　　800mmBelt sampling machinestructure

　　Mining explosion-proof belt middle sampling machineIt is a sample equipment designed to extract bulk materials from conveyor belts. It consists of a sampling head, a driving device, a position detection device, and a steel structural component with a dust cover. The sampling head is made of stainless steel. And equipped with a balance block. Installed on a steel structure. It is driven by a motor through a reducer, which drives a fan-shaped cutter to rotate once. Scrape a complete cross-sectional sample with the same opening as the cutter from the moving belt, and send the sample through the chute to the next sample preparation system for crushing and reduction.

　　800mmBelt sampling machineAbnormal situations and malfunctions:

　　1. After connecting the power, the sampler keeps rotating or the sampling head stops on the belt: please check if the sensor is damaged. Under normal circumstances, when the reflector is turned in front of the sensor probe, the red light at the rear of the sensor should light up. The red light should not light up at all other times. If the red light stays on or does not light up, it indicates that the sensor is damaged.

　　2. After the sampler is turned on, there is no response from the arm shaft or the yellow light on the control box panel is on: please check if the sampling head is stuck and if the motor coil is normal

　　800mmBelt sampling machinesystem

　　1. Sampling time control system: In addition to the basic control circuit, it mainly consists of time relays. There are two sets of time on the time relay, each consisting of two digits and one time unit. The range of numerical adjustment is 0-999, and the time units are 0.1 seconds (0.1S), seconds (S), 0.1 minutes (0.1M), minutes (M), 0.1 hours (0.1H), and hours (H), respectively. For a single sampling time, adjust the range from 0.1 seconds to 999 hours and control the sampling time each time. To delay the startup time and the time between two samplings, adjust the range from 0.1 seconds to 999 hours, control the delayed startup time of the machine after startup, and also control the interval time between two samplings. The time for the sampling head to rotate once is about 1.46 seconds. Considering the positioning system, the rotation time should be set to 0.7 seconds, with an additional 1.46 seconds for each additional rotation. The sampling control system is controlled by the switch buttons on the panel and the central control interlock.

　　2800mm belt sampling machinePositioning system: Due to the circular motion of the sampling head, it may stop on top of the belt when stopped, causing wear and even damage to the belt and sampling head. The function of the positioning system is to prevent the sampling head from stopping on the belt. The system mainly consists of sensors installed in front of the gearbox, induction boards, and a set of relays inside the control box. The positioning system is not controlled by the switch buttons on the panel or the central control interlock. As long as the control box is powered on, the system starts working. Whenever the sampling head position is detected on the belt, the motor is automatically turned on, and the sampling head stops when it is turned outside the belt. During the sampling process, the positioning system is in a locked state and will not trigger. After the sampling time stops, the positioning system is automatically triggered.

　　3800mm belt sampling machineCentral control chain system; Mainly to receive start and stop signals from the central control room or main equipment, so that the machine can automatically start and stop accordingly. After switching to the central control interlock automatic start stop mode, the switch button on the panel automatically becomes invalid. When the central control interlock is in operation, if an emergency stop is required, please directly open the circuit breaker.
