Abstract

The invention provides a coal sample gathering device and a gathering method, so as to solve the present problem of low gathering efficiency when gathering different varieties of coal samples. According to the gathering device, the bottom of a fixing frame is fixed with a motor and a conical tooth transmission device, which is connected with the bottom of a main shaft; the main shaft is fixed with an upper rotating disk and a lower rotating disk; a collecting basket is disposed on the lower rotating disk; the corresponding position on the upper rotating disk is provided with a hole which fits with the collecting basket; a feed hopper is connected to the top of the fixing frame; and a level sensing device is connected inside the feed hopper. According to the invention, the motor can drive the conical tooth transmission device to drive the main shaft to rotate, and the main shaft is fixed with the upper and lower rotating disks, therefore, the rotation of the upper and the lower rotating disks can drive the collecting basket on the lower rotating disk to rotate. When the collecting basket rotates under the feed hole of the feed hopper, automatic gathering of the coal sample can be accomplished, thus raising the automation degree of coal sample gathering and helping improve the efficiency of coal sample detection and examination.

Description

technical field [0001] The invention relates to the technical field of coal sample preparation equipment manufacturing, in particular to a coal sample collection device and a collection method. Background technique [0002] With the improvement of industrial automation, the automation efficiency of machines has also been continuously improved. If the efficiency of the supporting feeding, or discharging, or collecting device cannot keep up, it will affect the automation level of the entire mechanical system. [0003] For example, when the coal sample is crushed and divided by the sample maker, it needs to be collected before the collected coal sample can be inspected and tested. And when coal samples are inspected and detected, it is often necessary to inspect and detect coal samples of different varieties and coal samples from different mining areas. Therefore, it is necessary to use different collection barrels to collect different coal samples that have been crushed and ...
