Product name: HC train sampling device

HC train sampling equipment is divided into bridge type, door type, cantilever type three kinds of sampling system, according to the specific situation of the site to choose. The system is a kind of special equipment which is installed beside the railway line of coal loading in a coal mine, and takes coal samples from the railway cars loaded with coal according to relevant standards, and makes the coal samples for physical and chemical analysis with a certain particle size. Under the control of the preset program, automatic operation is realized.

The bridge type and door type sampling equipment belongs to the movable type. The train box containing materials can be moved by the sampling equipment instead of running. Sampling and sample preparation can be carried out while moving.

Scope of application:

HC type auger sampler refers to the train, car carriage, barge cabin and open - air material pile. Sampling method of sample collection. The system is applicable to power, metallurgy, coal, port and other industries.

System composition:

A typical auger sampling system consists of two stages of sampling equipment, including oil motor, spiral sampling head, sampling cantilever, rotating mechanism, up and down travel mechanism; The sample preparation system consists of coal sample hopper, crusher, separator, sample collector and waste material processing equipment.

System working process:

The working process of the system is as follows: the train sampling device system is arranged in a width of about 2.8m between the two coaling trains. System is mainly composed of servo control system, sampling, sample preparation system, back to the abandoned coal conveying system and the PLC program control system of the machine, when start sampling, system boot, sample preparation system began to work, first by the operator to determine the required sample point and automatic or manual sampling signal is given, then the starting of the hydraulic pressure station, after being stable working pressure, command and control system of hydraulic cantilever scaling and rotation of slewing mechanism make the sampling head in place, then sampling head downward to start sampling, servo system start to work at this time, make the level of the entire process of sampling sampling head movement speed and speed of movement of the coal train basic consistent, Sampling of coal sample was taken first to 1/2 of the shrink points in the process of sampling, coal to return to the original car, the samples of coal in the sampling head set inside the hopper, and then the sampling head line, command and control system of hydraulic cantilever scaling and rotation of slewing mechanism make the sampling head aggregate bin arrived in sample preparation system and send samples to the sample preparation, sample preparation system collects the sample into the crusher, crushing after splitting device for splitting, sample into the collector, excess stock return train through the concrete system.

System features:

◇With automatic reset protection function

◇ continuity and integrity of sampling

◇Samples can be sampled in any direction

◇There is an alloy drill under the sampling head, which can break large pieces of coal, freeze coal seams and push away foreign bodies;

◇Screw feeder and crusher, to ensure the sealing effect, no leakage of dust

◇The crusher can adjust the crushing precision by adjusting the position of the ring hammer, the direction of rotation or the grate net;

◇The crusher is equipped with side sealing plate to facilitate cleaning and maintenance;

◇The divider is a square structure, built-in rotary cutter, the overall sealing, anti-blocking design, the fraction ratio can be adjusted according to the needs of arbitrary;

◇The system has rich configuration and control screen, can store relevant historical data, with the data printing report function.

Equipment performance:

◇The sampling head is controlled by the hydraulic system. When the sampling head encounters large stones, wood blocks, metal debris, etc. and becomes stuck or the speed drops, the stall protection device will send out a signal, and the helical reversal will remove foreign bodies or the overflow valve of the hydraulic system will unload automatically with automatic reset protection function.

◇The oil motor of the sampling head and the helical stringer are connected by a coupling to ensure the continuity and integrity of the sampling. There is an alloy drill under the spiral hinged cage of the sampling head, which can break large pieces of coal, freeze coal seams and push away foreign matters, ensuring the normal operation of the sampling head.

◇ Through the upper computer, hydraulic control; The control of hydraulic system cancels manual control and can realize automatic control. The hydraulic system adopts variable pump, which can adjust the flow automatically through proportional control valve according to the working state of sampling head and hydraulic arm.

◇The crusher can adjust the discharging quantity and particle size by adjusting the position of the ring hammer or changing the aperture of the sieve plate; The crusher is equipped with the cast-iron chamber to avoid the damage of metal debris or other hard pieces; The crusher is equipped with side sealing plate to facilitate cleaning and maintenance. The reducer is designed for overall sealing and anti-clogging, the opening size of rotary cutting edge can be adjusted and the speed can be adjusted, and the shrinkage ratio can be adjusted arbitrarily according to the need.

◇The PLC control part of the system adopts products of MODICON or SIEMENS or AB, which can communicate with the field network interface conveniently. The system has rich configuration and control screen, can store relevant historical data, has the function of data printing report form. The system adopts the overall structure design, can quickly and accurately complete the sampling process automatically; The sampling head can be located arbitrarily in three-dimensional space, reducing the influence of human factors and environmental factors. It also provides a convenient manual sampling platform.
