As shown in Figure 3, the rod feeding module 3 is composed of a rod feeding main arm 31, a rod feeding main arm strut 32, a rod feeding auxiliary boom 33 and a manipulator bracket 34, and the two ends of the manipulator bracket 34 are fixedly connected with upper The manipulator 341 and the lower manipulator 342 are used to grasp the drill pipe; one end of the main arm 31 of the rod is hinged to the moving sleeve 27, and the other end of the main arm 31 of the rod is hinged to the bracket 34 of the manipulator; the main arm of the rod 32 is hinged. One end of one end is hinged with the lifting upper bracket 22, and the other end of the main arm pole 32 of the sending rod is hinged with the middle position of the main arm 31 of the sending rod; The other end of the arm 33 is hinged with the manipulator bracket 34 to ensure that the manipulator bracket 34 is lifted and moved in parallel to the upper support 22 . the

As shown in Figure 4, the energy-saving module 4 is composed of a box body 41, a counterweight body 42, a rack 43, a rack slide rail 44 and a sector gear 45, the box body 41 is fixedly connected with the base 1; the counterweight left pulley 46 is fixed on On the casing 41, the counterweight right pulley 47 is fixed on one end of the rack 43, and the counterweight body 42 can move up and down between the counterweight left pulley 46 and the counterweight right pulley 47; there is a roller 431 on the rack 43 to ensure that the rack 43 slides in the middle of the rack slide rail 44; the rack 43 engages with the sector gear 45; the sector gear 45 is hinged with the casing 41 through the gear support shaft 48.
