The invention discloses a hydraulic control circuit for a vibrating motor and telescopic screeding and vibrating motors of a paver. The hydraulic control circuit comprises a hydraulic pump, a three-way valve, the vibrating motor, the left telescopic motor, the right telescopic motor, a through-wall board I and a through-wall board II, wherein an oil absorption body is connected with an oil inlet P1 of the hydraulic pump; a working oil port A1 of the hydraulic pump is connected with an oil inlet P2 of the three-way valve; a working oil port A2 of the three-way valve is connected with the through-wall board I; the through-wall board I is connected with an oil inlet P3 of the left telescopic motor, an oil return port A3 of the left telescopic motor, a casing oil return port T3 of the left telescopic motor and the through-wall board II; the through-wall board II is connected with an oil inlet P4 of the right telescopic motor, an oil return port A4 of the right telescopic motor, a casing oil return port T4 of the right telescopic motor and a working oil port C1 of the hydraulic pump; and another working oil port B2 of the three-way valve is connected with the oil inlet P5 of the vibrating motor. The hydraulic control circuit is simple in structure and low in cost.
Description
technical field [0001] The invention relates to the technical field of paver hydraulic systems, in particular to a hydraulic control circuit of a paver vibrating motor and a telescopic screed vibrating motor. Background technique [0002] The paver is a construction equipment mainly used for paving various materials on the base and surface of the road. During use, when the width of the road surface changes, a telescopic motor is required. When the road width is constant, a vibration system is required. However, the full hydraulic paver vibration and telescopic screed vibration circuit in the market is basically blank and cannot meet the requirements. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings in the above-mentioned prior art and provide a hydraulic control circuit for a paver vibrating motor and a telescopic screed vibrating motor. The hydraulic control circuit uses a three-way valve to connect the telescopic s...
