On the right side of the fixed seat 7 on the left, the right end of the guide rod 9 is slidably connected to the circular hole of the fixed seat 7 on the right, and the left end of the reciprocating screw 8 is provided with a bevel gear 10. The outer side of the rotating tube 4 is rotatably connected to the bevel gear 2 11 through the bearing 3. The bevel gear 10 is meshed with the bevel gear 2 11. The upper side of the bevel gear 2 11 is fixedly connected to the lower side of the connecting seat 1 through a symmetrically distributed fixing rod 12. A drive motor 16 is provided on the upper side of the connecting seat 1. The input end of the drive motor 16 is electrically connected to the output end of the single-chip microcomputer 2. The output shaft of the drive motor 16 is fixedly connected to the upper end of the drive shaft 13. A symmetrically distributed mounting bracket 18 is provided on the upper side of the connecting seat 1. The device is fixed to the external drilling fluid emulsion reducer preparation device with bolts through the mounting bracket 18. Then, the feed pipe 3 is connected to the external drilling fluid emulsion fluid loss agent preparation feed pipe. When adding materials during the drilling fluid emulsion fluid loss agent preparation process, the single chip computer 2 opens the solenoid valve 17 to release the raw material blockage of the feed pipe 3, so that the drilling fluid emulsion fluid loss agent raw material is added through the feed pipe 3, the rotating pipe 4, the bellows 5 and the discharge pipe 6. During this process, the single chip computer 2 starts the drive motor 16 so that its output shaft drives the gear 14 to rotate through the drive shaft 13. The gear 14 is engaged with the gear 2 15, so that the rotating pipe 4 indirectly drives the discharge pipe 6 to rotate horizontally around the center of the feed pipe 3, thereby improving the feeding coverage of the device to the external drilling fluid emulsion fluid loss agent preparation device, thereby improving the device to In order to improve the feeding uniformity of the emulsion fluid loss reducer for drilling fluid, during the rotation of the rotating tube 4, the bevel gear 2 11 is fixed to the connecting seat 1 through the fixed rod 12, and is meshed and connected with the bevel gear 2 11 through the bevel gear 10, thereby rotating the reciprocating screw 8.

During this process, the fixed seat 7 on the right side slides adaptively along the guide rod 9 through the circular hole, thereby avoiding horizontal rotation during the horizontal movement of the feeding pipe 6. The device increases the feeding coverage of the feeding part through the transmission element.This improves the uniformity of raw material feeding during the production of emulsion fluid loss reducers for drilling fluids;

When feeding is performed during the preparation process of the emulsion fluid loss reducer for drilling fluid, the single chip computer 2 opens the solenoid valve 17 to release the raw material blockage of the feeding pipe 3, so that the raw material of the emulsion fluid loss reducer for drilling fluid is fed through the feeding pipe 3, the rotating pipe 4, the bellows 5 and the discharge pipe 6. During this process, the single chip computer 2 starts the driving motor 16 so that its output shaft drives the gear 14 to rotate through the driving shaft 13. The gear 14 is engaged with the gear 2 15, so that the rotating pipe 4 indirectly drives the discharge pipe 6 to rotate around the feeding pipe 3. The center of the pipe rotates horizontally, thereby improving the feeding coverage of the device to the external drilling fluid emulsion fluid loss reducer preparation device, and thus improving the feeding uniformity of the device to the drilling fluid emulsion fluid loss reducer. During the rotation of the rotating pipe 4, the bevel gear 2 11 is fixed to the connecting seat 1 through the fixed rod 12, and is meshed and connected with the bevel gear 2 11 through the bevel gear 10, so that the reciprocating screw 8 rotates. During the rotation of the reciprocating screw 8, the fixed seat 7 on the right drives the discharge pipe 6 to alternately approach and move away from the center of the feed pipe 3 through the threaded connection, thereby further improving the feeding coverage of the device and further improving the feeding uniformity of the device to the drilling fluid emulsion fluid loss reducer.
