The invention relates to the technical field of engineering equipment, in particular to an excavator bucket protection device which comprises an excavator arm, a hydraulic cylinder and a safety box. Abucket is arranged at the lower end of the excavator arm through a rotating shaft, a supporting rod is arranged on one side of the excavator arm through a first pin shaft, and the hydraulic cylinderis movably arranged on one side of the excavator arm. According to the device, a safety rod is used for applying pressure to a push plate, and different electromagnetic attraction blocks are matched.When the weight of an object in the bucket is large, the push plate pushes a sliding plate away from the first electromagnetic attraction block to the second electromagnetic attraction block with higher attraction force; and meanwhile, the bucket inclines, a part of the object in the bucket is properly and automatically poured out, and therefore the safe service life of the bucket is protected, and operation is easy. And through the butt joint relation between a reset rod and a movable block, the equipment can rapidly recover to the initial use state, and normal use of the equipment is not affected; and meanwhile, an L-shaped reset plate can conduct safety protection on the hydraulic cylinder and a piston column, and collision damage is reduced.
本发明公开涉及工程设备技术领域，具体为一种挖掘机铲斗保护装置，包括挖臂、液压缸和安全盒，所述挖臂的下端通过转轴设有铲斗，挖臂的一侧通过第一销轴设有支撑杆，液压缸活动设于挖臂的一侧，该装置通过安全杆对推板施加压力，配合不同的电磁吸块，当铲斗内的物体重量较大，推板会将滑板推离第一个电磁吸块送至第二个更高吸附力的电磁吸块，同时铲斗产生倾斜，将铲斗内的物体适当的自动倒出一部分，从而保护铲斗的安全使用寿命，操作简单，通过复位杆与活动块之间的对接关系，使设备快速进行恢复最初使用状态，不影响设备的正常使用，同时L形复位板可对液压缸以及活塞柱进行安全防护，减少碰撞损坏。
