Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1-4, the utility model relates to a wear-resistant hammer head, detachable connects on the pivot 2 between adjacent rotor 1, and the hammer head includes: a hammer head part 7, a mounting part detachably connected to the rotating shaft 2, and a connecting part 6 connected between the mounting part and the hammer head part 7; two perpendicular angle departments in the hammer head portion 7 outside all are detachable to be connected with wear-resisting lug 8.

The hammer head portion 7 of the present embodiment is made of high-chromium cast iron.

The hammer head of the embodiment is detachably connected to the rotating shaft 2 between the adjacent rotors 1; the number of the hammers can be set according to actual requirements.

The hammer head 7 of the present embodiment is outside the rotor 1.

The hammer head portion 7 of the present embodiment may have a rectangular shape, a fan shape, or other different structures conventionally used in the art.

The wear-resistant protrusions 8 of this embodiment are made of high-chromium cast iron.

Specifically, stone entering the crusher collides with the vertical angle of the rotating hammer head part 7, and the abrasion of the vertical angle of the hammer head part 7 is avoided by arranging the abrasion-resistant convex block 8, so that the service life of the crusher is prolonged; when the wear-resistant convex block 8 is damaged, only the wear-resistant convex block 8 needs to be replaced, and the replacement cost is low.

Further, the mounting portion includes: the first mounting frame 4 and the second mounting frame 5 matched with the first mounting frame 4 are detachably connected; one end of the connecting part 6 is connected with the outside of the first mounting frame 4 or the second mounting frame 5.

In this embodiment, the first mounting bracket 4 includes: the first arc-shaped part 41 is matched with the outer part of the rotating shaft 2, and the two ends of the first arc-shaped part 41 are respectively extended with a first connecting part 42.

In this embodiment, the second mount 5 includes: a second arc-shaped part 51 which is matched with the outer part of the rotating shaft 2 and is matched with the first arc-shaped part 41, wherein two ends of the second arc-shaped part 51 are respectively extended with a second connecting piece 52; the second connecting member 52 is connected to the first connecting member 42 by a screw and a nut.

Specifically, the first arc-shaped member 41 and the second arc-shaped member 51 are wrapped outside the rotating shaft 2, and a screw rod is passed between the second connecting member 52 and the first connecting member 42, and is fixed by a nut.

Further, mounting platform 71 has all been seted up to two perpendicular angle departments in the tup portion 7 outside, has inwards seted up T type groove 72 in mounting platform 71, and wear-resisting lug 8 bottom is connected in T type groove 72 through T type spare 81.
