Problems solved by technology
Whether the bucket oil cylinder is normal is very important to the normal operation of the whole machine, and the excavator is usually exposed to the open environment, and the bucket oil cylinder is generally set above the stick, so the bucket oil cylinder may be damaged due to external force or The material is damaged due to the impact of the material, and many existing earthwork excavators do not have protective devices for the bucket cylinder, which is also a difficult test for the quality of the bucket cylinder

The invention provides an excavator bucket oil cylinder protection mechanism. The excavator bucket oil cylinder protection mechanism comprises a bucket rod, a bucket and a bucket oil cylinder and further comprises front supporting frames, rear supporting frames, rockers, connecting rods and protection devices, wherein the front supporting frames are of triangular structures, lug plates are arranged on the bucket, first ends of the front supporting frames are hinged to the lug plates through a first rotating shaft, second ends of the front supporting frames are hinged to one ends of the rockers through a second rotating shaft, the other ends of the rockers are hinged to the bucket rod, the two ends of the connecting rods are hinged to the first rotating shaft and the second rotating shaft respectively, the front end of the bucket oil cylinder is hinged to the second rotating shaft, the rear end of the bucket oil cylinder is hinged to the bucket rod, third ends of the front supporting frames are hinged to the front ends of the protection devices through a third rotating shaft, the rear supporting frames are fixed to the rear end of the bucket rod, the rear ends of the protection devices are hinged to the rear supporting frames through a fourth rotating shaft, the protection devices are located above the bucket oil cylinder and are arranged in a spaced mode with the bucket oil cylinder, and the protection devices are of telescopic structures.
Description
technical field [0001] The invention relates to the technical field of excavator structures, in particular to an excavator bucket oil cylinder protection mechanism. Background technique [0002] As a common component in excavators, oil cylinders play the role of actuators in working devices. They are divided into boom oil cylinders, bucket bar oil cylinders and bucket oil cylinders. Under the mutual cooperation of the three types of oil cylinders, the excavator has a strong digging force, of which the thrust provided by the bucket oil cylinder accounts for the vast majority of the digging force. [0003] An excavator generally includes a stick and a bucket hinged with the front end of the stick. Both ends of the bucket cylinder are hinged with the bucket and the stick, respectively, so as to drive the bucket to rotate relative to the stick to complete the excavation work. Whether the bucket oil cylinder is normal is very important to the normal operation of the whole machin...
