Description
Technical field
The present invention relates to civil engineering sampling instrument field, particularly relate to one and fetch earth and cut sampling 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 cutting ring, 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 screw to fetch earth and cut sampling device, cutting ring is pressed in the soil body by the thrust produced by bolt rotary, the present invention improves existing cutting ring, apparatus of the present invention comprise cutting ring seat and the cutting ring that fetches earth, a separable screw rod propulsion plant is increased at the cutting ring afterbody that fetches earth, here screw rod propulsion plant comprises cutting ring seat top board, and the support column that be fixedly connected with vertical with base, cutting ring seat top board is positioned at support column top and has dismountable flexible connection with support column, the middle position of cutting ring seat top board has the bearing of embedding, female steel pipe is fixed in the interior pipe of this bearing, this steel pipe to stretch out outside bearing and free to rotate on bearing, steel pipe top is fixed with a rotating disk, force application rod is fixedly connected with pressure plate, it is cutting ring below pressure plate, when soil sampling, first take off cutting ring seat top board from support column, soil sample is placed on and cuts on the base of sampling device, then the blade of cutting ring to being placed down in above soil sample, and to installing ring tool rest top board on support column, rotating rotating disk adjustment again makes force application rod vertically move up and down, and allow pressure plate touch cutting ring, cutting ring seat top board is fixed on the support columns, rotates rotating disk and pressure plate can be made to move down, evenly exert pressure to cutting ring, cutting ring is entered in soil sample.
Be the further improvement of technique scheme, fluted in the pressure plate plane of the contact position of pressure plate and cutting ring, 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.
The present invention achieves following technique effect:
By the present invention, cutting ring is improved, smoothly cutting ring can be pressed in hard soil sample by screw rod thrust and materials.Overall sampling process uniform force application, improves efficiency and the quality of sampling.
Accompanying drawing explanation
Fig. 1 is that screw of the present invention fetches earth and cuts sampling 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 screw rod device for exerting additional on traditional cutting ring that fetches earth, and utilizes rotation thrust and the lever force-saving principle of screw rod, greatly increases the pressure on cutting ring, cutting ring successfully can be pressed in hard soil sample and obtain sample.
Embodiment 1:
Design a screw of the present invention to fetch earth and cut sampling device, see Fig. 1, design the sampling bench that can be installed screw device, sampling bench comprises: diameter is 100mm, the round metal bench-type base 13 of thick 10mm, it is highly the column type support column 12 of 100mm that base 13 edge homogeneous vertical fixes 4 diameter 20mm, support column 12 upper end connects a cutting ring seat top board 8, main stressed member when this cutting ring seat top board 8 is exactly screw rod of the present invention propelling, cutting ring seat top board 8 is connected by dismountable with support column 12, cutting ring seat top board 8 can be installed from support column 12 easily and pull down, as fixed by buckle or magnet.Cutting ring seat top board 8 is the metal round platform of 100mm, thick 18mm for diameter, is made up of rigidity hard material, can turn to bear larger pressure indeformable.
The middle position of cutting ring seat top board 8 and circle centre position embed an external diameter 40mm, internal diameter 20mm, the bearing 10 of height 20mm, female steel pipe 7 is fixed in the interior pipe of this bearing, fixed form can be welding, the external diameter of steel pipe 7 is 20mm, internal diameter is 15mm, be highly 50mm, this steel pipe stretches out the long 30mm of part outside bearing and free to rotate on bearing, steel pipe top is fixed with a rotating disk 9, fixed form can be welding, rotating disk 9 can drive steel pipe 7 to rotate on bearing 10, clock-wise fashion rotates and force application rod 6 can be made downwards to advance, force application rod 6 is fixed welding manner with pressure plate 5 and is connected, it is cutting ring 1 below pressure plate 5, when soil sampling, first take off cutting ring seat top board 8 from support column 12, soil sample 4 is placed on and cuts on the base 13 of sampling device, then the blade of cutting ring 1 to being placed down in above soil sample 4, and to installing ring tool rest top board 8 on support column 12, rotating rotating disk 9 adjustment again makes force application rod 6 vertically move up and down, and allow pressure plate 5 touch cutting ring 1, cutting ring seat top board 8 is fixed on support column 12, rotates rotating disk 9 and pressure plate 5 can be made to move down, evenly exert pressure to cutting ring 1, cutting ring 1 is entered in soil sample 4.Here the diameter of rotating disk 9 is larger, rotates more laborsaving, easilier operates hard soil sample.
