Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described:
embodiment one:
As Fig. 1, shown in Fig. 2, of the present utility model adjustable surely than reduction device, comprise and swing hopper 1, drive unit (spindle motor 4 and speed reduction unit), distribute disk 13 and circumferential some material-falling hoppers, swing hopper 1 to be positioned at and to distribute above disk 13 and to be connected with drive unit, distribute the material hole that disk 13 is provided with corresponding each material-falling hopper, each material-falling hopper is connected in turn and distributes bottom disk 13, this reduction device is also provided with two groups of loose-leaf fair water fins, be respectively A loose-leaf fair water fin 5 and B loose-leaf fair water fin 10, two loose-leaf fair water fins are all located at above material-falling hopper, and be connected with driving rack, material-falling hopper is divided into the hopper and abandon sample bucket of keeping sample, loose-leaf fair water fin is keeping sample hopper and abandon between sample bucket, when swing hopper 1 rotates, corresponding each material-falling hopper respectively.Swing that hopper 1 is suitable for reading is provided with ring flange 17, swing hopper 1 and supported by support 15, support 15 lower end is connected with rotating disc 16, and rotating disc 16 is connected with spindle motor 4.
As shown in Fig. 3,4,5, the design of loose-leaf fair water fin is as follows: comprise front catch 56, rear catch 57, Λ shape ridge 51, left swing page 53, right slew page and axis 58, Λ shape ridge two side edgefold connects left and right slew page downwards respectively, forward and backward catch lays respectively at the two ends of Λ shape ridge 51, and the spine of Λ shape ridge is set with axis 58, and left and right slew page is connected with Λ shape ridge flanging respectively by rotating shaft (52 and 59).This structure ensure that loose-leaf fair water fin rotating freely around axis, also ensure that left and right slew page is rotated at Λ shape ridge flanging side around the shaft.Forward and backward catch gear is loose-leaf fair water fin both sides (playing water conservancy diversion guide effect).Left and right slew page end also can be provided with the flap (play water conservancy diversion guide effect) concordant with catch.
A loose-leaf fair water fin and B loose-leaf fair water fin in loose-leaf fair water fin, be connected on A tooth bar 6 and B tooth bar 7 respectively by axis, and A, B tooth bar is all in circular arc, and dislocation is located in the outer circumference of material-falling hopper.A tooth bar is connected with stepper motor 2 through gear drive 3, and B tooth bar is also provided with identical gearing.On the arc-shaped slide rail that the axis other end of loose-leaf fair water fin is arranged on the inside circumference of material-falling hopper or chute.Rack drives loose-leaf fair water fin circumferentially moves, and the arc-shaped slide rail of opposite side or chute play supplemental support effect.
The hopper that keeps sample comprises A sample bucket and two B sample buckets, abandons sample bucket and comprises four (two be positioned at right half side do not draw), and each material-falling hopper arrangement is followed successively by according to clockwise direction: two B sample buckets, A sample bucket and four abandon sample bucket.Two loose-leaf fair water fins one are at A sample bucket 8 and adjacently with it abandon between sample bucket 11, and another is at B sample bucket 9 and adjacently with it abandon between sample bucket 12, and A, B sample bucket is the hopper that keeps sample.
Distribute disk 13 and swing between hopper 1 and be also provided with annular hopper 14, annulus hopper 14 position is corresponding in each material-falling hopper, and hopper is convenient to material to introduce distribute disk, and then enters material-falling hopper, loose-leaf fair water fin is positioned at this annular hopper, plays the effect of further division.
embodiment two:
This example on the basis of enforcement one, loose-leaf fair water fin, tooth bar and material-falling hopper quantity, can also arrange as required.
The course of work of the present utility model:
A tooth bar is contrary with B tooth bar direction of motion, and motion radian becomes 1:3 relation, as radian a and the 3a in Fig. 2.
Driving stepper motor gear case rotates, and gear case drives A tooth bar and B tooth bar to do circular motion respectively, and A tooth bar is contrary with B tooth bar direction of motion, and motion radian becomes 1:3 relation, therefore at splicing area Sa:Sb=1:3;
When designing, be 1:3 the ratio of division A sample bucket area SA and division B sample bucket area SB, formula has SA:SB=1:3;
So just have: (SA+Sa)/(SB+Sb)=1/3;
Therefore the division ratio with regard to realizing A division sample and B division sample is always definite value, realizes surely than division;
Spindle motor drives swing material-falling hopper circumferentially to move, and material is given uniformly division A sample bucket, division B sample bucket and abandons sample bucket.Realize division ratio by control step driven by motor loose-leaf fair water fin to regulate further, improve labour productive forces.
