Description

Technical Field

[0001] The utility model relates to the technical field of automatic sampling equipment for ironmaking raw materials in the metallurgical industry, in particular to an automatic sampling device for a belt conveyor. Background Art

[0002] Coke, sintered ore and other materials are one of the most important raw materials for iron-making blast furnaces in the field of iron and steel metallurgy. Their physical properties have an important impact on blast furnace production. Before the materials enter the blast furnace, in order to determine the physical properties and powder particle conditions of various materials, it is necessary to sample and analyze the materials entering the furnace. Traditionally, sampling is mostly done manually in the material pile. The sampling operation is not only time-consuming and labor-intensive, but also inefficient. In addition, when the materials are piled up, most of the block materials are piled on the surface of the pile, and the small particles of materials sink to the bottom of the pile. The materials are unevenly distributed in the pile to be sampled, and the samples taken from the unevenly distributed piles are not representative enough. The sampling results are highly biased and cannot truly reflect the true performance of the materials.

[0003] For this reason, it has been gradually developed that the sampling point is set at the output end of the belt conveyor, and an automatic sampling mechanism is set up to sample through the automatic sampling mechanism, as disclosed in the patent document of Chinese patent application No. 201620361243.2. In the existing sampling device of the belt conveyor, the automatic sampling mechanism is mostly directly set at the output end of the belt conveyor. Although it can also perform sampling, when it is not sampling, the automatic sampling mechanism located at the output end of the belt conveyor is easy to affect the normal feeding of the belt conveyor, and the convenience of use is poor. Utility Model Content

[0004] The utility model aims to provide an automatic sampling device for a belt conveyor.

[0005] The technical solution for achieving the purpose of the utility model is: an automatic sampling device for a belt conveyor, comprising a linear guide rail and a sampling tube, the linear guide rail is non-vertical, the sampling tube is movably installed on the linear guide rail, the sampling tube is transmission-connected to a driving mechanism and can be moved along the linear guide rail by the driving mechanism, the sampling tube is inclined, the upper end of the sampling tube is provided with a sampling port opening upward, and the lower end of the sampling tube is correspondingly provided with a collecting bucket.

[0006] Furthermore, the upper end of the sampling tube is closed, and the sampling port is arranged on the tube wall of the sampling tube. The sampling port is opened on the tube wall of the sampling tube, and the caliber of the sampling port can be relatively large. After the upper end of the sampling tube is closed, the upper end of the sampling tube does not leak material, and the reliability of sampling is better.

[0007] Furthermore, the sampling tube is rollingly mounted on the linear guide rail via a roller. The sampling tube can be rollingly mounted on the linear guide rail or slidingly mounted on the linear guide rail. Compared with sliding mounting, the friction force of movement during rolling mounting is smaller and the movement is easier.

[0008] Furthermore, the driving mechanism is a cylinder, and the driving mechanism is parallel to the linear guide rail. The driving mechanism can be a cylinder, a lead screw or a motor belt, etc. Compared with other structures, the cylinder body is small and the structure is simple.

[0009] Furthermore, the linear guide rail is inclined. The linear guide rail can be arranged horizontally or inclined. Preferably, the linear guide rail is arranged inclined.

[0010] Furthermore, an upper limiter and a lower limiter are respectively provided on the linear guide rail and at both ends of the moving path of the sampling tube. The upper limiter and the lower limiter respectively limit the two ends of the moving path of the sampling tube to prevent the sampling tube from moving out of the linear guide rail, so that the operation of the sampling tube on the linear guide rail is more stable and reliable.

[0011] Furthermore, the linear guide rail and the driving mechanism are both fixedly mounted on the collecting bucket. The linear guide rail and the driving mechanism can be fixedly mounted on the collecting bucket or fixedly mounted on other frames. When fixedly mounted on the collecting bucket, other frame settings can be omitted, and the structure is simpler and more compact.

[0012] Furthermore, the sampling tube is located below the output end of the belt conveyor. When working, the sampling tube is located below the output end of the belt conveyor, and the sampling tube takes the material output and flowing from the belt conveyor, so that the sample is more representative.

[0013] Furthermore, the automatic sampling device for the belt conveyor is located below the belt conveyor, and the extended line of the moving path of the sampling tube forms an angle а with the extended line of the conveying path of the belt conveyor, and the angle а is an acute angle. Under this setting, the automatic sampling device for the belt conveyor is located directly below the belt conveyor, which can reduce the floor space on the one hand, and avoid affecting the normal unloading of the belt conveyor on the other hand.

[0014] Furthermore, a material receiving barrel is connected to the lower part of the collecting hopper through a material pipe. The sample collected by the sampling tube is temporarily collected in the collecting hopper and then transported to the material receiving barrel along the material pipe. The arrangement of the material pipe and the material receiving barrel facilitates the removal of samples.

[0015] Further, the lower end of the sampling tube is located in the collecting bucket. The lower end of the sampling tube can be located above the collecting bucket or in the collecting bucket. After being located in the collecting bucket, the sampling tube can drop into the collecting bucket more reliably without spilling.

[0016] Furthermore, a vertical portion is extended downward from the lower end of the sampling tube. The vertical portion can guide the material so that the material output along the sampling tube falls vertically to avoid spilling of the material.

[0017] The utility model belt conveyor automatic sampling device, through the arrangement of the linear guide rail and the sampling tube thereon, enables the sampling tube to move and change position along the linear guide rail, so that as the sampling tube moves and changes position, the sampling tube can perform different operations, such as when the sampling tube is extended and the sampling port is located on the falling path of the material at the output end of the belt conveyor, the material output by the belt conveyor falls into the sampling tube from the sampling port for sampling; after the sampling tube is retracted and located outside the falling path of the material at the output end of the belt conveyor, sampling is stopped. The utility model belt conveyor automatic sampling device, driven by the driving mechanism, can not only automatically sample with high sampling efficiency, but also is located at the output end of the belt conveyor to sample the material being transported by the belt conveyor, and can effectively avoid the problem of insufficient representativeness of "piled materials" and low sampling authenticity. In addition, the conversion of the sampling state of the utility model is accompanied by the movement and repositioning of the sampling tube. In the non-sampling state, the sampling tube retreats outside the falling path of the material at the output end of the belt conveyor, which will not affect the normal material discharge of the belt conveyor. The use effect is better and the convenience is higher. BRIEF DESCRIPTION OF THE DRAWINGS

The sampling tube 2 is tilted, and a sampling port 21 with an upward opening is provided at the upper end of the sampling tube 2, and a collecting bucket 3 is correspondingly provided at the lower end of the sampling tube 2.

The inclined sampling tube 2 with a sampling port 21 can be used to receive samples and also allow the samples inside to fall by their own weight.

[0024] The utility model belt conveyor automatic sampling device is arranged below the output end of the belt conveyor 10, and is used to sample the materials transported on the belt conveyor 10. In the process of conveying materials by the belt conveyor 10, when sampling, the driving mechanism 20 drives and drives the sampling tube 2 to move along the linear guide rail 1, so that the sampling tube 2 moves to the falling path of the materials at the output end of the belt conveyor 10; after the sampling port 21 of the sampling tube 2 is located on the falling path of the materials at the output end of the belt conveyor 10, the materials output by the belt conveyor 10 fall into the sampling tube 2 from the sampling port 21, and are collected into the collecting bucket 3 along the sampling tube 2, so that the sample is completed.
