Belt conveyor head material multi-point sampling apparatus and sampling method thereof

Abstract

The invention relates to a belt conveyor head material multi-point sampling apparatus. The belt conveyor head material multi-point sampling apparatus comprises a pedestal platform, a sampling vehicleis subjected to transverse rolling and is arranged at the pedestal platform, a pulley is arranged at the sampling vehicle through a vertical driving unit, an overturn motor is fixedly arranged at a vertical rear part of the pulley, and drives a sampling shaft for rotation, a front end of the sampling shaft is fixedly connected with a sampling bucket, a tunnel is arranged below the sampling bucket,a blanking hose pipe is connected below the tunnel, and a transverse driving unit of the sampling vehicle, the vertical driving unit and the overturn motor are connected with a control system. The sampling method comprises the following steps: 1) resetting a system, 2) driving the sampling vehicle to move to a stop position; 3) driving the pulley to move to a lower part of a belt conveyor head; 4) driving the pulley back to an initial position, overturning a material with 180 DEG by the sampling shaft and introducing the material in the blanking hose pipe from the tunnel; 5) overturning the sampling shaft for 180 DEG; and 6) repeatedly carrying out the steps of 1-5. The sampling apparatus can guarantee the representativeness of the sample.

Description

technical field [0001] The invention relates to a sampling device and a sampling method, in particular to a multi-point sampling device and a sampling method for materials at the head of a belt conveyor. Background technique [0002] In power plants, coking plants and other occasions where a large amount of coal is used, the coal that enters the furnace is generally transported by a belt conveyor. In order to test the quality of the coal, it is necessary to install a coal sample sampling machine on the belt conveyor for sampling and testing. Existing sampling machines exist The following problem: the current belt head sampling machine is fixedly installed in the middle of the belt conveyor, because the position of the sampling machine in the belt width direction is fixed, so it only collects material samples within the corresponding belt range, and the sampled products are representative Not strong, the sampling results are easy to be manipulated by humans, and the purpose o...

Problems solved by technology

[0003] The object of the present invention is to provide a belt conveyor head multi-point sampling device installed on the belt conveyor head. This device is installed on the belt conveyor head, which effectively solves the problem that the traditional sampling machine takes up a lot of space, and adopts the head multi-point sampling method. , the sampling point can be set at random and multiple points, and the setting of the sampling point position is comprehensive, which can ensure the representativeness of the sampled products
