The invention discloses a sampling device for a belt conveyor. A small hopper bracket and a sampling bracket respectively cross at both sides of the belt conveyor; a sampling head and a storage hopper are installed on the sampling bracket; a small hopper is mounted on a small hopper bracket; the sampling bracket is installed at one side of the storage hopper and is close to the small hopper bracket; mechanisms fixed by the two brackets are located above the conveyor belt; a material lifting mechanism is arranged on the sampling bracket; a discharge port is located above the small hopper, and a feeding port is located in the storage hopper; a rotating shaft provided with the sampling head is in bridge joint to the sampling bracket; the bottom of the sampling head is fixedly connected with the rotating shaft, and the top of the sampling head is inserted into the materials in the belt conveyor; a main shaft of the sampling motor is connected with one end of the rotating shaft of the sampling head through a velometer; and the discharge port of the small hopper outlet is connected with a sample collection device. The sampling device provided by the invention conducts sampling along the flow of the materials, and cutting plane line at the top of the sampling head has high speed, so that the materials can obtain large initial kinetic energy to overcome the coal leakage. The storage hopper is in an arc structure, so that thrown materials fall into the storage hopper.
Description
technical field [0001] The invention relates to a material sampling device, in particular to a belt conveyor sampling device for material sampling of a belt conveyor. technical background [0002] In the fields of coal, iron ore and other minerals and energy sources, the purpose of sampling materials is to obtain a sample representing the entire cargo to determine various properties of the materials, such as calorific value, ash content, and sulfur content. Material sampling is an important part of material property analysis. To obtain accurate measurement data, representative samples must be collected. In domestic and international trade, the indicators of mechanized sampling samples are generally used as the basis for both parties to determine the price. [0003] With the continuous improvement of my country's machinery industry and the research on foreign mechanized sampling devices, a DJY-type scraper-type mechanical sampling device developed in my country has been wide...
