Further, a belt flow material autosampler, the sampling tube (7) further comprises: and the tip (75) and the hinge (76) are arranged at one end close to the tip (75), after sampling, when the tip (75) moves to the position of the sampling cylinder hoop (71), the lower parts of the first half cylinder (72) and the second half cylinder (73) are opened under the action of the elastic hinge (77) due to no squeezing, and the sampled material enters the discharge opening (4).
Further, a belt flows material autosampler, the bottom of feed opening (4) is the toper and guides the material and gets into F material elephant trunk (5), gets into sample bucket (6) from F material elephant trunk (5).
Further, according to the automatic sampler for the belt flow materials, a movable baffle is arranged at the sampling port (81), and the sampling port (81) is covered after sampling.
Further, according to the automatic belt flow material sampler, the sampling frequency of the cylinder (2) for controlling the sampling cylinder (7) is adjusted through a time relay or a central control DCS control program.
The invention has the advantages that: the belt conveyor belt sampling device can uniformly, quantitatively and regularly sample, reduce sampling deviation caused by human factors and the condition that raw coal is not uniformly loaded in the sampling process, can maximally and truly reflect the quality condition of materials entering a factory, fairly and positively reflect the product quality, and reduce the acceptance risk.

Detailed Description
The present invention will be further described with reference to the accompanying drawings so as to facilitate the understanding of the present invention by those skilled in the art.
As shown in fig. 1 ~, an automatic sampler for belt flow materials comprises an installation base plate (1), a cylinder (2), a gas rod (3), a feeding port (4), an F-shaped material chute (5), a sample barrel (6) and a sampling barrel (7), wherein the cylinder (2) is installed on the installation base plate (1), the gas rod (3) at the front end of the cylinder (2) extends into the upper part of the feeding port (4), the bottom of the feeding port (4) is conical to guide materials to enter the F-shaped material chute (5), the materials enter the sample barrel (6) from the F-shaped material chute (5), the gas rod (3) is connected with the sampling barrel (7) to push the sampling barrel (7) to sample the belt flow materials through a sampling port (81) on a belt (8), the gas rod (3) is contracted after sampling, the sampling barrel (7) is pulled into the feeding port (4), the sampling barrel (7) is opened to sample the sampling barrel (6) through the feeding port (4) and the F-shaped material chute (5), the sampling barrel (6) and the sampling port (7) is opened, the sampling barrel (7) enters the sampling barrel (7) through the feeding port (4) and the second sampling port (71), the second sampling barrel (73), the second sampling barrel (71) is hinged to the second sampling barrel (73), the second sampling barrel (73) is hinged to cover the second sampling port (73), the second sampling barrel (7), the second sampling barrel (73), the second sampling port (73) and the second sampling barrel (73), the second sampling barrel (7) are opened, the second sampling barrel (7) and the second sampling barrel (7) are opened, the second sampling barrel (7) and the second sampling barrel (7) are positioned in the second sampling barrel (7), the second sampling port (7) after the second sampling port (7) and the second sampling port (7) after the second sampling barrel (73), the.
