Description

Technical Field

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

[0002] The crusher uses the impact principle to break the stone into smaller pieces. The traditional crusher includes a base, a top cover, and a combined cylindrical crushing chamber with a constant diameter from top to bottom. A vertical shaft is arranged on the center line of the crushing chamber, and a crushing mechanism is installed on the vertical shaft. The motor and the belt transmission mechanism drive the vertical shaft and the crushing mechanism installed on the vertical shaft to rotate at high speed to achieve the crushing of the ore. Among them, the hammer crusher mainly relies on the impact energy of the hammer head to complete the material crushing operation. When the vertical shaft hammer crusher is working, the motor drives the main shaft to rotate, so that the hammer head installed on the main shaft rotates at high speed, and the material enters the crusher cavity evenly, thereby completing the crushing operation.

[0003] However, the new vertical shaft hammer crusher is easy to cause the material to get stuck in the feed port and inside because of the consistent hammering length of the internal hammer after filling, and it needs manual processing, which is very inconvenient. In addition, the internal protection of the crusher is poor, and the rotor disk is often damaged, resulting in poor crushing effect of the equipment. Utility Model Content
