Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically a wear-resistant device for the scraper plate of a mining disc feeder. Background Technology

[0002] In existing technologies, disc feeders are widely used in mining, suitable for feeding granular materials (≤Φ30mm). Disc feeders work by rotating a disc at the bottom. Material spirals downwards inside the feeder sleeve and is then scraped off onto the conveyor belt at the discharge port by a scraper. The scraper is made of Q235 steel plate and welded to the edge of the discharge port. During continuous operation, the scraper is in direct contact with the material. Because it is made of ordinary steel plate, it wears quickly and thins rapidly, requiring frequent replacement. Furthermore, if the contact area between the scraper bottom and the disc becomes severely worn and the gap becomes too large, unscraped material will remain on the disc and rotate with it, wearing down the sleeve. Material can also fall from the disc into the conveyor belt interlayer, causing belt misalignment and scratches. Utility Model Content

[0003] The purpose of this invention is to provide a wear-resistant device for scraper plates of mining disc feeders that is simple in structure, has a long service life, and performs well, in order to address the above-mentioned shortcomings.

[0004] The technical solution of this utility model is: a wear-resistant device for the scraper plate of a mining disc feeder, including the scraper plate of the disc feeder. A wear-resistant layer of a certain thickness is deposited on the surface of the scraper plate with wear-resistant welding rods. A flat box with an open top is provided on the back of the scraper plate. Multiple filling boxes are longitudinally separated by multiple partitions inside the flat box. Each filling box is embedded with a magnetic block, and a set screw for fixing the magnetic block acts on it.

[0005] The above scheme also includes:

[0006] The magnetic block has a horizontally placed pressure plate on top, and a downward-acting set screw is connected in the middle of the pressure plate.

[0007] The wear-resistant layer is 5mm thick, and its height should be 50mm greater than the material piled up on the scraper surface.

[0008] There are eight filling boxes.

[0009] A wear-resistant device for the scraper plate of a mining disc feeder includes a self-made wear-resistant plate and a filling box. Its distinguishing feature is that the filling box is inlaid with magnetic blocks.

[0010] The self-made wear-resistant plate is made by depositing a 5mm high wear-resistant layer on the surface of the scraper plate using wear-resistant welding rods.

[0011] The filling box is an open design with a longitudinal partition inside for embedding magnetic blocks, and there are top screws above the magnetic blocks.

[0012] The size of the partition can be determined according to the size of the embedded magnet.

[0013] The advantages of this invention are: 1. A magnetic block is embedded on the back of the scraper plate. Due to the magnetic effect of the magnetic block, fine materials are adsorbed on the surface of the scraper plate and form a material layer. Therefore, during the operation of the disc feeder, the material will not wear down the scraper plate. Furthermore, the magnetic block can be adjusted downwards according to the wear condition of the base plate to ensure a normal gap between the scraper plate and the disc, preventing material from falling off the disc. It can be applied to different models of disc feeders, and the wear-resistant device for the scraper plate can be made according to the size of the discharge port. 2. A wear-resistant layer of a certain thickness is deposited on the surface of the scraper plate with wear-resistant welding rods, which can significantly improve the wear resistance of the scraper plate. 3. It can be prefabricated and welded and installed when the disc feeder is stopped. 4. The structure is simple and reasonable, easy to install, reduces the labor intensity of on-site maintenance personnel, improves work efficiency, and reduces the frequency of equipment maintenance.

[0014] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0015] Figure 1 This is a simplified structural diagram of the present invention.

[0016] Figure 2 yes Figure 1 Simplified diagram of the left-side view structure. Detailed Implementation

[0017] See Figure 1 , 2 The component names are as follows: scraper 1, wear-resistant layer 2, back plate 3, partition 4, magnet 5, bottom plate 6, filling box 7, pressure plate 8, set screw 9.

[0018] See Figure 1 , 2The wear-resistant device for the scraper plate of a mining disc feeder includes a scraper plate 1. A wear-resistant layer 2 of a certain thickness, 5mm, is deposited on the surface of the scraper plate 1 using EDZCr-B-0A type wear-resistant welding rods. The height of the wear-resistant layer 2 is 50mm greater than the material accumulation height on the surface of the scraper plate 1. A flat box with an open top is provided on the back of the scraper plate 1. The flat box consists of the scraper plate 1, a back plate 3, a bottom plate 6, and side plates. Inside the flat box, eight spaced-apart filling boxes 7 are separated longitudinally by seven partitions 4. Each filling box 7 contains a magnetic block 5. A horizontally placed pressure plate 8 is positioned above the magnetic block 5, and a downward-acting set screw 9 is connected to the center of the pressure plate 8. An M16 screw hole is tapped in the center of the pressure plate 8, and the magnetic block 5 is held in place by the eight M16 set screws 9. The magnetic block 5 rests on the bottom plate 6. The main issue is that after the bottom plate 6 of the filling box 7 wears down, the gap between it and the disc will increase. At this time, the top screw 9 installed on the pressure plate 8 above the magnetic block 5 can be adjusted downward to make the magnetic block 5 move down, which can make up for the gap and prevent the disc from falling off. At the same time, it can also prevent the magnetic block 5 from moving upward, thus playing a limiting role.

[0019] During the operation of the disc feeder, as the disc rotates, the ore moves downwards within the feeder sleeve to the discharge port. Due to the magnetic effect of the magnetic block 5, some fine materials are adsorbed onto the surface of the wear-resistant layer 2, forming a material layer. When the material at the discharge port is scraped off by the scraper plate 1, only the material layer adsorbed on the surface of the wear-resistant layer 2 is worn away, thus protecting the wear-resistant layer 2 and the scraper plate 1 from wear. When the bottom plate 6 wears down, causing an increase in the gap between the bottom of the filling box and the disc, the adjusting screw 9 moves the magnetic block 5 downwards to ensure a normal gap and prevent material from falling off the disc.

[0020] The above description is merely a specific embodiment of this utility model, and the various examples do not constitute a limitation on the substantive content of this utility model.
