Description

Plant root system sampler
Technical field
This utility model relates to a kind of sampling apparatus, is specifically related to a kind of plant root system sampler.
Background technology
Root system plays vital effect for the growth promoter of plant, people had begun to the research to root system before very early, German scholar Hales have employed simple mining method and describes different plant variety root system distribution in soil in 1727, be first document record root system is compared systematic research, more than 100 year later, people continue to use this method to study root system always.
In China, in the chronic study procedure of crop root, due to the impact of the factor such as cognitive ability of the feature of the age, culture scientific and technological level and people, different before and after its research range, content, emphasis and effect etc..In recent decades, growing and the truth of distribution to grasp root system of plant in soil, people investigated the observation procedure of multiple root system.Existing root system research method generally falls into sampling and measurement two steps carry out.The root system that requirement obtains is complete, and referring at least to the main root system of research purpose can not be incomplete, and its original state in soil environment also should be kept indeformable, and sampling work requires quickly and accurately.
Wherein, bore a kind of method that core method is conventional root system of plant sampling, boring core method is that the method utilizing manpower or machinery gathers soil sample from field, thus reaching the mensuration to rescarch of underground biomass, the sixties in 20th century is formally begun to use the mensuration carrying out root system of plant.The topmost instrument of this method is earth boring auger, and from several centimetres to tens centimetres not etc., root characteristic distributions, heterogeneity and the sampling specific experiment situation such as frequency and precision prescribed are depended in the selection of bit diameter to bit diameter.If distinguishing the Biomass of the root of soil different levels, then core is also kept to stand intact, it is to avoid fragmentation;As sample can not immediately treat, should by core stored frozen;When root is classified, in addition it is also necessary to hairbrush, anatomical lens, dissection tweezers etc.;The whole process of sample treatment also needs altex glove on band, to prevent the pollution to root.The determination of the frequency and the number of every sub-sampling, concrete interval of boring the sampling of core method to be determined according to the growth characteristics of studied plant roots.The number of sampling in the conceived case, should give more repetition as far as possible.By the mensuration to every sub-sampling sample, it is possible to the Biomass etc. of root is analyzed.
The core method sampling of boring is rapidly, easy, easy, area coverage is big, thereby reduces environmental heterogeneity error, and measurement result is more accurate, and the destructiveness of soil and vegetation is also relatively lighter.
But the sampling apparatus majority boring the employing of core method at present is simple rustless steel earth boring auger, worm-and-wheel gear, leading screw, chisel bit form, though its simple in construction, need manual rotation in use and be downwardly applied to pressure, even need to pound with a hammer to realize its function boring soil sampling.
A kind of automaticity is high, reduces manpower and materials, and a kind of novel sampling equipment that simultaneously can alleviate researcher work burden needs exploitation badly.
Utility model content
In order to solve the problems referred to above, this utility model provides a kind of plant root system sampler, and this sampler have employed the chisel bit of motor-driven sampler, and with infrared distance measurement device, can realize being accurately positioned sampling depth, alleviate the labor intensity of researcher, improve work efficiency.
For achieving the above object, this utility model adopts the following technical scheme that, a kind of plant root system sampler, including handle, sleeve, drilling rod, drill bit, piston, connecting rod, infrared distance sensor and motor;Described handle upper end is provided with motor installation position, and described motor installation position is provided with infrared distance sensor;Described motor is arranged on motor installation position;

Described drill bit is columnar structured, and the end of described drill bit is ramp structure, and the edge on described inclined-plane is broached-tooth design.
Further, the outer surface of described drill bit is provided with helicitic texture, and the inner surface of described drill bit is smooth structure.
Further, described motor is provided with gyroscope induction apparatus.
Further, described motor is provided with converter.
Further, described infrared distance sensor is provided with boom unit.
Further, described motor installation position is provided with LED.
Further, described motor installation position is provided with chargeable lithium cell.
A kind of plant root system sampler that this utility model provides, motor in use, is arranged on motor installation position by this device, and drill bit alignment needs the position of sampling, set the degree of depth of sampling, opening motor, motor drives drill bit to rotate by drilling rod, the unique texture of drill bit, inclined-plane, sawtooth and screw thread make the driving of drill bit more rapidly and efficiently, when drill bit gets into predeterminable range, the boom unit of infrared distance sensor starts to remind, and motor is automatically stopped work simultaneously;Now, after motor cuts out, sampler is extracted from soil, then promote piston rod the cylindrical soil root compositions of sampling to be released, namely complete once to sample;Also having gyro sensor in equipment, when sampling carries out in process, imprudence equipment skews, now gyroscope automatically detects equipment and is in abnormal operating state, making motor stall at once, to avoid drill bit that staff is damaged, safety is more secure;Equipment is additionally provided with LED, conveniently samples more easily under the environment that intensity of illumination is relatively low, and motor is provided with converter, it is possible to prevent motor apparatus overload when running into bigger resistance from burning.
The utility model has the advantage of: this sampler have employed the chisel bit of motor-driven sampler, and with infrared distance measurement device, it is possible to achieve it is accurately positioned sampling depth, alleviates the labor intensity of researcher, improve work efficiency;It is provided with safety guard, it is prevented that cause the infringement of equipment and the injured of personnel simultaneously.
