FIELD OF THE INVENTION The present invention relates to a crusher, and more particularly to an industrial lead-acid battery crusher, which belongs to the field of machinery. BACKGROUND OF THE INVENTION The recycling of the lead-acid battery is of great significance. It can not only recycle valuable lead resources, but also eliminate heavy metal ions contained in the battery. The modern maintenance-free battery of the environment generally adopts ABS plastic casing and more. For the sturdy structure, its strength and toughness are higher than the original open-cell battery. The hammer of the ordinary hammer crusher is not only easy to be damaged during the crushing process, but also difficult to break the galvanic battery to the required particle size. Increasing operating costs also affects work efficiency and work efficiency. SUMMARY OF THE INVENTION The present invention is to solve the problem that the prior art equipment is extremely expensive and complicated in process, and provides an industrial lead-acid battery crusher with a single process, low cost, good crushing effect and long service life.

The breaker is provided with a plurality of hammer plates, and a plurality of hammer bodies are staggered on the hammer plate. The hammers continuously strike the Xiamen battery during the rotation process, so that the battery is broken and repeatedly tapped. The crushed particle size is finer and the crushing effect is better. Preferably, in the present invention, the hammer shaft has at least four, and the hammer shaft adjacent to the hammer shaft to which the hammer body is attached is not mounted with a hammer body to limit the rotation of the hammer body. The hammer body is not mounted on the hammer shaft adjacent to the hammer shaft on which the hammer body is mounted. When the hammer body is struck back, the hammer shaft is not mounted, so that the hammer body and the hammer plate are relatively fixed. At this time, the hammer tip on the inner side of the hammer body and the hammer tip on the outer side are exposed on the hammer plate, and the battery can be struck at the same time. Preferably, in the present invention, a hammer body portion to which a hammer body is attached is provided between adjacent hammer disks, and a plurality of hammer bodies are uniformly disposed in the hammer body portion in the circumferential direction, and the hammer bodies provided in the adjacent hammer body portions are alternately interlaced. Preferably, in the present invention, the hammer plate and the rotating shaft are connected by a spline, and a positioning retaining spring is disposed between the adjacent hammer plates. As a preferred embodiment of the present invention, the hammer shaft is further provided with a positioning sleeve, and the positioning sleeve is fixed on the hammer shaft by a positioning pin. As a preferred aspect of the present invention, the hammer disk has a rotational speed of 1000 to 3000 rpm. The proper rotation speed can ensure better crushing effect. If it is too slow, the turning torque is insufficient, and the hammer body is easily blocked by the Xiamen battery and cannot be broken normally. In summary, the present invention has the following advantages:

1. The structure of the invention has the advantages of low cost, long service life and low maintenance cost;

2. The process of the invention is small, the process cylinder is simple, and the crushing effect is good.
