Multifunctional grain sampling machine

Abstract

A multifunctional grain sampling machine comprises a sampling part (1) and a sample separating part (2), wherein the sampling part (1) is fixedly arranged at the top of the sample separating part (2); the multifunctional grain sampling machine is characterized in that an air inlet / outlet (7) is formed in a central position of a barrel bottom (5) of the sampling part (1) in a penetrating way; a cylindrical filter core tank (4) is arranged inside the barrel bottom (5) in a connecting way; a filter casing (3) sleeves the filter core tank (4). The multifunctional grain sampling machine is integrally simple in structure, and multifunctional; the multifunctional grain sampling machine can skillfully integrate a sampling system, a dust-filtering system, a dust-removing system and a sample-separating system, so that operations of the four systems are completely at one time; the multifunctional grain sampling machine ensures trueness of an obtained sample; especially, under the premise that a sealing cap is not opened, a dust-removing problem is solved relatively well; the cost in the using process is reduced, deformation of a barrel cover is prevented, frequent replacement of a dust separator is not required, and the problems of air leakage caused by dropping of a sealing ring and the like are avoided.

Description

technical field [0001] The invention relates to the technical field of a grain cutting machine, in particular to a multifunctional grain cutting machine. technical background [0002] During the commercial circulation of granular grains, it is often necessary to conduct quality inspections on their samples. How to extract a broadly representative sample directly affects its test results and economic value. [0003] The traditional method of cutting and dividing samples is to use the handle needle-type metal cutting tube to cut the required sample quantity from the grain pile, and then use the traditional needle tripod-type sample divider to divide the cut samples once or several times. , until the required test samples are obtained. Such sampling and sampling methods are slow and labor intensive. [0004] With the need for high commodity circulation speed, many distribution companies are gradually using electric sampling machines to sample grains on-site. Take a certain ...

AI Technical Summary

Problems solved by technology

Under the action of strong negative pressure, the small impurities contained in the cut grain samples are adsorbed on the dust compartment, and the dust compartment is blocked by continuous use, causing the dust compartment to deform or break

If it is not cleaned in time, it will directly affect the sampling effect, and it may also cause damage to the fan due to the increased load.

If the sealing cover of the sample tube is often opened to clean up the dust, on the one hand, the workload will be increased, and the dust pollution will also be increased.

Over time, the sealing cover will be deformed and the sealing ring will fall off, resulting in air leakage and malfunctioning
