The technical solution adopted by the present invention to solve the technical problems is：On existing conventional oil well pump architecture basics,
It is upper travelling ball cover and upward-traveling valves connector between one, device can strike-off on scrape exchange device, make the sand in plunger upper part crude oil
Grain cannot enter between plunger and pump barrel, oil well pump card machine crash caused by solving the problems, such as the sand sedimentation in crude oil, and energy
Plunger and pump barrel are protected, plays the role of increasing service life, achieving the purpose that, which reduces failure, improves oil recovery efficiency.
Exchange device is scraped on described to be made of sand hole straight coupling and scraper rings.
The sand hole straight coupling is straight-through for tubulose, and upper port is equipped with upper screw socket；Lower port is equipped with lower screw socket；Middle part is equipped with
Cutter groove is equipped with back sand hole at cutter groove.
The scraper rings are circular ring shape, are equipped with knife circumferential weld, collapse out circumferential weld when being easily installed, collar extension is made to magnify；Ring muscle
Section is in prismatic, and the low outside diameter wall of inner diameter wall is high, forms two blades up and down.
The sand hole straight coupling and scraper rings are combined as：Scraper rings are collapsed to the cutter groove opened and be nested in sand hole straight coupling
In.
The beneficial effects of the invention are as follows；The effect that exchange device is scraped on because solves sand sedimentation in plunger crude oil suitable for reading
Caused by card machine crash problem, improve rate of pumping, increase oil pumping yield；Failure rate is reduced, maintenance personnel is reduced；Saving is matched
Part consumptive material；Improve service life；Improve the working efficiency and oil recovery economic benefit of oil well pump.
