Fig. 1 is point structural representation for ore deposit system that keeps sample of the embodiment of the present invention;
Fig. 2 is the structural representation of sample barrel.
Embodiment
Below in conjunction with accompanying drawing of the present invention, be clearly and completely described technical scheme of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention proposes one such as Fig. 1 and comprises chassis 3-11, sample barrel 3-10, pull bar 3-7, pull bar motor 3-3, suction cleaner 3-4, pneumatic pump 3-1, upper cover 3-2, unmanned position read write line 3-9, manual mode read write line 3-6, rotary electric machine and control module 3-8 and sample barrel label 3-5, sample barrel 3-10 deposits the coal sample of different supplier within the different time periods, the coal sample of supplier can be received simultaneously, and there is 3-10 in different sample barrels.
As shown in Figure 1, chassis includes existing proximity switch or photoelectric sensor and rotary electric machine, all sample barrel 3-10 are weldingly fixed on the 3-11 of chassis uniformly, sample barrel has n, n >=1, each sample barrel bottom is sealed by pull bar, and pull bar 3-7 is electrically connected with pull bar motor 3-3, and is controlled by control module 3-8.
As shown in Figure 2, sample barrel 2-1 up-small and down-big (namely as shown in Figure 2, top radius L less of bottom radius), stainless steel material makes, and prevents coal sample from sticking on the inwall of sample barrel.Each sample barrel is provided with a close distance radio frequency label 2-2 along chassis radial outside, the inside with each sample barrel code, and stored in control module database.
The sample barrel position that unmanned position read write line 3-9 is just right, is unmanned pattern sample position, is connected, can realizes full-automatic encapsulation with automatic packaging unit; The sample barrel position that manual mode read write line 3-6 is just right is artificial pattern sample position, and this position is the position receiving division coal sample from sampling unit simultaneously.Above unmanned pattern sample position, shared upper cover 3-2 is installed, and is connected with pneumatic pump 3-1; Below unmanned pattern sample position, suction cleaner is installed, with the coal sample dust produced when working with absorption pneumatic pump.
Control module 3-8 provides manual sampled functions, if unmanned sampling mode breaks down, after ALM, operating personnel press the manual sample button of control module, sampled sample barrel can rotate to manual mode read write line 3-6 position, personnel press hand push button, and pull bar sealing is pulled open, and manually connects sample.
After coal sample is removed, control module 3-8 feeds back to sampling unit and samples complete signal, sampling unit can continue sampling, and control module 3-8 automatically generates, is recorded into database and prints sampling coding simultaneously, is attached on the coal sample bag be removed by artificial or mechanical arm.
The present invention realizes intelligent management, and its control method comprises the following steps:
Step 1 automatic rotation: control module 3-8 monitors sampling unit, determine whether the coal sample needing to keep sample, if there is the coal sample needing to keep sample, read the relevant information (supplier, transport column etc.) of coal sample, start rotary electric machine and carry out swivel base 3-11, rely on proximity switch technology or photoelectric sensor technology, select the coal sample container 3-10 needed.After rotary electric machine has rotated by information back to control module 3-8, control module sends instruction and to stop the rotation work.
Step 2 automatic Verification: control module 3-8 starts frequency read/write 3-6, scan and identify just to the electronic tag 3-5 of sample barrel 3-10, and the label 3-5 comparison of this sample barrel 3-10 with control module 3-8 lane database, if correct, enter further work; Otherwise automatic rotation chassis 3-11, sends alarm signal again simultaneously.After sample barrel 3-10 positive stop, control module 3-8 closes frequency read/write 3-6, and start up system self-checking alarming function.
Step 3 keeps sample automatically: after sample barrel 3-10 puts in place, and control module 3-8 is to sampling unit signal, and start to receive the coal sample that sampling unit gets off, after sampling unit blowing terminates, to control module 3-8 instruction, setting-out terminates, and control module stops the work that keeps sample.
Step 4 samples self-inspection: control module 3-8 detects sampling unit, determines whether the coal sample needing sampling.The coal sample sampled if necessary, control module starts self-checking function, checks whether the full-automatic sampled functions of self can normally work, and monitors the working signal of encapsulation unit, if normal, enters the mode of operation of unmanned sampling; If full-automatic sampled functions has fault or can not get encapsulation unit signal, then enter the mode of operation of hand sampling, and send alarm signal.Self-inspection terminates to feed back to control module 3-8, and control module 3-8 sends instruction and stops self-inspection.
Step 5 automatic sampling: control module 3-8 starts rotary electric machine, swivel base 3-11 is the position needing the sample barrel 3-10 of sampling to rotate to unmanned frequency read/write 3-9 place, open frequency read/write 3-9, check sample barrel 3-10, if correct control module 3-8 starts rotary electric machine, open pull bar motor 3-3, mobile sample barrel sealing, coal sample flows into encapsulation unit material receiving port automatically.Otherwise continue to rotate.Three rotations are checked all incorrect, then enter hand sample pattern.
Step 6 automated cleaning: after sampling receives, control module 3-8 starts the public upper cover 3-2 of sample barrel and declines, and covers sample barrel 3-10 suitable for reading; Then start pneumatic pump 3-1 and discharge pressurized air, start the suction cleaner 3-4 being arranged on sample barrel end opening simultaneously, draw residual coal dust flue dust.After having cleaned, relevant information is returned to control module 3-8, control module 3-8 sends instruction, and stop cleaning, upper cover 3-2 moves, and pneumatic pump 3-1, suction cleaner 3-4 close.
Step 7 generates, print and read the bar code information of sample, and by information stored in central database, process completes.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should described be as the criterion with the protection domain of claim.
