Abstract
Description
Technical Field
[0001] The invention relates to the technical field of raw coal transportation devices, and in particular to a weighing device for uniform feeding of raw coal during transportation. Background Art
[0002] The transportation of raw coal refers to the process of transporting the mined, unwashed and processed coal from the mining area or coal producing area to the consumption area or processing area. This process usually involves multiple modes of transportation and complex logistics networks to ensure that the coal can be delivered to the destination safely, efficiently and economically. In the transportation of raw coal, it is also necessary to consider the loading and unloading, storage, and transshipment of coal. These links require the use of professional equipment and technology to ensure the quality and safety of coal. At the same time, it is also necessary to formulate reasonable transportation plans and logistics plans to optimize the transportation process, reduce transportation costs, and improve transportation efficiency. Railway transportation is the main mode of long-distance transportation of raw coal. It has the advantages of large capacity, fast speed, low cost, and little impact from weather. It is particularly suitable for long-distance transportation of bulk goods. The railway department usually builds special coal transportation routes, such as coal dedicated lines or coal transportation channels, to meet the needs of coal transportation.
[0003] When raw coal is mined, the overall size is different and the volume difference may be extremely large. When merchants buy coal near the raw coal mine, it may be difficult to control the quantity by weighing due to the larger volume of raw coal, and it is difficult to feed the coal evenly, so that the volume of raw coal in each container is the same. There is a certain randomness, and it is difficult to guarantee the sales quality. Summary of the invention
[0004] (I) Technical problems to be solved: In view of the deficiencies of the prior art, the present invention provides a weighing device for uniform feeding of raw coal during transportation, which has the advantages of quantitative weighing and uniform distribution of coal, and solves the problem of weighing and feeding of raw coal.
[0005] (II) Technical solution: In order to achieve the above-mentioned quantitative weighing and uniform distribution of coal, the present invention provides the following technical solution: a weighing device for uniform feeding of raw coal transportation, comprising a transportation component, a feed port and a coal transport box, wherein the transportation component drives the raw coal transportation through a synchronous belt, and the raw coal is put into the open feed port, and the raw coal falls downward from the feed port into the coal transport box, and the coal transport box is arranged on a transportation track, and the coal transport box containing the raw coal is transported away by the transportation track, and a shielding component is arranged on the side of the feed port away from the transportation component, and the shielding component can block the opening of the feed port. A movable plate is provided in the coal box, and the movable plate and the bottom of the coal box are connected by a spring, so that when there is a heavy object on the movable plate, it will move downward, and when there is no heavy object on the movable plate, it will restore its original horizontal height due to the elastic action. A height detection component is provided on the inner wall of the coal box, and the height detection component can detect the horizontal height of the movable plate. The weight of the raw coal in the coal box is calculated according to the horizontal height of the movable plate. At the same time, when the raw coal in the coal box increases, a signal is sent to the shielding component. The heavier the weight of the raw coal, the larger the shielding area of the feeding port is.
[0006] Preferably, a slide groove is provided on the shielding component, and a shielding plate is provided in the slide groove, and the shielding plate can slide in the slide groove.
[0007] Preferably, the chute is inclined upward, so that when the shielding plate shields the feed inlet, the raw coal can be blocked.
[0008] Preferably, the shielding plate is provided with pores, the size of which is capable of allowing small-volume raw coal to pass through and blocking large-volume raw coal.
[0009] Preferably, a buffer plate is provided on the open inner wall of the feed port, the buffer plate is arc-shaped, and at least one buffer plate is provided on each side, and the buffer plates on both sides are staggered in an up-and-down manner.
[0010] Preferably, a torsion spring is provided at the connection between the buffer plate and the inner wall of the feed port. When a large volume of raw coal falls onto the buffer plate, the buffer plate can flip downward with the torsion spring installation position as the axis. At the same time, an infrared probe is provided on the inner wall of the feed port, which can count the number of times the buffer plate flips downward.
