Technical Field

[0001] The utility model relates to the technical field of intelligent processing, in particular to an intelligent full-automatic coal feeding and transferring device based on PLC for coal yards. Background Technique

[0002] Coal is the fossil fuel with the richest reserves and the widest distribution area on the earth. The elements that make up the organic matter of coal mainly include carbon, hydrogen, oxygen, nitrogen, sulfur, etc. In addition, there are extremely small amounts of elements such as phosphorus, fluorine, chlorine, and arsenic; after coal is mined, it is necessary to conduct sample tests on the coal to ensure that the coal products put on the market meet the usage standards. During the process of feeding and transferring coal samples, a coal feeding and transferring mechanism is usually used.

[0003] Chinese Patent CN113786903A discloses an intelligent coal feeding and transferring mechanism. During the entire feeding and transferring process, the coal is processed in a closed container, which avoids the pollution of the surrounding air environment caused by a large amount of dust generated during the coal feeding and transferring process. At the same time, the entire feeding and transferring process realizes intelligent monitoring and management, and no workers are required to operate, thus avoiding the harm to the physical health of workers caused by coal dust.

[0004] However, in this intelligent coal feeding and transferring mechanism, there is a situation of coal spilling during the process of the conveyor belt transporting coal. This intelligent coal feeding and transferring mechanism cannot collect the spilled coal, which will cause the coal to accumulate in the transfer box, making it inconvenient to collect and clean and resulting in a waste of resources.

Detailed implementation manners

[0047] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0048] See Figures 1-8 As shown, an intelligent fully automatic coal feeding and transfer device based on PLC in a coal yard includes a feeding box 100 and a transfer box 104. The feeding box 100 is provided with a feed inlet 101, and a discharge outlet 102 is opened on the side of the feeding box 100 close to the transfer box 104. A guide plate 103 is fixedly arranged at the discharge outlet 102 of the feeding box 100. A conveying mechanism 400 for conveying coal from the feeding box 100 into the transfer box 104 is arranged in the feeding box 100. A collecting pipe 105 for collecting the coal dropped during the conveying process is fixedly arranged at the bottom surface of the feeding box 100. A collecting and transporting mechanism 200 for transporting the collected coal into the transfer box 104 is arranged on the collecting pipe 105. An anti-blocking mechanism 500 for preventing the collecting pipe 105 from being blocked when collecting coal is arranged in the collecting pipe 105. A crushing mechanism 300 for stirring and crushing the large coal blocks entering is arranged in the transfer box 104.

[0049] Coal enters the feed box 100 through the feed inlet 101 and is transported to the transfer box 104 by the conveying mechanism 400. During the transportation process, some coal may fall from the feed box 100. The fallen coal is collected through the collection pipe 105 and transported back into the transfer box 104 by the collection and transportation mechanism 200. The crushing mechanism 300 in the transfer box 104 stirs and crushes the large pieces of coal.

[0050] See Figures 2-4 As shown, the collection and transportation mechanism 200 includes a conveying pipe 201, a first rotating motor 202, a first rotating shaft 203, and rotating blades 204. The conveying pipe 201 is fixedly arranged at the discharge port of the collection pipe 105 and is perpendicular to the collection pipe 105. One end of the collection pipe 105 is communicated with the transfer box 104. One end of the first rotating shaft 203 rotatably penetrates the conveying pipe 201, and the other end of the first rotating shaft 203 extends into the transfer box 104. The rotating blades 204 are fixedly arranged on the first rotating shaft 203. The first rotating motor 202 is fixedly arranged on the side of the conveying pipe 201 away from the transfer box 104, and the output end of the first rotating motor 202 is in transmission connection with the first rotating shaft 203.

[0051] The first rotating motor 202 drives the first rotating shaft 203 and the rotating blades 204 to rotate, forming a rotating air flow or mechanical force in the conveying pipe 201 to transport the collected coal to the transfer box 104, achieving the effect of collecting the coal that spills during the transportation process.

