Wheat weighing and accurate sampling bin

Abstract

The invention belongs to the technical field of grain storage bins, and particularly relates to a wheat weighing accurate sampling bin which comprises a storage barrel, a cover body is arranged above the storage barrel, through holes are formed in the cover body and the storage barrel in an up-down corresponding mode, sampling outer pipes are fixedly installed in the through holes, first sampling openings are formed in the pipe walls of the sampling outer pipes, and second sampling openings are formed in the pipe walls of the sampling outer pipes. The bottom of the sampling outer pipe is provided with an electromagnetic valve for controlled discharging, the sampling inner pipe is coaxially arranged in the sampling outer pipe, the pipe wall of the sampling inner pipe is provided with a sampling port II matched with the sampling port I, the cover body is provided with a driving system for driving the sampling inner pipe, and the diameter of the outer wall of the sampling inner pipe is equal to that of the inner wall of the sampling outer pipe. The grain sampling device has the characteristics of accurate sampling and no influence on grain storage quality.

Description

technical field [0001] The invention belongs to the technical field of grain storage bins, in particular to a weighing and accurate sampling bin for wheat. Background technique [0002] Now in the wheat purchase or wheat storage and wheat grain processing industry, it is necessary to store grain in the warehouse, but the existing grain storage does not have the function of accurate sampling, and the lid of the warehouse needs to be opened manually when sampling, and manual sampling with a sampler is extremely inconvenient. It is convenient and the sampling volume is inaccurate; secondly, every time the grain in the warehouse is used, it is necessary to take samples to test and evaluate the quality of the grain in the warehouse. Therefore, it is necessary to frequently open the lid of the warehouse, which will reduce the quality of grain storage and seriously affect the subsequent storage of grain. Contents of the invention [0003] In order to solve the problems raised in ...
