Embodiment
Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
Shown in Fig. 1 ~ 3, the dry-mixed mortar sampler comprises telescoping mechanism, adapter sleeve 60, automatic aligning mechanism 50, piston 20 and piston cylinder 10, and wherein telescoping mechanism can be cylinder 30.The stiff end of cylinder 30 and hand-operated direction valve 32 are spirally connected, the air inlet of hand-operated direction valve 32 may command cylinders 30 with give vent to anger.The link end of the piston rod 31 of cylinder 30 is bolted with adapter sleeve 60, on the external thread of piston rod 31, also is arranged with set nut 33, and pretension and the effect of loosening can be played to adapter sleeve 60 in the end of set nut 33 butts to adapter sleeve 60.
The inwall of the connecting hole of the link of piston 20 is the raceway 21 of arc along circumferential direction formation with ball mounting groove 63 corresponding cross sections, forms installing space between raceway 21 and the corresponding ball mounting groove 63.The connection hole wall upper edge radial direction of piston 20 offers and ball mounting groove 63 corresponding ball installation channel 22, and ball installation channel 22 internal fixation are provided with backstop plunger 52.In the present embodiment, ball installation channel 22 is the cylindrical hole structure.
The defeated material end end of piston 20 is provided with shrouding 23 through screw retention.Aforesaid piston rod 31, automatic aligning mechanism 50, adapter sleeve 60, piston 20 and shrouding 23 all are set in the piston cylinder 10; First end of piston cylinder 10 is connected through bolt with the stiff end of cylinder 30; Second end of piston cylinder 10 stretches into and is fixedly installed in the sample connection 71 on the dry-mixed mortar stirring machine host housing 70, and is communicated with this sample connection 71.Be provided with the interface that is communicated with stopple coupon 40 near dry-mixed mortar stirring machine host housing 70 places on piston cylinder 10 sidewalls, and piston cylinder 10 is fixing with stopple coupon 40 welding.Preferably, stopple coupon 40 is inclined tube or bend pipe.The periphery wall of piston 20 periphery walls and shrouding 23 all fits with piston cylinder 10 internal perisporiums, and piston 20 can slide by piston cylinder 10 in the driving lower edge of piston rod 31.
The telescoping mechanism here is not limited to cylinder, also can be telescopic oil cylinder or other have can straight-line flexible end device.
When automatic aligning mechanism 50 is installed; Earlier a plurality of balls 51 are pushed installing space from ball installation channel 22; Make between a plurality of balls 51 evenly distributed; Then backstop plunger 52 is fastened in the ball installation channel 22 and also suitably tightens, the radial motion with restriction ball 51 can only be rolled ball 51 in installing space.Preferably, wringing fit between ball mounting groove 63, ball 51 and the raceway 21.
This structure aligning principle is similar to the self-aligning ball bearing structure; Be that with the difference of self-aligning ball bearing raceway is two raceways and the steel ball fixed support is arranged in the self-aligning ball bearing; And raceway is single raceway in the aforesaid structure, and the steel ball fixed support need be set, and can realize automatic aligning equally.
Because the existence of automatic aligning mechanism 50; When the piston rod 31 of cylinder 30 with after adapter sleeve 60 is connected; Piston rod 31 axially with piston 20 axially between formation one angle; And line between same radially two ball 51 centers and piston 20 radially between form an angle β, the interface that is communicated with stopple coupon 40 that is provided with on through piston cylinders 10 sidewalls when piston 20 and when tilting, piston rod 31 can also not tilt thereupon; The stuck phenomenon of interface that therefore, can not cause piston 20 being communicated with owing to the inclination of piston rod 31 with stopple coupon 40.After piston 20 passes through this interface; Because piston rod still is in horizontality, under the automatic aligning effect of ball 51, piston 20 beginnings are from NMO correction; And finally realize the right alignment between piston 20 and the piston cylinder 10, guarantee piston 20 steadily moving in piston cylinder 10.In addition; Even in the installation process,, cause between piston rod 31 and the piston 32 to have certain angle owing to reasons such as alignment errors; Be not positioned at same axis direction; Under the corrective action of automatic aligning mechanism, still can guarantee the right alignment between piston 20 and the piston cylinder 10, thereby guarantee piston 20 steadily moving in piston cylinder 10.
In the time of need carrying out sampling operation; Through 30 work of operation hand-operated direction valve 32 control cylinders; Drive piston 20 and do rectilinear motion along piston cylinder 10, when piston 20 was positioned at the A position, the sample connection 71 on the host housing 70 of stopple coupon 40 and dry-mixed mortar stirring machine formed open circuit; Be sample this moment, can utilize the good flowability of dry-mixed mortar to take a sample.When piston 20 is positioned at the B position; Sample connection 71 on the host housing 70 of stopple coupon 40 and dry-mixed mortar stirring machine forms closed circuit; Be non-sample this moment, and owing to piston 20 periphery walls and piston cylinder 10 internal perisporiums fit, so all acquired samples all are advanced sample connection 71; Can residual dry-mixed mortar material in piston cylinder 10, just can not influence the accuracy of sub-sampling down yet.
According to another embodiment of the invention; A kind of dry-mixed mortar stirring machine is provided; This dry-mixed mortar stirring machine comprises shell 70, be arranged on the shell 70 sample connection 71 and aforementioned in any dry-mixed mortar sampler; The piston cylinder 10 of this dry-mixed mortar sampler stretches in the sample connection 71, is fixedly connected with mount pad 11 on the periphery wall of piston cylinder 10, and the dry-mixed mortar sampler is fixedly installed on the shell 70 through mount pad 11.Preferably, be provided with backing plate 12 between mount pad 11 and the shell 70.
From above description; Can find out that the above embodiments of the present invention have realized following technique effect:, compare to traditional one-piece piston and piston rod between piston rod and piston through automatic aligning mechanism is set; Make between the axial direction of axial direction and piston of piston rod and can produce the angle in the certain limit; When piston motion to piston cylinder during with the position run-off the straight of getting that material pipe is connected, piston rod can be with tilting of the piston, piston through piston cylinder with get expect to manage the position that is connected after; Avoided piston that the jam phenomenon takes place in the motion process in piston cylinder, made dry-mixed mortar sampler more stable work, smooth and easy.Mounting process to cylinder requires to decrease simultaneously, and the piston rod of cylinder and cylinder axial direction can have the angle of certain limit, and the same motion of piston in piston cylinder the jam phenomenon can not take place, and is able to the purpose of sampling smoothly.But the dry-mixed mortar stirring machine of the dry-mixed mortar sampler of this aligning has been installed; With respect to the dry-mixed mortar stirring machine that does not dispose professional sampler; It is convenient to take a sample, can be at any time according to the stirring material proportion in the experimental result adjustment dry-mixed mortar stirring machine main frame.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
