Full-hydraulic crushing scarifier of excavator

Abstract

The invention discloses a full-hydraulic crushing scarifier of an excavator. The scarifier comprises a scarifier shell and a tooth bucket which are movably connected, a hydraulic impactor is arranged in the scarifier shell, a first telescopic oil cylinder is connected to the top of the scarifier shell, a rotating shaft is arranged at the bottom of the first telescopic oil cylinder, and a connecting rod is arranged in the middle of the rotating shaft in a sleeving mode. The two sides of the rotating shaft are sleeved with push rods, the sides, away from the rotating shaft, of the push rods are connected with second telescopic oil cylinders through second movable nodes, and a third telescopic oil cylinder is movably connected with a bucket. The scarifier has the beneficial effects that the first telescopic oil cylinder and the hydraulic impacter are arranged, and the first telescopic oil cylinder and the hydraulic impacter work independently, so that the scarifier has the functions of crushing rocks and loosening soil at the same time. In addition, the second telescopic oil cylinder is arranged to drive the push rod to move, so that independent rock crushing and soil loosening operation is guaranteed, and the service life of the first telescopic oil cylinder and the service life of the hydraulic impactor are prolonged.

Description

technical field [0001] The invention relates to the technical field of excavator equipment, in particular to an excavator full hydraulic crushing ripper. Background technique [0002] The excavator ripper is also called bucket hook, which is a replaceable working device with the function of turning the soil. In the actual working process, the ripper has a relatively single function. When performing soil loosening operations in earthworks, an excavator with a breaker is generally required. Used together, when the ripper cannot loosen the rock, an excavator with a breaker is needed at this time. After the large rock is broken and decomposed by the breaker, the bulldozer ripper is used to peel it off. This requires two pieces of equipment to work separately , the equipment cost is relatively high, and the time-wasting operation leads to relatively low work efficiency. [0003] For example, the patent No. CN105735401B discloses a broken ripper. Under the compensation of the imp...

Problems solved by technology

[0003] For example, the patent No. CN105735401B discloses a broken ripper. Under the compensation of the impact force of the impact component, it gives the ripper teeth an auxiliary impact ability to impact the earth and stone again, greatly improving the progress of loosening the rock, reducing energy consumption and Labor cost of personnel, but it cannot stir the soil and rocks after crushing. Patent No. CN203022046U discloses a multifunctional ripper for bulldozers. Hammer realizes the crushing operation. The progress of this working method is relatively limited, and the mobility is poor. It can be seen that the existing rippers have relatively single functions and cannot perform multi-functional operations. Frequent replacement of rippers in the actual use process not only Will increase workload and reduce work efficiency
