Description

Technical Field

[0001] This utility model belongs to the field of anti-clogging technology of grate bars, and in particular relates to a novel grate bar vibrator. Background Technology

[0002] The grate is a key component on the sintering machine trolley. Its main function is to form a trough-shaped space with the trolley sideboard to accommodate and support the ore. The upper surface of the grate is in contact with the ore, and its two upper ends bear the force, thus providing support. The bottom of the grate fixes the grate during unloading to prevent it from falling off, and it also provides support when the top of the grate is under pressure, effectively preventing the grate from bending.

[0003] In the steel production sector, clogging of sintering machine grate bars is a common problem. Currently, many steel plants have severe clogging of sintering machine grate bars, with clogging levels typically ranging from 10% to 40%. This affects the quality and output of sintered ore to some extent. The traditional method is manual cleaning, which is not only inefficient but also makes it difficult to maintain the continuity and stability of the sintering process. Utility Model Content

[0004] The purpose of this invention is to address the problems of low efficiency and difficulty in maintaining the continuity and stability of the sintering process caused by the existing manual cleaning method, and to propose a new type of grate bar vibrator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel grate vibrator includes a support plate and a base. The bottom of the support plate is connected to multiple legs, the top of the support plate is provided with a transmission mechanism, the top of the base is provided with a striking mechanism, and one side of the base is provided with a stop mechanism.

[0007] The striking mechanism includes multiple hinge seats, the bottom of which is connected to the top of the base. A hinge block is hinged to one side of the hinge seat, a vibrating arm is connected to the top of the hinge block, a vibrating head is connected to the top of the vibrating arm, a slider is connected to the bottom of the vibrating arm, and a counterweight sleeve is connected to the outer wall of the vibrating arm.

[0008] As a further description of the above technical solution:

[0009] The transmission mechanism includes two first fixed sleeves. The bottom of the first fixed sleeve is connected to the top of the support plate. A connecting rod is rotatably connected to the inner wall of the first fixed sleeve, and the two connecting rods are connected to the same rotating shaft. The outer wall of the rotating shaft is connected to multiple rows of teeth, and the side of the multiple rows of teeth near the slider is in contact with the bottom of the slider. A motor is connected to the top of the support plate, and the output shaft of the motor is connected to one end of one of the connecting rods.

[0010] As a further description of the above technical solution:

[0011] The following mechanism includes a second fixed sleeve, one side of which is connected to one side of the base. A rotating rod is rotatably connected to the inner wall of the second fixed sleeve. One end of the rotating rod extends to the outside of the inner wall of the second fixed sleeve, and the other end of the rotating rod is rotatably connected to a fixed block. One side of the fixed block is connected to one side of the base.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the rotating rod is connected to multiple cams, and the outer wall of the rotating rod is connected to a handle. One end of the handle has a groove, and the outer wall of the rotating rod has a sliding groove. A sliding block is slidably connected to the inner wall of the sliding groove. The outer wall of the sliding block fits against the inner wall of the groove. An internal toothed ring is connected to one side of the second fixed sleeve.

[0014] As a further description of the above technical solution:

[0015] The bottom of the sliding block is connected to two springs, the other end of which is connected to the inner wall of the groove. The top of the sliding block is connected to a toothed block, one side of which meshes with one side of the inner toothed ring.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the groove is provided with a movable groove, and a movable rod is slidably connected to the inner wall of the movable groove. One end of the movable rod is connected to the top of the sliding block, and the other end of the movable rod extends out of the movable groove and is connected to a button.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, by setting a striking mechanism and a transmission mechanism, the rotation of the motor output shaft drives the rotating shaft and multiple toothed pinions to rotate, thereby enabling the slider to drive the tail of the vibrating arm to rise and the vibrating head to fall. When the slider disengages from the toothed pinions, the weight of the counterweight sleeve and the tail of the vibrating arm can drive the vibrating head to rise, allowing the vibrating head to strike the grate bars, thereby cleaning the accumulated material on the grate bars and preventing excessive accumulation of material from clogging the grate bars. This method avoids the need to use a large amount of manpower to clean the accumulated material between the grate bars, thereby saving labor and improving the efficiency of material cleaning.

