The high-pressure water supply unit 1 comprises a first motor, a coupler and a water pump which are sequentially connected together, and the water outlet end of the water pump is connected with the outer end of the horizontal water inlet channel 7 through a high-pressure rubber pipe 4. The connecting point of the horizontal water inlet channel 7 and the vertical water inlet channel 8 is positioned above the bottom end of the vertical water inlet channel 8. The inner diameter of the vertical water inlet channel 8 is larger than that of the horizontal discharging channel 9. Still include host computer casing 14 and abrasive tank installation casing 15, high pressure water supply unit 1 is fixed in host computer casing 14, the abrasive material is supplied with mixed unit and is fixed in abrasive tank installation casing 15, second motor 13 passes through the bolt fastening on abrasive tank installation casing 15, the universal wheel of predetermineeing quantity has been installed respectively to host computer casing 14 and abrasive tank installation casing 15 bottom. And the electric wire between the switch I2 and the first motor and the electric wires between the switch II 16 and the switch III 17 and the second motor are respectively and fixedly connected to the periphery of the adjacent high-pressure rubber hose 4 through connecting pieces.

During the use, only need single operation can, operating personnel handheld spray gun 3, press switch I2 earlier, start first motor in order to produce the high pressure water, press switch II 16 again, make out sand valve 12 open under the drive of second motor, the high pressure water gets into horizontal water inlet channel 7, after 7 comes out from horizontal water inlet channel, partial high pressure water directly gets into horizontal discharging channel 9, partly through vertical water inlet channel 8 get into in abrasive material jar 5, the abrasive material that gets into in the abrasive material jar 5 with the abrasive material in the abrasive material jar 5 passes through sand outlet channel 11 and dashes to horizontal discharging channel 9 in, thereby accomplish the mixture of high pressure water and abrasive material, the mixture that comes out from horizontal discharging channel 9 passes through high-pressure rubber pipe and gets into spray gun 3, and then carry out the water cutting from spray gun 3 blowout. The water under high pressure and abrasive material spun proportion accessible set up different internal diameters to vertical inhalant canal 8 and horizontal discharging channel 9 and control, the internal diameter of vertical inhalant canal 8 will be greater than the internal diameter of horizontal discharging channel 9 and is comparatively reasonable in order to ensure the proportion of spun water under high pressure and abrasive material, set up horizontal inhalant canal 7 and the tie point of vertical inhalant canal 8 and can avoid the problem that the water under high pressure that comes out by horizontal inhalant canal 7 most directly rushes into horizontal discharging channel 9 in the top of vertical inhalant canal 8 bottom, and then avoided getting into abrasive tank 5 by vertical inhalant canal 8 the water under high pressure water yield too little.
When the water cutting operation needs to be stopped, an operator holding the spray gun 3 firstly presses the switch III to control the second motor 13 to rotate forwards, the second motor 13 drives the sand outlet valve 12 to be closed, the abrasive material supply is stopped, the high-pressure water supply is continued, and after the abrasive material in the high-pressure rubber pipe 4 between the abrasive material supply mixing unit and the spray gun 3 is flushed by the high-pressure water (generally for 2 minutes), the operator controls the first motor to stop rotating through the switch I2 to stop the supply of the high-pressure water.
This kind of water cutting machine realizes and has made things convenient for the operating personnel of handheld spray gun 3 to control the supply of high pressure water and the supply of abrasive material respectively through the switch in spray gun department, whole process only needs one-man operation, make operating personnel can utilize the high pressure water to wash clean the interior remaining abrasive material of high pressure rubber pipe through closing the abrasive material supply earlier and then closing the mode that the high pressure water was supplied with at the longer time of the distance between water cutting machine and the spray gun, and then avoid the long high pressure rubber pipe between water cutting machine and the spray gun to take place to block up because of remaining the abrasive material, one-man operation, it is practical convenient.
The operation mode of firstly introducing water and then adding sand can not only enable the starting process of water cutting to be smoother, but also reserve time for preparing and adjusting the spray gun for an operator before adding sand after introducing water, and reduce the waste of grinding materials at the initial starting stage.
The high-pressure water supply unit 1 and the abrasive material supply and mixing unit are respectively installed in different shells through bolts and connected through high-pressure rubber pipes, and the bottoms of the main machine shell 14 and the abrasive material tank installation shell 15 are respectively provided with a preset number of universal wheels. The structure enables the water cutting machine to be more flexible and convenient to move integrally, the abrasive material supply and mixing unit can be moved independently, and when the heavy high-pressure water supply unit 1 is not convenient to move, the abrasive material supply and mixing unit can be moved independently, so that the working range of the water cutting machine can be prolonged. Moving the abrasive supply and mixing unit independently also brings it closer to the cutting site, thereby reducing the distance between the sanding site and the cutting site and saving abrasive. The water cutting machine with the structure has more obvious advantages in the complex environment in the well.
The electric wire between switch I2 and the first motor and the electric wire between switch II 16 and switch III 17 and the second motor are respectively through connecting piece fixed connection in 4 outsiders of neighbouring high-pressure rubber pipe, can avoid the electric wire too in disorder, drag each other and beat the problem that influences water cutting machine and use. The provision of the manual spindle 18 enables the sand valve 12 to be manually closed in the event of a circuit failure, thereby stopping the supply of abrasive. The manual rotating shaft 18 can be easily rotated by an operator in a labor-saving manner by inserting rods, pipes and the like into through holes formed in the manual rotating shaft 18, so that the sand valve 12 can be easily closed.
In short, the above description is only a preferred embodiment of the present invention, and all the equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the scope of the present invention.
