Claims

[Scope of utility model registration request]

An air cylinder into which a loading hammer that can be raised and lowered is inserted and held; an air supply/exhaust valve fitted into the lower end of the air cylinder to hold the head of the cone rod and supply/exhaust air into the air cylinder; and an upper end of the air cylinder. an air supply control valve that is fitted into the air supply control valve and controls the supply and stop of compressed air supplied from the compressed air supply source to the air cylinder in conjunction with the vertical movement of the hammer; This automatic drop penetration system is characterized in that it is equipped with a hammer device and a portable cart that can stand up and move freely, allowing the hammer to fall naturally and then automatically rise and return using air pressure, thereby loading the cone rod with repeated falling impacts. testing machine.
