Embodiment 1

[0026] This embodiment is a device for spiral sampling on-line detection package, such as figure 1 , 2 shown. The present embodiment comprises: the material receiving bucket 2 that is installed in front of the belt machine head 1, the described material receiving bucket is provided with a sampling groove 201, and the inlet of the described sampling groove is connected with the screw sampler 4, and the described screw sampler A radiation detector 5 is provided on the top, and the outlet of the spiral sampler is connected to the sample packaging machine 3 through a pipeline, and the spiral sampler, radiation detector and sample packaging machine are electrically connected to the sampling controller 6 ( figure 2 The electrical connection is indicated by a dash-dotted line).

[0027] The sampling method in this embodiment is a method of sampling at the head of the belt conveyor, that is, collecting the materials thrown out by the belt conveyor at the head of the belt conveyor. ...

Embodiment 2

[0035] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment about the sampling groove. The horizontal projection of the sampling tank described in this embodiment is a rectangle, the long side of the rectangle is parallel to the axis of the pulley of the belt conveyor, and the bottom of the sampling tank is open to the spiral sampler.

[0036] It is called a "trough" to express its function of holding materials. It does not have the characteristic shape of a general "trough" with a concave bottom in the middle and sides on both sides, but a long strip with a roughly triangular cross-section. In other words, it is a "trough" with one groove side removed and only the bottom and one side of the groove. When sampling, the material is accumulated in the triangular area formed by the bottom of the tank and a side of the tank. When the material on the sampling tank is accumulated to a certain extent, the material will fall naturally d...

Embodiment 3

[0040] This embodiment is an improvement of the above embodiment, and is a refinement of the above embodiment about the spiral sampler. The spiral sampler described in this embodiment includes: a sampling barrel 402, in which a screw push rod 403 driven by a motor 401 is provided, and one end of the sampling barrel is provided with a sampling port as the outlet of the spiral sampler. Output port 404, such as figure 2 shown.

[0041] A spiral sampler is arranged at the bottom of the sampling tank. The rotary push rod of the spiral sampler is consistent with the long direction of the sampling slot, see figure 2 , the bottom of the sampling tank is open to the auger sampler, that is to say, if the auger pusher of the auger sampler does not rotate, the material accumulates on the auger pusher of the auger sampler. The screw push rod is a rotating rod driven by a motor, on which a helical blade is arranged, and the outer circumference of the blade is surrounded by a cylindrica...

Abstract

The invention relates to a packaging online-testing device and method for spiral sampling. The packaging online-testing device for spiral sampling comprises a material-collecting basket installed at the front of a belt handpiece. A sampling groove is formed in the material-collecting basket. The sampling groove is connected with an inlet of a spiral sampler. A ray detector is arranged on the spiral sampler. The outlet of the spiral sampler is connected to a sample packaging machine through a pipeline. The spiral sampler, the ray detector and the sample packaging machine are electrically connected with a sampling controller. According to the packaging online-testing device and method for spiral sampling, sampling ray detecting and packaging are combined through the spiral sampler, the whole process is connected seamlessly, the sampled sample is packaged immediately after the ray is detected, the consistency of sampling and detection can be guaranteed, the detected data are combined with the packaged sample immediately, thereby the on-line detection is completely consistent with the sample, the whole process is totally sealed, and man-made replacing and faking are avoided.

Description

technical field [0001] The invention relates to a device and method for spiral sampling on-line detection and packaging, which is a detection device and method, and a device and method for sampling powdery granular products and detecting packaging in a closed state. Background technique [0002] For the detection of some powdery particles, such as ore sand, coal powder and other powdery bulk products with small particles, sampling and on-line detection are required, and the sampled samples are packaged and preserved, so as to be used as samples in subsequent product transactions or evidence of quality assurance. The existing on-line inspection and sample sampling packages are separated, that is, the data on-line inspection is not the data of the sampling sample, but the product data near the sampling sample. As a result, there is some gap between the detection data of the sample and the data of the online detection, which affects the accuracy of the data. [0003] There ar...
