Description

Technical Field

[0001] This utility model relates to the field of pulverizer technology, and in particular to a modular pulverizer. Background Technology

[0002] Existing crushers typically employ an integrated design, and their internal crushing components (such as blades and rollers) are prone to wear or blockage after long-term use, requiring maintenance or replacement.

[0003] However, traditional crushers have a fixed structure, and the disassembly and cleaning process is complex, often requiring professional personnel, which is time-consuming and labor-intensive. In addition, the connection between the feed hopper and the crushing chamber is mostly fixed, making it difficult to quickly open or flip them when cleaning residual materials or maintaining internal components, resulting in low maintenance efficiency.

[0004] Therefore, there is an urgent need for a modular, easily disassembled crusher structure that can simplify the maintenance process and improve the ease of use of the equipment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the fixed structure of traditional crushers, the complex disassembly and cleaning process, which often requires professional personnel and is time-consuming and labor-intensive. In addition, the connection between the feed hopper and the crushing chamber is mostly fixed, making it difficult to quickly open or flip when cleaning residual materials or maintaining internal components, resulting in low maintenance efficiency. Therefore, this invention proposes a modular crusher.

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

[0007] A modular crusher includes a frame, a lower crushing box fixedly connected to the top of the frame, a discharge hopper fixedly connected to the inner wall of the top of the frame, the discharge hopper being connected to the bottom of the lower crushing box, an upper crushing box being rotatably connected to the top of the lower crushing box via a first connecting assembly, and a set of crushing components for crushing materials being provided between the upper and lower crushing boxes.

[0008] The top of the upper crushing box is rotatably connected to a feeding hopper via a second connecting assembly. The feeding hopper is connected to the upper crushing box. An upper limit block is fixedly connected to one side of the feeding hopper, and a lower limit block is fixedly connected to one side of the upper crushing box. The lower limit block is equipped with a limiting component for limiting the upper limit block.

[0009] In one possible design, the first connecting assembly includes a groove formed on one side of the lower crushing chamber, with rotating rods rotatably connected to the inner walls of both sides of the groove, and second connecting plates fixedly sleeved on the outer walls of the rotating rods, with one side of each of the two second connecting plates fixedly connected to one side of the upper crushing chamber.

[0010] In one possible design, the crushing assembly includes a crushing roller rotatably connected between an upper crushing chamber and a lower crushing chamber. A servo motor is fixedly connected to the top of the frame, and the output shaft of the servo motor is fixedly connected to one end of the crushing roller. Two sets of crushing blades arranged in a ring are fixedly fitted on the outer wall of the crushing roller, with two blades in each set. Two symmetrically arranged semi-circular support boxes are fixedly connected to the inner wall of the lower crushing chamber, and the semi-circular support boxes cooperate with the crushing blades. Multiple fixed blades are fixedly connected to the inner walls of both sides of the upper crushing chamber. Multiple fixed protrusions are fixedly connected to the outer wall of the crushing roller, and the fixed blades cooperate with the fixed protrusions.

[0011] In one possible design, the second connecting assembly includes a first connecting plate fixedly connected to one side of the feed hopper, a fixing frame fixedly connected to one side of the upper crushing box, a common rotating shaft rotatably connected between the inner walls of the two sides of the fixing frame, and the first connecting plate fixedly sleeved on the outer wall of the rotating shaft.

[0012] In one possible design, the limiting component includes a second strip-shaped hole on one side of the lower limiting block, a first strip-shaped hole inside the upper limiting block, two symmetrically arranged circular grooves at one end of the lower limiting block, a fixed rod slidingly passing through the interior of the circular groove, a common push plate fixedly connected to one end of the two fixed rods, a rectangular plate fixedly connected to one side of the push plate, the rectangular plate slidably connected inside the second strip-shaped hole, a locking rod fixedly connected to the top of the rectangular plate, the locking rod cooperating with the first strip-shaped hole, a circular block fixedly connected to the top of the locking rod, the circular block being located at the top of the upper limiting block and used to limit the upper limiting block.

[0013] In one possible design, the lower limit block, the fixing rod, and the rectangular plate are all provided with slots inside, and the same pin is inserted into the multiple slots. The pin is used to brake the fixing rod and the rectangular plate.

[0014] In one possible design, two symmetrically arranged hooks are fixedly connected to one side of the upper crushing box, and two symmetrically arranged buckles are fixedly connected to one side of the lower crushing box. The hooks and buckles are used together to connect the upper crushing box and the lower crushing box, and a handle is fixedly connected to one side of the upper crushing box.

