Abstract

The invention discloses a cutter overload protection system comprising a cutter shaft rotationally arranged on a machine frame, a movable cutter arranged on the circumferential face of the cutter shaft, a cutter holder connected to the machine frame in a turnover mode, a fixed cutter arranged on the cutter holder and meshed with the movable cutter, and a first driving component arranged on the machine frame and connected with the cutter holder. When the pressure between the movable cutter and a fixed cutter is overloaded, the cutter holder is driven to overturn so that the movable cutter and the fixed cutter can be disengaged and a gap can be reserved for foreign matters to pass through. Therefore, according to the cutter overload protection system provided by the invention, when the pressure of the movable cutter and the fixed cutter is overloaded, the fixed cutter is separated from the movable cutter after being overturned along with the cutter holder through the driving effect of the first driving part on the cutter holder, the larger gap is reserved to make the foreign matters fall off in time, and the cutter overload protection of a shear crusher can be achieved. The cutters are prevented from being damaged during overload, equipment overload shutdown is avoided, and the production efficiency is improved. The invention further discloses the shear crusher.

Description

technical field

[0001] The invention relates to the technical field of crushers, in particular to a tool overload protection system. The invention also relates to a shear crusher. Background technique

[0002] Shear crushers are widely used in the crushing and volume reduction treatment of various wastes in the environmental protection industry.

[0003] The composition of the material to be crushed is complex, and the core part of the shear crusher - the cutter head (including the moving knife and the fixed knife) has a harsh working environment, and it is easy to chip or be damaged after long-term use. The traditional shearing crusher does not have a protection system for the cutter head. It can only be shut down for cleaning and maintenance after abnormal noise of the equipment, cutter shaft jamming or motor overload protection is found, or the cutter is found during daily shutdown maintenance. damage.

[0004] The various existing shearing crushers usually have the fo...
