Description

Technical Field

[0001] This invention relates to coal sample preparation and cutting technology, specifically to a coal sample preparation and cutting device. Background Technology

[0002] In the field of coal testing and analysis, coal sample preparation and cutting is a crucial step, as its cutting quality directly affects the accuracy and reliability of subsequent coal sample testing results. Currently, traditional coal sample preparation and cutting methods have many drawbacks and cannot meet the high requirements of modern coal testing.

[0003] Traditional coal slitting equipment has a low level of automation, with most operations requiring manual labor. From coal stacking and flattening to slitting and unloading, all stages rely on manual operation. This not only increases the labor intensity of workers but also introduces significant arbitrariness, making it difficult to ensure consistency and standardization in each slitting operation, further impacting the accuracy and efficiency of coal slitting. For example, during manual stacking, variations in operator experience and technique can lead to differences in the shape and uniformity of the stack, resulting in inconsistent flattening and slitting effects. Simultaneously, manual unloading is inconvenient; the slitted coal must be manually removed by workers, which is not only inefficient but also prone to secondary contamination of the coal samples.

[0004] With the continuous development of the coal industry and the increasing requirements for coal quality testing, the existing traditional coal sample preparation and cutting equipment can no longer meet the actual needs. There is an urgent need for a new type of coal sample preparation and cutting equipment that can improve cutting accuracy and efficiency and achieve automated operation. Summary of the Invention

The outer surface of the mounting shaft is connected to a first driving mechanism, the outer surface of the flipping block is connected to a second driving mechanism, and the outer surface of the transmission shaft is connected to a third driving mechanism.

[0007] Furthermore, the drive separation mechanism includes a first rotating drive component fixedly connected to the support platform. The output end of the first rotating drive component is fixedly connected to a connecting shaft rotatably connected to the support platform via a coupling. An electromagnet block is fixedly connected to the top of the connecting shaft. A connecting iron block is attracted to the top of the electromagnet block. The connecting iron block is fixedly connected to the bottom of the receiving box.

[0008] Furthermore, the moving mechanism includes a transmission column slidably connected to the slitting box, the bottom end of the transmission column being connected to a support plate, and the top end of the transmission column being fixedly connected to a third telescopic drive member fixedly connected to the slitting box via a connecting block.

[0009] Furthermore, the connecting mechanism includes an electromagnet ring fixedly connected to the slitting box, and a connecting iron ring fixedly connected to the top of the receiving box.

[0010] Furthermore, a mounting frame is fixedly connected to the conical feed hopper, a second rotation drive is fixedly connected to the mounting frame, a stirring shaft that is rotatably connected to the output end of the second rotation drive is fixedly connected to the second rotation drive, a spiral rod is fixedly connected to the bottom end of the stirring shaft, a stirring plate is fixedly connected to the outer surface of the stirring shaft, and a stirring column is fixedly connected to the bottom of the stirring plate.

[0011] Furthermore, the first driving mechanism includes a third rotational driving component fixedly connected to the mounting platform. The output end of the third rotational driving component is fixedly connected to a first driving shaft. A first driving gear is fixedly sleeved on the outer surface of the first driving shaft. A second driving gear is meshed with the outer surface of the first driving gear and fixedly sleeved on the mounting shaft.

[0012] Furthermore, the second drive mechanism includes a fourth telescopic drive member fixedly connected to the transmission frame. The output end of the fourth telescopic drive member is fixedly connected to a transmission rack via a connecting block. A transmission gear is meshed on one side of the transmission rack.

[0014] Compared with the prior art, the coal sample preparation and cutting device provided by the present invention has the following beneficial effects: The first drive mechanism rotates the mounting shaft, causing the conical feed hopper, pressure plate, and slitting box to rotate sequentially above the receiving box. In conjunction with various drive mechanisms and telescopic drive components, this completes the operations of coal stacking, flattening, fixing, and flipping for slitting. During the slitting process, the coal's own gravity is used to fall, combined with the cross-shaped slitting plate to achieve slitting, avoiding the coal particle breakage problem caused by the compression of traditional slitting plates. This effectively prevents damage to the slitting plate due to compression and greatly improves slitting accuracy. Simultaneously, automated operation reduces manual intervention, significantly improving slitting efficiency and meeting the needs of large-scale coal sample preparation and slitting, providing more accurate samples for subsequent coal sample testing.