[0015] In one possible design, the top of the feeding hopper is fixedly connected to a feeding hopper, and an observation window is fixedly connected to one side of the top of the feeding hopper.

[0016] In this application, during use, the material is fed into the inside of the feeding bin through the feeding hopper, and then enters the inside of the upper crushing box and the lower crushing box for crushing. The servo motor is started, and the output shaft of the servo motor drives the crushing roller to rotate. The crushing roller drives the crushing blade and multiple fixed protrusions to rotate. The crushing blade rotates inside the semi-circular support box, while the fixed protrusions and fixed blades continuously squeeze the material inside. The qualified material is discharged into the inside of the discharge hopper through the bottom of the lower crushing box.

[0017] When the device needs cleaning and maintenance, the pin can be pulled out first. At this time, the pin will no longer brake the fixed rod and the rectangular plate. Pull out the push plate, which will drive the fixed rod and the rectangular plate to pull out. The rectangular plate will drive the clamping rod and the round block to move laterally, so that the clamping rod moves out of the inside of the first strip hole. The top of the round block will no longer abut against the top of the upper limit block. The feed bin can be flipped from one side. The feed bin will drive the first connecting plate to rotate around the rotating shaft. The feed bin can be rotated to one side, so that the material stuck inside the upper crushing box can be cleaned.

[0018] When the crushing roller needs to be replaced or maintained, the latch can be pried open to disengage the hook and latch, thus separating the lower crushing box from the upper crushing box. The upper crushing box can then be rotated by the handle, and the second connecting plate can be rotated around the rotating rod, allowing the upper crushing box to open to one side of the lower crushing box. This allows the crushing roller to be removed, facilitating its replacement or maintenance. Installation and disassembly are more convenient, significantly reducing the working time of the staff.

[0019] Beneficial effects: Modular design facilitates maintenance: The upper crushing box, lower crushing box, and feed hopper can be flipped together through the first and second connecting components, allowing the equipment to be opened quickly for easy cleaning of internal residual materials or replacement of crushing components.

[0020] Quick-release crushing roller: The upper crushing box can be easily flipped open by using a hook and a large-mouth snap-fit ​​method, combined with the rotating structure of the rotating rod and the second connecting plate, making it convenient to replace or maintain the crushing roller.

[0021] The feed hopper can be flipped for easy cleaning: Through the cooperation of the limiting components (clamp, round block and pin), the fixed state of the feed hopper can be quickly released, allowing it to flip around the rotating axis, making it easy to clean the blocked material.

[0022] High-efficiency crushing structure: The crushing blades on the crushing roller cooperate with the semi-circular support box, and the fixed protrusion and fixed blade form a shearing action to improve crushing efficiency.

[0023] Easy to operate and reduces maintenance time: The use of detachable limiting structures such as pins and push plates makes maintenance without complicated tools, greatly reducing downtime and improving production efficiency. Attached Figure Description

[0030] 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.

