A kind of material automatic sampling system and sampling method

Abstract

The invention relates to a material automatic sampling system and a sampling method. The sampling system includes a conveyor, a hoister, a material guide hose pipe and a controller. A tee joint material guide mechanism communicated with the material guide hose pipe is disposed thereunder. The bottom of the tee joint material guide mechanism is equipped with a sample distribution collection mechanism, and the controller is in electric connection with the tee joint material guide mechanism and the sample distribution collection mechanism respectively. When sampling is needed, the tee joint material guide mechanism is opened, and materials enter the sample distribution collection mechanism through the tee joint material guide mechanism for storage. Compared with the prior art, the system andmethod provided by the invention carry out sampling before materials enter a material bin through a mixer, can avoid the cross mixing phenomenon of different batches of materials during sampling in the material bin, effectively guarantee the accuracy of sampling, can realize accurate sampling of all batches of materials, greatly improve the detection accuracy, are easy to operate, also avoid wasteof materials, and ensure stable production.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and relates to a material automatic sampling system and a sampling method. Background technique [0002] With the increasingly severe food safety issues, the quality requirements of feed products such as nutritional indicators and hygiene indicators are getting higher and higher. In order to ensure that each batch of feed products can meet the quality requirements, the products after batching are usually sampled and tested before feed pelleting. At present, the sampling process is mostly done manually by the operator. When the finished ingredients in the mixer are transported to the silo, and before the silo is introduced into the granulator, some samples are taken from the silo and collected in the sampling bag. However, when different batches of products are discharged from the silo, the products in the middle of the silo usually fall first, resulting in intermixing between different b...

Problems solved by technology

However, when different batches of products are discharged from the silo, the products in the middle of the silo usually fall first, resulting in intermixing between different batches of products, so that the samples taken out cannot truly reflect the quality of the batch of materials situation, and there are phenomena such as missing and retaking, which greatly affect the accuracy of detection
