Abstract

The utility model relates to the technical field of soil sample collecting, and discloses a sampler for soil or a plant root system. The sampler is composed of a worm gear mechanism, a worm, and a sampling drilling bit, wherein the worm gear mechanism is arranged at the top end of the worm; a swinging handle is connected with one side of the worm gear mechanism; the bottom of the worm is movably connected with the sampling drilling bit; a flange is arranged on the worm; a fixing support frame is mounted on the bottom surface of the flange; the handle can swing to drive the worm gear mechanism to rotate; the worm performs axial movement under the action of the flange, so as to drive the sampling drilling bit to enter the soil to collect a soil sample or a root sample. According to the utility model, the worm gear structure is adopted to utilize the high ratio of transmission, so that the labor intensity of operation personnel is reduced, and the work efficiency is increased; the influence on the soil sample after the sampling drilling bit enters the soil is small, and the acquired soil sample is the original soil, so that scientific analysis on the soil sample is facilitated; sampling drilling bits of different specifications can be adopted to collect the soil sample or the plant root sample for different experiment purposes.

Description

Soil or root system of plant sampler

Technical field

The utility model relates to soil sample collection machinery technical field, and one can be suitable for field work specifically, portable, labour-saving soil or root system of plant sampler.

Background technology

Pedology research is the very important science of subject such as agricultural, grass cultivation, forestry, environmental protection.By soil investigation, contribute to researcher to understand nutritional labeling and the physicochemical property of testing soil, and then take corresponding technical measures or control measures, recover soil health or reflect certain some problem in science.

Soil sample collector, claims again earth boring auger, is to be widely used at present a kind of instrument that gathers soil sample.This class instrument can carry out the mensuration of soil physico-chemical property, rescarch of underground biomass etc., having reduced traditional digging tool results soil block wastes time and energy, the restriction of spoiled soil and vegetation and sampling multiplicity, excavating soil block harvest method with original tool compares, having the advantages such as sampling is rapid, easy, easy, area coverage is large, is the better method of research agricultural and Grassland ecosystems radicula underground biomass.The multiplex T-shaped structure of soil sample collector at present, this sampler is furnished with drill bit in the bottom of thief rod, and top is provided with handle, and power resources are divided two classes, i.e. manpower or machine power.There is shortcoming in T-shaped soil sample collector:

(1) waste time and energy: use the T-shaped soil sample collector of manual operation, in the time that quantity of sampling quantity is larger, waste time and energy.In Qinghai-Tibet alpine meadow area, grassland soil densification, sampling work is more difficult.Because sampling relies on the handle that constantly turns T-shaped soil sample collector, need larger arm strength.If with the soil layer sampling every 10cm, get 3 layers, be sampled to 30 centimetres, a between twenty and fifty labour of the male sex can only sample 50 left and right every day, works powerful.

(2) machine power is not suitable for field work: use machine power, as petrol engine, the such device weight of producing at present is both at home and abroad generally in 20KG left and right, not portable when field work.Although electric power is lighter, when field work, in the area such as grassland, forest farm, there is no power source especially, therefore, the few people of field soil sampling at present use.

(3) the non-undisturbed soil of pedotheque obtaining.T-shaped soil sample collector just can creep into soil owing to turning with strength downwards in the time of sampling, generally causes the compacted compacting of pedotheque, and therefore, in the pedotheque of taking-up, original soil texture is destroyed, can not accurately reflect undisturbed soil character.

(4) drill bit is single.Most of T-shaped earth boring auger, can only use a kind of drill bit.And be only suitable for collecting soil sample, as want herborization subterraneous root sample, bit change more.Need to complete the different sampling task such as soil or root system of plant time, need to carry the soil sample collector of Multiple Type drill bit.

Utility model content

The purpose of this utility model is to provide a kind of soil or root system of plant sampler, the problem such as bit change more when solving the compacted compacting of pedotheque that traditional soil sample collector is wasted time and energy, inconvenient field is carried, obtained, different sampling task.

For solving the problems of the technologies described above, technical solution adopted in the utility model is:

A kind of soil or root system of plant sampler, it is made up of worm-and-wheel gear, leading screw, chisel bit, and described worm-and-wheel gear is arranged on the top of described leading screw, and the bottom of described leading screw is flexibly connected with described chisel bit.

As further improvement of the utility model, described leading screw is provided with flange, and the bottom surface of described flange is provided with fixing support rack.

Further improve as of the present utility model, a side of described worm-and-wheel gear is connected with swinging handle.

Further improve as of the present utility model, a side of described worm-and-wheel gear is connected with motor.

In the utility model, drive worm-and-wheel gear to rotate by swinging handle or motor, leading screw is moved downward, and axially-movable under the effect of flange, drive chisel bit to enter and in soil, take soil sample or plant roots sample.Leading screw adopts and is flexibly connected with chisel bit, can, according to different job requirements, change different drill bits; Fixing support rack is inserted in soil, for the utility model provides support, prevents leading screw oppositely lifting under the effect of reacting force in going down process.The beneficial effects of the utility model are:

(1) time saving and energy saving: owing to having adopted worm gear structure, utilize the principle of its big speed ratio, can manual operation swinging handle or adopt motor to drive worm-and-wheel gear motion, greatly reduce operating personnel's labour intensity, improve work efficiency;

(2) undisturbed soil sample: due to labour-saving project organization, the minimum that affects on extraction soil sample after chisel bit enters soil, is conducive to analyse scientifically pedotheque;

(3) interchangeable bit: according to test objective difference, the drill bit of replaceable different model is in order to gather soil sample or root sample.
