Feeding machine
Technical Field
The utility model belongs to coal, small granular or powdery solid material sample feeding equipment, concretely relates to batcher.
Background
At present, when a sample of coal, small granular or powdery solid materials is collected in a carriage of an automobile or a train, a full-section spiral sampling head is often adopted. In order to improve the working efficiency, after three points are continuously collected, the sampling head returns to the sample unloading position to be discharged once, because the sample amount collected at each point is large, the sample amount remained at each collected point is about 40-60kg generally, the total sample amount remained at three points is continuously collected is about 120-180kg, the collected sample remained is directly discharged to the feeding adhesive tape machine, and the feeding adhesive tape machine conveys the sample remained to the sample preparation system for sample preparation. This process has the following problems: the method has the advantages that when the moisture content of a sample is high or the viscosity of the sample is high, the sample is easily stuck and blocked at a feeding port of a feeding rubber belt conveyor, so that the sample is mixed up, and the blocking of the feeding port is caused in serious cases; two sides of a feeding port of the feeding adhesive tape machine are easy to generate side leakage due to accumulation; and thirdly, due to the fact that the material inlet is accumulated, the sample preparation system is easy to cause faults such as blockage and overload tripping of a motor caused by overlarge instantaneous sample flow, and the normal operation of sample preparation and sample representativeness are seriously influenced.
