Control system having automatic earth shaking function and rotary drilling rig

Abstract

The invention relates to a control system having an automatic earth shaking function. The control system comprises a pilot pump, a main valve, a power head motor, an automatic earth shaking solenoid valve, and a controller; and the main valve and the power head motor are connected. An oil inlet of the automatic earth shaking solenoid valve is connected with the pilot pump; a first working port is connected with one end of the main valve by a first oil way; and a second working port is connected with the other end of the main valve by a second oil way. The automatic earth shaking solenoid valve contains a first electromagnet and a second electromagnet; the controller is connected with the first electromagnet and the second electromagnet electrically; and the controller controls the first electromagnet and the second electromagnet lose power repeatedly and alternately according to preset time intervals during the automatic earth shaking process. When the first electromagnet gets power, the oil inlet of the automatic earth shaking solenoid valve is in conduction with the first working port; and when the second electromagnet gets power, the oil inlet of the automatic earth shaking solenoid valve is in conduction with the second working port. According to the control system, the earth unloading efficiency is improved and the working load of the operators can be effectively reduced.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a control system with an automatic soil shaking function and a rotary drilling rig with the control system. Background technique [0002] When the rotary drilling rig performs drilling operations, it is necessary to unload the soil brought out from the drill bucket. In the prior art, the soil unloading method of the rotary drilling rig is to manually push the pilot handle left and right, control the opening of the main valve according to the direction and position of the pilot handle, and use the opening of the main valve to control the opening of the main pump The size of the power head motor, so as to control the forward and reverse rotation of the power head motor and the speed of rotation. . When the rotary drilling rig encounters a relatively clay layer during construction, the clay drilled into the drill bucket is difficult to remove. The operator needs to repeatedly...

Problems solved by technology

[0003] Repeatedly pulling the pilot handle for a long time will make the operator tired, and different operators have different frequencies of repeatedly pulling the pilot handle. If the pilot handle is pulled too violently, it is easy to cause damage to the pilot handle, and if the pilot handle is pulled too slowly , can not achieve the effect of shaking the soil, making the overall unloading efficiency low

Therefore prior art has increased workload to operator while also requiring higher operating level to operator
