Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in embodiment of the present utility model is entered Row clearly and completely describes, it is clear that and described embodiment is only the utility model part of the embodiment, rather than all Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise Lower obtained every other embodiment, belong to the scope of the utility model protection.

As Figure 1-Figure 2, a kind of soil sampling device for road construction of highway engineering, support 1, drilling pipe 2, driving electricity are mainly included Machine 3, shuttle 4.

Its medium-height trestle 1 includes lower supporter 11, column 12, ceiling hold 13, electric machine support 14, and lower supporter 11 is placed on bottom surface On, it is a monoblock flat board, column 12 shares four, is separately mounted at the corner of lower supporter 11, is installed at the top of column 12 There is a ceiling hold 13, electric machine support 14, which is in, to be offered hole and supply four root posts 12 between lower supporter 11 and ceiling hold 13, and at corner Pass through, a hand wheel drive 5 is installed in the upper surface of ceiling hold 13, is installed with the upper surface of electric machine support 14 The rack 6 of a piece vertical direction, coordinate between hand wheel drive 5 and rack 6 for rack-and-pinion, driven and filled by rotation hand wheel 5 handwheel is put, realizes sliding up and down for electric machine support 14.

Motor 3 is arranged on the upper surface of electric machine support 14, passes through motor positioned at the centre position of upper surface, output shaft Support 14 downward, is provided with a shuttle 4, the lower section installation of the shuttle 4 on the output shaft of motor 3 There is a drilling pipe 2, offer a resigning hole relative to the position of drilling pipe 2 on lower supporter 11 passes through for drilling pipe 2.Wherein drilling pipe 2 bottom is augers 21, and helical blade 22 is fixedly installed in the side of drilling pipe 2, and described helical blade 22 prolongs always Extend the inside of shuttle 4.

In sampling, because thering is part helix blade 22 to be on ground, under shuttle 4, soil-like now As long as product, which somewhat shake, to be dropped from helical blade 22, the sample that can be reached in shuttle 4 is few, in order to keep away Exempt from helical blade 22 and be directly exposed to outdoor, a pillar 7 is included in the periphery of drilling pipe 2, the pillar 7 is also mounted at sample appearance The bottom of device 4, and the top of pillar 7 expands outwardly, and carry sawtooth.Shuttle 4 is driven to rotate by motor 3, from And the synchronous rotary of pillar 7 and drilling pipe 2 is realized, the sawtooth of the bottom of pillar 7 more easily can be such that soil separates by spiral The transmission of blade 22 comes up.

After taking sample, the drilling pipe 2 of sampling needs quickly to release in soil, to prevent sample from sliding, so Lifting arm 8 is installed with the upper surface of electric machine support 14, lifting arm 8 there are four, is separately mounted to the four of electric machine support 14 Angle, through ceiling hold 13, and block 81 is installed at top, pressure is installed between the upper surface of block 81 and ceiling hold 13 Contracting spring 9, a upward tension force is applied by the compression spring 9 compressed so that the power of the manual rotation hand wheel of people will reduce Much.

Because shuttle 4 is and then motor 3 while rotation in the present embodiment, produced to reduce due to rotation Raw centrifugal force, the shuttle 4 in the present embodiment is transparent cylindrical shape.It is not a needs in view of sampling process The process of highly intensive labour, its motor need not select heavy-duty motor, so the motor 3 in the present embodiment selects stepping Motor, its input voltage selection 36V.

Sampling is carried out in same place, it is sometimes necessary to Discontinuous sampling is carried out over a long distance, for side Just disassembled for transport, between lower supporter 11 and column 12, between column 12 and ceiling hold 13, between lifting arm 8 and block 81, lifting Coordinated between bar 8 and electric machine support 14, between pillar 7 and shuttle 4, between drilling pipe 2 and shuttle 4 using screw thread.

Operation principle：After sampler in the present embodiment is assembled, motor 3 is powered, can be manually rotated hand The handwheel of dynamic drive device 5, in the presence of rack and pinion engagement transmission, overcome the tension force of compression spring 9, rack 6 is transported downwards It is dynamic, while electric machine support 14 is moved downward, drilling pipe 2 is sampled, and sample is sent into sample by helical blade 22 holds In device 4；After sampling terminates, the opposite handwheel for reversely rotating manual driving device 5, while the work of the tension force in compression spring 9 Under, the motion upwards quickly of electric machine support 14, lifting goes out ground to drilling pipe 2 within a short period of time.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
