Limestone belt sampling machine belt head sampling machine belt automatic sampler

Mid-belt sampler is a device designed to take samples of bulk material from the conveyor belt. It is composed of a sampling head, a drive device, a position detection device and a steel structure with a dust cover. The sampling head is composed of stainless steel. And is equipped with a balance block. Mounted on the steel structure.

-\\Performance characteristics of sampler in the middle of belt:

1 The main technical component of the system is the sampling device. The sampling head is made of stainless steel, and the lower end of the sampling head is equipped with a scraping plate which is in soft contact with the coal conveying belt. The rotating arc of the scraping bucket is basically consistent with the radian of the belt carrying coal. It can not only damage the coal conveying belt, but also scrape the entire section of the coal flow and take out the sub-sample completely

2, the sampling head adopts the mechanical and electrical measures to prevent the sampling head from staying and falling into the coal flow, so as to ensure that the sampling machine does not affect the normal operation of the coal transport operation, and the incoming material detection device is set up, and there will be no empty mining phenomenon.

3\\ The whole machine is composed of programmable controller (IPC) + text display (TD400) to realize manual/automatic control

4\\ The system is equipped with incoming material detection device.

5\\ Sampling time can be set upon request.

Two belt middle sampler working principle:

The sampling head is driven by a motor with braking function controlled by a timer, which cuts into the material flow at a constant speed. During the movement of sweeping through the belt conveyor, a complete sub-sample of the whole section is taken. The sub-sample scraped is thrown into the collecting tube, and enters the primary sample feeder through the chute. When the sampling machine rotates - circle to exit the material, the proximity switch senses and sends a control signal, the brake motor brakes, the sampling head stops rotating, and the time relay starts timing, Until the next sampling period, start the motor again for sampling at regular intervals. The sampling period is preset and adjusted by the PLC control system. The sampling head rotation protection ensures that only one turn can be made at a time. The overload protection reverses when the sampling head is overloaded, and finally stops at the stop position. The double proximity switch ensures the reliable operation of the system, and the fault protection ensures that the sampling head will not stop at the middle of the belt

Three belt middle sampler work flow:

1\\ Start the sampling machine according to the set time;

2\\ The sampling head rotates through the material flow and intercepts the material horizontally until the proximity switch is triggered; At the same time, the material falls into the chute;

3\\ After the proximity switch is triggered, the motor is cut off and the brake is applied. Stop the sampling head and keep it at the opposite position of the material flow (zero position);

4\\ Timer timer enters the down-cycle.

Belt sampler is a kind of fast, simple, reliable and economical sampling equipment which can directly collect materials from the conveyor belt in motion. It can be used as a single platform sampler or a primary sampler in a multistage sampling system. It is used in power plant, coal mine, steel mill and other industries to realize automatic random sampling on the seat surface to eliminate the interference of human factors.
