Description

Technical field:

[0001] The utility model belongs to the field of coal sampling, in particular to an automatic coal sampling device. Background technology:

[0002] The purpose of coal sampling is to take representative samples, then determine their quality through chemical analysis, and judge whether the sampled coal meets certain standards. Therefore, in the coal industry, coal testing is a very important part of the work.

[0003] In the actual coal mining and sampling process, on-site workers usually use a shovel to shovel out the coal as it falls into the coal bin. Although this method is efficient and convenient, the coal falls very quickly. On-site workers are likely to be hit by falling coal when using the shovel to take samples. Therefore, this sampling method has safety hazards and is relatively dangerous. In addition, the daily coal mining volume is large, and the number of samples that need to be collected is also large. Manual sampling will additionally increase the labor intensity of on-site workers. Utility model content:

[0004] The utility model aims to provide an automatic coal sampling device, and overcomes the deficiencies of the above-mentioned prior art, and effectively solves the existing problems in the coal mining process.

[0005] Contents of the utility model: An automatic coal sampling device comprises a coal storage bin, a sampling barrel is installed on the inclined side wall of the coal storage bin, the inner cavity of the sampling barrel is connected with the inner cavity of the coal storage bin, a sampling groove is slidably connected in the inner cavity of the sampling barrel, the outer end of the sampling groove is fixedly connected to the piston rod end of a cylinder, the cylinder is fixedly installed on the outer end of the sampling barrel, a chute is opened on the bottom wall of the sampling groove, and a sample discharge port is opened on the bottom wall of the sampling barrel.

[0006] Furthermore, a sample guide tube is installed on the sample discharge port, a sample storage box is installed at the bottom end of the sample guide tube, and a movable material blocking assembly is arranged at the discharge port at the bottom end of the sample storage box.

[0007] Furthermore, the movable material baffle assembly includes a T-shaped baffle, a socket is opened on the side wall of the sample storage box, the T-shaped baffle is inserted into the socket, and a slot matching the T-shaped baffle is opened on the inner cavity side wall of the sample storage box.

[0008] Furthermore, a handle is installed on the outer end of the T-shaped baffle.

[0009] Furthermore, a discharge chute is installed at the bottom discharge port of the sample storage box.

[0010] Furthermore, a cone head is installed on the inner end side wall of the sampling groove.

[0011] Furthermore, a reinforcing support frame is installed between the coal storage bin and the sampling tube.

[0012] Furthermore, the installation angle of the sampling tube is inclined downward.

[0013] The beneficial effects of the utility model are as follows: when the cylinder pushes the sampling trough to slide out of the sampling tube, the coal particles in the coal storage bin can automatically fall into the inner cavity of the sampling trough, and finally slide into the sample storage box for temporary storage, thereby avoiding the safety hazards brought about by manual sampling, and also reducing the labor intensity of on-site workers, saving time and effort.

Specific implementation method:

[0017] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention is now described with reference to the accompanying drawings:

[0018] like Figure 1 to Figure 2 As shown, an automatic coal sampling device comprises a coal storage bin 1, a sampling tube 2 is installed on the oblique side wall of the coal storage bin 1, the inner cavity of the sampling tube 2 is connected with the inner cavity of the coal storage bin 1, a sampling groove 3 is slidably connected in the inner cavity of the sampling tube 2, the outer end of the sampling groove 3 is fixedly connected to the piston rod end of a cylinder 4, the cylinder 4 is fixedly installed on the outer end of the sampling tube 2, a chute 5 is opened on the bottom wall of the sampling groove 3, a sample discharge port 6 is opened on the bottom wall of the sampling tube 2, and a sample discharge port 6 is installed on the sample discharge port 6 There is a sample guide tube 7, a sample storage box 8 is installed at the bottom end of the sample guide tube 7, a movable material blocking assembly is arranged at the bottom discharge port of the sample storage box 8, the movable material blocking assembly includes a T-shaped baffle 9, a socket 10 is opened on the side wall of the sample storage box 8, the T-shaped baffle 9 is inserted into the socket 10, a slot 11 matching the T-shaped baffle 9 is opened on the inner cavity side wall of the sample storage box 8, a handle 12 is installed at the outer end of the T-shaped baffle 9, and a discharge chute 13 is installed at the bottom discharge port of the sample storage box 8.

[0019] Specifically, when the cylinder 4 pushes the sampling groove 3 to slide out of the sampling tube 2 , the coal particles in the coal storage bin 1 can fall into the inner cavity of the sampling groove 3 .

[0020] During actual use, the cylinder 4 is started to push the sampling slot 3 to slide out of the sampling tube 2 for a distance, and the inner end of the sampling slot 3 is extended into the inner cavity of the coal storage bin 1 to form a sampling gap. When the piston rod of the cylinder 4 is pushed out to the maximum distance, the chute 5 and the sample discharge port 6 are just connected. At the same time, the coal particles in the coal storage bin 1 fall into the inner cavity of the sampling slot 3, and enter the sample guide tube 7 through the chute 5 and the sample discharge port 6 in turn. The sampled coal finally falls into the sample storage box 8 for temporary storage. After the sampling is completed, the piston rod of the cylinder 4 is retracted, and the sampling slot 3 is retracted into the sampling tube 2, and the sampling gap formed by the sampling slot 3 is closed; when recovering the sample, the handle 13 is pulled out to pull the T-shaped baffle 9 out of the socket 10, and the sample coal in the sample storage box 8 slides into the recovery bag through the unloading chute 13.

[0022] Specifically, the cone head 14 facilitates the sampling slot 3 to enter the coal storage bin 1, thereby reducing the sampling resistance.

[0023] During actual use, when the sampling groove 3 extends into the inner cavity of the coal storage bin 1, the cone head 14 can quickly push away the coal in the coal storage bin 1 to reduce the sampling resistance; the strengthened support frame 15 can enhance the stability of the sampling device; and the downwardly tilted sampling tube 2 facilitates the rapid sliding of the sample coal.
