Description

Technical Field

[0001] The utility model relates to the technical field of pulverizer equipment, in particular to a pulverizer hammer head. Background Art

[0002] The hammer head is one of the core components of the hammer mill. It is arranged on the hammer shaft of the mill rotor. When the mill is running at high speed, the hammer head directly hits the material and finally breaks it into suitable material size. The existing hammer head is square. When the mill is working, the working surface of the hammer head is a plane, that is, the plane collides with the material, and the material and the hammer surface produce impact pits. The deformation caused by the impact pits causes the hammer surface to undergo work hardening and form a work hardening layer. At present, high manganese steel is commonly used as the main wear-resistant material to make hammer heads, which are easy-to-wear parts. However, since the hammer head is subjected to less impact in actual work, it cannot exert the wear-resistant characteristics of high manganese steel-type easy-to-wear parts. After its surface is hardened, it exhibits wear-resistant characteristics. This also causes the hammer head to be easily damaged and needs to be replaced frequently, affecting work efficiency.

[0003] In the prior art patent CN205020147U discloses a hammer head for a crusher, including a hammer head, a mounting portion, a bolt and a working plate. The hammer head is fixedly connected to the mounting portion. The hammer head includes a hammer head and a hammer handle. One end of the hammer handle is connected to the hammer head, and the other end of the hammer handle is connected to the mounting portion. The working plate is a metal plate with a shape and size similar to the side of the hammer head. The hammer head and the working plate are provided with through holes for matching bolts. When working, the working plate on the hammer head hits the stone. The working plate will protect the hammer head and prevent the hammer head from being worn. When the working plate is severely worn after working for a period of time, the nut can be removed and the entire working plate can be replaced. Maintenance and replacement are very convenient. By replacing the working plate, the service life of the hammer head is extended. Since the working plate is fixedly connected to the hammer head by bolts, replacing the working plate is also very convenient and quick.

[0004] However, in the above-mentioned prior art patents, the fixing and installation of the working plate on the hammer head requires the use of a large number of bolts and nuts, which takes a lot of time and manpower and is troublesome to operate. Utility Model Content

The above-mentioned solution solves the problem that the fixing and mounting of the existing working plate on the hammer head 101 requires the use of more bolts and nuts, which takes more time and manpower and is troublesome to operate.

[0023] According to this specific embodiment, the working plate 102 is arranged on the hammer head 101, one end of the hammer handle 103 is fixedly connected to the hammer head 101, and the mounting portion 104 is fixedly connected to the other end of the hammer handle 103. When working, the working plate 102 on the hammer head 101 hits the stone, and the working plate 102 will protect the hammer head 101 and prevent the hammer head 101 from being worn.

[0024] The hammer head 101 has a movable groove 114 and a cavity 115, the two limiting columns 105 are fixedly connected to the working plate 102 and are located on the outer side wall of the working plate 102, and the two limiting columns 105 are also movably connected to the hammer head 101 and inserted into the cavity 115, the two fixing columns 106 are arranged on the working plate 102 and are plugged into the hammer head 101, the two limiting columns 105 have fixing holes 116, the two movable plates 107 are movably connected to the hammer head 101 and are located in the cavity 115, and the two abutting blocks 109 are fixedly connected to the corresponding movable plates 107, respectively. The two ends of each of the holding springs 108 are respectively fixedly connected to the hammer head 101 and the corresponding movable plate 107.
