Sample drawer, 1/4 part of sample drawer, left 1/8 part of sample drawer, right 1/8 part of sample drawer, upper vibrator group, lower vibrator group and motion are flat
Platform；It is in alternate arrangement that A separate slots and B separate slots are set in riffles at different levels；The upper vibrator group is located at the two ends of one-level riffle, under
Vibrator group is respectively provided at the two ends of left three-level riffle and right three-level riffle；Whole reduction device is fixed on the moving platform,
The motion platform can make straight line and come and go vibration so that reduction device integrally moves reciprocatingly along separate slot axis, it is ensured that upper level two
Point device A separate slots and B separate slots increment are back and forth uniformly sprinkled into this grade of riffle along the axis of the division separate slot of next stage riffle
In A, B separate slot.
The multistage automatic riffle of powder sample of said structure passes through to arrange three-level riffle, and in the first order and the third level
Riffle two ends arrange vibrator, it is ensured that whole reduction device is in during operation dither state, so that powder material
Do not adhere to, accumulate or put up a bridge and block riffle separate slot；Whole reduction device is fixed on straight line and comes and goes on oscillating movement platform so that
Reduction device integrally moves reciprocatingly along separate slot axis, so as to drive the A grooves and B grooves discharging of every one-level division unit respectively along
Corresponding next stage division unit separate slot axis is back and forth uniformly sprinkled into, it is ensured that per the representativeness of one-level division.
The multistage automatic riffle of powder sample of said structure has the advantages that：
1. by installing vibrator, it can be ensured that riffle separate slot does not gather materials, do not block during division.
2. by coming and going rocking platform, it can be ensured that the sample representativeness of multistage division, every grade of reduction error≤3%.
3. drawer is accepted by rationally arranging multistage riffle unit and reasonable Arrangement sample, realizes selecting former as needed
Part sample of 1/2,1/4, the 1/8 of sample weight, so as to realize automatic, quick division.
The multistage automatic riffle of this utility model powder sample passes through to arrange three-level riffle, for during powder sample division
Division can respectively accurate division go out former state weight 1/2,1/4,1/8 part sample, division speed is fast, reduction error≤3%,
With the characteristics of quickly, efficiently and accurately division.

Specific embodiment
With reference to the accompanying drawings and detailed description automatic riffle multistage to this utility model powder sample makees further
Describe in detail.
The multistage automatic riffle of this utility model powder sample shown in Fig. 1-Fig. 4 is a reduction device arranged by three-level,
It includes one-level riffle 1, the second from left level riffle 2, right two grades of riffles 3, left three-level riffle 4, right three-level riffles 5,1/2
Part sample 6,1/4 part of sample drawer 7 of drawer, left 1/8 part of sample drawer 8, right 1/8 part of sample drawer 9, upper vibrator group 10, lower vibrator group
