Problems solved by technology

[0003] And when existing coal is sampled, utilize the sampling head on the sampling machine to carry out insert sampling to the piled coal, but because be when coal is rotated to the inside of sampling head by screw rod, the outer surface layer of its piled coal also is This leads to the fact that the sampled samples cannot be well guaranteed, so that the quality of the coal cannot be judged fairly, and the quality of the sample is reduced. At the same time, a lot of coal ash will be collected during the sampling, and the coal ash will cause pollution to the working environment. , working for a long time in a polluted environment, the health of the staff will also be affected, thereby increasing the induction of occupational diseases and reducing safety;

Embodiment 1

[0031] like Figure 1-7 As shown in the figure, a follow-up coal sample collection mechanism proposed by the present invention includes a support frame 1, a connecting frame 3 is fixedly connected to the outer surface of the right side of the support frame 1 near the upper end, and the outer surface of the right side of the connecting frame 3 is fixedly connected There is a transport rack 2, and the support rack 1, the connecting rack 3, and the transport rack 2 are in a U-shaped structure. The outer surface of the lower end of the connecting rack 3 is provided with a chute 4 near the middle position, and the inner ends of the chute 4 are fixedly connected. There is a first screw rod 5, and a reclaiming mechanism 6 is provided on the outer surface of the lower end of the connecting frame 3;

[0032]The reclaiming mechanism 6 includes a mounting member 61, a first threaded hole 62, a movable groove 63, a second screw rod 64, a reclaiming rod 65, a screw rod 66, a first rotating...

Embodiment 2

[0036] like Figure 2-9 As shown, a receiving mechanism 7 is arranged inside the material transport rack 2;

[0037] The receiving mechanism 7 includes a receiving hopper 71, a filter plate 72, a filter screen 73, a swing motor 74, a cavity 75, a storage box 76, a recovery port 77, a conveyor belt 78, and an electric roller 79; the cavity 75 is opened inside the conveying rack 2. Near the middle position, a receiving hopper 71 is fixedly arranged on the left outer surface of the conveying rack 2. The receiving hopper 71 and the cavity 75 are connected to each other. The inner lower end of the cavity 75 is provided with a receiving box 76 for collecting coal ash. A recovery port 77 is provided on the right outer surface of the transport rack 2 near the lower end, and the recovery port 77 is matched with the storage box 76 for taking the storage box 76 out of the cavity 75;

[0038] A swing motor 74 runs through the outer surface of the rear end of the conveying rack 2 near the...

Abstract

The invention relates to the technical field of coal sample collection, in particular to a follow-up coal sample collection mechanism, comprising a support frame, the right outer surface of the support frame is fixedly connected with a connecting frame near the upper end, and the right outer surface of the connecting frame is fixedly connected There is a material transport frame, and the support frame, the connecting frame, and the material transport frame are in a U-shaped structure; the present invention can strip the coal on the surface layer of the coal pile, so that the sampled coal can be used for the coal inside the coal pile, so that it can Effectively collect samples, improve the fairness of sample evaluation, and improve the quality of sampling. At the same time, it can filter and sieve the coal samples that fall to the surface, so that the coal ash mixed in the coal samples can be shaken off, thereby improving the efficiency of collection. When taking samples, excessive coal ash will not cause environmental pollution in the work area, ensuring the personal safety of the staff, reducing the induction of occupational diseases, and improving the safety of the staff.

Description

technical field [0001] The invention relates to the technical field of coal sample collection, in particular to a follow-up coal sample collection mechanism. Background technique [0002] In the coal trading process, the tens of thousands of tons of coal provided by the supplier should have the same surface quality as the internal quality. However, the coal traded in the market comes from a wide range of sources, and the quality of coal from different batches and origins varies greatly. In addition, some coal sales units, out of commercial interests, dope the coal with fake and shoddy products. Therefore, the sampling and testing of commercial coal is an indispensable and important part of coal trading, in order to judge the quality of coal fairly. , the coal shall be sampled according to the prescribed, scientific and reasonable methods; [0003] In the existing coal sampling, the sampling head on the sampling machine is used to insert and sample the piles of coal. However...
