Abstract

The utility model discloses a manual rotary milling soil-sampling apparatus used for drilling and sampling soil in the original state. In the utility model, the upper part of an upright pole is provided with a handle, a fixing sleeve and a horizontal rail rod, the inside is provided with a soil pushing rod, and the lower end is provided with a soil sampler which comprises double sleeve barrels: a rotary outer barrel provided with milling gears and a fixed inner barrel. A rubber pad is arranged between a soil pushing disc in the inner barrel and the cover of the inner barrel. In operating time, the handle rotated by manpower drives the soil sampler to rotate, and to drill and sample the soil according to the milling cutter theory. The utility model thus has the advantages of labor saving, time saving, high efficiency and capacity of keeping the structure of the soil sample in the original state. The utility model has the maximal sampling depth of 1 m, and samples the soil 50 mm high with a diameter of 50 mm.

Description

Man-power rotary milling soil-taking apparatus

The utility model relates to a kind of manpower and revolves and mill the formula soil sampler, and available fourth drills through the original-state soil sample.

Though present paddle type mill soil sampler of the prior art has advantages such as simple in structure, easy and simple to handle, remain the effort, time-consuming, still need when efficient is low and dark soil layer fetches earth and could take out soil sample aside by the luoyang spade match-drill or with manually digging a hole.

The purpose of this utility model to design exactly a kind of laborsaving, save time, the efficient height, not only can independently carry out deep layer and fetch earth, and the manpower that can work under water revolves and mills the formula soil sampler.

The purpose of this utility model is achieved in that in the top of vertical rod dress handle, fixed cover and level holds up bar.Level holds up bar to be connected with pressure bearing with vertical rod, and when vertical rod was rotated, level held up bar not rotate; In the vertical rod pipe, adorn bulldozing rod; In the vertical rod bottom soil sampler is installed, there is mill teeth the soil sampler lower end, and soil sampler is made up of inside and outside two cylinders, and wherein inner core is a soil-containing tube, and inside and outside cover connects with pressure bearing.Inner core does not change, urceolus changes, bulldozing rod passes the inner core central small hole and leads in the vertical rod pipe, and bulldozing rod is connected with screw with the soil-shifting dish, and the soil-shifting dish places inner core, and and the inner core end face between adorn a rubber cushion, when soil sampler fills with soil and promotes from soil, the bulldozing rod top is carried, rubber cushion is clipped between soil-shifting dish and the inner core top cover tightly and inner core top cover aperture is sealed, like this in case soil tenesmus, its upper end forms vacuum immediately and soil sample is held and stops it to continue tenesmus.

The utility model compared with prior art its advantage is: 1. because rotary handle and level are held up the effect of bar and mill teeth, very laborsaving when creeping into soil layer; 2. boring is integratedly once crept into dark 10 centimetres down with sampling, promptly extracts one of soil sample, one meter of the degree of depth that fetches earth, following brill 10 times, but 10 of soil samplings, required time meter 25-30 minute; 3. the original state structure that can keep soil sample; 4. soil sample is difficult for falling when promoting soil sampler; 5. mill teeth is through Carburization Treatment, the intensity height, and wear-resistant, the scope of application is wider, and except that loose dry sand soil, other all kinds of soil comprise that the soil that contains a small amount of gravel and a small amount of thin tree root all can use.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.

Fig. 1 mills formula soil sampler structural representation for manpower revolves.

Fig. 2 mills the enlarged drawing of soil sampler in the formula soil sampler (6) for manpower revolves.

Below in conjunction with Fig. 1,2 describe concrete structure and the working condition that the utility model proposes in detail.

Vertical rod among the figure (5) is a tubulose, at the top of vertical rod (5) dress handle (2), fixed cover (3) and level are held up bar (4), fixed cover (3) is used for limit levels and holds up bar (4), level holds up bar (4) and vertical rod (5) to adopt pressure bearing (8) to be connected, when vertical rod (5) was rotated, level held up bar (4) not rotate; Dress bulldozing rod (1) in the vertical rod (5); Soil sampler (6) is installed in the lower end of vertical rod (5), the high 110MM of soil sampler (6), external diameter 60MM, there are 8 mill teeths (7) soil sampler (6) lower end, mill teeth (7) is through Carburization Treatment, tooth pitch 20MM, tooth depth 15MM, facewidth 10MM is the 15-16 degree with respect to the cutting angle of side vertical plane and vertical frontal plane.Soil sampler (6) adopts two sleeves, be inner core (13) and urceolus (10), mill teeth (7) is arranged on the urceolus (10), inner core (13) is a soil-containing tube, internal diameter 50MM, high 80MM, inside drum cover and inner core (13) are one, inside drum cover is connected with pressure bearing (8) with outer cover (9), inner core does not change, and urceolus changes, and bulldozing rod (1) passes the inside drum cover central small hole and leads in the vertical rod (5), soil-shifting dish (12) places in the inner core (13), and a rubber cushion (11) is arranged between soil-shifting dish (12) and the inside drum cover.

When the utility model is implemented, voltage levels was held up bar under rotary handle reached, and soil sampler rotates and pressurized thereupon, meanwhile, the lower end mill teeth just cuts with plane the soil that reaches two between cog under the crown and mills, promptly clamp-on among the hole wall in the outside that its " soil bits " are pressed against soil sampler, mills good circular earth pillar and enter in the tube, so soil sampler enters soil layer with regard to one side rotation one side vertical subsidence, earth pillar increases thereupon in the tube, to tube, fill till the soil, propose soil sampler then and take out soil sample, repeat above-mentioned work again.The utility model maximum degree of depth that fetches earth is 1M, and institute's soil sampling is of a size of diameter 50MM, high 50MM.
