block 4 is used to reduce dead corners of accumulation. Fixed blocks 8 and sliding plates 9 are arranged at equal intervals. The sliding plate 9 is used to scrape the fixed shaft 2. A support frame 12 is connected to the bottom of the main body 1 of the machine casing. A crusher 13 for breaking up blocks is slidably installed inside the support frame 12. The crusher 13 breaks up the blocky materials, which are then screened by the screen 3. The crushed particles fall into the bottom hopper 1. 1. Discharge; The crusher 13 on the support frame 12 can slide and adjust its position along the axis to ensure that the distance between it and the screen 3 is adapted to different material characteristics; The screen 3 is supported by the fixed shaft 2, and the stop block 4 blocks the gap between the screen 3 and the machine body 1; When the scraper 5 moves, it scrapes and cleans the surface of the screen 3, and when the slide plate 9 slides on the fixed shaft 2, it cleans the gap of the fixed shaft 2. The two work together to prevent the material from accumulating on the surface of the screen 3 and the fixed shaft 2; This layout improves screening efficiency and reduces equipment downtime for cleaning through functional zoning and multi-level cleaning.

[0038] In use, when cleaning the screen 3 is required, the electric push rod 602 drives the moving shaft 603 to move, and the pull rod 604 drives the scraper 5 to move linearly along the surface of the screen 3. The bottom of the scraper 5 keeps in contact with the upper surface of the screen 3, scraping away the material layer accumulated around the screen holes. The linear trajectory of the moving shaft 603 is controlled by the extension and retraction of the electric push rod 602 to ensure that the scraper 5 covers the entire working area of ​​the screen 3. On the other hand, the handle 704 can be manually pulled to move the pull shaft 703, causing the slide plate 9 to slide along the fixed shaft 2. The slide plate 9 contacts the surface of the fixed shaft 2, thus removing the material stuck on the fixed shaft 2. After the material is pushed out and the handle 704 is released, the spring 1004 pushes the slide plate 9 along the shaft 1002 to automatically return to the initial position through the plate 2 1003; the block 4 on the inner wall of the main body 1 reduces the dead corner of accumulation between the screen 3 and the main body 1; the crusher 13 on the support frame 12 slides and adjusts its position to crush the blocky material; the crushed material is screened by the screen 3, and the particles fall into the bottom hopper 11 for discharge; the scraper 5 and the slide plate 9 work together to clean the stuck material on the surface of the screen 3 and the fixed shaft 2 respectively, so as to avoid the material hardening and clogging the screen holes or squeezing and deforming the screen 3, and maintain the continuous and efficient operation of the equipment.
