[0028] The cuttings receiving chamber 2 is equipped with a level gauge to collect the liquid level height inside the cuttings receiving chamber 2.

[0029] The hydraulic control tank 6 is connected to the oil inlet of the main hydraulic pump 3 and the auxiliary hydraulic pump 4, and supplies oil to the main hydraulic pump 3 and the auxiliary hydraulic pump 4.

[0030] The first chamber A and the second chamber B are both integrated on the skid base 8, and the top of the skid base 8 is provided with lifting lugs 15 for easy hoisting. The first chamber A and the second chamber B can be detachably connected (for example, the first chamber A and the second chamber B are fixed together by a connecting plate) and installed on the skid base 8 respectively; or they can be integrated and installed together on the skid base 8 to form a skid-mounted device.

[0031] The first chamber A includes a first upper chamber A1 and a first lower chamber A2. The cuttings receiving chamber 2 is located in the first upper chamber A1, and the swing tube 101 is located in the first lower chamber A2. The second chamber B includes a second upper chamber B1 and a second lower chamber B2. The main hydraulic pump 3, the auxiliary hydraulic pump 4, the valve block 5, and the hydraulic control tank 6 are located in the second upper chamber B1, and the conveying assembly 102 is located in the second lower chamber B2.

[0032] The control box 7 is connected to the main hydraulic pump 3, the auxiliary hydraulic pump 4, the valve block 5, and the level gauge in the rock cuttings receiving chamber 2 for automatic control.

[0033] like Figure 4 As shown, the conveying assembly 102 includes a first main hydraulic cylinder 1021, a second main hydraulic cylinder 1022, a first swing cylinder 1023, and a second swing cylinder 1024. The main hydraulic pump 3 and the auxiliary hydraulic pump 4 are both connected to a two-position four-way single-electro-controlled directional valve 9. The two-position four-way single-electro-controlled directional valve 9 is connected to two three-position four-way solenoid valves 10. One three-position four-way solenoid valve 10 is connected to both the first main hydraulic cylinder 1021 and the second main hydraulic cylinder 1022, and the other three-position four-way solenoid valve 10 is also connected to both the first main hydraulic cylinder 1021 and the second main hydraulic cylinder 1022. The main hydraulic pump 3 and the auxiliary hydraulic pump 4 are also connected to an accumulator 11. The swing pipe 101 can be connected to one of the two hydraulic cylinders under the drive of the two swing cylinders (using existing technology, such as the conveying mechanism of a concrete pump). A check valve 12 and a pressure gauge 13 are installed on the oil lines from the outlet of the main hydraulic pump 3 and the auxiliary hydraulic pump 4 to the two-position four-way single-electro-controlled directional valve 9 and the accumulator 11. An adjustable one-way throttle valve 14 is installed on the oil line near the accumulator 11. The high-pressure liquid output by the hydraulic pump enters the accumulator 11 through the one-way valve 12. The pressure value of the one-way throttle valve 14 can be adjusted by setting the pressure before the accumulator 11. When the pressure of the hydraulic fluid in the hydraulic process is lower than the normal working pressure, the high-pressure liquid in the accumulator 11 is supplied to the hydraulic process. The first main hydraulic cylinder 1021 and the second main hydraulic cylinder 1022 are each equipped with two one-way valves 12.

[0034] exist Figure 4In the middle, the DT5 of the two-position four-way single-electric directional valve 9 is energized, and the hydraulic pump is in an idle load state. Figure 5 In the middle, DT5 of the two-position four-way single-electro-controlled directional valve 9 is de-energized, while DT1 of the three-position four-way solenoid valve 10 (connected to the swing cylinder) and DT3 of the three-position four-way solenoid valve 10 (connected to the main hydraulic cylinder) are energized. The first swing cylinder 1023 extends to drive the swing tube 101, the second swing cylinder 1024 retracts, the first main hydraulic cylinder 1021 extends, and the second main hydraulic cylinder 1022 retracts. Figure 6 In the middle, DT5 of the two-position four-way single-electro-controlled directional valve 9 is de-energized, while DT2 of the three-position four-way solenoid valve 10 used to connect the swing cylinder and DT4 of the three-position four-way solenoid valve 10 used to connect the main hydraulic cylinder are energized. The second swing cylinder 1024 extends to drive the swing tube 101, the first swing cylinder 1023 retracts, the second main hydraulic cylinder 1022 extends, and the first main hydraulic cylinder 1021 retracts.

[0035] In this embodiment, the main hydraulic pump 3 has a power of 22KW, and the auxiliary hydraulic pump 4 has a power of 3KW. The cuttings receiving chamber 2 receives cuttings generated from various locations. A level gauge is installed inside the cuttings receiving chamber 2. When the liquid level in the cuttings receiving chamber 2 is lower than the set material level HSP1, the control box 7 only activates the auxiliary hydraulic pump 4 for liquid supply. At this time, the cuttings conveying speed slows down. When the liquid level in the cuttings receiving chamber 2 is higher than HSP1 but lower than HSP2, the control box 7 only activates the main hydraulic pump 3 for liquid supply. When the liquid level is higher than HSP2, the control box 7 will activate both the main hydraulic pump 3 and the auxiliary hydraulic pump 4 simultaneously for liquid supply. After multiple tests, the energy-saving effect is optimal when HSP1 is at 1 / 4 material level and HSP2 is at 3 / 4 material level.
