Abstract
The utility model belongs to the technical field of the material sample, in particular to automatic sampling system of belt, including being used for carrying the one -level belt feeder to the factory in with the material from the pier, be provided with sampler on the one -level belt feeder, the through -put elephant trunk that takes out through sampler transports to the second grade belt feeder, is provided with the scraper blade reduction device on the second grade belt feeder, the scraper blade reduction device according to the division confirmed than accurate division, stay appearance to fall into the automatic loading head under the scraper blade reduction device. Through the elephant trunk transportation after the even sampling of the complete continuous intercepting of section of sampler, then carry out the division through the scraper blade reduction device, avoided the problem of material adhesion, also guaranteed material samples' representativeness, continuity and stability simultaneously.
Description
Technical field
The utility model belongs to material sampling technique field, particularly a kind of belt automatic sampling system.
Background technology
Traditional terminal belt sampling technique, mainly for the material that the viscosity such as bulk are little, has head and middle part sampling technique respectively, and have employed drum-type division method when division.The material that copper concentrate is little as a kind of granularity, water cut is higher, very easily adhere to, adopts traditional terminal belt sampling technique very easily to cause whole closed system internal bond, finally causes whole system to be paralysed, cannot use.In order to sample copper concentrate, existing way mainly contains two kinds, and one is hand sampling, and another kind is sampled by autonomous driving vehicle Sampling Machine.Hand sampling labour intensity is large, and autonomous driving vehicle Sampling Machine is because of the adhesion of material, and operational failure is many, and service efficiency is not high.
Utility model content
The purpose of this utility model is to provide a kind of belt automatic sampling system, can realize the automatic sampling of the stronger material of adhesiveness.
For realizing above object, the technical solution adopted in the utility model is: a kind of belt automatic sampling system, comprise the one-level belt feeder for being delivered to from harbour by material in factory, one-level belt feeder is provided with sampler, the material taken out through sampler is transported to second belt machine by elephant trunk, second belt machine is provided with scraper plate reduction device, scraper plate reduction device is by the accurate division of the division ratio determined, keep sample the automatic loading head fallen under scraper plate reduction device.
Compared with prior art, there is following technique effect in the utility model: sampler tunneling boring transports through elephant trunk after intercepting uniform sampling continuously, then division is carried out by scraper plate reduction device, avoid the problem of material adhesion, also ensure that material samples' representativeness, stability simultaneously.
Accompanying drawing explanation
Fig. 1 is principle schematic of the present utility model.
Embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail.
Consult Fig. 1, a kind of belt automatic sampling system, comprise the one-level belt feeder 10 for being delivered to from harbour by material in factory, one-level belt feeder 10 is provided with sampler 20, the material taken out through sampler 20 is transported to second belt machine 40 by elephant trunk 30, second belt machine 40 is provided with scraper plate reduction device 50, scraper plate reduction device 50 is by the accurate division of the division ratio determined, keep sample the automatic loading head 60 fallen under scraper plate reduction device 50, and abandoning sample generally can by other belt conveyor returning charge to one-level belt feeder 10 exports concentrate storehouse together to.By arranging elephant trunk 30, export on second belt machine 40 timely by the material that sampler 20 takes out, the drum-type reduction device commonly used in prior art is replaced to scraper plate reduction device 50, scraper plate reduction device 50 can carry out division to adhered materials effectively.The sampling head of sampler 20 is sampled rotational scraper, and about about 1cm bottom belt, injured belt when both can prevent belt from beating, and can ensure that again tunneling boring sampled.
This device can avoid the adhesion of material as far as possible, but can not absolutely avoid, and along with the accumulation of time, still has the possibility that blocking occurs.Therefore, whole system, under the prerequisite ensureing security protection, occupational health setting, adopts open by design as far as possible, is convenient to cleaning and safeguards.
Preferably, described elephant trunk 30 is more than or equal to 70 ° with the angle of horizontal direction, and the internal diameter of elephant trunk 30 is greater than the caliber of actual material requirement, and the corner of elephant trunk 30 is round-corner transition.The angle of elephant trunk 30 is larger, more can prevent material to stick together when sampler 20 is delivered to second belt machine 40 blocking; But angle is too vertical, be unfavorable for exporting on second belt machine 40 of material uniformly continous, and material is similar to freely falling body, excessive to the impact of second belt.304 stainless steels that elephant trunk 30 adopts 2mm thick make, and elephant trunk 30 is also provided with cleaning eye, pins sealing at ordinary times, open, conveniently disclose material when maintenance or putty.
Further, described one-level belt feeder 10 is provided with measuring belt scale 70 for gathering the weight of convey materials on one-level belt feeder 10, measuring belt scale 70 output weight information is to host computer or controller 80, and host computer or controller 80 control sampler 20 sampling according to the weight information received only is sampled with opening.By arranging measuring belt scale 70, weight of material on one-level belt feeder 10 can be measured, and control sampler 20 according to metric results and sample, such as according to demand, be an inspection batch with every 65 tons of copper concentrates, each inspection lot sub-sampling ten five to two ten times, so measuring belt scale 70 often claims 65 tons of copper concentrates to pass through, host computer or controller 80 just output control signals to sampler 20, and sampler 20 adjusts sampling frequency automatically according to loading frequency.By measuring belt scale 70, host computer or controller 80, achieve automatic sampling on one-level belt feeder 10, reduce human cost.
Further preferably, described sampler 20 is provided with material detecting unit 21, material detecting unit 21 for detect whether one-level belt feeder 10 have moving material through and control the start and stop of sampler 20 according to testing result, be adopt in order to sampler 20 when preventing one-level belt feeder 10 not having material carries out sky like this.
As preferred version of the present invention, described host computer or controller 80 output control signals to scraper plate reduction device 50 for controlling the division ratio of scraper plate reduction device 50.After arranging like this, can improve the robotization of system further, the holding barrel except automatic loading head 60 li needs artificial replacing, and whole sampling process completes substantially all automatically, convenient and swift.
