Description

Technical Field

[0001] This utility model relates to the field of feeding and metering equipment technology, specifically to a wear-resistant screw feeder for mining. Background Technology

[0002] The screw feeder weighing scale is an automated device that integrates continuous conveying and precise metering. Its core is to convey materials through a screw conveyor structure and combine weighing and speed measurement modules to calculate the material flow rate in real time. It can also automatically adjust to stabilize the feeding rate and is widely applicable to various industrial scenarios.

[0003] Mining materials are generally hard and contain a large number of sharp particles. When they are fed by a screw feeder, they will cause continuous abrasion to the key components of the equipment. The screw blades are constantly rubbed against the high-hardness stones, and the edges and roots of the blades are easily worn and thinned, resulting in a decrease in conveying efficiency. Utility Model Content

[0018] The wear-resistant component is installed on the top surface of the feeding and weighing scale body 1 to reduce the wear of the screw rod 2. The wear-resistant component includes a feed inlet 5, which is located on the top surface of the feeding and weighing scale body 1. A feed hopper 6 is fixedly sleeved inside the feed inlet 5. Fixing plates 10 are fixedly installed on both sides of the inside of the feed hopper 6. A buffer plate 11 is fixedly installed on one side of the fixing plate 10. A screen plate 8 is movably sleeved inside the feed hopper 6. Several screen openings 20 are opened on the top surface of the screen plate 8. A locking block 9 is fixedly installed on both sides of the screen plate 8. A connecting port 7 is opened on both sides of the feed hopper 6. The connecting port 7 is movably sleeved with the locking block 9.

[0019] When feeding ore blocks, the ore blocks are poured into the feed hopper 6. The screen plate 8 in the feed hopper 6 can screen the ore blocks, allowing small pieces of ore to fall through the screen opening 20 into the inside of the feeding weighing body 1. Before falling into the feeding weighing body 1, the ore will fall onto the buffer plate 11 in the feed hopper 6. The inclined design of the buffer plate 11 can buffer the falling ore and prevent the ore from directly hitting the screw rod 2 inside the feeding weighing body 1, which would easily cause wear on the screw rod 2. Screening the ore before feeding can prevent large pieces of ore with high hardness from entering the feeding weighing body 1 and wearing down the screw rod 2. After that, the ore can be conveyed through the screw rod 2 to the discharge port 3 for discharge, which improves the wear resistance of the spiral blades on the screw rod 2 and reduces the wear of the screw rod 2. Example 2

[0020] refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6Based on Embodiment 1 above, in the wear-resistant mining-specific screw feeder weighing scale described in this embodiment, a support frame 14 is provided on the bottom surface of the feeder weighing scale body 1. Two base plates 15 are fixedly installed on the bottom surface of the support frame 14, and mounting plates 16 are fixedly installed on both sides of the support frame 14. By providing the support frame 14, the feeder weighing scale body 1 can be placed on the support frame 14 during use, so that the support frame 14 and the base plates 15 support the feeder weighing scale body 1, facilitating the feeding of ore.

[0021] Two mounting blocks 17 are fixedly installed on both sides of the feeding weighing scale body 1. Threaded holes 18 are provided on one side of each mounting block 17 and one side of each mounting plate 16. Threaded rods 19 are threaded onto the inner circular wall of each threaded hole 18. By using the threaded rods 19, when the feeding weighing scale body 1 is placed on the support frame 14, the threaded rods 19 can secure the feeding weighing scale body 1 to the mounting plate 16 on the support frame 14, preventing the feeding weighing scale body 1 from shaking on the support frame 14 during ore feeding.

[0022] First support plates 12 are fixedly installed on both sides of the inside of the feed hopper 6. One side of the first support plate 12 is fixedly installed on one side of the buffer plate 11. By setting the first support plate 12, the first support plate 12 can support the buffer plate 11, preventing the buffer plate 11 from being easily damaged by a large amount of ore falling on it for a long time. A rubber layer 13 is fixedly installed on one side of the buffer plate 11. By setting the rubber layer 13, the rubber layer 13 can buffer the force falling on the buffer plate 11, reducing the wear caused by the impact of ore on the surface of the buffer plate 11. Discharge plates 4 are fixedly installed on both sides of the inside of the discharge port 3, so that the ore can be buffered and discharged from the discharge port 3 through the discharge plates 4. Two second support plates 21 are fixedly installed on one side of the inside of the feed hopper 6. The second support plates 21 can support the screen plate 8, preventing the screen plate 8 from easily overturning inside the feed hopper 6 after the ore falls on it. The spiral blades of the screw rod 2 are made of wear-resistant alloy steel plate, which has the characteristics of high hardness and wear resistance.

[0023] refer to Figures 1-6As shown, the working principle of this utility model is as follows: When feeding ore blocks, the ore blocks are poured into the feed hopper 6. The screen plate 8 in the feed hopper 6 can screen the ore blocks, so that small pieces of ore fall through the screen opening 20 into the interior of the feeding weighing body 1. Before falling into the feeding weighing body 1, the ore will fall on the buffer plate 11 in the feed hopper 6. The inclined design of the buffer plate 11 can buffer the falling ore and prevent the ore from directly hitting the screw rod 2 in the feeding weighing body 1, which would easily cause wear on the screw rod 2. Screening the ore before feeding can prevent large pieces of ore with high hardness from entering the feeding weighing body 1 and wearing down the screw rod 2. Then the ore can be conveyed through the screw rod 2 to the discharge port 3 for discharge, which improves the wear resistance of the spiral blades on the screw rod 2 and reduces the wear of the screw rod 2.
