Description

A kind of Portable rotary piston sample
Technical field
The utility model relates to a kind of test drawing out soil equipment, belongs in civil engineering work that in geotechnical investigation field and Geological Engineering geological mapping field.
Background technology
Geotechnical engineering investigation field in civil engineering work, soil sample barrel is as a kind of soil body analytical sampling, and the aid of soil test sampling, is widely used in scientific research, teaching and production.Drawing out soil equipment conventional in engineering is cutting ring, but only can not meet the requirement of the aspects such as research and teaching by ring, the field of original position prospecting especially in the wild along with the progress of science and technology.So there has been the drawing out soil equipment that some are new.But fetching earth of having in the soil sample barrel applied for a patent disclosed in those is more shallow, can not deep layer fetch earth, what have limits by condition, and what have carries inconvenience, and needing of having repeatedly fetches earth.To sample undesirable, repeatable operation when conventional earth boring auger fetches earth on the spot to solve, wasting time and energy, efficiency is low, soil sample carries inconvenience, use inflexible practical problems, this patent is explored from earth boring auger syndeton and the brill soil mode of fetching earth and is applied, and obtains a kind of Portable rotary piston drawing out soil equipment.
Utility model content
The purpose of this utility model be to overcome prior art not enough and provide a kind of structure simple, easy to carry, manually rotate soil sample barrel, the soil body that compactness is higher can be cut, less to surrounding soil disturbance, fast soil sample can be taken out from device, easy to carry, be applicable to the Portable rotary piston sample of different depth.
The purpose of this utility model is achieved by the following technical programs:
A kind of Portable rotary piston sample, is characterized in that, comprise hollow outer tube and be sleeved on the piston axle in described outer tube, the length of piston axle is greater than the length of described piston outer tube.The external diameter of described piston axle and the internal diameter of described outer tube match.The head end of described piston axle is exactly piston head, and outer tube head end is equipped with the pipe that fetches earth, and the internal diameter of the pipe that fetches earth is identical with the internal diameter size of outer tube.Be provided with spiral helicine chip pocket outside the head end of described piston head and the pipe that fetches earth, described in fetch earth pipe and the front end of piston head be provided with cutting edge.Described outer tube is provided with the stop means that limited piston moves up and down.The tail end of described outer tube has a rotary handle, and the connecting link of earth boring auger handlebar and tail end outsourcing outer tube is socketed by connecting thread and steel pipe.Outer tube and piston axle by the component of several same size, each via being threaded.
Described stop means feature comprises pin and to be arranged on described outer tube and to be arranged on piston axle and match with outer tube pin-and-hole.Described piston axle is fixed by pin and outer tube.The end-position of every section of outer tube and piston axle has a spacing hole.
The tail end of piston axle has piston axle when preventing soil sample barrel from installing injure people by a crashing object from front end landing or make a mess of the piston handle of piston head.
Often the connection saved between piston axle is all be enclosed within soil end far away by screw thread nested encryptions nearly soil end, often save outer tube and between connection be all hold by screw thread and junction button nested encryptions nearly soil and far natively to hold.Cut the consistent external diameter of interface outer tube diameter consistent with junction button external diameter, piston axle external diameter is consistent, slides up and down to facilitate piston axle.
The lateral wall of every section of outer tube is equipped with scale and conveniently knows the got degree of depth.
The connecting link of tail end outsourcing outer tube can be threaded with crossing with the tail end of every section of outer tube.
The length of every section of outer tube and piston axle is all about 900 ~ 1200mm.The internal diameter of outer tube has between 35mm, 40mm to 90mm and has 12 ranks.External diameter 1 ~ the 2mm less of the internal diameter of outer tube of piston axle, slides up and down to facilitate piston axle.
Owing to adopting such scheme, the utility model makes outer tube and piston axle convenient fixing that soil sample barrel is screwed in assigned address and ideal position by stop means.The pipe that fetches earth on piston head and outer tube is combined to form drill bit, and by handle manual rotation outer tube, just can cut the higher or harder soil body of compactness, roach is discharged by chip pocket.This device can the soil pattern of the multiple different depth of disposable acquisition, and simple and convenient avoiding repeatedly is fetched earth in batches.The soil utilizing the utility model to obtain not be used in the packing that soil pattern was carried out in borrow areas at that time, only after complete for native pipe mark, need take back by marking clearly outer tube packing and the detection that soil sample sample is carried out in laboratory, decrease the existing tube edge that fetches earth to fetch earth the complicated processes of earth limit packing, can 10% ~ 20% be raised the efficiency.Utilize the scale of outer tube can know the degree of depth of fetched earth earth.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model done and illustrate further.
See accompanying drawing 1 ~ 7.The first step: first estimate the degree of depth fetched earth, install this drawing out soil equipment according to the degree of depth that fetches earth.Piston axle 5 now with piston handle 6 is connected by rotating screw thread 10 with piston axle 3, and piston axle 3 can have multiple.Again the piston axle 1 with piston head is connected with piston axle 3.
Second step: junction button is connected by rotating screw thread 12 with outer tube 4, more several outer tubes 4 is connected to the outer tube head end just connected by junction button 11, finally the outer tube 2 with the pipe 14 that fetches earth is connected to the head end of outer tube 4.
3rd step: the outer tube connected is rotated adjustment two pipe from there being one end of junction button to be enclosed within piston axle the spacing hole on two pipes is aligned, then pin is inserted the spacing hole internal fixtion of the one end near junction button.Rotary handle 15 to be connected with junction button by screw thread 13 and to tighten.Device connects complete.
Being screwed in by rotary handle by drawing out soil equipment specifies the pin then pulled out in spacing hole in soil layer to continue downward screwing device, and at this moment moving down, outer tube does not continue to move down piston axle, and watches the scale on outer tube.Can stop until being threaded to designated depth.
Disposable connection is not a lot of for piston axle 3 and outer tube 4 at the beginning, in order to avoid rotary handle overhead too high use inconvenience, can pull down piston axle 5 and junction button, then add piston axle 3 and outer tube 4, finally again loading onto of removing along with the degree of depth screwed in.
After fetching earth, drawing out soil equipment is oppositely screwed out device of dismantling.Soil sample in outer tube is retained in wherein labelled notation good seal and takes back laboratory.
Be described in detail the utility model embodiment above, apply specific case herein and set forth embodiment of the present utility model, the explanation of above embodiment just understands core concept of the present utility model for helping.Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
