[0001] The utility model relates to the field of hammer mills, in particular to a reversible hammer head removal device for a hammer mill. Background Art

[0002] During the operation of the existing reversible impact hammer mill, the hammer head needs to be replaced regularly due to wear. When dismantling, first remove the side wall shaft cover, adjust the dismantled shaft and the shaft cover hole to be concentric, then one person holds the steel bar to align with the dismantled shaft, and another person uses a sledgehammer to hit the steel bar to exit the shaft to replace the hammer head. Using a person to swing a sledgehammer to hit the steel bar to exit the shaft is time-consuming and laborious, and the dismantling progress is slow. In addition, two people are required to assist in the dismantling. When the person is tired, the hammer is easy to hit the side or slip out of the hand, causing injury to the person holding the steel bar. In addition, the replacement time is long, resulting in long downtime, reduced production efficiency, and economic losses.