[0011] Preferably, the buffer plate is provided with grid holes for allowing small-volume raw coal to fall directly downward.
[0012] Preferably, a resistance coil is provided inside the height detection component, and the resistance coil is arranged in a vertical direction. A circuit terminal is provided on the movable plate and is in contact with the resistance coil in the height detection component. When the movable plate moves up and down, the length of the coil connected to the current can be changed.
[0013] Preferably, a side baffle is provided on the side of the feed inlet.
[0014] Preferably, the synchronous belt is provided with a groove, which is rectangular and perpendicular to the transport direction of the synchronous belt.
[0015] (III) Beneficial effects: Compared with the prior art, the present invention provides a weighing device for uniform feeding of raw coal transportation, which has the following beneficial effects: 1. The weighing device for uniform feeding of raw coal transportation can detect the weight of raw coal in the coal box in real time and accurately through the connection of the movable plate and the spring and the coordinated use of the height detection component, and automatically adjust the shielding area of the shielding component when the preset weight is reached, so as to realize quantitative weighing and precise control of raw coal transportation, which not only improves the transportation efficiency, but also ensures the weight consistency of each batch of raw coal. The design of the shielding component effectively avoids the entry of large pieces of raw coal when the coal box is about to be full, thereby preventing the occurrence of overweight, which not only protects the transportation equipment from overweight damage, but also ensures the safety and stability of the entire transportation process. The device realizes real-time monitoring and calculation of the weight of raw coal through the built-in weighing mechanism (movable plate, spring, height detection component), without the need to set up an additional complex weighing device under the coal box. This design simplifies the equipment structure, reduces manufacturing and maintenance costs, and is Because it adopts automatic control and real-time monitoring technology, the device can maximize transportation efficiency while ensuring transportation safety. The flexible adjustment of the shielding component ensures uniform feeding of raw coal and avoids transportation interruption or delay caused by accumulation of large pieces of raw coal. The device can adapt to the transportation needs of raw coal of different sizes and shapes. By adjusting the shielding area of the shielding component and the sensitivity of the height detection component, it can realize precise control and measurement of raw coal of different weights and volumes. This structure not only realizes the weighing of the transported raw coal, but also can quantitatively control the raw coal in each coal transport box. After quantitative control, the volume of raw coal in each coal transport box can also be controlled, so that the raw coal in each coal transport box can be evenly distributed. In addition, because springs and movable plates are provided at the bottom of the coal transport box to realize weighing, when unloading coal in the coal transport box, the movable plate can play a driving role to speed up the unloading process.
[0016] 2. The weighing device for uniform feeding of raw coal transportation, when the coal box is close to full load, the control system issues a command to drive the shield plate to slide down in the chute through a mechanical or electric device. Since the chute is designed to be tilted upward, the shield plate will gradually increase the shielding area of the feed inlet during the sliding process. At the same time, the pore design on the shield plate ensures that only small-volume raw coal can pass through, while large-volume raw coal is effectively blocked outside the feed inlet. In addition, the upward-tilted shield plate blocks and intercepts the coal, so that the larger raw coal stays on the shield plate and enters the next coal box, ensuring the continuity of work. The sliding design of the shield plate in the chute allows it to be adaptively adjusted according to the weight or height of the raw coal in the coal box. When the coal box is close to full load, the shield plate will automatically slide downward to increase the shielding area and reduce the entry of large pieces of raw coal, thereby achieving dynamic balance and precise control.
