Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, the utility model comprises screw thread 21 in extension bar 1, the recessed hollow round table in extension bar lower end 11, extension bar lower end male thread 12, joint coupling 2, joint coupling, weighted lever 3, weighted lever protruding solid round platform 31, weighted lever upper end male thread 32, perching knife 4, perching knife top cover 41, perching knife top cap central bore 42, spring 43, shock plate 44, impact cylinder 45, impact cylinder step 46, perching knife shear blade 47, soil sample barrel 48.Extension bar 1 and weighted lever 3 pass through the screwed connection of joint coupling 2, and weighted lever 3 is connected with shock plate 44 through perching knife top cap central bore 42, and linking springs 43 between shock plate 44 and perching knife top cover 41, has impact cylinder step 46 in impact cylinder 45.
Extension bar 1 shaft hollow steel pipe makes to alleviate shaft weight, and extension bar upper surface is provided with protruding solid round platform, and protruding solid round platform steel is cast; Extension bar upper end external diameter car has screw thread, and its structure is the same with weighted lever 3 upper end.Extension bar 1 lower surface is provided with recessed hollow round table 11, and it is cast with steel, and extension bar lower end male thread 12 is for being connected with joint coupling 2.Extension bar 1 can be many extension bars, and its connection joint coupling 2 connects.
Joint coupling 2 hollow steel pipe makes, and extension bar 1 is connected by screw thread in joint coupling 21 with weighted lever 3.
Weighted lever 3 hollow steel pipe thicker than extension bar 1 makes, and weighted lever 3 upper surface is provided with the protruding solid round platform 31 of weighted lever, external diameter is provided with weighted lever male thread 32.The recessed hollow round table 11 of extension bar 1 lower surface inserts the protruding solid round platform 31 of weighted lever and becomes as a whole afterwards, and both connect with screw thread in joint coupling 21, and screw thread can be avoided during construction to produce stress concentration phenomenon.
Perching knife 4 is cylindrical shape, and perching knife 4 is made up of perching knife top cover 41, perching knife top cap central bore 42, spring 43, shock plate 44, impact cylinder 45, impact cylinder step 46, perching knife shear blade 47, soil sample barrel 48.Perching knife top cover 41 makes of steel plate, soil sample barrel 48, impact cylinder 45 roll with steel plate, perching knife top cap central bore 42 is had in the middle of perching knife top cover 41, weighted lever 3 shaft welds together through perching knife top cap central bore 42 and shock plate 44, perching knife top cover 41 and shock plate 44 4 springs 43 are connected, impact cylinder 45 diameter is greater than soil sample barrel 48 diameter, and impact cylinder 45 and soil sample barrel 48 junction form impact cylinder step 46, and the diameter of shock plate 44 is greater than soil sample barrel 48 diameter and is less than impact cylinder 45 diameter.
According to the degree of depth on exploration and design stratum, several extension bar 1 is connected by joint coupling 2 and weighted lever 3 and perching knife 4, insert to exploration soil layer is vertically lower, perching knife shear blade 47 is at extension bar 1, joint coupling 2, the Action of Gravity Field incision underground layer of weighted lever 3 and perching knife 4, weighted lever 3 impacts impact cylinder step 46 by shock plate 44 simultaneously, perching knife 4 is strengthened in the downward impact force action incision underground layer degree of depth, now, the spring 43 playing connection function between shock plate 44 and perching knife top cover 41 is elongated, play energy storage effect, perching knife 4 stops the moment spring of incision 43 to shrink, produce power of backwashing upwards, automatically lift on perching knife, perching knife is made to be easy to extract.For loose crushing soil layer, because perching knife 4 is columnar structured, soil layer not easily produces after entering perching knife 4 cylindrical shell and escapes native phenomenon, and soil sample is more complete, sampling quality is high.Can sample in the method for the very useful hammer of extension bar 1 for hardpan, under hammer action, extension bar 1 and the stressed of weighted lever 3 are all born by the solid round platform of projection and recessed hollow round table and are delivered to perching knife 4, screw thread only connects effect, stress can not be produced concentrate, extend the application life of luoyang spade.Upwards extract luoyang spade, soil sample is taken out.Repeat above process, until exploration is to design hole depth.
In a word, stressedly between extension bar of the present utility model and weighted lever to be born by the solid round platform of projection and recessed hollow round table, stress will be caused to concentrate to screw thread and destroy, extend luoyang spade application life.Labor intensity of operating staff is little, production efficiency is high, little to the disturbance of soil sample, soil sample taking rate is high, easy to process, sturdy and durable, is applicable to engineer geological prospecting worker and uses, be worthy of popularization.
Above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and do not depart from aim and the scope of technical solutions of the utility model, all still belong in the scope of technical solutions of the utility model.
