Description

Technical Field

[0001] This invention relates to the field of sintering trolley material feeding technology, and in particular, to a roller feeder with automatic material height adjustment. Background Technology

[0002] In the sintering process, the flatness of the sintering surface directly affects sintering efficiency and determines the ratio of finished sinter to recycled ore. The leveling device is a key component ensuring the flatness of the sintering surface. Currently, the most widely used leveling device is a fixed, rear-mounted type, arranged independently from the roller distributor. Due to its fixed structure, it cannot be adjusted in real time according to changes in the thickness of the sintering layer, resulting in poor leveling performance under varying layer thicknesses. Furthermore, the height adjustment of existing leveling devices mostly requires stopping the machine, which is cumbersome and cannot be adapted to the actual layer thickness in a timely manner, affecting sintering production efficiency and sintering effect. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a roller-type material distributor with automatic adjustment of material height.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A roller-type material distributor with automatic height adjustment includes: a frame; a roller-type material distribution assembly mounted on the frame, having a material input end and a material output end; a flat plate having a scraping end for scraping material on a platform cart, the flat plate being mounted on the roller-type material distribution assembly and rotatable relative to the roller-type material distribution assembly to adjust the height of the scraping end of the flat plate, and the scraping end extending out of the roller-type material distribution assembly; and an adjustment drive mechanism connected to the flat plate to drive the flat plate to rotate.

[0005] Furthermore, the roller-type fabric assembly includes a fabric roller and a mounting frame, the mounting frame being connected to the machine frame; the fabric roller is rotatably mounted on the mounting frame along its own axis; the fabric roller is arranged in a downward and rightward inclined direction, and a drive motor capable of driving the fabric roller to rotate is mounted on the mounting frame.

[0006] Furthermore, the flat plate is lower than the lowest fabric roller, and the flat plate is inclined along the inclined arrangement direction of the fabric roller. The material output by the roller fabric assembly will fall into the flat plate or the right side of the flat plate.

[0007] Furthermore, the upper end of the flat plate is provided with a rotating shaft, which is rotatably mounted on the mounting frame along its own axis.

[0008] Furthermore, the mounting bracket is provided with support seats at both ends of the rotating shaft, and the support seats are provided with through holes. The two ends of the rotating shaft extend into the through holes and are fitted with bearings between them and the inner wall of the through holes.

[0009] Furthermore, the mounting bracket is provided with an auxiliary support frame, the auxiliary support frame is provided with an opening groove with an opening on the right side, the middle part of the rotating shaft is embedded in the opening groove, and the rotating shaft and the opening groove are clearance fit.

[0010] Furthermore, one end of the mounting bracket is hinged to the frame, and the other end is connected to the frame via a telescopic rod that is adjustable in length. One end of the telescopic rod is hinged to the frame, and the other end is hinged to the mounting bracket.

[0011] Furthermore, the adjustment drive mechanism includes an adjustment motor, the output shaft of which is connected to the rotating shaft via a transmission connection.

[0012] Furthermore, the output shaft of the regulating motor is connected to the reducer, the reducer having an extended power shaft, and the power shaft is connected to the rotating shaft via a coupling.

[0013] Furthermore, the reducer has an outwardly extending manual adjustment shaft, the rotation of which can drive the power shaft to rotate; and the torque can only be transmitted unidirectionally through the power shaft or the output shaft to the power shaft.

