Problems solved by technology

[0002] At present, in order to reduce the cost and improve the stability of rotation, the excavators produced and used in the market, especially small excavators, mostly use two or one hydraulic cylinder to push the center of the digging arm to support the rotating shaft cylinder to complete the excavation process. The hydraulic cylinder pushes, so the rotation angle of the digging arm is less than 180 degrees, so that in actual operation, it cannot be rotated at will, and the position for digging and unloading is too small to achieve the best digging effect

Embodiment Construction

[0013] like figure 1 , 2 As shown in , 3, the present invention includes the digging arm supporting rotating shaft cylinder 7 of the excavator digging arm 8 installed, and the action wheel 14 that drives the digging arm supporting rotating shaft cylinder for rotating motion is fixedly installed on the digging arm supporting rotating shaft cylinder 7, Corresponding to the action wheel 14, a driving device for driving the action wheel 14 to rotate is arranged on the excavator.

[0014] like figure 1 , 3 As shown, in the above mechanism, one of the technical solutions adopted may be: the action wheel 14 is a rotating shaft cylinder gear fixedly installed on the rotating shaft cylinder supporting the digging arm. The driving device that drives the rotating shaft barrel gear 14 to rotate is: a rotating shaft is movably installed on the chassis 17; The rotating shaft barrel gears 14 mesh with each other, and one end of the hydraulic cylinder 16 is hinged on the drive gear 15, an...

Abstract

The invention relates to an improvement to the rotating structure of the excavator in order to expand the rotation range of the lifting arm of the excavator. There is an action wheel that drives the digging arm to support the rotating shaft cylinder for rotary motion. Corresponding to the action wheel, a driving device for driving the action wheel for rotary motion is provided on the excavator. The advantages of convenience, safety, reliability and high work efficiency.

Description

technical field [0001] The invention belongs to an improvement on the mechanical structure of the excavator, in particular to an improvement on the rotary structure of the excavator in order to expand the rotation range of the lifting arm of the excavator. Background technique [0002] At present, in order to reduce the cost and improve the stability of the rotation, the excavators produced and used in the market, especially the small excavators, mostly use two or one hydraulic cylinder to push the center of the digging arm to support the rotating shaft cylinder to complete the excavation process. The hydraulic cylinder pushes, so the rotation angle of the digging arm is less than 180 degrees, so that in actual operation, it cannot be rotated at will, and the position for digging and unloading is too small to achieve the best digging effect. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide a...
