The invention provides a soil constant-volume sampling device comprising a cylinder body in which a cavity is arranged. The soil constant-volume sampling device is characterized in that a piston push rod provided with a piston plate at the bottom and a handle at the top is arranged in the cavity of the cylinder body; the lower part of the cylinder body is movably connected with a drill provided with saw teeth at the end part; a vertical groove extending to the wall of the drill is arranged on the wall of the cylinder body; a fixed bolt is arranged in the vertical groove; a constant-volume bayonet is arranged at the lower end of the cylinder body; and a constant-volume chuck is arranged in the constant-volume bayonet along the section of the cylinder body. A sampling cylinder can be conveniently pressed into soil, and an obstruction can be cut off and smashed through the drill at the lower end of the cylinder body; soil samples are filled in the cavity of the cylinder body while the sampling depth is reached; after being taken out, the soil samples can be pushed out of the cylinder through the piston push rod; and constant-volume soil with different depths can be intercepted through the constant-volume chuck in the constant-volume bayonet without damaging the soil samples. The soil constant-volume sampling device has the characteristics of simple structure, accurate sampling volume, little damage to a sample area and the like, and is convenient to operate.
Description
Technical field
The present invention relates to a kind of sampler, particularly a kind of soil constant volume samapling device belongs to the sample collecting apparatus technical field.
Background technology
In physicism, need carry out sample collection to materials such as soil, atmosphere, water, then sample is moved to the lab analysis chemical examination.Big G﹠W all belongs to than the material that is easier to gather, and only needs simple utensil just can gather.For soil, how complete collection pedotheque always is the quite work of difficulty.Prior art adopts intubate to gather soil mostly, because soil physical is special, add that cannula structures is unreasonable, therefore gather and be difficult to intubate often because soil is really up to the mark, even if behind the insertion soil, can cause the degree of depth not enough, and can't obtain effective sample because of the stopping of the stone in the soil or plant roots and stems again.In addition, gather soil sample after finishing when taking out, again can be because of the water cut difference of soil and the soft or hard degree difference of soil property, and cause sample damage or take a sample imperfect.Must measure its soil weight when gathering the soil profile sample, existing sampling thief is constant volume samapling accurately.Therefore be necessary prior art is improved.
Summary of the invention
For solving existing soil collecting device because unreasonable structure, be difficult to intubate when causing soil to be gathered, be difficult to arrive and estimate the degree of depth soil of gathering to be caused damage or imperfect easily, accurately problem such as constant volume samapling the invention provides a kind of soil constant volume samapling device.
The present invention finishes by following technical proposal: a kind of soil constant volume samapling device, establish the cylindrical shell of cavity in comprising, it is characterized in that being provided with in the cylindrical shell cavity its bottom band piston plate, the piston push rod of top band handle, the cylindrical shell bottom is connected with the drill bit of its end band saw tooth, and barrel wall is provided with the vertical slots that extends to the drill bit wall, is provided with Fixed latches in the vertical slots, the cylindrical shell lower end is provided with the constant volume bayonet socket, is provided with the constant volume chuck along the cylindrical shell cross section in the constant volume bayonet socket.
Fixedly there is connector described cylindrical shell upper end, screw thread on the piston push rod of the screw thread of connector by its inwall and band scale flexibly connects, so that piston push rod is along screw thread upper and lower movement in cylindrical shell of connector inwall, finishing sampling, or drive piston plate the accurate constant volume of the soil sample of gathering in the cylindrical shell is released.
Connector on the described cylindrical shell and be arranged with in-line on it or the sleeve of the depression bar of X-shaped or Y shape flexibly connects is connected with setting nut simultaneously, in order to by depression bar cylindrical shell and interior piston push rod thereof together are pressed in the soil above sleeve.
The flexible connection of described connector and sleeve and setting nut is for being threaded.
Described constant volume bayonet socket is horizontally disposed with along the cylindrical shell wall, and is positioned at the below of vertical slots, and is provided with vertical outlet below this constant volume bayonet socket, move down through this mouthful to make things convenient for the constant volume chuck, thus the soil of taking-up different section.
The shape of described constant volume chuck and cylindrical shell cross sectional shape adapt, constant volume chuck one side is connected on the gripper chuck by staple, by gripper chuck the constant volume chuck is pressed in the cylindrical shell along the constant volume bayonet socket, again by rotation, the outlet that makes staple place constant volume bayonet socket below, thus the pedotheque constant volume of cylindrical shell endpiece is taken out.
Described constant volume chuck one side is connected with driving lever by staple, in order to rotate the vertical outlet that the constant volume chuck makes driving lever place constant volume bayonet socket below by driving lever, thereby the pedotheque constant volume of cylindrical shell endpiece is taken out.
The sawtooth of described drill bit lower end is provided with the reverse cutting edge sawtooth of biserial, so that after cylindrical shell is pressed into soil, by rotary barrel, the cutting action of utilizing the reverse cutting edge sawtooth of biserial to produce is cut off the stone in the soil and plant roots and stems.
Described cylinder body outer wall and Fixed latches are provided with scale mark, in order to by scale mark cylindrical shell insertion depth and sampling depth are positioned.
Described piston push rod is provided with scale mark, in order to by scale mark the pedotheque volume of gathering in the cylindrical shell is carried out accurate constant volume.
The present invention has following advantage and effect: adopt such scheme, can be when soil sampling be worked, only need one or two people just sampling cylinder can be pressed into the soil body, when running into hampers such as stone or rhizome, drive the drill bit rotation of its lower end by rotating cylinder, can be with the hamper cutting and grinding, when arriving sampling depth, also just press in the cylindrical shell cavity and expired the soil-like of gathering, behind the taking-up cylindrical shell, handle by rotary-piston push rod top, just pedotheque can be released from tube, and by the constant volume chuck in the constant volume bayonet socket, the constant volume soil of intercepting different depth, can not cause damage to pedotheque, guarantee the integrality of sample, the present invention is simple in structure, and is easy to operate, sample volume is accurate, destroys minimum to sample ground.Be a desirable pedotheque constant volume harvester in fact.
