Abstract
The utility model relates to soil investigation utility appliance field, discloses a kind of soil sample drill bit.It comprises drill body, be arranged on the connecting link on drill body top, the groove be arranged on drill body sidewall, and described drill body is the right cylinder of bottom end opening, and the inwall of described drill body is provided with muscle.The utility model arranges muscle on the inwall of drill body, adds resistance when sampling soil drops, and can effectively prevent sampling soil from dropping in drill bit; Being provided with of muscle helps the intensity strengthening drill body, is applicable to comparatively stiff soil sampling operation; The utility model arranges cutting edge straight down at the bottom end opening place of drill body, be conducive to the cutting of drill bit to soil descending, improves the speed fetched earth.The utility model structure is simple, is applicable to various dissimilar soil, need not carries polytype drill bit, alleviate the burden of field work personnel.
Description
Technical field
The utility model relates to soil investigation utility appliance field, can prevent a kind of soil sample drill bit that sampling soil drops specifically.
Background technology
Pedology research is the very important science of subject such as agricultural, grass cultivation, forestry, environmental protection.By soil investigation, contribute to nutritional labeling and physicochemical property that researcher understands testing soil, and then take corresponding technical measures or control measures, recover soil health or reflect certain some problem in science.
Soil sample collector, also known as earth boring auger, be widely used in a kind of instrument gathering soil sample at present, the mensuration of soil physico-chemical property, rescarch of underground biomass etc. is carried out in the use of this kind of instrument, decrease traditional digging tool results soil block to waste time and energy, the restriction of spoiled soil and vegetation and sampling multiplicity, and the native core drilling method formed thus excavates soil block harvest method than original tool, having the advantages such as sampling is rapid, easy, easy, area coverage is large, is the better method of research Grassland ecosystems radicula underground biomass.
The drill bit of current soil/root system sampler, is mainly divided into heart-shaped soil sample drill bit and tubular soil drill bit two class, adopts different soil sample collectors according to different soil typess.Heart-shaped soil sample drill bit is mainly used to get clay, loam, and tubular soil drill bit is mainly used to get loam, peat soil and sandy soil etc.Because the viscosity of sandy soil and loam is lower, easily drop out from drill bit, generally do not adopt tubular soil sample collector not easily to get sandy soil and loam; When heart-shaped soil sample collector fetches earth, the soil that water cut is low easily drops from drill bit, and heart-shaped drill bit design is unfavorable for the sampling of different soil, as sampled soil at 20CM, due to the out-of-shape of drill bit, accurately cannot carry out quantitative sampling.Therefore, many employings tubular chisel bit when current soil quantitative sampling.
In order to prevent sampling soil from dropping out from the cylindrical shell of drill bit, usually that drill margin is bending inside inner barrel, drop in drill bit to prevent sampling soil when sampler promotes after sampling; But bending drill margin adds the resistance of drill bit incision soil, have impact on work efficiency.
In the wild during operation, staff usually needs to carry different drill bits, samples, bring inconvenience to field work for different soil.
Utility model content
The purpose of this utility model is to provide a kind of soil sample drill bit, to solve the problem that when existing soil sample collector promotes after sampling, sampling soil easily drops in drill bit.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of soil sample drill bit, it comprises drill body, is arranged on the connecting link on drill body top, the groove be arranged on drill body sidewall, and described drill body is the right cylinder of bottom end opening, and the inwall of described drill body is provided with muscle.
As further improvement of the utility model, described muscle is spiral helicine bonding jumper.
Further improve as of the present utility model, described drill body bottom end opening place is provided with cutting edge straight down.
The utility model arranges muscle on the inwall of drill body, adds resistance when soil drops in drill bit, can effectively prevent sampling soil from dropping in drill bit; Being provided with of muscle helps the intensity strengthening drill body, is applicable to comparatively stiff soil sampling operation; The utility model arranges cutting edge straight down at the bottom end opening place of drill body, be conducive to the cutting of drill bit to soil descending, improves the speed fetched earth.The utility model structure is simple, is applicable to various dissimilar soil, need not carries polytype drill bit, alleviate the burden of field work personnel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, drill body, 2, connecting link, 3, groove, 4, cutting edge, 5, muscle.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of soil sample drill bit as shown in Figure 1, it comprises drill body 1, be arranged on the connecting link 2 on drill body 1 top, the groove 3 be arranged on drill body 1 sidewall, drill body 1 is the right cylinder of bottom end opening, the inwall of drill body 1 is provided with spiral helicine muscle 5, and drill body 1 bottom end opening place is provided with cutting edge 4 straight down.
The material of muscle 5 is metal.
Fetch earth in the wild operation time, the utility model is arranged on drilling rod by connecting link 2, apply to rotate downward acting force to drill body 1, cutting edge 4 is cut in soil, by job requirements to after soil sample, promote drill body 1, sampling soil promotes together in company with drill body 1, leaves original soil layer, and sampling soil drops downwards under gravity, muscle 5 decomposes the gravity straight down that sampling soil bears, and then prevents sampling soil to drop in drill body 1; The soil sample sample taken out, under the effect of groove 3, can take out easily in drill body 1.
The utility model structure is simple, easy to carry, is applicable to various dissimilar soil property and quantitative sampling operation, sample rate block.
