Abstract

The utility model relates to a novel earth drill, which comprises a drill bit, a drill rod, a horizontal handle and an end plug. The utility model is characterized in that a knife-edge of the front end of the drill bit forms a sawtooth shape; the drill rod is alternately provided with an inserting hole of the horizontal handle; the position of the horizontal handle can be adjusted according to the depth that an earth drill drills into the earth so that drilling is convenient; the end plug ensures that the tail end of the drill rod can not deform when an iron hammer is used for knocking the tail end of the earth drill so that the earth drill is pushed to be penetrated into a hard soil layer. The penetration of the front end of the earth drill towards soil is easy by the utility model, and the utility model is particularly suitable for heavy soil which is difficult to be penetrated by an ordinary earth drill. Used materials are stainless steel, so that light weight, hardness and sharpness are ensured, and corrosion can be prevented. Accordingly, frictional resistance when the utility model is penetrated in the soil layer can be prevented, and the pollution of a soil sample caused by rust is prevented. Simultaneously, the utility model has the advantages of firmness, durability, long service life, the accuracy guarantee of earth drilling, simple operation, strong practicability and convenient maintenance.

Description

Novel geotome

Technical field

The utility model belongs to a kind of agricultural land soil sampler, particularly a kind of novel geotome, and the soil sample that it is obtained is used for the detection of physicochemical property such as weight moisture capacity, soil nutrient, soil particle analysis, the soil sample that can get different depth.

Background technology

The detection of physicochemical property such as soil weight water percentage, soil nutrient, soil particle analysis is the important content in fields such as irrigation and water conservancy, pedology, hydraulic structure, adopting the soil sample of earth boring auger collection different depth little, simple to operate to the soil disturbance scope, is the indispensable instrument of association area mentioned above for a long time.Yet up to the present, the employed earth boring auger of people (non-fried dough twist row) chisel edge 3 is circular (referring to accompanying drawing 1), and is deeply difficult for sticking heavy soil.Simultaneously, it is material that present earth boring auger adopts cast iron more, body weight, not sharp, and easy-to-rust, iron rust have promptly increased the frictional resistance when going deep into soil layer, can produce soil sample again and pollute.Simultaneously, it is stifled that drilling rod end 1 is not established end, when knock earth boring auger end 1 with iron hammer, can make when promoting the deeply harder soil layer of earth boring auger that drilling rod is terminal to produce distortion.

The utility model content

The purpose of this utility model provides a kind of novel geotome, its easier difficult deep sticking heavy soil of common earth boring auger that gos deep into.Light, sharp, the corrosion resistant of while body.When knocking the earth boring auger end with iron hammer, can not make when promoting the deeply harder soil layer of earth boring auger that drilling rod is terminal to produce distortion.

The purpose of this utility model is achieved by the following technical solution: it comprises that drill bit, drilling rod, horizontal handle and end are stifled, it is characterized in that: the edge of a knife of drill bit tip is sawtooth pattern, establish a horizontal handle jack every a segment distance on the drilling rod, go deep into the position of the whole horizontal handle of depth-adjustment in the soil so that fetch earth according to earth boring auger.

Above-mentioned end is stifled to be connected the drilling rod end by screw thread and seccotine.

The utility model has the advantages that: can make earth boring auger more easily go deep into the difficult deep sticking heavy soil of common earth boring auger.The material that is adopted is a stainless steel, has guaranteed that promptly body is light, hard, sharp, can avoid corrosion again, thereby the frictional resistance when having avoided going deep into soil layer has also been avoided the pollution of rust to soil sample.End is stifled have been guaranteed to knock the earth boring auger end with iron hammer, can not make when promoting the deeply harder soil layer of earth boring auger that drilling rod is terminal to produce distortion.Simultaneously durable, long service life, the precision that fetches earth are secure, simple to operate, practical, easy to maintenance.

Description of drawings

Fig. 1 is existing earth boring auger structural representation.

Fig. 2 is a structural representation of the present utility model.

Embodiment

See Fig. 2, concrete structure is: material of the present utility model is a stainless steel, is drill bit 6 bottom, and the front end 3 of drill bit 6 is the sharp edge of a knife of sawtooth pattern, and welding drilling rod 2 above the drill bit all indicates scale gos deep into soil layer with indication drill bit leading edge the degree of depth on drill bit 6 and the drilling rod 2.Bore on the thick stick 2 at a certain distance (as 50cm) and establish a cross-drilled hole 7 and be used for installing horizontal handle 5, make when fetching earth the position that to adjust horizontal handle 5 according to the degree of depth that chisel edge 3 enters soil, so that operation.The drilling rod end is connected the steel end by screw thread with seccotine stifled 4, to guarantee knocking the earth boring auger end with iron hammer, can not make the drilling rod end not produce distortion when promoting the deeply harder soil layer of earth boring auger.During use, hold up in ground earth boring auger is vertical, can make earth boring auger front end 3 be deep into the needed degree of depth by pushing horizontal handle 5 when soil property is softer, when soil property is hard, it is stifled 4 to knock the end of drilling rod end with iron hammer, and the front end that promotes the earth boring auger drill bit enters into the needed degree of depth.Lift horizontal handle then and propose earth boring auger,, extract while can rotate if meet difficult situation about proposing.With the yi word pattern screwdriver soil sample in the drill bit is taken out then and be contained in sealing loan or the aluminium box.The design size of drilling rod, drill bit etc. can be adjusted as required.

Claims

1, a kind of novel geotome, it comprises that drill bit, drilling rod, horizontal handle and end are stifled, it is characterized in that: the edge of a knife of drill bit tip is sawtooth pattern, establishes a horizontal handle jack every a segment distance on the drilling rod.

2, novel geotome according to claim 1 is characterized in that: end is stifled by being threaded in the drilling rod end.
