Description
Technical Field
[0001] This utility model belongs to the technical field of hammer crushers, specifically a self-adjusting intelligent hammer crusher. Background Technology
[0002] A hammer crusher is a key piece of equipment that uses high-speed rotating hammers to impact and crush materials. Its working principle is that the material is violently impacted by the hammers in the crushing chamber and thrown against the impact plate for secondary crushing. Finally, the discharge particle size is controlled by the screen plate at the bottom. With its simple structure, large crushing ratio and high production efficiency, this type of machine has been widely used in mining, cement, metallurgy and construction waste treatment and other fields. It is mainly used for medium and fine crushing of various brittle materials with medium hardness and below.
[0003] However, in the existing technology, traditional hammer crushers have obvious shortcomings in the design and maintenance of core components. On the one hand, the hammer shaft holes on the rotor disc are usually only set with four. When the working hammer shaft and hammer head are worn to the point of needing replacement, the entire huge rotor assembly must be shut down and completely disassembled. This process is not only cumbersome and laborious, but also significantly extends the equipment downtime, seriously affecting the efficiency of continuous production. On the other hand, the protection of the outer edge of the rotor disc in the traditional design is often achieved by welding a wear-resistant layer onto the substrate. The wear-resistant layer formed by this process is prone to peeling off under high-speed and high-load conditions. Its overall protection effect is poor and it is difficult to replace, which makes the rotor disc body susceptible to wear and premature damage, increasing maintenance costs and safety risks.

[0024] Please see Figures 1-4 This utility model provides a self-adjusting intelligent hammer crusher, including a base 1, a frame 2 fixedly mounted on the upper end of the base 1, an impact plate 3 fixedly mounted on the inner wall of the frame 2, a maintenance plate 4 movably mounted on one end of the frame 2, a crushing mechanism 5 movably mounted inside the frame 2, the crushing mechanism 5 including a rotor disc 501, several rotor discs 501 movably mounted inside the frame 2, a square shaft 503 passing through the rotor disc 501, a main shaft 502 fixedly mounted on one end of the square shaft 503, eight hammer shaft holes 504 opened on the rotor disc 501, a baffle plate 7 maintaining a vertical closed state under the configuration of a counterweight block 9 to effectively prevent material splashing, a rotating shaft 8 enabling the baffle plate 7 to rotate controllably when impacted by material, a feeding bin 6 receiving incoming material and guiding the material flow, the rotor disc 501 being connected to the main shaft 502 via the square shaft 503 to form a power transmission system, and the hammer shaft 505 passing through the hammer shaft holes 504 to fix the hammer head 507 to form a crushing unit.
[0025] Furthermore, such as Figure 2 and Figure 3 As shown, hammer shafts 505 are installed inside the four hammer shaft holes 504. A protective sleeve 506 is fixed to the outer ring of the rotor disk 501 by bolts. Hammer heads 507 are movably installed on the hammer shafts 505. A feeding bin 6 is fixedly installed at the upper end of the frame 2. A baffle plate 7 is movably installed on the inner wall of the feeding bin 6. A rotating shaft 8 is installed between the baffle plate 7 and the feeding bin 6. The hammer shaft 505 is the mounting shaft of the hammer head 507. The hammer head 507 is the core vulnerable part that directly impacts the material to achieve material crushing through high-speed impact. The protective sleeve 506 is installed on the outer edge of the rotor disk 501 to provide protection and rotates synchronously with the rotor. The impact plate 3 is a wear-resistant part fixed on the machine body and collides with the projectile material to achieve secondary crushing.
[0026] Furthermore, such as Figure 4As shown, a counterweight 9 is fixedly installed at the bottom of the baffle plate 7, a motor 10 is fixedly installed at the upper end of the base 1, a transmission belt 11 is movably installed between the motor 10 and the main shaft 502, a grate plate 13 is fixedly installed at the bottom of the frame 2, a feeding chute 12 is opened on the lower side of the grate plate 13, a side liner plate 14 is fixedly installed on the inner wall of the frame 2, the side liner plate 14 is a protective plate on the side of the crushing chamber and rubs against the material to achieve further grinding, the grate plate 13 is the final screening device to control the discharge of qualified material through its gaps, the feeding chute 12 is the final collection and guiding channel for qualified material, and the maintenance plate 4 provides a personnel passage for internal inspection and maintenance of the equipment.
[0027] Working principle: Material is fed into the feed hopper 6. The baffle plate 7, with the counterweight 9, remains vertically closed to effectively prevent material splashing. The rotating shaft 8 enables the baffle plate 7 to rotate controllably when impacted by material. The motor 10 drives the main shaft 502 to rotate via the transmission belt 11. The main shaft 502 drives the square shaft 503 to rotate synchronously. Several rotor discs 501 fixed on the square shaft 503 rotate at high speed. The hammers 507 mounted on the hammer shaft 505 expand radially under centrifugal force. The outer sheath 506 of the rotor disc 501 rotates synchronously with the rotor. After the material enters the crushing chamber, it is first impacted by the hammers. The violent impact of hammer 507 causes the crushed material to be thrown against the impact plate 3 for secondary crushing. Subsequently, the material is ground and crushed on the surface of the side liner plate 14. Material that does not meet the particle size requirements continues to be repeatedly impacted by hammer 507 in the crushing chamber. Qualified material falls through the gaps in the grate plate 13 and is finally discharged from the machine body through the feed chute 12. Throughout the process, the maintenance plate 4 provides a channel for equipment maintenance. The design of eight hammer shaft holes 504 ensures that the backup station can be used immediately when the four sets of hammer shafts 505 are worn. The base 1 provides stable support for the entire equipment. This structure realizes continuous and efficient operation of the crushing operation.

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.
