Abstract

The embodiment of the invention provides an auxiliary adjusting system, an excavator and excavating equipment, and relates to the field of engineering machinery. The auxiliary adjusting system comprises a first connecting pipe and a first pilot overflow valve arranged on the first connecting pipe. One end of the first connecting pipe is used for communicating with a hydraulic pump, the other end of the first connecting pipe is used for communicating with a preset accessory, and the first pilot overflow valve is used for limiting the pressure value of hydraulic oil flowing from the hydraulic pump to the preset accessory. By means of the auxiliary adjusting system, the pressure value of the hydraulic oil flowing to the preset accessory can be more accurate, and therefore normal operation ofthe preset accessory is achieved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an auxiliary adjustment system, an excavator and excavating equipment. Background technique [0002] The excavator auxiliary adjustment system is a system used to expand the functions of the excavator. The excavator can be connected with external attachments through the auxiliary adjustment system. The attachments can be hydraulic shears, breakers, lawn mowers, etc., so that The excavator can be adapted to a variety of operating scenarios. However, different attachments have different working pressures. Therefore, it is necessary to adjust the pressure of the hydraulic oil flowing to the preset attachment according to different attachments, so as to meet the normal use of the attachment. However, the adjustment accuracy of the traditional auxiliary adjustment system is low, resulting in that after replacing different attachments, the replaced attachments cannot work normally...