[0014] The present invention has the following beneficial effects: This device directly mounts the flat plate onto the roller-type material distribution assembly. With the help of an adjusting drive mechanism, the flat plate can rotate relative to the roller-type material distribution assembly, thus flexibly adjusting the height of the scraping end. This allows the flattening height to be adjusted in real time according to the actual material layer thickness on the sintering trolley, eliminating the need for downtime adjustments as required by existing devices. This avoids production interruptions caused by downtime adjustments and ensures a flat and uniform flattening effect under different material layer thicknesses, significantly improving sintering efficiency and the quality of the finished sinter. Furthermore, the roller-type material distribution assembly and the flat plate are integrated, eliminating the need for separate installation space and mounting frames for the flattening device, optimizing the overall equipment layout and saving installation space in the sintering production line. Additionally, the integration of the roller-type material distribution assembly and the flat plate allows the material distributed by the roller-type material distribution assembly to be immediately flattened by the flat plate, resulting in less resistance and wear during scraping, and reducing material overflow from the sides. Meanwhile, the adjustment function can be achieved simply by adjusting the drive mechanism in conjunction with the leveling plate, resulting in a simpler structure. This not only reduces equipment manufacturing and maintenance costs but also minimizes potential malfunctions caused by structural complexity, improving equipment operational stability and facilitating daily inspection and maintenance. Since the scraping end of the leveling plate extends beyond the material output end of the roller-type feeding assembly, the material can immediately pass through the leveling plate after being output from the roller-type feeding assembly, avoiding the problems of asynchronous feeding and leveling, and significant leveling delays, that occur with existing independently arranged leveling devices. This effectively prevents material accumulation and overflow issues common in post-leveling devices, or the compaction and agglomeration of the material surface after pre-feeding, ensuring a uniform thickness and good looseness of the material layer. This provides a high-quality material layer foundation for the stable operation of the subsequent sintering process, further guaranteeing the stability of the sintering process and the high-quality output of sintered ore.

[0022] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a roller feeder with automatic material height adjustment, comprising a frame 100, a roller feed assembly 200, a flat material plate 300, and an adjustment drive mechanism 400.

[0023] The roller-type fabric assembly 200 is mounted on the frame 100. The roller-type fabric assembly 200 has a material input end and a material output end. Material enters the roller-type fabric assembly 200 from the material input end and exits from the material output end of the roller-type fabric assembly 200. For example... Figure 1 As shown, the upper end of the roller fabric assembly 200 is the material input end, and the lower end is the material output end. The roller fabric assembly 200 is arranged at an angle, and the roller fabric assembly 200 is tilted to the right from top to bottom. The material output end is the lower right end of the roller fabric assembly 200.

[0024] The flat material plate 300 has a scraping end 310 for scraping material on the platform cart. The flat material plate 300 is mounted on the roller-type fabric assembly 200 and can rotate relative to the roller-type fabric assembly 200 to adjust the height of the scraping end of the flat material plate 300. The scraping end 310 extends out of the roller-type fabric assembly 200; specifically, the scraping end 310 extends out of the material output end of the roller-type fabric assembly 200. An adjustment drive mechanism 400 is mounted on the roller-type fabric assembly 200 and is connected to the flat material plate 300 to drive the flat material plate 300 to rotate.

[0025] In a preferred embodiment of this invention, a roller feeder with automatic material leveling height adjustment is provided. The material leveling plate 300 is directly mounted on the roller feeder assembly 200. With the assistance of the adjustment drive mechanism 400, the material leveling plate 300 can rotate relative to the roller feeder assembly 200, thereby flexibly adjusting the height of the scraper end 310. This allows the material leveling height to be adjusted in real time according to the actual material layer thickness on the sintering trolley, eliminating the need for machine stoppage adjustments as in existing devices. This avoids production interruptions caused by machine stoppage adjustments and ensures a flat and uniform material leveling effect under different material layer thicknesses, significantly improving sintering efficiency and the quality of the finished sinter. Furthermore, the roller feeding assembly 200 and the flat material plate 300 of this device are integrated together, eliminating the need to reserve separate installation space and mounting frame for the flat material device, thus optimizing the overall layout of the equipment and saving installation space in the sintering production line. At the same time, the adjustment function can be achieved simply by adjusting the drive mechanism 400 in conjunction with the flat material plate 300, making the structure simpler. This not only reduces the manufacturing and maintenance costs of the equipment but also reduces the potential for failures caused by structural complexity, improves the stability of equipment operation, and facilitates daily inspection and maintenance. Because the scraping end 310 of the flat plate 300 extends out of the material output end of the roller feeding assembly 200, the material can immediately pass through the flat plate 300 to complete the leveling operation after being output from the roller feeding assembly 200. This avoids the problems of asynchronous feeding and leveling and large leveling delay that occur in existing independently arranged leveling devices. It effectively prevents the defects of material accumulation and overflow that are prone to occur in post-leveling devices, or the compaction and agglomeration of the material surface after pre-feeding. It ensures that the material layer maintains a uniform thickness and good looseness, providing a high-quality material layer foundation for the stable operation of the subsequent sintering process, and further ensuring the stability of the sintering process and the high-quality output of sintered ore. Furthermore, the integration of the roller-type fabric assembly 200 and the flat plate 300 provides additional technical advantages. Compared to the prior art where the flat plate 300 and roller-type fabric assembly 200 are spaced apart, the flat plate 300 of this invention is closer to the roller-type fabric assembly 200. This allows the material laid by the roller-type fabric assembly 200 to be immediately flattened by the flat plate 300. In the prior art, the flat plate 300 and roller-type fabric assembly 200 are relatively far apart, requiring a longer and larger amount of material to be pushed backward when flattening the material. When material is scraped flat, it tends to accumulate and easily overflows from both sides, resulting in significant resistance and wear on the flat plate 300. However, the flat plate 300 of this invention is integrated with the roller-type material distribution assembly 200, which effectively avoids this problem. When material falls into the trolley, it is immediately scraped flat by the flat plate 300, and any excess material is easily scraped to the rear of the trolley where there is no material distribution yet, reducing material overflow to both sides of the trolley. At the same time, it reduces material accumulation at the scraping point of the flat plate 300, and also reduces the resistance when the flat plate 300 scrapes material.

