Description of drawings
Fig. 1 is main cut-open view of the present utility model.
Fig. 2 is side view of the present utility model.
Embodiment
Such as Fig. 1, shown in 2, spiral sampling head comprises urceolus 1, periphery at urceolus 1 is provided with spiral deflector 5, the lower surface of urceolus is provided with tooth form cutting alloy 8, described urceolus 1 is hollow form, in urceolus 1, be provided with axle 3 and piston rod 13, one end of described piston rod 13 is installed on the bearing seat by bearing 11, one end stretches out cover plate 12 outer and cylinder (or oil cylinder) phase configuration of urceolus, the upper end of axle 3 is connected by bolt with bearing seat, the lower end is connected with drill bit 6, and wherein, drill bit 6 is taper bit, periphery at taper bit is provided with spiral wimet 7, also be installed on circular scraper plate 4 on axle 3, the inwall of the periphery of scraper plate 4 and urceolus 1 fits, and the upper surface of the lower surface of scraper plate 4 and drill bit 6 and the inwall of urceolus form between enclosed sampling 9.Be provided with axial limiting hole 10 at urceolus, be provided with locating piece 2 in the periphery of bearing seat, by the contraction of control piston bar 13, locating piece 2 can slide up and down in spacing hole 10.
The course of work of the present utility model is: sampling head is under the effect of whirligig and jacking gear, integral body is done the backspin motion, because the lower end of piston rod 13 is equipped with bearing 11, so piston rod 13 in sampling head backspin motion process, only descends with sampling head synchronously.Because the whole relative position of sampling head is constant, then by 9 being spaces of a relative closure between the lower surface of the inwall of urceolus 1, axle 3, scraper plate 4 and sampling that drill bit 6 upper surfaces form.In the whole backspin process of sampling head, the dentition formula cutting alloy 8 of the lower end of urceolus 1, can carry out cutting and crushing to material, reduce the resistance of urceolus 1 backspin, and the spiral wimet 7 on the drill bit 6 and the spiral deflector on the urceolus 15 make the top layer material float along helix, to guarantee the accuracy of sampling.
When arriving sampling depth, the jacking gear of whole sampling head stops to descend, and axle 3, scraper plate 4, drill bit 6 continue to carry out synchronous rotary with urceolus 1 under the effect of locating piece 2.At this moment, piston rod 13 stretches out (decline), make axle 3, scraper plate 4, drill bit 6 is done vertical descending motion in the spacing hole 10 synchronously vertically with locating piece 2, when piston rod 13 stretches out fully, the upper plane of drill bit 6 is lower than the lower surface of urceolus 1, namely 9 lower end becomes the opening shape between the sampling, keep the invariant position of piston rod 13 this moment, and make whirligig drive urceolus 1 reverse rotation, make material descend and be deposited on the upper plane of drill bit 6 along spiral deflector 5, after after a while, piston rod 13 shrinks (rising), make piston rod 13 get back to initial position, 9 have just become again a confined space of filling material between sampling like this.Utilize at last jacking gear and whirligig, make whole sampling head get back to initial bit.
When sampling head carries out discharging, sampling head is moved to the aggregate tube top, and utilize whirligig drive urceolus 1 to be rotated in the forward, piston rod 13 stretches out, axle 3, drill bit 6 are done the backspin motion in pilot hole 10 under the effect of locating piece 2, open 9 lower end between sampling, material is all collected in the aggregate tube under the rotary centrifugal force effect of axle 3 and drill bit 6.In whole discharge process, owing to be provided with scraper plate 4 on the axle 3, scraper plate 4 can sweep remaining in urceolus 1 material all around, has ensured the completeness of discharging, has avoided the generation of mixed sample phenomenon.
In the material transportation process, be hermetic between sampling of the present utility model, effectively avoided the situation of material from leakage to occur, and the top be provided with scraper plate between sampling, has greatly improved the completeness of discharging, avoided mixed sample phenomenon to occur; Be provided with spiral deflector on the urceolus of sampling head, can effectively avoid the bonding situation that causes adopting the sky sample between sampling that can't enter of material to occur, enlarged the scope that this sampling head can be taked material moisture.
In sum, the utility model is simple and compact for structure, and rationally processing and fabricating is easy, and parts are installed and changed simply, are applicable to the collection of the samples such as coal, ore.