[0052] See Figures 3-5 As shown, the conveying mechanism 400 includes a third motor 401, a driving sprocket 402, a driven sprocket 403, and a conveying table 405. Two sets of the driving sprocket 402 and the driven sprocket 403 are symmetrically arranged along the central axis of the feed box 100. The driving sprocket 402 and the driven sprocket 403 are both rotatably arranged on the inner wall of the feed box 100. The driving sprocket 402 and the driven sprocket 403 are in transmission connection through a chain 404. The conveying table 405 is fixedly arranged between the two side walls of the feed box 100 and is located in the middle of the chain 404. The third motor 401 is fixedly arranged on the side of the feed box 100, and the output end of the third motor 401 is in transmission connection with the driving sprocket 402.

[0053] Start the third motor 401 to drive the driving sprocket 402 to rotate. The driving sprocket 402 drives the driven sprocket 403 to rotate through the chain 404, thereby driving the coal on the conveying table 405 to move from the feed box 100 to the transfer box 104.

[0054] See Figures 3-5 As shown, multiple sets of scraping plates 406 are fixedly arranged between the two symmetrically arranged chains 404.

[0055] The scraper 406 is fixed between two symmetrically arranged chains 404. As the chains 404 rotate, the scraper 406 pushes the coal on the conveyor table 405 into the transfer box 104, achieving the effect of improving the conveying efficiency.

[0056] See Figures 3-6 As shown, the crushing mechanism 300 includes a second rotating motor 301, a second rotating shaft 302, crushing blades 303 and crushing blades 304. One end of the second rotating shaft 302 is rotatably connected to the side wall of the transfer box 104, and the other end of the second rotating shaft 302 rotatably penetrates the side wall of the transfer box 104. Multiple groups of crushing blades 303 are equidistantly distributed along the axial direction of the second rotating shaft 302, and multiple crushing blades 303 are equidistantly distributed along the circumferential direction of the second rotating shaft 302 in each group. Multiple crushing blades 304 are provided on the arc of the crushing blades 303. The second rotating motor 301 is fixedly arranged on the side of the transfer box 104, and the output end of the second rotating motor 301 is drivingly connected to one end of the second rotating shaft 302 penetrating the side wall of the transfer box 104.

[0057] After the coal enters the transfer box 104, start the second rotating motor 301 to drive the second rotating shaft 302 and the crushing blades 303 to rotate. The crushing blades 304 on the crushing blades 303 cut and crush the large pieces of coal, effectively crushing the large pieces of coal into smaller particles and improving the utilization rate of the coal.

[0058] See Figure 6 As shown, the crushing mechanism 300 further includes a baffle 305 and a crushing block 306. The baffle 305 is fixedly arranged on the inner wall of the transfer box 104 and above the crushing blades 303. The cross-section of one side inner wall of the baffle 305 is arc-shaped, and the crushing block 306 is fixedly arranged on the arc-shaped inner wall of the baffle 305.

[0059] The baffle 305 divides the interior of the transfer box 104 to form a specific crushing space. The crushing block 306 is fixed on the arc-shaped inner wall of the baffle 305. When the coal passes by, the crushing block 306 performs secondary crushing on it, further improving the crushing effect of the coal.

[0060] See Figures 7-8 As shown, the anti-blocking mechanism 500 includes a fixed rod 501, a rotating base 502, a third rotating shaft 503 and a dredging block 504. The fixed rod 501 is fixedly arranged in the collecting pipe 105 along the diameter direction of the collecting pipe 105. A rotating base 502 is fixedly arranged at the center of the collecting pipe 105 on the fixed rod 501. One end of the third rotating shaft 503 is drivingly connected to the output end of the rotating base 502, and the dredging block 504 is fixedly arranged at the other end of the third rotating shaft 503 and close to the connection between the collecting pipe 105 and the feeding box 100.

[0061] Start the rotary base 502 on the fixing rod 501 to drive the third rotating shaft 503 and the dredging block 504 to rotate. The dredging block 504 rotates in the collecting pipe 105 to prevent coal from clogging in the collecting pipe 105.

[0062] See Figure 8 As shown, the anti-clogging mechanism 500 further includes a rotating rod 505. One end of the rotating rod 505 abuts against the inner wall of the collecting pipe 105, and a plurality of the rotating rods 505 are equidistantly distributed along the circumferential direction of the third rotating shaft 503.

[0063] The rotating rod 505 abuts against the inner wall of the collecting pipe 105. As the third rotating shaft 503 rotates, the rotating rod 505 generates disturbances in the collecting pipe 105 to further prevent coal from clogging.

[0064] The above embodiments only represent one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