[0017] 3. The weighing device for uniform feeding of raw coal transportation is provided with a buffer plate on the open inner wall of the feed port. The buffer plate is arc-shaped and at least one is provided on each side. The buffer plates on both sides are staggered up and down. A torsion spring is provided at the connection between the buffer plate and the inner wall of the feed port. When a large volume of raw coal falls onto the buffer plate, the buffer plate can turn downward with the torsion spring installation position as the axis. At the same time, an infrared probe is provided on the inner wall of the feed port, which can count the number of times the buffer plate turns downward. When a large volume of raw coal blocks falls into the feed port from above, they will first contact the arc-shaped buffer plate. Since the buffer plate has certain elasticity and toughness, it will turn downward with the torsion spring installation position as the axis when impacted. Thereby, the direct impact force of the raw coal blocks on the inner wall of the feed port is reduced. The infrared probe is installed on the inner wall of the feed port, which can monitor the flipping action of the buffer plate in real time and count it. When the count exceeds a certain value, it means that too many large coal blocks have fallen. The feed port is blocked by adjusting the shielding component to prevent too many large coal blocks from falling in, thereby ensuring that the volume of coal in each coal box is relatively uniform. If large pieces of raw coal fall directly into the coal box, it will produce a large impact, which will not only cause damage to the equipment, but also the displacement of the movable plate in the coal box will first increase and then rebound partially, resulting in detection deviation. The buffer plate is used to buffer large pieces of raw coal during the falling process to reduce the impact on the coal box.
[0018] 4. The weighing device for uniform feeding of raw coal transportation has a resistance coil inside the height detection component, and the coil is arranged in a vertical direction. The circuit endpoints on the movable plate are in contact with the resistance coil in the height detection component. When the movable plate moves up and down, the length of the coil connected to the current can be changed. Referring to the principle and structure of the sliding rheostat, by changing the length of the resistance coil connected to the current, the moving distance of the movable plate in the vertical direction can be accurately reflected. As the movable plate moves, the effective resistance value of the resistance coil changes in real time. When current passes through the resistance coil, according to Ohm's law, the current in the circuit is inversely proportional to the resistance, and the voltage is proportional to the resistance. Therefore, as the length of the resistance coil changes, the current and voltage in the circuit will also change accordingly. These changes can be detected and recorded by sensors or measuring instruments in the circuit, so that the position information of the movable plate can be obtained in real time. Compared with other complex height detection devices, this design has a simple structure, mainly composed of a resistance coil and a movable plate, easy to manufacture and maintain, and relatively low cost.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] See also Figure 1-Figure 3 The weighing device for uniform feeding of raw coal transportation comprises a transportation component 1, a feeding port 2 and a coal transport box 3. The transportation component 1 drives the raw coal transportation through a synchronous belt 11, and the raw coal is put into the open feeding port 2. The raw coal falls downward from the feeding port 2 into the coal transport box 3. The coal transport box 3 is arranged on a transportation track 31, and the coal transport box 3 filled with raw coal is transported away by the transportation track 31. A shielding component 21 is arranged on the side of the feeding port 2 away from the transportation component 1, and the shielding component 21 can adjust the open area of the feeding port 2. A movable plate 32 is arranged in the coal transport box 3. The movable plate 32 and the bottom of the coal box 3 are connected by a spring, so that when there is a heavy object on the movable plate 32, it will move downward. When there is no heavy object on the movable plate 32, it will restore its original horizontal height due to the elastic action. A height detection component 33 is provided on the inner wall of the coal box 3. The height detection component 33 can detect the horizontal height of the movable plate 32. The weight of the raw coal in the coal box 3 is calculated by the horizontal height of the movable plate 32. At the same time, when the raw coal in the coal box 3 increases, a signal is sent to the shielding component 21. The heavier the weight of the raw coal, the larger the shielding area of the shielding component 21 for the opening of the feed port 2.
