Between the auxiliary pressing plate of described return and positioning and guiding bar and between pressure biography cylinder and mode positioning and guiding sleeve, be clearance fit.
The auxiliary pressing plate of described return and pressure pass cylinder connected mode for welding.
Described pedal adopts and is threaded with hydraulic cylinder initiatively, and pedal and initiatively hydraulic cylinder number be two, be symmetricly set in the both sides of main anchor.
Between described feeding hydrocylinder and balance pressing plate, it is pin joint.
Described pedal is the pedal that can trample for people.
The utlity model has following beneficial effect: the prior art of comparing, what the utility model arranged on base by employing passes through initiatively hydraulic cylinder of foot-controlled, control the oil mass in feeding hydrocylinder, and then control the fetching earth of tool changing, because the power applying on pedal is fixed, thus guaranteed to fetch earth steadily, avoid the generation of disturbance, improved the accuracy and the reliability that fetch earth and measure, and this apparatus structure is simple, easy operating.And the husky sample of getting more approaches original-pack, and measuring accuracy is higher.
Further, because base is fixed by locating steel needle, guaranteed stability and the reliability of device operation.
Further, because positioning and guiding bar adopts and is threaded with base, thereby guaranteed the stability that device moves.
Further, owing to being clearance fit, make both can realize interior slip.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1: base, 2: initiatively hydraulic cylinder, 3: pedal, 4: return auxiliary spring, 5: hydraulic oil pipeline, 6: feeding hydrocylinder, 7: main anchor, 8: balance pressing plate, 9: return is assisted pressing plate, 10: positioning and guiding bar, 11: adjustable positioning and guiding sleeve, 12: locating steel needle, 13: cutting ring, 14: pressure passes cylinder.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, the utility model comprises through locating steel needle 12 and is fixed on base in sand base 1 and is fixedly installed on main anchor 7 on base 1 and hydraulic cylinder 2 initiatively, and on main anchor 7, be fixed with the rigidity hydraulic oil pipeline 5 that one end is connected with active hydraulic cylinder 2, the other end of hydraulic oil pipeline 5 is connected with the feeding hydrocylinder 6 in main anchor 7, initiatively hydraulic cylinder 2 is bolted on main anchor 7 with feeding hydrocylinder 6, and bolt model is M10, hydraulic oil pipeline 5 fastens on main anchor 7 by pipeline, balance pressing plate 8 and return for pin joint between feeding hydrocylinder 6 belows are disposed with are assisted pressing plate 9, and the auxiliary pressing plate 9 of return is fixing by positioning and guiding bar 10, for clearance fit, the other end of positioning and guiding bar 10 adopts to be threaded and is fixed in base 1, the below of the auxiliary pressing plate 9 of return is closely provided with successively pressure and passes cylinder 14 and cutting ring 13, and cutting ring 13 embeds in sand base through base 1, and be provided with adjustable positioning and guiding sleeve 11 on the sidewall of pressure biography cylinder 14 and cutting ring 13, and it is clearance fit that pressure passes between cylinder 14 and adjustable positioning and guiding sleeve 11, initiatively hydraulic cylinder 2 numbers are two, are symmetricly set in the both sides of main anchor 7, be provided with and adopt the pedal 3 being threaded on it, the auxiliary pressing plate 9 of return passes cylinder 14 connected modes for welding with pressure.
The injection active force of utilizing human body weight to bury as cutting ring 13, utilizes hydraulic cylinder, by hydraulic oil, human bady gravitational is passed to cutting ring 13.The single pin of operating personnel steps down on pedal 3, by active hydraulic cylinder 2, the weight transmitting of human body is arrived to feeding hydrocylinder 6, and now the hydraulic oil in active hydraulic cylinder 2 flows into feeding hydrocylinder 6 by hydraulic oil pipeline 5.Feeding hydrocylinder 6 moves downward, and by balance pressing plate 8, promotes pressure biography cylinder 14 and moves downward along adjustable positioning and guiding sleeve 11, promotes the husky bases of cutting ring 13 injection.Owing to utilizing this medium of hydraulic oil to transmit human bady gravitational, make feed mechanism gentle movement, guarantee that cutting ring 13 steadily buries, do not vibrate, there is not disturbance in soil sample, more approaches undisturbed soil.After the husky base of cutting ring 13 injection, 4 energy storage of return auxiliary spring, when operator removes after gravity, return auxiliary spring 4 is assisted pressing plate 9 to promote pressure by return and is passed cylinder 14 and feeding hydrocylinder 6 returns.Now, hydraulic oil flows into initiatively hydraulic cylinder 2 by feeding hydrocylinder 6, and then completes the overall process that fetches earth.
In mobile and transportation, except the hydraulic system being formed by hydraulic cylinder, conduit under fluid pressure, hydraulic oil, can dismantle Assembling after reaching the spot.In hydraulic system, building block is forbidden dismounting, the mechanism's poor fit brought that prevents that hydraulic means from damaging and relative position changes, and then cause sampling unsuccessfully.
