Mechanical online grain sampler

Abstract

The invention discloses an online grain sampler, comprising a seed protector, a seed baffle, a material receiving hole wheel support frame and the like. The seed protector is an integrated structure integrated with seed separating, seed guiding and seed protecting; the seed protector can be matched with the material receiving hole wheel to separate excessive seeds and also can ensure an acquired sample to be accurately dropped into a detection position; the seed baffle is a mounting plate provided with a semi-elliptical through hole and a return opening; the material receiving hole wheel is a sampling device integrated with multiple functions such as sampling, seed protecting, carrying and cleaning; the support frame is a limit, dustproof and diversion bracket which is provided with a dip angle on one side and has an included angle between the bottom surface and a plumb line larger than a material artesian angle; the upper half part of the material receiving hole wheel extends from the semi-elliptical through hole and the lower half part of the material receiving hole wheel is still in a detection chamber when the material receiving hole wheel is in operation; the detection chamber is relatively sealed, and capable of adapting to high-humidity and high-dust detection environment; and no seed is damaged during sampling, reliability is good, and quantity of the acquired samples can be guaranteed to meet detection requirement.

Description

technical field [0001] The invention relates to an online grain condition detection device and an on-line sampler of the grain moisture on-line detection device, in particular to an on-line sampler of the grain moisture on-line detection device when the grain is dry. Background technique [0002] The online sampler is one of the key components of the on-line detection device for grain condition and the on-line detection device for grain moisture. Reliable on-line sampling is the key to grasp the grain situation in real time. Especially in the drying process of grain, in order to realize real-time control of the drying process and ensure the quality of grain, it is necessary to collect grain samples online in real time. At present, most grain drying adopts artificial timing sampling and timing detection. This method cannot use the detected data to implement real-time control of the drying process; the existing automatic online detection device has not been specially designed...

Problems solved by technology

At present, most grain drying adopts artificial timing sampling and timing detection. This method cannot use the detected data to implement real-time control of the drying process; the existing automatic online detection device has not been specially designed for the grain running status on the drying equipment. For online samplers, the general method is to directly insert the measuring electrode into the grain layer, or expose the measuring electrode to let the grain directly splash onto the detection electrode. The disadvantage of this method is that it has poor adaptability to the detection environment of high humidity and high dust. , the measurement accuracy of the detection device is very low, and there are often phenomena such as debris winding around the measuring device and dust adhering to the measuring electrode, which makes the reliability of the detection device very poor, especially when drying high-humidity grains, the problem is very prominent, until now There is no online detection device that can be directly used to detect the moisture content of grain entering the dryer. The reason is that the problem of online sampling has not been solved.