[0023] The raw coal is transported by the synchronous belt 11 on the transport component 1, and the raw coal is put into the feed port 2, and then poured into the coal box 3. The transport track 31 transports the coal box 3 filled with raw coal. A shielding component 21 is arranged beside the feed port 2. Because the coal blocks are of different sizes when the raw coal is mined, and the difference between large pieces of raw coal and small pieces of raw coal is large. When the coal box 3 is almost full, the feed port 2 is partially shielded by the shielding component 21 to prevent large pieces of coal from entering the coal box 3 from the feed port 2, so that the raw coal in the coal box 3 is overweight and quantitative weighing cannot be achieved. By shielding the shielding component 21 and leaving a gap, it is possible to prevent large pieces of raw coal from falling into the coal box 3 while maintaining the synchronous belt 11 to transport the coal, thereby playing a screening role, and, A movable plate 32 is provided at the bottom of the coal transport box 3. The movable plate 32 can be moved up and down in the coal transport box 3 by a spring provided at the bottom. As the amount of raw coal in the coal transport box 3 increases, the height of the movable plate 32 decreases and the spring is compressed. The horizontal height of the movable plate 32 is detected by a height detection component 33 provided on the side of the inner wall of the coal transport box 3, so that the weight of the raw coal in the coal transport box 3 can be calculated. There is no need to set an additional weighing device under the coal transport box 3, and it does not affect the transportation of the coal transport box 3. When the height detection component 33 detects the movement of the movable plate 32, it can send a signal to control the shielding component 21 to block the feeding port 2. The heavier the weight of the raw coal in the coal transport box 3, the lower the horizontal height of the movable plate 32, and the larger the shielding area of the shielding component 21 for the feeding port 2.
[0024] See also Figure 4-Figure 5 The shielding component 21 is provided with a slide groove 212, and a shielding plate 211 is provided in the slide groove 212. The shielding plate 211 can slide in the slide groove 212. The slide groove 212 is inclined upward, so that when the shielding plate 211 blocks the feed port 2, the raw coal can be blocked. The shielding plate 211 is provided with pores, and the size of the pores can allow small-volume raw coal to pass through and block large-volume raw coal.
[0025] When the coal transport box 3 is close to being fully loaded, the control system issues a command to drive the shielding plate 211 to slide downward in the chute 212 through a mechanical or electric device. Since the chute 212 is designed to be tilted upward, the shielding plate 211 will gradually increase the shielding area of the feed port 2 during the sliding process. At the same time, the pore design on the shielding plate 211 ensures that only small-volume raw coal can pass through, while large-volume raw coal is effectively blocked outside the feed port. In addition, the upward-tilted shielding plate 211 blocks and intercepts the coal, so that the larger raw coal stays on the shielding plate 211 and enters the next coal transport box 3, ensuring the continuity of work. The sliding design of the shielding plate 211 in the chute 212 allows it to be adaptively adjusted according to the weight or height of the raw coal in the coal transport box 3. When the coal transport box 3 is close to being fully loaded, the shielding plate 211 will automatically slide downward to increase the shielding area and reduce the entry of large pieces of raw coal, thereby achieving dynamic balance and precise control.
[0026] See also Figure 6-Figure 8 A buffer plate 23 is provided on the open inner wall of the feed port 2. The buffer plate 23 is arc-shaped, and at least one is provided on each side, and the buffer plates 23 on both sides are staggered up and down. A torsion spring is provided at the connection between the buffer plate 23 and the inner wall of the feed port 2. When a large volume of raw coal falls onto the buffer plate 23, the buffer plate 23 can flip downward with the torsion spring installation position as the axis. At the same time, an infrared probe is provided on the inner wall of the feed port 2, which can count the number of times the buffer plate 23 flips downward. The buffer plate 23 is provided with grid holes for small volume raw coal to fall downward.
[0027] When larger raw coal blocks fall into the feed port 2 from above, they will first contact the arc-shaped buffer plate 23. Since the buffer plate has certain elasticity and toughness, it will flip downward with the torsion spring installation position as the axis when impacted, thereby reducing the direct impact force of the raw coal blocks on the inner wall of the feed port. At the same time, small raw coal or coal powder can fall smoothly through the grid holes on the buffer plate and enter the subsequent processing or transportation process. The infrared probe is installed on the inner wall of the feed port, which can monitor the flipping action of the buffer plate in real time and count it. When the count exceeds a certain value, it means that too many large coal blocks have fallen. The shielding component 21 is adjusted to shield the feed port to prevent too many large coal blocks from falling in, thereby ensuring that the coal in each coal box 3 is relatively uniform. If large pieces of raw coal fall directly into the coal box 3, it will produce a large impact, which will not only damage the equipment, but also the displacement of the movable plate 32 in the coal box 3 will first increase and then rebound a part, resulting in detection deviation. The buffer plate 23 is used to buffer the large pieces of raw coal during the falling process to reduce the impact on the coal box 3.