[0015] A second rotary drive unit is connected to the mounting bracket on the conical feed hopper, driving the stirring shaft to rotate, which in turn activates the screw rod, stirring plate, and stirring column. The rotation of the screw rod causes the coal to move downwards evenly, effectively preventing material jamming during feeding and ensuring smooth feeding. The rotation of the stirring plate and stirring column uniformly mixes the coal, ensuring thorough mixing. Combined with the rotation of the receiving box, the coal is evenly piled into the cone within the box, further improving the pile-up accuracy. The uniformity of the pile-up directly affects the subsequent flattening and cutting effects, thereby improving the accuracy of coal sample testing and providing a reliable guarantee for coal quality inspection. Furthermore, the entire feeding and pile-up process is highly automated, making it easy for operators to use. Attached Figure Description

[0027] The first drive mechanism drives the mounting shaft 4 to rotate, which in turn drives the conical feed hopper 5 to rotate, positioning it above the receiving box 3. Mixed coal is then placed into the conical feed hopper 5, flowing through it to the center of the receiving box 3. Simultaneously, the electromagnet block 23 is energized to attract the connecting iron block 24. The first rotation drive 21 then drives the connecting shaft 22 to rotate, which in turn drives the electromagnet block 23 to rotate, causing the connecting iron block 24 and the receiving box 3 to rotate, resulting in a uniform cone-shaped distribution of the coal. After the cone-shaped distribution is complete, the first drive mechanism drives the mounting shaft 4 to rotate, causing the pressure plate 7 to rotate above the receiving box 3. Then, the first telescopic drive 6 drives the pressing plate 7 to move downwards, flattening the coal behind the pile cone. Simultaneously, during flattening, the receiving box 3 rotates, ensuring the coal in the pile cone is evenly flattened. The pressing plate 7 then moves upwards, and the first drive mechanism rotates the mounting shaft 4 and the slitting box 12 above the receiving box 3. The second telescopic drive 8 then drives the transmission frame 9 downwards, which in turn drives the tilting block 10, transmission shaft 11, and slitting box 12 downwards, bringing the slitting box 12 into contact with the receiving box 3. Then, the electromagnet ring 41 at the bottom of the slitting box 12 is energized to attract the connecting iron ring 42 at the top of the receiving box 3, fixing the receiving box 3 onto the slitting box 12. Then... The third telescopic drive 32 drives the transmission column 31 to move downwards, which in turn drives the support plate 14 to move downwards, pressing the support plate 14 against the coal in the receiving box 3 to fix the coal. Then, the electromagnet block 23 connected to the bottom of the receiving box 3 is de-energized. Simultaneously, the second telescopic drive 8 drives the transmission frame 9 to move upwards, causing the slitting box 12 and the receiving box 3 to move upwards. Then, the second drive mechanism drives the tilting block 10 to rotate, causing the transmission shaft 11, the slitting box 12, and the receiving box 3 to rotate 180°. Then, the third telescopic drive 32 drives the transmission column 31 to move, which in turn drives the support plate 14 to move downwards within the slitting box 12. Finally, the coal in the receiving box 3... The coal is cut by the cross-shaped cutting plate 13 and enters the cutting box 12, achieving automated and uniform cutting of the coal. This greatly improves the cutting accuracy and efficiency. Simultaneously, the coal flows downwards under gravity and is isolated by the cutting plate 13, effectively preventing damage to the cutting plate 13 due to pressure between it and the plate. It also prevents the crushing of some coal particles caused by the traditional cutting plate 13, which would affect the cutting accuracy. After cutting, the two diagonally opposite support plates 14 in the cutting box 12 move downwards, causing the diagonally cut coal to move downwards and escape the isolation of the cutting plate 13. Then, a third drive mechanism drives the transmission shaft 11 to rotate, which in turn drives the cutting box 12 to rotate.At this point, the coal detached from the cutting plate 13 detaches from the support plate 14 under the action of centrifugal force and enters the cutting box 12. Then, it drives the two support plates 14 that just detached from the cutting plate 13 to move upwards, allowing them to rejoin the cutting plate 13. Subsequently, the second drive mechanism drives the tilting block 10 to rotate to its initial position. Simultaneously, the coal sample remaining on the support plate 14 after cutting enters the receiving box 3. The receiving box 3 is then fixed to the electromagnet block 23, and the cutting box 12 is no longer connected to the receiving box 3. The first drive mechanism then drives the mounting shaft 4 to rotate, causing the cutting box 12 to rotate to the discharge position. This causes the support plate 14 to move downwards, disengaging it from the cutting box 12, while simultaneously rotating the cutting box 12, discharging the coal sample inside. This achieves automatic separation of the cut coal sample and automatic discharge of the separated coal, eliminating the need for manual handling and simplifying operation.

[0028] A mounting frame 51 is fixedly connected to the conical feed hopper 5. A second rotation drive component 52 is fixedly connected to the mounting frame 51. The second rotation drive component 52 is a servo motor. The servo motor is controlled by a PLC programming program, which can control the servo motor to rotate forward and backward and the rotation angle. A stirring shaft 53 that is rotatably connected to the mounting frame 51 is fixedly connected to the output end of the second rotation drive component 52. A spiral rod 54 is fixedly connected to the bottom end of the stirring shaft 53. A stirring plate 55 is fixedly connected to the outer surface of the stirring shaft 53. A stirring column 56 is fixedly connected to the bottom of the stirring plate 55.

