Description

Technical Field

[0001] This utility model relates to the field of coal grate technology, specifically to an anti-clogging vibrating coal grate. Background Technology

[0002] Coal grates, widely used in coal mines, coal washing plants, and other similar locations, are essential for coal screening, filtration, and transport. They effectively separate impurities from coal, improving its purity while ensuring smooth transport.

[0003] To prevent coal from clogging, existing coal grates use vibration to screen the coal, causing it to detach during vibration and thus preventing the grate holes from becoming blocked. However, some coal is sticky and may adhere to the grate over time, potentially clogging it. Vibration alone is insufficient to remove this clogging, thus affecting subsequent screening and filtration efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging vibrating coal grate, which solves the problem mentioned in the background art that some coal is sticky and will adhere to the coal grate, which may clog the coal grate over time, and it is difficult to clean it by vibration alone, thus affecting the subsequent screening and filtration efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging vibrating coal grate, comprising a support frame, a coal grate body, a movable frame, and a horizontal plate. The support frame has side grooves on both its front and rear side walls, and a threaded rod is rotatably connected between the left and right inner walls of one of the side grooves. The bottom ends of the movable frame are located inside the front and rear side grooves, respectively, and the threaded rod passes through the movable frame and is threadedly connected to it. An electric push rod is fixedly connected to the center of the top of the movable frame, and the bottom telescopic end of the electric push rod passes through the surface of the movable frame and is fixedly connected to the horizontal plate. Several insert blocks are uniformly fixedly connected to the bottom of the horizontal plate. Limiting grooves are uniformly opened at the bottom edge of the side groove below the threaded rod, and a telescopic groove is opened on the side wall of the movable frame on one side of the threaded rod. The bottom of the telescopic groove communicates with the outside. An adjusting block is vertically slidably connected to the inner side of the telescopic groove, and a return spring is fixedly connected between the top of the adjusting block and the top of the telescopic groove. A limiting block is fixedly connected to the bottom of the adjusting block.

[0006] In this technical solution, the servo motor starts and drives the threaded rod to rotate, causing the moving frame to move laterally. The electric push rod starts and extends downward, driving the horizontal plate and the insert block to move downward. The insert block is inserted into the screen holes of the coal grate body. During the insertion process, the coal that is attached and blocking it is scraped off, avoiding the impact of blockage on subsequent coal screening and ensuring the normal use of the coal grate body. When the moving frame 7 moves to the limiting groove, the limiting block is inserted into the limiting groove. At this time, the insert block will be exactly aligned with the coal grate body below, and the moving frame will remain stable, avoiding insertion failure due to misalignment during the insertion process, thus improving the working efficiency of the device.

[0007] Preferably, the insert block corresponds one-to-one with the screen holes of the coal grate body below, and the size of the insert block and the screen holes of the coal grate body are the same.

[0008] Preferably, the limiting groove fits into the limiting block, and the number of limiting grooves is consistent with the number of vertically arranged screen holes of the coal grate body.

[0009] Preferably, a servo motor is fixedly connected to the right side wall of the support frame at the horizontal position of the threaded rod, and the outer end of the drive shaft of the servo motor is fixedly connected to one end of the threaded rod.

[0010] Preferably, the front and rear inner walls of the movable frame are provided with constraint grooves, and the two end protrusions of the horizontal plate are located inside the constraint grooves on both sides and are vertically slidably connected inside the constraint grooves.

[0011] Preferably, a vibration motor is fixedly connected to both the left and right sides of the top of the coal grate body, the coal grate body is located at the top center of the support frame, and a number of vibration springs are connected between the bottom edge of the coal grate body and the support frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a movable frame, electric push rod, horizontal plate, and insert block to clean the screen holes of the coal grate body. The servo motor starts and drives the threaded rod to rotate, causing the movable frame to move laterally. The electric push rod starts and extends downward, driving the horizontal plate and insert block to move downward. The insert block is inserted into the screen holes of the coal grate body. During the insertion process, the coal that is attached and blocking it is scraped off, avoiding the impact of blockage on subsequent coal screening and ensuring the normal use of the coal grate body.

