Referring to fig. 1, 2 and 3, in order to provide a drip medicine adding device for an oilfield wellhead according to an embodiment of the present invention, as shown in fig. 1 and 2, the device includes a reciprocating medicine adding mechanism, the reciprocating medicine adding mechanism includes a plunger 1 and a reset elastic assembly, and the top of the plunger 1 is connected with a force-bearing component; the stress component is used for receiving pressure from the oil well rope hanger 14 during downward movement so as to drive the plunger 1 to move downward to realize dosing; the reset elastic component is used for driving the plunger to move upwards to suck the medicine when the oil well rope hanger 14 moves upwards.
Further, the reciprocating type medicine adding mechanism further comprises a cylinder body 2, and the lower part of the plunger 1 is located in the cylinder body 2; the upper part of the cylinder body 2 is connected with a first fixing clamping table 3 arranged along the circumferential direction of the cylinder body, and a second fixing clamping table 4 is arranged on the plunger 1 along the circumferential direction of the plunger; the reset elastic assembly comprises a reset spring 5, and the reset spring 5 is sleeved outside the plunger 1 and is positioned between the first fixing clamping table 3 and the second fixing clamping table 4. It is contemplated that the return spring may be selected from other arrangements that allow for a spring connection. The sub-unit connection of cylinder body 2 has inlet pipe 6 and arranges material pipe 7, inlet pipe 6 with arrange and be connected with check valve 8 on the material pipe 7 respectively. The medium flow direction of the one-way valve 8 on the feeding pipe 6 is towards the cylinder body, and the medium flow direction of the one-way valve 8 on the discharging pipe 7 is towards the outside of the cylinder body. In order to facilitate the installation of the reciprocating type dosing mechanism, the cylinder body 2 is connected with a fixing plate 9, and the fixing plate is used for being connected with a fixed object at the wellhead of an oil field. The fixture is a large flange of an oil field wellhead.
Further, the top of the plunger 1 is connected with a cross rod 10, and the stress component is a stress rod 11 which is connected with the cross rod and is longitudinally arranged. The cross rod 10 is provided with a through hole 12 which penetrates through the cross rod from top to bottom, a nut 13 is connected to the position, opposite to the through hole 12, of the cross rod 10, an external thread is formed in the outer side surface of the stress rod 11, and the stress rod 11 is connected with the nut 13 through the external thread. The contact distance between the stress rod and the self oil well rope hanger is changed by adjusting the length of the stress rod 11 which relatively extends out of the upper part of the nut 13, so that the stroke of the reciprocating type dosing mechanism is adjusted.
The polished rod eye and the polished rod are rigidly connected together, so an adjusting screw on the cross rod at the upper end of the plunger can also directly correspond to the polished rod eye and a force transmission part on the polished rod; the stress component receives the pressure from the oil well rope hanger when moving downwards through the clamp.
As shown in fig. 3, the present application provides an oil well polished rod eye 14 which is a connection device of a horse head 15 and a polished rod 16.
