TECHNICAL FIELD
[0001] The utility model relates to mine equipment technical field, namely mine grading process vibrating screen ore feeding device. BACKGROUND
[0002] In the prior art, the classification operation plays a vital role in the mine wet type beneficiation process production, and various classification equipment is important beneficiation equipment for separating different particle sizes according to production needs. The linear vibrating screen is widely used due to its large vibration amplitude, good screening effect, and low requirement for operation space. However, in actual production application, there are many factors that affect the classification operation efficiency and screening effect of the linear vibrating screen. The concentration of the material entering the screen can be adjusted in the beneficiation process, while the flow rate and distribution of the material entering the screen need to be modified according to the actual production conditions and environment to ensure the optimal working effect of the linear vibrating screen and obtain the required particle size for the beneficiation process.
[0003] From the current use of linear vibrating screens in mine classification processes, it can be seen that since the equipment is not equipped with standard ore collection and distribution devices when it leaves the factory, the application units design the devices themselves during installation, which makes it impossible to ensure the appropriate flow rate and uniform distribution of the material entering the screen of most linear vibrating screens. Either the flow rate is too fast, causing excessive impact and friction on the screen surface, or the distribution of the material entering the screen is uneven, the effective working area of the screen surface is too small, the screening effect is poor, and the required particle size cannot be fully separated, resulting in some qualified particle sizes returning to the beneficiation process, causing high process load, reducing the process throughput, reducing the output of finished products, and increasing the cost of the beneficiation process.

[0012] Figure 1 is the structural diagram of the utility model.
[0013] Figure 2 is the structural diagram of the display opening part. DETAILED DESCRIPTION
[0014] Referring to Figure 1 , 2 , the names of the parts are as follows: ore feeding groove 1, ore collecting box 2, partition 3, opening 4, distributor 5, inclined discharge weir plate 6, bolt 7, butter pad 8, wear-resistant rubber 9, folding leaf 10, pull rod 11, magnetic lining plate 12, discharge hole 13, feeding area 14, buffer area 15.
[0015] Referring to Figure 1 , 2 , the mine grading process vibrating screen ore feeding device comprises an upper open ore collecting box 2, the lower right side of the ore collecting box 2 is connected with a distributor 5, 12 M20 bolts 7 are used to connect the distributor 5 together, and a butter pad 8 is clamped in the opening 4 (see Figure 2). The ore collecting box 2 and the distributor 5 are bolted together. It is convenient for the distributor 5 to be maintained and replaced in the future, and the distributor 5 is convenient to disassemble and separate when the distributor 5 hinders the maintenance of the linear vibrating screen. The partition plate 3 in the ore collecting box 2 divides the ore collecting box 2 into the feeding area 14 and the buffer area 15, and is used to reduce the too high flow rate of the ore caused by the process drop. The lower side of the distributor 5 is provided with the discharge hole 13 connected with the vibrating screen, and the discharge hole 13 is 500 mm away from the bottom of the distributor 5. The outer edge of the discharge hole 13 is provided with the inclined discharge weir plate 6 connected with the folding leaf 10, the inclined discharge weir plate 6 is paved with the wear-resistant rubber 9, the back of the inclined discharge weir plate 6 is provided with the pull rod 11 for adjusting the slope of the inclined discharge weir plate 6, the slope angle of the inclined discharge weir plate 6 can be manually adjusted through the pull rod 11 according to the ore properties and the feeding amount, and the suitable ore flow rate and the uniform ore distribution can be obtained. The inner walls of the ore collecting box 2 and the distributor 5 are pasted with the magnetic lining plate 12 for improving the wear resistance of the inner walls. The magnetic lining plate 12 is a kind of lining plate filled with magnetic blocks, is usually applied to the ball mill of the mine grinding equipment, and is mostly the secondary grinding ball mill. The magnetic lining plate is used to protect the inner wall of the ball mill from being worn. Due to the magnetic effect of the magnetic blocks, the magnetic particles in the material are adsorbed on the surface of the lining plate to form an ore layer, so that the wear of the surface of the lining plate in the grinding process is reduced or avoided. The wear resistance of the magnetic lining plate is 3-5 times higher than that of the manganese steel lining plate and 8-10 times higher than that of the ordinary steel plate. Therefore, the magnetic lining plate is widely applied in the magnetite grinding and separating process. In view of the high wear resistance of the magnetic lining plate, the magnetic lining plate is pasted on the inner walls of the ore collecting box 1 and the distributor 5 in the device to improve the wear resistance.
[0016] During the classification process by using the linear vibrating screen, the flow rate and the uniform degree of the wet ore feeding directly affect the screening effect of the linear vibrating screen. The height of the partition plate 3 and the discharge hole 13 in the ore collecting box 2 can greatly reduce the flow rate of the ore, and the inclined discharge weir plate 6 with the adjustable slope can further adjust the flow rate of the ore and plays an extremely important role in the uniform distribution of the ore.
[0017] During the working process of the linear vibrating screen, the wet ore enters the feeding area 14 of the ore collecting box 2 from the ore feeding groove 1, the flow rate of the wet ore is reduced through the blocking effect of the partition plate 3, and the wet ore enters the buffer area 15 by overcoming the partition plate 3, enters the distributor 5 through the opening 4, the flow rate of the ore is further reduced since the discharge hole 13 is also a certain height (not less than 400 mm) away from the bottom of the distributor 5, and the ore flows uniformly to the inclined discharge weir plate 6 through the discharge hole 13, the angle of the inclined discharge weir plate 6 can be adjusted through the manual pull rod 11, and the wear-resistant rubber 9 is paved on the inclined discharge weir plate 6, so that the ore is uniformly fed into the linear vibrating screen for classification operation.
[0018] The above description is only a specific implementation manner of the utility model, and various examples do not limit the essential content of the utility model.
