Adjustable sampling mechanism based on grain sampler

Abstract

The invention discloses an adjustable sampling mechanism based on a grain sampler, and relates to the technical field of grain samplers. The adjustable sampling mechanism comprises a sampling driving assembly, a sampling pipe, a negative pressure fan, a sample splitter, a collection tank, a collection box cooperation, an input control module, a sample point establishment module, a sample point analysis module and an element execution module. According to the invention, information acquisition of a grain sample, establishment of control on a three-dimensional sampling point, operation of analog calculation and generation of a first sampling control signal or a second sampling control signal are realized, and the position of a sampling pipe and the weight of the sampled grain sample are accurately controlled through generation of the first sampling control signal or the second sampling control signal; and the mechanism is more accurate in sampling, wider, deeper and more comprehensive in grain sample collection range, more accurate in subsequent detection and capable of solving the problem that the quality judgment of grain samples is not accurate enough due to the fact that traditional equipment is not accurate enough in sampling.

Description

technical field [0001] The invention relates to the technical field of grain sampling machines, in particular to an adjustable sampling mechanism based on grain sampling machines. Background technique [0002] The electric grain sampling machine is an electric tool that is used to extract samples from the bottom of the deep grain pile and each layer. It is specially designed and manufactured for automatic sampling of vehicle-mounted grain and bulk grain without a cover. It can rotate along the z-axis and Move along the X-axis to control the sampling position, but there are still some shortcomings. It is not accurate enough to control the sampling movement of the sampling mechanism along the X-axis, and when the thickness of the grain is different, the sampling tube cannot be raised and lowered, and only the upper surface of the grain can be taken. grain, and it is impossible to automate and accurately control the sampling of the sampling tube, resulting in the problem of ina...

Problems solved by technology

[0004] The object of the present invention is: by arranging sampling driving assembly, sampling pipe, negative pressure fan, sample divider, collection tank, collection box cooperation, input control module, sample point establishment module, sample point analysis module and element execution module; the present invention Realize the information collection of grain samples, the establishment and control of three-dimensional sampling points, run the simulation calculation and generate the first sampling control signal or the second sampling control signal, which is generated by the first sampling control signal or the second sampling control signal, so as to accurately control the sampling The position of the tube and the precise control of the weight of the grain samples taken make the sampling of this equipment more accurate, the scope of collecting grain samples is wider, deeper, and more comprehensive, which makes the follow-up detection more accurate and solves the problem of grain samples caused by the inaccurate sampling of traditional equipment. Quality judgment is not accurate enough
