[0025] Example

[0026] like Figure 1-5 As shown, a dust removal crusher for coal blending with anti-clogging characteristics includes a conveying cylinder 1. A crushing box 2 is fixedly connected to the outer surface of the conveying cylinder 1. A rotating rod 3 is rotatably connected to the middle of the inner side of the conveying cylinder 1. The rotating rod 3 passes through the conveying cylinder 1. An auger 4 is fixedly connected to the outer surface of the rotating rod 3. A turntable 5 is fixedly connected to one end of the rotating rod 3. A protrusion 6 is fixedly connected to the edge of the upper surface of the turntable 5. A connecting rod 7 is slidably connected to the outer surface of the protrusion 6. A guide groove 8 is opened in the middle of the upper surface of the connecting rod 7. One end of the connecting rod 7 is rotatably connected to the conveying cylinder 1. A corrugated pipe 9 is fixedly connected to the other end of the connecting rod 7. The corrugated pipe 9 is fixedly connected to the conveying cylinder 1.

[0027] In practical use, the conveying cylinder 1 is connected to the crushing box 2 via the auger 4, turntable 5, connecting rod 7, and bellows 9, forming a continuous operating channel. The crushing box 2, as the main frame of the entire crusher, bears all components. Its internal space is rationally designed to provide sufficient space for the crushing process. Driven by the rotating rod 3, the auger 4 generates a spiral propulsion force, forcibly feeding the coal into the crushing box 2 through the bellows 9, achieving continuous coal conveying. This allows the coal to enter subsequent processing stages without interruption, thereby improving production efficiency and achieving continuous production. The blades of the auger 4 can be variable... The screw pitch design, with a denser front and sparser rear structure, features a high compression ratio at the front to prevent coal backflow, while the large screw pitch at the rear improves conveying efficiency. The screw ensures even distribution of coal, preventing accumulation, and the rotation of the auger 4 initially loosens wet coal clumps, reducing the risk of adhesion during subsequent crushing. Simultaneously, the rotating rod 3 drives the turntable 5 to rotate, causing the protrusion 6 on its top to slide inside the guide groove 8. This, in turn, causes the connecting rod 7 to drive the bellows 9 to oscillate regularly, ensuring that the coal is more evenly distributed on the crushing mechanism during conveying, further preventing coal accumulation or blockage, and ensuring that the coal can smoothly enter the subsequent processing stages.

[0028] In this embodiment, a first crushing roller 10 is rotatably connected to one side of the inside of the crushing box 2, and a second crushing roller 11 is rotatably connected to the other side of the inside of the crushing box 2.

[0029] In practical use, the teeth of the first crushing roller 10 and the second crushing roller 11 are arranged in an alternating manner, so that the coal can be fully subjected to shearing and compressive forces when passing through, thereby achieving efficient crushing, reducing the mutual adhesion and accumulation between coal blocks, and enhancing the crushing effect.

[0030] In this embodiment, a first motor 12 is fixedly connected to one end of the first crushing roller 10, and the first motor 12 is fixedly connected to the crushing box 2. A second motor 13 is fixedly connected to the other end of the rotating rod 3, and the second motor 13 is fixedly connected to the conveying cylinder 1.

[0031] In practical use, the first motor 12 is used to drive the first crushing roller 10, and the second motor 13 is used to drive the rotating rod 3, so that the device can achieve mechanized drive and speed up the work efficiency.

[0032] In this embodiment, the other end of the first crushing roller 10 is fixedly connected to a drive gear 14, and one end of the second crushing roller 11 is fixedly connected to a driven gear 15. The drive gear 14 and the driven gear 15 are meshed together.

[0033] In practical use, the driving gear 14 and the driven gear 15 mesh with each other. The two are different in size, so as to realize the relative differential operation of the first crushing roller 10 and the second crushing roller 11, which makes them have a mutual scraping effect, which can clean the coal between the teeth in time and avoid coal accumulation in the teeth and blockage.

[0034] In this embodiment, baffles 16 are fixedly connected to both sides of the middle part of the inner side of the crushing box 2.

[0035] In practical use, two sets of baffles 16 are symmetrically arranged inside the crushing box 2 to form a V-shaped flow channel, which prolongs the residence time of coal inside the crushing box 2 and prevents uncrushed coal from flowing downward.

[0036] In this embodiment, a guide plate 17 is fixedly connected to the bottom of the inner side of the crushing box 2, and a receiving plate 18 is fixedly connected to the outer surface of the crushing box 2 near the guide plate 17.

[0037] In practical use, the guide plate 17 has an inclined structure, which allows the crushed coal inside the crushing box 2 to be better transported to the outside and reduces internal residue. The receiving plate 18 is used to receive the crushed coal inside the crushing box 2, so that it is convenient for staff to collect it in a centralized manner.

[0038] In this embodiment, a dust suction hood 19 is fixedly connected to the upper surface of the crushing box 2, and a dustproof cloth 20 is fixedly connected to the outer surface of the dust suction hood 19. The dustproof cloth 20 is fixedly connected to the corrugated pipe 9.

[0039] In practical use, the dust hood 19 covers the top opening of the crushing box 2 to prevent dust from drifting away and reduce pollution to the surrounding environment. The dustproof cloth 20 covers the surface opening of the dust hood 19 and is connected to the corrugated pipe 9. The dustproof cloth 20 is extensible and can adapt to the position changes of the corrugated pipe 9.

[0040] In this embodiment, a suction pipe 21 is fixedly connected to the outer surface of the dust collection hood 19, a vacuum cleaner 22 is fixedly connected to one end of the suction pipe 21, the vacuum cleaner 22 is fixedly connected to the crushing box 2, and a waste discharge pipe 23 is fixedly connected to the bottom of the outer surface of the vacuum cleaner 22.

[0041] In practical use, one end of the exhaust pipe 23 is connected to the vacuum cleaner 22, and the other end can be connected to an external dust removal device. The vacuum cleaner 22 absorbs the dust accumulated inside the dust hood 19 through the suction pipe 21, and then discharges it into the dust removal device through the exhaust pipe 23 for purification treatment to meet environmental emission standards.

[0042] Working principle: Coal is placed inside the conveying cylinder 1. The second motor 13 drives the rotating rod 3. Under the drive of the rotating rod 3, the auger 4 forms a spiral propulsion force, forcibly feeding the coal into the crushing box 2 through the bellows 9. At the same time, the rotating rod 3 drives the turntable 5 to rotate, causing the protrusion 6 to slide inside the guide groove 8. The connecting rod 7 drives the bellows 9 to perform regular reciprocating oscillation, so that the coal is more evenly distributed on the crushing mechanism during the conveying process, avoiding coal accumulation or blockage. The first motor 12 drives the first crushing roller 10. The driving gear 14 and the driven gear 15 mesh with each other to realize the relative differential speed movement of the first crushing roller 10 and the second crushing roller 11. The rotation allows the coal to be fully subjected to shear and compressive forces as it passes through, thus achieving efficient crushing. Two sets of baffles 16 extend the residence time of the coal inside the crushing box 2, while preventing uncrushed coal from flowing downwards. The crushed coal is conveyed to the outside under the action of the guide plate 17. The receiving plate 18 is used to receive the crushed coal inside the crushing box 2. The dust hood 19 and the dustproof cloth 20 cover the top opening of the crushing box 2. The vacuum cleaner 22 absorbs the dust accumulated inside the dust hood 19 through the dust suction pipe 21, and then discharges it into the dust removal equipment through the waste discharge pipe 23 for purification treatment to meet environmental emission standards.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