[0031] Example 1

[0032] Reference Figure 1-5A pulverizer includes: a frame 1, a lower pulverizing box 6 fixedly connected to the top of the frame 1, a discharge hopper 2 fixedly connected to the inner wall of the top of the frame 1, the discharge hopper 2 communicating with the lower part of the lower pulverizing box 6, and an upper pulverizing box 5 rotatably connected to the top of the lower pulverizing box 6 via a first connecting assembly. The first connecting assembly includes a groove 13 formed on one side of the lower pulverizing box 6, rotating rods 21 rotatably connected to the inner walls of both sides of the groove 13, and second connecting plates 12 fixedly sleeved on the outer walls of the rotating rods 21. One side of each of the two second connecting plates 12 is fixedly connected to one side of the upper pulverizing box 5. When it is necessary to replace or maintain the pulverizer... When roller 22 is in operation, buckle 16 can be pried open to disengage hook 15 from buckle 16, thus separating the lower crushing box 6 and the upper crushing box 5. The upper crushing box 5 can then be rotated using handle 14, causing the second connecting plate 12 to rotate around rotating rod 21. This allows the upper crushing box 5 to open to one side of the lower crushing box 6, enabling the removal of crushing roller 22 for easy replacement or maintenance. Installation and disassembly are more convenient, significantly reducing worker time. A common set of crushing components for crushing materials is provided between the upper crushing box 5 and the lower crushing box 6. The machine includes a crushing roller 22, which is rotatably connected between the upper crushing box 5 and the lower crushing box 6. A servo motor 3 is fixedly connected to the top of the frame 1, and the output shaft of the servo motor 3 is fixedly connected to one end of the crushing roller 22. Two sets of crushing blades 23 arranged in a ring are fixedly sleeved on the outer wall of the crushing roller 22, with two blades 23 in each set. Two symmetrically arranged semi-circular support boxes 20 are fixedly connected to the inner wall of the lower crushing box 6. The semi-circular support boxes 20 are used in conjunction with the crushing blades 23. Multiple fixed blades 19 are fixedly connected to the inner walls of both sides of the upper crushing box 5. The fixed connection has multiple fixed protrusions 24. The fixed blade 19 works in conjunction with the fixed protrusions 24 to feed the material into the feed bin 4 through the feed hopper 7, and then into the upper crushing box 5 and the lower crushing box 6 for crushing. The servo motor 3 is started, and the output shaft of the servo motor 3 drives the crushing roller 22 to rotate. The crushing roller 22 drives the crushing blade 23 and multiple fixed protrusions 24 to rotate. The crushing blade 23 rotates inside the semi-arc support box 20. At the same time, the fixed protrusions 24 and the fixed blade 19 continuously squeeze the material inside. The qualified material is discharged into the discharge hopper 2 through the bottom of the lower crushing box 6.

[0033] The top of the upper crushing box 5 is rotatably connected to the feed hopper 4 via a second connecting assembly. The second connecting assembly includes a first connecting plate 9 fixedly connected to one side of the feed hopper 4. A fixing frame 11 is fixedly connected to one side of the upper crushing box 5. The same rotating shaft 10 is rotatably connected between the inner walls of both sides of the fixing frame 11. The first connecting plate 9 is fixedly sleeved on the outer wall of the rotating shaft 10. The feed hopper 4 is connected to the upper crushing box 5. An upper limit block 17 is fixedly connected to one side of the feed hopper 4. A lower limit block 18 is fixedly connected to one side of the upper crushing box 5. The lower limit block 18 has a limiting component inside for limiting the upper limit block 17. The limiting component includes a second strip hole 34 opened on one side of the lower limit block 18. A first strip hole 25 is opened inside the upper limit block 17. Two symmetrically arranged circular grooves 33 are opened at one end of the lower limit block 18. A fixing rod 28 slides through the inside of the circular grooves 33. The same push plate 30 is fixedly connected to one end of the two fixing rods 28. A fixed part is fixedly connected to one side of the push plate 30. A rectangular plate 29 is slidably connected inside the second strip-shaped hole 34. A locking rod 31 is fixedly connected to the top of the rectangular plate 29. The locking rod 31 cooperates with the first strip-shaped hole 25. A circular block 32 is fixedly connected to the top of the locking rod 31. The circular block 32 is located on top of the upper limit block 17 and is used to limit the upper limit block 17. When cleaning and maintenance of the device is required, the pin 26 can be pulled out first. At this time, the pin 26 no longer brakes the fixing rod 28 and the rectangular plate 29, and the pushing plate can be pushed. Pulling out the push plate 30 causes the fixed rod 28 and rectangular plate 29 to be pulled out. The rectangular plate 29 causes the clamping rod 31 and the round block 32 to move laterally, thereby causing the clamping rod 31 to move out of the inside of the first strip hole 25. The top of the round block 32 no longer abuts against the top of the upper limit block 17, and the feeding bin 4 can be flipped from one side. The feeding bin 4 causes the first connecting plate 9 to rotate around the rotating shaft 10, which can rotate the feeding bin 4 to one side, thereby cleaning the material stuck inside the upper crushing box 5.

[0034] This application can be used in the field of crushers, or in other fields applicable to this application.

The pin 26 is used to brake the fixing rod 28 and the rectangular plate 29. Two symmetrically arranged hooks 15 are fixedly connected to one side of the upper crushing box 5. Two symmetrically arranged buckles 16 are fixedly connected to one side of the lower crushing box 6. The hooks 15 and buckles 16 are used together to connect the upper crushing box 5 and the lower crushing box 6. A handle 14 is fixedly connected to one side of the upper crushing box 5. The top of the feeding bin 4 is fixedly connected to the feeding hopper 7. An observation window 8 is fixedly connected to one side of the top of the feeding bin 4.
