[0021] A limiting plate 10 is rotatably mounted on the inner wall of the circulation tube 2, a rotating plate 12 is fixedly mounted on the surface of the limiting plate 10, and a push rod 20 is fixedly mounted on the surface of the rotating plate 12. The rotating plate 12 is rotated to drive the limiting plate 10 to rotate, and the gap between the limiting plate 10 and the circulation tube 2 is controlled to adjust the flow rate of the medicine.

[0022] A limit strip 13 is slidably mounted on the surface of the circulation tube 2, a plurality of push blocks 14 are fixedly mounted on the surface of the limit strip 13, a plurality of fixed blocks 11 are fixedly mounted on the surface of the rotating plate 12, a long rod 18 is slidably mounted on the surface of the mixing chamber 1, the long rod 18 passes through the limit strip 13 and a spring is arranged between the long rod 18 and the limit strip 13, a baffle 19 is fixedly mounted on the surface of the long rod 18, under the push of the baffle 19 and the traction of the spring, the three limit strips 13 push the corresponding rotating plates 12 to rotate, so that the flow limiting plates 10 in the three circulation tubes 2 are closed one after another.

[0023] A transparent tube 5 is fixedly installed at the bottom of the liquid storage tank 3. The interior of the transparent tube 5 is connected to the interior of the liquid storage tank 3. The transparent tube 5 is arranged in an L shape. A part of the medicine liquid in the liquid storage tank 3 flows into the transparent tube 5. The remaining amount of medicine in the liquid storage tank 3 is judged by the liquid level height in the transparent tube 5.

[0024] A docking port 9 is fixedly installed at one end of the delivery pipe 8 away from the liquid pump 6. A plurality of telescopic rods 7 are hinged on the surface of the mixing chamber 1.

When an emergency occurs in the device, such as a failure of the motor 15 or the liquid pump 6, the three liquid storage tanks 3 can be quickly closed at the same time to prevent the agent in the liquid storage tank 3 from continuing to flow out and causing the failure to further deteriorate. The moving long rod 18 drives the baffle 19 to move, and the moving baffle 19 contacts and pushes the limit bar 13 to move. When the limit bar 13 moves, it drives the surface push block 14 to move.

The rotating fixed block 11 drives the rotating plate 12 to rotate and close the limiting plate 10, so that the agent in the liquid storage tank 3 stops flowing into the mixing chamber 1, which is convenient for the staff to check and repair.

[0027] After the delivery pipe 8 is connected to the drilling equipment through the docking port 9, the telescopic rod 7 will support the delivery pipe 8 to prevent the delivery pipe 8 from bending and folding during operation, which would affect the uniform flow of the medicine in the delivery pipe 8. The telescopic rod 7 adjusts its length according to the tension and relaxation of the delivery pipe 8 and covers around the delivery pipe 8 to protect the delivery pipe 8 and prevent the delivery pipe 8 from being hit during operation and affecting the delivery efficiency of the medicine.