[0028] The height detection component 33 is provided with a resistance coil inside, and the coil is arranged in a vertical direction. The circuit terminal on the movable plate 32 is in contact with the resistance coil inside the height detection component 33. When the movable plate 32 moves up and down, the length of the coil connected to the current can be changed, referring to the principle and structure of the sliding rheostat.
[0029] By changing the length of the resistance coil connected to the current, the moving distance of the movable plate 32 in the vertical direction can be accurately reflected. As the movable plate 32 moves, the effective resistance value of the resistance coil changes in real time. When the current passes through the resistance coil, according to Ohm's law, the current in the circuit is inversely proportional to the resistance, and the voltage is proportional to the resistance. Therefore, as the length of the resistance coil changes, the current and voltage in the circuit will also change accordingly. These changes can be detected and recorded by sensors or measuring instruments in the circuit, so that the position information of the movable plate 32 can be obtained in real time. Compared with other complex height detection devices, this design has a simple structure, mainly consisting of a resistance coil and a movable plate 32, is easy to manufacture and maintain, and has a relatively low cost.
[0030] A side baffle 22 is provided on the side of the feed inlet 2, and the side baffle 22 can prevent the raw coal from falling out from the side of the feed inlet 2, thereby reducing the burden of manual cleaning.
[0031] See also Fig. 9 The synchronous belt 11 is provided with a groove 111, which is rectangular and perpendicular to the transportation direction of the synchronous belt 11. The groove 111 can effectively reduce the sliding of the raw coal on the synchronous belt 11 during transportation. At the same time, the groove 111 can accommodate some small-volume raw coal, so that it is located in the lower layer of the transported raw coal, and can easily fall into the feed port 2, avoiding being blocked by large-volume raw coal and unable to fall into the feed port 2.
[0032] Working principle: The raw coal is transported by the synchronous belt 11 on the transport component 1, and the raw coal is put into the feed port 2, and then poured into the coal box 3. The transport track 31 transports the coal box 3 filled with raw coal. A shielding component 21 is arranged next to the feed port 2. Because the coal blocks are of different sizes when the raw coal is mined, and the difference between large pieces of raw coal and small pieces of raw coal is large. When the coal box 3 is almost full, the feed port 2 is partially blocked by the shielding component 21 to prevent large pieces of coal from entering the coal box 3 from the feed port 2, so that the raw coal in the coal box 3 is overweight and quantitative weighing cannot be achieved. By blocking the shielding component 21 and leaving a gap, it is possible to prevent large pieces of raw coal from falling into the coal box 3 while maintaining the synchronous belt 11 to transport the coal, thereby playing a screening role, and, A movable plate 32 is provided at the bottom of the coal transport box 3. The movable plate 32 can be moved up and down in the coal transport box 3 by a spring provided at the bottom. As the amount of raw coal in the coal transport box 3 increases, the height of the movable plate 32 decreases and the spring is compressed. The horizontal height of the movable plate 32 is detected by a height detection component 33 provided on the side of the inner wall of the coal transport box 3, so that the weight of the raw coal in the coal transport box 3 can be calculated. There is no need to set an additional weighing device under the coal transport box 3, and it does not affect the transportation of the coal transport box 3. When the height detection component 33 detects the movement of the movable plate 32, it can send a signal to control the shielding component 21 to block the feeding port 2. The heavier the weight of the raw coal in the coal transport box 3, the lower the horizontal height of the movable plate 32, and the larger the shielding area of the shielding component 21 for the feeding port 2.
