Description
Technical Field
The invention belongs to the technical field of feed processing, and relates to an automatic material sampling system and a sampling method.
Background
With the increasing severity of food safety problems, the quality requirements of feed products, such as nutritional indexes, hygienic indexes and the like, are higher and higher. In order to ensure that each batch of feed product can meet the quality requirements, the product after the ingredients is generally sampled and detected before the feed is granulated. Currently, the sampling process is mostly done manually by operators who take part in the sample from the silo and collect it in a sampling bag before the product, which has been dosed in the mixer, is transferred to the silo and introduced from the silo into the granulator. However, when different batches of products are discharged from the bin, the products in the middle of the bin generally fall off first, so that staggered mixing occurs between the different batches of products, the quality condition of the batch of materials cannot be truly reflected by the taken samples, and the phenomena of missing taking, re-taking and the like exist, so that the detection accuracy is greatly influenced.

The materials in the mixer are conveyed to the bottom of the hoister by the conveyor, then are conveyed upwards to the top of the hoister by the hoister, and finally slide into the storage bin by the material guide chute. When a sample needs to be taken, the three-way material guiding mechanism is opened, and the material enters the sample distribution and collection mechanism through the three-way material guiding mechanism to be stored so as to detect the taken material.
Preferably, the conveyor is a scraper conveyor, and the elevator is a bucket elevator.
Furthermore, the three-way material guiding mechanism comprises a feeding pipe, a sampling pipe and a discharging pipe, wherein the feeding pipe is arranged below the material guiding elephant trunk and communicated with the material guiding elephant trunk, the sampling pipe and the discharging pipe are arranged at the bottom of the feeding pipe, one end of the discharging pipe is communicated with the bottom of the feeding pipe, the other end of the discharging pipe is communicated with the material guiding elephant trunk, and the sample distributing and collecting mechanism is located at the bottom of the sampling pipe. During sampling, the feeding pipe is opened, and a part of the materials in the material guiding chute enters the feeding pipe and then falls into the sample distributing and collecting mechanism through the sampling pipe; after the sample is collected, the feeding pipe and the sampling pipe are closed, the materials in the material guiding slide pipe do not enter the feeding pipe any more, and the residual materials in the feeding pipe return to the material guiding slide pipe through the discharging pipe.
Furthermore, the feeding pipe and the discharging pipe are both inclined, and one end of the discharging pipe, which is positioned at the feeding pipe, is higher than one end of the discharging pipe, which is positioned at the material guiding chute.
