Abstract

The invention discloses a vibration advancing and loading operation control system for a loader. The system comprises a steady-state hydraulic oil pump, a steady-state oil passage and a hydraulic cylinder, wherein the steady-state hydraulic oil pump is connected with the steady-state oil passage; the system is also provided with a pulsation hydraulic oil pump, a vibrating oil passage, a master oil passage, an instruction input device, a programmable logic controller (PLC) and a contactor, wherein the pulsation hydraulic oil pump is connected with the vibrating oil passage; the vibrating oil passage and the steady-state oil passage are connected in parallel and then connected with the master oil passage; the master oil passage is connected with the hydraulic cylinder; the pulsation hydraulic oil pump and the steady-state hydraulic oil pump are respectively connected with a hydraulic oil tank; and the instruction input device, the PLC and the contactor are sequentially connected with the pulsation hydraulic oil pump. The system can fully exert the rated advancing force of the loader and save energy.

Description

technical field [0001] The invention relates to a loader tunneling loading system, in particular to a loader vibration tunneling loading operation control system. Background technique [0002] Existing loaders often cannot give full play to their rated breakout force during the loading process. The main reason is that when the soil is squeezed, the soil will be compacted, so a greater breakout force needs to be added to achieve its Soil fragmentation. Most of the energy is used to overcome the frictional resistance between the bucket and the soil. High energy consumption. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a loader vibration excavation that can give full play to the rated breakout force and save energy in view of the problem that the loader often cannot fully exert its rated breakout force and high energy consumption during the loading process. Hydraulic control system for loading operation. [0...
