The shaft axis of two driven gears 52 clockwise to the center of circle angle between the shaft axis of the first driven gear 51,
To guarantee only select an engaged transmission between driving gear 4 and the first driven gear 51 and the second driven gear 52, i.e., actively
Gear 4 cannot simultaneously with the first driven gear 51 and the engaged transmission of the second driven gear 52.In addition, it is assumed that sampling
When component 7 is from the bottom to extreme position (sample spoon 722 is in trough and is sampled to molten iron at this time), until turning clockwise
And the angle along which being turned clockwise to is γ when being connected on claw 10, then the center of circle shared by 4 teeth area of driving gear
Angle [alpha] is equal to or slightly larger than d γ/D, wherein D is the diameter of driving gear 4, and d is the diameter of the first driven gear 51, d/D
=1/3, with guarantee driving gear 4 can just by sampling assemble 7 from after its bottom to extreme position, along turn clockwise to
It is connected on claw 10, and realizes the teeth area of driving gear 4 and the disengaging of the first driven gear 51 in moment, to avoid continuation
There is provided tilting force for sampling assemble 7 engages the rotation of driving gear 4.
On the one hand the size in teeth area, i.e. central angle alpha size corresponding to teeth area will can guarantee that sampling assemble 7 can be certainly
It after the bottom to extreme position, is overturn clockwise to being connected on claw 10, and realizes driving gear 4 and the hereafter
The engagement releasing of one driven gear 51；On the other hand to guarantee driving gear 4 cannot simultaneously with the first driven gear 51 and second
Driven gear 52 engages.In the embodiment, the angle of α, β and γ are selected as respectively, α=70 °, β=90 °, γ=210 °, certainly,
It can also be selected as other numerical value as needed.
In addition, respectively driving lesser two driven tooths of diameter by the driving gear 4 being relatively large in diameter in the embodiment
Wheel, to obtain sampling assemble 7 and beat the biggish reversal rate of component 9.
In the embodiment can multi-point sampling metallurgy with blast-melted sampling equipment when in use, complete primary sample can
With reference to following steps:
1, first by pedestal across the two sides of trough, and first support 11 and second support 12 is made to be located at molten iron
The two sides of ditch, and make the sampling equipment have the side of toothed disc 2 towards sampling operation personnel, while placing sampling and holding
Device, sampling container are located at the right side of the sampling equipment；
2, sampling operation personnel stand at a certain distance from trough, by inserting for shared crank 6 insertion driving gear 4
Enter in hole 42, and adjust the position in teeth area on driving gear 4, so that the initial end of teeth area in the counterclockwise direction and first
Driven gear 51 engages, and driving gear 4 is then rotated clockwise, so that driving gear 4 only drives 51 inverse time of the first driven gear
Simultaneously the bottom is to extreme position for needle overturning, to sample realizing in the overturning to trough of sample spoon 722 of sampling assemble 7；
3, complete sampling after, rotate counterclockwise driving gear 4 so that the first driven gear 51 drive sampling assemble 7 make it is suitable
Hour hands overturn to horizontal position and stay for some time, so that the molten iron in sample spoon 722 is cooled into sampling finished product；
4, after the molten iron in sample spoon 722 is cooled into sampling finished product, quick rotation driving gear 4 counterclockwise makes winner
Moving gear 4 drives the first driven gear 51 quickly to turn clockwise and the mounting rod 71 of sampling assemble 7 is made to hit and be connected in
On claw 10, so that the first time breakaway force for being detached from sample spoon 722 is provided for sampling finished product, at this point, the gear area of driving gear 4
It is detached from the first driven gear 51, the sampler 72 of sampling assemble 7 under inertia force effect, turn over towards the direction of sampling container by continuation
Turn lower button, so that second of breakaway force for being detached from sample spoon 722 is provided for sampling finished product, by providing secondary breakaway force, so that
The success rate that sampling finished product is detached from sample spoon 722 greatly improves, and accurately lower can finally detain to sampling container；
5, under the action of sampling twice breakaway force of the finished product in step 4, when still cannot successfully be detached from sample spoon 722,
It can will beat hammer 93 to release towards the direction of sampling assemble 7, then to the sample spoon for the sampling assemble 7 being connected on claw 10
722 are beaten, and specifically the process of beaing is, continue to rotate counterclockwise driving gear 4, until driving gear 4 and the second driven tooth
52 engagement of wheel, then, quick rotation driving gear 4 counterclockwise, so that driving gear 4 drives the second driven gear 52 along up time
Needle direction quick rotation turns clockwise so that beaing component 9, beats hammer 93 and beats sample spoon with higher rotation speed and dynamics
722, so that sample spoon 722 provides the third for being detached from sample spoon 722 for sampling finished product again towards detaining under the direction of sampling container
Secondary breakaway force, the number beaten can be selected as needed, until sampling finished product is detached from sampler 72.
In the application can multi-point sampling the blast-melted sampling equipment of metallurgy, deft design substantially increases sampling
The success rate of the crisp disengaging sample spoon 722 of finished product is sampled in device 72, and is accurately detained into sampling container down, thus
Substantially increase sampling efficiency.
When needing to be sampled the molten iron of different sample points, it can refer to following steps:
1, the sampling equipment is pushed then to lock universal wheel to the sample location of preset trough first；
2, extremely coaxial with transmission shaft 200 by 400 turns of driving head, and shared crank 6 is inserted into driving head 400, and will
Crank presses to limited post 201, so that the periphery wall block of driving head 400 and being limited on limited post 201, to pass through limited post
201 limit the movement of driving head 400；
3, it shakes and shares crank 6, so that driving head 400 drives driving gear 1011 to rotate through drive rod, in driven driving
Bracket slides up and down, until sampling assemble 7 is adjusted at preset height, in this way, to realize to sampling assemble 7 in trough
Depth selection adjusting.
The adjusting to the specific sample position of sampling assemble 7 is just completed by above-mentioned steps.In this way, can be as needed, it is more
The specific positioning to the direction along trough and the control to depth selection are realized in the sample position of secondary transformation molten iron, from
And realize multidraw.
In the application can multi-point sampling the blast-melted sampling equipment of metallurgy, can be as needed in trough
Molten iron carries out multidraw and increases the distribution of sampling point to improve the diversity of sampling.In this way, the sampling equipment is big
The confidence level for improving sampling and testing result greatly, provides reliable guarantee for subsequent assay.
