The utility model content
The purpose of the utility model provides a kind of easy to assembly, time saving and energy saving, field location test stratified soil sample collecting apparatus that can not destroy the cell of origin soil body.
In order to accomplish above-mentioned purpose, the technical scheme that the utility model adopts is:
Field location test stratified soil sample collecting apparatus comprises impacting handle, drilling rod and drill bit, describedly impacts handle and drilling rod, drilling rod is fixing for being threaded with drill bit; Described drill bit is that periphery is provided with flange, and inwall is provided with the taper type hollow boring bit of boss; Described drilling rod is hollow tubular and on sidewall, has the bar shaped sample tap.
Comprise also being arranged on the extension rod that impacts between handle and the drilling rod that impact handle, extension rod is fixing through being threaded successively with drilling rod, described extension rod is provided with spanner flat on the lateral wall circumference.
The described top that impacts handle is provided with through hole, and taper knob is contained in the through hole, and described impacting is provided with outer silk connector on the handle, and the bearing pin through being arranged on the handle bottom and pin-and-hole fix with a connector outward.
The lateral wall of described drilling rod and extension rod is provided with rule.
The beneficial effect of the utility model is: each assembling position is fixing through being threaded successively; With drill bit is that periphery is provided with the taper type hollow boring bit that flange, inwall are provided with boss; Make the bit force point reach minimum with fetch earth resistance and can be thinner first watch of minimizing than common geotome; Destruction to the field soil body is little, and is easy to assembly, time saving and energy saving.

Embodiment
The utility model is a field location test stratified soil sample collecting apparatus; Each assembling position is fixing through being threaded successively; With drill bit is that periphery is provided with the taper type hollow boring bit that flange, inwall are provided with boss, makes the bit force point reach minimum with fetch earth resistance and can be thinner first watch than common geotome of minimizing, little to the destruction of the field soil body; Easy to assembly, time saving and energy saving.
Below in conjunction with accompanying drawing the utility model is further specified.
Specific embodiment; Extremely shown in Figure 5 like Fig. 1; Field location test stratified soil sample collecting apparatus comprises impacting handle 1, extension rod 4, drilling rod 2 and drill bit 3, impacts handle 1 by the one-shot forming of high-quality stainless steel material; The top that impacts handle 1 is provided with through hole; The stainless steel handle 9 of round bar shape is sleeved in the through hole, impacts bearing pin and pin-and-hole and the outer silk connector 10 of handle 1 through being arranged on its underpart and fixes, when outer silk connector 10 damages, only need extract bearing pin just externally a connector 10 change; Extension rod 4 is the stainless steel heavy wall one step shaping seamless pipe of hollow; One end of extension rod 4 is the internal thread connecting port; The other end of extension rod 4 is provided with outer silk connector, on extension rod 4 lateral wall circumference, is provided with the spanner flat 8 spanner assembly and disassemblies easy to use of groove-like; Drilling rod 2 is the stainless steel heavy wall one step shaping seamless pipe of hollow; The two ends of drilling rod 2 are provided with the internal thread connecting port; On the sidewall of drilling rod 2, adopt the molybdenum filament cutting machine accurately to have the bar shaped sample tap 5 of half flute profile; The size of sample tap 5 so both can guarantee can not drop out after the pedotheque of gathering is unearthed than the little 2mm of diameter of collection soil sample, can take out pedotheque easily again; Drill bit 3 is the hollow boring bit of taper type; Alloy steel by high-quality forms through the lathe Precision Machining; Drill bit 3 is provided with arc at the rear portion of its outer wall flange 6 makes the diameter of the maximum gauge of drill bit greater than drilling rod 2; Whole drawing out soil equipment in the time of can bearing soil and gather stressed; Be provided with the boss 7 of ring-type wedge shape tooth shape at the front end of drill bit 3 inwalls, make drill bit 3 stress points reach minimum, the destruction of the field soil body is diminished with fetch earth resistance and can be thinner first watch of minimizing than common geotome; And the boss 7 of the ring-type wedge shape tooth shape of protrusion drill bit 3 inwalls can make the earth pillar of collection attenuate and conveniently make the easily taking-up from drilling rod 2 of earth pillar of being got, and the afterbody of drill bit 3 is provided with outer silk connector; Impact handle 1, extension rod 4, drilling rod 2 and drill bit 3 and interfix through being threaded successively, on the lateral wall of drilling rod 2 and extension rod 4, be provided with rule.
