Description
Technical field
The present invention relates to civil engineering sampling instrument field, particularly relate to one and to fetch earth cutting ring device.
Background technology
Cutting ring is a kind of testing equipment for soil test, is mainly used to produce soil sample, for measuring the test such as density, water cut of soil.Cutting ring is in fact the column type sleeve of a rigidity, both ends open, and wherein one end is with sharper cutting edge.When specifically using, first prepare larger soil body sample, be then placed on soil sample by cutting ring, cutting edge contacts with specimen surface, then firmly to pressing down, makes cutting ring enter soil sample.In the process moved downward firmly making tool changing, in the soil sample of the blade incision periphery of cutting ring, after cutting ring enters completely and penetrates soil sample layer, the soil sample in cutting ring being taken out and has just made complete soil sample.In traditional experiment, be directly press mode by hand cutting ring is compressed into soil sample downwards, if but run into the hard sample of soil property, then to be by hand difficult in cutting ring pressing in sample.Therefore, must improve cutting ring, can be pressed into easily in certain degree of hardness sample.
Summary of the invention
Conveniently materials in hard soil property, the present invention proposes a kind of lever to fetch earth cutting ring device, cutting ring is pressed in the soil body by the strength by lever, the present invention improves existing cutting ring, increase a separable leverage fetching earth on cutting ring, this leverage comprises flexible handle, and the support column that be fixedly connected with vertical with base, flexible handle is positioned at support column top and is flexibly connected by bolt with support column, and flexible handle up and down reciprocatingly can pass through screws; The interposition of flexible handle is equipped with the sleeve pipe that can slide along fixed handle, and on sleeve pipe, movable bolt connects force application rod, and force application rod and pressure plate are bolted to connection, and are cutting ring below pressure plate; When soil sampling, soil sample is placed on the base of cutting ring device, again cutting ring blade to being placed down in above soil sample, being pulled upwardly handle again makes pressure plate just be placed on above cutting ring, slidable adjustment sleeve pipe again, makes force application rod vertically sagging, firmly pulls down fixed handle, allow pressure plate evenly exert pressure to cutting ring, cutting ring is entered in soil sample.Fluted in the plane of pressure plate here and cutting ring contact position, when pressure plate is exerted pressure to cutting ring, the afterbody of cutting ring just can enter in this groove, prevents pressure plate and cutting ring relative sliding in course of exerting pressure.
Above-mentioned handle is four rib types, and correspondingly sleeve pipe is also four rib type pipes, and the inwall up and down of sleeve pipe and handle contact has roller bearing, it is rolling friction between sleeve pipe and handle, when handle continues downward, sleeve pipe is automatic rolling on handle, keeps vertical state to regulate force application rod.
The further improvement of technique scheme is, the adjustable in length of force application rod, force application rod can regulate the connection distance of force application rod and pressure plate through the hole in the middle of bolt, bolt there is buckle, force application rod can be tightened and be fixed in the hole of bolt after regulating distance, here by the length adjustment of force application rod, the operation to differing heights soil sample and cutting ring can be adapted to.
The present invention achieves following technique effect:
By the present invention, cutting ring is improved, available common manual pressure mode, smoothly cutting ring can be pressed in hard soil sample and materials.Overall sampling process uniform force application, improves efficiency and the quality of sampling.
Accompanying drawing explanation
Fig. 1 is that lever of the present invention fetches earth cutting ring device schematic diagram.
Embodiment
Understand for the ease of those of ordinary skill in the art and implement the present invention, below in conjunction with the drawings and the specific embodiments, the present invention is described in further detail.
See Fig. 1, the present invention mainly installs a lever device for exerting additional on traditional cutting ring that fetches earth, and utilizes the laborsaving principle of lever, greatly increases the pressure on cutting ring, cutting ring successfully can be pressed in hard soil sample and obtain sample.
Embodiment 1:
Design a lever of the present invention to fetch earth cutting ring device, see Fig. 1, design the sampling bench that can be installed leverage, sampling bench comprises: diameter is the round metal bench-type base 13 of 100mm, thick 10mm, it is highly the column type support column 12 of 100mm that a diameter 20mm is vertically fixed at base 13 edge, support column 12 upper end connects a flexible handle 8, this flexible handle 8 is exactly the critical piece that the present invention serves as lever, flexible handle 8 is connected by movable bolt 11 with support column 12, and flexible handle 8 can freely up and down rotate.The cross section of flexible handle 8 is the square of length of side 10mm, and the length of flexible handle 8 is greater than 100mm, is made up, can turns to bear larger torsion indeformable of rigidity hard four rib shaped material.
The sleeve pipe 10 that flexible handle 8 can slide, sleeve pipe 10 inwall is close to flexible handle 8 outer wall can carry out smooth slip, in order to reduce friction force, the inwall up and down of the sleeve pipe that sleeve pipe 10 contacts with handle 8 being inlaid with roller bearing, is rolling friction between sleeve pipe 10 and handle 8.
There is movable bolt 9 the horizontal side of sleeve pipe 10 for connecting force application rod 6, and force application rod 6 is the cylinder type metal bar of diameter 10mm, is fixedly connected with by bolt 7 with pressure plate 5, pressure plate 5 is pyramid type, and cone diameter is greater than 65mm, is generally greater than cutting ring external diameter, force application rod 6 is vertical state, be cutting ring 1 below pressure plate 5, cutting ring is that stainless steel material is made, and has sizes, the cutting ring that this device is conventional is of a size of: internal diameter 62mm, height 40mm, the thickness 2mm of cutting ring wall 3, the height of cutting edge 2 is 7mm.Force application rod 6 is designed to adjustable in length, force application rod 6 can regulate the connection distance of force application rod 6 and pressure plate 5 through the hole in the middle of bolt 9, to adapt to the cutting ring of differing heights, bolt 9 has buckle, and its effect regulates force application rod 6 through can by fixed by snap for force application rod 6 in the hole of bolt 9 behind the position of bolt 9.
When soil sampling, soil sample 4 is placed on the base 13 of cutting ring device, again cutting ring 1 edge of a knife 2 to being placed down in above soil sample 4, being pulled upwardly handle 8 again makes pressure plate just be placed on above cutting ring 1, slidable adjustment sleeve pipe 10 again, makes force application rod 6 vertically sagging, firmly pulls down fixed handle 8, allow pressure plate 5 evenly exert pressure to cutting ring 1, cutting ring 1 is entered in soil sample 4.
