Description
Technical field
The utility model relates to sampler fields, and in particular to a kind of belt middle sampler.
Background technique
Belt automatic sampler is during the gathering and processing of coal sample, and taking for coal sample is important link in gathering and processing,
Whether coal sample is representative, and taking for coal sample is crucial.It when manual sampling, is often influenced by sampling instrument, human factor etc., institute
Coal sampling representativeness is not very by force, to replace manual sampling with automatic sampler, fully meet national standard.The sampling dress in sampling
It sets and does tunneling boring from belt according to set time and sweep, the increment taken enters crusher by chute and crushes, and increment passes through
Secondary belt divider, which is divided into, to keep sample and rejected material, keeps sample and is automatically collected in storage tank, abandoning section is returned to by bucket elevator
Belt.Belt conveyor mainly has horizontal and both ends to be folded upward at two kinds of forms at present, and chute is fixed on body side, in reality
Border operation in, sampler to coal stream carry out tunneling boring sweep, due to the relative position of sampler and chute be it is fixed, two
Person's spacing, angle cannot change, therefore position can not match with belt position both when being mounted on belt, lead to one
Coal charge is divided to be swept to chute, it is also necessary to carry out manual cleaning, the method for solving problems at present is replacement sampler
Model leads to higher cost.
Utility model content
In order to overcome the above technical problems, the utility model provides a kind of belt middle sampler, is able to solve coal sample
It is easy to be swept problem to chute.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of belt middle sampler, including
Belt support frame, belt, samples machine support, rack and sampler at belt roller, installs multiple skins being equally spaced on belt support frame
With carrying roller, the belt that the installation left and right sides is folded upward on belt roller, belt support frame middle part installation samples machine support, sampler
Installation frame on bracket installs sampler in rack；The control cabinet of sampler is installed above rack and is connect with control cabinet
Alternating current generator, sampling scraper and chute are installed in the left and right sides respectively below rack；Opening of the chute close to belt one end
Two sides connect the sliding slot of connecting rod bottom by U-shaped board, and connecting rod top connects rack.
As the further improvement of this programme, the chute is infundibulate, and opening of the chute close to one end of belt is greater than
Its opening far from belt one end, chute are sequentially connected external crusher and contracting device far from the opening of belt one end；Not
In the case where influencing total quality and operating condition, the feed inlet of chute is increased, to reduce coal charge leakage.
As the further improvement of this programme, the chute is designed with more in the opening two sides of belt one end, U-shaped board
A mutually matched screw hole is all bolted between chute and U-shaped board, between U-shaped board and connecting rod；Different model can be directed to
Belt, by connecting rod, U-shaped board adjust chute position and angle, make chute opening it is parallel with belt edge flexure plane, effectively
It reduces coal charge and is swept the phenomenon outside chute.
As the further improvement of this programme, sampling scraper head end is equipped with polyurethane sheet, it is ensured that can completely scrape coal
The tunneling boring of stream, and belt will not be damaged.
The utility model has the beneficial effects that belt middle sampler optimizes overall structure, the position of chute
It can be adjusted according to belt position with angle, so that the feed inlet of chute is close to belt edge and parallel with it, increase
The scraping of coal charge effectively reduces coal charge into amount and is swept the phenomenon outside chute.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of rack.
Fig. 3 is the enlarged diagram of A in Fig. 1.
Fig. 4 is the electrical schematic diagram of the utility model.
It is indicated in figure, 1. belt support frames, 2. belt rollers, 3. belts, 4. sampling machine supports, 5. racks, 6. samplers,
601. control cabinets, 602. alternating current generators, 603. sampling scrapers, 604. chutes, 7.U template, 8. connecting rods.
Specific embodiment
Referring to Fig.1-3, a kind of belt middle sampler, including belt support frame 1, belt roller 2, belt 3, sampler branch
Frame 4, rack 5 and sampler 6 are installed multiple belt rollers 2 being equally spaced with bolt on belt support frame 1, are pacified on belt roller 2
The belt 3 that the dress left and right sides is folded upward at, 1 middle part of belt support frame install sampling machine support 4 with bolt, sample and use on machine support 4
Bolt installation frame 5 installs sampler 6 in rack 5；The control cabinet 601 of the top of rack 5 bolt installation sampler 6 and with
The alternating current generator 602 that cabinet 601 connects is controlled, sampling scraper 603 and chute 604 are installed in the 5 lower section left and right sides of rack respectively；Institute
It states chute 604 and passes through the sliding slot that U-shaped board 7 connects 8 bottom of connecting rod, 8 top bolt of connecting rod close to the opening two sides of belt one end
Connect rack；The chute 604 is infundibulate, and opening of the chute 604 close to one end of belt 3 is greater than it far from 3 one end of belt
Opening, chute 604 is sequentially connected external crusher and contracting device (being not drawn into figure) far from the opening of 3 one end of belt；It opens
Dynamic alternating current generator 602 provides power, and control cabinet 601 controls sampling scraper 603 and presses the scheduled sampling period, from the belt of operation
It is cut transversely on 3 with certain speed and inswept coal stream, intercepts complete increment on a cross sections, which is thrown into chute
604, feed inlet is increased using the chute 604 of funnel structure, to reduce the outer leakage quantity of coal charge.
By Experimental comparison discovery when chute feed inlet close to belt and it is parallel with its bending edge when, sweep outside chute
The coal charge in portion is minimum, therefore can be designed in the opening two sides of 3 one end of belt, U-shaped board 7 in chute 604 multiple mutual
The screw hole of cooperation is all cooperatively connected by bolt between chute 604 and U-shaped board 7, between U-shaped board 7 and connecting rod 8, makes chute 604
Feed inlet abuts belt 3 and setting parallel with it.
Since each scraper of sampling scraper all can fix a strata ammonia in 603 head end of sampling scraper with belt friction
Ester plate, it is ensured that can completely scrape the tunneling boring of coal stream and damage belt.
Referring to Fig. 4, sampler electric control system selects PLC, and there are the spare points of 10% I/O signal, and can be by system master
The status signal of equipment and important warning message are sent to coal handing system, and the distant place control for receiving defeated coal stored program controlled refers to
It enables.The system uses two kinds of control modes: remote auto control (can link with main belt) manually boots and (is mainly used for single machine
Debugging, plant maintenance), wherein manual mode priority is higher than automated manner.It is interlocked with main belt, when main belt is stopped transport (including
Failure is stopped transport), Sampling Machine hard stop (if acting, is shut down, guarantee that sampling head stops in place) after movement, remaining
Equipment then sequentially shut down by delay, guarantees the not stagnant material of internal system.
