Specific embodiment:
As shown in Fig. 1 a, 1b, the device ground swivel nut part includes bolt 1, swivel nut framework 2;
As shown in Fig. 2 device punching facilities section includes cutting bit 3, cored steel screwed pipe 4, rotates handle 5;
As shown in figure 3, the cutting bit 3 is the annulus with serrated irregular end 6, the cutting bit upper limb 7 is with Empty steel screwed pipe lower edge 8 (shown in Fig. 2) threaded connection.During herborization root system sample, rotating cutting type is taken to be completely cured, Er Feichuan The vertical method of being completely cured of system, to reduce the mechanical damage to soil.
As shown in figure 4, the cored steel screwed pipe 4 has more piece, often saving cored steel screwed pipe upper and lower side has screw thread setting, uses When be connected through a screw thread, with increase punching facility length.Its structure is the screw bushing structure of thin wall hollow, in hollow tube 9 can water filling, Outer surface of tube body is uniformly laid and is set to bladed screw thread on the outside of apopore 10, body, can connect swivel nut framework internal thread.
As shown in figure 5, the rotation handle 5 is dismountable hollow annular structure, middle part is provided with water injection hole 11, and hollow Steel screwed pipe can carry out water flood operations after connecting.Handle 12 is used to operate whole punching facility.
The accessory includes sampler protection cap, sample box, stainless steel substrates etc..
In above-described embodiment:
Cutting bit 3 is made of high-strength stainless steel material, and the serrated irregular shape end 6 that cutting bit 5 has is with suitable The Root Characters of psammophytes are answered, sand ground efficiently can be quickly pierced and cut off psammophytes root system;
Cored steel screwed pipe 4 is made of high-strength stainless steel material, and often saving cored steel screwed pipe upper and lower side has screw thread to set Put, be connected through a screw thread when using, convenient disassembly.During herborization root system sample, cored steel is used according to root length selection The quantity of screwed pipe.If need not be layered and take root, you can the sandy soil in screwed pipe are integrally released with root system, sample box is put into;If needing It is layered and takes root, usable stainless steel substrates, which are stretched into, cuts off sandy soil and root system in screwed pipe gap.During actual acquisition root system of plant sample, It can choose whether that interior water filling is managed in progress according to sand ground sandy soil dry and wet degree, the degree of packing.If sand water content is higher or compared with consolidation, Then without water filling, root is directly taken;If sand water content is low or the degree of packing is poor, easily collapsed during herborization root system sample, Now can by rotating the water filling of water injection hole 11 on handle, water will by being oozed out behind cored steel screwed pipe inside from apopore 10, To infiltrate surrounding soil, to reach fixing soil, the purpose collapsed is prevented.
In concrete application, sand ground takes the root course of work to be:
First, determine to take according to research purpose and take root in thing, take root depth, take root place, progress takes root operation.According to taking root Depth, the pattern length of determining device;According to sandy soil dry and wet degree and the degree of packing, it is determined whether carry out water filling.First will be on the ground Swivel nut is fixed on earth's surface, and swivel nut framework is is positioned over earth's surface correct position by specific operation process, and screwing bolts can be regularly Upper swivel nut.Then according to root depth assembling punching facility is taken, facility will be punched with helical rotation side from ground swivel nut internal whorl Formula is promoted in sand ground.If sandy soil are wetter, directly combine the unit, hand-held handle, root depth is taken needed for device is screwed in, without note Water;20cm is often excavated, device taking-up is outwelled and takes unwanted sandy soil and root system in the part of root, so as to being smoothed out for sampling. If sandy soil are dried, water content is low, after depth needed for device is screwed in, pours into current at the water injection hole by rotating handle, by The effect of water pressure and gravity, water can be flowed out by cored steel screwed pipe apopore, soak sandy soil around so that sandy soil structure adds By force, it should not collapse;20cm is often excavated, equally also device taking-up is outwelled and takes unwanted sandy soil and root system in the part of root.Take After depth root system needed for going out, it accessory stainless steel substrates can be used to cut off the root system between cored steel screwed pipe spiral, separate it, can divide Sample needed for depth is taken out.Sampling needs to backfill sandy soil after finishing, and treads processing.
The utility model embodiment device has the advantages that:
1. simple structure, easy to make;2. it is easy to carry, the equal decomposable asymmetric choice net of each part of the device can be transported easily It is easy to carry to work scientific research area, using flexible;3. cheap, the raw material that the device is used are that in the market is easy It is cheap in obtained common materials;4. sandy soil are held, it is to avoid the sandy soil that traditional method for digging is caused collapse problem;5. Face strength of turbulence is small, reduces potential wind erosion;6. it is laborsaving, using threaded-insert type structure, taken when using in helical rotation mode Root, works laborsaving 7. reasonable in design, can be taken off the original-pack sandy soil and root system of plant of any depth, increase work and scientific research it is accurate Property, change extensive to be intensive.
It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model is disclosed Change or replacement, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should It is defined by the protection domain of claims.