[0029] After coal is placed into the conical feed hopper 5, the hopper 5 then piles the coal into the receiving box 3. At this time, the second rotating drive 52 drives the stirring shaft 53 to rotate, which in turn drives the screw rod 54 to rotate. The screw rod 54 moves the coal downward, allowing it to pass evenly through the conical feed hopper 5 into the receiving box 3, preventing material jamming and improving the smoothness of the feed. Simultaneously, the stirring shaft 53 drives the stirring plate 55 to rotate, which in turn drives multiple stirring columns 56 to rotate. The stirring columns 56 evenly stir the coal, ensuring uniform mixing and even distribution of the coal entering the receiving box 3. This, combined with the rotation of the receiving box 3, ensures that the coal is evenly piled into a cone within the receiving box 3, further improving the accuracy of the pile and enhancing the accuracy of subsequent coal sample testing.

[0030] Working Principle: The first drive mechanism drives the mounting shaft 4 to rotate, which in turn drives the conical feed hopper 5 to rotate above the receiving box 3. Then, the mixed coal is placed into the conical feed hopper 5, and the coal passes through the hopper to the center of the receiving box 3. Simultaneously, the electromagnet block 23 is energized and attracts the connecting iron block 24. The first rotation drive component 21 then drives the connecting shaft 22 to rotate, which in turn drives the electromagnet block 23 to rotate. The electromagnet block 23 then drives the connecting iron block 24 and the receiving box 3 to rotate, resulting in a uniform cone-shaped distribution of the coal. After the cone-shaped distribution is complete, the first drive mechanism drives the mounting shaft 4 to rotate, causing the pressing plate 7 to rotate. The coal is moved above the receiving box 3, and then the first telescopic drive 6 drives the pressing plate 7 to move downwards, flattening the coal behind the pile. During this flattening process, the receiving box 3 rotates, ensuring the coal in the pile is evenly flattened. The pressing plate 7 then moves upwards, and the first drive mechanism rotates the mounting shaft 4 and the slitting box 12 above the receiving box 3. The second telescopic drive 8 then drives the transmission frame 9 downwards, which in turn drives the tilting block 10, the transmission shaft 11, and the slitting box 12 downwards, bringing the slitting box 12 into contact with the receiving box 3. Finally, the electromagnet ring 41 at the bottom of the slitting box 12 is energized to attract the connecting iron ring 42 at the top of the receiving box 3, thus fixing the receiving box 3 in place. On the slitting box 12, the third telescopic drive 32 drives the transmission column 31 to move downwards, which in turn drives the support plate 14 to move downwards, pressing the support plate 14 against the coal in the receiving box 3 to fix the coal. Then, the electromagnet block 23 connected to the bottom of the receiving box 3 is de-energized, and at the same time, the second telescopic drive 8 drives the transmission frame 9 to move upwards, causing the slitting box 12 and the receiving box 3 to move upwards. Then, the second drive mechanism drives the tilting block 10 to rotate, which in turn drives the transmission shaft 11, the slitting box 12, and the receiving box 3 to rotate 180°. Then, the third telescopic drive 32 drives the transmission column 31 to move, which in turn drives the support plate 14 to move downwards within the slitting box 12. The coal in the receiving box 3 is then cut by the cross-shaped cutting plate 13 and enters the cutting box 12, achieving automated and uniform coal cutting. This greatly improves the cutting accuracy and efficiency. Simultaneously, the downward flow of coal under gravity and the isolation provided by the cutting plate 13 effectively prevent damage to the cutting plate 13 due to pressure between it and the coal. It also prevents the crushing of coal particles caused by the traditional cutting plate 13, which would affect the cutting accuracy. After cutting, the two diagonally opposite support plates 14 in the cutting box 12 move downwards, causing the diagonally cut coal to move downwards and escape the isolation of the cutting plate 13. Then, the third drive mechanism drives the transmission shaft 11 to rotate.The drive shaft 11 drives the slitting box 12 to rotate. At this time, the coal detached from the slitting plate 13 detaches from the support plate 14 under the action of centrifugal force and enters the slitting box 12. Then, it drives the two support plates 14 that had just detached from the slitting plate 13 to move upwards, allowing them to re-enter the slitting plate 13. Subsequently, the second drive mechanism drives the tilting block 10 to rotate, returning it to its initial position. Simultaneously, the coal sample remaining on the support plate 14 after slitting enters the receiving box 3. The receiving box 3 is then fixed to the electromagnet block 23. When the cutting box 12 is no longer connected to the receiving box 3, the first drive mechanism drives the mounting shaft 4 to rotate, causing the cutting box 12 to rotate to the discharge position. This then drives the support plate 14 downwards, causing it to move away from the cutting box 12. Simultaneously, the cutting box 12 rotates, discharging the coal sample inside. This achieves automatic separation of the cut coal sample and automatic discharge of the separated coal, eliminating the need for manual handling and simplifying operation.
