[0002] Hammer crushers are widely used in industries such as coal, power, cement, chemical, and metallurgy for crushing medium-hard materials, such as coal, limestone, and slag, for medium and fine crushing operations.

[0003] Currently, when traditional hammer crushers crush materials with high moisture content, the screen holes are easily clogged, preventing the crushed material from being discharged through the screen plate. After long-term use, material tends to accumulate at the inlet and outlet of the crusher, causing blockages that require the machine to be stopped for cleaning.

[0004] Therefore, it is necessary to provide a new anti-clogging hammer crusher to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problems of easy clogging of the screen plate, difficulty in handling wet materials, inconvenient maintenance, and frequent shutdowns for unclogging, this utility model provides an anti-clogging hammer crusher.

[0010] Preferably, the moving mechanism includes: an electric guide rail fixedly mounted on the top of the base for driving the connecting plate to move; a connecting frame fixedly mounted on the output block of the electric guide rail, the connecting frame being fixedly connected to the connecting plate; and a reinforcing screw threadedly mounted on one side of the housing for fixing the connecting plate, the reinforcing screw being threadedly connected to the connecting plate.

[0011] Preferably, a guide rod is fixedly installed on one side of the housing, and a guide block is slidably installed on the guide rod. The guide block is fixedly connected to the connecting plate to assist in supporting the connecting plate.

[0012] Preferably, a connecting block is fixedly installed on one side of both the sieve plate and the housing, the two connecting blocks are arranged opposite to each other, and a connecting screw for limiting the sieve plate is threaded onto the two connecting blocks.

[0013] Compared with related technologies, the anti-clogging hammer crusher provided by this utility model has the following beneficial effects: This utility model provides an anti-clogging hammer crusher: 1. The rotating disc and hammer are driven by pulleys and belts to rotate at high speed, which powerfully impacts and crushes the material.

This structure is reliable and makes the replacement or adjustment of the hammer simple and quick, which greatly reduces the difficulty of maintenance and time cost. 2. The inclined feed hopper conforms to the law of material gravity flow, which facilitates feeding. The moving mechanism can drive the connecting plate to move out together with the impact plate, quickly opening the internal space. This makes the inspection, replacement and maintenance of internal components such as the impact plate and hammer body extremely convenient, and significantly improves the maintainability of the equipment. 3. The sliding cooperation between the guide rod and the guide block provides effective auxiliary support and precise guidance for the movement of the connecting plate, ensuring a smooth, stable, and safe maintenance operation. The cooperation between the connecting block and the connecting screw makes the disassembly and replacement of the screen plate, or the selection of whether to install the screen plate according to the material characteristics, very flexible.

The anti-clogging hammer crusher includes: a base 15 and a housing 1 mounted on the base 15; a rotating disk 2 rotatably mounted inside the housing 1; a hammer 3 detachably mounted on the rotating disk 2; a connecting plate 4 slidably mounted in an operating port on one side of the housing 1; an impact plate 5 detachably mounted on one side of the inner wall of the connecting plate 4; a screen plate 13 slidably mounted in a discharge port at the bottom of the housing 1 for screening materials; a servo motor 6 fixedly mounted on the base 15, with pulleys 7 fixedly fitted on both the output shaft of the servo motor 6 coupling and the rotating shaft of the rotating disk 2; a belt 8 fitted on a set of pulleys 7; and a moving mechanism mounted on the base 1 for driving the connecting plate 4 to move, thereby facilitating the inspection of the impact plate 5 and internal components of the housing 1. The mechanism drives the rotating disk 2 and hammer 3 to rotate at high speed via the pulleys 7 and belt 8, powerfully impacting and crushing the materials, and effectively screening the crushed materials through the screen plate 13 to ensure uniform output particle size and meet different production needs.

[0018] A feed hopper 9 is fixedly installed on the top of the housing 1. A baffle 10 is rotatably installed inside the feed hopper 9 to prevent material splashing. The baffle 10 effectively suppresses the rebound and splashing of material particles during feeding, reduces dust pollution, improves operational safety, and creates a cleaner and safer working environment.

[0019] A U-shaped plate 11 is fixedly installed on the rotating disk 2. The U-shaped plate 11 is connected to the hammer body 3, and a fastening bolt 12 for fixing the hammer body 3 is threaded on the U-shaped plate 11. The fastening bolt 12 is threadedly connected to the hammer body 3. Through the cooperation of the U-shaped plate 11 and the fastening bolt 12, the hammer body 3 is detachably mounted on the rotating disk 2. This structure is reliable and makes the replacement or surface adjustment of the hammer body 3 simple and quick, greatly reducing the maintenance difficulty and time cost.

[0020] The feed hopper 9 is inclined, and the discharge hopper 14 is fixedly installed at the bottom of the housing 1. The discharge hopper 14 is connected to the discharge port. The inclined feed hopper 9 conforms to the law of material gravity flow, which facilitates feeding.

[0021] The moving mechanism includes: an electric guide rail 16 fixedly installed on the top of the base 15 for driving the connecting plate 4 to move; a connecting frame 17 fixedly installed on the output block of the electric guide rail 16, the connecting frame 17 being fixedly connected to the connecting plate 4; and a reinforcing screw 18 threadedly installed on one side of the housing 1 for fixing the connecting plate 4, the reinforcing screw 18 being threadedly connected to the connecting plate 4. Through the setting of the moving mechanism, the connecting plate 4 can be driven to move out together with the counterattack plate 5, quickly opening the internal space, making the inspection, replacement and maintenance of internal components such as the counterattack plate 5 and the hammer 3 extremely convenient, and significantly improving the maintainability of the equipment.