[0026] Reference Figure 1In some embodiments of the present invention, the roller-type fabric assembly 200 includes a fabric roller 210 and a mounting frame 220, the mounting frame 220 being connected to the frame 100; the fabric roller 210 is rotatably mounted on the mounting frame 220 along its own axis; the fabric roller 210 is arranged in a downward and rightward inclined direction, and a drive motor 230 capable of driving the fabric roller 210 to rotate is mounted on the mounting frame 220. The fabric roller 210's downward and rightward inclined arrangement, combined with the drive motor 230 driving its rotation, utilizes the guiding effect of the inclined structure to smoothly convey material from the material input end to the output end, preventing material accumulation and retention on the fabric roller 210, thus improving fabric distribution efficiency; simultaneously, the drive motor 230 can stably control the rotation speed of the fabric roller 210, providing a stable fabric distribution rhythm basis for the subsequent flattening plate 300 to adjust the flattening height according to the material layer thickness, avoiding fluctuations in material layer thickness due to unstable fabric distribution speed, and ensuring the uniformity of the flattening effect.

[0027] Reference Figure 1 and Figure 3 In a further embodiment of the present invention, the flat plate 300 is lower than the lowest cloth roller 210, and the flat plate 300 is inclined along the inclined arrangement direction of the cloth roller 210. The material output from the roller cloth assembly 200 will fall onto the flat plate 300 or the right side of the flat plate 300. The flat plate 300 is lower than the lowest cloth roller 210 and is inclined along the inclined arrangement direction of the cloth roller 210, so that after the material is output from the cloth roller 210, it can fall directly onto the flat plate 300 or the trolley to its right. Without additional adjustment of the material conveying path, it can quickly enter the leveling stage, minimizing the interval time between cloth clothing and leveling, and avoiding the premature accumulation of material on the trolley surface to form irregular piles. In addition, the partial falling of material onto the flat plate 300 and then onto the trolley can also have a buffering effect on the falling material, reducing the splashing and dust caused by the high-speed falling of material from a height. The trolley moves to the left, and the scraping surface of the flat plate 300 forms an obtuse angle with the upper surface of the trolley. The flat plate 300 can use its own tilt angle to guide excess material to slide or roll on the scraping surface of the flat plate 300. Combined with the scraping action of the scraping end 310, the leveling process is smoother, reducing the impact and wear of the material on the flat plate 300. At the same time, it also reduces the accumulation and compression of the material by the flat plate 300, further improving the permeability of the material layer and providing better material layer conditions for the sintering process. By limiting the position and tilt direction relationship between the flat plate 300 and the material roller 210, the timeliness and effectiveness of the leveling operation are further optimized. If the flat plate 300 is tilted to the left from top to bottom, the scraping surface of the flat plate 300 will form an acute angle with the upper surface of the trolley. When scraping, excess material will be stuck in the acute angle space formed by the flat plate 300 and the material layer. The excess material will be piled up and squeezed instead of rolling upward along the surface of the flat plate 300. This will also increase the scraping resistance, causing impact wear on the flat plate 300, affecting the smoothness of the flat plate and the life of the equipment.

