Contact.
7. according to claim 1 can continuous sample introduction type full-automatic caking index analyzer it is characterised in that: described rotary drum
(1) the sample position that goes out below is provided with and unloads sample groove (1-4)；Described unload sample groove (1-4) be arranged right below funnel (8)；Described base
(5) it is provided with pallet (9) below, just to the position of funnel (8).
8. according to claim 1 a kind of can continuous sample introduction type full-automatic caking index analyzer using method, it is special
Levy and be, comprise the steps:
1), startup self-detection；
2), after the completion of, treating self-inspection, coal sample is put into one by one in the sample container (6-2) of reference numeral, equipment is started working；
3), the sliding door (1-1) of rotary drum (1) upward and opens the sliding door (1-1) of rotary drum (1), by coal in No. 1 sample container (6-2)
Sample is poured in rotary drum (1), now the upper article heavy burden difference of recording balance (2), and that is, the gross weight of 8 coal samples deducts remaining 7 coal samples
Gross weight difference, original gross weight m of as No. 1 coal sample, feed back to pc, this is to weigh for the first time；While weighing, rotary drum (1)
Sliding door (1-1) close and start to rotate 5 minutes 250 circles, and automatically pick sampling device (7) and start working, will run to turning
In place below drum (1)；
4), after 250 circles, the sliding door (1-1) of rotary drum (1) down and is opened, and coal sample falls into via the funnel (8) below rotary drum (1)
In the early manned screening container (7-1-2) automatically picking sampling device (7), and the particle that diameter is less than 1mm is fallen in automatic fitration,
5), automatically pick sampling device (7) to return above rotary drum (1), No. 1 coal sample is sent in No. 1 sample container (6-2), balance
(2) weigh for the second time, pc recording quality m1；
6), equipment is repeated in the process of above-mentioned steps 3, step 4 and step 5 once automatically, and balance (2) is weighed for the third time, pc
Recording quality m2；
7), the waste sample of No. 1 coal sample is poured into and unload sample groove (1-4), complete the mensure of No. 1 coal sample caking index g value, result is by pc end
Immediately arrive at and store record；
8) after, completing once to measure, controlled by software and continue to be automatically performed the mensure of other coal sample g values, until drawing whole g
Value.
