Abstract
Description
Technical Field
[0001] This utility model relates to the field of crusher technology, and in particular to an anti-clogging structure and a slow-speed crusher. Background Technology
[0002] In existing crusher technology, material feeding into the crusher can easily cause blockages, affecting the normal operation of the crusher and reducing production efficiency. At the same time, after long-term use, the crushing components inside the crusher (such as fixed protrusions, crushing blades, etc.) are prone to accumulating material residue, making cleaning and maintenance difficult. This not only affects the crushing effect but may also shorten the service life of the crusher.
[0003] Therefore, this application proposes an anti-clogging structure and a slow crushing method to solve the aforementioned problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing crusher technology, such as the tendency for material to clog when fed into the crusher, affecting its normal operation and reducing production efficiency. Furthermore, the internal crushing components (such as fixed protrusions and crushing blades) tend to accumulate material residue after prolonged use, making cleaning and maintenance difficult. This not only affects the crushing effect but may also shorten the crusher's lifespan. Therefore, this invention proposes an anti-clogging structure and a slow-speed crusher.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An anti-clogging structure includes a feeding box, a feeding hopper fixedly connected to one side of the top of the feeding box, an open bottom of the feeding box, a sliding block slidably passing through one side of the top of the feeding box, a pressing protrusion fixedly connected to the top of the sliding block, four first springs symmetrically connected in pairs between the bottom of the pressing protrusion and the top of the feeding box, and the bottom of the sliding block extending into the interior of the feeding box.
[0007] In one possible design, a sliding box is fixedly connected to the bottom of the sliding block. Both sides of the sliding box are slidably connected to the inner walls of the feed box via sliders and grooves. A transverse groove is provided inside the sliding box. Multiple strip grooves are provided on one side of the sliding box. One side of the transverse groove is connected to the multiple strip grooves. A common connecting plate is slidably connected between the inner walls of the two sides of the transverse groove. Two symmetrically arranged second springs are fixedly connected between one side of the connecting plate and one side of the inner wall of the transverse groove. Multiple strip rods are fixedly connected to one side of the connecting plate. One end of each strip rod slides through the strip groove and abuts against one side of the inner wall of the feed box.
[0008] A slow-speed pulverizer includes an anti-clogging structure as described above, and also includes a frame:
[0009] A first crushing box is fixedly connected to the top side of the frame, and a second crushing box is fixedly connected to the bottom of the first crushing box. The top side of the first crushing box is rotatably connected to the feed box through a connector. The bottom of the feed box is connected to the top of the first crushing box and is used to feed materials. The interior of the second crushing box is equipped with a crushing component for crushing materials.
[0010] In one possible design, the crushing assembly includes two symmetrically arranged semi-circular plates fixed inside the second crushing chamber. Fixed inclined plates are fixedly connected to the inner walls of both sides of the first crushing chamber. Multiple extrusion plates are fixedly connected to the sides of the fixed inclined plates. The first and second crushing chambers are rotatably connected to the same rotating roller on one side. Multiple fixed protrusions are fixedly connected to the outer wall of the rotating roller. The fixed protrusions cooperate with the extrusion plates. A servo motor is fixedly connected to one side of the top of the frame. The output shaft of the servo motor is fixedly connected to one end of the rotating roller.
[0011] In one possible design, two symmetrically arranged crushing blades are fixedly sleeved on the outer wall of the rotating roller, the semi-arc plate is located between multiple extrusion plates, the crushing blades are located inside the semi-arc plate and are used to crush the material, and the first crushing box and the second crushing box are fixedly connected by buckles and hooks.
[0012] In one possible design, the connector includes a second ear plate fixedly connected to one side of the feed box, a first ear plate fixedly connected to one side of the first crushing box, a fixed shaft fixedly connected between the inner walls of the two sides of the first ear plate, the second ear plate rotatably sleeved on the outer wall of the fixed shaft, a first limiting block fixedly connected to one side of the first crushing box, and a second limiting block fixedly connected to one side of the feed box. The second limiting block cooperates with the first limiting block and is used to fixally connect the feed box and the first crushing box.
