Grain sampler

Abstract

The invention relates to a grain sampler. The grain sampler comprises a cantilever frame arranged at the upper end of a stand column and extending horizontally, and a rotating mechanism is arranged between the cantilever frame and the stand column; a moving frame is arranged on the cantilever frame and moves in the length direction of the cantilever frame in a reciprocating mode, a first guiding and conveying unit and a second guiding and conveying unit are arranged on the moving frame, a clamping opening for clamping a sampling tube is formed in the region between a conveying belt of the first guiding and conveying unit and a conveying belt of the second guiding and conveying unit, and a power mechanism drives a driving gear of the first guiding and conveying unit and a driving gear of the second guiding and conveying unit to rotate in opposite directions; the upper end of the sampling tube is communicated with a feed port of a sampling barrel through a pipeline, and an extraction opening is formed in the sampling barrel and communicated with an extraction opening of an exhaust fan. The grain sampler can obtain representative detection samples and improve grain sampling accuracy, and sampling operation is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of grain testing equipment, in particular to a grain sampling machine. Background technique [0002] When the grain purchase station or the national grain depot purchases foreign grain, in order to ensure the quality of the grain purchase, before the grain is put into the warehouse, it is necessary to sample the grain in the truck compartment, specifically to obtain the dust content and water content of the grain. The quality of grain is also a must-test item for grain purchasing stations before purchasing grain. [0003] Grain samplers are also used in existing grain purchase stations or national grain depots. Most of the existing grain samplers are hand-held. into the truck compartment of the freight vehicle to complete the sampling operation of the grain in the truck. Sometimes the hand-held sampler in the prior art cannot reach into the deep position of the truck compartment for sampling, resulting in d...

[0003] Grain samplers are also used in existing grain purchase stations or national grain depots. Most of the existing grain samplers are hand-held. into the truck compartment of the freight vehicle to complete the sampling operation of the grain in the truck. Sometimes the hand-held sampler in the prior art cannot reach into the deep position of the truck compartment for sampling, resulting in deviations in sampling detection, and the hand-held When the sampler is sampling, the operator needs to climb up and down, and the sampling operation is extremely inconvenient
