Accompanying drawing 6 schematically provides the process that coal sampling and preparing machine of the present invention carries out coal samling of using, move to as shown in Figure 6 the fortune coal coal bin of coal sample to be collected by control system control sampling prototype, then finish the work such as sampling-sample presentation-sample preparation (fragmentation, division, collection sample)-abandon sample according to the following process of controlling.
The full-automatic coal sampling prototype of vehicle-mounted removable of the present invention need make motor car engine power takeoff and hydraulic plunger variable, pump quantitative gear pump make its engagement by transfer gear control before operation.Gathering and processing the coal sample process is full automatic working, and the specific works process is as follows:
Sampling prototype open beamhouse operation: at first by automobile the coal sampling and preparing machine is moved near the dump to be sampled (or coal car/coal bin), then front hydraulic leg 4 and the rear hydraulic leg 8 installed on the automobile chassis 1 are opened, and by adjusting so that front and back hydraulic leg along continuous straight runs and vertical direction reach ground and support firm.Then computer program sends sampling apparatus 7 and opens order in the vehicle-mounted OPS, big arm cylinder 12 in the sampling apparatus 7 makes large arm 11 rise to certain position; oil cylinder of small arm 13 motionless (at this moment oil cylinder of small arm 13 is that the top is to the longest position); simultaneous retractable arm 15 reaches certain position; pivot angle oil cylinder 17 is failure to actuate; then sampling apparatus 7 rotates to the anglec of rotation of working position by base 10, and sampling head is arrived near any one working position in 6 working positions selecting at random.
Sampling prototype gather and process the sample operating process:
Computer program sends the bicycle sample command, and bicycle sampling refers to that sampling apparatus finishes the one bout action namely: choose adopt a little → sample → promote that sampling head → revolution sample presentation → sample preparation → next adopts point sampling to be turned back to working position → continuation.Stay wire sensor all is housed on the oil cylinder of sampling apparatus 7, is equipped with on the pivoting support of base 10 on rotary encoder, the sampling head 19 obliquity sensor is housed.These sensors all can be accurately for the control of moving provides data, and the PLC processor sends corresponding action command by analyzing these data.Concrete action refers to: sampling apparatus 7 is after working position is received the sampling instruction:
(1) forearm 14, telescopic arm 15, base 10 move simultaneously and arrive certain sampling point position (piling the 300mm height apart from the matchmaker), and pivot angle oil cylinder 17 discontinuity move to adjust sampling head 19 in this process, lock after sampling head 19 is adjusted angle;
(2) forearm 14, telescopic arm 15, pivot angle oil cylinder 17 move simultaneously, guarantee that sampling head 19 begins downward or oblique lower the sampling with same not varied angle, and the coal sample of collection is just transferring upwards to be delivered to storage bin by rotation helical blade in the sampling head;
(3) after sampling head 19 is adopted designated depth; forearm 14, telescopic arm 15 move simultaneously; sampling head 19 is upwards risen to apart from dump predetermined altitude (300mm) by even acceleration; sampling head continues forward until arrive above materials device processed in this process; and sampling head is unlocked, and is in free operating state;
(4) base 10, telescopic arm 15 move simultaneously and are turned back to certain angle to sample preparation device 3 feeder hoppers 20 even acceleration, then stop, and this process sampling head is in free state;
(5) then forearm 14 and telescopic arm 15 move when making sampling head storage bin bin gate drop to apart from sample preparation device feeder hopper 20 certain altitude simultaneously, again turn round respective angles, the storage bin bin gate of sampling head is turned to directly over the sample preparation device feeder hopper 20,33 actions of bin gate oil cylinder are opened the storage bin bin gate, coal sample to be collected is closed bin gate after falling into sample preparation device, and sampling head 19 keeps locking state in this process;
(6) sampling head 19 releases make it be in free state, and oil cylinder of small arm 13 actions are upwards spared sampling head 19 and accelerated to rise to former working position height;
(7) begin to select at random another sampled point to this dot system, base 10 revolution accelerates to new sampled point angle, and then forearm 14, telescopic arm 15 and pivot angle oil cylinder 17 moves simultaneously and make sampling head 19 carry out next circulating sampling above adjusting to this sampled point.
In the said process of bicycle sampling, preferred big arm cylinder 12 remains that the position of adjusting is failure to actuate, and refer to that in " forearm 14 actions " described in the said process it moves with respect to large arm 11 under the effect of oil cylinder of small arm 13, described " telescopic arm 15 actions " refer to that it is stretching under effect of telescopic boom cylinder 16 in forearm 14, described " base 10 actions " refer to that it horizontally rotates under the effect of swing bearing, described " 17 actions of pivot angle oil cylinder " refer to that it drives four-bar mechanism 18 motions by hydraulic jack.
When bicycle sampling revolution, computer program also can send the sample preparation instruction simultaneously.That is: the broken coal sample of breaker 21 work → division device 23 work are carried out division → collection sampling device work to coal sample and are collected coal sample (automaticallying switch after collection sample bucket 28 is full, next collects sample buckets 28).When sampling apparatus 7 beginnings are turned round to sample preparation device 3, crusher motor starts, make breaker 21 work, then division motor 27 starts division device 23, coal sample after the fragmentation is slipped by rejected material chute 24 by division device 23 parts and is entered to abandon sample case 2, and a part is slipped by the chute 25 that gathers materials and entered to collect sample bucket 28.After aggregate tube is full, ultrasonic sensor obtains signal and is delivered to system, program is given an order to direct current generator 32 after judging, make it drive bevel pinion 31, bevel pinion drives large helical gear 30, and large helical gear 30 drives collection sample pallet 29 and rotates, on the pallet 29 travel switch is housed, when collection sample bucket 28 vertical alignments gathered materials the discharging opening of chute 25, travel switch obtained signal, and direct current generator is stopped.Automatic switchover dual mode after the collection sampling device also can support operating personnel manually to select bucket position and material to expire.After sample preparation was finished, sample preparation device quit work.
Sampling prototype recovery operation: after sampling, sample preparation, collection sample finish, the operating computer program is sent jib and is regained instruction, that is: make sampling head be in free state, rotary table 10 makes sampling apparatus 7 be turned back to zero-bit, then telescopic arm 15 is retracted into zero-bit; forearm 14 supports are to dominant bit, and then large arm 11 nutations are located on the bracing frame.The front and back hydraulic leg is regained, and so far automobile chassis 1 can sail out of the work place.
Below only be that preferred implementation of the present invention is described; technical scheme of the present invention is not limited to this; the any known distortion that those skilled in the art do on the basis of major technique of the present invention design all belongs to the claimed technology category of the present invention, and the concrete protection domain of the present invention is as the criterion with the record of claims.
