Abstract
The utility model relates to the fields of environmental research and agricultural research, and discloses a soil sampling device. The soil sampling device comprises a handle and a hollow drill drum which are vertically and fixedly connected with each other; the soil sampling device is characterized in that the hollow drill drum is divided into a drill drum body and a semi-circular-ring drum body which is matched with the drill drum body; a sleeve for fixing the drill drum body and the semi-circular-ring drum body with each other is sleeved on the outer wall of the hollow drill drum; and a fixing bolt which is fastened with the hollow drill drum is arranged on the sleeve. As a sampling tank design is avoided, the soil sample is free from pollution, and the sampling test can be relatively accurate; and the soil sampling device is simple in structure and convenient for sampling; and by adopting the sampling device, the sampling efficiency is greatly improved.
Description
Technical field
The utility model relates to Environmental Studies and agricultural research field, particularly a kind of pedotheque harvester.
Background technology
The collection of pedotheque exists ubiquity concerning environment and agricultural research.And earth boring auger is especially used during the section pedotheque very extensive as a kind of sampling instrument gathering pedotheque.At present, traditional earth boring auger is formed by boring tube and handle two parts, and boring a tube partial design has sampling groove, when sampling, is applied acting force downward or upward to earth boring auger and earth boring auger is entered or withdraws from soil and finish sampling by operating personnel.But traditional earth boring auger has following shortcoming: at first, and in the earth boring auger sampling process, because of with the friction force of soil, the soil sample of different soil is mixed, thereby causes sample contamination, especially when measuring soil trace element, bigger to the sampling precision influence; Secondly, the sampling groove limited length of tradition earth boring auger mostly is 40cm, therefore at sampling depth when boring the pedotheque of tube length degree, just need the repeated multiple times operation just can finish the soil sample collection, so not only strengthen sample collector's labour intensity, reduced sampling efficiency, and, because soil falls into boring easily near the boring after earth boring auger is taken out soil layer, these soil can be gathered together in next bores in company with deep soil, mix, thereby have influenced sampling precision.
Summary of the invention
The purpose of this utility model is to provide a kind of pedotheque harvester, avoids the sampling groove design, makes pedotheque not contaminated, makes the sampling test more accurate, and it is simple in structure, and sampling is convenient, improves sampling efficiency greatly.
For achieving the above object, the utility model is achieved by the following technical solutions.
A kind of pedotheque harvester, comprise handle and core drill tube, described handle is vertical affixed with the core drill tube, it is characterized in that, described core drill tube is divided into the semicircular ring cylindrical shell that bores the tube body and cooperate with brill tube body, be set with the sleeve that described brill tube body and semicircular ring cylindrical shell are interfixed on the outer wall of described core drill tube, described sleeve is provided with the set bolt fastening with described core drill tube.
Characteristics of the present utility model and further the improvement are:
Described brill tube body and semicircular ring cylindrical shell are respectively equipped with groove and projection radially, wherein, and the groove on the brill tube body and the projection corresponding matching on the semicircular ring cylindrical shell, the projection on the brill body and the groove corresponding matching on the semicircular ring cylindrical shell.The characteristics of the technical program and further the improvement are:
Described groove and projection are regular length, and indicate as scale mark with the groove on the described brill tube body and the adjacent lines of projection.
Pedotheque harvester of the present utility model, the core drill tube is divided into the semicircular ring cylindrical shell that bores the tube body and cooperate with brill tube body, be set with the sleeve that described brill tube body and semicircular ring cylindrical shell are interfixed on the outer wall of described core drill tube, described sleeve is provided with and the described fastening set bolt of tube body that bores; After the pedotheque collection is finished, unscrew set bolt, lay down sleeve and semicircular ring cylindrical shell, contrast is bored scale on the tube body to the soil test of sampling, and can make soil not contaminated, the raising testing precision, it is simple in structure, and sampling is convenient, improves sampling efficiency greatly.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the one-piece construction synoptic diagram of pedotheque harvester of the present utility model.
Fig. 2 is the handle of the pedotheque harvester asked among Fig. 1 and the structural representation of core drill tube.
Among the figure: 1, handle; 2, bore the tube body; 3, semicircular ring cylindrical shell; 4, sleeve; 5, set bolt.
Embodiment
With reference to Fig. 1, be the one-piece construction synoptic diagram of pedotheque harvester of the present utility model.This pedotheque harvester comprises handle 1 and core drill tube, handle 1 is vertical affixed with the core drill tube, the core drill tube is divided into the semicircular ring cylindrical shell 3 that bores tube body 2 and cooperate with brill tube body 2, bore and be set with the sleeve 4 that brill tube body 2 and semicircular ring cylindrical shell 3 are interfixed on the outer wall of body 2 core drill tubes, sleeve 4 is provided with the set bolt 5 fastening with the core drill tube.
With reference to Fig. 2, be the handle of the pedotheque harvester asked among Fig. 1 and the structural representation of core drill tube.Brill tube body 2 and semicircular ring cylindrical shell 3 are respectively equipped with groove and projection radially, wherein, and the groove on the brill tube body 2 and the projection corresponding matching on the semicircular ring cylindrical shell 3, the projection on the brill body 2 and the groove corresponding matching on the semicircular ring cylindrical shell 3; Groove and projection are regular length, and every section is 20cm, and indicates as scale mark with this length, when making soil sampling, can know the degree of depth of seeing the soil of surveying intuitively; In addition, brill tube length degree adds to grow to can gather the dark soil profile soil sample of 0-100cm, saves the sampling time, has improved sampling efficiency.
Pedotheque harvester of the present utility model, during use, to bore tube body 2 earlier and cooperatively interact into the core drill tube with semicircular ring cylindrical shell 3, again sleeve 4 is inserted in the outside of core drilling, and it is with set bolt 5 that sleeve 4 is fastening, make brill tube body 2 and semicircular ring cylindrical shell 3 fit in a complete core drill tube, carry out soil sampling; After the pedotheque collection is finished, unscrew set bolt 5, lay down sleeve 4 and semicircular ring cylindrical shell 3, contrast is bored scale on the tube body 2 to the soil test of sampling, and can make soil not contaminated, the raising testing precision, it is simple in structure, and sampling is convenient, improves sampling efficiency greatly.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, the utility model is not limited to above-mentioned specific embodiments, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protects, can also make a variety of forms under the enlightenment of this instructions, these all belong to the row of the utility model protection.
