Abstract
The invention relates to a piston type soil sampler which comprises a handle (1), a support rod (2), a thrust ring (3), a connecting rod (4), a piston (5), a sampling tube (6) and a fixed pin (7). The piston type soil sampler is characterized in that the upper end of the support rod (2) is connected with the handle (1) in a threaded manner while the lower end of the same is connected with the upper end of the sampling tube (6) in a threaded manner, the sampling tube (6) is a hollow steel tube; from the 2.5cm position to the 50cm position above the bottom of the sampling tube (6), a steel tube wall surface area of 2/5 of the sampling tube (6) is opened; the piston (5) is mounted in the sampling tube (6) via the opening position of the sampling tube (6), and the thrust ring (3) is sleeved outside the sampling tube (6) and connected with the piston (5) via the connecting rod (4). By utilizing the thrust ring (3) to push the piston (5), a soil column in the sampling tube (6) can be thrust out conveniently and safely, and the piston type soil sampler is simple in structure, convenient to use and carry, economical and practical.
Description
Technical field:
The present invention relates to a kind of piston type soil sample collector, belong to proportion of crop planting cultivation technique field.
Background technology:
Field test and pedology research are common methods of agriculture as the foundation of the economy and applied research.In field test, in order to grasp soil characteristic experimental field, need to carry out soil sample.Namely use special-purpose soil sample collector, take out pedotheque in predetermined place punching."T"-shaped soil sample collector is soil sample collector commonly used at present, its upper end is two handles, the middle handle stopple coupon that the below ins succession and takes a sample, middle handle is made of hollow steel pipe, bottom 2cm is closed, the steel pipe walls of its bottom and 2cm upper limb all is acute angle shape, and the above steel pipe walls to 50cm of 2cm has 2/5 to be opening.During sampling, the operator uses the handle vertical depression, rotates simultaneously, and under the incision of the steel pipe walls of bottom acute angle, the soil of sampling spot is pressed in the steel pipe of hollow.The operator will carry in the sampler rotation, and the soil sample in the sampler steel pipe is taken out of sampling spot along with the rising of sampler; The operator tilts sampler, raps to beat, and is aided with hand, makes the opening part of the above soil sample of sampler bottom 2cm from 2/5 shift out the sampler steel pipe.But, in the soil at the closed stopple coupon place of bottom 2cm still is retained in stopple coupon, need to it could be taken out with other supplementary meanss.Because the two ends of the steel pipe exposed section at 2cm place, stopple coupon bottom are acute angle, add that the pressure that soil herein bears is maximum, soil sample is the most solid, therefore be difficult to take out, the operator is careless slightly will come to harm, and brings a lot of inconvenience to real work.
Summary of the invention:
The object of the present invention is to provide a kind of piston type soil sample collector, can easily and safely the earth pillar in stopple coupon all be released, have simple in structurely, easy to use, be easy to carry, economical and practical characteristics.
The present invention realizes above-mentioned purpose by following technical solution.
In a kind of structure of piston type soil sample collector, be provided with handle, support bar, thrust ring, connecting link, piston, stopple coupon, fixed pin; Upper end and the handle of support bar are threaded connection, and the upper end of lower end and stopple coupon is threaded connection; Stopple coupon is the steel pipe of hollow, and from the bottom 2.5cm up of stopple coupon to the 50cm place, it is opening that stopple coupon has 2/5 steel pipe walls area; The diameter of piston is identical with the internal diameter of stopple coupon; Piston is arranged in stopple coupon by the opening part of stopple coupon; Thrust ring is sleeved on outside stopple coupon; Thrust ring is connected by connecting link with piston; Lower end at stopple coupon is equipped with fixed pin.
The present invention has following beneficial effect compared with prior art:
1, the present invention by the thrust ring pushing piston, can all release the earth pillar in stopple coupon, and soil sample is released thoroughly clean, and high efficiency is particularly suitable for the higher soil of water cut.
2, safety simple to operate has been avoided going mobile soil sample with other supplementary meanss, has improved the safety coefficient of sampling operation.
3, simple in structure, easy to use, be easy to carry, economical and practical.
Description of drawings:
Fig. 1 is general structure schematic diagram of the present invention.
Fig. 2 is the structural representation of thrust ring of the present invention and piston portion.
In figure: 1. handle, 2. support bar, 3. thrust ring, 4. connecting link, 5. piston, 6. stopple coupon, 7. fixed pin.
Embodiment:
A kind of piston type soil sample collector of the present invention is comprised of handle 1, support bar 2, thrust ring 3, connecting link 4, piston 5, stopple coupon 6, fixed pin 7; The upper end of support bar 2 and handle 1 are threaded connection, and the upper end of lower end and stopple coupon 6 is threaded connection; Stopple coupon 6 is the steel pipe of hollow, and from the bottom 2.5cm up of stopple coupon 6 to the 50cm place, it is opening that stopple coupon 6 has 2/5 steel pipe walls area; The diameter of piston 5 is identical with the internal diameter of stopple coupon 6; Piston 5 is arranged in stopple coupon 6 by the opening part of stopple coupon 6; Thrust ring 3 is sleeved on outside stopple coupon 6; Thrust ring 3 is connected by connecting link 4 with piston 5; Thrust ring 3 and piston 5 can move up and down on stopple coupon 6; In the lower end of stopple coupon 6, fixed pin 7 is installed, can prevents that thrust ring 3 and piston 5 from skidding off from the lower end of stopple coupon 6.
When using the present invention to carry out soil sample, the thrust ring 3 in soil sample collector and piston 5 are placed in the top of stopple coupon 6; With the sample tap aligning sampling spot of soil sample collector lower end, stopple coupon 6 must be perpendicular to the ground; The operator is the downward application of force in turning handle 1, and stopple coupon 6 is inserted in soil vertically downward, progressively enters sampling soil, stops after reaching predetermined sampling depth of soil; When taking out pedotheque, operator's turning handle 1 is upwards had an effect simultaneously, progressively soil sample collector is extracted out the soil sample layer; Then promote thrust ring 3 and piston 5 downwards, pedotheque is released from stopple coupon 6.
