Wherein, 1, shell, 2, inner casing, 3, hydraulic power unit, 4, jack, 5, tubing, 6, buckle, 7, draw-in groove, 8, soil layer, 9, Rectangular saw-tooth, 10, hinge, 11, Chuan Dao.

Specific embodiment

In conjunction with accompanying drawing, the utility model is described in further details.

As illustrated, a kind of push type push pipe head, described push type push pipe head include shell 1, inner casing 2, propulsion dress Put and tubing 5, described propulsion plant includes hydraulic power unit 3 and jack 4, hydraulic power unit 3 is fixing with the left end of jack 4 even Connect, shell 1 and inner casing 2 are cylindrical shape, and the front end of shell 1 is provided with sawtooth, and the front end of inner casing 2 is inserted in inside shell 1, and inner casing 2 inner bottom are provided with propulsion plant, and described shell 1 front end is provided with sawtooth, and described tubing 5 front end is inserted in inside inner casing 2, rear end sets There is propulsion plant, described shell 1 interior lower end is provided with buckle 6, the upper and lower ends of the front end of described inner casing 2 are equipped with draw-in groove 7, institute Shape and the size of stating buckle 6 are consistent with the shape of draw-in groove 7 and size, and described shell 1 is by two diameter identicals half Cylinder is docking together and combines, and communicates inside two semicircular cylinders, and is equipped with rectangular saw-tooth 9 on two semicircular cylinders, passes through Two semicircular cylinders of snapping that mutually stagger of rectangular saw-tooth 9 on two semicircular cylinders link together, and two semicircular cylinders are also by conjunction Page 10 is attached, and wearing 11 is screw passage, wears and can be inserted into steel screw rod in 11, and the described quantity wearing 11 is 3, and 3 Ge Chuan roads 11 equidistantly distribute in rectangular saw-tooth 9, and the right-hand member of described jack 4 is provided with top, in described top and shell 1 The distance between circle lower end is less than the height of buckle 6.

Embodiment：During using the utility model, the hydraulic power unit 3 in inner casing 2 is operated, and drives jack 4 to push away forward Enter, the top on jack 4 in progradation runs into buckle 6, proceed advance work, buckle 6 stress, drive shell 1 to Front propulsion, the sawtooth of shell 1 front end enters underground layer 8, carry out advance work, then carry out labor cleaning soil slag, then with tubing 5 The propulsion plant connecting carries out advancing work, and propulsion plant drives tubing 5 to push ahead, and tubing 5 pushes up the hydraulic pump in inner casing 2 Stand 3, because hydraulic power unit 3 is fixed on inner casing 2, so hydraulic power unit 3 stress carries out advancing work, thus driving shell 1 to enter Row propulsion work.In the utility model, the diameter of shell 1 can be changed within the specific limits, the rectangle on two semicircular cylinders Sawtooth 9 Shang Chuan road 11 can carry out mutually forming a passage so that steel screw rod penetrates 11 formation leads to fetching Carry out screwing tight work, the docking position that the different diameter specifications of needs can be to two semicircular cylinder Shang Chuan roads 11 from each other in road Put and be adjusted, on such as one semicircular cylinder outermost end wear 11 can with another semicircular cylinder outermost end to wear 11 right Connect, 11 can also dock with wearing of innermost end on another semicircular cylinder or centre position.