[0022] A guide rod 19 is fixedly installed on one side of the housing 1, and a guide block 20 is slidably installed on the guide rod 19. The guide block 20 is fixedly connected to the connecting plate 4 to assist in supporting the connecting plate 4. Through the sliding cooperation between the guide rod 19 and the guide block 20, effective auxiliary support and precise guidance are provided for the movement of the connecting plate 4, ensuring the smoothness and safety of the maintenance operation process.

[0023] A connecting block 21 is fixedly installed on one side of both the screen plate 13 and the housing 1. The two connecting blocks 21 are arranged opposite each other, and a connecting screw 22 for limiting the screen plate 13 is threaded onto the two connecting blocks 21. Through the cooperation of the connecting blocks 21 and the connecting screw 22, the operation of disassembling and replacing the screen plate 13 or selecting whether to install the screen plate 13 according to the material characteristics is very flexible, which enhances the equipment's adaptability to different materials, especially high-moisture materials, and fundamentally solves the clogging problem.

[0024] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0025] The working principle of the anti-clogging hammer crusher provided by this utility model is as follows: This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here. When in use, the servo motor 6 drives the pulley 7 on the output shaft to rotate through the coupling. With the help of the belt 8, it drives another pulley 7 installed on the rotating shaft of the rotating disk 2 to rotate synchronously, so that the rotating disk 2 rotates at high speed in the housing 1, and the hammer 3 fixed on the rotating disk 2 rotates at high speed accordingly. Material is evenly fed into the crushing chamber from the feed hopper 9. The baffle 10 installed inside the feed hopper 9 can effectively prevent material from splashing during the feeding process. The high-speed rotating hammer 3 impacts, shears and tears the material to achieve initial crushing.

[0026] During the crushing process, under the influence of gravity and the impact of the hammer 3, the material is propelled towards the impact plate 5 installed inside the connecting plate 4, where it is further crushed by impact and rebound, thus improving crushing efficiency. The crushed material falls onto the screen plate 13 at the bottom of the shell 1 for screening. Particles smaller than the screen aperture size fall through the screen plate 13 into the discharge hopper 14 and are discharged from the machine; materials larger than the screen aperture size remain on the screen plate 13 and continue to be struck and ground by the hammer 3 until they reach the qualified particle size and are then discharged through the screen plate 13.

[0027] When crushing materials with high moisture content, the screen plate 13 can be omitted depending on the actual situation to avoid clogging. In this case, the crushed material is discharged directly through the discharge port and discharge hopper 14. When the impact plate 5 or hammer 3 needs to be inspected or replaced, first loosen and remove the reinforcing screw 18 to detach it from the connecting plate 4. Then, start the electric guide rail 16 to drive the connecting frame 17 and the connecting plate 4 fixed thereto to move outward along the operating opening of the housing 1. During this process, the guide block 20 fixed on the connecting plate 4 slides along the guide rod 19 to provide auxiliary support and guidance, ensuring that the connecting plate 4 moves out smoothly. As the connecting plate 4 moves, the impact plate 5 gradually exits from the housing 1, and the operating opening is fully open, making it convenient for operators to disassemble and replace the impact plate 5. The replacement of the hammer 3 is completed by unscrewing the fastening bolt 12 and removing the hammer 3 from the U-shaped plate 11. In addition, the installation and replacement of the screen plate 13 are achieved through the connecting block 21 and the connecting screw 22. After removing the connecting screw 22, the screen plate 13 can be slid off. Different specifications of screen plates can be selected according to the material characteristics, or the screen plate can be left uninstalled.

[0028] Compared with related technologies, the anti-clogging hammer crusher provided by this utility model has the following beneficial effects: This utility model provides an anti-clogging hammer crusher. A rotating disc 2 and hammer 3 are driven to rotate at high speed by a pulley 7 and a belt 8, providing powerful impact and crushing to the material. The crushed material is effectively screened by a screen plate 13, ensuring uniform output particle size to meet different production needs. A baffle 10 effectively suppresses the rebound and splashing of material particles during feeding, reducing dust pollution, improving operational safety, and creating a cleaner and safer working environment. The hammer 3 is detachably mounted on the rotating disc 2 using a U-shaped plate 11 and fastening bolts 12. This structure provides reliable connection and simplifies and speeds up the replacement or adjustment of the hammer 3, greatly reducing maintenance difficulty and time costs. The inclined feed hopper 9 conforms to the material's gravity. The flow pattern facilitates material feeding. The moving mechanism allows the connecting plate 4 to move along with the impact plate 5, quickly opening the internal space. This makes the inspection, replacement, and maintenance of internal components such as the impact plate 5 and hammer 3 exceptionally simple, significantly improving equipment maintainability. The sliding cooperation between the guide rod 19 and guide block 20 provides effective auxiliary support and precise guidance for the movement of the connecting plate 4, ensuring a smooth, stable, and safe maintenance process. The cooperation between the connecting block 21 and connecting screw 22 allows for highly flexible disassembly and replacement of the screen plate 13, or the selection of whether to install the screen plate 13 based on material characteristics. This enhances the equipment's adaptability to different materials, especially high-moisture materials, fundamentally solving the clogging problem.
