Description

Technical Field

[0001] The utility model relates to the technical field of hammer crushers, in particular to a hammer crusher with staggered mounted hammer heads. Background Art

[0002] Hammer crushers are widely used in the industrial field and are mainly used for the primary crushing of hard materials. Hammer crushers mainly rely on impact energy to complete the crushing operation. When the hammer crusher is working, the motor drives the rotor to rotate at high speed, and the material enters the crusher cavity evenly. The high-speed rotating hammer head impacts, shears and tears the material to be crushed. At the same time, the gravity of the material itself causes the material to rush from the high-speed rotating hammer head to the baffle and screen bars in the frame. There is a screen plate at the bottom of the rotor. The particle size smaller than the screen hole size in the crushed material is discharged through the screen plate, and the material larger than the screen hole size is retained on the screen plate and continues to be hit and ground by the hammer until it is crushed to the required discharge particle size and finally discharged from the machine through the screen plate. It has the advantages of large feed particle size, high yield and good particle shape.

[0003] The existing Chinese utility model patent with reference publication number CN107469934A discloses a hammer crusher comprising a material inlet, a baffle, a mouth guard, a housing, a lifting ring, a counterattack plate, a hammer, a side guard, a rotor disc, a rotor shaft, a front guard, a spacer ring, a transmission shaft, screen bars, a support screen plate, and a bracket. The material inlet is located at the upper right corner of the housing, the baffle is connected to the interior of the material inlet, the mouth guard is connected to the inner wall of the material inlet, the lifting ring is connected to the upper part of the housing, the counterattack plate is connected to the inner wall of the housing, the transmission shaft is connected to the center of the interior of the housing, a spacer ring is provided on the periphery of the transmission shaft, the rotor disc is connected to the spacer ring, the side guard is connected to the rotor disc, four hammers are evenly connected to the rotor disc and the side guard, the four hammers are respectively connected to the rotor shaft, the front guard is connected to the right side of the interior of the housing, the screen bars are connected to the lower part of the interior of the housing, the support screen plate is connected to the lower part of the exterior of the housing, and the bracket is connected to both sides of the exterior of the housing. The present invention has a simple structure, is easy to use, and is technically sound.

[0004] Based on the search of the above patents and combined with the equipment in the prior art, it was found that hammer crushers are widely used in the industrial field, mainly for the primary crushing of hard materials. Since the hammer head and liner are wear parts, they need to be replaced after long-term use. Most of the hammer crushers currently used on the market have problems such as inconvenient maintenance and replacement of parts, and the crushers are all running at full load, and the downtime for maintenance is insufficient. The original crusher is a single pulley structure with large operating resistance. The actual use efficiency of the motor reaches 80%. At the same time, the bearing loss is large, which can easily cause unilateral bearing heating, oil leakage, etc. The operating stability of the rotor cannot be guaranteed. The existence of these problems has affected the use of the device. Utility Model Content

Most of the hammer crushers currently used on the market have problems such as inconvenient maintenance and replacement of parts, and the crushers are all running at full load, and the downtime for maintenance is insufficient. The original crusher is a single pulley structure with large operating resistance. The actual use efficiency of the motor reaches 80%, and the bearing loss is large, which can easily cause unilateral bearing heating and oil leakage, and the rotor's operating stability cannot be guaranteed.
