Abstract

The utility model relates to an improved soil collecting drill, which comprises a drill bit, a drill rod, a horizontal handle and an end plug. The utility model is characterized in that the front end of the drill bit is provided with a flat-topped sharp knife-edge; the problems that a collected soil column forms a non-cylinder body and the uneven soil amount at different depth positions caused by that the uneven soil collecting of the leading end of the drill bit of the original soil collecting drill can be prevented; 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 the soil collecting drill is penetrated in soil; 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 soil collecting drill so that the soil collecting drill is pushed to be penetrated into a hard soil layer; simultaneously, the utility model has the advantages of firmness, durability, long service life, the guarantee of soil collecting accuracy, simple operation, strong practicability and convenient maintenance.

Description

Improved geotome

Technical field

The utility model belongs to a kind of agricultural land soil sampler, and obtained soil sample can be 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, particularly a kind of improved geotome.

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 2 of people (non-fried dough twist row) chisel edge 3 is circular (referring to accompanying drawing 1), and the earth pillar that causes taking out is the soil amount problem of non-uniform at non-cylinder, different depth place, thereby influences measuring accuracy.Simultaneously, it is material that present earth boring auger adopts cast iron more, body weight, not sharp, and easy-to-rust, rust has promptly increased the frictional resistance when going deep into soil layer, can produce soil sample again and pollute.Simultaneously, knock earth boring auger end 1 with iron hammer when taking soil sample, can make drilling rod terminal 1 produce distortion when promoting the deeply harder soil layer of earth boring auger.

The utility model content

The purpose of this utility model provides a kind of improved geotome, and is even thereby the soil sample that its takes out is the soil amount at uniform right cylinder, assurance different depth place, simultaneously light, sharp, the corrosion resistant of 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: chisel edge is the sharp edge of a knife of flat-top, 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 avoid the chisel edge of the original geotome irregular earth pillar that causes taking out that fetches earth to be the soil amount problem of non-uniform at non-cylinder, different depth place.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 the employed earth boring auger structural representations of present people.

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

Embodiment

See Fig. 2, concrete structure is: the utility model material is a stainless steel, is drill bit 3 bottom, and the front end 8 of drill bit 3 is the sharp edge of a knife of flat-top, welding drilling rod 2 above the drill bit 3.All indicate scale gos deep into soil layer with indication drill bit leading edge 8 the degree of depth on drill bit 3 and the drilling rod 2.Bore on the thick stick 2 at a certain distance (as 50cm) and establish a cross-drilled hole 5 and be used for installing horizontal handle 6, make when fetching earth the position that to adjust horizontal handle 6 according to the degree of depth that chisel edge 8 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 8 be deep into the needed degree of depth by pushing horizontal handle 6 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 8 that promotes the earth boring auger drill bit enters into the needed degree of depth.Lift horizontal handle 6 then and propose earth boring auger,, extract while can rotate if meet difficult situation about proposing.Soil sample in the drill bit is taken out by open-work 7 with the yi word pattern screwdriver 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 improved geotome, it comprises that drill bit, drilling rod, horizontal handle and end are stifled, it is characterized in that: chisel edge is the sharp edge of a knife of flat-top, establishes a horizontal handle jack every a segment distance on the drilling rod.

2, improved geotome according to claim 1 is characterized in that: end is stifled to be connected the drilling rod end by screw thread and seccotine.
