Abstract

The utility model relates to a core extracting machine in spodosol, which is special equipment for the field coring of the buildings of highways. In the buildings of highways, the detection of various parameters of the spodosol of road beds can provide important basis for the equipment and the maintenance of road surfaces, and at present, the samples obtained by indoor simulating articles and in the mode of borrowing with an annular-knife method can not maintain the original state of the spodosol detected. The utility model comprises a base, an upright post, a transverse support frame, a motor, a gear box and a coring head can complete the downward drilling coring with high-speed rotation. The utility model has high speed and accurate specification; the sample maintains the original state of the spodosol measured; the utility model reflects the construction quality of the buildings of road bed authentically scientifically, and can save the expenses of experiment about 60%.

Description

Core sample extracting machine in spodosol

The utility model belongs to road engineer Instrument, is can be for the special equipment of getting core in the highway structure on the spot.

In the highway structure process, must the parameters such as solidity, dry capacity, void ratio, sinkage, compressive strength of hitting of roadbed dirt be detected, when the design and the maintenance of highway pavement provides important basis.Present detection method has to be produced sample at lab simulation and detects, and as producing grey soil sample with small-sized compaction test apparatus, detects the compressive strength, water content, dry capacity of dirt etc.; Or take out sample with core cutter method capacity test instrument (being commonly called as the core cutter method soil sampler), this method is cutting ring directly to be pressed into handle or to squeeze in the soil with hammering, this method also has more drawback, because variation has taken place the dirt situation later by hammering, air space ratio, soil pressure etc. all has been subjected to influence to a certain extent.As fully visible, no matter be that lab simulation sample or existing core cutter method soil sampler are gathered every index that sample all can not reflect roadbed dirt more objectively on the spot, road pavement design and maintenance bring certain influence.

The utility model proposes a kind of novel grey core machine, can get core exactly fast by specification at the scene, materials and can reflect the real conditions of roadbed dirt, improved the science, the reliability that detect data.

This dirt corning machine by base, column, lateral frame, motor, transmission case, get core print and form.

Accompanying drawing one is the utility model single unit system structural representation

Accompanying drawing two is got the structural representation of core print for the utility model

Among the figure: 1, base 2, road wheel 3, road wheel extension spring 4, guide pile 5, principal post 6, lateral frame 7, lifting coarse screw 8, circle 9 is drawn at the end, transmission case body 10, motor 11, driving gear 12, driven gear 13, pilot sleeve 14, lifting shaft 15, lifter wheel 16, tooth bar tube 17, bearing 18, lifting handle 19, main shaft 20, get core print 21, casting groove 22, cutter head 23, get the core print staving

Existing accompanying drawings technical solution of the present utility model:

Base 1 is plate casting or the steel plate of pros or rectangle tool constant weight, and the plate face has circular hole betwixt freely movable up and down for getting core print. The bottom at 1 four angles of base is equipped with road wheel 2, guide pile 4, road wheel is higher than guide pile number centimeter, between road wheel 2 and the base 1 road wheel extension spring 3 is installed, column 5 is vertically mounted on the centre position of seating plane one side, lateral frame 6 one ends are enclosed within on the column, can vertically move, and make it be fixed on as required a certain height and position of column 5 by lifting coarse screw 7, the column bottom is installed with end ring washer 8, its effect is the whereabouts extreme position of restriction lateral frame 6, make and get core print 20 just in time drops on sampling place before work ground surface, the top of lateral frame 6 is equipped with motor 10, the below is transmission case body 9, transmission case body includes driving gear 11, travelling gear 12, pilot sleeve 13, lifting shaft 14, lifter wheel 15, tooth bar tube 16, metal (upper 17, main shaft 19 vertically passes transmission case body, and place in the pilot sleeve 13, the lower end connects gets core print 20, one end of lifting handle 18 connects in lifter wheel 15 in transmission case body, the other end is exposed at outside the transmission case body, so that descending operation. Getting core print 20 forms by getting core print staving 23, casting groove 21, cutter head 22 3 parts, get the short barrel of upper sealing lower open mouth that core print staving 23 is made for the Fine Steel Casting iron material, upper circle diameter is slightly less than lower circle diameter, the outer wall of staving has several and becomes 50-80 degree angle auger type dumping groove 21 with lower circumferential end surfaces, the convolution of cutting soil can be discharged to ground, get 23 times circumference of core print staving near every Casting groove place all is inlaid with cutter head 22, and cutter head is Hardmetal materials, can cut dirt when getting core print from the downward High Rotation Speed in the face of land, and the dirt of getting in the core print staving is separated with original position dirt.

The utility model embodiment:

The scene that cleaning earlier desires to get grey soil sample, rely on road wheel 2 that this dirt corning machine is pushed into the scene, because road wheel extension spring 3 is housed can play road wheel 2, guide pile 4 lands, the corning machine location, unscrew lifting coarse screw 7, lateral frame 6 falls to end ring washer 8, motor 10, transmission case body 9, get core print 21 all falls thereupon, get core print and pass base circular hole land to sampling place ground, connect power supply, driving gear 11 drives driven gear 12, the internal spline of driven gear drives external splines (spline can't the be represented in the drawings) main axis rotation of main shaft, getting core print rotates synchronously, holding lifting handle 18 pressurizes downwards, lifter wheel 15 and 16 engagements of tooth bar tube, because of main shaft pilot sleeve 13 is interference fit with lifting shaft 14, main shaft also moves down in rotation, getting core print 20 just creeps into to dirt under the effect of cutter head 22 fast, cut apart soil and drain into ground by casting groove 21, enter underground fully when getting core print, lift lifting handle 18 and fix lateral frame and just finished the overall process of taking out grey soil sample by the thick bar screw 7 of lifting, rotating speed (transmission speed ratio is 2.5:1) with 560 rev/mins in the practice is got core print specification and 50mm * 50mm, 68mm * 52mm, 100mm * 52mm(gets core print and can change according to the size of sample requirement) main shaft decline length can reach about 80mm, repeatedly takes out the grey soil sample of requirement up to specification.

The utility model has the advantages that and to arrive on-the-spot direct sample, get the original condition that core speed is fast, specification accurate, sample needing to have kept detection site dirt, it is truer, reliable that roadbed dirt parameters is measured, can reflect objectively the roadbed Construction Quality, for design and the maintenance of highway pavement provides scientific basis, this corning machine saving test fund about 60 percent has bigger society and economic benefit.
