Further improvement as technique scheme:
The center of described plate respect thereto is arranged outwardly, and the upper end of plate is with flange, and the center of flange respect thereto stretches out, and with through jack on plate, the lower end of plate is with multiple separate slot, and with slot on flange, slot and jack are to corresponding.
Described jack is mounting hole structure, and slot is U-shaped structure.
The soffit of described base is with the first annular flange flange.
The bottom diameter of described taper sheath is less than the internal diameter of the cover that fetches earth.
Described taper sheath is volute spring, and the spring wire cross section of described volute spring is rectangular configuration.
The two ends of described handle are respectively with through hole.
The two ends of described connecting plate with arranging installing hole more, and the end of connecting plate is inserted in the periphery mounting groove of base, with the locking hole of through described mounting groove on base.
The soffit of described guide holder is with the second annular flange flange.
Beneficial effect of the present invention is as follows:
Structure of the present invention is simple, reasonable in design; Arrange and expand outwardly the plate of structure and the annular flange flange of base lower surface, avoid base to rotate relative to ground, improve stable connection, improve the operating efficiency of the sample that fetches earth; Connect taper sheath in the lower end of the cover that fetches earth, avoid soil sample to depart from the cover that fetches earth, realize primary sample, improve sampling efficiency; Structure of the present invention is simple, reasonable in design.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the soil sampler of the present embodiment, comprise annular base 1, the center of base 1 is fixed with guide holder 2 by connecting plate 6, the central slide device of guide holder 2 fetches earth bar 4, the bar 4 that fetches earth is that upper end is with the structure of screw mandrel 41 lower end with the cover 42 that fetches earth, screw mandrel 41 spiral is connected in screw rodb base 3, screw rodb base 3 is fixedly connected with by many fixed bars 5 with annular base 1, the upper end band jug 44 of screw mandrel 41, the circumferential lateral surface of base 1 is fixed with plate 13, and the Central Symmetry of plate 13 respect thereto 1 is arranged, plate 13 is towards the below of base 1.
As shown in Figure 3, Figure 4, the center of plate 13 respect thereto 1 is arranged outwardly, the upper end of plate 13 is with flange 14, the center of flange 14 respect thereto 1 stretches out, and with through jack 131 on plate 13, the lower end of plate 13 is with multiple separate slot 132, with slot 141 on flange 14, slot 141 and jack 131 are to corresponding, and jack 131 is mounting hole structure, and slot 141 is U-shaped structure.
As shown in Figure 3, the soffit of base 1 is with the first annular flange flange 12.
As shown in Figure 5, the bottom diameter that the lower end of the cover 42 that fetches earth is connected with taper sheath 43 taper sheath 43 is less than the internal diameter of the cover 42 that fetches earth, and taper sheath 43 is volute spring, and the spring wire cross section of volute spring is rectangular configuration; The two ends of handle 44 are respectively with through hole 441.
As shown in Figure 1, the two ends of connecting plate 6 are with many row's installing holes 61, the end of connecting plate 6 is inserted in the periphery mounting groove 11 of base 1, with the locking hole 15 of through mounting groove 11 on base 1, between connecting plate 6 and base 1, fitting operation is convenient, stable connection, the adjustable installing space of many row's installing holes 61, realizes the connection between the guide holder 2 of different size and base 1.
As shown in Figure 2, the soffit of guide holder 2 is with the second annular flange flange 21.
When the present invention uses, base 1 and earth surface, base 1 is connected with ground by the jack 131 of the slot 141 and plate 13 that run through flange 14 by screw, in screw screwing operations, plate 13 inserts underground, first annular flange flange 12, second annular flange flange 21 inserts underground simultaneously, thus avoids base 1 ground rotation relatively completely.When needs fast fetching earth sample, can not need by screw, directly base 1 be compressed ground, in compaction process, plate 13 expands insertion laterally, and its Cat-in resisting force is little, and can prevent the disengaging between base 1 and ground when fetching earth; Swing handle 44 cover 42 that will fetch earth screws in underground, and taper sheath 43 1 aspect of cover 42 lower end of fetching earth can reduce the resistance fetched earth between cover 42 and ground, the coming off of sample when can avoid rollback on the other hand, thus realizes primary sample, and efficiency is high.
Structure of the present invention is simple, reasonable in design; Arrange and expand outwardly the plate of structure and the annular flange flange of base lower surface, avoid base to rotate relative to ground, improve stable connection, improve the operating efficiency of the sample that fetches earth; Connect taper sheath in the lower end of the cover that fetches earth, avoid soil sample to depart from the cover that fetches earth, realize primary sample, improve sampling efficiency; Structure of the present invention is simple, reasonable in design.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