[0020] 2. In this utility model, by setting a stop mechanism, pressing the button drives the moving rod and sliding block to move, thereby causing the toothed block to separate from the inner toothed ring. By pulling the handle, the rotating rod and multiple cams rotate, thereby causing the slider to separate from the toothed strip and rise beyond the maximum stroke of the toothed strip. Thus, the vibrating head can stop striking the grate bar without stopping the rotation of the shaft. In this way, it can be turned off and used at any time without affecting the use of other machines, effectively saving energy and improving energy utilization. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 This utility model provides a technical solution: a novel grate vibrator, including a support plate 1 and a base 6. The bottom of the support plate 1 is connected to multiple legs 2, the top of the support plate 1 is provided with a transmission mechanism 3, the top of the base 6 is provided with a striking mechanism 5, and the side of the base 6 is provided with a stop mechanism 4.

[0030] The striking mechanism 5 includes multiple hinge seats 504. The bottom of the hinge seat 504 is connected to the top of the base 6. A hinge block 505 is hinged to one side of the hinge seat 504. A vibrating arm 503 is connected to the top of the hinge block 505. A vibrating head 506 is connected to the top of the vibrating arm 503. A slider 502 is connected to the bottom of the vibrating arm 503. A counterweight sleeve 501 is connected to the outer wall of the vibrating arm 503. The transmission mechanism 3 includes two first fixed sleeves 303. The bottom of the first fixed sleeve 303 is connected to the top of the support plate 1. A connecting rod 301 is rotatably connected to the inner wall of the first fixed sleeve 303. The two connecting rods 301 are connected to the same rotating shaft 304. Multiple teeth 305 are connected to the outer wall of the rotating shaft 304. One side of the teeth 305 near the slider 502 is in contact with the bottom of the slider 502. A motor 302 is connected to the top of the support plate 1. The output shaft of the motor 302 is connected to one end of one of the connecting rods 301.

[0031] The specific implementation method is as follows: The rotation of the output shaft of the motor 302 drives the connecting rod 301 connected to the output shaft of the motor 302 to rotate, thereby driving the rotating shaft 304 to rotate. The rotation of the rotating shaft 304 drives the multiple gears 305 on the rotating shaft 304 to rotate. When the gears 305 rotate, they can push the bottom of the slider 502 through the arc side, so that the slider 502 can drive the vibrating arm 503 to move. And through the hinge block 505, the vibrating arm 503 can rotate around the hinge seat 504, thereby driving the vibrating head 506 to descend and the tail of the vibrating arm 503 to rise. When the slider 502 at the tail of the vibrating arm 503 disengages from the gears 305, the counterweight sleeve 501 and the gravity at the tail of the vibrating arm 503 can... The vibrating arm 503 can rotate in the opposite direction, thereby driving the vibrating head 506 to rise. This allows the vibrating head 506 to strike the grate bars with a certain force, thus clearing the accumulated material on the grate bars and preventing excessive accumulation that could clog them. This method avoids the need for a large amount of manpower to specifically clean the accumulated material between the grate bars, saving labor and improving the efficiency of material removal. Because the adjacent teeth 305 are arranged in a certain pattern, the vibrating head 506 can strike the grate bars in a certain pattern. The vibrating arm 503 utilizes the lever principle to calculate the force of the vibrating head 506 striking the grate bars, converting the direct mechanical force into indirect force and avoiding damage to the grate bars.

