Abstract
Description
Technical Field

[0002] A hammer crusher is a crushing equipment that uses impact to crush materials. It includes single-rotor and double-rotor structural forms. During production, the rotating rotor assembly drives the hammer arms and the hammer heads at the ends of the hammer arms to rotate. Under the drive of the rotor assembly, the hammer heads periodically hammer the material to crush it.
[0003] A search revealed Chinese patent application number 201910476233.1, which discloses a hammer crusher rotor mechanism and a hammer crusher. The rotor mechanism includes: a rotor shaft, a middle plate, end plates, spacers, a tensioning device, a positioning ring, an adjusting rod, a pin, hammer arms, and hammer heads. Bearing assemblies are respectively provided at both ends of the rotor shaft. The middle plate includes multiple plates, which are mounted on the rotor shaft, and spacers are mounted on the rotor shaft between two adjacent middle plates. The end plates include two plates, which are mounted on the rotor shaft and located on both sides of the multiple middle plates, and spacers are mounted on the rotor shaft between the end plates and the middle plates.
[0004] The above-mentioned patent has the following shortcomings: In actual use, the rotor structure mainly crushes materials through hammers. The hammers are limited and fixed by adjusting the tie rod. However, the hammers generate a very large impact force during operation, and the reaction force they bear is also very large. Under the action of the reaction force, it is easy to cause adverse effects on the adjusting tie rod, such as bending of the adjusting tie rod, which is not conducive to the later maintenance of the rotor structure.
