Automatic plunger catching and throwing device

The utility model relates to the technical field of plunger catching and throwing. The utility model relates to a plunger, in particular to an automatic plunger catching and throwing device. Gas wellgas control is adopted through the plunger automatic catching and throwing device. Automatic catching and putting of the plunger can be realized; control is stable, and operation is easy and convenient, automatic catching and putting of the plunger in each operation period are realized; the plunger is prevented from falling off to block an airflow channel and prevent hydrate from being frozen andblocked, the problems of plunger capturing and throwing in the large tubular column production well plunger gas lift technology are solved, stable production of gas well plunger gas lift drainage gasproduction is achieved, and meanwhile an automatic plunger capturing and throwing application scheme is provided for a conventional plunger gas lift well. 本实用新型涉及柱塞捕捉和投放技术领域，具体涉及一种柱塞自动捕捉投放装置，通过柱塞自动捕捉投放装置采用气井气体控制，能够实现柱塞自动捕捉和投放，控
