[0002] An additive used to increase the recovery rate of crude oil during oil drilling. Commonly used are polymer-type oil-displacing agents. For example, ultra-high molecular weight polyacrylamide, with a 0.05% aqueous solution, can penetrate into the oil layer and produce 20% to 30% more oil. Roughly, every kilogram of oil-displacing agent can produce 1,590 liters of more crude oil.

[0003] With the development of technology, automatic filling machines have been produced and put into use. Filling machines assist in filling materials, effectively reducing manpower and improving production efficiency. Various reagents can be filled through filling heads.

[0004] However, the existing filling heads often leak during use, and during long-term use, the liquid will be seriously wasted, resulting in increased costs. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model is provided with fixed columns, connecting rods, water retaining pads, baffles, water outlet grooves, water diversion grooves, baffles, springs and other components, and the baffles are pushed to drive the corresponding connecting rods and water retaining pads to move vertically downward along the corresponding fixed columns. At this time, the baffles are located below the water diversion grooves, and the displacing agent will enter the fixed columns along the water diversion grooves. At this time, the displacing agent will enter the water outlet grooves from the water diversion grooves, and thereby the displacing agent will be discharged. When no external force acts on the baffles, the spring will push the corresponding baffles to reset them under the action of its rebound force, and the water retaining plate will fit the corresponding fixed columns and block the water outlet grooves. At this time, the displacing agent cannot pass through the fixed columns, thereby achieving the effect of preventing the displacing agent from dripping through the fixed columns and their internal components.

[0015] 2.

At this time, the air pump is connected through the air pipe to form a negative pressure inside the liquid storage tube. The push rod will push the plug plate to contact and squeeze the liquid storage tube, and then pull the plug plate through the push rod to move horizontally along the liquid storage tube. At this time, the negative pressure increases, and the displacing agent is stored through the fixed column and its internal components. When the plug plate is pushed, the displacing agent will be discharged along the fixed column below and its internal components, thereby achieving the effect that the device can discharge the displacing agent through the horizontal movement of the plug plate.
