Existing rotary hemorheology sampling probe cleaning performance is poor in order to overcome, the debris deficiency big to sample effects in the electromagnetic type filling sample technology pipeline; The utility model provides a kind of full-automatic hemorheology sampling system; This a kind of full-automatic hemorheology sampling system cleans sampling probe in the sampling probe moving process of filling gap; Has the efficient height, the advantage that cleaning performance is good.
The utility model solves the technical scheme that its technical matters adopted: a kind of full-automatic hemorheology sampling system; It is characterized in that: above sample disc and measuring mechanism, be provided with horizontal slide rail and the horizontal drive mechanism supporting with it; Be equipped with the sampling probe assembly cross sliding clock can horizontal slide rail on move, cross sliding clock is provided with sampling probe vertical moving drive unit and sampling probe cleaning part.
Described horizontal drive mechanism comprises the horizontal driving pulley and the horizontal driven pulley that is positioned at the horizontal slide rail other end on the horizontal step motor shaft that be installed in that is positioned at horizontal slide rail one end, between two belt pulleys horizontal belt is housed.
Be equipped with on the described cross sliding clock that horizontal linear bearing horizontal belt passes and fixing from the horizontal linear bearing.
Described sampling probe assembly vertical moving drive unit comprise be installed in cross sliding clock up and down the vertical driving pulley at two ends with vertical driven pulley be installed in the vertical strap on two belt pulleys; Vertical driving pulley is installed in the rotating shaft of the vertical stepper motor that is fixed on cross sliding clock; Also be fixed with vertical slide rail on the cross sliding clock; One end is being fixed the sway brace of sampling probe, and the other end is fixed on the vertical strap, passes through in the vertical line bearing of vertical slide rail from be installed in sway brace.
Described sampling probe cleaning part is installed in the cross sliding clock bottom, and the cleaning fluid IO interface is housed on the cleaning part, and sampling probe passes from cleaning part.
The beneficial effect of the utility model is employing level and vertical movement mechanism and in the bottom of cross sliding clock the sampling probe cleaning part has been installed; Realized again carrying sample for measuring mechanism; During the return the automatic cleaning of sampling probe both improved the detection speed of hemorheology detector; Guaranteed that again sampling probe is in time cleaned, guaranteed the accuracy of check data.

Embodiment
The embodiment of the utility model is, and is as shown in the figure:
The course of work of the utility model is: sample disc stepper motor 12 drives the position, hole that sample disc 11 rotates to needs measurement, sample test tube 15 is rotated to assigned address, both the shortest position of range observation mechanism 13 air line distances; 16 rotations of horizontal stepper motor, with cross sliding clock 5 together with sampling probe 17 move to sample tube 15 directly over, sampling probe 17 runs down to the bottom of sample tube 15 under the drive of vertical stepper motor 10; The outside syringe pump equipment that sampling probe 17 upper ends are connected with solenoid valve through the silica gel pipeline is done the action of suction and is drawn sample, and after sample was drawn and finished, the external unit that two pipe connecting pieces of sampling probe cleaning part 9 connect was respectively started working; Both constantly had cleaning fluid to get into the inside of sampling probe cleaning part 9, cleaning fluid is constantly siphoned away by the negative pressure of negative pressure equipment generation again simultaneously, in this process; Cleaning fluid can reach the effect of cleaning around the outer wall motion of sampling probe 17, and sampling probe 17 upwards runs to the centre position of sampling probe cleaning part 9 under the drive of vertical stepper motor 10; In this process; The sample that unbroken cleaning fluid adheres on promptly can the outer wall with sampling probe 17 in the sampling probe cleaning part 9 cleans up, and sampling probe 17 is up to assigned address, and the external unit that two pipe connecting pieces of sampling probe cleaning part 9 connect respectively quits work; Horizontal stepper motor 16 rotations; Drive cross sliding clock 5 move to the right measuring mechanism 13 directly over, in this process, because after outside negative pressure equipment stops; Negative pressure also remaining in the pipeline will be clean with the sample suction that the lower end of residual cleaning fluid in the sampling probe cleaning part 9 and sampling probe 17 is a spot of and cleaning fluid is contacted; Vertical stepper motor 10 rotations, drive sampling probe 17 move to downwards measuring mechanism directly over assigned address, the outside syringe pump equipment that sampling probe 17 upper ends connect through the silica gel pipeline is done and is pushed away the inside that the motion of telling is filled into sample measuring mechanism 13; Measuring mechanism 13 beginning measuring processes; Vertical stepper motor 10 rotations drive the middle position that sampling probe 17 is up to sampling probe cleaning part 9, and the negative pressure tube coupling spare in two pipe connecting pieces of sampling probe cleaning part 9 is connected with outside negative pressure equipment; Negative pressure is caused in the sampling probe cleaning part 9; Simultaneously, the equipment of the outside filling cleaning fluid that sampling probe 17 upper ends connect begins to sampling probe 17 inner filling cleaning fluids, and the cleaning fluid of filling is through the inwall of sampling probe 17; Take out by the negative pressure in the sampling probe cleaning part 9 at last; This process both can clean up the sample that adheres in sampling probe 17 inwalls, and the residual cleaning fluids suction that the negative pressure equipment that is connected with sampling probe 17 upper end pipelines can be inner with sampling probe 17 is clean, and so far the process of sample collecting, filling, cleaning all finishes.
