The invention discloses an excavator bucket oil cylinder. The bucket oil cylinder comprises a bucket cylinder barrel, a guiding sleeve and a piston rod, and the guiding sleeve is arranged at the end portion of the bucket cylinder barrel through an installing screw. The bucket cylinder barrel is further provided with an O-shaped ring for sealing between the bucket cylinder barrel and the guiding sleeve. A dustproof ring is arranged at the uppermost position where the guiding sleeve and the piston rod are connected, and an upper guiding sleeve and a lower guiding sleeve are arranged below the dustproof ring. The guiding sleeve is provided with an oil inlet channel, the oil inlet channel is in a 1 / 4 arc shape with the point A on the bucket cylinder barrel as the circle center, an upper sealing gasket cavity and a lower sealing gasket cavity are formed between the upper guiding sleeve and the lower guiding sleeve, an upper sealing gasket is arranged in the upper sealing gasket cavity, a lower sealing gasket is arranged in the lower sealing gasket cavity, and the interface of the upper sealing gasket and the lower sealing gasket is in an equilateral hexagon shape. The excavator bucket oil cylinder has the beneficial effects that the sealing gaskets are not prone to deformation during long-term usage, and the phenomenon of oil leakage is effectively reduced.
Description
technical field [0001] The invention belongs to the field of excavators, and in particular relates to an excavator bucket oil cylinder. Background technique [0002] The bucket cylinder in the excavator is composed of a bucket cylinder, a guide sleeve and a piston rod. The guide sleeve is installed at the front end of the bucket cylinder and cooperates with the piston rod to have the functions of guiding, sealing oil and limiting stroke. Because the oil seal between the guide sleeves will be worn and deformed due to long-term use, it will cause the oil leakage of the guide sleeves. The reason for the oil leakage of the guide sleeves is mainly due to the unreasonable design of the sealing parts. Invention content: [0003] In order to solve the above problems, the present invention [0004] An excavator bucket oil cylinder is provided, the bucket oil cylinder includes a bucket cylinder cylinder 1, a guide sleeve 2, a piston rod 3, and the guide sleeve 2 is installed on the...
