Abstract
The utility model provides a soil pouring type soil sampler, which comprises a rotary rod and a drill. The soil sampler is characterized in that a connector is fixedly connected to the lower end of the rotary rod, clamping pins are symmetrically and fixedly connected to the peripheral surface of the connector, a drill tube is connected to the upper end of the rotary cutter type drill, and the upper wall of the drill tube is provided with reverse 'L'-shaped connecting clamp slots in symmetry. The soil pouring type soil sampler has the advantages that soil collection and soil taking are integrated, both soil collection and soil taking are facilitated, and the soil sampler is convenient in demounting and convenient to carry.
Description
Technical field
The utility model belongs to a kind of sample acquisition machine, particularly a kind ofly falls native formula sample acquisition machine.
Background technology
Soil is one of important environmental factor of plant growth, also is the important component part of Agro-ecological System.The precondition of research soil is to obtain sufficient amount and the sample that can represent the survey region soil characteristic, so the soil sample collection just becomes the precondition of research soil.
Up to the present, domestic and international applied sample acquisition machine kind is more, but according to the integrated degree of gathering the back soil sample, can be divided into spiral collector and tubulose collector.Spiral collector profile is similar to spiral wood drill, utilizes rotation to go deep in the soil, and its disadvantage is that institute's soil sampling contacts with the external world fully, pollutes easily, uses few.The tubulose collection is divided into semi-enclosed and closed again; Wherein semi-enclosed collector comprises that mainly half opening formula earth boring auger (old-fashioned earth boring auger), cutting head extract hook (Eijkelkamp; Model 07.53.SA), semicircle traverse drill (New land mark in Beijing; XDB0302, XDB0404), heart type drill bit (Changzhou is general gloomy, the PST-75A drill bit); It is representative that the totally enclosed type collector produces standard manual soil sampler suit (model 01.11.SO) with Eijkelkamp ring-type sampling thief (model 07.53.SC) and Holland.
The disadvantage of spiral collector and semi-enclosed collector is: the soil sample of being gathered is prone to contact with extraneous soil; And mix peripheral soil; Particularly when sampling depth surpasses 30cm; This pollution is more obvious, gets but also need soil scrapper that the soil that collects is scraped, and is time-consuming.The advantage of the totally enclosed type collector of using at present, the pedotheque of being gathered separates with extraneous soil, can effectively avoid the pollution problem of sample, but that shortcoming is the taking-up of sample is extremely inconvenient, more obvious when sampling depth surpasses 30cm especially.
In sum, there are two big shortcomings in all sample acquisition machines of having used, and the one, because of the influence of drill bit structure, following drilling depth is limited; The 2nd, the soil sample that collects must be taken out with the instrument of one type of soil scrapper, wastes time and energy.These two reasons have restricted the speed that soil sample is gathered just, also become the biggest problem of soil investigation.
Summary of the invention
The purpose of the utility model provides a kind of native formula sample acquisition machine that falls, and is the collection of soil is combined as a whole with fetching earth, and can either conveniently gather, and also conveniently fetches earth.
The technical scheme that the utility model provides is following: it comprises dwang and drill bit, it is characterized in that: the lower end of dwang is fixed with connector, and symmetry is fixedly connected bayonet lock on the outer surface of connector; Rotary cutter type drill bit upper end connects bores tube, and anti-" L " type that has symmetry on the top barrel of brill tube connects draw-in groove.
The cutter that revolves of above-mentioned drill bit is formed by 4, revolves the cutter bottom and is flat sword, revolves preceding sword of cutter and cylinder cross-sectional direction at an angle; Revolving the preceding sword of cutter is arc attenuate shape gradually from the bottom to top.
Above-mentioned brill tube connects drill bit through spiral, and outside diameter is consistent with brill tube external diameter, and the drill bit internal diameter is less than boring tube internal diameter 1mm.
Above-mentioned dwang is " T " font, and its lower end is through the screw thread fixed connector.
The utility model has the advantages that: the collection of soil is combined as a whole with fetching earth, can either conveniently gathers, also conveniently fetch earth, be convenient to dismounting, easy to carry.

Fig. 2 is that dwang passes through the connector connecting structure synoptic diagram with the brill tube.
Fig. 3 be drill bit revolve the cutter synoptic diagram.
The A of Fig. 4 Fig. 3-A cut-open view.
Embodiment
See Fig. 1, concrete structure is following: the lower end of " T " font dwang 1 is through screw thread fixed connector 2, and symmetry is fixedly connected bayonet lock 2.1 on the outer surface of connector 2; Drill bit 4 upper ends of rotary cutter type are threaded and bore tube 3, and drill bit 4 can dismounting and change.Drill bit 4 external diameters are with to bore tube 3 external diameters consistent, and drill bit 4 internal diameters are less than boring tube 3 internal diameter 1mm, help burying and being unearthed of collector, and when collector rotates in soil, help soil sample and in boring tube, move and do not adhere to a brill inwall.Anti-" L " type that has symmetry on the top barrel of brill tube 3 connects draw-in groove 3.1, and the bayonet lock 2.1 of connector is installed on draw-in groove 3.1 interior realizations and connects, and when dextrorotation, does not throw off.
The cutter that revolves of drill bit is formed by 4, revolves the cutter bottom and is flat sword, revolves preceding sword 4-1 of cutter and cylinder cross-sectional direction at an angle, can guarantee the shear action to soil layer; Revolve the cutter rear portion and revolve with back a slice that sword 4-1 is provided with switching circular arc 4-2 before the cutter, revolve before the cutter sword 4-1, be convenient to separate the inside and outside soil of acquisition zone from the bottom to top for arc attenuate shape (seeing B portion among Fig. 4) gradually.
Use-pattern:
This sample acquisition machine according to shown in Figure 1, is installed dwang 1, connector 2, brill tube 3 and drill bit 4 in use successively; Aligning is adopted native position and is also applied certain pressure downwards to right rotation dwang 1, reaches to continue the rotation dwang when needing the degree of depth and upwards propose soil layer, to anticlockwise connector 2 and brill tube is left in 3 minutes; Inversion brill tube 3 can incline and soil sample; Clean out the surflaes at drill bit 4 positions again with pocket knife, repeat aforementioned operation afterwards, carry out the collection of next place soil sample.
Exemplary applications
The meadow soil in the brunisolic soil (Dong Ga town, Changtu County, Liaoning Province) in the brunisolic soil of the sample acquisition machine of the utility model low-yield land in Liaoning Province (old city town, Changtu County, Liaoning Province), middle high-yield field, the brown loam (Fuxin City Fu Meng county, Liaoning Province consolidates the town greatly) of middle-and-low-yielding fields, middle high-yield field (Agricultural University Of Shenyang scientific research and testing ground) has all carried out adopting the soil test.Application result shows, no matter is soil texture degree of tightness, and (soil moisture content≤35～50% are after promptly it's 4 hours is past rain) this collector all can use in certain soil moisture scope, can effectively penetrate hard plough sole.When manually gathering, collecting inclines soil sample required averaging time: being 0.5～1 minute during sampling depth 25～30cm, is 1～2 minute during sampling depth 50～60cm; When gathering 100cm is 2～4 minutes.