[0014] 2. This utility model facilitates the insertion of the insert block through the limiting groove and the limiting block. When the insert block is moved to the limiting groove, it is inserted into the limiting groove. At this time, the insert block will be aligned with the coal grate body below, and the moving frame will remain stable. This avoids insertion failure due to misalignment during the insertion process and improves the working efficiency of the device. Attached Figure Description

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0021] A type of anti-clogging vibrating coal grate, see [link / reference] Figures 1 to 3 The system includes a support frame 1, a coal grate body 2, a movable frame 7, and a horizontal plate 9. The front and rear side walls of the support frame 1 are provided with side grooves 4, and a threaded rod 5 is rotatably connected between the left and right inner walls of one of the side grooves 4 of the support frame 1. The bottom ends of the movable frame 7 are located inside the front and rear side grooves 4, and the threaded rod 5 passes through the movable frame 7 and is threadedly connected to the movable frame 7. An electric push rod 8 is fixedly connected to the center of the top of the movable frame 7. The bottom telescopic end of the electric push rod 8 passes through the surface of the movable frame 7 and is fixedly connected to the horizontal plate 9. Several insert blocks 10 are evenly fixedly connected to the bottom of the horizontal plate 9. When the electric push rod 8 is activated, it extends downward, driving the horizontal plate 9 and the insert blocks 10 to move downward. The insert blocks 10 are inserted into the screen holes of the coal grate body 2. During the insertion process, the coal attached to and blocking the grate is scraped off, avoiding the impact of blockage on subsequent coal screening.

[0022] Limiting grooves 6 are evenly provided at the bottom edge of the side groove 4 below the threaded rod 5, and a telescopic groove 11 is provided on the side wall of the movable frame 7 on one side of the threaded rod 5. The bottom of the telescopic groove 11 is connected to the outside. An adjusting block 13 is vertically slidably connected to the inner side of the telescopic groove 11, and a return spring 12 is fixedly connected between the top of the adjusting block 13 and the top of the inner side of the telescopic groove 11. A limiting block 14 is fixedly connected to the bottom of the adjusting block 13. When the movable frame 7 moves to the limiting groove 6, the limiting block 14 is inserted into the limiting groove 6. At this time, the insert 10 will be aligned with the coal grate body 2 below, and the movable frame 7 will remain stable, which facilitates the accurate insertion of the insert 10.

[0023] Specifically, such as Figure 2 As shown, the insert 10 corresponds one-to-one with the screen holes of the coal grate body 2 below, and the size of the insert 10 and the screen holes of the coal grate body 2 are the same. Therefore, the coal in the screen holes will be scraped off during the insertion of the insert 10.

[0024] It is worth noting that, such as Figure 1 and Figure 3 As shown, the limiting groove 6 fits into the limiting block 14, and the number of limiting grooves 6 is consistent with the number of vertical rows of screen holes in the main body of the coal grate 2. Therefore, during the movement of the moving frame 7, whenever the limiting block 14 is inserted into the limiting groove 6, the insert block 10 will correspond to the current vertical row of screen holes, which facilitates accurate insertion.

[0025] It is worth noting that, such as Figure 1 As shown, a servo motor 501 is fixedly connected to the right side wall of the support frame 1 at the horizontal position of the threaded rod 5. The outer end of the drive shaft of the servo motor 501 is fixedly connected to one end of the threaded rod 5. After the servo motor 501 is started, it drives the threaded rod 5 to rotate, thereby moving the moving frame 7 along the side groove 4.

[0026] It is worth noting that, such as Figure 2 As shown, the front and rear inner walls of the movable frame 7 are provided with constraint grooves 901. The two ends of the horizontal plate 9 are respectively located inside the constraint grooves 901 on both sides and are vertically slidably connected inside the constraint grooves 901. The constraint grooves 901 can keep the horizontal plate 9 stable during the lifting and lowering process, so that the insert block 10 can be accurately inserted into the screen hole. During the insertion process, the coal grate body 2 will be squeezed downward together, but it does not affect the normal scraping of the screen hole by the insert block 10.

[0027] It is worth noting that, such as Figure 1 and Figure 2 As shown, vibration motors 3 are fixedly connected to the top left and right sides of the coal grate body 2. The coal grate body 2 is located at the top center of the support frame 1, and several vibration springs 201 are connected between the bottom edge of the coal grate body 2 and the support frame 1. During the vibration of the vibration motors 3, the entire coal grate body 2 vibrates together, thereby screening the coal.

[0028] In actual use, the servo motor 501 starts and drives the threaded rod 5 to rotate, causing the moving frame 7 to move laterally. The electric push rod 8 starts and extends downward, driving the horizontal plate 9 and the insert block 10 to move downward. The insert block 10 is inserted into the screen holes of the coal grate body 2. During the insertion process, the coal that is attached and blocked is scraped off, avoiding the impact of blockage on subsequent coal screening and ensuring the normal use of the coal grate body 2. When the moving frame 7 moves to the limiting groove 6, the limiting block 14 is inserted into the limiting groove 6. At this time, the insert block 10 will be aligned with the coal grate body 2 below, and the moving frame 7 will remain stable, avoiding insertion failure due to misalignment during the insertion process, thus improving the working efficiency of the device. After the current vertical row of screen holes is cleaned, the adjusting block 13 is lifted upward, causing the limiting block 14 to slide out of the limiting groove 6. At this time, the moving frame 7 can continue to slide and move to the next limiting groove 6 to continue the operation.
