Title:
JAW CRUSHER
Document Type and Number:
WIPO Patent Application WO/2022/120888
Kind Code:
A1
Abstract:
Provided is a jaw crusher, which solves the problem of an existing crusher being prone to device damage due to a flywheel still driving a rotating shaft to rotate when the crusher is overloaded. During use of the present invention, when a movable jaw plate is overloaded, a protection mechanism is driven by a control module to disconnect a rotating shaft from a flywheel, so that the flywheel is idling on the rotating shaft, and the unpowered rotating shaft and the movable jaw plate rapidly stop moving, thereby effectively preventing damage to a device caused by the flywheel, which has a larger mass, driving the rotating shaft and the movable jaw plate to continue to move, and thus effectively protecting the device. A control box controls a screw rod to rotate; and a drive block is driven by the screw rod to move in a gap between two fixed plates, and by means of a drive inclined plane of the drive block matching an adjusting seat, the adjusting seat is driven to move toward the movable jaw plate, so that a gap between the movable jaw plate and a fixed jaw plate is compensated for. Therefore, the gap between the movable jaw plate and the fixed jaw plate can be adjusted without stopping the device, which is convenient for use.