[0028] Reference Figure 3 In a further embodiment of the present invention, a rotating shaft 320 is provided at the upper end of the flat plate 300, and the rotating shaft 320 is rotatably mounted on the mounting frame 220 along its own axis. The rotational cooperation between the rotating shaft 320 and the mounting frame 220 ensures that the flat plate 300 can rotate smoothly around the axis of the rotating shaft 320 under the drive of the adjusting drive mechanism 400.

[0029] Reference Figure 4 In a further embodiment of the present invention, the mounting bracket 220 is provided with support seats 221 at both ends of the rotating shaft 320. The support seats 221 have through holes, and the two ends of the rotating shaft 320 extend into the through holes, with bearings 222 installed between the shaft and the inner wall of the through holes. The support seats 221 support the two ends of the rotating shaft 320; the bearings 222 reduce the frictional resistance between the rotating shaft 320 and the inner wall of the through holes in the support seats 221, making the rotation of the rotating shaft 320 smoother under the drive of the adjusting drive mechanism 400. By providing support seats 221 at both ends of the mounting bracket 220 corresponding to the rotating shaft 320, and installing bearings 222 between the through holes in the support seats 221 and the rotating shaft 320, the stability and flexibility of the rotation of the rotating shaft 320 are improved.

[0030] Reference Figure 3 In a further embodiment of the present invention, the mounting frame 220 is provided with an auxiliary support frame 223, which has an opening groove 224 with an opening on the right side. The rotating shaft 320 is embedded in the opening groove 224 in the middle, and the rotating shaft 320 and the opening groove 224 are in clearance fit. The auxiliary support frame 223 cooperates with the support base 221 to provide support from the middle and both ends of the rotating shaft 320, forming a multi-point support for the rotating shaft 320. This enhances the overall rigidity of the rotating shaft 320, and the weight and material impact load of the flat plate 300 can be partially distributed on the auxiliary support frame 223. This prevents the rotating shaft 320 from deforming in the middle during long-term rotation and material impact, ensuring that the flat plate 300 always remains horizontal and does not affect the flatness accuracy of the scraper end 310. At the same time, the clearance fit between the rotating shaft 320 and the opening groove 224 reduces the rotational resistance of the rotating shaft 320 while ensuring the support effect, and also facilitates installation. The combination of gap and semi-enclosed design reduces material accumulation and caking at that location.

[0031] Reference Figure 1In some embodiments of the present invention, one end of the mounting frame 220 is hinged to the frame 100, and the other end is connected to the frame 100 via a telescopic rod 600. One end of the telescopic rod 600 is hinged to the frame 100, and the other end is hinged to the mounting frame 220. By hinged one end of the mounting frame 220 to the frame 100 and connecting the other end to the frame 100 via the telescopic rod 600, the overall tilt angle of the roller-type fabric assembly 200 is adjustable. The overall tilt angle of the mounting frame 220 and the fabric roller 210 can be changed by adjusting the telescopic length of the telescopic rod 600 according to the particle size, humidity, and other characteristics of the material, thereby adjusting the material conveying speed and fabric thickness. This allows the equipment to adapt to different types of sintering materials, improving its versatility. Simultaneously, when maintenance of the fabric roller 210 is required, the angle of the mounting frame 220 can be adjusted via the telescopic rod 600, providing more convenient space for maintenance operations and reducing maintenance time.

[0032] Specifically, such as Figure 1 As shown, the telescopic rod 600 includes a main rod 610 and two connectors 620. The main rod 610 has threaded holes at both ends, and the two connectors 620 are threaded into the threaded holes at both ends of the main rod 610, allowing for telescopic adjustment through rotation. The two connectors 620 are hinged to the frame 100 and the mounting bracket 220, respectively. After installation, the threads at both ends of the main rod 610 are screwed in opposite directions, so that only rotating the main rod 610 is needed to extend or retract the two connectors 620.