[0032] The following mechanism 4 includes a second fixed sleeve 403. One side of the second fixed sleeve 403 is connected to one side of the base 6. A rotating rod 402 is rotatably connected to the inner wall of the second fixed sleeve 403. One end of the rotating rod 402 extends to the outside of the inner wall of the second fixed sleeve 403, and the other end of the rotating rod 402 is rotatably connected to a fixed block 409. One side of the fixed block 409 is connected to one side of the base 6. Multiple cams 401 are connected to the outer wall of the rotating rod 402. A handle 404 is connected to the outer wall of the rotating rod 402. A groove 413 is provided at one end of the handle 404. A sliding groove 407 is provided on the outer wall of the rotating rod 402. A sliding block is slidably connected to the inner wall of the sliding groove 407. 408, the outer wall of the sliding block 408 fits against the inner wall of the groove 413, one side of the second fixed sleeve 403 is connected to an inner toothed ring 405, the bottom of the sliding block 408 is connected to two springs 406, the other end of the springs 406 is connected to the inner wall of the slide groove 407, the top of the sliding block 408 is connected to a toothed block 410, one side of the toothed block 410 meshes with one side of the inner toothed ring 405, the inner wall of the groove 413 is provided with a moving groove 414, the inner wall of the moving groove 414 is slidably connected to a moving rod 411, one end of the moving rod 411 is connected to the top of the sliding block 408, and the other end of the moving rod 411 extends to the outside of the moving groove 414 and is connected to a button 412.

[0033] The specific implementation method is as follows: Since the connecting rod 301 connected to the end of the rotating shaft 304 away from the motor 302 is connected to the transmission components of other machines, the rotating shaft 304 drives the vibrating head 506 to strike the grate bar while also driving other machines to operate. By pressing the button 412, the moving rod 411 moves within the moving groove 414. The movement of the moving rod 411 causes the sliding block 408 to compress the spring 406, causing the spring 406 to compress and generate elastic force. At the same time, it can drive the toothed block 410 to separate from the internal toothed ring 405, thereby allowing the rotating rod 402 to rotate. By pulling the handle 404, the rotating rod 402 rotates. The rotation of the rotating rod 402 drives multiple cams 401 to rotate, allowing the cams 401 to interact with the vibrating head 506. The bottom of arm 503 contacts and can push the tail of the vibrating arm 503 upward through compression, causing the slider 502 to separate from the toothed bar 305 and rise beyond the maximum stroke of the toothed bar 305. This allows the vibrating head 506 to stop striking the grate bar without stopping the rotation of the rotating shaft 304. This allows the machine to be turned off and used at any time without affecting the use of other machines, effectively saving energy and improving energy utilization. When the button 412 is released, the compressed spring 406 releases its elasticity and drives the sliding block 408 to return to its original position. This allows the toothed block 410 to mesh with the internal toothed ring 405, thereby limiting the rotation of the rotating rod 402 and allowing the cam 401 to maintain support for the vibrating arm 503.

[0034] Working principle: When in use, the motor 302 is started. The output shaft of the motor 302 rotates, driving the connecting rod 301 and the rotating shaft 304 connected to the output shaft of the motor 302 to rotate. This, in turn, drives the multiple gears 305 on the rotating shaft 304 to rotate. When the gears 305 rotate, they push the slider 502 through one side of the arc surface, thereby causing the vibrating arm 503 to rotate around the hinge seat 504 via the hinge block 505. This causes the tail of the vibrating arm 503 to rise, simultaneously causing the vibrating head 506 to descend. When the slider 502 at the tail of the vibrating arm 503 disengages from the gears 305, under the action of the counterweight sleeve 501 and the gravity of the tail of the vibrating arm 503, it can drive the vibrating head 506 to descend. The vibrating head 506 rises and strikes the grate bars to clean up the accumulated material on them. Pressing button 412 moves the moving rod 411 and sliding block 408, causing the toothed block 410 to separate from the inner toothed ring 405. Then, pulling handle 404 drives the rotating rod 402 and multiple cams 401 to rotate, causing the cams 401 to drive the tail of the vibrating arm 503 to rise, causing the slider 502 to separate from the toothed rack 305 and rise beyond the maximum stroke of the toothed rack 305. This allows the vibrating head 506 to stop striking the grate bars without stopping the rotation of the rotating shaft 304, thus enabling it to be turned off and used at any time without affecting the use of other machines.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
