The reverse circulation drilling rig is mainly composed of the following parts
1. Hydraulic oil pump: dual connection, large displacement pump provides power for the power head, small displacement pump is a four-foot cylinder, lifting mast cylinder, afterburner/lift lifting cylinder is energized.
2. Four legs: the reverse circulation drilling rig equipment consists of a hydraulic cylinder and a fixed frame. The level of the body can be adjusted at the work site to support and stabilize the body.
3. Mast: The frame structure is welded by huge steel pipe, channel steel and angle steel. The inner grooves of the channel steel on both sides are used as the power head to move up and down to ensure the verticality of the hole. The ups and downs of the well are completed by hydraulic cylinders.
4. Power head: The mechanism using gear reducer has a large diameter mandrel in the middle of the low speed shaft. The upper end of the mandrel can be connected to the hose connection of the concrete pouring equipment to inject concrete; the lower end of the mandrel is connected to the drill rod and the drill bit through the blue plate. The high-speed shaft is driven by a high-torque hydraulic motor.