[0013] In one possible design, a discharge hopper is fixedly connected inside the frame, the top of the discharge hopper is fixedly connected to the bottom of the second crushing box and is used to collect materials, a discharge pipe is fixedly connected to one side of the discharge hopper, and a blower is fixedly connected inside the frame. The air outlet of the blower is connected to one side of the discharge hopper through a pipe and is used to blow out materials.
[0014] In this application, during use, the material to be crushed is fed into the device through the feeding hopper and gradually enters the first crushing box along the inclined surface of the feeding box. The servo motor is started, and the output shaft of the servo motor drives the rotating roller to rotate. The rotating roller drives the external fixed protrusion and crushing blade to rotate. The fixed protrusion abuts against the extrusion plate to crush the material. The crushing blade can cut the material. The crushing blade is always located inside the semi-arc plate and repeatedly crushes the material. After being crushed again by the fixed protrusion and extrusion plate, the crushed material is discharged from the space between the two semi-arc plates.
[0015] The crushed material enters the discharge hopper. The blower is started, and the blower blows the material inside the discharge hopper out through the discharge pipe to realize the discharge process. After a period of use, the feed box can be rotated as a whole. The feed box rotates around the fixed shaft, which can separate the first crushing box from the feed box, making it easier to clean or maintain the fixed protrusions and crushing blades inside the first crushing box.
[0016] When material is fed in, it pushes the bar rod downwards. Since one end of the bar rod abuts against the inclined surface of the feed box, the bar rod can drive the bar groove to retract laterally into the inside of the bar groove and squeeze the connecting plate. One end of the bar rod is always in close contact with the inner wall of the feed box. At the same time, the sliding box drives the sliding block to move downwards, and the sliding block drives the pressing protrusion to move downwards and squeeze the first spring. When the material slides down, the sliding box and the bar rod will reset again, which can disturb the material and prevent the device from clogging. The same effect can be achieved by pressing the pressing protrusion from the outside. Manual operation reduces the possibility of clogging and is easy to use.
[0017] Beneficial effects: Anti-clogging function: By setting up an anti-clogging structure, when material is put into the feed box, the material pushes the strip rod downward, the strip rod drives the strip groove to retract laterally and squeeze the connecting plate. At the same time, the sliding box drives the sliding block downward, the sliding block drives the pressing protrusion to move downward and squeeze the first spring. After the material slides down, the sliding box and strip rod return to their original positions, which can disturb the material and prevent the device from clogging. In addition, the same anti-clogging effect can be achieved by pressing the pressing protrusion externally, effectively reducing the possibility of clogging and improving the stability of equipment operation.
[0018] Easy to clean and maintain: The feed box and the first crushing box are rotatably connected by a fixed shaft. After a period of use, the feed box can be rotated as a whole to separate the first crushing box from the feed box, making it easy to clean or maintain the fixed protrusions and crushing blades inside the first crushing box, ensuring the crushing effect and extending the service life of the equipment.
[0019] High-efficiency crushing: The servo motor drives the rotating roller to rotate. The fixed protrusion on the rotating roller cooperates with the extrusion plate to crush the material. The crushing blade cuts the material and is always located inside the semi-circular plate to repeatedly crush the material. The crushed material is crushed again by the fixed protrusion and extrusion plate and then discharged, which improves the crushing effect and efficiency of the material.
[0020] High-efficiency discharge: The crushed material enters the discharge hopper, the blower is started, and the blower blows the material inside the discharge hopper out through the discharge pipe, realizing a high-efficiency and smooth discharge process to meet the needs of rapid production.
[0021] Stable structure: The feed box and the first crushing box are rotatably connected by the first ear plate, the second ear plate and the fixed shaft, and are fixed by the first limit block and the second limit block, which ensures the stability of the equipment structure and ensures the safety and reliability of the equipment during operation.

[0031] Example 1
[0032] Reference Figure 1-7 An anti-clogging structure includes a feed box 5, with a feed hopper 3 fixedly connected to one side of the top of the feed box 5. The bottom of the feed box 5 is open.
