At the center of cylinder；The material stock cylinder is placed on the division cylinder in the following, the inner cylinder is corresponding with the interior discharge port, described outer
Cylinder is corresponding with the outer discharge port；The washer is placed on above the division cylinder, and the batch meter is placed on the pad
On circle.
The reduction device of the adjustable reduction ratio, wherein the plug lower part is cock body, top is ridge body, the cock body
Shape is matched with the chute, and the ridge body is used to material evenly spreading to its two sides.
The reduction device of the adjustable reduction ratio, preferred embodiment are that the batch meter is the detachable variable diameter funnel of more piece,
It is arranged successively and is formed by a section funnel body and the detachable bell mouth size of 1-10 section, various pieces are assembled by screw thread, energy
Enough selection bore adapts to different grain size feed.
The reduction device of the adjustable reduction ratio, preferred embodiment are that the washer includes outer ring and inner lane, the inner lane
By being threadably mounted in the outer ring, the height of the washer can be adjusted.
The reduction device of the adjustable reduction ratio, preferred embodiment be, the partition is rectangle or right-angled trapezium, multiple
Flat mouth, concave cone mouth or convex cone mouth are formed at the top of the chute.
Beneficial effects of the present invention are：The symmetrically the same uniform division of chute of the invention and adjacent chute pan feeding division is arrived
The mode of different material stock cylinders reduces the error of division, using chute plug change inside and outside deposit the chute quantity of hopper to
Determine material division ratio, effectively eliminating laboratory, often the reduction error present in riffle is big and is not adjustable division ratio
Defect.

Specific embodiment
Embodiment 1
A kind of reduction device of adjustable reduction ratio, including batch meter 1, washer 2, division cylinder 3 and material stock cylinder 4, the division
Cylinder 3 includes cylinder 5, partition 6, baffle A7, baffle B8 and plug, and six partitions 6 are vertically provided in the cylinder 5 and are formed
Using the center of the cylinder 5 as equally distributed six chutes of basic point, the partition 6 is rectangle, six chutes it is upper
Portion forms flat mouth；Baffle A7 and baffle B8 are disposed alternately in the chute, and the end baffle A7 tilts down, the end baffle A7 with
Outer discharge port 9 is formed between the barrel of the cylinder 5, the end baffle B8 tilts down, in the end baffle B8 and the cylinder 5
Discharge port 10 in being formed between the heart；The material stock cylinder 4 includes inner cylinder 11 and outer cylinder 12, and the inner cylinder 11 is placed on the outer cylinder 12
Center at；The material stock cylinder 4 is placed on the division cylinder 3 in the following, the inner cylinder 11 is corresponding with the interior discharge port 10, institute
It is corresponding with the outer discharge port 9 to state outer cylinder 12；The washer 2 is placed on above the division cylinder 3, and the batch meter 1 is put
It sets on the washer 2.The plug lower part is cock body 13, top is ridge body 14,13 shape of cock body and the chute
It matches, the ridge body 14 is used to material evenly spreading to its two sides.The batch meter 1 is the detachable variable diameter leakage of more piece
