Screw thread 5 its width on drill bit 4 and capping screw assembly 3 peripheries become big gradually by little.
Drill bit 4 ends, on the 360 degree circumference, the equal angles concavo-convex bayonet socket 10 that distributing, the periphery of concavo-convex bayonet socket 10 is just to connect external screw thread 11 and attaching nut 12, and an end of attaching nut 12 is a plus thread, and the other end is a left-hand thread.
The center of capping screw assembly 3 is through holes 13, pass a capillary tube 14 in the through hole 13, sealing mat 15 is equipped with at the two ends of capillary tube 14, at the two ends of capping screw assembly 3, on the 360 degree circumference, the equal angles concavo-convex bayonet socket 16 that distributing, the periphery of concavo-convex bayonet socket 16 are to connect external screw thread 17, and wherein the connection external screw thread of an end is a plus thread, the connection external screw thread of the other end is a left-hand thread, end with plus thread has the attaching nut, and attaching nut's a end is a plus thread, and the other end is a left-hand thread.
The center of drilling rod 2 is through holes, and through hole passes a capillary tube, and an end capillaceous is equipped with sealing mat, and the other end capillaceous passes from the side of drilling rod 2.
The invention has the beneficial effects as follows, in drilling process, not carrying drilling tool just can increase drilling rod, can satisfy the sampling request of different depth, in pumping process, can reverse drilling tool and not destroy sealing effectiveness, in drilling process, the helical blade that adheres on the taper bit forms the single track curved-line thread path in soil, thereby need not broken soil, and utilize the width of helixseal blade that soil is pushed, play sealing function.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is an overall schematic of the present invention.
Fig. 2 is the drill bit structure front view.
Fig. 3 is concavo-convex bayonet socket joint design schematic diagram.
The specific embodiment
Fig. 1 is an overall schematic of the present invention: handle 1 assists people in manual mode drill bit 4 to be pierced in the soil, and handle 1 adopts the mode of concavo-convex bayonet coupling shown in Figure 3 to be connected with drilling rod 2.This connected mode can make drilling tool adapt to collection needs of different depth, gathers deeply more, and the drilling rod of needs is many more.Adopt bayonet socket butt joint screw fixed counter-rotating falling proof technique, make drilling tool under the forward or reverse state, can both keep the compactness that connects.Having guaranteed can not carry in drilling process to bore just can increase drilling rod, thereby can satisfy the sample requirement of different depth.Bayonet socket butt joint screw fixed counter-rotating falling proof technique is applied in the butt joint of each parts of the present invention.There is a through hole at the center of drilling rod 2, passes a capillary tube in the through hole, and an end capillaceous is equipped with sealing mat, compresses sealing function so that play with the linking of capping screw assembly 3 time.The other end capillaceous passes from the side of drilling rod 2.
Also there is a through hole 13 at capping screw assembly 3 centers, pass a capillary tube 14 in the through hole, and sealing mat 15 all is equipped with at the two ends of capillary tube 14.Axle such as one end of capping screw assembly 3 spiral, the other end is tapered cone-type spiral, waits axle head and drilling rod 2 butt joints, tapering point and drill bit 4 butt joints.Sealing mat capillaceous pushes mutually during butt joint, plays sealing function.Capping screw assembly 3 adopts tapered spiral and the special spiral that waits the axle spiral to combine is made up, the elastic deformation of axle spirals such as the extruding force that relies on tapered spiral to produce has guaranteed upper gas gas-insulated with a position of getting to the soil compression effect, utilization and soil guarantees can reverse drilling tool (carrying brill) and does not destroy sealing effectiveness in pumping process.Make capping screw assembly 3 form taper by the width that changes screw thread 5.
Fig. 2 is the drill bit structure front view: drill bit 4 is pyramidal structures completely, periphery at bullet has screw thread 5, the width of screw thread 5 changes, width near the sharp threaded one end 5 of awl is the narrowest, and the wideest near the screw thread of the drill bit other end, its wideest width is with the width of thread unanimity of the tapering point of capping screw assembly 3.There is a gas collection hole 6 side of drill bit 4 awl tails one end, and gas collection hole 6 outsides are filtered protector 9 in the outside of filter screen 8 with slip-type with filter screen 8.Gas collection hole 6 communicates with drill bit 4 axial holes, and a capillary tube 7 is arranged in the hole, and an end of capillary tube 7 is equipped with sealing mat.Drill bit 4 is to adopt concavo-convex bayonet coupling technology shown in Figure 3 with being connected of capping screw assembly 3, drill bit 4 ends, on the 360 degree circumference, the equal angles concavo-convex bayonet socket 10 that distributing, the periphery of concavo-convex bayonet socket 10 is just to connect external screw thread 11 and attaching nut 12, an end of attaching nut 12 is a plus thread, and the other end is a left-hand thread.Capping screw assembly 3 adopts the concavo-convex bayonet coupling technology identical with drill bit 4, and during butt joint, the concavo-convex bayonet socket of two parts is engaged.But, the external screw thread of two parts of butt joint but is one just, and one is anti-.When connecting two parts, the nut 12 as long as dextrorotation is dynamically connected just can connect together two parts.During dismounting, as long as counter-clockwise turn attaching nut 12.