[0033] Reference Figure 4 In some embodiments of the present invention, the adjustment drive mechanism 400 includes an adjustment motor 410, the output shaft of which is connected to the rotating shaft 320. The adjustment motor 410 is a rotary motor that drives the output shaft to rotate. The adjustment motor 410 provides a stable and controllable power source for the height adjustment of the flat material plate 300. The adjustment motor 410 can precisely control the rotation angle and speed of the output shaft according to the material layer thickness data detected by the layer thickness gauge, thereby driving the rotating shaft 320 to rotate, realizing the precise adjustment of the height of the scraping end 310 of the flat material plate 300, avoiding the error of manual adjustment, and ensuring that the flat material height matches the actual material layer thickness; at the same time, the driving mode of the adjustment motor 410 has a fast response speed and can adjust the flat material height in real time according to the changes in the material layer thickness.

[0034] Reference Figure 4 In a further embodiment of the invention, the output shaft 411 of the regulating motor 410 is connected to a reducer 420. The reducer 420 has an extended power shaft 421, which is connected to the rotating shaft 320 via a coupling 500. The reducer 420 may include a gear set and a worm gear to achieve speed reduction. The output shaft is connected to the power shaft 421 via the gear set and worm gear within the reducer 420. Figure 5 As shown, the reducer 420 includes a worm gear 422, a worm 424, and a first bevel gear 423. The power shaft 421 is connected to the worm gear 422 and can rotate synchronously. The worm gear 424 is connected to the first bevel gear 423 and can rotate synchronously. The output shaft 411 of the regulating motor 410 is provided with a second bevel gear 412, which meshes with the first bevel gear 423. Power transmission is achieved through the cooperation of the gear set and the worm gear. The worm gear transmission prevents power from being transmitted from the power shaft 421 to the motor and also has a self-locking function, ensuring that the flat plate 300 remains stable after rotating to a preset angle and height. Of course, in some other embodiments, the regulating motor 410 may also be a motor with a self-locking function, and the reducer 420 may only include a gear set, with transmission between the output shaft 411 and the power shaft 421 achieved solely through the gear set. The reducer 420 converts the high speed of the output shaft of the regulating motor 410 into the low speed and high torque output of the power shaft 421, ensuring that the rotating shaft 320 can obtain sufficient driving force to overcome the impact resistance of the material when driving the flat plate 300 to rotate, and avoiding jamming of the flat plate 300 due to insufficient power during the adjustment process; while the coupling 500 enables power transmission and compensates for the installation deviation between the rotating shaft 320 and the power shaft 421, ensuring the smoothness of power transmission, reducing equipment vibration and noise caused by shaft system deviation, extending the service life of the regulating motor 410 and the reducer 420, and improving the overall reliability of the equipment operation.

[0035] Reference Figure 6 In a further embodiment of the present invention, the reducer 420 has an outwardly extending manual adjustment shaft 425. Rotation of the manual adjustment shaft 425 drives the power shaft 421 to rotate; and torque can only be transmitted unidirectionally through the power shaft 421 or the output axis power shaft 421. The manual adjustment shaft 425 allows the operator to rotate the power shaft 421 to adjust the height of the leveling plate 300 in case of sudden events such as a malfunction of the adjusting motor 410 or a power outage, thus preventing interruption of sintering production due to equipment failure and improving the equipment's emergency handling capability. The fact that torque can only be transmitted unidirectionally through the power shaft 421 or the output axis power shaft 421 of the adjusting motor 410 prevents the reverse torque generated by material impacting the leveling plate 300 during leveling from being transmitted to the adjusting motor 410, protecting the adjusting motor 410 from damage, and also preventing material impacting the leveling plate 300 from causing instability in its position due to rotation, thus improving the safety and stability of equipment operation. Specifically, as shown... Figure 7 As shown, in Figure 5Based on this, a third bevel gear 426 is provided at the bottom of the manual adjustment shaft 425. The third bevel gear 426 is connected to the second bevel gear 412 for transmission. Thus, when the motor is not outputting power, the power shaft 421 can be rotated by rotating the manual adjustment shaft 425, thereby adjusting the angle and height of the flat plate 300.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
